Association and Discriminatory Power of Abdominal Obesity for the Prevention of Sarcopenia and Vice Versa in Postmenopausal Women

Both abdominal obesity and sarcopenia are associated with cardiometabolic disorders mainly in postmenopausal women. In addition, there appears to be a reverse association between abdominal obesity and sarcopenia. The objective of the study was to identify the association and the discriminatory power of abdominal obesity for the prevention of sarcopenia and vice versa in postmenopausal women. The sample includes 257 women with age 57,2 years, The abdominal obesity and the variables determinants of sarcopenia were assessed by bioelectrical impedance analysis. The association of variables was been tested using logistic regression and the discriminatory power through Receiver Operating Characteristic (ROC) considering a confidence interval of 95%. The presence of abdominal obesity with the cutoff point of 153 cm2 of visceral fat was discriminatory power for sarcopenia, as well as the musculoskeletal mass index with the cuttof point of 35,2% discriminated the absence of abdominal obesity. After adjusting for confounders it was observed still association between abdominal obesity and sarcopenia and association between musculoskeletal mass index and absence of abdominal obesity. The results of the study suggest that abdominal obesity discriminates and is associated with sarcopenia, such as musculoskeletal mass index discriminates the absence and is inversely associated whit of abdominal obesity in postmenopausal women
