Two hundred and seventy-two sedentary women with a mean age of 66.75 ± 5.38 years were recruited for participation in this study. Obesity was determined by both body mass index and dual-energy X-ray absorptiometry (DXA) evaluations. Sarcopenic obesity diagnosis was established from the ratio between fat-free mass and body surface area as obtained by DXA. There was no association of obesity with sarcopenic obesity (P = 0.424). In contrast, sarcopenia was significantly related to sarcopenic obesity (P < 0.001), although most of the elderly women with sarcopenia (n = 171) did not exhibit sarcopenic obesity. These results highlight the importance of diagnosing sarcopenic obesity as elderly women exhibiting sarcopenia could be either eutrophic or obese.
