Profile of the body mass index and associated factors in active elderlies

This is an analytical type of research with cross-sectional design and quantitative approach, with sample represented by 105 elderly people. The research instrument consisted of Cognitive assessment, Sociodemographic data, Health conditions and Motor performance evaluation. The data were analyzed by using descriptive analysis and binary logistic regression.

Results:

The elderlies without partners have 7.753 times the chance of presenting excess weight when compared to those with partners. Having an income higher than a minimum wage represents 6.014 times the chance of being overweight. Not having health problems amounts to 0.015 times the chance of being overweight. In the motorperformance, not presenting limitation of balance represents 6.785 times the possibility of being affected by excess weight.
