Inatividade física em idosos não institucionalizados: estudo de base populacionalPhysical inactivity among non-institutionalized elderly individuals: a population-based study

This study investigated the accuracy and precision of the Accutrend Plus system to determine blood glucose, total cholesterol, and plasma triglycerides in adults and evaluated its efficiency in measuring these blood variables. The sample consisted of 53 subjects (≥ 18 years). For blood variable laboratory determination, venous blood samples were collected and processed in a Labmax 240 analyzer. To measure blood variables with the Accutrend Plus system, samples of capillary blood were collected. In the analysis, the following tests were included: Wilcoxon and Student's t-tests for paired samples, Lin's concordance coefficient, Bland-Altman method, receiver operating characteristic curve, McNemar test, and k statistics. The results show that the Accutrend Plus system provided significantly higher values (p ≤ .05) of glucose and triglycerides but not of total cholesterol (p > .05) as compared to the values determined in the laboratory. However, the system showed good reproducibility (Lin's coefficient: glucose = .958, triglycerides = .992, total cholesterol = .940) and high concordance with the laboratory method (Lin's coefficient: glucose = .952, triglycerides = .990, total cholesterol = .944) and high sensitivity (glucose = 80.0%, triglycerides = 90.5%, total cholesterol = 84.4%) and specificity (glucose = 100.0%, triglycerides = 96.9%, total cholesterol = 95.2%) in the discrimination of high values of the three blood variables analyzed. It could be concluded that despite the tendency to overestimate glucose and triglyceride levels, a portable multi-analyzer is a valid alternative for the monitoring of metabolic disorders and cardiovascular risk factors.

The study objectives were to investigate the indicators of obesity most associated with high blood pressure in community-dwelling elderly and identify among these which one best discriminates high blood pressure. This is an epidemiological, population, cross-sectional and home-based study of elderly people (≥ 60 years, n = 316) residing in northeastern Brazil. The results showed that the body mass index and the body adiposity index were the indicators more closely associated with high blood pressure in both sexes. Both in female and male genders, body mass index showed high values of specificity and low sensitivity values for discriminating high blood pressure, whereas the body adiposity index showed high sensitivity and moderate specificity values. In clinical practice and health surveillance, it is suggested that both indicators be used as screening tools for hypertension in the elderly.

-The aim of this study was to analyze the association between diseases and chronic health conditions, multimorbidity and body mass index (BMI) in older adults from southern Brazil. Epidemiological cross-sectional study, with household basis was carried out with 343 older adults aged 60-79 years, selected by probability sampling and all aged 80 years or older (n=134). Hypertension, diabetes, cancer, chronic pulmonary diseases, coronary heart disease, cerebrovascular disease, arthritis, osteoporosis, depression, history of falls and dependency in activities of the daily living were assessed by self-report. Associations between independent variables and BMI (outcome) were tested using simple and multiple linear regression. Participated in the study 270 women (73.2±8.8 years) and 207 men (73.3±9.0 years). After adjustment (age, education, living arrangement, smoking, alcohol consumption, waist circumference, cognitive status and all other disease and chronic health conditions), the associations identified were: hypertension with higher BMI values (β 3.43; 95%CI: 2.38 to 4.48), for women, and chronic pulmonary disease with lower BMI values (β -2.05; 95%CI: -3.50 to -0.60). There was a linear trend between number of diseases and BMI for both sexes. Conclusion: The results showed an independent association between specific chronic diseases and BMI. Monitoring of nutritional status in older adults is important to identify extreme BMI values, especially those with more than two diseases and chronic health conditions.

Introdução: A funcionalidade tornou-se um fator determinante no processo de envelhecimento, tendo em vista que a manutenção da realização das atividades está associada a um envelhecimento saudável. Objetivo: Analisar a prevalência e fatores associados à incapacidade funcional em idosos residentes em comunidade. Metodologia: Trata-se de um estudo epidemiológico, transversal, de base populacional, aninhado uma coorte de idosos. Os dados foram obtidos através de compilação de instrumentos validados contendo informações sociodemográficas, doenças autorreferidas, sintomatologia depressiva, nível de atividade física, hábitos de vida, índice de massa corporal, e dependência/independência. Para análise das variáveis utilizou-se o teste qui-quadrado (x2) e para as variáveis que obtiveram p
