ObjectiveThe aim of this study was to evaluate the effects of the types and levels of physical activity in conjunction with protein intake and vitamin D on sarcopenia and obesity status in an elderly population.MethodsStudy participants (N = 4452) were ages ≥60 y and included 1929 men and 2523 women who completed a body composition analysis with a dual energy x-ray absorptiometry and provided health and dietary data.ResultsHigher appendicular skeletal muscle mass/weight was observed in the non-obese group, although obese participants had greater weights. The non-obese sarcopenia subgroup showed health problems related to insulin resistance and metabolic-related factors compared with the nonsarcopenic group. The total metabolic equivalent was significantly different in both obese categories, regardless of sarcopenic status. The prevalence of obesity, sarcopenia, and sarcopenic obesity relatively increased with a diet deficient of protein intake and vitamin D.ConclusionThese data suggest that sarcopenia had a significant association with metabolic-related factors; physical activity, especially vigorous activity; and protein intake and vitamin D levels in a non-obese elderly population. Therefore, maintaining healthy body weight by means of resistance exercise and enhanced protein intake and vitamin D may help offset sarcopenia in this age group.Copyright © 2016 Elsevier Inc.
