dc.description.abstractIntroduction: Many studies analyze body composition changes in older adults. However, few studies analyze body composition in elderly people with functional measures. Studies using Double X-Ray analysis (DXA) or Bioimpedance analysis proved to be reliable but expensive or only possible in a laboratory environment. The purpose of our study was to analyze changes in body composition over three years using anthropometric measures in a sample of elderly people in order to perceive functional changes. Methods: Forty-three participants (12 men; 31 women) aged 60 years and over and independent in activities of daily life were assessed using anthropometric measures in the first moment and past three years. Weight, height, waist and hip circumference were measured, and body mass index (BMI) and waist-to-hip ratio (WHR) were also calculated. Skeletal muscle mass (SMM) was also calculated using Al-Gindan et al. (2014) equations and normalized for height to found skeletal muscle index (SMI) in order to analyze cut-off points associated with physical disability according to Janssen et al (2004). Results: A significant difference was found over three years in SMM (p = 0.007), SMI (p = 0.027), BMI (p = 0.041) and WHR (p = 0.003). The majority of the participants has decreased SMM, SMI, and BMI and increased WHR, which favors a worst prognostic for comorbidities associated with these variables, and a tendency for sarcopenic obesity seems to be present although more studies are needed. Also, we found that using cut-off points for disability risk 83.3% of the men and 38.7% of the women of our sample were at moderate or high risk of disability. Three years later this percentage has increased but only for women to 54.8%. Conclusions: Although men are at risk of disability, women quickly lose their functional capacity, making necessary a rapid intervention to reduce the risk of disability in this population.pt_PT
