Lifestyle factors, cardiovascular disease and all-cause mortality in middle-aged and elderly women: a systematic review and meta-analysis

Determination of cardiometabolic risk in pre- and post-menopausal women

OBJECTIVE

The study was designed to determine and compare the cardiometabolic risk in premenopausal and postmenopausal women.

METHODS

Data were collected using cross-sectional and correlational study. In this study, the sociodemographic characteristics, anthropometric measurements, and biochemical parameters of menopausal women were examined.

RESULTS

The average age of menopausal women is higher compared to premenopausal women. Menopausal duration, number of children, daily cigarette consumption, body weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio, systolic and diastolic blood pressure, fasting blood glucose, hemoglobin, AST (aspartate aminotransferase), and Framingham risk score are higher in menopausal women compared to premenopausal women. Conversely, height, HDL (high-density lipoprotein) level, LDL (low-density lipoprotein) level, TSH (thyroid-stimulating hormone), ALT (alanine aminotransferase), HbA1c (glycated hemoglobin), serum albumin, and visceral adiposity index (VAI) values are lower in menopausal women compared to premenopausal women.

CONCLUSION

These findings indicate changes in the metabolic profiles of menopausal women. This study could serve as an important resource for assessing the health status of menopausal women and for implementing appropriate measures.

Trends in Myocardial Infarction Morbidity and Mortality from Ischemic Heart Disease in Middle-Aged Lithuanian Population from 2000 to 2023: Data from Population-Based Kaunas Ischemic Heart Disease Register

Background and Objectives: Over the past decades, various epidemiological analyses have reported a significant decrease in the number of deaths related to cardiovascular diseases (CVDs). Trends in acute myocardial infarction (AMI) morbidity and mortality from ischemic heart disease (IHD) were less studied in Eastern and Central Europe. This study aimed to determine and evaluate changes in AMI morbidity and mortality from IHD among the middle-aged urban Lithuanian population during 2000-2023. Materials and Methods: The data source was the Kaunas ischemic heart disease registry for residents aged 25-64. The diagnosis of AMI was based on the proposed epidemiological criteria used in the WHO MONICA project protocol. Age-standardized morbidity and mortality rates were calculated per 100,000 population. The changes in morbidity and mortality rates were calculated using the Joinpoint regression analysis method, and changes presented as a percentage estimate per year. Results: During 2000-2023, it was observed that age-standardized AMI morbidity significantly changed in the 25-64-year-old male and female population (-1.3%/yr., p = 0.006 and -2.3%/yr., p < 0.001, respectively). In males aged 25-54, a significant decrease in AMI morbidity rates by an average of 2.2%/yr. (p < 0.001) was found, contrary to the males aged 55-64, where morbidity was without substantial changes. We found a significant decrease in AMI morbidity in both age groups (the younger and older) of females, by 2.1%/yr. (p = 0.002) and 2.4%/yr. (p < 0.001), respectively. In the 25-64-year-old male population mortality from IHD significantly decreased (-2.0%/yr., p < 0.001), whereas in females it did not significantly change. Mortality from IHD in males aged 25-54 and 55-64 years significantly decreased by an average of 3.3%/yr. (p = 0.002) and 1.2%/yr., (p = 0.004), respectively. No significant trends in mortality from IHD in both age groups of females over the past 24 years were observed. Conclusions: During the study period, the age-standardized AMI morbidity among Kaunas middle-aged males and females significantly decreased. The age-standardized mortality from IHD decreased significantly among Kaunas middle-aged males, but there were no significant changes among females.

The interplay between body mass index, motivation for food consumption, and noncommunicable diseases in the European population: A cross-sectional study

INTRODUCTION

Consuming unhealthy foods in emotional states can increase body mass index (BMI), contribute to becoming overweight, and lead to the development of chronic diseases. This study aims to investigate the associations between BMI, emotional motivation for food consumption, and health outcomes.

MATERIALS AND METHODS

"The Motivations for Food Choices" (EATMOT) questionnaire was used to assess the emotional components of food consumption in 9,036 individuals from 12 European countries. The multivariate analysis included linear and logistic regression to examine associations between variables.

RESULTS

Regression models confirmed associations between BMI, emotional motivation for food consumption (β = 0.13; p < 0.001), obesity (β = 0.35; p < 0.001), diabetes mellitus, and hypertension (β = 0.04; p < 0.001 for both). Using food as a coping mechanism for stress contributed to an increase in BMI [OR = 1.31 (95% CI 1.14-1.51); p < 0.001]. Emotional consolation was associated with a higher likelihood of an increased BMI [OR = 1.22 (95% CI 1.03-1.44); p = 0.020] and obesity [OR = 1.47 (95% CI 1.06-2.06); p = 0.022]. Participants with obesity had a greater likelihood of developing noncommunicable diseases, such as cardiovascular diseases [OR = 2.18 (95% CI 1.45-3.28); p < 0.001], diabetes mellitus [OR = 2.02 (95% CI 1.31-3.12); p = 0.001], hypercholesterolemia [OR = 1.62 (95% CI 1.13-2.32); p = 0.009], hypertension [OR = 1.85 (95% CI 1.36-2.52); p < 0.001], and gastric disorders [OR = 1.81 (95% CI 1.16-2.85); p = 0.010].

CONCLUSION

These results underscore the need for targeted public health interventions that address emotional eating behaviors and promote healthier coping strategies to mitigate the risk of obesity and related health complications.

Dietary patterns derived using reduced rank regression in postmenopausal women and risk of mortality: A population-based study

OBJECTIVES

The menopause transition increases the risk of chronic conditions in women. Given the crucial role of diet in health, we identified dietary patterns that explain variations in factors related to major health concerns in postmenopausal women. Also, we explored their association with all-cause and cardiovascular mortality.

STUDY DESIGN

This study was conducted on 1814 postmenopausal women from the population-based Rotterdam Study.

MAIN OUTCOME MEASURES

Dietary patterns were identified using reduced rank regression. Response variables included bone mineral density, body composition parameters, lipid profile markers, insulin resistance, systolic blood pressure, cognitive function, depression, and sleep quality. The associations with risk of mortality were assessed using Cox proportional hazard models.

RESULTS

The first dietary pattern, characterized by higher intake of vegetables, whole grains, legumes, nuts, coffee, tea, alcoholic beverages, and cheese, explained 2.95 % of the variation in responses, accounted for 12.11 % of the variation in general cognitive function captured by G-factor, 5.62 % in systolic blood pressure, and 4.13 % in bone mineral density, and was correlated with less adiposity, lower blood pressure, lipid markers, and insulin resistance. The second dietary pattern, characterized by higher intakes of processed meat, unprocessed red meat, poultry, eggs, and coffee, and lower intakes of sweets and tea, explained 1.54 % of the variation in responses, accounted for 5.45 % of variation in fat mass percentage, 3.47 % in lean mass index, and 3.29 % in bone mineral density, and was correlated with higher adiposity, insulin resistance, and lipid markers. No associations with mortality risk were identified after adjusting for confounders such as demographics, socioeconomic status, lifestyle, disease history, and medication use.

CONCLUSIONS

We identified dietary patterns explaining a range of variation in health factors related to postmenopausal health. While these dietary patterns explained a large variation in some of the individual factors, their combined explained variation across multiple risk factors simultaneously was limited and no significant association with mortality risk was observed. This study provides a foundation for future research aimed at identifying optimal dietary patterns, integrating diverse health aspects, to improve health in postmenopausal populations.

Nonlinear relationships between the triglyceride glucose-body mass index and cardiovascular disease in middle-aged and elderly women from NHANES (1999-2018)

This study aims to investigate the relationship between the triglyceride-glucose body mass index (TyG-BMI) and cardiovascular disease (CVD) among middle-aged and elderly women, using data from the National Health and Nutrition Examination Survey (NHANES) spanning from 1999 to 2018. TyG-BMI was calculated as Ln [fasting triglycerides (mg/dL) × fasting glucose (mg/dL)/2] × BMI. After applying the sampling weights from NHANES, the study sample of 6,343 participants is representative of approximately 59,174,898 American women. We categorized TyG-BMI into quartiles, using Q3 as the reference group. In the crude model, Q4 exhibited a 40% increased odds of CVD (odds ratio [OR] = 1.40, 95% confidence interval [CI] 1.09-1.79, P = 0.009). In the fully adjusted model, the increased odds of CVD for Q4 relative to Q3 was 39% (OR = 1.39, 95% CI 1.06-1.82, P = 0.019). Further analysis using restricted cubic splines (RCS) and threshold effect analysis confirmed a nonlinear relationship between them. Below a TyG-BMI threshold of 260, there was no significant association with CVD odds. However, above 260, each 10-unit increase in TyG-BMI was associated with a 2.4% increase in CVD odds in this demographic. Sensitivity analyses confirmed the stability of the results.

Non-communicable disease (NCD) burden and their contributing factors among women

Non-communicable diseases (NCDs) account for 74% of worldwide deaths annually. A search in 'Google Scholar' and 'PubMed' showed a total of 224,854 articles and after adjusting for time period and relevance, 43 were selected. Cancer, cardiovascular diseases (CVDs), respiratory diseases and diabetes were the most prevalent NCDs among females. Cancer-related deaths in females are expected to rise to 5.5 million by 2030, and hormonal factors, smoking, alcohol consumption and obesity are the biggest contributors. CVD deaths were 8.94 million in 2019, and poor pregnancy outcomes and fertility issues increase females' CVD risk. Respiratory diseases affect 6.16% young females and smoking, a high BMI, and high processed food intake, increase the risk. Diabetes effects 9% women and hormonal factors increase the risk, whereas psychosocial factors may impact diabetes prevention and treatment. The female NCD burden is increasing and there is a need for multi-interventional approach to effectively manage these diseases.

How are socioeconomic status, social support, and health history associated with unhealthy lifestyle behaviours in middle-aged adults? Results of the Swedish CArdioPulmonary bioImage Study (SCAPIS) COHORT

BACKGROUND

Unhealthy lifestyle behaviours, including unhealthy alcohol consumption, physical inactivity, smoking, and nonadherence to dietary recommendations, are major contributors to non-communicable diseases and mortality. While adopting healthy behaviours can reduce these risks in middle-aged adults, research is limited. Therefore, the aim of this study was to assess the distribution of unhealthy lifestyle behaviours in middle-aged adults and their associations with socioeconomic factors, social support, and history of disease.

METHOD

This was a cross-sectional study of the Swedish CArdioPulmonary bioImage Study (SCAPIS) cohort (2013-2018) at six Swedish university hospitals. Multilevel regression models were estimated using Bayesian inference with priors shrinking covariate estimates towards the null.

RESULTS

In total, 59 909 participants, aged 50-64 years old were invited to SCAPIS, of which 30 154 (50.3%) decided to participate. The mean age of participants was 58 (SD = 4) years old, and 51% were women (n = 15 508). Men had higher unhealthy alcohol consumption and were less adherent to dietary recommendations compared to women. Older participants were more physically inactive compared to younger participants. Low education and financial difficulties were associated with smoking, physical inactivity, and poor diet adherence. Financial difficulties were also associated with unhealthy alcohol consumption. Having more people to turn to in difficulties was associated with lower alcohol consumption. Lack of appreciation and comfort support was associated with smoking and poor diet adherence. Diabetes was associated with lower alcohol consumption. Diabetes and lung diseases were associated with smoking and inactivity.

CONCLUSIONS

Middle-aged adults with lower socioeconomic status, less quality social support, and a history of disease were more likely to engage in unhealthy behaviours. This study helps to identify groups of middle-aged adults who may require additional attention when it comes to prioritizing the development of preventive measures.

Body Shapes of Multiple Anthropometric Traits and All-cause and Cause-specific Mortality in the UK Biobank

BACKGROUND

Individual traditional anthropometric measures such as body mass index and waist circumference may not fully capture the relation of adiposity to mortality. Investigating multitrait body shapes could overcome this limitation, deepening insights into adiposity and mortality.

METHODS

Using UK Biobank data from 462,301 adults (40-69 years at baseline: 2006-2010), we derived four body shapes from principal component analysis on body mass index, height, weight, waist and hip circumference, and waist-to-hip ratio. We then used multivariable-adjusted Cox proportional hazard models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between body shapes and mortality for principal component scores of +1 and -1.

RESULTS

During 6,114,399 person-years of follow-up, 28,807 deaths occurred. A generally obese body shape exhibited a U-shaped mortality association. A tall and centrally obese body shape showed increased mortality risk in a dose-response manner (comparing a score of +1 and 0: HR = 1.16, 95% CI = 1.14, 1.18). Conversely, tall and lean or athletic body shapes displayed no increased mortality risks when comparing a score of +1 and 0, with positive relations for the comparison between a score of -1 and 0 in these shapes (short and stout shape: HR = 1.12, 95% CI = 1.10, 1.14; nonathletic shape: HR = 1.15, 95% CI = 1.13, 1.17).

CONCLUSION

Four distinct body shapes, reflecting heterogeneous expressions of obesity, were differentially associated with all-cause and cause-specific mortality. Multitrait body shapes may refine our insights into the associations between different adiposity subtypes and mortality.

Relationship between lifestyle factors and cardiovascular disease prevalence in Somaliland: A supervised machine learning approach using data from Hargeisa Group Hospital, 2024

BACKGROUND

Cardiovascular diseases (CVDs) are leading contributors to global morbidity and mortality, with low- and middle-income countries experiencing disproportionately high burdens. In Somaliland, urbanization and lifestyle transitions have increased the prevalence of CVDs, necessitating an in-depth exploration of associated risk factors.

OBJECTIVE

This study investigated the relationship between lifestyle factors and CVD prevalence among adult patients in Somaliland using data from the Hargeisa Group Hospital in 2024.

METHODS

A cross-sectional design was employed, enrolling 411 adults aged ≥ 18 years. Data were collected through structured questionnaires and analyzed using traditional statistical methods and seven supervised machine learning models: Logistic Regression, Random Forest, Support Vector Machine (SVM), Probit Regression, KNN and Decision Tree. The study assessed associations between sociodemographic variables, lifestyle factors, and CVD prevalence while evaluating the predictive model performance.

RESULTS

Age and smoking were the most significant predictors of CVD prevalence across all models, with individuals aged ≥ 60 years exhibiting the highest risk. Urban residence was associated with lower CVD prevalence, while behaviors such as khat chewing and physical inactivity increased the risk. Machine learning models, notably SVM, demonstrated robust predictive performance, achieving an accuracy of 63.4 % and an AUC of 67.1 %.

CONCLUSION

Lifestyle factors, particularly smoking, khat chewing, and dietary habits, are critical drivers of the CVD prevalence in Somaliland. These findings underscore the need for targeted public health interventions focusing on smoking cessation, dietary improvements, and culturally sensitive awareness campaigns. Machine learning techniques offer valuable tools for enhancing the predictive accuracy and guiding tailored health strategies.

Relation of Reproductive Lifespan with Obesity in Chinese Women: Results from a Large Representative Nationwide Population

Background: Research on the association between age at menarche and menopause, reproductive lifespan, and the risk of obesity in China is unclear and requires further clarification. Materials and Methods: Data were obtained from the China Hypertension Survey, a cross-sectional study using a stratified multistage random sampling method, conducted from October 2012 to December 2016, with a total of 187,162 women included in the analysis. Logistic regression models and restricted cubic spines were used to estimate the relationship between obesity and age at menarche, age at menopause, and reproductive lifespan. Results: The mean (standard deviation) age at menarche and menopause, and reproductive lifespan were 15.5 (1.8), 48.7 (3.5), and 33.2 (3.9) years, respectively. Age at menarche was negatively related to the risk of obesity (odds ratio [OR]: 0.968; 95% confidence interval [CI]: 0.961-0.975). There was a positive association between age at menopause and the risk of obesity in postmenopausal women (OR: 1.019; 95% CI: 1.014-1.023). Reproductive lifespan was positively related to obesity (OR: 1.020; 95% CI: 1.017-1.025). The restricted cubic spines showed the association between age at menarche, age at menopause, reproductive lifespan, and obesity was nonlinear when fully adjusted. Conclusions: Based on the large nationally representative sample, Chinese women with earlier age at menarche, later age at menopause, and longer reproductive lifespan have a higher risk of obesity.

Ten-year atherosclerotic cardiovascular disease risk score in post-menopausal women with low bone mineral density

BACKGROUND

Reports on the association between cardiovascular disease (CVD) risk and bone mineral density (BMD) remain inconsistent and hence more population-based studies on this subject are needed.

AIMS

This cross-sectional study aimed to evaluate the association between bone mineral density (BMD) at the lumbar spine (L1-L4) and femoral neck (right and left) with 10-year atherosclerotic cardiovascular disease (ASCVD) risk scores in Saudi postmenopausal women.

METHODS

A cohort of 1,450 postmenopausal women with risk factors for bone loss were analyzed using the data from the Chair for Biomarkers of Chronic Diseases (CBCD) Osteoporosis database. BMD at the lumbar spine and femoral neck was assessed using dual-energy X-ray absorptiometry (DXA). Anthropometric and biochemical parameters, including fasting glucose and lipid profiles, were measured. ASCVD risk scores were calculated using the ASCVD Risk Estimator Plus tool. BMD tertiles were analyzed for their association with ASCVD risk.

RESULTS

Women with osteoporosis had significantly lower BMI, waist and hip circumferences, and metabolic dysfunction markers compared to those with normal BMD. Significant negative correlations were observed between ASCVD risk scores and BMD at femoral neck sites in women with osteopenia and osteoporosis. Multivariate logistic regression indicated that women in the lowest BMD tertiles had significantly higher odds of intermediate to high ASCVD risk scores, with adjusted odds ratios of 1.90 for the lumbar spine, 2.19 for the right femoral neck, and 2.04 for the left femoral neck.

CONCLUSIONS

The study identified significant associations between lower BMD at the lumbar spine and femoral neck sites and elevated 10-year ASCVD risk scores in postmenopausal women, particularly among those with osteopenia and osteoporosis. These findings demonstrate the importance of assessing cardiovascular risk in women with low BMD to enable early prevention and management strategies.

Age of menopause, healthy lifestyle and cardiovascular disease in women: a prospective cohort study

BACKGROUND

Menopause is a timely opportunity to screen for cardiovascular disease (CVD) and intervene with healthier lifestyles. We investigated the association between premature/early menopause and the likelihood of CVD and whether a healthy lifestyle is associated with a lower likelihood of CVD in menopausal woman.

METHODS

The Sax Institute's 45 and Up Study prospectively recruited participants aged ≥45 years (n=267 357) between 2005 and 2009 (New South Wales, Australia). Our study included women without prior CVD and reporting menopausal age at baseline. Primary outcome was new-onset CVD (self-reported heart disease/stroke) based on survey data at Wave 2 (2012-2015) and/or Wave 3 (2018-2020). Logistic regression models assessed the associations of premature (age <40 years) and early (age 40-44 years) menopause with CVD, compared with menopause between 50 and 52 years, adjusting for sociodemographic and clinical variables. Healthy lifestyle adherence was assessed using a score of five factors: smoking, physical activity, sitting, sleep and diet.

RESULTS

We included 46 238 women (mean age 62.1±8.2 years), with 5416 (11.7%) cases of CVD over 15-year follow-up. After adjustment, the odds of CVD was higher in women with premature menopause (OR 1.36, 95% CIs 1.17 to 1.59; p<0.0001) and early menopause (OR 1.15, 95% CI 1.03 to 1.28; p=0.013) compared with menopause between 50 and 52 years. Among all women, high (score 9-10) versus low (score 0-5) healthy lifestyle adherence led to 23% lower odds of CVD (OR 0.77, 95% CI 0.68 to 0.86; p<0.0001), and in women with premature menopause, led to 52% lower odds of CVD (OR 0.48, 95% CI 0.30 to 0.77, p=0.0022). Lifestyle effect did not significantly differ between menopause categories (interaction, p=0.71).

CONCLUSION

Women with premature/early menopause are at higher likelihood for CVD. Lifestyle modification is associated with consistent reduction of the likelihood of CVD in women and should be encouraged across the life course.

Dyadic Associations Between Self-Perceptions of Aging and Health Behaviors Among Middle-Aged and Older Couples

BACKGROUND AND OBJECTIVES

Research and theory suggest that older adults' self-perceptions of aging (SPA) are associated with their health behavior engagement. Likewise, romantic partners often play a key role in shaping each other's health behaviors. This study aims to explore the longitudinal dyadic associations between SPA and health behaviors among couples in midlife and older adulthood.

RESEARCH DESIGN AND METHODS

Data were drawn from 3,330 couples ages 50-96 (Mmen = 67.22 [9.43]; Mwomen = 65.42 [8.96]) from the Health and Retirement Study, using pooled samples from 2010/2012 to 2012/2014. We estimated actor-partner interdependence models with moderation to assess whether and to what extent a partner's SPA moderated the links between positive and negative SPA and engagement in preventive and risky health behaviors two years later.

RESULTS

Women's SPA moderated the association between men's SPA and men's risky health behaviors only when women reported extreme levels of negative or positive SPA. In contrast, men's SPA did not moderate the associations between women's SPA and women's health behaviors.

DISCUSSION AND IMPLICATIONS

This study's findings emphasize that links between SPA and health behaviors operate within the broader social environment and in the context of romantic relationships. The results highlight how couples' perceptions of aging relate to their own and their partners' health behaviors. This work contributes to the literature on the gendered and social nature of health behaviors and has implications for designing interventions targeting SPA.

The effect of probiotic administration on the severity of menopausal symptoms and mental health of postmenopausal women: a triple-blind randomized controlled trial in the West of Iran

OBJECTIVE

Menopausal symptoms are a reproductive health issue for women. Some studies have suggested that the use of probiotics may alleviate the severity of menopausal symptoms and mental health status. This study aimed to evaluate the effect of probiotic administration on the severity of menopausal symptoms and improve mental health in postmenopausal women in Hamadan, Western Iran.

METHODS

A triple-blind randomized controlled trial was conducted from February 20, 2023, to August 23, 2023, at the Comprehensive Health Service Centers in Hamadan City, Western Iran. Participants were randomized to intervention and control groups. The participants in the intervention group were administered probiotic supplements in 200 mg daily capsules for 6 weeks, and those in the control group received 200 mg daily capsules containing starch powder for 6 weeks. The primary outcomes were measured using the Menopausal Rating Scale and Depression Anxiety and Stress Scale questionnaires at baseline, week 3, and week 6.

RESULTS

A total of 84 women took part in the study, with 42 individuals assigned to each of the intervention and control groups, respectively. The findings indicated no significant differences in baseline characteristics between the study groups ( P > 0.05). The results indicated that the study outcomes changed differently over time between the two groups. The participants in the intervention group exhibited greater improvements in depressive symptoms, anxiety, and stress symptoms, as well as in physical, psychological, and urogenital symptoms at both week 3 and week 6, compared with the control group ( P < 0.05).

CONCLUSIONS

This study provides evidence regarding potential treatment effects of probiotics consumption in alleviating physical and mental symptoms related to menopause. Further multicenter and large-scale clinical trials with longer follow-up are recommended.

Association between lifestyle risk factors and mortality in the Mexico City prospective study

Unhealthy lifestyles risk factors, such as smoking, alcohol consumption, physical inactivity, poor diet, and obesity, have been associated with a higher risk of all-cause and cause-specific mortality. However, composite score of these unhealthy behaviours has not been considered, particularly in Latin American populations. Herein, we examined the association of lifestyle risk factors score with all-cause and cause-specific mortality in Mexican adults. A total of 159,517 adults from the Mexico City Prospective Study (MCPS) were included. Data on sociodemographic, lifestyle risk factors and medical histories was collected through a self-reported baseline questionnaire in a census-style door-to-door interviews. Lifestyle risk factors assessment was based on five modifiable lifestyle risk factors and their respective cut-off points according to current health recommendations, including obesity, physical inactivity, tobacco, alcohol consumption and fruits and vegetables intake. Multivariable Cox regression models were used to estimate the associations of lifestyle risk factor score (ranging from 0 to 5) with all-cause and cause-specific mortality (cardiovascular disease, renal or hepatobiliary diseases, diabetes, respiratory diseases, cancer and all-cause mortality). We excluded the first 2, 5, 10, and 15 years of follow-up to account for reverse causation bias. We found a high prevalence (77%) of Mexican adults, with two or more lifestyle risk factors. Hazard ratio for respiratory diseases and renal or hepatobiliary diseases were 1.86 (95%CI: 1.45-2.39) and 2.00 (95%CI: 1.60-2.52) comparing participants with 4-5 lifestyle risk factors vs. those with none. For all-cause mortality, participants with 4-5 lifestyle risk factors had a 49% (HR: 1.49; 95%CI: 1.03-2.16) higher risk as compared to participants with none. The magnitude of the associations increased as the exclusion of follow-up time increased after 2, 5, 10 and 15 years. There was a positive association between the number of lifestyle risk factors and all-cause and cause-specific mortality, showing the highest rate of respiratory, renal or hepatobiliary and all-cause mortality among participants with 4-5 lifestyle risk factors. After accounting for reverse causation, associations were stronger.

Sex modifies association between dietary sodium intake and cardiovascular disease mortality among US adult with hypertension: a national population-based cohort

Objectives

The objective of this study was to examine the relationship between dietary sodium intake and cardiovascular disease (CVD) mortality in hypertensive American adults.

Methods

A prospective cohort study was conducted to examine the association between dietary sodium intake, as estimated by a single 24-h dietary recall from the National Health and Nutrition Examination Survey (2003-2012), and mortality data obtained from the National Death Index.

Results

This study included 12,236 adults with hypertension, with 837 CVD-related deaths identified over a median follow-up period of 10.3 years. A nonlinear association between dietary sodium intake and CVD mortality was observed. The inflection point of the curve occurred at a sodium intake level of 2.07 g/day. Below this threshold, higher sodium intake was associated with a reduced risk of CVD mortality, though the association was not statistically significant after full adjustment (aHR: 0.78, 95% CI: 0.58-1.05). In contrast, sodium intake above 2.07 g/day was significantly associated with an increased risk of CVD mortality (aHR: 1.12, 95% CI: 1.02-1.23). The log-likelihood ratio test yielded a P-value of 0.04. This J-shaped association was observed exclusively in females, not males. Among females, the adjusted hazard ratios (95% CI) were 0.65 (0.42, 0.99) below and 1.29 (1.11, 1.53) above the inflection point (P for log-likelihood ratio test = 0.009).

Conclusions

In American adults with hypertension, dietary sodium intake exceeding 2.07 g/day was significantly associated with an increased risk of CVD mortality, while intake below this threshold was not significantly linked to mortality risk. Additionally, a sex-specific effect of dietary sodium intake on CVD mortality was observed, showing a J-shaped relationship exclusively in females, with no such association found in males.

Combined prediagnostic lifestyle factors and survival of breast, colorectal and lung cancer in the Norwegian Women and Cancer (NOWAC) study: a prospective cohort study

BACKGROUND

With improvements in cancer treatment and early detection, the number of people living with cancer is increasing.

OBJECTIVE

This study aimed to investigate the association between combined prediagnostic lifestyle factors, assessed by a Healthy Lifestyle Index (HLI) score, and mortality among women diagnosed with breast cancer (BC), colorectal cancer (CRC) and lung cancer (LC).

DESIGN

Prospective cohort.

SETTING

Women residing in Norway, general population.

PARTICIPANTS

Our analysis included 5032, 2468 and 1594 women from the Norwegian Women and Cancer study diagnosed with BC, CRC and LC, respectively, who responded to a questionnaire between 1996 and 2014.

EXPOSURE MEASURES

HLI score measured prior to cancer diagnosis. The HLI combines physical activity level, body mass index, smoking behaviour, alcohol consumption and dietary habits.

OUTCOME MEASURES

We estimated HRs and 95% CIs using Cox proportional hazard models for all-cause and site-specific cancer mortality.

RESULTS

After median follow-up times of 9.8, 7.1 and 5.9 years for BC, CRC and LC cases, respectively, there were 912, 902 and 1094 all-cause deaths; and 509 BC deaths, 679 CRC deaths and 961 LC deaths. For women diagnosed with BC, a 1-point HLI score increment was associated with a 6% lower all-cause mortality rate (HR: 0.94, 95% CI: 0.92 to 0.97). The data were compatible with no association for the estimated 3% lower BC mortality rate (HR: 0.97, 95% CI: 0.94 to 1.00) among women diagnosed with BC, and for the estimated 3% lower all-cause (HR: 0.97, 95% CI: 0.95 to 1.00) and 2% lower CRC mortality rates (HR: 0.98, 95% CI: 0.95 to 1.01) among women diagnosed with CRC. For women diagnosed with LC, prediagnostic HLI score was not associated with all-cause (HR: 1.00, 95% CI: 0.98 to 1.02) or LC mortality rates (HR: 1.00, 95% CI: 0.98 to 1.03).

CONCLUSIONS

We observed that a higher HLI score measured before cancer diagnosis was associated with lower all-cause and, possibly, lower BC mortality among Norwegian women diagnosed with BC; and a possible lower all-cause and CRC mortality among those diagnosed with CRC. Smoking was likely responsible for the observed associations.

Identification of metabolic syndrome using lipid accumulation product and cardiometabolic index based on NHANES data from 2005 to 2018

BACKGROUND

Numerous studies indicate that visceral adipose tissue (VAT) significantly contribute to metabolic syndrome (MetS) development. This study aims to assess the distinguishing value of novel obesity markers, specifically lipid accumulation products (LAP) and cardiometabolic index (CMI), in relation to MetS. Considering the gender disparity in MetS prevalence, it is essential to explore whether LAP and CMI exhibit differential distinguishing capabilities by gender.

METHOD

The investigation included a total of 11,687 qualified individuals who participated in the NHANES survey spanning a 14-year period from 2005 to 2018. Biochemical analysis of blood and body measurements were utilized to determine LAP and CMI values for each participant. Inclusion of gender as a variable was a key factor in the examination of all data. Restricted cube plots (RCS) were utilized to analyze the strength of the relationship between LAP, CMI, and MetS. The study delved into potential connections between LAP and CMI with MetS, all-cause and cardiovascular mortality using various statistical models such as multivariate logistic regression and Cox regression.

RESULTS

The findings revealed a significant nonlinear association between CMI, LAP, and MetS (P-non-linear < 0.001), irrespective of gender, with all models exhibiting a J-shaped trend. The multivariable logistic regression analysis considered both LAP and CMI as continuous variables or tertiles, revealing significant associations with MetS in male, female, and general populations (All the P < 0.001). Although males displayed a higher risk of MetS, no gender differences were observed in the area under the curve (AUC) values of LAP and CMI for distinguishing (P > 0.005) MetS. Impressively, LAP and CMI were identified as the primary predictors of MetS in both genders from AUC (P < 0.005). More specifically, the cutoff points for distinguishing MetS in females were LAP = 49.87 or CMI = 0.56, while for males, they were LAP = 52.76 or CMI = 0.70. Additionally, the Cox regression analysis revealed that LAP and CMI were correlated with all-cause mortality in both general population and females (P < 0.005), but not in males.

CONCLUSION

In comparison to other measures of obesity, LAP and CMI demonstrated superior diagnostic accuracy for MetS in both males and females. Additionally, LAP and CMI were found to be predictive of all-cause mortality in both general population and females. These markers are cost-effective, easily accessible, and widely applicable for the early identification and screening of MetS in clinical settings.

Economic burden of cardiovascular diseases among elderly patients in Iran: a case from a developing country

BACKGROUND

Cardiovascular diseases (CVDs) are the leading cause of mortality and morbidity worldwide, particularly among the aging population. This study aims to evaluate the economic burden of CVDs among Iranians aged 60 years and older.

METHODS

A cost-of-illness study was conducted using a prevalence-based approach from a societal perspective. Cost analysis employed the bottom-up micro-costing method to assess direct medical and non-medical costs, while indirect costs were calculated using the human capital approach. Data were sourced from medical records of individuals aged 60 and older with CVDs registered in the hospital information systems of public and private hospitals in southeastern Iran. Additionally, structured face-to-face interviews were conducted with 160 caregivers or relatives serving as companions of elderly patients, using a structured questionnaire to gather data on healthcare utilization. Sensitivity analyses were performed, along with projections of the future economic burden of CVDs.

RESULTS

The annual total cost of CVDs among people aged 60 years and above in Iran was estimated at US$ 1,885,091,171.7 (about 1.88 billion), equivalent to 1.27% of the Iran's GDP in 2021. Direct medical costs accounted for 90.62% of the total, with 54.72% attributed to ambulatory care. The average cost of CVDs per patient was US$ 446.2. The results of two-way sensitivity analysis provided an estimated cost range between US$ 1.2 billion and US$ 2.7 billion. By 2030, the total cost of CVDs is projected to reach US$ 21 billion.

CONCLUSIONS

The elderly population with CVDs imposes a growing economic burden on Iran's healthcare system and society. This underscores the urgent need for effective and cost-effective interventions to prevent and manage CVDs in Iran.

Global prevalence of depression, anxiety, and stress in the elderly population: a systematic review and meta-analysis

BACKGROUND

Several preliminary studies have been conducted in the field of the prevalence of depression, anxiety, and stress in the elderly population. These studies have examined the prevalence in limited geographic areas with small sample sizes. Also, there are many limitations in the meta-analysis studies. The objective of the present study was to synthesize the global prevalence statistics of depression, anxiety, and stress in the elderly population through a systematic review and meta-analysis.

METHODS

The present systematic review included retrieval of primary studies from the oldest relevant study up to 2023. To find the relevant studies, international databases such as Scopus, Embase, PubMed, and Web of Science (WoS) were systematically searched. Also, a manual search was performed through the Google Scholar search engine and a review of the sources of related articles. The qualitative assessment of the studies was conducted using the Joanna Briggs Institute (JBI) checklist. Due to a high heterogeneity among the study results, a Random Effects model was chosen.

RESULTS

A total of 42 articles on depression, 47 articles on anxiety and 13 articles on stress were included in the meta-analysis. The overall estimates for prevalence based on a random-effects model were as follows: depression, 19.2% (95% CI: 13.0 - 27.5%); anxiety, 16.5% (95% CI: 11.1 - 22.8%); and stress, 13.9% (95% CI: 5.5 - 30.9%). The highest prevalence of depression and anxiety was recorded in Africa. The prevalence of depression was higher in nursing homes, and stress was more prevalent in individuals with COVID-19 compared to other populations.

CONCLUSION

The findings revealed a high prevalence of depression, anxiety, and stress in the elderly population. Therefore, it is recommended that healthcare professionals and policymakers pay more attention to the prevention and management of these disorders in the elderly population.

Bayesian spatial-temporal analysis and determinants of cardiovascular diseases in Tanzania mainland

BACKGROUND

Cardiovascular Diseases (CVDs) are health-threatening conditions that account for high mortality in the world. Approximately 23.6 million deaths due to CVD is expected in the year 2030 worldwide. The CVD burden is more severe in developing countries, including Tanzania.

OBJECTIVES

This study analyzed the spatial-temporal trends and determinants of cardiovascular diseases in Tanzania from 2010 to 2019.

METHODS

Individual data were extracted from Jakaya Kikwete Cardiac Institute (JKCI), Mbeya Zonal Referral Hospital (MZRH), Kilimanjaro Christian Medical Centre (KCMC) and Bugando hospitals and the geographical data from TMA. The model containing spatial and temporal components was analyzed using the Bayesian hierarchical method implemented using Integrated Nested Laplace Approximation (INLA).

RESULTS

The results found that the incidence of CVD increased from 2010 to 2014 and decreased from 2015 to 2019. The southern highlands, lake, central and coastal zones were more likely to have CVD problems than others. It was also revealed that people aged 60-64 years OR = 1.49, females OR = 1.51, smokers OR = 1.76, alcohol drinkers OR = 1.48, and overweight OR = 1.89 were more likely to have CVD problems. Additionally, a 1oC increase in the average annual air maximum temperature was related to a 14% risk of developing CVD problems. The study revealed that the model, which included spatial and temporal random effects, was the best-predicting model.

CONCLUSION

The study shows a decreased CVD incidence rate from 2015 to 2019. The CVD incidences occurred more in Tanzania's coastal and lake areas between 2010 and 2019. The demographic, lifestyle and geographical risk factors were significantly associated with the CVD.

Changes in 10-Year Predicted Cardiovascular Disease Risk for a Multiethnic Semirural Population in South East Asia: Prospective Study

BACKGROUND

Cardiovascular disease (CVD) risk factors tend to cluster and interact multiplicatively and have been incorporated into risk equations such as the Framingham risk score, which can reasonably predict CVD over short- and long-term periods. Beyond risk factor levels at a single time point, recent evidence demonstrated that risk trajectories are differentially related to CVD risk. However, factors associated with suboptimal control or unstable CVD risk trajectories are not yet established.

OBJECTIVE

This study aims to examine factors associated with CVD risk trajectories in a semirural, multiethnic community-dwelling population.

METHODS

Data on demographic, socioeconomic, lifestyle, mental health, and cardiovascular factors were measured at baseline (2013) and during follow-up (2018) of the South East Asia Community Observatory cohort. The 10-year CVD risk change transition was computed. The trajectory patterns identified were improved; remained unchanged in low, moderate, or high CVD risk clusters; and worsened CVD risk trajectories. Multivariable regression analyses were used to examine the association between risk factors and changes in Framingham risk score and predicted CVD risk trajectory patterns with adjustments for concurrent risk factors.

RESULTS

Of the 6599 multiethnic community-dwelling individuals (n=3954, 59.92% female participants and n=2645, 40.08% male participants; mean age 55.3, SD 10.6 years), CVD risk increased over time in 33.37% (n=2202) of the sample population, while 24.38% (n=1609 remained in the high-risk trajectory pattern, which was reflected by the increased prevalence of all major CVD risk factors over the 5-year follow-up. Meanwhile, sex-specific prevalence data indicate that 21.44% (n=567) of male and 41.35% (n=1635) of female participants experienced an increase in CVD risk. However, a stark sex difference was observed in those remaining in the high CVD risk cluster, with 45.1% (n=1193) male participants and 10.52% (n=416) female participants. Regarding specific CVD risk factors, male participants exhibited a higher percentage increase in the prevalence of hypertension, antihypertensive medication use, smoking, and obesity, while female participants showed a higher prevalence of diabetes. Further regression analyses identified that Malay compared to Chinese (P<.001) and Indian (P=.04) ethnicity, nonmarried status (P<.001), full-time employment (P<.001), and depressive symptoms (P=.04) were all significantly associated with increased CVD risk scores. In addition, lower educational levels and frequently having meals from outside were significantly associated to higher odds of both worsening and remaining in high CVD risk trajectories.

CONCLUSIONS

Sociodemographics and mental health were found to be differently associated with CVD risk trajectories, warranting future research to disentangle the role of psychosocial disparities in CVD. Our findings carry public health implications, suggesting that the rise in major risk factors along with psychosocial disparities could potentially elevate CVD risk among individuals in underserved settings. More prevention efforts that continuously monitor CVD risk and consider changes in risk factors among vulnerable populations should be emphasized.

The Chinese visceral adiposity index: a novel indicator more closely related to cardiovascular disease than other abdominal obesity indices among postmenopausal women

BACKGROUND

Several abdominal obesity indices including waist circumference (WC), waist-hip ratio (WHR), visceral adiposity index (VAI), lipid accumulation product (LAP), and Chinese visceral adiposity index (CVAI) were considered effective and useful predictive markers for cardiovascular disease (CVD) in general populations or diabetic populations. However, studies investigating the associations between these indices among postmenopausal women are limited. Our study aimed to investigate the associations of the five indices with incident CVD and compare the predictive performance of CVAI with other abdominal obesity indices among postmenopausal women.

METHODS

A total of 1252 postmenopausal women without CVD at baseline were analyzed in our investigation based on a 10-year follow-up prospective cohort study. Link of each abdominal obesity index with CVD were assessed by the Cox regression analysis and the Kaplan-Meier curve. The receiver operating characteristic (ROC) curves were drawn to compare the predictive ability for CVD.

RESULTS

During the median follow-up of 120.53 months, 121 participants newly developed CVD. Compared to quartile 1 of LAP and CVAI, quartile 4 had increased risk to develop CVD after fully adjusted among postmenopausal women. When WC, VAI and CVAI considered as continuous variables, significant increased hazard ratios (HRs) for developing CVD were observed. The areas under the curve (AUC) of CVAI (0.632) was greatly higher than other indices (WC: 0.580, WHR: 0.538, LAP: 0.573, VAI: 0.540 respectively).

CONCLUSIONS

This study suggested that the abdominal obesity indices were associated with the risk of CVD excluded WHR and highlighted that CVAI might be the most valuable abdominal obesity indicator for identifying the high risk of CVD in Chinese postmenopausal women.

The distribution of cardiovascular diseases in Tanzania: a spatio-temporal investigation

Cardiovascular Disease (CVD) is currently the major challenge to people's health and the world's top cause of death. In Tanzania, deaths due to CVD account for about 13% of the total deaths caused by the non-communicable diseases. This study examined the spatio-temporal clustering of CVDs from 2010 to 2019 in Tanzania for retrospective spatio-temporal analysis using the Bernoulli probability model on data sampled from four selected hospitals. Spatial scan statistics was performed to identify CVD clusters and the effect of covariates on the CVD incidences was examined using multiple logistic regression. It was found that there was a comparatively high risk of CVD during 2011-2015 followed by a decline during 2015-2019. The spatio-temporal analysis detected two high-risk disease clusters in the coastal and lake zones from 2012 to 2016 (p<0.001), with similar results produced by purely spatial analysis. The multiple logistic model showed that sex, age, blood pressure, body mass index (BMI), alcohol intake and smoking were significant predictors of CVD incidence.

Impact of a Precision Intervention for Vascular Health in Middle-Aged and Older Postmenopausal Women Using Polar Heart Rate Sensors: A 24-Week RCT Study Based on the New Compilation of Tai Chi (Bafa Wubu)

(1) Background: This study utilized a 24-week intervention incorporating heart rate sensors for real-time monitoring of intervention training, aiming to comprehensively assess the effects of Tai Chi on vascular endothelial function, atherosclerosis progression, and lipid metabolism. The insights gained may inform personalized non-pharmacological interventions to enhance the management of cardiovascular health in this population to provide sustainable benefits and improve quality of life. (2) Methods: Forty postmenopausal middle-aged and elderly women were randomly assigned to an exercise or control group. The exercise group underwent a 24-week Tai Chi (BaFa WuBu) training intervention with real-time heart rate monitoring using Polar sensors. Pre- and post-intervention assessments included body composition, blood pressure, vascularity, and blood parameters measured with the Inbody 720, Vascular Endothelial Function Detector, and Arteriosclerosis. Data were analyzed using SPSS 26.0 and mixed-design ANOVA to assess the effects of time, group, and their interactions on study outcomes. (3) Results: After training through 24 weeks of Tai Chi (BaFa WuBu) intervention, compared with the control group, systolic blood pressure in the exercise group was significantly lower (p < 0.05), and the difference between left and right arm pulse pressure, left and right ankle mean arterial pressure, left and right side baPWV, left and right side ABI, TC, TG, LDL, and blood pressure viscosity were all very significantly lower (p < 0.01), and the diastolic blood pressure was significantly higher (p < 0.05). Compared with baseline values in the exercise group, systolic blood pressure, right and left arm pulse pressure difference, right and left ankle mean arterial pressure, right and left side baPWV, right and left side ABI, TC, TG, LDL, and blood pressure viscosity decreased very significantly (p < 0.01) and diastolic blood pressure and FMD increased very significantly (p < 0.01) in the exercise group after the intervention. (4) Conclusions: In our study, a 24-week Tai Chi (BaFa WuBu) program significantly improved vascular health in middle-aged and older postmenopausal women. This simplified Tai Chi form is gentle and effective, ideal for older adults. Regular practice led to reduced vascular obstruction, improved lipid metabolism, and enhanced vascular endothelial function, crucial for preventing vascular diseases. The real-time heart rate sensors used were pivotal, enabling precise monitoring and adjustment of exercise intensity, thereby enhancing the study's scientific rigor and supporting Tai Chi (BaFa WuBu) as a beneficial therapeutic exercise.

Association between obesity and common mental disorders in women: a population-based study in Southern Brazil

PURPOSE

The study aimed to investigate the relationship between obesity and common mental disorders (CMD) among women.

METHODS

This is a cross-sectional population-based study with a representative sample of 981 adult women (20-60 years of age) living in the urban area of the municipality of São Leopoldo, RS, Brazil, in 2015. The presence of CMD was assessed using the Self-Reporting Questionnaire (SRQ-20 ≥ 8). Obesity was defined by body mass index (BMI ≥ 30.0 kg/m2). Prevalence ratios (PRs) for the association between obesity and CMD were measured by Poisson regression with robust variance, including their respective 95% confidence intervals (CIs).

RESULTS

The mean age of the sample was 40.3 years (standard deviation = 11.4 years). The prevalence of CMD was 33.7% (95% CI 30.8-36.7), while obesity was 31.2% (95% CI 28.3-34.1). The occurrence of CMD was higher in women with low levels of education and belonging to lower economic class, as well as smokers and those who were insufficiently active. Obesity was more prevalent in older women (50-60 years old) with less schooling, who did not consume alcohol, and those who were insufficiently active. After adjusting for potential confounding factors, women with obesity were 22% more likely to have CMD when compared to those without obesity (PR = 1.22; 95% CI 1.02-1.45; p = 0.030).

CONCLUSIONS

This study demonstrated a significant association between obesity and the presence of CMD among women. Additionally, the prevalence of obesity and CMD were high in this population group.

Empirical analysis of health-related behaviors among older Hakka adults: a latent class analysis

Background

Little is known about health-related behaviors of the older Hakka population in China. We aimed to explore the characteristics and correlates of health-related behaviors among older Hakka adults.

Methods

We used data from the China's Health-Related Quality of Life Survey for Older Adults 2018. Latent class analysis (LCA) defined latent classes of health-related behaviors for 1,262 older Hakka adults aged 60 and above. Generalized linear regression and multinomial logistic regression analysis were used to identify factors influencing the number and the latent classes of health-related behaviors, respectively.

Results

The LCA showed that the latent classes could be stratified as the risk group (14.82%), healthy group (55.71%), and inactive group (29.48%). Sex, age, years of education, current residence, living arrangement, average annual household income, and currently employed were associated with the number of healthy behaviors. Compared with the participants in the healthy group, widowed/others (OR = 5.85, 95% CI = 3.27, 10.48), had 15,001-30,000 (OR = 2.05, 95% CI = 1.21, 3.47) and 60,001 or higher (OR = 3.78, 95% CI = 1.26, 11.36) average annual household income, and currently employed (OR = 3.40, 95% CI = 1.99, 5.81) were highly associated with risk group. Additionally, the participants who are widowed/others (OR = 4.30, 95% CI = 2.70, 6.85) and currently employed (OR = 1.95, 95% CI = 1.27, 2.98) were highly associated with the inactive group.

Conclusion

This study identified factors specifically associated with older Hakka adults' health-related behaviors from an LCA perspective. The findings indicate that policymakers should give more attention to older adults living alone and implement practical interventions to promote health-related behaviors among them.

Women's reproductive risk score and healthy lifestyle modification in cardiovascular disease: Findings from the UK Biobank

BACKGROUND AND AIMS

Reproductive risk factors are associated with increased risk of cardiovascular disease (CVD) in women. However, the combined effects of the composite reproductive risk factors on CVD are unknown. This study was performed to construct a reproductive risk score (RRS) to measure reproductive status, examine the association between RRS and CVD, and explore the modification effect of healthy lifestyle on the association in women in the UK Biobank cohort.

METHODS

The RRS was constructed in 74,141 female participants with data about the items derived for the RRS in the UK Biobank. The RRS was derived from 17 baseline variables, all of which indicated women's reproductive health status. We defined four categories of RRS status: low-risk group (score 0-1); low-intermediate group (score 2-3); high-intermediate group (score 4-5); and high-risk group (score 6-13). We also constructed a healthy lifestyle score (HLS) with five related factors, and categorized into unhealthy lifestyle group (score: 0-1), intermediate lifestyle group (score: 2-3) and healthy lifestyle group (score: 4-5).

RESULTS

Each point increase in the RRS was associated with a 22 % higher risk of CVD (adjusted hazard ratio (aHR): 1.22; 95 % confidence interval (CI): 1.16 to 1.28), 23 % higher risk of IHD (1.23; 1.17 to 1.31) and 19 % higher risk of stroke (1.19; 1.07 to 1.32). The percentage population-attribution risks (PAR%) were 16 % (95 % CI: 8 to 24) for CVD, 15 % (95 % CI: 6 to 24) for IHD and 18 % (95 % CI: 1 to 33) for stroke. A healthy lifestyle significantly attenuated RRS associations with the incidence of CVD and IHD. The attributable proportions due to additive interaction (p < 0.001) between RRS and HLS were 0.14 (95 % CI: 0.07 to 0.22) for CVD and 0.15 (95 % CI: 0.09 to 0.23) for IHD, respectively.

CONCLUSIONS

High RRS was associated with increased risks of CVD, IHD and stroke in female participants in the UK Biobank. The early-stage identification of women with reproductive risk using synthesised indicators and appropriate healthy lifestyle interventions could be useful for the prevention of early CVD and the extension of healthy active life expectancy.

Genetic predisposition, modifiable lifestyles, and their joint effects on human lifespan: evidence from multiple cohort studies

OBJECTIVE

To investigate the associations across genetic and lifestyle factors with lifespan.

DESIGN

A longitudinal cohort study.

SETTING

UK Biobank.

PARTICIPANTS

353 742 adults of European ancestry, who were recruited from 2006 to 2010 and were followed up until 2021.

EXPOSURES

A polygenic risk score for lifespan with long (highest quintile) risk categories and a weighted healthy lifestyle score, including no current smoking, moderate alcohol consumption, regular physical activity, healthy body shape, adequate sleep duration, and a healthy diet, categorised into favourable, intermediate, and unfavourable lifestyles.

MAIN OUTCOME MEASURES

Lifespan defined as the date of death or the censor date minus the date of birth.

RESULTS

Of the included 353 742 participants of European ancestry with a median follow-up of 12.86 years, 24 239 death cases were identified. Participants were grouped into three genetically determined lifespan categories including long (20.1%), intermediate (60.1%), and short (19.8%), and into three lifestyle score categories including favourable (23.1%), intermediate (55.6%), and unfavourable (21.3%). The hazard ratio (HR) of death for individuals with a genetic predisposition to a short lifespan was 1.21 (95% CI 1.16 to 1.26) compared to those with a genetic predisposition to a long lifespan. The HR of death for individuals in the unfavourable lifestyle category was 1.78 (95% CI 1.71 to 1.85), compared with those in the favourable lifestyle category. Participants with a genetic predisposition to a short lifespan and an unfavourable lifestyle had 2.04 times (95% CI 1.87 to 2.22) higher rates of death compared with those with a genetic predisposition to a long lifespan and a favourable lifestyle. No multiplicative interaction was detected between the polygenic risk score of lifespan and the weighted healthy lifestyle score (p=0.10). The optimal combination of healthy lifestyles, including never smoking, regular physical activity, adequate sleep duration, and a healthy diet, was derived to decrease risk of premature death (death before 75 years).

CONCLUSION

Genetic and lifestyle factors were independently associated with lifespan. Adherence to healthy lifestyles could largely attenuate the genetic risk of a shorter lifespan or premature death. The optimal combination of healthy lifestyles could convey better benefits for a longer lifespan, regardless of genetic background.

The Role of Psychosocial Stress on Cardiovascular Disease in Women: JACC State-of-the-Art Review

Psychosocial stress can affect cardiovascular health through multiple pathways. Certain stressors, such as socioeconomic disadvantage, childhood adversity, intimate partner violence, and caregiving stress, are especially common among women. The consequences of stress begin at a young age and persist throughout the life course. This is especially true for women, among whom the burden of negative psychosocial experiences tends to be larger in young age and midlife. Menarche, pregnancy, and menopause can further exacerbate stress in vulnerable women. Not only is psychosocial adversity prevalent in women, but it could have more pronounced consequences for cardiovascular risk among women than among men. These differential effects could reside in sex differences in responses to stress, combined with women's propensity toward vasomotor reactivity, microvascular dysfunction, and inflammation. The bulk of evidence suggests that targeting stress could be an important strategy for cardiovascular risk reduction in women.

Mortality trend of ischemic heart disease (2008-2022): A retrospective analysis of epidemiological data

BACKGROUND

Age-sex specific trend analyses of ischemic heart disease (IHD)-related mortality and prevalent risk factors can improve our understanding and approach to the disease.

METHODS

We performed a 15-year retrospective epidemiological analysis of acute and chronic IHD-related mortality and prevalent cardiovascular risk factors using administrative data from Veneto, a socio-economically homogeneous Italian region. Standard mortality statistics using the underlying cause of death (UCOD) and deaths with any mention of IHD in death certificates (MCOD) from ICD-10 codes I20-I25 was performed between 2008 and 2022.

RESULTS

A total of 134,327 death certificates reported IHD-related deaths, representing 18.6% of all deaths. Proportional mortality decreased from 14.6% in 2008 to 7.8% in 2022 for deaths with IHD as the UCOD and from 23.5% to 14.6% for deaths with IHD among the MCOD. A more pronounced decline of proportionate and case-specific mortality rate was seen in women. The decline in mortality over the whole study period was larger for acute (vs. chronic) IHD. The COVID-19 pandemic led to a marked increase in mortality in 2020 (+12.2%) with a subsequent further decline. IHD-related deaths displayed a typical seasonal pattern with more deaths during winter. The prevalence of cardiovascular risk factors was higher in IHD (vs. no IHD) deaths: this association appeared more pronounced in younger adults.

CONCLUSIONS

We provided an analysis of epidemiological trends in IHD-related mortality and prevalence of risk factors. Our findings indicate a change in the pattern of cardiovascular deaths and may suggest a switch in death from acute to chronic conditions.

Health impacts of lifestyle and ambient air pollution patterns on all-cause mortality: a UK Biobank cohort study

BACKGROUND

Extensive evidence indicates that both lifestyle factors and air pollution are strongly associated with all-cause mortality. However, little studies in this field have integrated these two factors in order to examine their relationship with mortality and explore potential interactions.

METHODS

A cohort of 271,075 participants from the UK Biobank underwent analysis. Lifestyles in terms of five modifiable factors, namely smoking, alcohol consumption, physical activity, diet, and sleep quality, were classified as unhealthy (0-1 score), general (2-3 score), and healthy (4-5 score). Air pollution, including particle matter with a diameter ≤ 2.5 μm (PM2.5), particulate matter with a diameter ≤ 10 μm (PM10), particulate matter with a diameter 2.5-10 μm (PM2.5-10), nitrogen dioxide (NO2), and nitrogen oxides (NOx), was divided into three levels (high, moderate, and low) using Latent Profile Analysis (LPA). Cox proportional hazard regression analysis was performed to examine the links between lifestyle, air pollution, and all-cause mortality before and after adjustment for potential confounders. Restricted cubic spline curves featuring three knots were incorporated to determine nonlinear relationships. The robustness of the findings was assessed via subgroup and sensitivity analyses.

RESULTS

With unhealthy lifestyles have a significantly enhanced risk of death compared to people with general lifestyles (HR = 1.315, 95% CI, 1.277-1.355), while people with healthy lifestyles have a significantly lower risk of death (HR = 0.821, 95% CI, 0.785-0.858). Notably, the difference in risk between moderate air pollution and mortality risk remained insignificant (HR = 0.993, 95% CI, 0.945-1.044). High air pollution, on the other hand, was independently linked to increased mortality risk as compared to low air pollution (HR = 1.162, 95% CI, 1.124-1.201). The relationship between NOx, PM10, and PM2.5-10 and all-cause mortality was found to be nonlinear (p for nonlinearity < 0.05). Furthermore, no significant interaction was identified between lifestyle and air pollution with respect to all-cause mortality.

CONCLUSIONS

Exposure to ambient air pollution elevated the likelihood of mortality from any cause, which was impacted by individual lifestyles. To alleviate this hazard, it is crucial for authorities to escalate environmental interventions, while individuals should proactively embrace and sustain healthy lifestyles.

Healthy Lifestyle and the Likelihood of Becoming a Centenarian

Importance

Previous studies have reported that lifestyle factors were associated with life expectancy and/or mortality, but most of them studied the middle-aged or older age groups (aged ≥60 years), and few focused on people aged 80 years or older.

Objectives

To examine healthy lifestyle and the likelihood of becoming centenarians among people aged 80 years or older in China.

Design, Settings, and Participants

Using data from the Chinese Longitudinal Healthy Longevity Survey, a nationally representative and one of the largest prospective cohorts targeting people aged 80 years or older established in 1998, a community-based, prospective nested case-control study was performed. Data were analyzed from December 1, 2022, to April 15, 2024.

Exposures

A healthy lifestyle score for 100 (HLS-100, ranging from 0 to 6), including smoking, exercise, and dietary diversity, was constructed, with higher scores indicating potentially better health outcomes.

Main Outcomes and Measures

The primary outcome was survivorship to becoming a centenarian by 2018 (the end of follow-up). Information on sociodemographic characteristics, lifestyle factors, and other covariates was collected.

Results

The sample comprised 5222 individuals (61.7% women, mean [SD] age, 94.3 [3.3] years), including 1454 identified centenarians and 3768 controls (died before becoming centenarians) matched by age, sex, and year of entry. During a median follow-up of 5 (IQR, 3-7) years, 373 of 1486 individuals among the lowest HLS-100 (0-2) group and 276 of 851 individuals among the highest HLS-100 (5-6) group became centenarians. The adjusted odds ratio (AOR) comparing the highest vs the lowest HLS-100 groups was 1.61 (95% CI, 1.32-1.96; P < .001 for trend). An association was noted when we further treated centenarians with relatively healthy status as the outcome, as evaluated by self-reported chronic conditions, physical and cognitive function, and mental wellness (AOR, 1.54; 95% CI, 1.05-2.26). Similar results were observed in other sensitivity analyses.

Conclusions and Relevance

In this case-control study of Chinese older adults, adhering to a healthy lifestyle appears to be important even at late ages, suggesting that constructing strategic plans to improve lifestyle behaviors among all older adults may play a key role in promoting healthy aging and longevity.

Prospective associations between systolic blood pressure, serum cholesterol, and physical activity behaviour and the development of cardiovascular disease

AIMS

To systematically appraise and summarise meta-analyses of longitudinal studies to determine the effect size, and quality and certainty of the evidence summaries for systolic blood pressure (SBP), serum cholesterol, and physical activity behaviour in developing cardiovascular disease (CVD).

METHODS AND RESULTS

An umbrella review was conducted by searching MEDLINE, Embase, and Scopus databases. Eligible meta-analyses were longitudinal studies investigating the association between SBP, serum cholesterol, or physical activity behaviour on CVD development. Summary risk estimates were extracted. Quality and certainty of the evidence summaries of included records were performed using AMSTAR 2 and GRADE, respectively. Forty-one eligible records were found of which thirteen related to SBP, five to cholesterol, and twenty-three to physical activity behaviour. The quality and certainty of the evidence summaries were variable, with most studies rating 'low'. Reported risk estimates for the risk of developing CVD ranged from: no change to a 68% decreased risk for lower SBP; a 21% increased risk to a 44% decreased risk for lower cholesterol; and a 1% decreased risk to a 56% decreased risk for higher physical activity levels.

CONCLUSIONS

There were strong associations with CVD risk at the meta-analysis level for all three exposures, with a proportionally greater number of meta-analyses and primary studies for physical activity than SBP or serum cholesterol. Given the number of meta-analyses and similar CVD risk reductions and certainty of evidence associated with physical activity behaviour, there is a strong case for its routine assessment alongside SBP and serum cholesterol in primary CVD prevention.

The association between alcohol consumption and all-cause mortality: An umbrella review of systematic reviews using lifetime abstainers or low-volume drinkers as a reference group

BACKGROUND AND AIMS

Systematic reviews of the relationship between alcohol consumption and all-cause mortality have reported different relative risk (RR) curves, possibly due to the choice of reference group. Results have varied from 'J-shaped' curves, where low-volume consumption is associated with reduced risk, to monotonically increased risk with increasing consumption. We summarised the evidence on alcohol consumption and all-cause mortality exclusively from systematic reviews using lifetime abstainers or low-volume/occasional drinkers as the reference group.

METHODS

We conducted a systematic umbrella review of systematic reviews of the relationship between alcohol consumption and all-cause mortality in prospective cohort studies using a reference group of lifetime abstainers or low-volume/occasional drinkers. Several databases (PubMed/Medline/Embase/PsycINFO/Cochrane Library) were searched to March 2022. Reviews were assessed for risk of bias, and those with reference groups containing former drinkers were excluded.

RESULTS

From 2149 articles retrieved, 25 systematic reviews were identified, and five did not include former drinkers in the reference group. Four of the five included reviews had high risk of bias. Three reviews reported a J-shaped relationship between alcohol consumption and all-cause mortality with significant decreased risk for low-volume drinking (RR range 0.84 to 0.95), while two reviews did not. The one review at low risk of bias reported monotonically increased risk with greater consumption (RRs = 1.02, 1.13, 1.33 and 1.52 for low-, medium-, high- and higher-volume drinking, respectively, compared with occasional drinking). All five reviews reported significantly increased risk with higher levels of alcohol consumption (RR range 1.28 to 3.70). Sub-group analyses were reported by sex and age; however, there were evidence gaps for many important factors. Conversely, 17 of 20 excluded systematic reviews reported decreased mortality risk for low-volume drinking.

CONCLUSIONS

Over 70% of systematic reviews and meta-analyses published to March 2022 of all-cause mortality risk associated with alcohol consumption did not exclude former drinkers from the reference group and may therefore be biased by the 'sick-quitter effect'.

A cohort study of self-perception of ageing and all-cause mortality among older adults in China: a multiple mediators analysis

BACKGROUND

Positive self-perception of aging (SPA) is a well-known predictor of longevity, while how and to what extent SPA is linked with all-cause mortality among older adults is still unclear. This study aims to elucidate the relationship between positive SPA and all-cause mortality and its potential mediators among Chinese older adults.

METHODS

This is a 20-year dynamic cohort study conducted among 22,957 older adults aged ≥ 65 years old from a nationally representative sample. Positive SPA was measured using a validated 7-item scale. Potential mediators including health behaviors and social participation were collected using a self-reported questionnaire. Cox proportional hazards regression models were conducted to examine the association between positive SPA and all-cause mortality. A mediation analysis was conducted to determine whether health behaviors and social participation mediated the association between SPA and all-cause mortality.

RESULTS

Throughout follow-up (median [interquartile range], 46 [21-84] months), all-cause mortality was 87.4%. Compared with older adults with the lowest quartile positive SPA, hazard ratio(HR) of all-cause mortality among older adults with the second, third, and fourth quartile of positive SPA was 0.96(95%CI:0.93-1.00), 0.93(95%CI:0.90-0.99), and 0.92(95%CI:0.87-0.96) respectively after controlling for all potential mediators and covariates. The mediation analysis showed that regular daily vegetable intake, physical activity, and high social participation explained 41.1-48.5% of the variance in the association between positive SPA and all-cause mortality.

CONCLUSIONS

In this cohort study, we found that high positive SPA was associated with decreased all-cause mortality directly, and indirectly through healthy lifestyle behaviors and social participation. These findings suggest that interventions targeted at promoting or maintaining positive SPA may contribute to healthy ageing among older adults in China.

Association of a low-inflammatory diet with survival among adults: The role of cardiometabolic diseases and lifestyle

BACKGROUND & AIMS

Evidence on the association between dietary inflammation and longevity is limited. We aimed to examine the association of a low-inflammatory diet with mortality and longevity, and to explore whether cardiometabolic diseases (CMDs) and lifestyle factors may play a role in this association.

METHODS

Within the UK Biobank, 188,443 participants aged 39-72 years (mean 56.07) were followed for up to 16 years to detect survival status from the death registry. At baseline, dietary intake was assessed with a 24-h dietary record. An inflammatory diet index (IDI) was calculated as weighted sum of 31 food groups (including 14 anti-inflammatory and 17 pro-inflammatory) based on plasma high-sensitivity C-reactive protein levels, and tertiled as low, moderate, and high IDI scores. Baseline lifestyle beyond diet was assessed by summing the number of healthy lifestyle factors (i.e., never smoking, regular physical activity, and normal BMI) and categorized as unfavorable (≤1) and favorable (≥2). Presence of CMDs was defined as having any one of type 2 diabetes, ischemic heart disease, atrial fibrillation, heart failure, and stroke. Data were analyzed using Cox regression, Laplace regression, and generalized structural equation modelling.

RESULTS

During the follow-up (median 9.79 years, interquartile range: 9.68-10.57 years), 9178 (4.9%) participants died. In multi-adjusted Cox regression models, a low-inflammatory diet (i.e. low IDI score) was associated with lower risk of all-cause mortality [hazard ratio (HR) = 0.82, 95% confidence interval (CI): 0.78 to 0.86]. Laplace regression analysis showed that the multi-adjusted 10th percentile difference (10th PD, 95% CI) of death time was delayed by 0.80 (0.55, 1.06; P < 0.001) years for participants with a low IDI score compared to those with a high IDI score. In mediation analysis, 21.48% of the association between IDI and mortality was mediated by CMDs. In joint effect analysis, participants with a low IDI score and favorable lifestyle had a 42% lower risk of death (HR = 0.58, 95% CI: 0.54, 0.62) compared to those with a high IDI score and unfavorable lifestyle. There was a significant additive interaction between low IDI score and favorable lifestyle on decreased mortality.

CONCLUSIONS

A low-inflammatory diet is associated with a lower risk of death and could prolong survival time. CMDs may partially mediate the IDI-mortality association. A favorable lifestyle beyond diet may augment the positive effect of a low-inflammatory diet on longevity.

The menopausal transition period and cardiovascular risk

The menopausal transition period spans, on average, 2-8 years before the final menstrual period and is associated with an increase in clinical and subclinical cardiovascular risk. In this Review, we discuss the metabolic and cardiovascular changes that occur during the menopausal transition period and the role of ovarian ageing, chronological ageing and other ageing-related risk factors in mediating these changes. Disentangling the relative contributions of chronological and reproductive ageing to cardiovascular risk is challenging, but data from longitudinal studies in women transitioning from premenopause to post-menopause have provided valuable insights. We also discuss evidence on how cardiovascular risk is altered by premature or early menopause, surgical menopause, and vasomotor and other menopausal symptoms. Whether targeted interventions can slow the progression of atherosclerosis and subclinical disease during the menopausal transition, thus delaying or preventing the onset of cardiovascular events, remains to be determined. Furthermore, we consider the recommended strategies for cardiovascular risk reduction in women undergoing menopausal transition using the framework of the American Heart Association's Life's Essential 8 key measures for improving and maintaining cardiovascular health, and discuss the cardiovascular risks and benefits of menopausal hormone therapy. Finally, we also discuss novel therapies that might benefit this population in reducing cardiovascular risk.

Time to pregnancy and life expectancy: a cohort study of 18 796 pregnant couples

STUDY QUESTION

Is fecundity, measured as time to pregnancy (TTP), associated with mortality in parents?

SUMMARY ANSWER

Prolonged TTP is associated with increased mortality in both mothers and fathers in a dose-response manner.

WHAT IS KNOWN ALREADY

Several studies have linked both male and female fecundity to mortality. In women, infertility has been linked to several diseases, but studies suggest that the underlying conditions, rather than infertility, increase mortality.

STUDY DESIGN, SIZE, DURATION

A prospective cohort study was carried out on 18 796 pregnant couples, in which the pregnant women attended prophylactic antenatal care between 1973 and 1987 at a primary and tertiary care unit. The couples were followed in Danish mortality registers from their child's birth date until death or until 2018. The follow-up period was up to 47 years, and there was complete follow-up until death, emigration or end of study.

PARTICIPANTS/MATERIALS, SETTING, METHODS

At the first antenatal visit, the pregnant women were asked to report the time to the current pregnancy. Inclusion was restricted to the first pregnancy, and TTP was categorised into <12 months, ≥12 months, not planned, and not available. In sub-analyses, TTP ≥12 was further categorized into 12-35, 36-60, and >60 months. Information for parents was linked to several Danish nationwide health registries. Survival analysis was used to estimate the hazard ratios (HRs) with a 95% CI for survival and adjusted for age at the first attempt to become pregnant, year of birth, socioeconomic status, mother's smoking during pregnancy, and mother's BMI.

MAIN RESULTS AND THE ROLE OF CHANCE

Mothers and fathers with TTP >60 months survived, respectively, 3.5 (95% CI: 2.6-4.3) and 2.7 (95% CI: 1.8-3.7) years shorter than parents with a TTP <12 months. The mortality was higher for fathers (HR: 1.21, 95% CI: 1.09-1.34) and mothers (HR: 1.29, 95% CI: 1.12-1.49) with TTP ≥12 months compared to parents with TTP <12 months. The risk of all-cause mortality during the study period increased in a dose-response manner with the highest adjusted HR of 1.98 (95% CI: 1.62-2.41) for fathers and 2.03 (95% CI: 1.56-2.63) for mothers with TTP >60 months. Prolonged TTP was associated with several different causes of death in both fathers and mothers, indicating that the underlying causes of the relation between fecundity and survival may be multi-factorial.

LIMITATIONS, REASONS FOR CAUTION

A limitation is that fecundity is measured using a pregnancy-based approach. Thus, the cohort is conditioned on fertility success and excludes sterile couples, unsuccessful attempts and spontaneous abortions. The question used to measure TTP when the pregnant woman was interviewed at her first attended prophylactic antenatal care: 'From the time you wanted a pregnancy until it occurred, how much time passed?' could potentially have led to serious misclassification if the woman did not answer on time starting unprotected intercourse but on the start of wishing to have a child.

WIDER IMPLICATIONS OF THE FINDINGS

We found that TTP is a strong marker of survival, contributing to the still-emerging evidence that fecundity in men and women reflects their health and survival potential.

Dose-Response Relationship of Physical Activity with All-Cause Mortality among Older Adults: An Umbrella Review

OBJECTIVES

To examine the dose-response relationship between physical activity (PA) and all-cause and cardiovascular disease (CVD) mortality, specifically among older adults.

DESIGN

Umbrella review.

SETTING AND PARTICIPANTS

Eligible studies included systematic reviews with meta-analyses that investigated the association of aerobic PA, muscle-strengthening activity, and multicomponent PA, including exercise programs (such as aerobic, muscle strengthening, and balance training), with all-cause and CVD mortality among older adults aged ≥60 years.

METHODS

We performed a literature search in PubMed, CINAHL, and the Cochrane Library for eligible studies published between January 2017 and March 2023 to update an umbrella review initially conducted by the United States 2018 PA Guidelines Advisory Committee. Studies included in the 2018 US PA and 2020 World Health Organization (WHO) Guidelines were also reviewed. In addition, meta-analyses that reported effect sizes stratified by age and recruiting older adults (aged ≥60 years) were included.

RESULTS

Overall, 16 relevant systematic reviews (10 from our review and 6 from the US and WHO guidelines) met the inclusion criteria. All these reviews showed that 7.5 to 15.0 metabolic equivalents (METs)-hours/week (around the recommended PA levels outlined in the US and WHO guidelines) substantially reduced mortality risks among older adults (approximately 19%-30% for all-cause mortality and 25%-34% for CVD mortality). Moreover, 15.0 to 22.5 MET-hours/week, exceeding the guideline-recommended PA levels, resulted in greater reductions in mortality risks by 35% to 37% and 38% to 40%, respectively.

CONCLUSIONS AND IMPLICATIONS

PA substantially reduced all-cause and CVD mortality risks among older adults. Larger risk reductions may be achieved by engaging in PA levels higher than those recommended by the current international PA guidelines. Our findings suggest that recommending higher PA levels beyond the current guidelines may benefit older adults when developing future international PA guidelines.

Mortality in Women with Coronary Artery Disease in Paraná State, Brazil: A Bayesian Spatiotemporal Analysis

Background

Mortality resulting from coronary artery disease (CAD) among women is a complex issue influenced by many factors that encompass not only biological distinctions but also sociocultural, economic, and healthcare-related components. Understanding these factors is crucial to enhance healthcare provisions. Therefore, this study seeks to identify the social and clinical variables related to the risk of mortality caused by CAD in women aged 50 to 79 years old in Paraná state, Brazil, between 2010 and 2019.

Methods

This is an ecological study based on secondary data sourced from E-Gestor, IPARDES, and DATASUS. We developed a model that integrates both raw and standardized coronary artery disease (CAD) mortality rates, along with sociodemographic and healthcare service variables. We employed Bayesian spatiotemporal analysis with Markov Chain Monte Carlo simulations to assess the relative risk of CAD mortality, focusing specifically on women across the state of Paraná.

Results

A total of 14,603 deaths from CAD occurred between 2010 and 2019. Overall, temporal analysis indicates that the risk of CAD mortality decreased by around 22.6% between 2010 (RR of 1.06) and 2019 (RR of 0.82). This decline was most prominent after 2014. The exercise stress testing rate, accessibility of cardiology centers, and IPARDES municipal performance index contributed to the reduction of CAD mortality by approximately 4%, 8%, and 34%, respectively. However, locally, regions in the Central-West, Central-South, Central-East, and Southern regions of the Central-North parts of the state exhibited risks higher-than-expected.

Conclusion

In the last decade, CAD-related deaths among women in Paraná state decreased. This was influenced by more exercise stress testing, better access to cardiology centers, improved municipal performance index. Yet, elevated risks of deaths persist in certain regions due to medical disparities and varying municipal development. Therefore, prioritizing strategies to enhance women's access to cardiovascular healthcare in less developed regions is crucial.

Impact of cardiovascular disease on health-related quality of life among older adults in eastern China: evidence from a national cross-sectional survey

Objective

This study explores the health-related quality of life (HRQoL) scores of Chinese older adults with Cardiovascular Disease(CVD) using the EQ-5D-3L, the aim of this study is to investigate the association between health and HRQoL in older adults with CVD.

Methods

The data for this study were obtained from a cross-sectional study involving older adults residing in Chinese communities The EQ-5D-3L is used to measure the HRQoL scores in the older adults with CVD. One-way analyses were conducted using the Wilcoxon rank sum test and the Kruskal-Wallis H test to assess differences between groups. A binary logistic regression model was employed to analyze the influence each variable has on the presence of "any problem" on each dimension of EQ-5D-3L in older adults with CVD. An ordinal least squares (OLS) model is used to assess the relationship between older adults with CVD and HRQoL.

Results

The mean EQ-5D-3L score for older adults with CVD is 0.774. 40.0% of older adults with CVD reported problems with pain/discomfort, followed by Mobility (35.9%), Self-care (31.5%), and Anxiety/depression (17.0%). Binary logistic regression models show that financial resources were the main factor influencing the five dimensions of EQ-5D-3L. The OLS model further indicates that younger age, financial resources, and a lower number of chronic conditions among older adults with CVD are associated with higher HRQoL scores.

Conclusion

Chinese older adults with CVD have low HRQoL scores. Variousfactors influence both overall HRQoL scores and scores on each EQ-5D-3L dimension. This study is helpful in enhancing society's attention to the HRQoL of older adults with CVD and taking targeted measures to improve them.

Machine-learning model predicting quality of life using multifaceted lifestyles in middle-aged South Korean adults: a cross-sectional study

BACKGROUND

In the context of population aging, advances in healthcare technology, and growing interest in healthy aging and higher quality of life (QOL), have gained central focus in public health, particularly among middle-aged adults.

METHODS

This study presented an optimal prediction model for QOL among middle-aged South Korean adults (N = 4,048; aged 30-55 years) using a machine-learning technique. Community-based South Korean population data were sampled through multistage stratified cluster sampling. Twenty-one variables related to individual factors and various lifestyle patterns were surveyed. QOL was assessed using the Short Form Health Survey (SF-12) and categorized into total QOL, physical component score (PCS), and mental component score (MCS). Seven machine-learning algorithms were used to predict QOL: decision tree, Gaussian Naïve Bayes, k-nearest neighbor, logistic regression, extreme gradient boosting, random forest, and support vector machine. Data imbalance was resolved with the synthetic minority oversampling technique (SMOTE). Random forest was used to compare feature importance and visualize the importance of each variable.

RESULTS

For predicting QOL deterioration, the random forest method showed the highest performance. The random forest algorithm using SMOTE showed the highest area under the receiver operating characteristic (AUC) for total QOL (0.822), PCS (0.770), and MCS (0.786). Applying the data, SMOTE enhanced model performance by up to 0.111 AUC. Although feature importance differed across the three QOL indices, stress and sleep quality were identified as the most potent predictors of QOL. Random forest generated the most accurate prediction of QOL among middle-aged adults; the model showed that stress and sleep quality management were essential for improving QOL.

CONCLUSION

The results highlighted the need to develop a health management program for middle-aged adults that enables multidisciplinary management of QOL.

Immune-mediated inflammatory diseases and the risk of valvular heart disease: a Mendelian randomization study

BACKGROUND

Observational studies have suggested that immune-mediated inflammatory diseases (IMIDs) are associated with a higher risk of valvular heart disease (VHD). But the potential causal association is not clear. Therefore, we used Mendelian randomization (MR) analysis to assess the causal association of IMIDs with VHD risk.

METHODS

A two-sample MR analysis was performed to confirm the causal association of several common IMIDs (systemic lupus erythematosus, SLE; rheumatoid arthritis, RA; multiple sclerosis, MS; ankylosing spondylitis, AS; psoriasis, PSO; inflammatory bowel disease, IBD) with the risk of VHD. The exposure data is derived from published genome-wide association studies (GWASs) and outcome data come from the FinnGen database (47,003 cases and 182,971 controls). Inverse-variance weighted (IVW), MR-Egger, and weighted median methods were performed to assess the causal association. The study design applied univariable MR and multivariable MR.

RESULTS

The MR analysis indicated that several genetically predicted IMIDs increased the risk of VHD, including SLE (odds ratio (OR) = 1.014; 95% confidence interval (CI) =  < 1.001,1.028 > ; p = 0.036), RA (OR = 1.017; 95% CI =  < 1.002,1.031 > ; p = 0.025), and IBD (OR = 1.018; 95% CI =  < 1.002,1.033 > ; p = 0.023). Multivariable MR indicated that the adverse effect of these IMIDs on VHD was dampened to varying degrees after adjusting for smoking, obesity, coronary artery disease, and hypertension.

CONCLUSION

Our findings support the first genetic evidence of the causality of genetically predicted IMIDs with the risk of developing into VHD. Our results deliver a viewpoint that further active intervention needs to be explored to mitigate VHD risk in patients with SLE, RA, and IBD. Key Points • Genetically predicted systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and inflammatory bowel disease (IBD) are causally associated with valvular heart disease (VHD). • To reduce the risk of VHD in patients with SLE, RA, and IBD, active interventions should be further explored.

Physical inactivity among American single-female caregivers: An analysis of the 2020 behavioral risk factor surveillance system

BACKGROUND

Many adults in the United States do not reach the recommended levels of activity needed for health benefits. Single-female caregivers present a unique and vulnerable population that is often less active than their partnered peers or single-male caregivers.

OBJECTIVE

The primary objective of this cross-sectional investigation was to identify the prevalence of physical inactivity in single-family, female-led households and determine differences in personal factors and social characteristics between physically active and not physically active single-female caregivers. A secondary objective was to examine associations among the social characteristic variables and physical inactivity in single-female caregiver households. Finally, we examined the odds single-female caregivers who are physically inactive reported chronic health conditions.

DESIGN

Cross-sectional survey design.

METHODS

We used the 2020 Behavioral Risk Factor Surveillance System (BRFSS) data. Participants were selected based on pre-determined criteria for inclusion.

RESULTS

There was a 39.3% prevalence of physical inactivity among single-female caregivers in the sample. Single-female caregivers who were physically inactive had greater odds of having a history of multiple chronic health conditions.

CONCLUSION

Healthcare providers and other community stakeholders should explore existing physical activity promotion strategies to increase physical activity in single-female caregivers. Future research should employ more rigorous, prospective research designs to determine if these chronic conditions and various social characteristics are caused by physical inactivity.

Lifestyle and ADL Are Prioritized Factors Influencing All-Cause Mortality Risk Among Oldest Old: A Population-Based Cohort Study

To identify key factors affecting all-cause mortality in the elderly aged 80 years and above. Data from Chinese Longitudinal Healthy Longevity Survey (2011-2018) were utilized (N = 3993). A healthy lifestyle score was obtained by assigning 8 factors: smoking, drinking, exercise, sleep duration, social activity, waist circumference, BMI, and healthful plant-based diet index. Cox regression and decision tree model were used to identify factors influencing the mortality risk. Lifestyle and activities of daily living (ADL) were 2 of the most important modifiable factors influencing the mortality risk of the oldest seniors. A higher healthy lifestyle score was associated with lower mortality risk. The HR (95% CI) of death risk in Q2, Q3, and Q4 groups were 0.91 (0.81-1.01), 0.78 (0.71-0.86), and 0.64 (0.58-0.71), respectively, when compared with the Q1 group of healthy lifestyle score. Elderly with ADL disability had a higher mortality rate than those without ADL disability. When the elderly already have ADL disability, the healthier the lifestyle, the lower the mortality rate. Among individuals aged 80 to 89 years with ADL disability, the mortality rate was higher in the healthy lifestyle score Q1-Q2 groups (92.1%) than that in the Q3-Q4 groups (71.6%). Similar results were observed among subjects aged 90 to 99 years with ADL disability (Q1-Q2: 97.9%, Q3-Q4: 92.1%). For centenarians without ADL disability, maintaining a healthy lifestyle significantly reduced mortality (Q1-Q3: 90.5%, Q4: 75.5%). Caregivers should prioritize the consideration of lifestyle and ADL in their healthcare practices of the oldest old.

Menopause: Physiology, definitions, and symptoms

The menopause transition is usually a gradual process occurring over many years, caused by the cessation of ovarian reproductive function, resulting in the end of menstrual bleeding. In the peri-menopause, ovarian function and therefore the production of the hormones oestrogen, progesterone and testosterone can fluctuate greatly, leading to a wide variety of symptoms, affecting multiple organ systems. Menopause and the management of its associated symptoms can be very challenging for patients and clinicians alike and can negatively impact quality of life. The management options include lifestyle adjustment, talking therapies, dietary supplements as well as prescribed medications, including hormone replacement therapy. The UK's average life expectancy for women is approximately 81 years. Therefore, women will now live up to a third of their life being either peri- or postmenopausal. Thus, understanding and treating, where possible, the symptoms of menopause is essential to reduce the burden associated with this physiological state.

Impact of lifestyle and psychological resilience on survival among the oldest-old in China: a cohort study

Introduction

Healthy lifestyles and psychological resilience are important factors influencing the life expectancy of the oldest-old (≥80 years). Stratified by urban and rural groups, this study used a 10-year cohort to examine the mechanism of lifestyle and psychological resilience on the survival of the oldest-old in China.

Methods

This study used the China Longitudinal Healthy Longevity Survey datasets spanning from 2008 to 2018, and 9,250 eligible participants were included. The primary outcome variable was all-cause mortality, and independent variables included healthy lifestyle index and psychological resilience. Six covariates were included in the survival analysis and moderation-mediation model, such as gender and annual household income.

Results

This study found that the oldest-old with five healthy lifestyles had the longest survival time, averaging 59.40 months for urban individuals and 50.08 months for rural individuals. As the lifestyle index increased, the survival rate significantly increased. The Cox regression showed that for the urban oldest-old, the lifestyle index served as a protective factor for survival outcomes. However, this effect lost statistical significance among rural oldest-old individuals. For urban oldest-old individuals, psychological resilience significantly mediated and moderated the effect of the lifestyle index on survival status, but the moderating effect was not statistically significant for the rural ones.

Discussion

Overall, healthy lifestyles and psychological resilience can be effective in enhancing the survival of the oldest-old, and there are differences between urban and rural population, so different interventions should be adopted for urban and rural areas to achieve longer life in China.

The predictive accuracy of coronary heart disease risk prediction models in rural Northwestern China

Cardiovascular risk models developed may have limitations when applied to rural Chinese. This study validated and compared the Framingham Risk Score (FRS) and Prediction for Atherosclerotic Cardiovascular Disease Risk in China (PAR) models in predicting 10-year risk of coronary heart disease (CHD) in a rural cohort in Ningxia, China from 2008 to 2019. The FRS and PAR models were validated by estimating predicted events, C index, calibration χ2 and plots. 1381 adults without CHD at baseline were followed up for 9.75 years on average. 168 CHD cases were observed. The FRS and PAR underestimated CHD events by 22 % and 46 % for the total population, while overestimated for males by 152 % and 78 %, respectively. The C index was slightly higher for PAR than FRS. Both models showed weak calibration with chi-square values above 20 (p < 0.001). Bland-Altman plots indicated FRS predicted higher CHD risk than PAR, lacking consistency. Overall, FRS and PAR demonstrated limited performance in predicting 10-year CHD risk in this rural population. PAR had slightly better discrimination than FRS, but require further improvement in calibration and individual risk estimation to suit the rural population in Northwest China.
