Sarcopenia is a progressive and generalized loss of skeletal muscle mass (SM) and function which can also be found in obese adults. The aim of the study was to evaluate the prevalence of sarcopenia in 1 245 obese women (18 - 67 years, weight 114.7±24.5 kg; BMI 44.1±9.2; fat mass 49.0±6.2%) from Southern Italy. Body composition was evaluated by bioimpedance analysis (BIA) and SM calculated by using Janssen's equation; therefore the sex-specific cut-off points of percentage skeletal muscle index were used. The whole population was divided in two age groups: A (18-40 years; n. 808; weight 115.4±23.5 kg; BMI 43.8±8.8 kg/m2) and B (41-67 years; n. 438; weight 113.4±26.3 kg; BMI 44.8±9.9 kg/m2). In all the sample there was 2.7% moderate and 0.6% severe sarcopenia; in group A, 1.9% moderate and 0.6% severe sarcopenia whilst in group B 4.3% moderate and 0.7% severe sarcopenia. The results of our study suggest that, based on a screening examination by BIA, moderate/severe sarcopenia can be detected in an unselected middle-aged obese population. Further studies are required to clarify the diagnosis with functional tests.
