All data are presented as odds ratio (95 % confidence interval). Models 1 and 3: adjusted for gender, age, anthropometric data (weight, height, waist circumference, body mass index, total fat mass), Barthel and Lawton indexes, risk of depression, and drug use. Models 2 and 4: also adjusted for frailty. Differences were always considered to be statistically significant when p ≤ 0.05
