          Abstract

          O objetivo foi investigar as relações entre força muscular nos membros inferiores e nos superiores, prática de exercícios físicos e atividades de vida diária em mulheres idosas recrutadas na comunidade. Um mil quinhentas e trinta e oito idosas com idade média = 72,07 ± 5,46, renda familiar média = 3,59 ± 3,96 SM, sem déficit cognitivo sugestivo de demência. Foram submetidas a medidas de força de preensão manual e velocidade de marcha; a itens de autorrelato sobre prática regular de exercícios físicos; de desempenho de 13 atividades avançadas de vida diária (AAVD) de natureza social (ex: trabalhar, viajar e frequentar igreja) e de 3 atividades instrumentais de vida diária (AIVD) manejar dinheiro, fazer compras e usar transporte, 1.538 idosas com idade média = 72,07 ± 5,46, renda familiar média = 3,59 ± 3,96 SM, sem déficit cognitivo sugestivo de demência. Foram preditivos de pior desempenho em atividades de vida diária (AVD): baixa força muscular (OR = 2,48 para comprometimento da preensão e da marcha e 1,66 para comprometimento em qualquer dos critérios), baixa renda (OR = 2,46 e 2,45 para < 1 e para 1,1 a 3,0 SM) e sedentarismo (OR 2,08). A funcionalidade de mulheres idosas é afetada pelo envelhecimento fisiológico e por condições contextuais e de estilo de vida.

          The scope of this study was to investigate relationships between muscle strength of the upper and lower limbs, physical exercise, and functionality to perform complex activities of day-to-day life in elderly women recruited from the community. 1538 elderly women with mean age = 72.07 ± 5.46 and average household income = 3.59 ±3.96 MW, without cognitive deficit suggestive of dementia, were submitted to tests of grip strength and walking speed. They were asked to self-report on regular practice of physical exercise and performance of 13 social AADLs (e.g. working, travelling and church attendance) and 3 IADLs (handling money, doing the shopping and using public transport). The worst performance key factors were low grip strength and low gait speed in ADL (OR = 2.48 if both; OR = 1.66 if either were present), as well as low income (OR = 2.46 low income < 1 MW and = 2.45 to 1.1 and 3.0 MW) and sedentary life style (OR = 2.08). The functionality of elderly women is influenced by physiological aging, but also by contextual conditions and life style.

            Job strain, blood pressure and response to uncontrollable stress.

            The association between cardiovascular disease risk and job strain (high-demand, low-control work) may be mediated by heightened physiological stress responsivity. We hypothesized that high levels of job strain lead to increased cardiovascular responses to uncontrollable but not controllable stressors. Associations between job strain and blood pressure reductions after the working day (unwinding) were also assessed. Assessment of cardiovascular responses to standardized behavioral tasks, and ambulatory monitoring of blood pressure and heart rate during a working day and evening. We studied 162 school teachers (60 men, 102 women) selected from a larger survey as experiencing high or low job strain. Blood pressure, heart rate and electrodermal responses to an externally paced (uncontrollable) task and a self-paced (controllable) task were assessed. Blood pressure was monitored using ambulatory apparatus from 0900 to 2230 h on a working day. The groups of subjects with high and low job strain did not differ in demographic factors, body mass or resting cardiovascular activity. Blood pressure reactions to the uncontrollable task were greater in high than low job-strain groups, but responses to the controllable task were not significantly different between groups. Systolic and diastolic blood pressure did not differ between groups over the working day, but decreased to a greater extent in the evening in subjects with low job strain. Job strain is associated with a heightened blood pressure response to uncontrollable but not controllable tasks. The failure of subjects with high job strain to show reduced blood pressure in the evening may be a manifestation of chronic allostatic load.
