Cardiovascular health in Spain based on the Life's Essential 8 and its association with all-cause and cardiovascular mortality: the ENRICA cohort. REVISTA ESPANOLA DE CARDIOLOGIA (ENGLISH ED.) 2024; 77:372-380. [PMID: 37783370 DOI: 10.1016/j.rec.2023.09.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 09/07/2023] [Indexed: 10/04/2023]
Abstract
INTRODUCTION AND OBJECTIVES The American Heart Association has recently developed the Life's Essential 8 (LE8) score to encourage prevention of cardiovascular disease (CVD). This study assessed the distribution of LE8 in the Spanish adult population and its association with all-cause and CVD death. METHODS We used data from 11 616 individuals aged 18 years and older (50.5% women) from the ENRICA study, recruited between 2008 and 2010 and followed up until 2020 to 2022. The LE8 score includes 8 metrics (diet, physical activity, nicotine exposure, sleep health, body mass index, blood lipids and glucose, and blood pressure) and ranges from 0 to 100. The association of LE8 score with mortality was summarized with hazard ratios (HR), obtained from Cox regression. RESULTS In total, 13.2% of participants (range, 6.1%-16.9% across regions) had low cardiovascular health (LE8 ≤ 49). During a median follow-up of 12.9 years, 908 total deaths occurred, and, during a median follow-up of 11.8 years, 207 CVD deaths were ascertained. After adjustment for the main potential confounders and compared with being in the least healthy (lowest) quartile of LE8, the HR (95%CI) of all-cause mortality for the second, third and fourth quartiles were 0.68 (0.56-0.83), 0.63 (0.51-0.78), and 0.53 (0.39-0.72), respectively. The corresponding figures for CVD mortality, after accounting for competing mortality risks, were 0.62 (0.39-0.97), 0.55 (0.32-0.93), and 0.38 (0.16-0.89). CONCLUSIONS A substantial proportion of the Spanish population showed low cardiovascular health. A higher LE8 score, starting from the second quartile, was associated with lower all-cause and CVD mortality.

Dietary vitamin C intake and changes in frequency, severity, and location of pain in older adults. J Gerontol A Biol Sci Med Sci 2024:glae093. [PMID: 38644802 DOI: 10.1093/gerona/glae093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Indexed: 04/23/2024] Open
Abstract
BACKGROUND Oral vitamin C supplementation has been associated with lower risk of chronic postsurgical pain. However, the effect of dietary vitamin C on pain in a non-surgical setting is unknown. We aimed to investigate the association between dietary vitamin C intake and changes over time in chronic pain and its characteristics in community-dwelling adults aged 60+ years. METHODS We pooled data from participants of the Seniors-ENRICA-1 (n=864) and Seniors-ENRICA-2 (n=862) cohorts who reported pain at baseline or at follow-up. Habitual diet was assessed with a face-to-face diet history and dietary vitamin C intake was estimated using standard food composition tables. Pain changes over time were the difference between scores at baseline and follow-up obtained from a pain scale that considered the frequency, severity, and number of pain locations. Multivariable-adjusted relative risk ratios (RRR) were obtained using multinomial logistic regression. RESULTS After a median follow-up of 2.6 years, pain worsened for 696 (40.3%) participants, improved for 734 (42.5%), and did not change for 296 (17.2%). Compared to the lowest tertile of energy-adjusted vitamin C intake, those in the highest tertile had a higher likelihood of overall pain improvement (RRR 1.61 [95% confidence interval 1.07-2.41],p-trend 0.02). Higher vitamin C intake was also associated with lower pain frequency (1.57 [1.00-2.47],p-trend=0.05) and number of pain locations (1.75 [1.13-2.70],p-trend=0.01). CONCLUSIONS Higher dietary vitamin C intake was associated with improvement of pain and with lower pain frequency and number of pain locations in older adults. Nutritional interventions to increase dietary vitamin C intake with the aim of improving pain management require clinical testing.

Incorporating Cardiovascular Risk Assessment into Adolescent Reproductive Health and Primary Care Visits. J Pediatr Adolesc Gynecol 2024:S1083-3188(24)00207-9. [PMID: 38599564 DOI: 10.1016/j.jpag.2024.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 03/04/2024] [Accepted: 03/28/2024] [Indexed: 04/12/2024]
Abstract
STUDY OBJECTIVE This study aimed to evaluate the usability and feasibility of incorporating a cardiovascular risk assessment tool into adolescent reproductive health and primary care visits. DESIGN, SETTING, AND PARTICIPANTS We recruited 60 young women ages 13-21 years to complete the HerHeart web-tool in 2 adolescent clinics in Atlanta, GA. MAIN OUTCOME MEASURES Participants rated the tool's usability via the Website Analysis and Measurement Inventory (WAMMI, range 0-95) and their perceived 10-year and lifetime risk of cardiovascular disease (CVD) on a visual analog scale (range 0-10). Participants' perceived risk, blood pressure, and body mass index were measured at baseline and 3 months after enrollment. Health care providers (HCP, n = 5) completed the WAMMI to determine the usability and feasibility of incorporating the HerHeart tool into clinical practice. RESULTS Adolescent participants and HCPs rated the tool's usability highly on the WAMMI with a median of 79 (interquartile range [IQR] 65, 84) and 76 (IQR 71, 84). At the baseline visit, participants' median perceived 10-year risk of a heart attack was 1 (IQR 0, 3), and perceived lifetime risk was 2 (IQR 0, 4). Immediately after engaging with the tool, participants' median perceived 10-year risk was 2 (IQR 1, 4.3), and perceived lifetime risk was 3 (IQR 1.8, 6). Thirty-one participants chose to set a behavior change goal, and 12 participants returned for follow-up. Clinical metrics were similar at the baseline and follow-up visits. CONCLUSION HerHeart is acceptable to young women and demonstrates potential for changing risk perception and improving health habits to reduce risk of CVD. Future research should focus on improving retention in studies to promote cardiovascular health within reproductive health clinics.

Association of a Mediterranean Lifestyle With All-Cause and Cause-Specific Mortality: A Prospective Study from the UK Biobank. Mayo Clin Proc 2024; 99:551-563. [PMID: 37589638 DOI: 10.1016/j.mayocp.2023.05.031] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 05/12/2023] [Accepted: 05/31/2023] [Indexed: 08/18/2023]
Abstract
OBJECTIVE To examine the association between the Mediterranean lifestyle and all-cause, cancer, and cardiovascular disease (CVD) mortality in a British population. PATIENTS AND METHODS We studied 110,799 individuals 40 to 75 years of age from the UK Biobank cohort, free of CVD or cancer between 2009 and 2012 who were followed-up to 2021. The Mediterranean lifestyle was assessed at baseline through the Mediterranean Lifestyle (MEDLIFE) index, derived from the lifestyle questionnaire and diet assessments and comprising three blocks: (1) "Mediterranean food consumption," (2) "Mediterranean dietary habits," and (3) "physical activity, rest, social habits, and conviviality." Death information was retrieved from death register records. Cox regression models were used to analyze the study associations. RESULTS During a median 9.4-year follow-up, 4247 total deaths, 2401 cancer deaths, and 731 CVD deaths were identified. Compared with the first quartile of the MEDLIFE index, increasing quartiles had HRs of 0.89 (95% CI, 0.81 to 0.97), 0.81 (95% CI, 0.74 to 0.89), and 0.71 (95% CI, 0.65 to 0.78) (P-trend<.001 for all-cause mortality). For cancer mortality, the quartiles had HRs of 0.90 (95% CI, 0.80 to 1.01), 0.83 (95% CI, 0.74 to 0.93), and 0.72 (95% CI, 0.64 to 0.82) (P-trend<.001). All MEDLIFE index blocks were independently associated with lower risk of all-cause and cancer death, and block 3 was associated with lower CVD mortality. CONCLUSION Higher adherence to the Mediterranean lifestyle was associated with lower all-cause and cancer mortality in British middle-aged and older adults in a dose-response manner. Adopting a Mediterranean lifestyle adapted to the local characteristics of non-Mediterranean populations may be possible and part of a healthy lifestyle.

Exposure to green spaces, cardiovascular risk biomarkers and incident cardiovascular disease in older adults: The Seniors-Enrica II cohort. ENVIRONMENT INTERNATIONAL 2024; 185:108570. [PMID: 38484611 DOI: 10.1016/j.envint.2024.108570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 02/07/2024] [Accepted: 03/07/2024] [Indexed: 03/26/2024]
Abstract
INTRODUCTION The impact of residential green spaces on cardiovascular health in older adults remains uncertain. METHODS Cohort study involving 2114 adults aged ≥ 65 years without cardiovascular disease (CVD), residing in five dense municipalities (Prince et al., 2015) of the Madrid region and with detailed characterization of their socioeconomic background, health behaviors, CVD biological risk factors, and mental, physical, and cognitive health. Greenness exposure was measured using the Normalized Difference Vegetation Index (NDVI) at varying distances from participants' homes. Traffic exposure, neighborhood environment, neighborhood walkability, and socioeconomic deprivation at the census level were also assessed. Serum N-terminal pro-B-type natriuretic peptide (NT-ProBNP), high-sensitivity troponin T (hs-TnT), interleukin 6 (IL-6), and Growth Differentiation Factor 15 (GDF-15) were measured at baseline, and incident CVD events identified through electronic medical records (International Classification of Primary Care-2 codes K74, K75, K77, K90, and K92). RESULTS After adjusting for sex, age, educational attainment, financial hardship and socioeconomic deprivation at the census level, an interquartile range (IQR) increase in NDVI at 250, 500, 750, and 1000 m around participants' homes was associated with mean differences in ProBNP of -5.56 % (95 %CI: -9.77; -1.35), -5.05 % (-9.58; -0.53), -4.24 % (-8.19, -0.19), and -4.16 % (-7.59; -0.74), respectively; and mean differences in hs-TnT among diabetic participants of -8.03 % (95 %CI: -13.30; -2.77), -9.52 % (-16.08; -2.96), -8.05 % (-13.94, -2.16) and -5.56 % (-10.75; -0.54), respectively. Of similar magnitude, although only statistically significant at 250 and 500 m, were the observed lower IL-6 levels with increasing greenness. GDF-15 levels were independent of NDVI. In prospective analyses (median follow-up 6.29 years), an IQR increase in residential greenness at 500, 750, and 1000 m was associated with a lower risk of incident CVD. The variables that contributed most to the apparent beneficial effects of greenness on CVD were lower exposure to traffic, improved cardiovascular risk factors, and enhanced physical performance. Additionally, neighborhood walkability and increased physical activity were notable contributors among individuals with diabetes. CONCLUSION Increased exposure to residential green space was associated with a moderate reduction in CVD risk in older adults residing in densely populated areas.

Plant-Based Diets and Risk of Hip Fracture in Postmenopausal Women. JAMA Netw Open 2024; 7:e241107. [PMID: 38421643 PMCID: PMC10905300 DOI: 10.1001/jamanetworkopen.2024.1107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 01/14/2024] [Indexed: 03/02/2024] Open
Abstract
Importance Previous research has found that vegetarian diets are associated with lower bone mineral density and higher risk of fractures, but these studies did not differentiate the quality of the plant-based foods. Objective To examine the association between the quality of plant-based diets (not necessarily vegan but also omnivorous) and hip fracture risk among postmenopausal women in the Nurses' Health Study. Design, Setting, and Participants This cohort study analyzed data from 70 285 postmenopausal women who participated in the US Nurses' Health Study from 1984 through 2014. Data were analyzed from January 1 to July 31, 2023. Main outcomes and Measures Hip fractures were self-reported on biennial questionnaires. Diet was assessed every 4 years using a validated semiquantitative food frequency questionnaire. Plant-based diet quality was assessed using 2 previously established indices: the healthful Plant-Based Diet Index (hPDI), for which healthy plant foods (whole grains, fruits, vegetables, nuts, legumes, vegetable oils, and tea or coffee) received positive scores, whereas less healthy plant foods (fruit juices, sweetened beverages, refined grains, potatoes, and sweets or desserts) and animal foods received reversed scores; and the unhealthful Plant-Based Diet Index (uPDI), for which positive scores were given to less healthy plant foods and reversed scores to healthy plant and animal foods. Quintile scores of 18 food groups were summed, with a theoretical range for both indices of 18 to 90 (highest adherence). Cox proportional hazards regression with time-varying covariates was used to compute hazard ratios (HRs) and 95% CIs for hip fracture. Results In total, 70 285 participants (mean [SD] age, 54.92 [4.48] years; 100% White women) were included, and 2038 cases of hip fracture were ascertained during the study and for up to 30 years of follow-up. Neither the hPDI (HR for highest vs lowest quintile, 0.97 [95% CI, 0.83-1.14]) nor the uPDI (HR for highest vs lowest quintile, 1.02 [95% CI, 0.87-1.20]) for long-term diet adherence was associated with hip fracture risk. However, when examining recent intake for the highest vs lowest quintiles, the hPDI was associated with 21% lower risk of hip fracture (HR, 0.79 [95% CI, 0.68-0.92]; P = .02 for trend), and the uPDI was associated with 28% higher risk (1.28 [95% CI, 1.09-1.51]; P = .008 for trend). Conclusions and Relevance Findings of this cohort study indicated that long-term adherence to healthful or unhealthful plant-based diets as assessed by hPDI and uPDI scores was not associated with hip fracture risk. Future research should clarify whether the associations observed with recent dietary intake are due to short-term effects of these dietary patterns, reverse causality, or both.

Mediterranean lifestyle index and 24-h systolic blood pressure and heart rate in community-dwelling older adults. GeroScience 2024; 46:1357-1369. [PMID: 37561386 PMCID: PMC10828285 DOI: 10.1007/s11357-023-00898-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 07/28/2023] [Indexed: 08/11/2023] Open
Abstract
Specific foods, nutrients, dietary patterns, and physical activity are associated with lower blood pressure (BP) and heart rate (HR), but little is known about the joint effect of lifestyle factors captured in a multidimensional score. We assessed the association of a validated Mediterranean-lifestyle (MEDLIFE) index with 24-h-ambulatory BP and HR in everyday life among community-living older adults. Data were taken from 2,184 individuals (51% females, mean age: 71.4 years) from the Seniors-ENRICA-2 cohort. The MEDLIFE index consisted of 29 items arranged in three blocks: 1) Food consumption; 2) Dietary habits; and 3) Physical activity, rest, and conviviality. A higher MEDLIFE score (0-29 points) represented a better Mediterranean lifestyle adherence. 24-h-ambulatory BP and HR were obtained with validated oscillometric devices. Analyses were performed with linear regression adjusted for the main confounders. The MEDLIFE-highest quintile (vs Q1) was associated with lower nighttime systolic BP (SBP) (-3.17 mmHg [95% CI: -5.25, -1.08]; p-trend = 0.011), greater nocturnal-SBP fall (1.67% [0.51, 2.83]; p-trend = 0.052), and lower HR (-2.04 bpm [daytime], -2.33 bpm [nighttime], and -1.93 bpm [24-h]; all p-trend < 0.001). Results were similar for each of the three blocks of MEDLIFE and by hypertension status (yes/no). Among older adults, higher adherence to MEDLIFE was associated with lower nighttime SBP, greater nocturnal-SBP fall, and lower HR in their everyday life. These results suggest a synergistic BP-related protection from the components of the Mediterranean lifestyle. Future studies should determine whether these results replicate in older adults from other Mediterranean and non-Mediterranean countries.

Exposure to residential traffic and trajectories of unhealthy ageing: results from a nationally-representative cohort of older adults. Environ Health 2024; 23:15. [PMID: 38303067 PMCID: PMC10832178 DOI: 10.1186/s12940-024-01057-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 01/22/2024] [Indexed: 02/03/2024]
Abstract
BACKGROUND Traffic exposure has been associated with biomarkers of increased biological ageing, age-related chronic morbidities, and increased respiratory, cardiovascular, and all-cause mortality. Whether it is associated with functional impairments and unhealthy ageing trajectories is unknown. METHODS Nationally representative population-based cohort with 3,126 community-dwelling individuals aged ≥60 years who contributed 8,291 biannual visits over a 10 year period. Unhealthy ageing was estimated with a deficit accumulation index (DAI) based on the number and severity of 52 health deficits, including 22 objectively-measured impairments in physical and cognitive functioning. Differences in DAI at each follow-up across quintiles of residential traffic density (RTD) at 50 and 100 meters, and closest distance to a petrol station, were estimated using flexible marginal structural models with inverse probability of censoring weights. Models were adjusted for sociodemographic and time-varying lifestyle factors, social deprivation index at the census tract and residential exposure to natural spaces. RESULTS At baseline, the mean (SD) age and DAI score of the participants were 69.0 (6.6) years and 17.02 (11.0) %, and 54.0% were women. The median (IQR) RTD at 50 and 100 meters were 77 (31-467) and 509 (182-1802) vehicles/day, and the mean (SD) distance to the nearest petrol station of 962 (1317) meters. The average increase in DAI (95%CI) for participants in quintiles Q2-Q5 (vs Q1) of RTD at 50 meters was of 1.51 (0.50, 2.53), 0.98 (-0.05, 2.01), 2.20 (1.18, 3.21) and 1.98 (0.90, 3.05), respectively. Consistent findings were observed at 100 meters. By domains, most of the deficits accumulated with increased RTD were of a functional nature, although RTD at 50 meters was also associated with worse self-reported health, increased vitality problems and higher incidence of chronic morbidities. Living closer to a petrol station was associated with a higher incidence of functional impairments and chronic morbidities. CONCLUSIONS Exposure to nearby residential traffic is associated with accelerated trajectories of unhealthy ageing. Diminishing traffic pollution should become a priority intervention for adding healthy years to life in the old age.

Animal and vegetable protein intake and malnutrition in older adults: a multicohort study. J Nutr Health Aging 2024; 28:100002. [PMID: 38267163 DOI: 10.1016/j.jnha.2023.100002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 11/17/2023] [Accepted: 11/19/2023] [Indexed: 01/26/2024]
Abstract
OBJECTIVES Malnutrition is a global concern in older adults, as it negatively affects morbidity and mortality. While higher animal protein intake may help prevent and treat malnutrition, it might also increase the risk of chronic diseases and death. Conversely, vegetable protein intake might have a lower anabolic effect and not be as effective to improve nutritional status. We studied whether animal and vegetable protein intake are associated with changes in nutritional status in older adults. DESIGN We used pooled data from two Spanish cohorts: the Seniors-ENRICA 1 and Seniors-ENRICA 2. SETTINGS AND PARTICIPANTS 2,965 community-dwelling adults aged 62-92 years. MEASUREMENTS Protein intake was estimated at baseline via an electronic, validated diet history. Nutritional status was assessed at baseline and after 2.6 years with the GLIM (Global Leadership Initiative on Malnutrition) phenotypic criteria: weight loss, low body mass index, and reduced muscle mass. The odds of improvements in nutritional status were assessed with logistic regression models, extensively adjusted for potential confounders. RESULTS Higher animal and vegetable protein intake were associated with improvements in nutritional status [odds ratios (95% confidence intervals) per 0.25 g/kg/day were 1.15 (1.00, 1.32) and 1.77 (1.35, 2.32), respectively]. Cereal protein intake drove most of the latter association [2.07 (1.44, 2.98)]. Replacing 0.25 g/kg/day of total animal protein, meat, or fish protein (but not dairy or egg protein) with vegetable protein was associated with improvements in nutritional status [1.54 (1.13, 2.09), 1.70 (1.20, 2.41), and 1.77 (1.18, 2.64), respectively]. CONCLUSIONS Higher animal and, especially, vegetable protein intake were associated with improvements in nutritional status in older adults. Replacing total animal protein, meat, or fish protein with vegetable protein may help improve malnutrition.

Abstract
OBJECTIVE To assess the association of physical activity (PA) type, volume, intensity, and changes over time with all-cause mortality in older adults. METHODS We used data from 3518 and 3273 older adults recruited in the Seniors-ENRICA-1 and 2 cohorts. PA was assessed with the EPIC questionnaire. Participants reported how many hours they spent a week in walking, cycling, gardening, do-it-yourself (DIY), sports, and housework. Then, time at each intensity (moderate PA [MPA], vigorous PA [VPA], moderate-to-vigorous PA [MVPA] and total PA) was calculated. Changes in PA were calculated from the date of the baseline interview to Wave 1. All-cause mortality was ascertained up January 31, 2022. Analyses were performed with Cox regression models, adjusting for the main confounders. RESULTS Walking, gardening, sports, and housework was associated with lower mortality (ranged 20%-46%). Also, MPA, VPA, MVPA was associated with lower risk of mortality (ranged 28%-53%). Analyses of PA change showed that, compared no PA participation (at baseline nor Wave 1), maintain walking, sports, and housework (ranged 28%-53%) and maintaining MPA, VPA, and MVPA (ranged 32%-36%) levels was linked to decreased mortality risk. Those who increased, maintained, or even decreased total PA had lower mortality (57%, 52%, and 36%, respectively) than those with consistently very low PA. CONCLUSIONS The lower mortality was observed in those with a high baseline level of total PA. Maintaining PA levels such as walking, gardening, and housework, or at all analyzed intensities, was related to lower mortality.

Blood Selenium Concentrations Are Inversely Associated with the Risk of Undernutrition in Older Adults. Nutrients 2023; 15:4750. [PMID: 38004143 PMCID: PMC10674362 DOI: 10.3390/nu15224750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 10/13/2023] [Accepted: 11/09/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND Selenium is an essential trace element with an antioxidant and anti-inflammatory capacity that has been associated in experimental studies with beneficial effects on appetite control, the regulation of the gut microbiota, and control of the anabolic-catabolic balance. The main aim of the present study was to evaluate the association between circulating selenium concentrations and the risk of developing undernutrition in older adults. METHODS This was a cohort study with 1398 well-nourished community-dwelling individuals aged ≥ 65 years residing in Spain in 2017, who were followed for a mean of 2.3 years. Whole blood selenium was measured at baseline using inductively coupled plasma-mass spectrometry. Undernutrition was assessed at baseline and at follow-up, and defined as having at least one of the three GLIM phenotypic criteria (involuntary weight loss, a low body mass index, and a reduced muscle mass) and at least one of the two etiologic criteria (reduced food consumption or nutrient assimilation and inflammation/disease burden). RESULTS During the follow-up, 142 participants (11%) developed moderate undernutrition and 113 (8.8%) severe undernutrition. The standardized relative risks of moderate and severe undernutrition at the 75th percentile of Se levels versus the 25th were 0.90 and 0.70, respectively. In dose-response analyses, the risk of severe undernutrition decreased linearly with increasing selenium concentrations. This association was independent of protein intake or diet quality and was stronger among participants with a diagnosis of a musculoskeletal disorder. CONCLUSIONS The results suggest that an adequate dietary selenium status is needed to prevent undernutrition in older adults. Also, this may open the door for clinical trials with selenium supplementation, at doses considered as safe, to prevent undernutrition.

Abstract
In the United States (US), new firefighters' fitness and health behaviors deteriorate rapidly after fire academy graduation. Over the long-term, this increases their risks for chronic diseases. This study protocol describes the proposed usability testing and pilot study of a newly designed and developed healthy lifestyle smartphone app, "Surviving & Thriving", tailored towards young US firefighters. "Surviving & Thriving" will provide interactive educational content on four lifestyle factors; nutrition, sleep, physical activity, and resilience, and include a personalized journey, habit tracker, and elements of gamification to promote engagement and long-term healthy behavior change. The first phase of the app development entails alpha testing by the research team and pre-beta testing by a fire service expert panel which will help refine the app into a pre-consumer version. Upon completion of the full app prototype, beta 'usability' testing will be conducted among new fire academy graduates from two New England fire academies to collect qualitative and quantitative feedback via focus groups and satisfaction surveys, respectively. A last phase of piloting the app will evaluate the app's efficacy at maintaining/improving healthy lifestyle behaviors, mental health metrics, and physical fitness metrics. We will also evaluate whether firefighters' perceived "health cultures" scores (ratings of each fire station's/fire department's environments as to encouraging/discouraging healthy behaviors) modify the changes in health metrics after utilizing the app for three to six months. This novel user-friendly app seeks to help new firefighters maintain/improve their health and fitness more effectively, reducing their risk of lifestyle-related chronic disease. Firefighters who can establish healthy habits early in their careers are more likely to sustain them throughout their lives.

Association between a mediterranean lifestyle and Type 2 diabetes incidence: a prospective UK biobank study. Cardiovasc Diabetol 2023; 22:271. [PMID: 37794451 PMCID: PMC10552305 DOI: 10.1186/s12933-023-01999-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 09/19/2023] [Indexed: 10/06/2023] Open
Abstract
BACKGROUND There is mounting evidence that the Mediterranean diet prevents type 2 diabetes, but little is known about the role of Mediterranean lifestyles other than diet and among non-Mediterranean populations. This work aimed to examine the association between a comprehensive Mediterranean-type lifestyle and type 2 diabetes incidence in a British adult population. METHODS We used data from 112,493 individuals free of cardiovascular disease and type 2 diabetes mellitus, aged 40-69 years, from the UK Biobank cohort, who were followed from 2009 to 2010 to 2021. The Mediterranean lifestyle was assessed through the 25-item MEDLIFE index, which comprises three blocks: (a) "Mediterranean food consumption", (b) "Mediterranean dietary habits", (c) "Physical activity, rest, social habits, and conviviality". Diabetes incidence was obtained from clinical records. Cox proportional-hazards regression models were used to analyze associations and adjusted for the main potential confounders. RESULTS After a median follow-up of 9.4 years, 2,724 cases of type 2 diabetes were ascertained. Compared to the first quartile of MEDLIFE adherence, the hazard ratios (95% confidence interval) for increasing quartiles of adherence were 0.90 (0.82-0.99), 0.80 (0.72-0.89) and 0.70 (0.62-0.79) (p-trend < 0.001). All three blocks of MEDLIFE were independently associated with lower risk of diabetes. CONCLUSIONS Higher adherence to the MEDLIFE index was associated with lower risk of type 2 diabetes in the UK Biobank. A Mediterranean-type lifestyle, culturally adapted to non-Mediterranean populations, could help prevent diabetes.

Effect of a Nutrition Intervention on Mediterranean Diet Adherence Among Firefighters: A Cluster Randomized Clinical Trial. JAMA Netw Open 2023; 6:e2329147. [PMID: 37589978 PMCID: PMC10436136 DOI: 10.1001/jamanetworkopen.2023.29147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Accepted: 07/09/2023] [Indexed: 08/18/2023] Open
Abstract
Importance US firefighters are a working population at risk of chronic diseases, including obesity, cardiovascular disease, and cancer. This risk may be mitigated by a healthy diet. Objective To evaluate the effect of a Mediterranean nutrition intervention using a behavioral/environmental approach (firefighter/fire station/home) at the individual participant level. Design, Setting, and Participants This 12-month cluster randomized clinical trial included US career firefighters from fire stations and homes within 2 Indiana fire departments. Participants were randomized by fire station to either Mediterranean diet or control (usual care). The study was conducted from October 2016 to December 2019, and data were analyzed in November 2022. Intervention For the first 12 months of the study, firefighters located at fire stations randomized to the intervention group were provided with access to supermarket discounts and free samples of Mediterranean diet foods, online nutrition education platforms, email announcements and reminders, family and peer education and support, and chef demonstrations. Firefighters in fire stations allocated to the control group received no intervention and were instructed to follow their usual diet. Main Outcomes and Measures Change in dietary habits at 12 months as measured by a modified Mediterranean diet score (range, 0 to 51 points) at baseline and 6-month and 12-month follow-up. Cardiometabolic parameters were secondary outcomes. Results Of 485 included firefighters, 458 (94.4%) were male, and the mean (SD) age was 47 (7.5) years. A total of 241 firefighters (27 fire stations) were randomized to the Mediterranean nutrition intervention, and 244 (25 fire stations) were randomized to usual diet. Outcomes were analyzed using generalized linear mixed models for modified Mediterranean diet score at 6 months (n = 336) and 12 months (n = 260), adjusting for baseline age, sex, race and ethnicity, fire department, physical activity, and waist circumference. In the intervention group compared with the control group, the modified Mediterranean diet score significantly increased by 2.01 points (95% CI, 0.62-3.40; P = .005) at 6 months and by 2.67 points (95% CI, 1.14-4.20; P = .001) at 12 months. Among secondary outcomes, changes in cardiometabolic risk factors were not statistically significant at 1 year. Results from analyses with multilevel multiple imputation for missingness were similar. Conclusions and Relevance In this Mediterranean nutrition intervention of multicomponent behavioral/environmental changes, career firefighters had increased adherence to a Mediterranean diet. Trial Registration ClinicalTrials.gov Identifier: NCT02941757.

Mediterranean Diet-Based Interventions to Improve Anthropometric and Obesity Indicators in Children and Adolescents: A Systematic Review with Meta-Analysis of Randomized Controlled Trials. Adv Nutr 2023; 14:858-869. [PMID: 37127186 PMCID: PMC10334150 DOI: 10.1016/j.advnut.2023.04.011] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 04/24/2023] [Accepted: 04/27/2023] [Indexed: 05/03/2023] Open
Abstract
To our knowledge, no systematic review with meta-analysis has separately synthesized the effects of Mediterranean diet-based interventions in children and adolescents in relation to the effects on anthropometric measures. A better understanding of the effects of Mediterranean diet-based interventions on anthropometric variables could facilitate their implementation in efforts to prevent obesity in the young population. The aim of the present meta-analysis was to evaluate the effects of Mediterranean diet-based interventions on anthropometric and obesity indicators among children and adolescents. Four databases were systematically searched (PubMed, Scopus, Web of Science, and Cochrane Database of Systematic Reviews), including all studies up until 15 March, 2023. Eligible articles were randomized controlled trials measuring the effect of an intervention based on the promotion of the Mediterranean diet and obesity-associated parameters. The effect size of each study was estimated by Cohen's d for continuous variables or risk difference for categorical variables. Compared to the control group, the Mediterranean diet-based interventions showed small and significant reductions in body mass index (d = -0.14; 95% CI: -0.26, -0.01; I2 = 77.52%). Participants in the Mediterranean diet-based interventions had a significant reduction in the percentage of obesity (risk difference = 0.12; 95% CI: 0.01, 0.23; I2 = 84.56%) in comparison with the control group. Interventions had greater effects when aiming at participants with excess weight (that is, overweight or obesity), both for body mass index, waist circumference, waist-to-height ratio, percentage of obesity, and percentage of abdominal obesity. Mediterranean diet-based interventions have a significant effect on reducing the body mass index as well as reducing obesity in children and adolescents (aged 3-18 y). This trial was registered at PROSPERO as CRD42023386789.

Abstract
OBJECTIVES To validate the diagnoses of acute myocardial infarction (AMI) and stroke recorded in electronic medical records (EMR) and to estimate the population prevalence of both diseases in people aged ≥18 years. DESIGN Cross-sectional validation study. SETTING 45 primary care centres. PARTICIPANTS Simple random sampling of diagnoses of AMI and stroke (International Classification of Primary Care-2 codes K75 and K90, respectively) registered by 55 physicians and random age-matched and sex-matched sampling of the records that included in primary care EMRs in Madrid (Spain). PRIMARY AND SECONDARY OUTCOME MEASURES Sensitivity, specificity, positive and negative predictive values and overall agreement were calculated using the kappa statistic. Applied gold standards were ECGs, brain imaging studies, hospital discharge reports, cardiology reports and neurology reports. In the case of AMI, the ESC/ACCF/AHA/WHF Expert Consensus Document was also used. Secondary outcomes were the estimated prevalence of both diseases considering the sensitivity and specificity obtained (true prevalence). RESULTS The sensitivity of a diagnosis of AMI was 98.11% (95% CI, 96.29 to 99.03), and the specificity was 97.42% (95% CI, 95.44 to 98.55). The sensitivity of a diagnosis of stroke was 97.56% (95% CI, 95.56 to 98.68), and the specificity was 94.51% (95% CI, 91.96 to 96.28). No differences in the results were found after stratification by age and sex (both diseases). The prevalence of AMI and stroke was 1.38% and 1.27%, respectively. CONCLUSION The validation results show that diagnoses of AMI and stroke in primary care EMRs constitute a helpful tool in epidemiological studies. The prevalence of AMI and stroke was lower than 2% in the population aged over 18 years.

Performance and validation of the Healthy Heart Score model for predicting 12-year cardiovascular mortality in a nationwide Mediterranean population. REVISTA ESPANOLA DE CARDIOLOGIA (ENGLISH ED.) 2023; 76:444-452. [PMID: 36379366 DOI: 10.1016/j.rec.2022.10.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Accepted: 10/26/2022] [Indexed: 05/28/2023]
Abstract
INTRODUCTION AND OBJECTIVES The Healthy Heart Score (HHS) is a lifestyle-based equation for predicting cardiovascular disease (CVD) risk and may serve as a tool in primordial prevention. However, its performance outside North American populations is unknown. This study assessed the performance of the HHS for estimating CVD mortality in the adult population of Spain. METHODS We analyzed data from the ENRICA cohort, comprising 10 228 participants free of chronic disease and representative of the Spanish population aged ≥ 18-years, who were recruited from 2008 to 2010 and were followed up to 2020. The HHS includes body mass index, alcohol, physical activity, smoking, and a 5-component dietary score. The HHS was calculated at baseline using the sex-specific beta coefficients from the original development cohorts. Model discrimination was assessed using the Harrell c-statistic and Gonen-Heller c-statistic for survival data, and calibration was evaluated through calibration plots. RESULTS After a median follow-up of 11.8 years, 110 CVD deaths were ascertained. The discrimination of the HHS was similar for women (Harrell c, 0.91; 95%CI, 0.87-0.95; Gonen-Heller-c, 0.85; 95%CI, 0.83-0.88) and men (Harrell c, 0.91; 95%CI, 0.88-0.94; Gonen-Heller c: 0.85; 95%CI, 0.83-0.88). After recalibration by the sex-specific baseline survival function, the calibration became optimal for: a) all deciles of predicted CVD risk except the highest decile, where HHS underestimated the risk, and b) all age groups except 70 years and older, where there was an underestimation. CONCLUSIONS In this Spanish cohort, the HHS showed good discrimination and calibration for predicting CVD death. The performance of HHS in other European populations and its implementation in the clinical setting warrants further investigation.

The role of lifestyle in the association between frailty and all-cause mortality amongst older adults: a mediation analysis in the UK Biobank. Age Ageing 2023; 52:afad092.

Abstract
OBJECTIVE frailty is a syndrome characterised by increased vulnerability to stressors, which manifests as higher death risk. Whilst guidelines for frailty management usually entails lifestyle modifications (e.g. physical exercise, diet), the mediating role of lifestyle on the excess mortality associated with frailty is unclear. This study estimates the death risk due to frailty that could be avoided with a healthy lifestyle in older adults. SUBJECTS AND METHODS we analysed data from 91,906 British individuals aged ≥60 years recruited between 2006 and 2010. At baseline, frailty was identified according to Fried's phenotype, and a four-item Healthy Lifestyle Index (HLS) was calculated based on physical activity, diet, smoking and alcohol consumption. Mortality was ascertained from baseline through 2021. A mediation analysis under the counterfactual framework was performed adjusting for the main confounders. RESULTS during a median follow-up of 12.5 years, 9,383 deaths occurred. Frailty was directly associated with all-cause mortality (hazard ratio: 2.30 [95% confidence interval {CI} 2.07, 2.54]), and inversely associated with the HLS (ß: -0.45 points [-0.49, -0.40]). The hazard ratio [95%CI] for the direct effect of frailty on mortality was 2.12 [1.91, 2.34], whilst for the indirect effect (mediated by HLS) was 1.08 [1.07, 1.10]. The mediated proportion of HLS on mortality was 13.55% [11.26, 16.20], with physical activity having the highest proportion amongst the four HLS items (7.69% [5.00, 10.40]). CONCLUSIONS a healthy lifestyle partly mediates the association between frailty and mortality in British older adults. Since this was an exploratory mediation analysis, these results should be specifically tested in future research.

Association of blood manganese concentrations with 24-h based brachial and central blood pressure, and pulse-wave velocity. ENVIRONMENTAL RESEARCH 2023; 225:115625.

Abstract
Potential environmental determinants of BP and hypertension in older adults are far less known than their lifestyle risk factors. Manganese (Mn) is an essential element for life that may induce changes in blood pressure (BP), but the direction of the association is unclear. We aimed to examine the association of blood manganese (bMn) with 24-h-based brachial, central BP (cBP), and pulse-wave velocity (PWV). With this purpose, we analyzed data from 1009 community-living adults aged >65 years without BP medication. bMn was measured using inductively-coupled plasma-mass spectrometry and 24-h BP with validated devices. The association of bMn (median: 6.77 μg/L; IQR: 5.59-8.27) with daytime brachial and central systolic (SBP) and with diastolic BP (DBP) was non-linear, with BP increases up to around the median of Mn and then stabilization or slight rightward decrease. Mean BP differences (95% confidence interval) comparing Mn Q2 to Q5 (vs Q1 quintile) for brachial daytime SBP were 2.56 (0.22; 4.90), 3.59 (1.22; 5.96), 3.14 (0.77; 5.51) and 1.72 (-0.68; 4.11) mmHg, respectively; and 2.22 (0.70, 3.73), 2.55 (1.01, 4.08), 2.45 (0.91; 3.98), and 1.68 (0.13; 3.24), respectively, for DBP. Daytime central-pressures showed a similar dose-response relationship with bMn as daytime brachial-pressures. The association with nighttime BP was linearly positive for brachial BPs, and only increasing for Q5 for cBP. Regarding PWV, a tendency to significant linear increase along bMn levels was observed (p-trend = 0.042). The present findings extend the scarce evidence on the association between Mn and brachial BP to 2 other vascular parameters, suggesting Mn levels as a candidate risk factor for increasing levels of both brachial and cBPs in older adults, yet further research is needed with larger cohort studies in adults at all age ranges.

Abstract
Background:
There is strong evidence that the Mediterranean diet protects from cardiovascular disease (CVD); however, beyond diet, the Mediterranean lifestyle may have synergistic effects through the combination of other health behaviors, such as adequate rest or sociability. While most evidence on this lifestyle pattern comes from Mediterranean countries, little is known about the health effects of a Mediterranean lifestyle in non-Mediterranean populations. Our aim was to examine the association between a Mediterranean lifestyle index (MEDLIFE) and all-cause, (CVD), and cancer mortality in a British population.
Methods:
We used data from 110,799 individuals free of CVD or cancer, aged 40-69 years, from the UK Biobank cohort, who were followed from 2006-2010 to 2020. The Mediterranean lifestyle was assessed through the validated 26-item MEDLIFE index derived from the lifestyle questionnaire and from 2 or more Oxford WebQ Online 24-hour diet recalls. MEDLIFE comprised three blocks: a) Block 1 (13 items): Mediterranean food consumption, b) Block 2 (7 items): Mediterranean dietary habits, c) Block 3 (6 items): Physical activity, rest, social habits, and conviviality. Mortality was obtained from the death register records. Multivariable-adjusted Cox proportional-hazards regression models were used to analyse associations between MEDLIFE and all-cause, CVD, and cancer mortality.
Results:
After a mean 9.4-year follow-up, 4,247 deaths were identified. Higher adherence to the MEDLIFE index was associated with lower all-cause and cancer mortality in a dose-response manner. Compared to the first quartile of adherence to the MEDLIFE, the increasingly higher quartiles had a HR (95% CI) of 0.89 (0.81 -0.97), 0.81 (0.74-0.89) and 0.71 (0.65-0.78), p-trend <0.001, for all-cause mortality; and 0.90 (0.80-1.01), 0.83 (0.74-0.93) and 0.72 (0.64-0.82),
p
-trend <0.001, for cancer mortality. All MEDLIFE blocks were independently associated with lower risk of all-cause and cancer death, and block 3 with lower CVD mortality.
Conclusions:
A Mediterranean lifestyle was associated to reduced all-cause and cancer-mortality in British middle-aged and older adults; this suggests that adopting a Mediterranean lifestyle adapted to the local characteristics of non-Mediterranean populations is possible and can be part of a healthy lifestyle.

Abstract
Background:
United States (US) career firefighters represent a working population at high risk for cardiovascular disease that may benefit from a Mediterranean diet (MedDiet) nutrition intervention (MDNI). The
Feeding America’s Bravest
trial was the first workplace randomized controlled trial with nutrition education, behavior change, and incentives strategies promoting adherence to the MedDiet within US firehouses and homes. We assessed the hypothesis that a 12-month MDNI with a novel worksite behavior change approach would increase adherence to the MedDiet.
Methods:
486 US career firefighters within the Indianapolis and Fishers Fire Departments were enrolled and cluster randomized by fire station to either a MDNI or control group and completed 6-month (n=336) and 12-month follow-up (n=260). Stepwise-selection regression analyses and nested least-squares linear regression models determined the contribution of each item to the between person variability of a modified Mediterranean Diet Score (mMDS). To assess the intervention effect, an intention-to-treat analysis used multilevel mixed-effects linear regression models for repeated measures to evaluate between-group and within-group mean differences in mMDS from baseline to 6-months and baseline to 12-months adjusting for age, sex, physical activity, race, and waist circumference with clusters as the random effects parameter.
Results:
Among 484 US career firefighters (95% male with mean age of 47 years (SD=7.5; range: 26-68) observed mean scores (SD) in the MDNI group were 23.41 (6.34) at baseline, 25.26 (5.73) at 6-months, and 24.79 (6.15) at 12-months, and in the control group; 22.87 (6.78), 26.20 (6.15), and 26.68 (6.42), respectively. Between person variability of mMDS scores was largely due to the cooking oil used at home, fried foods, beverages at home, vegetables, and quantity of alcohol. Adjusted mean changes in mMDS showed statistically significant improvements among the MDNI group at 6-months by 1.28 points (pts.) (95%CI: -0.24 to 2.81) and 1.93 pts. (95%CI: 0.39 to 3.46) at 12 months compared to the control group. Multiple imputation methods supported these findings showing 6-month improvements of 1.23 pts. (95%CI: 0.22 to 2.25) and 1.63 pts. (95%CI: 0.58 to 2.67) at 12-months in the MDNI group compared to the control group.
Conclusions:
In conclusion, firefighters’ increased mMDS scores evidenced the effect of a multicomponent MDNI in a non-Mediterranean working population at high cardiovascular risk. Although more research is warranted, these findings support MedDiet promotion among the US fire service and other similar workforces. Furthermore, the intervention strategies used in this trial; cooking demonstrations, positive reinforcement, family involvement, and discounted access to staple MedDiet foods, may serve as effective nutrition worksite approaches for reducing the burden of chronic disease.

Abstract
Introduction:
Cardiovascular disease (CVD) remains the leading cause of death for women in the US, yet many young women are unaware of their lifetime risk of CVD. We employed user-centered design principles to adapt a validated CVD risk prediction tool for young women.
Hypothesis:
We hypothesized that young women would rate the tool (HerHeart) as user-friendly, be likely to recommend it to their friends, experience a change in their perceived risk of CVD, and report intent to change their health habits after engaging with it.
Methods:
We recruited 13 young women ages 13-21 from two clinical practices in Atlanta, GA to engage with the HerHeart CVD risk prediction tool. Participants rated the tool’s usability via the Website Analysis and Measurement Inventory (WAMMI), which is scored from 0 to 100. Participants rated their perceived 10-year and lifetime risk of CVD on a visual analog scale from 0 (Never going to happen) to 10 (Definitely will happen) before and after completing the tool. Participants reported their likelihood of recommending the tool to their friends and changing their health habits from 0 (Not likely at all) to 10 (Extremely likely).
Results:
Participants rated the tool’s usability highly on the WAMMI (M = 78.62 +/- 9.70). Participants’ perceived 10-year risk of a heart attack increased from a mean of 0.85 +/- 0.99 to 1.83 +/- 1.90, and perceived lifetime risk increased from a mean of 2.38 +/- 2.72 to 2.75 +/- 2.63, on the 10-point scale after engaging with the tool. Participants were more than likely to recommend HerHeart to their friends (M = 8.00 +/- 2.22) and to report intent to change their health habits (M = 8.82 +/- 1.47) after completing the tool. Participant data captured in the HerHeart tool are shown in the Table.
Conclusions:
The HerHeart tool is acceptable to young women and demonstrates potential for changing their risk perception and improving their health habits to reduce their risk of CVD. Recruitment is ongoing and will include input from clinicians on the feasibility of incorporating the tool in clinical practice.

Abstract
PURPOSE We aimed to prospectively investigate the association of an overall oxidative balance score (OBS) with all-cause death and cause-specific mortality among participants in the Seguimiento Universidad de Navarra (SUN) Study, a Mediterranean cohort of Spanish graduates. METHODS Using baseline information on 12 a priori selected dietary and non-dietary lifestyle pro- and antioxidants exposures-vitamins C and E, β-carotenes, selenium, zinc, heme iron, polyphenols, total antioxidant capacity, body mass index, alcohol, smoking, and physical activity-we constructed an equally weighted OBS categorized into quartiles, with higher scores representing greater antioxidant balance. Cox proportional hazards models were fitted to evaluate the association between the OBS and mortality. RESULTS A total of 18,561 participants (mean [SD] age, 38.5 [12.4] years; 40.8% males) were included in the analysis. During a median follow-up of 12.2 years (interquartile range 8.3-14.9), 421 deaths were identified, including 80 deaths from cardiovascular disease (CVD), 215 from cancer, and 126 from other causes. After adjustment for potential confounders, the hazard ratios and 95% confidence interval (CIs) between the highest quartile (predominance of antioxidants) vs. the lowest quartile (reference category) were 0.35 (95% CI 0.22-0.54, P-trend < 0.001) for all-cause mortality, 0.18 (95% CI 0.06-0.51, P-trend = 0.001) for CVD mortality, 0.35 (95% CI 0.19-0.65, P-trend = 0.002) for cancer mortality, and 0.45 (95% CI 0.20-1.02, P-trend = 0.054) for other-cause mortality. CONCLUSION Our findings suggest a strong inverse association between the OBS and all-cause, CVD, and cancer mortality. Individuals exposed to both antioxidant dietary and lifestyle factors may potentially experience the lowest mortality risk.

Association between a Mediterranean lifestyle and growth differentiation factor 15: The seniors ENRICA-2 cohort. Free Radic Biol Med 2023; 195:192-198. [PMID: 36584798 DOI: 10.1016/j.freeradbiomed.2022.12.090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 12/22/2022] [Accepted: 12/24/2022] [Indexed: 12/28/2022]
Abstract
BACKGROUND Growth Differentiation Factor 15 (GDF-15) is a marker of inflammation and oxidative stress that has been associated with multiple age-related chronic diseases. Since lifestyle is key for preventing these adverse health outcomes, we examined the association between a Mediterranean lifestyle and GDF-15 serum concentrations in Spanish older adults. METHODS We used cross-sectional data from 2502 older adults participating in the Seniors ENRICA-2 cohort. Adherence to the Mediterranean lifestyle was assessed with the 27-item MEDLIFE index, divided into three blocks: 1) "Mediterranean food consumption, 2) Mediterranean dietary habits, 3) Physical activity, rest, social habits, and conviviality". Analyses of the association between the MEFLIFE index and GDF-15 concentrations were performed using multivariable linear regression models adjusting for the main potential confounders. RESULTS The MEDLIFE index was inversely associated with GDF-15. Compared with participants in the lowest quartile of the MEDLIFE score, GDF-15 mean percentage differences (95% CI) were -3.0% (-8.0, 2.3) for the second quartile, -8.7% (-13.0, -4.1) for the third quartile, and -10.1% (-15.0, -4.9) for the fourth quartile (p-trend<0.001). Block 3 of MEDLIFE, and particularly doing sufficient physical activity, adequate sleep duration, and participating in collective sports, was individually linked to lower concentrations of GDF-15. Results remained similar after excluding participants with cardiovascular disease, type 2 diabetes, or obesity. CONCLUSIONS A Mediterranean lifestyle was associated with reduced levels of GDF-15, suggesting that a combination of multiple lifestyles may be an integral approach to reduce chronic inflammation and disease burden in older adults.

Real-world data in primary care: validation of diagnosis of atrial fibrillation in primary care electronic medical records and estimated prevalence among consulting patients'. BMC PRIMARY CARE 2023; 24:4. [PMID: 36600196 PMCID: PMC9811753 DOI: 10.1186/s12875-022-01961-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Accepted: 12/28/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND Primary care electronic medical records contain clinical-administrative information on a high percentage of the population. Before this information can be used for epidemiological purposes, its quality must be verified. This study aims to validate diagnoses of atrial fibrillation (AF) recorded in primary care electronic medical records and to estimate the prevalence of AF in the population attending primary care consultations. METHODS We performed a cross-sectional validation study of all diagnoses of AF recorded in primary care electronic medical records in Madrid (Spain). We also performed simple random sampling of diagnoses of AF (ICPC-2 code K78) registered by 55 physicians and random age- and sex-matched sampling of the records that included a diagnosis of AF. Electrocardiograms, echocardiograms, and hospital discharge or cardiology clinic reports were matched. Sensitivity, specificity, positive and negative predictive values (PPV and NPV), and overall agreement were calculated using the kappa statistic (κ). The prevalence of AF in the community of Madrid was estimated considering the sensitivity and specificity obtained in the validation. All calculations were performed overall and by sex and age groups. RESULTS The degree of agreement was very high (κ = 0.952), with a sensitivity of 97.84%, specificity of 97.39%, PPV of 97.37%, and NPV of 97.85%. The prevalence of AF in the population aged over 18 years was 2.41% (95%CI 2.39-2.42% [2.25% in women and 2.58% in men]). This increased progressively with age, reaching 16.95% in those over 80 years of age (15.5% in women and 19.44% in men). CONCLUSIONS The validation results obtained enable diagnosis of AF recorded in primary care to be used as a tool for epidemiological studies. A high prevalence of AF was found, especially in older patients.

Abstract
BACKGROUND AND OBJECTIVES A Mediterranean lifestyle may prevent and mitigate cardiometabolic disorders. We explored whether adherence to a Mediterranean lifestyle was prospectively associated with the risk of metabolic syndrome (MetS) among coronary heart disease (CHD) patients. METHODS The Coronary Diet Intervention with Olive Oil and Cardiovascular Prevention (CORDIOPREV) study was an interventional diet study to compare a Mediterranean diet with a low-fat diet, in 1002 CHD patients. The Mediterranean lifestyle (MEDLIFE) index was used to assess adherence to a MEDLIFE at baseline, and after 5 years, in 851 participants from the CORDIOPREV study. Subjects were classified as having high (>13 points), moderate (12-13 points), and low (<12 points) adherence to the MEDLIFE. Multivariable logistic regression models were used to determine the association between MEDLIFE adherence and the risk of MetS development or reversal. RESULTS During the 5-year follow-up, CORDIOPREV participants with high adherence to MEDLIFE had a lower risk of MetS development (odds ratio [OR] 0.37, 95% confidence interval [CI] 0.19-0.75, p < 0.01) and a higher likelihood of reversing preexisting MetS (OR 2.08 CI 95% 1.11-3.91, p = 0.02) compared with participants in the low MEDLIFE adherence group. Each additional one-point increment in the MEDLIFE index was associated with a 24% lower risk of MetS development (OR 0.76, 95% CI 0.64-0.90, p < 0.01) and a 21% higher likelihood of reversing preexisting MetS (OR 1.21 CI 95% 1.04-1.41, p = 0.01). CONCLUSIONS Our results showed that greater adherence to a MEDLIFE reduced the risk of subsequent MetS development and increased the likelihood of reversing preexisting MetS among patients with CHD at baseline.

Abstract
BACKGROUND Cardiovascular disease (CVD) is the leading cause of death among women in the United States. A considerable number of young women already have risk factors for CVD. Awareness of CVD and its risk factors is critical to preventing CVD, yet younger women are less aware of CVD prevalence, its risk factors, and preventative behaviors compared to older women. OBJECTIVE The purpose of this study is to assess CVD awareness among adolescent and young adult women and develop a lifestyle-based cardiovascular risk assessment tool for the promotion of CVD awareness among this population. METHODS This study used a 3-phase iterative design process with young women and health care practitioners from primary care and reproductive care clinics in Atlanta, Georgia. In phase 1, we administered a modified version of the American Heart Association Women's Health Survey to young women, aged 15-24 years (n=67), to assess their general CVD awareness. In phase 2, we interviewed young women, aged 13-21 years (n=10), and their health care practitioners (n=10), to solicit suggestions for adapting the Healthy Heart Score, an existing adult cardiovascular risk assessment tool, for use with this age group. We also aimed to learn more about the barriers and challenges to health behavior change within this population and the clinical practices that serve them. In phase 3, we used the findings from the first 2 phases to create a prototype of a new online cardiovascular risk assessment tool designed specifically for young women. We then used an iterative user-centered design process to collect feedback from approximately 105 young women, aged 13-21 years, as we adapted the tool. RESULTS Only 10.5% (7/67) of the young women surveyed correctly identified CVD as the leading cause of death among women in the United States. Few respondents reported having discussed their personal risk (4/67, 6%) or family history of CVD (8/67, 11.9%) with a health care provider. During the interviews, young women reported better CVD awareness and knowledge after completing the adult risk assessment tool and suggested making the tool more teen-friendly by incorporating relevant foods and activity options. Health care practitioners emphasized shortening the assessment for easier use within practice and discussed other barriers adolescents may face in adopting heart-healthy behaviors. The result of the iterative design process was a youth-friendly prototype of a cardiovascular risk assessment tool. CONCLUSIONS Adolescent and young adult women demonstrate low awareness of CVD. This study illustrates the potential value of a cardiovascular risk assessment tool adapted for use with young women and showcases the importance of user-centered design when creating digital health interventions.

Association between the quality of plant-based diets and risk of frailty. J Cachexia Sarcopenia Muscle 2022; 13:2854-2862. [PMID: 36177985 PMCID: PMC9745455 DOI: 10.1002/jcsm.13077] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 07/11/2022] [Accepted: 08/18/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND The Mediterranean diet and other dietary patterns rich in fruits and vegetables have been linked to lower risk of frailty in older adults. However, not all plant-based diets are necessarily healthful, and no previous study has evaluated the role of the quality of plant-based dietary patterns in frailty risk. Our aim was to assess the association between plant-based diet quality and risk of frailty. METHODS Prospective cohort consisted with 82 234 women aged ≥60 years from the Nurses' Health Study, who were followed from 1990 through 2014. The dates of analysis were April 14 to June 23, 2021. Dietary data were collected every 4 years using a validated semi-quantitative food frequency questionnaire. The plant-based diet quality was assessed with two indices (range 18-90 points): (a) healthful plant-based diet index (hPDI), where healthy plant foods (whole grains, fruits, vegetables, nuts, legumes, vegetable oils and tea/coffee) received positive scores, while less healthy plant foods (fruit juices, sweetened beverages, refined grains, potatoes, and sweets/desserts) and animal foods received reverse scores; and (b) unhealthful plant-based diet index (uPDI) where positive scores were given to less healthy plant foods and reverse scores to healthy plant foods and animal foods. Frailty incidence was assessed every 4 years, being defined as having three or more of the following five criteria from the FRAIL scale: fatigue, low strength, reduced aerobic capacity, having ≥5 illnesses and weight loss ≥5%. Multivariable-adjusted Cox proportional-hazards models were used to estimate hazard ratios (HRs) and their 95% confidence interval (CI). RESULTS We identified 12 910 incident cases of frailty over 1 176 401 person-year follow-up. In the multivariable analysis, the hPDI was inversely associated with the risk of frailty (hazard ratio [HR] for the highest vs. lowest quintile: 0.77, 95% confidence interval: 0.72-0.81; P trend <0.001). In addition, a 10-unit increment in the hPDI was associated with a relative 15% lower risk of frailty. Conversely, a direct association was found between the uPDI and risk of frailty (HR highest vs. lowest quintile: 1.24 [1.17, 1.32], P trend <0.001). These associations were consistent for each frailty criterion, among participants with no frailty criteria at baseline, after excluding participants with diabetes, cancer and cardiovascular disease at baseline, for alternative versions of the plant-based diet indices (PDIs), in subgroup analysis by categories of potential confounders, and in latency analysis. CONCLUSIONS A healthful plant-based diet was associated with lower risk of frailty whereas an unhealthful plant-based diet was associated with higher risk.

Abstract
OBJECTIVE To investigate the associations of a healthful plant-based diet index (hPDI) and an unhealthful plant-based diet index (uPDI) with all-cause and cardiovascular disease (CVD) mortality in Spanish adults. PATIENTS AND METHODS We analyzed data from 11,825 individuals 18 years of age or older, representative of the Spanish population, recruited between 2008 and 2010 and followed-up to 2020. Food consumption was collected at baseline using a validated dietary history, which served to calculate two plant-based diet indices based on 18 major food groups (range, 18-90 points). For (1) hPDI only the consumption of healthy plant foods (whole grains, fruits, vegetables, nuts, legumes, vegetable oils, and tea/coffee) received positive scores; whereas for (2) uPDI, only the consumption of less healthy plant foods (fruit juices, sugar-sweetened beverages, refined grains, potatoes, and sweets/desserts) received positive scores. Multivariable-adjusted Cox models were used to estimate HRs and their 95% CIs. RESULTS After a median follow-up of 10.9 and 9.8 years, 699 all-cause and 157 CVD deaths were ascertained, respectively. Each 10-point increase in hPDI was associated with 14% lower risk of all-cause death (HR, 0.86; 95% CI, 0.74 to 0.99), and 37% lower risk of CVD death (HR, 0.63; 95% CI, 0.46 to 0.85). No significant associations were found for uPDI. CONCLUSION Higher adherence to an hPDI diet, but not to a uPDI, was associated with lower all-cause and CVD mortality. This suggests that the quality of the plant food consumed is paramount to achieve diet-related benefits in mortality. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT02804672.

Dietary Vitamin D Intake, Pain Incidence, and Pain Changes in Older Adults: The Seniors-ENRICA-1 Cohort. Nutrients 2022; 14:nu14183776. [PMID: 36145150 PMCID: PMC9502822 DOI: 10.3390/nu14183776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 09/07/2022] [Accepted: 09/09/2022] [Indexed: 11/30/2022] Open
Abstract
Background: Vitamin D plays a role in bone health, pain signaling, and inflammation. We examined the largely unknown relation of dietary vitamin D intake with pain incidence and pain changes over time in older adults. Methods: Data were taken from the Seniors-ENRICA-1 cohort, which included 950 individuals aged ≥60 years. Habitual vitamin D intake was assessed in 2012 with a validated diet history, and pain both in 2012 and 2017 with a scale ranging from 0 (no pain) to 6 (highest pain), according to its severity, frequency, and number of locations. Analyses on pain incidence and pain changes were performed in the 524 participants free of pain at baseline and the overall sample, respectively. Results: Higher dietary vitamin D intake was associated with lower 5-year pain incidence; the multivariable-adjusted odds ratio (95% confidence interval) was 0.88 (0.79,0.99) for every 1-µg/day increase in vitamin D intake, and 0.49 (0.28,0.88) for the highest (>3.52 µg/day) vs. lowest (<1.85 µg/day) tertile. Dietary vitamin D intake (highest vs. lowest tertile) was also associated with 5-year favorable pain changes: the multivariable-adjusted odds ratio of pain worsening vs. no change/pain improvement was 0.55 (0.36,0.86), and the β coefficient for changes in the pain scale was −0.56 (−1.03,−0.09). Similar results were found for pain severity, frequency, and number of pain locations. Conclusions: In an older adult population, where compliance with vitamin D intake recommendations was very low, a slightly increased dietary intake was associated with lower pain incidence and favorable pain changes over 5 years.

Abstract
Frailty is a geriatric syndrome that leads to increased risk of hospitalization, disability, and death. The effect of plant-based diets defined by the quality of their plant foods is unclear. Our objective is to study the association between two plant-based diet indices and the occurrence of frailty among community-dwelling older adults in Spain. We analyzed data from 1880 individuals aged ≥ 60 years from the Spanish Seniors ENRICA-1 cohort. We used a validated diet history to build two indices: (a) the healthful Plant-based Diet Index (hPDI) where healthy plant foods received positive scores, whereas less-healthy plant foods and animal foods received reverse scores; and (b) the unhealthful Plant-based Diet Index (uPDI), with positive scores to less-healthy plant foods and reverse scores to animal and healthy plant foods. Incident frailty was defined with the Fried phenotype. Study associations were summarized with odds ratios (OR) and 95% confidence intervals (CI) obtained from multivariable logistic models. After 3.3 years of follow-up, 136 incident frailty cases were ascertained. Comparing the highest vs. the lowest tertile of adherence, the OR [95% CI] for frailty was 0.43 (0.25-0.74; p-trend = .003) for the hPDI, and 2.89 (1.73-4.84; p-trend < .001) for the uPDI. Higher consumption of healthy plant foods was inversely associated with frailty (0.39 [0.23-0.66; p-trend < 0.001]); higher consumption of unhealthy plant foods was associated with higher frailty risk (2.40 [1.23-4.71; p-trend = .01]). In older adults, the hPDI was associated with lower risk of frailty, while the opposite was found for the uPDI.

Abstract
OBJECTIVE To assess the association between adherence to a Mediterranean lifestyle and changes in pain, and its characteristics over time in older adults. PATIENTS AND METHODS We analyzed data from 864 and 862 community-dwelling individuals aged 65+ years from the Study on Cardiovascular Health, Nutrition and Frailty in Older Adults in Spain (Seniors-ENRICA) Seniors-ENRICA-1 (2008-2010 to 2012) and Seniors-ENRICA-2 (2015-2017 to 2019) cohorts, with a median follow-up of 2.8 and 2.4 years, respectively. Adherence to a Mediterranean lifestyle was assessed at baseline with the 27-item Mediterranean lifestyle (MEDLIFE) index. Pain changes over time were calculated with a pain scale that assessed the frequency, severity, and the number of pain locations both at baseline and follow-up. Multivariable-adjusted relative risk ratios (RRRs) were obtained using multinomial logistic regression. RESULTS In the pooled cohorts, after a median follow-up of 2.6 years, pain worsened for 697 participants, improved for 734, and did not change for 295. Compared with the lowest category of MEDLIFE adherence, those in the highest category showed an RRR of improvement vs worsening of overall pain of 1.85 (95% CI, 1.28 to 2.67; P-trend<.001). MEDLIFE adherence was also linked to improvement in pain frequency (RRR, 1.98; 95% CI, 1.31 to 3.01; P-trend=.001), pain severity (RRR, 2.00; 95% CI, 1.33 to 3.00; P-trend=.001), and a reduction in the number of pain locations (RRR, 1.68; 95% CI, 1.13 to 2.50; P-trend=.004). Limitations of this study are the use of self-reported lifestyle data. CONCLUSION A Mediterranean lifestyle was associated with improvement of pain characteristics in older adults. Experimental studies should assess the efficacy of an integral lifestyle approach for the management of pain in older adults.

Abstract
There are knowledge gaps regarding healthy lifestyle (HLS) interventions in fire academy settings and also concerning the impacts of the pandemic on training. We enrolled fire recruits from two fire academies (A and B) in New England in early 2019 as the historical control group, and recruits from academies in New England (B) and Florida (C), respectively, during the pandemic as the intervention group. The three academies have similar training environments and curricula. The exposures of interest were a combination of (1) an HLS intervention and (2) impacts of the pandemic on training curricula and environs (i.e. social distancing, masking, reduced class size, etc.). We examined the health/fitness changes throughout training. The follow-up rate was 78%, leaving 92 recruits in the historical control group and 55 in the intervention group. The results show an HLS intervention improved the effects of fire academy training on recruits healthy behaviors (MEDI-lifestyle score, 0.5 ± 1.4 vs. − 0.3 ± 1.7), systolic blood pressure (− 7.2 ± 10.0 vs. 2.9 ± 12.9 mmHg), and mental health (Beck Depression score, − 0.45 ± 1.14 vs. − 0.01 ± 1.05) (all P < 0.05). The associations remained significant after multivariable adjustments. Moreover, a 1-point MEDI-lifestyle increment during academy training is associated with about 2% decrement in blood pressures over time, after multivariable adjustments (P < 0.05). Nonetheless, the impacts of pandemic restrictions on academy procedures compromised physical fitness training, namely in percent body fat, push-ups, and pull-ups.

Abstract
Objectives United States (US) career firefighters represent a working population at high risk for chronic diseases that may benefit from a Mediterranean diet intervention at the public health level. The primary objective of this trial was to assess the effect of a Mediterranean diet nutrition intervention (MDNI) vs. a control group on a modified Mediterranean diet score (mMDS) and Mediterranean diet adherence screener (MEDAS). Methods US career firefighters within the Indianapolis Fire Department (IFD) were enrolled and randomized to either a MDNI (n = 241) or control group (n = 244) and completed follow-up visits at 6 and 12 months. Data collection began in November 2016 and was completed by July 2019. Analysis of covariance was used to estimate age and sex adjusted mMDS and MEDAS mean scores at baseline, 6 months (n = 291), and 12 months (n = 227). Generalized linear regression models were used to estimate mMDS and MEDAS adjusted mean differences between baseline and 12 months (n = 168). Results A total of 485 US career firefighters (95% male with mean age of 47 years (SD = 7.5)) were enrolled in this clinical trial. Age and sex adjusted mMDS mean scores in the intervention group were 23.8 (SE = 0.6) at baseline, 25.5 (0.9) at 6-months, and 26.6 (1.3) at 12 months, whereas the control group scored 24.6 (0.7) at baseline, 24.7 (0.9) at 6 months, and 24.9 (1.2) at 12 months. Participants in the intervention group improved their mMDS at 12 months by 2.1 (1.1), meanwhile the within-group change among controls was −0.4 (1.0). The observed between-group difference was 2.5 (95%CI: 1.0–3.9, p = 0.001). Similarly, age and sex adjusted MEDAS mean scores among the intervention group were 6.3 (0.3) at baseline, 6.1 (0.3) at 6 months, and 6.6 (0.4) at 12-months, whereas controls scored 6.3 (0.3) at baseline, 5.9 (0.3) at 6 months, and 6.0 (0.4) at 12 months. MEDAS within-group differences were 0.3 (0.4) for the intervention group and −0.4 (0.4) among the control group, meanwhile the between-group difference was 0.7 (95%CI: 0.1–1.3, p = 0.02). Conclusions This nutritional intervention trial among US career firefighters showed improved adherence among the MDNI group compared to the control group. These findings suggest the Mediterranean diet is a valid dietary pattern recommendation for this non-Mediterranean working population.

Alcohol consumption patterns and growth differentiation factor 15 among life-time drinkers aged 65+ years in Spain: a cross-sectional study. Addiction 2022; 117:1647-1657. [PMID: 35072312 DOI: 10.1111/add.15809] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Accepted: 01/10/2022] [Indexed: 12/18/2022]
Abstract
AIMS To examine the association of alcohol consumption patterns with growth differentiation factor 15 (GDF-15) in older drinkers, separately among individuals with cardiovascular disease (CVD)/diabetes and those without them, as GDF-15 is a strong biomarker of chronic disease burden. DESIGN Cross-sectional study. SETTING Population-based study in Madrid (Spain). PARTICIPANTS A total of 2051 life-time drinkers aged 65+ years included in the Seniors-ENRICA-2 study in 2015-17. Participants' mean age was 71.4 years and 55.4% were men. MEASUREMENTS According to their average life-time alcohol intake, participants were classified as occasional (≤ 1.43 g/day), low-risk (men: > 1.43-20 g/day; women: > 1.43-10 g/day), moderate-risk (men: > 20-40 g/day; women: > 10-20 g/day) and high-risk drinkers (men: > 40 g/day; women: > 20 g/day; or binge drinkers). We also ascertained wine preference (> 80% of alcohol derived from wine), drinking with meals and adherence to a Mediterranean drinking pattern (MDP) defined as low-risk drinking, wine preference and one of the following: drinking only with meals; higher adherence to the Mediterranean diet; or any of these. FINDINGS In participants without CVD/diabetes, GDF-15 increased by 0.27% [95% confidence interval (CI) = 0.06%, 0.48%] per 1 g/day increment in alcohol among high-risk drinkers, but there was no clear evidence of association in those with lower intakes or in the overall group, or across categories of alcohol consumption status. Conversely, among those with CVD/diabetes, GDF-15 rose by 0.19% (95% CI = 0.05%, 0.33%) per 1 g/day increment in the overall group and GDF-15 was 26.89% (95% CI = 12.93%, 42.58%) higher in high-risk versus low-risk drinkers. Drinking with meals did not appear to be related to GDF-15, but among those without CVD/diabetes, wine preference and adherence to the MDP were associated with lower GDF-15, especially when combined with high adherence to the Mediterranean diet. CONCLUSIONS Among older life-time drinkers in Madrid, Spain, high-risk drinking was positively associated with growth differentiation factor 15 (a biomarker of chronic disease burden). There was inconclusive evidence of a beneficial association for low-risk consumption.

Associations of device-measured sleep, sedentariness and physical activity with growth differentiation factor 15 in older adults. J Cachexia Sarcopenia Muscle 2022; 13:1003-1012. [PMID: 35132822 PMCID: PMC8977966 DOI: 10.1002/jcsm.12924] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 12/14/2021] [Accepted: 01/10/2022] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Growth differentiation factor 15 (GDF-15) is a biomarker for chronic disease burden that might explain the health effects of sedentary behaviours (SBs) and physical activity (PA). We examined associations of device-measured sleep, SB and PA, and time reallocations among them, with GDF-15 in older adults. METHODS We used data from 2245 older adults participating in the Seniors-ENRICA-2 study. Wrist-worn accelerometers were employed to ascertain total time in sleep, SB, light PA (LPA) and moderate-to vigorous PA (MVPA). Associations between these activities and serum GDF-15 levels were analysed using linear regression, including isotemporal substitution models for time reallocations among activities, and adjusted for potential confounders. Analyses were conducted separately in two groups (less active and more active individuals) according to the median total PA time. RESULTS In the less active participants, 30 min/day more of MVPA were related to lower levels of GDF-15 when replacing sleep (fully adjusted mean percentage differences [95% confidence interval] in GDF-15 of -9.2% [-13.2, -5.0]), SB (-9.8% [-13.6, -5.8]) and LPA (-5.8% [-11.1, -0.3]), whereas 30 min/day more of LPA were related to lower GDF-15 when replacing both sleep (-3.6% [-6.1, -1.0]) and SB (-4.2% [-6.7, -1.7]). In the more active participants, 30 min/day more of MVPA were also associated with lower GDF-15 when replacing sleep (-2.9% [-5.3, -0.3]), SB (-2.4% [-4.6, -0.2]) and LPA (-3.5% [-6.6, -0.3]), but no associations were found for more time in LPA. Spending more time in SB was associated with higher GDF-15 levels only among those less active (1.9% [0.9, 2.9] per 30 min/day increment). Sleep time did not appear to be associated with GDF-15. CONCLUSIONS The MVPA was inversely associated with GDF-15, with stronger associations at lower PA volumes. Also, more LPA and less SB time were linked to lower GDF-15 in the less active individuals. This suggests that simply moving more and sitting less may reduce chronic disease burden in older adults.

Abstract
OBJECTIVE To evaluate the opinions of primary health-care providers and patients regarding the use of the Healthy Heart Score 20-year cardiovascular disease risk assessment tool in the clinical setting. METHODS Semi-structured in person or phone interviews among 20 patients with no self-reported cardiovascular disease diagnoses and 20 health-care providers in Central (Columbus) and Southeastern (Athens) regions of Ohio. The researchers independently coded transcribed interviews, discussed codes to resolve discrepancies, and agreed on common themes. RESULTS Participants suggested ways to best utilize and improve the tool, including adding graphics for visual reference of serving size. Patients showed interest in cardiovascular disease primordial prevention and expressed willingness to take the assessment prior to seeing a health-care provider. Health-care providers said that they would recommend the assessment to their patients and would be willing to use the tool in their practice. Health-care providers stated few barriers to using the tool, yet discussed numerous challenges to successful primordial prevention. CONCLUSIONS Our findings support the utilization of the Healthy Heart Score as a cardiovascular disease primordial prevention tool in the clinical setting. Additional research implementing the tool into the clinical setting will provide deeper insight into how the tool can impact behavior change and cardiovascular disease prevention.

Abstract
BACKGROUND Evidence on the comprehensive role of lifestyle in frailty risk is scarce. To assess the association between a lifestyle-based Healthy Heart Score (HHS), which estimates the 20-year risk of cardiovascular disease (CVD), and risk of frailty among older women. METHODS Prospective cohort study in 121,700 nurses from the USA participating at the Nurses' Health Study. This study included 68,416 women aged ≥60 year with a follow-up from 1990 to 2014. The HHS was computed using the gender-specific beta-coefficients of the nine lifestyle factors, including current smoking, high body mass index, low physical activity, lack of moderate alcohol intake and unhealthy diet. Frailty incidence was assessed every 4 years from 1992 to 2014 as having ≥3 of the following five criteria from the FRAIL scale: fatigue, low strength, reduced aerobic capacity, having ≥5 illnesses and weight loss ≥5%. RESULTS During 22 years of follow-up, 11,041 total incident cases of frailty were ascertained. Compared to women in the lowest quintile of the HHS (lowest estimated CVD risk), the multivariable-adjusted hazard ratio of frailty across quintiles was: Q2:1.67 (95% confidence interval 1.53, 1.82); Q3: 2.34 (2.15, 2.53); Q4: 3.54 (3.28, 3.83) and Q5: 5.92 (5.48, 6.38); P-trend > 0.001. Results were consistent for each frailty criterion, among participants with 0 frailty criteria at baseline, when using only baseline exposure or in 6-year-, 10-year- and 14-year-exposure lagged analyses, and after excluding participants with diabetes and CVD at baseline. CONCLUSIONS The HHS, based on a set of modifiable-lifestyle factors, is strongly associated with risk of frailty in older women.

Red meat consumption and risk of frailty in older women. J Cachexia Sarcopenia Muscle 2022; 13:210-219. [PMID: 34755477 PMCID: PMC8818608 DOI: 10.1002/jcsm.12852] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 09/22/2021] [Accepted: 10/04/2021] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Red meat is a nutrient-dense source of protein fundamental for older adults; however, red meat is also high in detrimental components, including saturated fat. It is unclear whether habitual red meat consumption is associated with risk of frailty. This study aimed to examine the prospective association between the consumption of total, unprocessed, and processed red meat and the risk of frailty in older adults. METHODS We analysed data from 85 871 women aged ≥60 participating in the Nurses' Health Study. Consumption of total, unprocessed, and processed red meat was obtained from repeated food frequency questionnaires administered between 1980 and 2010. Frailty was defined as having at least three of the following five criteria from the FRAIL scale: fatigue, low strength, reduced aerobic capacity, having ≥5 chronic illnesses, and unintentional weight loss ≥5%. The occurrence of frailty was assessed every four years from 1992 to 2014. RESULTS During 22 years of follow-up (median follow-up 14 years), we identified 13 279 incident cases of frailty. Women with a higher intake of red meat showed an increased risk of frailty after adjustment for lifestyle factors, medication use, and dietary factors. The relative risk (95% confidence interval) for one serving/day increment in consumption was 1.13 (1.08, 1.18) for total red meat, 1.08 (1.02, 1.15) for unprocessed red meat, and 1.26 (1.15, 1.39) for processed red meat. When each component of the frailty syndrome was individually examined, each of them was positively associated with total red meat consumption, except for the weight loss criterion. Replacing one serving/day of unprocessed red meat with other protein sources was associated with significantly lower risk of frailty; the risk reduction estimates were 22% for fish and 14% for nuts, while for replacement of processed red meat, the percentages were 33% for fish, 26% for nuts, 13% for legumes, and 16% for low-fat dairy. CONCLUSIONS Habitual consumption of unprocessed and processed red meat was associated with a higher risk of frailty. Replacement of red meat by other protein sources might reduce the risk of frailty. These findings are in line with dietary guidelines promoting diets that emphasize plant-based sources of protein.

Healthy lifestyle, metabolomics and incident type 2 diabetes in a population-based cohort from Spain. Int J Behav Nutr Phys Act 2022; 19:8.

Abstract
Background The contribution of metabolomic factors to the association of healthy lifestyle with type 2 diabetes risk is unknown. We assessed the association of a composite measure of lifestyle with plasma metabolite profiles and incident type 2 diabetes, and whether relevant metabolites can explain the prospective association between healthy lifestyle and incident type 2 diabetes. Methods A Healthy Lifestyle Score (HLS) (5-point scale including diet, physical activity, smoking status, alcohol consumption and BMI) was estimated in 1016 Hortega Study participants, who had targeted plasma metabolomic determinations at baseline examination in 2001–2003, and were followed-up to 2015 to ascertain incident type 2 diabetes. Results The HLS was cross-sectionally associated with 32 (out of 49) plasma metabolites (2.5% false discovery rate). In the subset of 830 participants without prevalent type 2 diabetes, the rate ratio (RR) and rate difference (RD) of incident type 2 diabetes (n cases = 51) per one-point increase in HLS was, respectively, 0.69 (95% CI, 0.51, 0.93), and − 8.23 (95% CI, − 16.34, − 0.13)/10,000 person-years. In single-metabolite models, most of the HLS-related metabolites were prospectively associated with incident type 2 diabetes. In probit Bayesian Kernel Machine Regression, these prospective associations were mostly driven by medium HDL particle concentration and phenylpropionate, followed by small LDL particle concentration, which jointly accounted for ~ 50% of the HLS-related decrease in incident type 2 diabetes. Conclusions The HLS showed a strong inverse association with incident type 2 diabetes, which was largely explained by plasma metabolites measured years before the clinical diagnosis.

Abstract
Refining existing dietary assessment methods to reduce measurement error and facilitate the routine evaluation of dietary quality is essential to inform health policy. Notable advancements in technology in the past decade have enhanced the precision and transformation of dietary assessment methods with applications toward both population health and precision nutrition. Within population health, innovative applications of big data including use of automatically collected food purchasing data, quantitative measurement of food environments, and novel, yet simplified dietary quality metrics provide important complementary data to traditional self-report methods. Precision nutrition is similarly advancing with greater use of validated biomarkers for assessing dietary patterns and understanding individual variability in metabolism. Concurrently enhancing our understanding of diet-disease relations at the population health and precision nutrition levels provides tremendous potential to generate evidence needed to advance public health nutrition policy. This commentary highlights the importance of these advances toward progressing the field of dietary assessment and discusses the application of food purchasing data, data analytics, alternative dietary quality metrics, and -omics technology in population and clinical medicine.

Abstract
BACKGROUND Recent evidence has indicated a greater number of protective factors are associated with a greater decreased risk for depression and depressive symptoms compared with individual factors alone. Moreover, adherence to healthy modifiable lifestyle behaviors may lower the risk of depression regardless of underlying genetic risk. OBJECTIVES We longitudinally evaluated the association of the Mediterranean lifestyle (MEDLIFE) with the risk of depression. METHODS We prospectively analyzed data from 15,279 participants (6089 men and 9190 women, mean age 37 y) in the Seguimiento Universidad de Navarra cohort. The MEDLIFE index is composed of 28 items on food consumption, dietary habits, physical activity, rest, social habits, and conviviality, each of which was assigned 0 or 1 point. Final scores ranged from 0 to 28 points and were categorized into quartiles of MEDLIFE adherence. Cox proportional regression models determined the association of total MEDLIFE adherence, each item, and block with incident depression. RESULTS After a mean follow-up of 11.7 y, 912 (6%) incident cases of depression were reported. The mean ± SD final score for MEDLIFE adherence was 11.9 ± 2.7 points. The multivariable model showed that compared with the first quartile, the second and third quartiles of MEDLIFE adherence were significantly associated with a decreased relative risk for incident depression (HR: 0.82; 95% CI: 0.69, 0.96 and HR: 0.74; 95% CI: 0.61, 0.89, respectively). The fourth quartile did not show a statistically significant association with incident depression (HR: 0.89; 95% CI: 0.73, 1.09). CONCLUSIONS MEDLIFE adherence may decrease the risk of depression in a Spanish cohort of university graduates. Given no clear association was observed among the highest MEDLIFE adherence, future studies are warranted to better understand the nature of this association. Evidence on MEDLIFE, beyond the Mediterranean diet, may contribute toward more effective prevention strategies for depression.

Abstract
The A. G. Leventis Foundation International Conference, "Prevention of Alzheimer's Disease and Cognitive Decline with Diet and Lifestyle", was held on May 11-12th, 2022 in Nicosia, Cyprus. This conference examined the role of diet and lifestyle for the prevention and treatment of Alzheimer's Disease and other forms of cognitive decline. Speakers from leading academic institutions presented evidence on healthy dietary patterns, with a particular focus on the traditional Mediterranean diet (MedDiet), in association with cognitive outcomes, mainly cognitive decline, dementia, and Alzheimer's disease, from both observational and interventional studies. Moreover, future directions for the potential use of olive oil, rich in polyphenols, for its therapeutic use as a nutraceutical, as well as nutritional interventions with high-quality dietary patterns (i.e. MedDiet) that support existing primarily observational evidence for the prevention of cognitive decline, as well as challenges in designing rigorous clinical trials are summarized and discussed within the conference proceedings.

Abstract
PURPOSE OF REVIEW Workplaces provide a unique opportunity to deliver health promotion interventions to their workers. This review summarizes evidence from the most recent studies (September 2019 to April 2021) of workplace healthy lifestyle interventions and identifies gaps in the literature and key aspects for successful future workplace lifestyle interventions. RECENT FINDINGS Recent intervention studies have focused on four health domains: (1) multicomponent wellness programs, (2) healthy diet interventions, (3) physical activity interventions, and (4) mental health/sleep interventions. Within each group of studies, there was significant heterogeneity in study length, intervention components, and worker populations. Nonetheless, most studies across all categories showed positive associations between healthy lifestyle interventions and improved worker health. SUMMARY Although recent literature has shown an overall positive trend between healthy lifestyle interventions implemented at the workplace and improvements in markers of health and wellbeing, further research should include longer follow-up periods, more objective measures of wellbeing, evaluation of worker performance, and analogous interventions between studies to identify the most effective interventions to improve worker health and wellness.

Abstract
BACKGROUND Frailty is a geriatric syndrome that entails high risk of hospitalization, disability, and death. While adherence to Mediterranean diet has been associated with lower risk of frailty, the joint effect of diet and lifestyle is uncertain. This study examined the association between a Mediterranean lifestyle (diet, customs, and traditions) and frailty incidence in older adults. METHODS We analyzed data from 1,880 individuals aged ≥ 60 from the prospective Seniors-ENRICA-1 cohort. Adherence to the Mediterranean lifestyle was assessed at baseline with the 27-item MEDLIFE index (higher scores representing better adherence), divided into three blocks: 1) "Mediterranean food consumption", 2) "Mediterranean dietary habits" (practices around meals)" and 3) "Physical activity, rest, social habits and conviviality". Frailty was ascertained as the presence of ≥ 3 of the 5 Fried criteria: a) Exhaustion; b) Muscle weakness; c) Low physical activity; d) Slow walking speed; e) Unintentional weight loss. Main statistical analyses were performed using logistic regression models, adjusting for the main confounders. RESULTS After a 3.3-y follow-up, 136 incident frailty cases were ascertained. Compared with participants in the lowest tertile of the MEDLIFE score, the OR (95% CI) for frailty was 0.88 (0.58-1.34) for the second tertile, and 0.38 (0.21-0.69) for the third tertile (p-trend = 0.003). Blocks 1 and 3 of the MEDLIFE score were independently associated with lower frailty risk. Most items within these blocks showed a tendency to reduced frailty. CONCLUSIONS Higher adherence to a Mediterranean lifestyle was associated with lower risk of frailty.

Abstract
BACKGROUND No prior studies have studied the association between diet and physical resilience, thus our aim was to assess the association between the adherence to the Mediterranean diet and other healthy dietary patterns and physical resilience, assessed empirically as a trajectory through exposure to chronic and acute stressors, in older adults participating in the Seniors-ENRICA (The Study on Nutrition and Cardiovascular Risk in Spain) cohort. METHODS Data were assessed from 1301 individuals aged 60 and older, participating in the ENRICA prospective cohort study and recruited in 2008-2010 and followed up to 2012 (trial registration: NCT02804672). A Mediterranean Diet Adherence Screener score and the Alternate Healthy Eating Index 2010 were derived at baseline from a validated diet history. Health status was assessed at baseline and at the end of follow-up with a 52-item health Deficit Accumulation Index (DAI) including 4 domains (physical and cognitive function, mental health, self-rated health/vitality, and morbidity); higher DAI values indicate worse health. Physical resilience was defined as accumulating fewer health deficits than the expected age-related increase in DAI over follow-up, despite exposure to chronic and acute stressors. RESULTS Over a 3.2-year follow-up, 610 individuals showed physical resilience. In multivariate analyses, the odds ratio (95% confidence interval) of physical resilience for the highest versus lowest tertile (lowest adherence) of the Mediterranean Diet Adherence Screener score was 1.47 (1.10-1.98). The association held for those maintaining or improving the DAI over follow-up (over-resilience): 1.58 (1.10-2.26). Results were consistent in those with unintentional weight loss (2.21 [1.10-4.88]) or hospitalization (2.32 [1.18, 4.57]) as acute stressors. CONCLUSION In older adults, a higher adherence to the Mediterranean diet is associated with a greater likelihood of physical resilience.

Abstract
The traditional Mediterranean diet is considered the world's most evidence-based eating pattern for promoting health and longevity. However, institutional food environments and their busy consumers often sacrifice health benefits for the convenience of faster and cheaper foods that generally are of lower quality and are more processed, and thus, contribute to the current epidemics of obesity and diabetes. Expert consensus has even identified the Mediterranean diet as the easiest to follow among healthy eating patterns. Nonetheless, fewer American families cook at home and many food services have been slow to implement healthier food options compatible with the Mediterranean diet. In September 2019, we convened a group of thought leaders at an exploratory seminar entitled: "Mediterranean Diet: Promotion and Dissemination of Healthy Eating", hosted by the Radcliffe Institute for Advanced Studies at Harvard University. The multidisciplinary faculty discussed best practices for translating traditional Mediterranean lifestyle principles to modern society.

Changes in Health Behaviors, Mental and Physical Health among Older Adults under Severe Lockdown Restrictions during the COVID-19 Pandemic in Spain. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18137067. [PMID: 34281004 PMCID: PMC8297096 DOI: 10.3390/ijerph18137067] [Citation(s) in RCA: 38] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 06/29/2021] [Accepted: 06/30/2021] [Indexed: 12/14/2022]
Abstract
We used data from 3041 participants in four cohorts of community-dwelling individuals aged ≥65 years in Spain collected through a pre-pandemic face-to-face interview and a telephone interview conducted between weeks 7 to 15 after the beginning of the COVID-19 lockdown. On average, the confinement was not associated with a deterioration in lifestyle risk factors (smoking, alcohol intake, diet, or weight), except for a decreased physical activity and increased sedentary time, which reversed with the end of confinement. However, chronic pain worsened, and moderate declines in mental health, that did not seem to reverse after restrictions were lifted, were observed. Males, older adults with greater social isolation or greater feelings of loneliness, those with poorer housing conditions, as well as those with a higher prevalence of chronic morbidities were at increased risk of developing unhealthier lifestyles or mental health declines with confinement. On the other hand, previously having a greater adherence to the Mediterranean diet and doing more physical activity protected older adults from developing unhealthier lifestyles with confinement. If another lockdown were imposed during this or future pandemics, public health programs should specially address the needs of older individuals with male sex, greater social isolation, sub-optimal housing conditions, and chronic morbidities because of their greater vulnerability to the enacted movement restrictions.

Abstract
Abstract
Objectives
The Mediterranean lifestyle (MEDLIFE), as an overall lifestyle pattern rather than individual factors, may be associated with a lower prevalence of metabolic syndrome. The objective was to study the association of a validated MEDLIFE index with metabolic syndrome and its components among a non-Mediterranean working population.
Methods
A cross-sectional analysis was conducted at baseline among 249 US career firefighters in Feeding America's Bravest 2016–2018. The MEDLIFE index consisted of 26 items on food consumption, dietary habits, physical activity, rest, and social interactions that scored 0 or 1 point; scores theoretically could range from 0 to 26 points. Multivariable logistic regression models were used to determine the associations across tertiles of MEDLIFE adherence with metabolic syndrome and its components. Additionally, multivariable linear regressions determined the extent to which each tertile predicted continuous outcomes.
Results
Metabolic syndrome was prevalent among 17.67% of our study population. Participants with higher MEDLIFE adherence (T3: 11–17 points) were 71% less likely to have metabolic syndrome compared to those with lower MEDLIFE adherence (T1: 2–7 points) (OR = 0.29; 95% CI: 0.10 to 0.90, p for trend = 0.04). Furthermore, significant inverse associations were found for T3 versus T1 on abdominal obesity (OR = 0.42; 95% CI: 0.18 to 0.99, p for trend = 0.07) and hypertriglyceridemia (OR = 0.24; 95% CI: 0.09 to 0.63, p for trend = 0.002). Significant inverse associations for continuous outcomes included total-cholesterol, low-density lipoprotein (LDL) cholesterol, and total-c: high-density lipoprotein cholesterol (p for trend < 0.05).
Conclusions
Higher adherence to a traditional Mediterranean lifestyle, measured by a comprehensive MEDLIFE index comprised of lifestyle habits beyond dietary intake and physical activity, may be associated with a lower prevalence of metabolic syndrome and a more favorable cardiometabolic profile in a non-Mediterranean working population. Future studies employing the MEDLIFE index are warranted to further study this hypothesis.
