RESUMO

There is consensus on the importance of physical activity for health promotion for older people, but there is controversy about the methods to evaluate it, just as there are difficulties to discriminate between the effects of health variables and and behavioral variables on your practice. Objective: Examining relationships between frailty indicated by weight loss, fatigue, low grip strength, slow gait and comorbidities, and physical activity levels assessed by two different criteria, recruited in the elderly in the community, grouped by gender, age and income level familiar. Methods: 689 subjects selected for performance above the cutoff score on the Mini-Mental State Examination, a sample of 900 elderly people recruited from home in urban census tracts of Campinas drawn at random. The average age was 72.28 + 5.40 and the average monthly income of 4.72 minimum wages + 5.27; 68.21% were women. The physical activity levels were measured by the adapted version of the "Minnesota Leisure Time Physical Activity Questionnaire". Unintentional weight loss over the past 12 months, depletion and chronic diseases diagnosed by a physician, were assessed by self-reported. Handgrip strength in kgs/force corresponded to the average of three attempts with Jamar dynamometer in the dominant hand. Gait speed was indicated by the average time spent to travel 4.6 meters (three attempts). The level of physical activity was indicated by two criteria: regular weekly practice and accumulated 150 minutes of moderate exercise or 120 minutes of vigorous physical exercise and weekly rate of caloric expenditure above the first quintile of the distribution of values obtained by exercise physical and domestic activities, adjusted for weight and sex. Scored for fragile elderly people who have lost at least 4.5 kg or 5% of body weight; respondents always or almost always either of two scale items on fatigue, which scored below the first quintile of the test and hold above the percentile 80 in the test running, and who reported having at least three chronic diseases. Results: The prevalence of elderly people who lost weight was 15,09% of those with fatigue, 17.13%, low grip strength, 16.96%, slow gait, 15.87%, and three or more chronic diseases, 43.02%. The frequency of assets by the criterion of calorie expenditure was 83.55% by the criterion of regular physical exercise, 45.27%. There were positive associations between low caloric and low grip strength, slow gait and age, as between a sedentary lifestyle with exercise and physical comorbidities. Conclusions: The different relationships observed between the two types of measurement of physical activity and indicators of frailty can be attributed to methodological issues, the health conditions and the influence of attitudes, values and motivations on the accession of elderly men and women to practice physical exercise and performance of household chores. Public policies to encourage regular exercise and physical productive activities at home for the elderly, should take into account cultural and behavioral issues, especially when the target is people with lower income and poorer health
