[Trends in body fat and muscle mass among elderly individuals in Fortaleza, Ceará State, Brazil].

The aim of this study was to describe trends in body fat and muscle mass among elderly individuals in Fortaleza, Ceará State, Brazil. This was a population-based, cross-sectional, household survey of elderly individuals (> 60 years) (n = 483) in Fortaleza. The variables analyzed were: triceps skinfold thickness (TST), upper arm fat area (UFA), mid upper arm circumference (MAC), arm muscle circumference (AMC), arm muscle area (AMA), and corrected arm muscle area (CAMA). Mean TST and UFA were significantly higher in women than men (p < 0.05). Mean AMC, AMA, and CAMA were higher in men than women (p < 0.05). For all the variables, the mean and 50th percentile decreased with age, except the TST percentile for women. Anthropometric and body composition patterns in the elderly in this study showed similar trends to those of other studies, but with different values. The values could thus be useful as references for the elderly in Fortaleza.
