1653/2011 - EXERCÍCIOS FÍSICOS, FORÇA MUSCULAR E ATIVIDADES DE VIDA DIÁRIA EM MULHERES IDOSAS PHYSICAL EXERCISE, MUSCLE STRENGTH AND ACTIVITIES OF FUNCTIONAL ABILITY IN COMMUNITY-DWELLING ELDERLY WOMEN
Objetivo: investigar as relações entre força muscular nos membros inferiores e superiores, pratica de exercícios físicos e atividades de vida diária em mulheres idosas recrutadas na comunidade. Métodos: 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 submetidas a medidas de força de preensão manual e velocidade de marcha e a itens de autorrelato sobre prática regular de exercícios físicos, desempenho de 13 AAVDs de natureza social (ex: trabalhar, viajar e frequentar igreja) e das AIVDs manejar dinheiro, fazer compras e usar transporte. Resultados: 60,4% eram sedentárias; 17,21% tinham baixa força de preensão e 16,43% lentidão da marcha; 54,32% pontuaram abaixo da mediana calculada para as AAVDs e AIVDs. Entre as de 80 anos e mais houve frequência significantemente mais alta de sedentarismo, baixa força de preensão, lentidão da marcha e menor número de AAVDs preservadas. Foram preditivos de pior desempenho em AVDs: 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). Conclusão: a funcionalidade de mulheres idosas é afetada pelo envelhecimento fisiológico e por condições contextuais e de estilo de vida.

Abstract:
Objective: To investigate relationships between muscle strength of upper and lower extremities, physical exercises, and functionality to perform complex activities of daily life in community-dwelling elderly women. Methods: 1538 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 measures of grip strength and walking speed and to self-report items on regular practice of physical exercise and performance of 13 social AADL (ex: working, travelling and church attendance) and 3 IADL (money, shopping and transportation). Results: According with the criteria of the American College of Sports Medicine, 60.4% were sedentary; 17.21% had low grip strength and 16.43%, low gait speed; 54.32% scored below the sample´s median of ADL performance. Among those aged 80 and above there were higher frequencies of sedentary life style and low grip strength, gait speed and functionality in ADL. Low grip strength and low gait speed predicted worse performance in ADL (OR = 2,48 if both; OR = 1,66 if either were present), as well as low income (OR = 2,46 to income < 1 MW and = 2,45 to 1,1 and 3,0 MW) and sedentary life style (OR = 2,08). Conclusion: Elderly women have their functionality influenced by physiological aging, but also by contextual conditions and life style.
