RESUMO

The scarcity of Brazilian data on the effects of loss of muscle strength and function and self-rated heath in old age, as well as the evidence according with self-rated health is an important antecedent of self-care and well-being are good reasons to investigate relationships between these variables. Objective: Investigating patterns of performance and relationships between grip strength, gait speed and self-rated health in community-dwelling elderly stratified by gender, age and family income. Methods: 689 elderly people without cognitive deficit suggestive of dementia were submitted to 3 measures of grip strength with dynamometer Jamar and to 3 measures of time spent to walk 4,6 m. The means were respectively adjusted by gender and BMI and by gender and height. Comparisons between groups were based on their quartiles of strength and speed. Self-related health was assessed with a five point scale. Results: The male and the youngest scored significantly higher on grip strength and gait speed than the female and oldest did; the richest scored higher than the poorest on grip strength and gait speed; those aged greater than 80 and female showed lower grip strength and gait speed than the youngest and male did. The poorest scored lower and the richest higher than the other groups in self-rated health. Multivariate regression analysis showed low gait speed and low income as risk factors to worse health evaluation. Conclusion: The association between low muscular strength and worse self-evaluations of health is mediated by functional incapacities in interaction with insufficient environmental resources
