[PMID: 37794130 PMCID: PMC10844075 DOI: 10.1038/s41371-023-00867-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 09/07/2023] [Accepted: 09/26/2023] [Indexed: 10/06/2023]
Abstract
It is still debated whether arterial elasticity provides prognostic information for cardiovascular risk beyond blood pressure measurements in a healthy population. To investigate the association between arterial elasticity obtained by radial artery pulse wave analysis and risk for cardiovascular diseases (CVD) in men and women. In 2002-2005, 2362 individuals (men=1186, 50.2%) not taking antihypertensive medication were included. C2 (small artery elasticity) was measured using the HDI/Pulse Wave CR2000. Data on acute myocardial infarction or stroke, fatal or non-fatal, was obtained between 2002-2019. Cox- regression was used to investigate associations between C2 and future CVD, adjusting for confounding factors such as age, sex, systolic blood pressure, heart rate, HOMA-IR (Homeostatic Model Assessment for Insulin Resistance), LDL- cholesterol, CRP (C-Reactive Protein), alcohol consumption, smoking and physical activity. At baseline, the mean age of 46 ± 10.6 years and over the follow-up period, we observed 108 events 70 events in men [event rate: 5.9%], 38 in women [event rate: 3.2%]. In the fully adjusted model, and for each quartile decrease in C2, there was a significant increase in the risk for incident CVD by 36%. (HR = 1.36, 95% CI: 1.01-1.82, p = 0.041). The results were accentuated for all men (HR = 1.74, 95% CI: 1.21-2.50, p = 0.003) and women over the age of 50 years (HR = 1.70, 95% CI: 0.69-4.20). We showed a strong and independent association between C2 and CVD in men. In women after menopause, similar tendencies and effect sizes were observed.

Association between self-reported alcohol consumption and diastolic dysfunction: a cross-sectional study. BMJ Open 2023; 13:e069937. [PMID: 37821143 PMCID: PMC10583109 DOI: 10.1136/bmjopen-2022-069937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 09/26/2023] [Indexed: 10/13/2023] Open
Abstract
BACKGROUND AND OBJECTIVES While alcohol consumption is associated with common risk factors for diastolic dysfunction the independent impact of low levels of alcohol consumption on this condition in a community setting is still unclear.Thus, the aim of this study was to explore this association in a representative population sample employing optimal echocardiographic techniques. DESIGN Cross-sectional observational study in community-based population. SETTINGS, PARTICIPANTS AND METHODS Participants between 30 and 75 years of age were consecutively invited to a physical examination, interview, conventional echocardiography, including Tissue Velocity Imaging. Diastolic dysfunction was defined according to the European Society of Cardiology criteria, excluding subjects with ejection fraction <45%, self-reported history of heart failure or atrial fibrillation on ECG. Self-reported alcohol intake using a validated questionnaire was categorised as no intake, low and medium-high intake. RESULTS In total, 500 men and 538 women (mean age 55.4±13) were successfully examined. Diastolic dysfunction was identified in 16% (79/500) of the men and 13% (58/538) of the women. The multivariable adjusted model revealed a strong and independent association between alcohol intake and diastolic dysfunction. In fact, using no alcohol intake as reference, diastolic dysfunction was independently associated with alcohol consumption in a dose-dependent fashion; low consumption, OR 2.3 (95% CI 1.3 to 4.0) and medium-high consumption OR 3.1 (95% CI 1.6 to 6.2), respectively. CONCLUSION There was a significant association between alcohol consumption and diastolic dysfunction starting already at low levels that was supported by a dose-dependent pattern. These results need confirmatory studies and are important in public health policies.

Validation of a single question to measure internal health locus of control in Swedish primary care. Scand J Psychol 2023; 64:674-678. [PMID: 37102405 DOI: 10.1111/sjop.12923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 02/22/2023] [Accepted: 04/04/2023] [Indexed: 04/28/2023]
Abstract
BACKGROUND Behavioral risk factors are highlighted in the prevention of diabetes and cardiovascular disease. Screening for health locus of control could be a feasible way to better identify individuals who could benefit from preventive behavioral change interventions. The aim of the study was to investigate the correlation between a single question measuring internal health locus of control (IHLC) and the Multidimensional Health Locus of Control Scale (MHLC) and to assess how IHLC relates to the General Self-Efficacy scale (GSE) in a primary care setting. METHODS Primary care patients, aged 18 and older, attending three primary care centers in southwest Sweden were consecutively asked to anonymously participate in the study. The patients were given a questionnaire and instructed to return the questionnaire in a sealed box in the waiting room. RESULTS In all, 519 patients were included. The correlation between MHLC Internality and IHLC was weak (r = 0.21, p < 0.001). An increase of one point on the internality scale of the MHLC gave an odds ratio of 1.19 (95% CI 1.11-1.28) for reporting high IHLC, and thus a five-point increase gave a doubled likelihood, OR = 2.40, CI 1.67-3.46. The results for the other scales of the MHLC and GSE were similar. CONCLUSION In this study, we found weak but statistically significant support for the single-question IHLC as a measure of internal health locus of control. Given that the correlation was weak, we recommend using the MHLC when possible.

Abstract
OBJECTIVE To investigate the association between sex hormone-binding globulin (SHBG) levels, change in blood pressure and development of hypertension. METHODS In a community-based study, we examined 2816 middle-aged participants with focus on cardiometabolic risk factors in 2002-2005. A representative sample of 1954 men and women was invited to follow-up in 2012-2014 and 1327 were included in a second study visit. Mean follow-up time was 9.7 years. Blood pressure was measured according to the guidelines from the seventh Joint National Committee of Hypertension, and new cases of hypertension were recorded. SHBG was measured at baseline. The association between SHBG, blood pressure and new cases of hypertension was investigated using linear regression analyses and logistic regression analyses after excluding individuals treated with blood pressure-lowering drugs. RESULTS Mean SBP and DBP at follow-up was 123 and 72 mmHg, respectively, and mean increase from baseline was 5.8 and 2.9 mmHg. During the follow-up time, 167 new cases of hypertension (16.1%) were identified. One standard deviation (SD) increase in SHBG at baseline was inversely associated with the risk to develop hypertension at follow-up (OR = 0.74, 95% CI 0.58-0.95) in the fully adjusted model. Moreover, one SD increase in SHBG was associated with a decrease in mean SBP (delta = -1.5 mmHg, 95% CI - 2.2 to -0.8) and DBP (delta = - 1.0 mmHg, 95% CI - 1.5 to -0.4), after adjusting for covariates. CONCLUSION SHBG levels are inversely associated with development of hypertension and change in blood pressure levels independent of major risk factors.

Abstract
Epidemiological studies have associated plasma galectin-4 (Gal-4) levels with prevalent and incident diabetes, and with an increased risk of coronary artery disease. To date, data regarding possible associations between plasma Gal-4 and stroke are lacking. Using linear and logistic regression analyses, we tested Gal-4 association with prevalent stroke in a population-based cohort. Additionally, in mice fed a high-fat diet (HFD), we investigated whether plasma Gal-4 increases in response to ischemic stroke. Plasma Gal-4 was higher in subjects with prevalent ischemic stroke, and was associated with prevalent ischemic stroke (odds ratio 1.52; 95% confidence interval 1.01-2.30; p = 0.048) adjusted for age, sex, and covariates of cardiometabolic health. Plasma Gal-4 increased after experimental stroke in both controls and HFD-fed mice. HFD exposure was devoid of impact on Gal-4 levels. This study demonstrates higher plasma Gal-4 levels in both experimental stroke and in humans that experienced ischemic stroke.

Abstract
AIM To assess the hypothesis that low internal health locus of control (IHLC) and psychological distress (PD) are associated with insulin resistance. MATERIALS AND METHODS In 2002-2005, a random population sample of 2,816 men and women aged 30-74 years participated (76%) in two municipalities in southwestern Sweden. This study included 2,439 participants without previously known diabetes or cardiovascular disease. IHLC was measured by a global scale and PD was measured by the 12-item General Health Questionnaire. Insulin resistance was estimated using HOMA-ir. General linear models were used to estimate differences in HOMA-ir between groups with low IHLC, PD, and both low IHLC and PD, respectively. RESULTS Five per cent (n = 138) had both PD and low IHLC, 62 per cent of participants (n = 1509) had neither low IHLC nor PD, 18 per cent (n = 432) had PD, and 15 per cent (n = 360) low IHLC. Participants with both low IHLC and PD had significantly higher HOMA-ir than participants with neither low IHLC nor PD (Δ = 24.8%, 95%CI: 12.0-38.9), also in the fully adjusted model (Δ = 11.8%, 95%CI: 1.5-23.0). Participants with PD had significantly higher HOMA-ir (Δ = 12%, 95%CI: 5.7-18.7), but the significance was lost when BMI was included in the model (Δ = 5.3%, 95%CI:0.0-10.8). Similarly, participants with low IHLC had significantly higher HOMA-ir (Δ = 10.1%, 95%CI: 3.5-17.0) but the significance was lost in the fully adjusted model (Δ = 3.5%, 95%CI: -1.9-9.3). CONCLUSIONS Internal health locus of control (IHLC) and psychological distress (PD) were associated with insulin resistance. Especially individuals with both PD and low IHLC may need special attention.

Abstract
Abstract
Background
Globally, hypertension represents an enormous health issue as it is a major, yet modifiable risk factor for developing cardiovascular disease. Recently, chitinase-3-like protein 1 (CHI3L1) was shown to be positively associated with the incidence of hypertension among prehypertensive subjects, and variants of CHI3L1 gene were associated with both CHI3L1-levels and hypertension.
Purpose
To explore associations between prevalent hypertension and blood pressure, and 92 proteins with involvement in inflammation and cardiovascular disease.
Methods
Plasma samples from 1713 individuals from a Swedish population-based cohort (mean age 67.3±6.0 years; 28.9% women) were analysed with a proximity extension assay panel, consisting of 92 proteins. Prior to all analyses, subjects with prevalent cardiovascular disease, defined as having a history of prevalent coronary or stroke event, were excluded (n=189). Univariate logistic regression models were carried out exploring associations between each of the 92 proteins and prevalent hypertension, defined as systolic blood pressure ≥140 mmHg and/or a diastolic blood pressure ≥90 mmHg, or use of antihypertensive treatment (n=1168, 76.4%). Bonferroni-corrected significant associations between proteins and hypertension were further analysed using stepwise selection of covariates, namely age, body mass index, diabetes status, and cystatin C, in logistic regression models. Proteins with significant adjusted associations with prevalent hypertension were further analysed for associations with systolic and diastolic blood pressure individually in stepwise linear regression models. Complete data on all variables were available in 1527 subjects.
Results
Sixteen proteins were significantly associated with prevalent hypertension in univariate analyses. After adjustment, three proteins remained significantly associated with prevalent hypertension (i.e., CHI3L1, low-density lipoprotein receptor (LDL receptor) and tissue plasminogen activator (tPA); Table 1). In analyses of associations with systolic blood pressure, CHI3L1 and LDL receptor showed significant associations. In analyses of associations with diastolic blood pressure, CHI3L1, LDL receptor and tPA showed significant associations (Table 1).
Conclusions
Higher CHI3L1, tPA and LDL receptor levels were positively associated with prevalent hypertension after multivariable adjustment, among 1527 elderly subjects without established cardiovascular disease. Furthermore, higher CHI3L and LDL receptor levels were positively associated with mean systolic, as well as mean diastolic blood pressure in multivariable analyses.

Abstract
The aim was to explore differences in the development of eGFR in persisting prediabetic conditions. This prospective study including 1327 individuals showed that eGFR decreased more in individuals with persisting IGT than in individuals with persisting IFG. Repeating OGTT and monitoring eGFR might improve the risk estimation in prediabetes.

Galectin-4 levels in hospitalized versus non-hospitalized subjects with obesity: the Malmö Preventive Project. Cardiovasc Diabetol 2022; 21:125.

Abstract
BACKGROUND Obesity is strongly associated with the development of cardiovascular disease (CVD). However, the heterogenous nature of obesity in CVD-risk is still poorly understood. We aimed to explore novel CVD biomarkers and their possible association with presumed unhealthy obesity, defined as hospitalized subjects with obesity (HO). METHODS Ninety-two proteins associated with CVD were analyzed in 517 (mean age 67 ± 6 years; 33.7% women) individuals with obesity (BMI ≥30 kg/m2) from the Malmö Preventive Project cohort, using a proximity extension array technique from the Olink CVD III panel. Individuals with at least one recorded hospitalization for somatic disease prior to study baseline were defined as HO phenotypes. Associations between proteins and HO (n = 407) versus non-hospitalized subjects with obesity (NHO, n = 110), were analyzed using multivariable binary logistic regression, adjusted for traditional risk factors. RESULTS Of 92 analyzed unadjusted associations between biomarkers and HO, increased levels of two proteins were significant at a false discovery rate < 0.05: Galectin-4 (Gal-4) and insulin-like growth factor-binding protein 1 (IGFBP-1). When these two proteins were included in logistic regression analyses adjusted for age and sex, Gal-4 remained significant. Gal-4 was independently associated with the HO phenotype in multivariable logistic regression analysis (OR 1.72; CI95% 1.16-2.54). Post-hoc analysis revealed that this association was only present in the subpopulation with diabetes (OR 2.26; CI95% 1.25-4.07). However, an interaction analysis was performed, showing no significant interaction between Gal-4 and prevalent diabetes (p = 0.16). CONCLUSIONS In middle-aged and older individuals with obesity, increased Gal-4 levels were associated with a higher probability of HO. This association was only significant in subjects with diabetes only, further implying a role for Gal-4 in diabetes and its complications.

Abstract
CONTEXT Obesity seems to decrease levels of testosterone. It is still unknown what role inflammation plays in the secretion of testosterone in men. OBJECTIVE The objective is to study the association between levels of C-reactive protein and testosterone and its role in predicting biochemical hypogonadism in men. DESIGN This was a longitudinal observational study between 2002 and 2014 in Sweden. PATIENTS OR OTHER PARTICIPANTS At the first visit, a random population sample of 1400 men was included, and 645 men fulfilled a similar protocol at a 10-year follow-up visit. After exclusion, 625 men remained to be included in the final analyses. MAIN OUTCOME MEASURE(S) Serum concentrations of testosterone and C-reactive protein (CRP) were measured at both visits. Bioavailable testosterone was calculated. Biochemical hypogonadism was defined as total testosterone levels <8 nmol/L. RESULTS At the first visit and in the longitudinal analyses, a strong association was found between high levels of CRP and low levels of calculated bioavailable testosterone even after adjustments for age, waist-hip ratio, hypertension, smoking, type 2 diabetes, and leisuretime physical activity (B = -0.31, 95% CI -0.49 to -0.13, P = 0.001, B = -0.26, 95% CI -0.41 to -0.11, P = 0.001). Similarly, increase with one s. d. in CRP was associated with increased risk of having hypogonadism after adjustment in the final model (odds ratio (OR) 1.76, 95% CI 1.12-2.78, P = 0.015, OR 1.80, 95% CI 1.16-2.78, P =0.008). CONCLUSIONS In this representative cohort of men in southwestern Sweden, high levels of CRP were longitudinally associated with low concentrations of calculated bioavailable testosterone and increased risk of biochemical hypogonadism.

Abstract
Context It is uncertain which cardiovascular risk factors are associated with sex hormone levels in postmenopausal women. Objective This work aimed to investigate the association between cardiometabolic risk factors and sex hormones in a cross-sectional, observational population study. Methods In this Swedish population study, participants were physically examined from 2002 to 2004, and endogenous sex hormones were analyzed by liquid chromatography–tandem mass spectrometry. Women aged 55 years or older with estradiol levels below 20 pg/mL and not using any hormonal therapy were eligible for inclusion in the study (N = 146). Variable selection and bootstrap stability analyses were performed and linear regression models presented, with each of the 8 hormones as outcome variables. Results Body mass index (BMI) was positively associated with estradiol (β = 0.054, P < .001), but negatively associated with 17-α-hydroxyprogesterone (β = –0.023, P = .028). Waist-to-hip ratio (WHR) was negatively associated with dihydrotestosterone (β = –2.195, P = .002) and testosterone (β = –1.541, P = .004). The homeostatic model assessment of insulin resistance was positively associated with androstenedione (β = 0.071, P = .032), estradiol (β = 0.091, P = .009), estrone (β = 0.075, P = 0.009), and 17-α-hydroxyprogesterone (β = 0.157, P = .001). Age was positively associated with testosterone (β = 0.017, P = .042). C-reactive protein showed an inverse association with progesterone (β = –0.028, P = .037). Lower low-density lipoprotein cholesterol was associated with higher estradiol levels (β = –0.093, P = .049), whereas lower triglycerides were associated with higher concentrations of dihydrotestosterone (β = –0.208, P = .016). Conclusion In postmenopausal women, WHR was strongly inversely associated with androgens, while BMI was positively associated with estrogens.

Abstract
Background The vasoconstricting peptide endothelin-1 (ET-1) is associated with endothelial dysfunction. The aim of this paper was to investigate whether circulating ET-1 levels predicts chronic kidney disease (CKD) in a prospective population study. Methods In 2002–2005, 2816 participants (30–74 years) were randomly selected from two municipalities in South-Western Sweden and followed up in a representative sample of 1327 individuals after 10 years. Endothelin-1 levels were assessed at baseline. Outcome was defined as CKD stage 3 or above based on eGFR < 60 mL/min/1.73m2. Those 1314 participants with successful analysis of ET-1 were further analyzed using binary logistic regression. Results At follow-up, 51 (8%) men and 47 (7,8%) women had CKD stage 3 and above. Based on levels of ET-1 the population was divided into quintiles showing that women in the highest quintile (n = 132) had a significantly increased risk of developing CKD during the follow up period (OR = 2.54, 95% CI:1.19–5.45, p = 0.02) compared with the other quintiles (1–4). The association was borderline significant after adjusted for age, current smoking, alcohol consumption, hypertension, diabetes, BMI, high- sensitive CRP and LDL-cholesterol (OR = 2.25, 95% CI:0.97–5.24, p = 0.06). No significant differences were observed between quintiles of ET-1 and development of CKD in men (NS). Conclusions High levels of ET-1 are associated with development of CKD in women.

Abstract
BACKGROUND In a clinical trial 2009-2012, individuals with prediabetes were randomised to a lifestyle intervention (LI) focused on physical activity or care as usual (CAU), with the aim of reducing development of type 2 diabetes (T2DM). At study termination after three years, there was a significantly less of an increase in insulin resistance in LI compared with the CAU group. The aim of this extended follow-up was to investigate whether positive results concerning metabolic variables remained five years after study termination. METHOD All participants from the original study were contacted for a new follow-up with an oral glucose tolerance test, anthropometric measurements, blood pressure and blood samples. Questionnaires about lifestyle were completed. RESULTS A total of 69 of the original 123 participants were examined, and personal data for another five participants were collected from the medical charts (n = 74). The LI group showed a decrease in diastolic blood pressure (-4 mmHg, CI 95% 0.8-6.8, p = 0.014) and body weight (-3 kg, CI 95% 1.2-4.9, p = 0.002) since base-line. Weight loss in the LI group was significantly greater compared with weight loss in the CAU group (-3 kg, CI 0.1-5.9, p = 0.044). Insulin resistance markers and incident T2DM were similar among the groups. CONCLUSION Although without modifying the incidence of diabetes or the level of insulin resistance, a physical activity intervention may be used to induce sustainable weight change in subjects with prediabetes at the primary care level.

Effects of nutrition education using a food-based approach, carbohydrate counting or routine care in type 1 diabetes: 12 months prospective randomized trial. BMJ Open Diabetes Res Care 2021; 9:9/1/e001971. [PMID: 33789909 PMCID: PMC8016079 DOI: 10.1136/bmjdrc-2020-001971] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 02/24/2021] [Accepted: 03/14/2021] [Indexed: 11/03/2022] Open
Abstract
INTRODUCTION Evidence on the effects of structured nutrition education is weak in adults with type 1 diabetes mellitus (T1D) with moderately impaired glycemic control. Objective was to compare the effects of different types of nutrition education programs on glycemic control, cardiovascular risk factors, quality of life, diet quality and food choices in T1D. RESEARCH DESIGN AND METHODS A 12 months randomized controlled study conducted at nine diabetes specialist centers with three parallel arms: (i) a food-based approach (FBA) including foods with low glycemic index or (ii) carbohydrate counting (CC) according to today's standard practice or (iii) individual sessions according to routine care (RC). The primary end point was difference in glycated hemoglobin A1c (HbA1c) between groups at 12 months. RESULTS 159 patients were randomized (FBA: 51; CC: 52; RC: 55). Mean (SD) age 48.6 (12.0) years, 57.9% females and mean (SD) HbA1c level 63.9 (7.9) mmol/mol, 8% (0.7%). After 3 months, HbA1c improved in both FBA and CC compared with RC. However, there were no significant differences at 12 months in HbA1c; FBA versus RC (-0.4 mmol/mol (1.3), 0.04% (0.1%)), CC versus RC (-0.8 mmol/mol (1.2), 0.1% (0.1%)), FBA versus CC (0.4 mmol/mol (0.3), 0.04% (0.01%)). At 12 months, intake of legumes, nuts and vegetables was improved in FBA versus CC and RC. FBA also reported higher intake of monounsaturated and polyunsaturated fats compared with RC, and dietary fiber, monounsaturated and polyunsaturated fats compared with CC (all p values <0.05). There were no differences in blood pressure levels, lipids, body weight or quality of life. CONCLUSIONS Nutrition education using an FBA, CC or RC is equivalent in terms of HbA1c and cardiovascular risk factors in persons with T1D with moderately impaired glycemic control. An FBA had benefits regarding food choices compared with CC and RC.

Longitudinal association between leisure-time physical activity and vascular elasticity indices. BMC Cardiovasc Disord 2021; 21:99. [PMID: 33593279 PMCID: PMC7885232 DOI: 10.1186/s12872-021-01911-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Accepted: 12/28/2020] [Indexed: 11/10/2022] Open
Abstract
AIM We investigated the association between levels of leisure-time physical activity and vascular stiffness in a longitudinal observational study from a representative Swedish population. METHOD A total of 2816 randomly selected individuals were examined at visit 1 (2002-2005, Men = 1400). After a mean follow-up of 9.7 ± 1.4 years, a representative sample of 1327 of the original participants were re-examined at visit 2. After excluding subjects with hypertension at baseline, 761 participants were included in the longitudinal analyses. Leisure-time physical (LTPA) activity was self-reported and dichotomized as high or low (level 3, 4 and level 1, 2, respectively). Large Arterial Elasticity Index (LAEI) and Small Arterial Elasticity Index (SAEI) were measured using the HDI/Pulse Wave™ CR2000. Multivariable general linear models were used to investigate the differences in changes SAEI and LAEI based on LTPA levels. RESULTS At visit 1, and after adjustment for possible confounders, participants in the high LTPA group had better small artery elasticity (SAEI) (SAEI in low-level LTPA: 7.89 ± 0.11, SAEI in high-level LTPA: 8.32 ± 0.15, ΔSAEI: 0.42, CI: 0.07-0.78; p = 0.020). SAEI decreased between the two assessments (Visit 1: SAEI 8.01 ± 3.37 ml/mmHg; Δ SAEI: 1.4, CI 1.2-1.6, p < 0.001). Participants with a higher LTPA at visit 1 had significantly better SAEI at visit 2 (ΔSAEI: 0.44, CI 0.03-0.85, p = 0.037). No significant associations were observed between LAEI and LTPA after adjustments. CONCLUSIONS High LTPA predicted higher small arterial compliance at visit 2 suggesting that positive effects of LTPA on arterial elasticity persists over time.

C-reactive protein in traditional melanesians on Kitava. BMC Cardiovasc Disord 2020; 20:524. [PMID: 33334321 PMCID: PMC7745357 DOI: 10.1186/s12872-020-01812-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Accepted: 12/06/2020] [Indexed: 01/01/2023] Open
Abstract
Background Population-based levels of the chronic low-grade systemic inflammation biomarker, C-reactive protein (CRP), vary widely among traditional populations, despite their apparent absence of chronic conditions associated with chronic low-grade systemic inflammation, such as type 2 diabetes, metabolic syndrome and cardiovascular disease. We have previously reported an apparent absence of aforementioned conditions amongst the traditional Melanesian horticulturalists of Kitava, Trobriand Islands, Papua New Guinea. Our objective in this study was to clarify associations between chronic low-grade systemic inflammation and chronic cardiometabolic conditions by measuring CRP in a Kitava population sample. For comparison purposes, CRP was also measured in Swedish controls matched for age and gender.
Methods Fasting levels of serum CRP were measured cross-sectionally in ≥ 40-year-old Kitavans (N = 79) and Swedish controls (N = 83). Results CRP was lower for Kitavans compared to Swedish controls (Mdn 0.5 mg/L range 0.1—48 mg/L and Mdn 1.1 mg/L range 0.1—33 mg/L, respectively, r = .18 p = .02). Among Kitavans, there were small negative associations between lnCRP for CRP values < 10 and total, low-density lipoprotein (LDL) and non-high-density lipoprotein (non-HDL) cholesterol. Among Swedish controls, associations of lnCRP for CRP values < 10 were medium positive with weight, body mass index, waist circumference, hip circumference and waist-hip ratio and low positive with triglyceride, total cholesterol-HDL cholesterol ratio, triglyceride-HDL cholesterol ratio and serum insulin. Conclusions Chronic low-grade systemic inflammation, measured as CRP, was lower among Kitavans compared to Swedish controls, indicating a lower and average cardiovascular risk, respectively, for these populations.

Proteomic exploration of common pathophysiological pathways in diabetes and cardiovascular disease. ESC Heart Fail 2020; 7:4151-4158. [PMID: 33047884 PMCID: PMC7754972 DOI: 10.1002/ehf2.13036] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 08/07/2020] [Accepted: 09/15/2020] [Indexed: 12/31/2022] Open
Abstract
Aims The epidemiological association between diabetes and cardiovascular disease is well established, but the pathophysiological link is complex and multifactorial. We investigated seven proteins, previously linked to incident diabetes mellitus, and their association with cardiovascular disease and mortality. Methods and results Plasma samples from 1713 individuals from the Swedish population‐based Malmö Preventive Project (mean age 67.4 ± 6.0 years; 29.1% women) were analysed with a proximity extension assay panel. Seven proteins [scavenger receptor cysteine rich type 1 protein M130 (CD163), fatty acid‐binding protein 4 (FABP4), plasminogen activator inhibitor 1 (PAI), insulin‐like growth factor‐binding protein 2 (IGFB2), cathepsin D (CTSD), galectin‐4 (GAL4), and paraoxonase‐3 (PON3)] previously shown to be associated with incident diabetes were analysed for associations with all‐cause mortality (ACM), cardiovascular mortality (CVM), incident coronary events (CEs), and incident heart failure (HF). After exclusion of prevalent cases of respective outcome, proteins that met Bonferroni‐corrected significance were analysed in multivariable Cox regression models. Significant associations were identified between five proteins [GAL4 (hazard ratio; 95% confidence interval: 1.17–1.41), CTSD (1.15–1.37), CD163 (1.09–1.30), IGFBP2 (1.05–1.30), and FABP4 (1.04–1.29)] and ACM and four proteins [GAL4 (1.38–1.56), CTSD (1.14–1.43), CD163 (1.09–1.36), and IGFBP2 (1.03–1.35)] with CVM. Three proteins [GAL4 (1.14–1.57), CTSD (1.12–1.50), and FABP4 (1.05–1.55)] were significantly associated with incident CE and two [GAL4 (1.03–1.54) and CTSD (1.01–1.46)] were associated with incident HF after adjusting for traditional risk factors including N‐terminal pro‐brain natriuretic peptide. Conclusions In a general Swedish population, four proteins previously shown to be associated with diabetes were associated with ACM and CVM. Three proteins were associated with incident CE. Finally, GAL4 and CTSD displayed novel associations with incident HF and were the only proteins associated with all outcomes.

Abstract
BACKGROUND Middle-Eastern immigrants in Sweden are at increased risk for type 2 diabetes (T2D) and poor mental health. Physical activity not only prevents/delays onset of T2D but also shows favorable effects on mental health. However, the effects of a culturally adapted lifestyle intervention on mental health among Middle-Eastern immigrants have not been explored before. We aimed to study the effects of a randomized controlled, culturally adapted lifestyle intervention on anxiety and depression levels in diabetes-prone Iraqi immigrants. METHODS Participants (n = 96) were randomized to intervention group, IG (n = 50) or control group, CG (n = 46). The IG received seven group sessions addressing lifestyle change and the CG received treatment as usual. Montgomery-Åsberg Depression Rating Scale (MADRS-S) and Hospital Anxiety and Depression Scale (HADS) assessed mental health at start, mid (2 months) and end of the study (4 months). Proportional odds ratio (OR) model was used to study the effect of the intervention. RESULTS The odds of scoring lower on MADRS-S and HADS depression scale at visit 3 vs. baseline were higher in the IG compared to the CG (MADRS-S OR 5.9, 95% CI: 1.6-22.5; HADS OR 4.4, 95% CI: 0.9-20.3). The findings persisted after adjustment for age, sex, body mass index, time since migration, sedentary lifestyle and language spoken at home. Group differences were non-significant at visit 2 vs. baseline. CONCLUSION A culturally adapted lifestyle intervention addressing T2D prevention in Middle-Eastern immigrants has favorable effects on mental health. The effect was more pronounced at the 4 months than at 2 months follow-up, indicating beneficial effect of longer study duration. TRIAL REGISTRATION www.clinicaltrials.gov NCT01420198.

Abstract
Objective Atrial fibrillation (AF) is the most common arrhythmia and associated with increased morbidity and mortality. Its increasing prevalence calls for novel biomarkers to identify underlying pathophysiological mechanisms as well as patients at risk. Methods Plasma samples from 1694 individuals from the Swedish population-based Malmö Preventive Project (mean age 69.5 years; 29.3% female; mean follow-up time 9.7±3.1 years) were analysed with the Olink proximity extension assay CVD III panel consisting of 92 proteins to identify proteins associated with incident AF or atrial flutter, referred to as incident AF. Incident cases of AF (n=278) were retrieved by linkage to the registers. Participants were followed until the first episode of AF or until censoring by death or emigration. Bonferroni-corrected multivariable Cox regression models adjusted for known risk factors were used to explore possible associations of the 92 proteins and incidence of AF. Results Multivariable Cox regression analyses of 11 proteins associated with incident AF (mean follow-up time 9.7±3.1 years) after Bonferroni correction confirmed N-terminal pro-B-type natriuretic peptide (HR per 1 SD increment (95% CI) 1.80 (1.58 to 2.04); p=1.2×10-19) as risk marker of incident AF. Further, matrix metalloproteinase-2 (1.22 (1.07 to 1.39); p=0.002) and osteopontin (1.27 (1.12 to 1.44); p=2.7×10-4) were associated with incident AF at follow-up independently of traditional risk markers and NT-proBNP. Conclusion In a general Swedish population, we confirmed the well-known association of NT-proBNP with incident AF and also identified matrix metalloproteinase-2 and osteopontin as novel risk markers for incident AF, independently of traditional risk factors and NT-proBNP.

Abstract
AIM Previous studies have shown that individuals with impaired glucose tolerance (IGT) have lower self-rated health than normoglycaemic individuals. The aim of this study was to examine differences in self-rated health between individuals with IGT and those with impaired fasting glucose (IFG) and to consider the potentially mediating effect of physical activity. METHODS In 2002-2005, a total of 2816 individuals were randomly selected for a population-based study in Sweden. All participants performed an oral glucose tolerance test (OGTT). Fasting venous blood samples were drawn, and questionnaires concerning lifestyles were completed. Self-rated health (SRH) and leisure time physical activity (LTPA) were reported on a five-graded and four-graded scale, respectively. A total of 213 individuals with IGT and 129 with IFG were detected. RESULTS IGT, but not IFG, was associated with low self-rated health. The difference in self-rated health was seen particularly in men when adjusted for age and BMI (OR = 2.13, CI: 1.13-4.02, p = 0.020). The results became insignificant when including physical activity in the model (OR = 1.8, CI: 0.91-3.58, p = 0.094). CONCLUSION The low self-rated health adds further weight to the risk profile in men with IGT and stresses the importance of early detection and lifestyle interventions.

Abstract
Aims Although the epidemiological association between Type 2 diabetes and congestive heart failure (CHF) as well as cardiovascular disease (CVD) is well established, associations between diabetes‐related single‐nucleotide polymorphisms (SNPs), CHF, and CVD have been surprisingly inconclusive. Our aim is to examine if 43 diabetes‐related SNPs were associated with prevalent diastolic dysfunction assessed by echocardiography and incident CVD and/or CHF. Methods and results We genotyped 43 SNPs that previously reported genome‐wide significant associations with Type 2 diabetes, in 1444 subjects from the population‐based Malmö Preventive Project‐Re‐examination Study (MPP‐RES) (mean age 68 years; 29% women, 36% prevalent diabetes) (discovery cohort) and in 996 subjects from the VARA cohort (mean age 51 years, 52% women, 7% prevalent diabetes) (replication cohort). Multivariable logistic regression was assessed. Genetic variants that reached significant association with diastolic dysfunction in both cohorts were then analysed for association with incident CVD/CHF in a larger sample of the MPP‐RES cohort (3,407 cases and 11,776 controls, median follow up >30 years) using Cox regression analysis. A common variant at the HNF1B [major allele (T) coded, also the risk allele for diabetes] was the only SNP associated with increased risk of prevalent diastolic dysfunction in both the discovery [MPP‐RES; odds ratio (OR) 1.21, P = 0.024), and the replication cohort (VARA; OR 1.38, P = 0.042]. Cox regression analysis showed that carriers of the T‐allele of rs757210 had an increased risk of future CVD (HR 1.05, P = 0.042). No significant association was seen for incident CHF. Conclusions The diabetes susceptibility locus HNF1B is associated with prevalent diastolic dysfunction in two independent Swedish cohorts as well as incident cardiovascular disease.

Abstract
Aims: We aimed to investigate (a) the association between body mass index (BMI) and self-rated health (SRH) and (b) BMI's predicted value for SRH within a representative population in the Skaraborg Project. Methods: This was a longitudinal observational study. A random population of 2816 individuals were included in the study between 2002 and 2005, and a representative sample of these individuals were invited consecutively for a follow-up visit between 2012 and 2014. At follow-up, data from 1327 participants were collected concerning anthropometric variables, blood samples and validated questionnaires regarding lifestyle factors. Results: A significant inverse association was observed between BMI and SRH both at baseline and at follow-up, with all p-values for trend being ⩽0.001 in both men and women. This association was observed even after adjusting for confounders such as co-morbidity, age, sex, education, marital status and lifestyle factors. In addition, the longitudinal analyses showed that BMI at baseline was inversely associated with SRH at follow-up in both sexes (odds ratio (OR)=1.1, confidence interval (CI) 1.02-1.16, p=0.017 in men; and OR=1.1, CI 1.04-1.14, p=0.001 in women). These findings remained in participants whose weight increased (p=0.022) or was stable (p=0.004), while it was not seen in individuals who lost weight over the years (p=0.340). Conclusions: SRH is inversely associated with BMI in Swedish men and women. High BMI predicted low SRH from a longitudinal perspective, independent of co-morbidities, except for individuals who lost weight over the years. This knowledge emphasises the importance of an understanding and empathetic attitude towards these individuals.

Abstract
Abstract
Background
Although Azurocidin-1 (Azu-1), also known as heparin binding protein, has been associated with myocardial infarction, possible associations of Azu-1 with congestive heart failure (CHF) remains unknown. Here we tested the possible association of Azu-1 with prevalent diastolic dysfunction and/or incident CHF in a large Swedish prospective population based cohort.
Methods
Azu-1 was analyzed using the Proseek Multiplex CVD III panel in 1737 participants from a subsample of the population (mean age 67 years, 29% women) who underwent a complete echocardiographic examination. All biomarkers were logarithmized and standardized prior to statistical analysis.
Logistic and linear regression were adjusted for age, sex, BMI, diabetes, systolic and diastolic blood, anti-hypertensive treatment and subjects with an ejection fraction below 50% were excluded for the analysis of prevalent diastolic dysfunction and Azu-1. For the linear regression model, we used E/é ratio as a key functional variable in assessing diastolic function according to ESC 2016 Guidelines for Acute and Chronic Heart Failure. Furthermore, we dichotomized the E/é ratio at >13 in another logistic regression model. Finally, in line with ESC Guidelines 2016, we combined the key functional (E/é >13) and key structural (left ventricular mass index (LVMI) ≥115 g/m2 for males and ≥95 g/m2 for females) alterations for diastolic dysfunction and used this variable in both logistic regression for association with Azu-1 and for Cox regression analysis of incident CHF. 1439 subjects (938 cases with some degree of diastolic dysfunction and 501 controls) remained for the analysis.
For the analysis of incident CHF, Cox regression was used excluding subjects with ejection fraction below 50% and prevalent CHF and further adjusted for prevalent coronary disease on top of age, sex, BMI, diabetes, systolic and diastolic blood and anti-hypertensive treatment. 1,511 subjects (64 incident cases of CHF vs 1447 controls; median follow up time 8.9 years) remained.
Results
After adjustment for above mentioned risk factors, each 1 standard deviation (SD) of increase in Azu-1 was associated with any degree of prevalent diastolic dysfunction (odds ratio (OR) 1.13, p=0.048), E/é >13 OR 1.21, p=0.028 and for combined LVMI and E/é OR 1.17, p=0.015. In fully adjusted linear regression Azu-1 was associated with E/é with a β-coefficient of 0.056, p=0.018.
In a fully adjusted Cox regression models Azu-1 was associated with incident CHF (hazard ratio (HR) 1.32, p=0.025). As expected and as proof of concept E/é >13 and combined LVMI with E/é were also associated with incident CHF; HR 2.84, p<0.001 and HR 2.12, p=0.006, respectively.
Conclusion
An inflammatory mediator, Azurocidin-1, is associated with prevalent diastolic dysfunction, E/é, E/é combined with LVMI as well as incident congestive heart failure in a population-based cohort.

Abstract
Multiplex proteomic platforms provide excellent tools for investigating associations between multiple proteins and disease (e.g., diabetes) with possible prognostic, diagnostic, and therapeutic implications. In this study our aim was to explore novel pathophysiological pathways by examining 92 proteins and their association with incident diabetes in a population-based cohort (146 cases of diabetes versus 880 controls) followed over 8 years. After adjusting for traditional risk factors, we identified seven proteins associated with incident diabetes. Four proteins (Scavenger receptor cysteine rich type 1 protein M130, Fatty acid binding protein 4, Plasminogen activator inhibitor 1 and Insulin-like growth factor-binding protein 2) with a previously established association with incident diabetes and 3 proteins (Cathepsin D, Galectin-4, Paraoxonase type 3) with a novel association with incident diabetes. Galectin-4, with an increased risk of diabetes, and Paraoxonase type 3, with a decreased risk of diabetes, remained significantly associated with incident diabetes after adjusting for plasma glucose, implying a glucose independent association with diabetes.

Abstract
The objective of this study was to investigate whether there is a bidirectional association between testosterone concentrations and insulin resistance, in a prospective population study. A random population sample of 1400 men, aged 30-74, was examined in 2002-2005 in southwestern Sweden and followed up in 2012-2014 (N = 657). After excluding subjects without information on sex hormones and insulin resistance, 1282 men were included in the baseline study. Fasting measurements of plasma glucose, insulin and hormones were performed. Insulin resistance was defined using HOMA-Ir. Mean age at baseline was 47.3 ± 11.4 years. From the follow-up survey 546 men were included, mean age 57.7 ± 11.6 years. Low concentrations of total testosterone at baseline were significantly associated with high logHOMA-Ir at follow-up in a multivariable model including age, waist-hip ratio, physical activity, alcohol intake, smoking, LDL, CRP, hypertension, diabetes and logHOMA-Ir at baseline as covariates (β = -0.096, P = 0.006). Similar results were observed for bioavailable testosterone. Men within the lowest quartile of total testosterone at baseline had significantly higher logHOMA-Ir at follow-up than other quartiles (Q1 vs Q2 P = 0.008, Q1 vs Q3 P = 0.001, Q1 vs Q4 P = 0.052). Multivariable analysis of the impact of insulin resistance at baseline on testosterone levels at follow-up revealed no significant associations regarding testosterone concentrations (β = -0.003, P = 0.928) or bioavailable testosterone (β = -0.006, P = 0.873), when adjusting for baseline concentrations of total testosterone, age, waist-hip-ratio, LDL, CRP, physical activity, alcohol intake, smoking, hypertension and diabetes. Low testosterone concentrations at baseline predicted higher insulin resistance at follow-up, but high insulin resistance at baseline could not predict low testosterone at follow-up.

Abstract
The evidence concerning how posture influences blood pressure is not consistent. The aim of this cross-sectional study was to consider the clinical and epidemiological implications of blood pressure measured in seated versus supine position, and to investigate the impact of age, sex, body mass index (BMI), and diabetes on these differences.This study included 1298 individuals (mean age 58.6 ± 11.8 years) from the Vara-Skövde cohort at the 10 years' follow-up visit in 2014. Physical examination included blood pressure measurements in seated and supine position. Self-reported information on diabetes status, hypertension, ongoing medication, leisure time physical activity, and smoking habits were obtained. Linear regression models accounted for differences in age, sex, BMI, and known diabetes.Both systolic and diastolic blood pressure were significantly higher in the seated position [1.2 mm Hg, P < .001, 95% confidence interval (95% CI) 0.79-1.54 and 4.2 mm Hg, P < .001, 95% CI 4.08-4.71, respectively]. The prevalence of high blood pressure in seated position was higher (19.9%) than in supine position (13.5%). Linear regression analysis showed that age (β = -0.215, P < .001) and diabetes (β = -0.072, P = .012) were associated with smaller differences in postural diastolic blood pressure and BMI (β = 0.124, P < .001) with greater difference.This study showed substantial postural differences in blood pressures measured in office. Measuring blood pressure in the supine position shows lower blood pressure readings when compared with the seated position. Clinicians should be aware of how age, BMI, and diabetes influence these differences.

Self-knowledge of HbA1c in people with Type 2 Diabetes Mellitus and its association with glycaemic control. Prim Care Diabetes 2017; 11:414-420. [PMID: 28684227 DOI: 10.1016/j.pcd.2017.03.011] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2016] [Revised: 02/28/2017] [Accepted: 03/15/2017] [Indexed: 01/13/2023]
Abstract
OBJECTIVE The aim of this study was to evaluate the prevalence of accurate self-knowledge of a patient's own HbA1c level (HbA1cSK), as a component of structural education (University Hospital's of Leicester (UHL), 2013) and its association with glycaemic control. METHODS Data from the GUIDANCE study, a cross-sectional study involving 7597 participants from eight European countries was used. HbA1cSK was evaluated and compared with laboratory measured HbA1c levels (HbA1cLAB), which represented the measure of glycaemic control. Accuracy of the self-reported HbA1c was evaluated by using agreement statistical methods. RESULTS The prevalence of HbA1cSK was 49.4%. Within this group, 78.3% of the participants had accurately reported HbA1cSK. There was good level of agreement between HbA1cSK and HbA1cLAB (intra-class correlation statistic=0.84, p<0.0001). Participants with accurately reported HbA1cSK were found to have a statistically significantly lower HbA1cLAB compared to participants with inaccurately reported HbA1cSK (7.0% versus 7.3%, p<0.001). CONCLUSION Nearly half of the patients had self-knowledge of their own HbA1c level. Moreover, the participants with accurately reported HbA1cSK were found to have associated better glycaemic control.

Abstract
CONTEXT Diabetes and hypertension coexist in 40%-60% of individuals with type 2 diabetes. The coexistence of these two conditions is associated with increased risk of retinopathy, nephropathy and cardiovascular disease. OBJECTIVE To investigate the prevalence of primary aldosteronism (PA) in a general cohort of persons with type 2 diabetes. DESIGN Cross-sectional study involving six diabetes outpatient clinics in Sweden. PATIENTS were enrolled individuals with type 2 diabetes between February 2008 and December 2013. MEASUREMENTS Plasma aldosterone concentrations (PAC pmol/L) and direct renin concentrations (DRC mIU/L) were measured. Patients with increased aldosterone renin ratios (ARR) >65 were further evaluated for PA. RESULTS Of 578 consecutively screened patients with type 2 diabetes, 27 were treated with mineralocorticoid receptor antagonists (MRA) and potassium-sparing diuretics not further evaluated. Among the remaining 551 patients, 38 had increased ARR, including 22 who were clinically indicated for PA tests and 16 who were not further evaluated due to severe comorbidities and old age. There were five (0.93%) patients with confirmed PA after computerized tomography and adrenal venous sampling. Patients with PA had higher systolic blood pressure (P=.032) and lower potassium levels (P=.027) than those without PA. No significant association was found between plasma aldosterone and diabetic complications. CONCLUSIONS The prevalence of PA in an unselected cohort of patients with type 2 diabetes is relatively low, and measures of plasma aldosterone are not strong risk factors for micro- and macrovascular diabetic complications.

Abstract
OBJECTIVE Internet-delivered cognitive behavioral therapy (ICBT) is recommended as an efficient treatment alternative for depression in primary care. However, only few previous studies have been conducted at primary care centers (PCCs). We evaluated long-term effects of ICBT treatment for depression compared to treatment as usual (TAU) in primary care settings. DESIGN Randomized controlled trial. SETTING Patients were enrolled at16 PCCs in south-west Sweden. PARTICIPANTS Patients attending PCCs and diagnosed with depression (n = 90). INTERVENTIONS Patients were assessed by a primary care psychologist/psychotherapist and randomized to ICBT or TAU. The ICBT included an ICBT program consisting of seven modules and weekly therapist e-mail or telephone support during the 3-month treatment period. MAIN OUTCOME MEASURES Questionnaires on depressive symptoms (BDI-II), quality of life (EQ-5D) and psychological distress (GHQ-12) were administered at baseline, with follow-ups at 3, 6 and 12 months. Antidepressants and sedatives use, sick leave and PCC contacts were registered. RESULTS Intra-individual change in depressive symptoms did not differ between the ICBT group and the TAU group during the treatment period or across the follow-up periods. At 3-month follow-up, significantly fewer patients in ICBT were on antidepressants. However, the difference leveled out at later follow-ups. There were no differences between the groups concerning psychological distress, sick leave or quality of life, except for a larger improvement in quality of life in the TAU group during the 0- to 6-month period. CONCLUSIONS ICBT with weekly minimal therapist support in primary care can be equally effective as TAU among depressed patients also over a 12-month period. CLINICAL TRIAL REGISTRATION The trial was registered in the Swedish Registry, researchweb.org, ID number 30511.

Is there evidence of potential overtreatment of glycaemia in elderly people with type 2 diabetes? Data from the GUIDANCE study. Acta Diabetol 2017; 54:209-214. [PMID: 27837286 DOI: 10.1007/s00592-016-0939-9] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Accepted: 11/01/2016] [Indexed: 02/05/2023]
Abstract
AIMS We used data from the GUIDANCE Study to determine the care of people with type 2 diabetes according to age and accompanying cardiovascular diseases and to assess indicators of overtreatment of glycaemia. METHODS The GUIDANCE study was a retrospective, cross-sectional study from 2009-2010 based on the records of 7597 people in France, Belgium, Italy, the Netherlands, Sweden, UK, Ireland and Germany. We analysed the level of metabolic control achieved and blood glucose-lowering medication used in different age groups and in relation to accompanying diseases. RESULTS 4.459 patients (59.1%) were 65 years or older. Their HbA1c levels were similar to those with <65 years. 44.7% of patients ≥65 years had an HbA1c ≤7% (53 mmol/mol) and were treated with insulin or sulfonylureas, and 27.1% of them had ischaemic heart disease or congestive heart failure. Significantly more patients with heart disease had HbA1c values ≤7% (53 mmol/mol) and were treated more often with insulin or sulfonylureas compared to patients of the same age without heart disease. CONCLUSIONS Most patients were treated according to guidelines valid at the time this large international patient sample was surveyed. Older and younger patients were at a similar level of metabolic control, and almost half of the patients with an age of ≥65 years and treated with insulin or sulfonylurea had HbA1c levels below the target range (≤7%) for younger patients. However, these patients have an increased risk of severe hypoglycaemic events with potentially dangerous complications, particularly in those with cardiovascular diseases.

Effects of a culturally adapted lifestyle intervention on cardio-metabolic outcomes: a randomized controlled trial in Iraqi immigrants to Sweden at high risk for Type 2 diabetes. Metabolism 2017; 66:1-13. [PMID: 27923444 DOI: 10.1016/j.metabol.2016.10.001] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Revised: 09/16/2016] [Accepted: 10/02/2016] [Indexed: 12/23/2022]
Abstract
BACKGROUND AND AIMS Middle-Eastern immigrants constitute a growing proportion of the Swedish population and are at high risk for Type 2 diabetes. This calls for a more proactive preventive approach for dealing with diabetes risk in this target group. The aim was to test the effect of a culturally adapted lifestyle intervention programme on changes in lifestyle habits and cardio-metabolic outcomes comparing an intervention group with a control group receiving usual care. METHODS Citizens of Malmö, Sweden born in Iraq and at high risk for Type 2 diabetes (n=636) were invited. Participation rate was 15.1%. In all, 96 participants were randomized to the intervention group (n=50) or to the control group (n=46). The intervention group was offered seven group sessions addressing healthy diet and physical activity including one cooking class. Changes in body weight, physical activity levels and cardio-metabolic outcomes were evaluated using linear mixed-effects models. RESULTS The mean follow-up time was 3.9 and 3.5months in the intervention and control groups, respectively. The drop-out rate from baseline to the last visit was 30.0% in the intervention group (n=15) and 30.4% in the control group (n=14). The mean insulin sensitivity index increased significantly at follow-up in the intervention group compared to the control group (10.9% per month, p=0.005). The intervention group also reached a significant reduction in body weight (0.4% per month, p=0.004), body mass index (0.4% per month, p=0.004) and LDL-cholesterol (2.1% per month, p=0.036) compared to the control group. In total, 14.3% in the intervention group reached the goal to lose ≥5% of body weight versus none in the control group. CONCLUSIONS This culturally adapted lifestyle intervention programme shows a beneficial effect on insulin action, body weight reduction, as well as LDL-cholesterol reduction, in Middle-Eastern immigrants. The programme adapted to resources in primary health care provides tools for improved primary prevention and reduced cardio-metabolic risk in this high-risk group for Type 2 diabetes.

Clinical characteristics of asymptomatic left ventricular diastolic dysfunction and its association with self-rated health and N-terminal B-type natriuretic peptide: a cross-sectional study. ESC Heart Fail 2016; 3:205-211. [PMID: 27818785 PMCID: PMC5071719 DOI: 10.1002/ehf2.12090] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2015] [Revised: 11/30/2015] [Accepted: 02/16/2016] [Indexed: 11/27/2022] Open
Abstract
Aims Left ventricular hypertrophy, obesity, hypertension, and N‐terminal B‐type natriuretic peptide (Nt‐proBNP) predict left ventricular diastolic dysfunction with preserved systolic function (DD‐PSF). Self‐rated health (SRH) is shown to be associated with chronic diseases, but the association of SRH with DD‐PSF is unclear. In light of the clinical implications of DD‐PSF, the following goals are of considerable importance: (1) to determine the role of SRH in patients with DD‐PSF in the general population and (2) to study the association between Nt‐proBNP and DD‐PSF. Methods and results The current study is a cross‐sectional study conducted on a random sampling of a rural population. Individuals 30–75 years of age were consecutively subjected to conventional echocardiography and tissue velocity imaging. Data were collected on 500 (48%) men and 538 (52%) women (n = 1038). DD‐PSF was the main outcome, and SRH and Nt‐proBNP were the primary indicators. Diabetes mellitus, hypertension, and obesity were accounted for as major confounders of the association with SRH. DD‐PSF was identified in 137 individuals, namely, 79 men (15.8%) and 58 women (10.8%). In a multivariate regression model, SRH (OR 2.95; 95% CI 1.02–8.57) and Nt‐proBNP (quartile 4 vs. quartile 1 OR 4.23; 95% CI 1.74–10.26) were both independently associated with DD‐PSF. Conclusions SRH, evaluated based on a descriptive question on general health, should be included in the diagnostic process of DD‐PSF. In agreement with previous studies, our study confirms that Nt‐proBNP is a major indicator of DD‐PSF.

Abstract
BACKGROUND We here study antibodies against phosphorylcholine (anti-PC) which we reported to be inversely associated with atherosclerosis, cardiovascular disease (CVD), and autoimmune conditions. In previous studies, we determined that this inverse association is more pronounced at low levels with high risk and at high levels, with decreased risk. We compare individuals from Kitava, New Guinea (with low risk of these conditions), with Swedish controls. METHODS We studied a group of 178 individuals from Kitava (age 20-86), and compared those above age 40 (n = 108) with a group of age- and sex-matched individuals from a population based cohort in Sweden (n = 108). Traditional risk factors for CVD and fatty acids were determined. IgM, IgG, and IgA anti-PC were tested by enzyme-linked immunosorbent assay (ELISA). RESULTS All anti-PC measures were significantly lower among Swedish controls as compared to Kitavans (p < 0.001), independent of traditional risk factors. Having low levels of anti-PC, defined as below 25th percentile of values among Swedish controls, was associated with this cohort after adjustment for other risk factors (OR 5.7, 95% CI 2.2-14.7 for IgM; OR 31.7, 95% CI 3.9-252 for IgA; and OR 11.1, 95% CI 2.4-51 for IgG). CONCLUSIONS PC is highly exposed on microorganisms and helminths (common on Kitava) exposing much PC which humans and hominids may have been exposed to for millions of years. We propose that low anti-PC levels in the developed world could be a new aspect of the hygiene hypothesis, generating a pro-inflammatory and pro-atherosclerotic state.

A lifestyle intervention in primary care prevents deterioration of insulin resistance in patients with impaired glucose tolerance: A randomised controlled trial. Scand J Public Health 2016; 44:718-725.

Abstract
Aims: We hypothesised that the expected increase in insulin resistance over three years’ time in individuals with impaired glucose tolerance (IGT) and/or impaired fasting glucose could be attenuated by an intervention with focus on physical activity in ordinary primary care. Methods: We conducted a randomised controlled trial with 96 participants over three years. Examination of the participants included anthropometric measures, blood pressure, body weight and height, blood samples, an oral glucose tolerance test, and questionnaires about diet and lifestyle. The study subjects were randomised to either an intense intervention with information, group sessions, referral to physical activity and a step-counter ( n = 31), a less intense intervention without the group sessions ( n = 35), or care as usual group (CAUG) ( n = 30). Differences between the groups were analysed with general linear models adjusted for age, gender, baseline values and time in the intervention. Results: Individual insulin resistance increased in the CAUG. Due to having a similar effect, we combined the two intervention groups into a combined intervention group (CIG; n = 66) in the analyses. In individuals with IGT, the increase in the homeostatic model assessment-insulin resistance differed significantly between those in the CAUG and the CIG (Δ = 0.8; CI: 0.1–1.6; p = 0.034). Likewise, diastolic blood pressure decreased more in the CIG than in the CAUG (Δ = 5.1; CI: 0.1–10.0; p = 0.047). A total of 17 individuals developed Type 2 diabetes, 23% were in the CIG and 33% in the CAUG; so there was a 32% reduced risk in the intervention group. Conclusions: A lifestyle intervention focused on physical activity is feasible in ordinary primary care and prevents deterioration in insulin sensitivity in individuals with IGT over a three-year period.

Abstract
OBJECTIVES Inflammation is a well-established risk factor for the development of coronary artery disease (CAD) and acute coronary syndrome (ACS). However, less is known about its influence on the outcome of ACS. The aim of this study was to determine if blood biomarkers of inflammation were associated specifically with acute myocardial infarction (MI) or unstable angina (UA) in patients with ACS. DESIGN Cross-sectional study. SETTING Patients admitted to the coronary care unit, via the emergency room, at a central county hospital over a 4-year period (1992-1996). PARTICIPANTS In a substudy of Carlscrona Heart Attack Prognosis Study (CHAPS) of 5292 patients admitted to the coronary care unit, we identified 908 patients aged 30-74 years, who at discharge had received the diagnosis of either MI (527) or UA (381). MAIN OUTCOME MEASURES MI or UA, based on the diagnosis set at discharge from hospital. RESULTS When adjusted for smoking, age, sex and duration of chest pain, concentrations of plasma biomarkers of inflammation (high-sensitivity C reactive protein>2 mg/L (OR=1.40 (1.00 to 1.96) and fibrinogen (p for trend=0.035)) analysed at admission were found to be associated with MI over UA, in an event of ACS. A strong significant association with MI over UA was found for blood cell markers of inflammation, that is, counts of neutrophils (p for trend<0.001), monocytes (p for trend<0.001) and thrombocytes (p for trend=0.021), while lymphocyte count showed no association. Interestingly, eosinophil count (p for trend=0.003) was found to be significantly lower in patients with MI compared to those with UA. CONCLUSIONS Our results show that, in patients with ACS, the blood cell profile and degree of inflammation at admission was associated with the outcome. Furthermore, our data suggest that a pre-existing low-grade inflammation may dispose towards MI over UA.

Abstract
BACKGROUND A set of core diabetes indicators were identified in a clinical review of current evidence for the EUBIROD project. In order to allow accurate comparisons of diabetes indicators, a standardised currency for data storage and aggregation was required. We aimed to define a robust European data dictionary with appropriate clinical definitions that can be used to analyse diabetes outcomes and provide the foundation for data collection from existing electronic health records for diabetes. METHODS Existing clinical datasets used by 15 partner institutions across Europe were collated and common data items analysed for consistency in terms of recording, data definition and units of measurement. Where necessary, data mappings and algorithms were specified in order to allow partners to meet the standard definitions. A series of descriptive elements were created to document metadata for each data item, including recording, consistency, completeness and quality. RESULTS While datasets varied in terms of consistency, it was possible to create a common standard that could be used by all. The minimum dataset defined 53 data items that were classified according to their feasibility and validity. Mappings and standardised definitions were used to create an electronic directory for diabetes care, providing the foundation for the EUBIROD data analysis repository, also used to implement the diabetes registry and model of care for Cyprus. CONCLUSIONS The development of data dictionaries and standards can be used to improve the quality and comparability of health information. A data dictionary has been developed to be compatible with other existing data sources for diabetes, within and beyond Europe.

Abstract
BACKGROUND The vasoconstricting peptide endothelin-1 has been proposed to be a marker of cardiovascular disease. Our aim was to investigate whether circulating endothelin-1 levels predict coronary heart disease (CHD) in Sweden. METHODS In 2002-2005, 2816 adult participants (30-74 years) were randomly selected from two municipalities in south-western Sweden. Cardiovascular risk factors and endothelin-1 levels were assessed at baseline, and incident CHD was followed-up in all participants through 2011. After exclusion of 50 participants due to known CHD at baseline and 21 participants because of unsuccessful analysis of endothelin-1, 2745 participants were included in the study. In total, 72 CHD events (52 in men and 20 in women) were registered during the follow-up time. RESULTS We showed that baseline circulating endothelin-1 levels were higher in women with incident CHD than in women without CHD (3.2 pg/ml, SE: 0.36 vs 2.4 pg/ml, SE: 0.03, p = 0.003) whereas this difference was not observed in men (2.3 pg/ml, SE: 0.16 vs 2.3 pg/ml, SE: 0.04, p = 0.828). An age-adjusted Cox proportional regression analysis showed an enhanced risk of CHD with increasing baseline endothelin-1 levels in women (hazard ratio (HR) = 1.51, 95 % CI = 1.1-2.1, p = 0.015) but not in men (HR = 0.98, 95 % CI = 0.8-1.2, p = 0.854). Furthermore, the predictive value of endothelin-1 for incident CHD in women was still significant after adjustments for age, HOMA-IR, apolipoprotein (apo)B/apoA1 and smoking (HR = 1.53, CI = 1.1-1.2, p = 0.024). CONCLUSION Circulating endothelin-1 levels may predict CHD in women.

Abstract
AIM To evaluate the utility of three short questions (the Skövde Form) combined with a random plasma glucose, and HbA1c as alternative tools for detection of individuals with impaired glucose metabolism (IGM), and particularly impaired glucose tolerance (IGT). METHODS Three questions concerning BMI ≥ 25 kg/m(2), heredity for type 2 diabetes, and known hypertension were asked in a random population of 573 individuals. All with two positive answers or one positive answer and a random plasma glucose > 7.2 mmol/l were invited for an oral glucose tolerance test and an HbA1c examination. FINDRISC was completed for comparison. RESULTS The positive predictive value (PPV) for IGM, using the Skövde Form, was 31% while sensitivity and specificity were 59% and 73%, respectively. Corresponding values for IGT were 11%, 50% and 69%. Using HbA1c ≥ 42 mmol/mol, the PPV for IGM was 64% while sensitivity and specificity were 28% and 97%, respectively. The corresponding values for IGT were 15%, 16% and 94%. CONCLUSION The Skövde Form combined with a random plasma glucose may be used as an alternative tool for detection of individuals with IGM and IGT in particular. HbA1c may be used to identify individuals with type 2 diabetes but fails to detect most individuals with prediabetes.

Abstract
BACKGROUND The aim of the present study was to investigate the associations between endogenous testosterone concentrations and the incidence of acute myocardial infarction (AMI) in men and women with and without type 2 diabetes. METHODS The study comprised 1109 subjects ≥40 years of age (mean age 62 ± 12 years) participating in a baseline survey in Sweden in 1993-94. Information about smoking habits and physical activity was obtained using validated questionnaires. Serum concentrations of testosterone and sex hormone-binding globulin (SHBG) were obtained using radioimmunoassay. Diagnosis of type 2 diabetes was based on WHO's 1985 criteria. Individual patient information on incident AMI was ascertained by record linkage with national inpatient and mortality registers from baseline through 2011. RESULTS The prevalence of type 2 diabetes at baseline was 10.0% in men and 7.5% in women. During a mean follow-up of 14.1 years (±5.3), there were 74 events of AMI in men and 58 in women. In age-adjusted Cox models, a significant inverse association between concentrations of testosterone and AMI-morbidity was found in men with type 2 diabetes (HR = 0.86 CI (0.75-0.98)). In a final model also including waist-to-hip ratio, systolic blood pressure, total cholesterol and active smoking, the association still remained statistically significant (HR = 0.754 CI (0.61-0.92)). CONCLUSION Low concentrations of testosterone predicted AMI in men with type 2 diabetes independent of other risk factors. Trials with testosterone investigating the effect regarding cardiovascular outcome are still lacking. Future trials in this field should take into account a modification effect of diabetes.

Misreporting and misclassification: implications for socioeconomic disparities in body-mass index and obesity. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2015; 16:5-20. [PMID: 24363175 PMCID: PMC4286627 DOI: 10.1007/s10198-013-0545-5] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/04/2013] [Accepted: 11/20/2013] [Indexed: 06/03/2023]
Abstract
Body-mass index (BMI) has become the standard proxy for obesity in social science research. This study deals with the potential problems related to, first, relying on self-reported weight and height to calculate BMI (misreporting), and, second, the concern that BMI is a deficient measure of body fat (misclassification). Using a regional Swedish sample, we analyze whether socioeconomic disparities in BMI are biased because of misreporting, and whether socioeconomic disparities in the risk of obesity are sensitive to whether BMI or waist circumference is used to define obesity. Education and income are used as socioeconomic indicators. The overall conclusion is that misreporting and misclassification may indeed matter for estimated educational and income disparities in BMI and obesity. In the misreporting part we find that women with higher education misreport less than those with lower education, leading to underestimation of the education disparity when using self-reported information. In the misclassification part we find that the probability of being misclassified decreases with income, for both men and women. Among women, the consequence is a steeper income gradient when obesity is defined using waist circumference instead of BMI. Among men the income gradient is statistically insignificant irrespective of how obesity is defined, but when estimating the probability of obesity defined by waist circumference, an educational gradient, which is not present when classifying men using BMI, arises.

A family history of diabetes determines poorer glycaemic control and younger age of diabetes onset in immigrants from the Middle East compared with native Swedes. DIABETES & METABOLISM 2014; 41:45-54. [PMID: 25284578 DOI: 10.1016/j.diabet.2014.08.003] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2014] [Revised: 08/20/2014] [Accepted: 08/22/2014] [Indexed: 11/15/2022]
Abstract
AIMS Immigrant populations from the Middle East develop diabetes earlier than indigenous European populations; however, the underlying etiology is poorly understood. This study looked at the risk factors associated with early diabetes onset and, in non-diabetics, glycaemic control in immigrants from Iraq compared with native Swedes. METHODS This cross-sectional population-based study comprised 1398 Iraqi immigrants and 757 Swedes (ages 30-75years) residing in the same area of Malmö, Sweden. Outcomes were age at diabetes onset and glycaemic control (HbA1c) as assessed by Cox proportional hazards and linear regression, respectively. RESULTS In Iraqis vs Swedes, clustering in the family history (in two or more relatives) was more prevalent (23.2% vs 3.6%, P<0.001) and diabetes onset occurred earlier (47.6years vs 53.4years, P=0.001). Having an Iraqi background independently raised the hazard ratio (HR) for diabetes onset. Diabetes risk due to family history was augmented by obesity, with the highest HRs observed in obese participants with clustering in the family history (HR: 5.1, 95% CI: 3.2-8.2) after adjusting for country of birth and gender. In participants without previously diagnosed diabetes (Iraqis: n=1270; Swedes: n=728), HbA1c levels were slightly higher in Iraqis than in Swedes (4.5% vs 4.4%, P=0.038). This difference was explained primarily by clustering in the family history rather than age, obesity, lifestyle or socioeconomic status. CONCLUSION The study shows that the greater predisposition to diabetes in Middle Eastern immigrants may be explained by a more extensive family history of the disorder; clinical interventions tailored to Middle Eastern immigrants with such a family history are thus warranted.

Ethnicity is an independent risk indicator when estimating diabetes risk with FINDRISC scores: a cross sectional study comparing immigrants from the Middle East and native Swedes. Prim Care Diabetes 2014; 8:231-238. [PMID: 24472421 DOI: 10.1016/j.pcd.2014.01.002] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2013] [Revised: 12/20/2013] [Accepted: 01/03/2014] [Indexed: 12/28/2022]
Abstract
AIMS This study sought to compare type 2 diabetes (T2D) risk indicators in Iraqi immigrants with those in ethnic Swedes living in southern Sweden. METHODS Population-based, cross-sectional cohort study of men and women, aged 30-75 years, born in Iraq or Sweden conducted in 2010-2012 in Malmö, Sweden. A 75g oral glucose tolerance test was performed and sociodemographic and lifestyle data were collected. T2D risk was assessed by the Finnish Diabetes Risk Score (FINDRISC). RESULTS In Iraqi versus Swedish participants, T2D was twice as prevalent (11.6 vs. 5.8%, p<0.001). A large proportion of the excess T2D risk was attributable to larger waist circumference and first-degree family history of diabetes. However, Iraqi ethnicity was a risk factor for T2D independently of other FINDRISC factors (odds ratio (OR) 2.5, 95% CI 1.6-3.9). The FINDRISC algorithm predicted that more Iraqis than Swedes (16.2 vs. 12.3%, p<0.001) will develop T2D within the next decade. The total annual costs for excess T2D risk in Iraqis are estimated to exceed 2.3 million euros in 2005, not accounting for worse quality of life. CONCLUSIONS Our study suggests that Middle Eastern ethnicity should be considered an independent risk indicator for diabetes. Accordingly, the implementation of culturally tailored prevention programs may be warranted.

The influence of smoking and impaired glucose homoeostasis on the outcome in patients presenting with an acute coronary syndrome: a cross-sectional study. BMJ Open 2014; 4:e005077.

Abstract
OBJECTIVES Smoking, diabetes, male sex, hypercholesterolaemia and hypertension are well-established risk factors for the development of coronary artery disease (CAD). However, less is known about their role in influencing the outcome in the event of an acute coronary syndrome (ACS). The aim of this study was to determine if these risk factors are associated specifically with acute myocardial infarction (MI) or unstable angina (UA) in patients with suspected ACS. DESIGN Cross-sectional study. SETTING Patients admitted to the coronary care unit, via the emergency room, at a central county hospital over a 4-year period (1992-1996). PARTICIPANTS From 5292 patients admitted to the coronary care unit, 908 patients aged 30-74 years were selected, who at discharge had received the diagnosis of either MI (527) or UA (381). A control group consisted of 948 patients aged 30-74 years in whom a diagnosis of ACS was excluded. MAIN OUTCOME MEASURES MI or UA. RESULTS Current smoking (OR 2.42 (1.61 to 3.62)), impaired glucose homoeostasis defined as glycated haemoglobin ≥5.5% + blood glucose ≥7.5 mM (OR 1.78 (1.19 to 2.67)) and male sex (OR 1.71 (1.21 to 2.40)) were significant factors predisposing to MI over UA, in the event of an ACS. Compared with the non-ACS group, impaired glucose homoeostasis, male sex, cholesterol level and age were significantly associated with development of an ACS (MI and UA). Interestingly, smoking was significantly associated with MI (OR 2.00 (1.32 to 3.02)), but not UA. CONCLUSIONS Smoking or impaired glucose homoeostasis is an acquired risk factor for a severe ACS outcome in patients with CAD. Importantly, smoking was not associated with UA, suggesting that it is not a risk factor for all clinical manifestations of CAD, but its influence is important mainly in the acute stages of ACS. Thus, on a diagnosis of CAD, the cessation of smoking and management of glucose homoeostasis are of upmost importance to avoid severe subsequent ACS consequences.

Feasibility of a randomized controlled intervention with physical activity in participants with impaired glucose tolerance recruited by FINDRISC: A pilot study. Scand J Public Health 2014; 42:463-70.

Abstract
Background: This study aimed to explore the feasibility and effect of an intervention in clinical practice with isolated physical activity in individuals with IGT, recruited by the FINDRISC questionnaire. Methods: The questionnaire was sent to a population of 9734 individuals, 35–75 years old, in Sweden. Those with a risk score ≥15 were encouraged to perform an oral glucose tolerance test. Individuals with IGT were invited to participate in a randomized controlled trial with a focus on physical activity. The participants were allocated to one of three arms; basic intervention, intensive intervention or to care as usual. A total of 52 individuals were carefully examined and questionnaires about diet and lifestyle were completed at baseline and after one year. All analyses were adjusted for differences in age and sex, and calorie intake when relevant. Results :The prevalence of chronic diseases in the study population was high, creating considerable difficulties in conducting a standardized test for fitness. Waist circumference ( p=0.020), sagittal diameter ( p=0.035), body weight ( p=0.038) and BMI ( p=0.043) decreased significantly more in the intensive care group than in care as usual and the basic care group. However, the significance was abolished when differences in energy intake were accounted for. Conclusions: In an intention to treat, prospective lifestyle interventions with physical activity are feasible, but a high prevalence of comorbidities needs to be considered. Also, an intervention focused on isolated physical activity inevitably led to changes in diet with weight loss and significant improvement of essential risk factors in spite of the participants’ burden of chronic diseases.
