 abstract={Objectives: The aim of the study was to assess the relationship between body composition, nutritional status and physical ability in elderly outpatients. Method:. In this cross-sectional study, demographic data and medical history were collected from patients aged ≥60 years followed in the Geriatric Outpatient Clinic from October 2010 to February 2014. Body composition was examined using a dual-energy X-ray absorptiometry. Physical performance was assessed by gait speed (GS), Timed Up & Go Test (TUG), Six Minute Walk Test (6MWT). The nutritional status was evaluated using the Mini Nutritional Assessment (MNA) and serum albumin level. Results: Mean age (± SD) of 76 patients (64.47% men) was 71.93 ± 8.88 yrs. The most common diseases were: hypertension (89.47%), coronary heart disease (81.58%) and chronic heart failure (68.4%). In multiple regression analyses, the factors significantly affecting GS were: age (B = –0.017, p ≤0.0001), good nutritional status (B = 0.038, p <0.01) and percent of lower extremity fat (B = –0.009, p <0.05). Longer TUG time was associated with poorer nutritional status (B = –0.031, p <0.01), older age (B = 0.01, p <0.01) and a higher number of comorbidities (B = 0.034, p <0.05). 6MWT was influenced negatively by age (B = –3.805, p <0.01) and percent of lower extremity fat (B = –2.474, p <0.05). Conclusions: Age and nutritional status remain a strong determinant of physical fitness deterioration. Different measures of physical performance are influenced by different elements of body composition — no single element of body composition was found determining the deterioration of all assessed parameters of physical fitness. Identifying the relationship between body composition, nutritional status and physical performance can help elucidate the causes of disability and target preventive measures.},
