Data are presented as the mean (SD), except for the sex group*. BMI, body mass index; CIRS-G, Cumulative Illness Rating Scale for Geriatrics; SPPB, Short Physical Performance Battery. aThe most prevalent diseases were coronary, pulmonary, genitourinary, and neurologic diseases. bThe CIRS-G scale evaluates individual body systems, ranging from 0 (best) to 56 (worst). cThe SPPB scale ranges from 0 (worst) to 12 (best). dMMSE, The Mini-Mental State Examination ranges from 0 (worst) to 30 (best). eThe Barthel Index ranges from 0 (severe functional dependence) to 100 (functional independence)
