Weight gain among elderly women as risk factor for disability: Health, Well-being and Aging Study (SABE Study)

Abstract

Objective: To examine the association between weight change and the incidence of disability in activities of daily living (ADL) among elderly women.

Method: In 2006, 227 women aged ≥75 years and independent in ADL were selected from SABE Study (Health, Well-being, and Aging) in Sao Paulo, Brazil. The dependent variable was the report of difficulty on ≥1 ADL in 2009. Differences in weight were calculated between baseline and second interview, and converted to percentage change in relation to initial weight. A change (gain or loss) ≥5% was considered significant. A logistic regression analysis was performed including sociodemographic and health-related variables.

Results: After adjusting, weight gain remained associated to disability (OR = 2.42; p = .027), whereas weigh loss lost significance (OR = 1.66; p = .384).

Discussion: Weight loss is generally considered more worrisome than weight gain in elderly. However, weight loss alone was not a risk factor for disability in our study.
