Lower muscular strength is associated with greater liver fat content and higher serum liver enzymes-"The Sedentary's Liver" The Study of Health in Pomerania.

We investigated the associations of low handgrip strength (HGS, i.e., a marker of muscular fitness) with liver fat content (LFC) and serum liver enzymes in a population-based setting. We used data from 2700 participants (51.7% women), aged 21-90 years, from two independent cohorts of the population-based Study of Health in Pomerania (SHIP-START-2 and SHIP-TREND-0). Cross-sectional, multivariable adjusted regression models were performed to examine the associations of HGS with LFC, measured by magnetic resonance imaging and serum liver enzymes. We found significant inverse associations of HGS with both LFC and serum liver enzymes. Specifically, a 10-kg lower HGS was associated with a 0.59% (95% confidence interval [CI]: 0.24-0.94; p = 0.001) higher LFC, a 0.051 µkatal/L (95% CI: 0.005-0.097; p = 0.031) higher gamma-glutamyltransferase (GGT) concentration and a 0.010 µkatal/L (95% CI: 0.001-0.020; p = 0.023) higher aspartate aminotransferase (AST) concentration. The adjusted odds-ratio for prevalent hepatic steatosis (defined by a MRI-PDFF ≥5.1%) per 10-kg lower HGS was 1.21 (95% CI: 1.04-1.40; p = 0.014). When considering only obese individuals, those with low HGS had a 1.58% (95% CI: 0.18-2.98; p = 0.027) higher mean LFC and higher chance of prevalent hepatic steatosis (adjusted OR 1.74, 95% CI: 1.15-2.62; p = 0.009) compared to individuals with high HGS. We found similar associations in individuals with overweight, but not in those with normal weight. Lower HGS was strongly associated with both higher LFC and higher serum GGT and AST concentrations. Future studies might clarify whether these findings reflect adverse effects of a sedentary lifestyle or aging on the liver.

Cardiac remodelling in non-alcoholic fatty liver disease in the general population.

BACKGROUND AND AIMS: Non-alcoholic fatty liver disease (NAFLD) is associated with increased risk for cardiovascular disease. Our study investigates the contribution of NAFLD to changes in cardiac structure and function in a general population. METHODS: One thousand ninety-six adults (49.3% female) from the Study of Health in Pomerania underwent magnetic resonance imaging including cardiac and liver imaging. The presence of NAFLD by proton density fat fraction was related to left cardiac structure and function. Results were adjusted for clinical confounders using multivariable linear regression model. RESULTS: The prevalence for NAFLD was 35.9%. In adjusted multivariable linear regression models, NAFLD was positively associated with higher left ventricular mass index (ß = 0.95; 95% confidence interval (CI): 0.45; 1.45), left ventricular concentricity (ß = 0.043; 95% CI: 0.031; 0.056), left ventricular end-diastolic wall thickness (ß = 0.29; 95% CI: 0.20; 0.38), left atrial end-diastolic volume index (ß = 0.67; 95% CI: 0.01; 1.32) and inversely associated with left ventricular end-diastolic volume index (ß = -0.78; 95% CI: -1.51; -0.05). When stratified by sex, we only found significant positive associations of NAFLD with left ventricular mass index, left atrial end-diastolic volume index, left ventricular cardiac output and an inverse association with global longitudinal strain in women. In contrast, men had an inverse association with left ventricular end-diastolic volume index and left ventricular stroke volume. Higher liver fat content was stronger associated with higher left ventricular mass index, left ventricular concentricity and left ventricular end-diastolic wall thickness. CONCLUSION: NAFLD is associated with cardiac remodelling in the general population showing sex specific patterns in cardiac structure and function.

Associations of spleen volume with markers of blood count and lipid profile in a large population-based study.

Background: The aim of our study was to investigate associations of spleen volume with blood count markers and lipid profile in the general population. Materials & methods: Cross-sectional data from 1,106 individuals aged 30-90 years from the population-based Study of Health in Pomerania (SHIP-START-2) were analyzed. Blood count markers included red blood cell (RBC) counts, hemoglobin, platelet count, and white blood cell (WBC) counts. Lipid profile included total-cholesterol, high-density lipoprotein-cholesterol (HDL-C), and low-density lipoprotein-cholesterol (LDL-C) as well as triglycerides. Linear regression models adjusted for age, sex, body height, and weight were used to associate standardized spleen volume with blood counts and lipid profile markers. Results: Spleen volume was positively associated with RBC (ß = 0.05; 95% confidence interval [CI] = 0.03 to 0.08) and hemoglobin (ß = 0.05; 95% CI = 0.01 to 0.09) but inversely with platelet count (ß = -16.3; 95% CI = -20.5 to -12.1) and WBC (ß = -0.25; 95% CI = -0.37 to -0.14). Furthermore, spleen volume showed inverse associations with total cholesterol (ß = -0.17; 95% CI = -0.24 to -0.09), HDL-C (ß = -0.08; 95% CI = -0.10 to -0.05), and LDL-C (ß = -0.12; 95% CI = -0.17 to -0.06). There was no significant association of spleen volume with triglycerides. Conclusion: Our study showed that the spleen volume is associated with markers of the blood count and lipid profile in the general population.

Correlation of systolic and diastolic blood pressure with echocardiographic phenotypes of cardiac structure and function from three German population-based studies.

Arterial hypertension is considered a risk factor for the development of heart failure. Here we investigate cross-sectional associations of systolic and diastolic blood pressure with subtle functional and morphological changes of left ventricular echocardiographic parameters representing early dysfunction in three representative German population-based studies. We assessed 26,719 individuals without symptomatic heart failure from the Hamburg City Health Study (HCHS, n = 7396, derivation cohort), the Gutenberg Health Study (GHS, 14,715, validation cohort) and the Study of Health in Pomerania (SHIP, 4608, validation cohort). Multivariable linear regression analyses with systolic and diastolic blood pressure as continuous exposure variables were adjusted for common cardiovascular risk factors and antihypertensive medication. Both systolic and diastolic blood pressure were consistently associated with measures of left ventricular hypertrophy (ß per standard deviation (SD) for LV mass (g) and systolic blood pressure: 5.09 (p < 0.001); diastolic blood pressure: 2.29 (p < 0.001) in HCHS). Systolic blood pressure correlated with declining diastolic function (ß per SD for E/e': 0.29, p < 0.001 in HCHS) and diastolic blood pressure with declining systolic function (ß per SD for LVEF, in %: - 0.15; p = 0.041 in HCHS) in all cohorts. Pending further validation, our results from three independent German population samples suggest differential effects of systolic versus diastolic blood pressure on left ventricular structure and function.

Association of moderate and vigorous physical activity and relative muscle strength with neck circumference: a cross-sectional analysis of the Study of Health in Pomerode (SHIP-Brazil).

OBJECTIVE: Neck circumference is a simple anthropometric measurement that may be linked to chronic diseases, physical activity, and muscle strength. We sought to verify the association of moderate and vigorous physical activity levels and relative muscle strength with neck circumference in a community in southern Brazil. METHODS: We cross-sectionally analyzed data from 2,488 participants (51% women), aged 20-79 years old from the Study of Health in Pomerode (SHIP-Brazil) conducted in Pomerode, Santa Catarina, Brazil. Increased neck circumference was defined with cutoff points of >39cm for men and >35cm for women. The independent variables were the level of moderate and vigorous physical activity using the short International Physical Activity Questionnaire, and relative muscle strength using the handgrip test and body mass. Univariate and multiple Poisson regression models were used to determine the association between variables (p≤0.05). RESULTS: The prevalence of increased neck circumference was 48.2% (60.4% in men, 39.6% in women) and was associated with low relative muscle strength (PR=1.26, 95%CI: 1.17-1.35) in men, insufficient moderate and vigorous physical activity levels (PR=1.23, 95%CI: 1.14-1.32), and relative muscle strength (PR=1.73, 95%CI: 1.61-1.87) in women. After adjusting for covariates, no significant associations were observed between insufficient moderate and vigorous physical activity levels in men (PR=1.02, 95%CI: 0.95-1.07). CONCLUSION: Increased neck circumference seems to be an important predictor of low moderate and vigorous physical activity and relative strength loss in adults, and more pronounced in women.

Sphingosine-1-phosphate levels are inversely associated with left ventricular and atrial chamber volume and cardiac mass in men : The Study of Health in Pomerania (SHIP).

AIMS: Sphingosine-1-phosphate (S1P) is a signaling lipid, which is involved in several cellular processes including cell growth, proliferation, migration and apoptosis. The associations of serum S1P levels with cardiac geometry and function are still not clear. We investigated the associations of S1P with cardiac structure and systolic function in a population-based sample. METHODS AND RESULTS: We performed cross-sectional analyses of 858 subjects (467 men; 54.4%), aged 22 to 81 years, from a sub-sample of the population-based Study of Health in Pomerania (SHIP-TREND-0). We analyzed the associations of serum S1P with structural and systolic function left ventricular (LV) and left atrial (LA) parameters as determined by magnetic resonance imaging (MRI) using sex-stratified multivariable-adjusted linear regression models. In men, MRI data showed that a 1 µmol/L lower S1P concentration was associated with an 18.1 mL (95% confidence interval [CI] 3.66-32.6; p = 0.014) larger LV end-diastolic volume (LVEDV), a 0.46 mm (95% CI 0.04-0.89; p = 0.034) greater LV wall thickness (LVWT) and a 16.3 g (95% CI 6.55-26.1; p = 0.001) higher LV mass (LVM). S1P was also associated with a 13.3 mL/beat (95% CI 4.49-22.1; p = 0.003) greater LV stroke volume (LVSV), an 18.7 cJ (95% CI 6.43-30.9; p = 0.003) greater LV stroke work (LVSW) and a 12.6 mL (95% CI 1.03-24.3; p = 0.033) larger LA end-diastolic volume (LAEDV). We did not find any significant associations in women. CONCLUSIONS: In this population-based sample, lower levels of S1P were associated with higher LV wall thickness and mass, larger LV and LA chamber sizes and greater stroke volume and work of the LV in men, but not in women. Our results indicate that lower levels of S1P were associated with parameters related with cardiac geometry and systolic function in men, but not in women.

[Meat consumption by adults and the elderly in a city colonized by Germans in the south of Brazil: a population-based study]. / Consumo de carnes por adultos e idosos de uma cidade de colonização alemã do sul do Brasil: estudo de base populacional.

Excessive meat consumption, especially red and processed meats, is associated with increased morbidity and mortality. The pattern of meat consumption varies in Brazil and is influenced by economic and cultural factors in the world. The study aimed to analyze the consumption of meat by adults and the elderly in a city colonized by Germans in the south of Brazil. It involved a cross-sectional population study. Sociodemographic and meat consumption data were collected using a previously validated Food Frequency Questionnaire. Frequencies and amounts were analyzed by type of meat and processing. The association between excessive meat consumption and the study variables was estimated by Prevalence Ratio. Among the 1,941 participants, the average amount of meat consumed was 250 g/day, the most consumed being white unprocessed meat (138 g/day), especially poultry (80 g/day). The prevalence of excessive consumption of red and processed meat (more than 500 g/week) was 63%, mainly among men (PR=1.6; 95%CI 1.5-1.8), aged 20 to 29 years (PR=1.4; 95%CI 1.2-1.5), and higher economic class (PR=1.2; 95%CI 1.0-1.3). Excessive consumption of red and processed meat among young men of upper economic class should be the target of public health actions for the adequacy of food consumption.

O consumo excessivo de carnes, em especial as vermelhas e processadas, está associado ao aumento da morbi-mortalidade. O padrão de consumo de carnes varia no Brasil e no mundo influenciado por fatores econômicos e culturais. O estudo buscou analisar o consumo de carnes por adultos e idosos de uma cidade de colonização alemã do sul do Brasil. Trata-se de estudo populacional seccional. Foram coletados dados sociodemográficas e de consumo de carne por Questionário de Frequência Alimentar previamente validado. Foram analisadas as frequências, e as quantidades por tipo de carne e processamento. A associação entre o consumo excessivo de carne e as variáveis de estudo foi estimada por Razão de Prevalência. Entre os 1.941 participantes, a média de carne consumida foi de 250 g/dia, sendo a carne não processada branca (138 g/dia) a mais consumida, com destaque para as aves (80 g/dia). A prevalência de consumo excessivo de carne vermelha e processada (mais que 500 g/semana) foi de 63%, principalmente entre os homens (RP=1,6; IC95% 1,5-1,8), de 20 a 29 anos (RP=1,4; IC95% 1,2-1,5), e mais alta classe econômica (RP=1,2; IC95% 1,0-1,3). O consumo excessivo de carne vermelha e processada entre homens jovens de classe econômica alta deve ser alvo de ações de saúde pública para a adequação no consumo alimentar.

Maternal socioeconomic and lifestyle factors and life dissatisfaction associated with a small for gestational age infant. The Survey of Neonates in Pomerania (SNiP).

PURPOSE: The aim is to investigate the associations of the mother's socioeconomic and lifestyle factors and life satisfaction with the delivery of a small for gestational age (SGA) infant. METHODS: Data from 4598 participants of the population-based birth cohort study Survey of Neonates in Pomerania (SniP) including comprehensive information on pregnancies, mothers, and their offspring in Western Pomerania, Germany were used in this study. The associations were analyzed using linear and logistic regression models. RESULTS: After logistic regression analysis adjusted for height of the mother, women who delivered SGA infants, had lower education (p < 0.01) and smoked more frequently during pregnancy (p < 0.01) compared with mothers of adequate for gestational age (AGA) neonates. A mother with less than 10 years of education and one who continued smoking during pregnancy had an odds ratio (OR) of 2.23 [95% confidence interval (CI) = 1.44 to 3.46] and 2.68 (95% CI = 2.06-3.49) of having an SGA infant, respectively. There was no association between the employment of the mother (p = 0.28), the monthly income (p = 0.09), the family status (p = 0.80), the number of friendships outside the household that the mother would not wish to relinquish (p = 0.47), the number of people that she could rely on in case of an emergency (p = 0.75), or alcohol consumption prior to (p = 0.14) or during the pregnancy (p = 0.99) with SGA. Finally, women who delivered SGA infants were more frequently dissatisfied with their employment (p = 0.03) and financial status (p < 0.01). CONCLUSIONS: Women who delivered SGA infants had more associated socioeconomic and lifestyle risk factors and were more frequently dissatisfied with their life conditions than mothers of AGA neonates.

After adjusting for covariates, no significant associations were observed between insufficient moderate and vigorous physical activity levels in men (PR=1.02, 95%CI: 0.95-1.07). Conclusion Increased neck circumference seems to be an important predictor of low moderate and vigorous physical activity and relative strength loss in adults, and more pronounced in women.

Effects of Apolipoprotein E polymorphism on carotid intima-media thickness, incident myocardial infarction and incident stroke.

The Apolipoprotein E (APOE) gene polymorphism (rs429358 and rs7412) shows a well-established association with lipid profiles, but its effect on cardiovascular disease is still conflicting. Therefore, we examined the association of different APOE alleles with common carotid artery intima-media thickness (CCA-IMT), carotid plaques, incident myocardial infarction (MI) and stroke. We analyzed data from 3327 participants aged 20-79 years of the population-based Study of Health in Pomerania (SHIP) from Northeast Germany with a median follow-up time of 14.5 years. Linear, logistic, and Cox-regression models were used to assess the associations of the APOE polymorphism with CCA-IMT, carotid plaques, incident MI and stroke, respectively. In our study, the APOE E2 allele was associated with lower CCA-IMT at baseline compared to E3 homozygotes (ß: - 0.02 [95% CI - 0.04, - 0.004]). Over the follow-up, 244 MI events and 218 stroke events were observed. APOE E2 and E4 allele were not associated with incident MI (E2 HR: 1.06 [95% CI 0.68, 1.66]; E4 HR: 1.03 [95% CI 0.73, 1.45]) and incident stroke (E2 HR: 0.79 [95% CI 0.48, 1.30]; E4 HR: 0.96 [95% CI 0.66, 1.38]) in any of the models adjusting for potential confounders. However, the positive association between CCA-IMT and incident MI was more pronounced in E2 carriers than E3 homozygotes. Thus, our study suggests that while APOE E2 allele may predispose individuals to lower CCA-IMT, E2 carriers may be more prone to MI than E3 homozygotes as the CCA-IMT increases. APOE E4 allele had no effect on CCA-IMT, plaques, MI or stroke.

Association of Cardiopulmonary Exercise Capacity and Adipokines in the General Population.

Adipokines and cardiorespiratory fitness (CRF) are associated with the (patho)physiology of cardiometabolic diseases. Whether CRF and adipokines are related is unclear. We investigated associations of CRF with leptin, adiponectin, chemerin, resistin and vaspin. Data from the population-based Study of Health in Pomerania was used (n=1,479; median age 49 years; 51% women). Cardiopulmonary exercise testing was used to measure CRF. Circulating adipokine concentrations were measured by enzyme-linked immunosorbent assay. The association between CRF and adipokines was assessed using multivariable sex-specific quantile regression models. Higher maximum oxygen uptake was significantly associated with lower leptin (men:-0.11 ng/ml; 95%-confidence interval [CI]:-0.18 to-0.03 ng/ml; p<0.005; women:-0.17 ng/ml; 95%-CI:-0.33 to-0.02 ng/ml; p<0.05) and chemerin (men:-0.26 ng/ml; 95%-CI:-0.52 to-0.01 ng/ml; p<0.05; women:-0.41 ng/ml; 95%-CI:-0.82 to-0.01 ng/ml; p<0.05) as well as higher adiponectin concentrations (men: 0.06 µg/ml; 95%-CI: 0.02 to 0.11 µg/ml; p<0.05; women: 0.03 µg/ml; 95%-CI:-0.05 to 0.10 µg/ml; p=0.48). We found that CRF was inversely associated with leptin and chemerin in both sexes and positively associated with adiponectin only in men.

Longitudinal association of Apolipoprotein E polymorphism with lipid profile, type 2 diabetes and metabolic syndrome: Results from a 15 year follow-up study.

AIMS: To examine the association of different APOE alleles with type 2 diabetes mellitus (T2DM) and metabolic syndrome (MetS) as well as the influence of high-sensitive C-reactive protein (hs-CRP) on these associations. METHODS: We analyzed data from 3917 participants aged 20-81 years of the population-based Study of Health in Pomerania (SHIP) from Northeast Germany with a median follow-up time of 10.8 years. Linear and logistic mixed models were performed to test the association of APOE alleles with T2DM and MetS. RESULTS: We observed 393 T2DM and 1411 MetS events at baseline, and 576 T2DM and 1342 MetS events over the follow-up. The E4 carriers had a lower odds of developing T2DM (OR: 0.47 [0.24, 0.94]) than E3 homozygotes even after adjustment for potential confounders. The E2 carriers showed no associations. The inverse association between E4 alleles and T2DM moderately attenuated after adjustment for hs-CRP levels. The lower odds of developing T2DM in E4 carriers was more pronounced in participants without obesity, hypertension or MetS. However, both E2 and E4 carriers had higher odds of developing MetS (E2 OR: 1.45 [1.03, 2.03]; E4 OR: 1.56 [1.17, 2.09]) than E3 homozygotes. CONCLUSIONS: While the presence of APOE E4 allele might increase the chance of MetS through its major action on lipids, E4 allele might offer a protection towards T2DM through its influence on inflammation.

Low cardiopulmonary fitness is associated with higher liver fat content and higher gamma-glutamyltransferase concentrations in the general population - "The Sedentary's Liver".

BACKGROUND: We investigated the association between low cardiorespiratory fitness and liver fat content (LFC) in the general population. MATERIALS AND METHODS: We evaluated data from 2151 adults (51.1% women) from two population-based cohorts of the Study of Health in Pomerania (SHIP-2 and SHIP-TREND-0). We analysed the cross-sectional associations of peak oxygen uptake (VO2peak ) with LFC, assessed by magnetic resonance imaging proton density fat fraction, as well as serum gamma-glutamyltransferase (GGT) and aminotransferase concentrations by multivariable regression models. RESULTS: We observed significant inverse associations of VO2peak with LFC and serum GGT, but not with serum aminotransferase levels. Specifically, a 1 L/min lower VO2peak was associated with a 1.09% (95% confidence interval [CI]: 0.45-1.73; P = .002) higher LFC and a 0.18 µkatal/L (95% CI: 0.09-0.26; P < .001) higher GGT levels. The adjusted odds ratio (OR) for the risk of prevalent hepatic steatosis (HS) by a 1 L/min decrease in VO2peak was 1.61 (95% CI: 1.22-2.13; P = .001). Compared to subjects with high VO2peak , obese and overweight individuals with low VO2peak had 1.78% (95% CI: 0.32-3.25; P = .017) and 0.94% (95% CI: 0.15-1.74; P = .021) higher mean LFC, respectively. Compared to those with high VO2peak , low VO2peak was independently associated with a higher risk of prevalent HS in the obese (adjusted-OR 2.29, 95% CI=1.48-3.56; P < .001) and overweight (adjusted OR 1.57, 95% CI=1.16-2.14; P = .04) groups. CONCLUSIONS: Lower VO2peak was significantly associated with greater LFC and higher serum GGT levels in a population-based cohort of adult individuals. Our results suggest that low VO2peak might be a risk factor for HS.

The site of waist measurement impacts the estimation of visceral fat: results from three-dimensional photonic body scanning.

Currently, various protocols regarding the site of waist circumference (WC) measurement are in place. This study aimed to analyse the effect of the site of WC measurement on visceral adipose tissue (VAT) estimation. WC was obtained at 7 anatomical sites in 211 German volunteers (103 males) aged 23-81 years using three-dimensional photonic body scanning (PBS). At one site, WC was additionally measured by tape. The quantity of VAT was assessed by MRI. Models to estimate VAT based on WC were developed; the precision of the estimation is represented by R2. The influence of the applied method of WC assessment (tape v. PBS) on the estimations is reported. Results show that the amount of estimated VAT and the precision of VAT estimation were dependent on the site of measurement. VAT was estimated most precisely by WC taken at the level of the lowest rib (WCrib: R2 = 0·75 females; 0·79 males), the minimum circumference (WCmin: R2 = 0·75 females; 0·77 males) and at the narrowest part of the torso (WCnar: R2 = 0·76 females; 0·77 males), and least precisely by WC assessed at the top of iliac crest (WCiliac: R2 = 0·61 females; 0·60 males). VAT estimates based on WC obtained by PBS were smaller and estimations were slightly less precise compared to estimates based on tape measures. Our results indicate that the method and the site of waist measurement should be considered when estimating VAT based on WC. The implementation of a standardised protocol using either WCrib, WCmin or WCnar could improve the precision of VAT estimation.

Intestinal parasitoses and associated factors in a Brazilian city of German's descendants: a population-based study.

Intestinal parasitoses are a recurrent public health problem in developing countries. Their occurrence is usually associated with poor socioeconomic status and environmental risk factors. This study aims to estimate the prevalence of intestinal parasites and associated risk factors in Pomerode, SC. This was a cross-sectional sample with participants from population-based cohort study SHIP-Brazil (n=2,488). Sociodemographic, lifestyle, and environmental variables were selected from the study database. The stool samples were analyzed by Hoffman, Pons, and Janer, and by Faust methods. We estimated the relative frequency of parasites and its association to the study variable was estimated by prevalence ratio (PR) in a Poisson regression model. Among those who provided stool sample (n=797), the prevalence was 10.8% (95% CI 8.6 to 13.4). Endolimax nana, 4.8% (95% CI, 3.5-6.7) was the most frequent parasite, followed by Entamoeba histolytica/dispar, 1.7% (95% CI, 0.8-3.3), Urbanorum spp., 1.6% (95% CI, 1.0-2.7). Men (PR=1.9 95% CI 1.2-2.9), olders (PR=1.7 95% CI 1.0-2.8), non-white (PR=1.9 95% CI 1.2-3.0), living in high-risk dwelling areas (PR=1.8 95% CI 1.4-2.4) were associated with elevated proportions of parasitosis in the adjusted model. The current study found a low frequency of intestinal parasitoses in Pomerode, SC, Brazil. This frequency was higher among males, older, who live alone, non-white, in low SES, and living in high-risk dwelling areas.

Insufficient physical activity and multimorbidity was associated with low physical functional performance in older adults: a cross-sectional study / Atividade física insuficiente e multimorbidade foram associadas ao baixo desempenho físico funcional em idosos: um estudo transversal

Aging, physical inactivity, and chronic disease can decrease strength and muscle mass and affect mobility and autonomy in older adults. This study aimed to analyze the prevalence and associated factors of low physical functional performance among older adults in the city of Pomerode, in southern Brazil. Methods: This is a cross-sectional population-based study with data on 733 older adults from the Study of Health in Pomerode ­ SHIP-Brazil. Low functional physical performance was defined as handgrip strength ≤ 32 kg for men or ≤ 20 kg for women and/or a Timed Up and Go test ≥ 11 seconds for men or ≥ 13 seconds for women. Associations were analyzed by multiple logistic regression. Results: The prevalence of low physical functional performance was 43.7% (42.2% among women and 45.5% among men). Low physical functional performance was associated with the 70­79 years age group (odds ratio [OR] = 2.07) and insufficient physical activity (OR = 2.73) in men, and with the 70­79 years age group (OR = 2.09) and multimorbidity (OR = 1.87) in women. In general, older age, insufficient physical activity, and multimorbidity were associated with low physical functional performance in older adults.

O envelhecimento, o sedentarismo e as doenças crônicas podem diminuir a força e a massa muscular e afetar a mobilidade e a autonomia do idoso. O objetivo deste estudo foi analisar a prevalência e os fatores associados ao baixo desempenho funcional em idosos de uma cidade de origem pomerana no sul do Brasil. Metodologia: Estudo transversal de base populacional com dados de 733 idosos do Estudo Vida e Saúde em Pomerode ­ ShipBrazil. O baixo desempenho físico funcional foi definido como a força de preensão palmar ≤ 32 kg para os homens ou ≤ 20 kg para as mulheres e(ou) timed up and go ≥ 11 segundos para os homens ou ≥ 13 segundos para as mulheres. As associações foram analisadas por regressão logística múltipla. Resultados: A prevalência de baixo desempenho físico funcional foi de 43,7% (42,2% idosas e 45,5% idosos). O baixo desempenho físico funcional foi associado à idade, 70-79 anos (OR = 2,07), e à atividade física insuficiente (OR = 2,73) nos homens; e à idade, 70­79 anos (OR = 2,09), e à presença de multimorbidade (OR = 1,87) nas mulheres. Em geral, maior idade, atividade física insuficiente e multimorbidade foram associadas ao baixo desempenho físico funcional entre os idosos.

Educational Level, but Not Income or Area Deprivation, is Related to Macrovascular Disease: Results From Two Population-Based Cohorts in Germany.

Objectives: An inverse relationship between education and cardiovascular risk has been described, however, the combined association of education, income, and neighborhood socioeconomic status with macrovascular disease is less clear. The aim of this study was to evaluate the association of educational level, equivalent household income and area deprivation with macrovascular disease in Germany. Methods: Cross-sectional data from two representative German population-based studies, SHIP-TREND (n = 3,731) and KORA-F4 (n = 2,870), were analyzed. Multivariable logistic regression models were applied to estimate odds ratios and 95% confidence intervals for the association between socioeconomic determinants and macrovascular disease (defined as self-reported myocardial infarction or stroke). Results: The study showed a higher odds of prevalent macrovascular disease in men with low and middle educational level compared to men with high education. Area deprivation and equivalent income were not related to myocardial infarction or stroke in any of the models. Conclusion: Educational level, but not income or area deprivation, is significantly related to the macrovascular disease in men. Effective prevention of macrovascular disease should therefore start with investing in individual education.
