SUMMARY:

Sarcopenia is a syndrome characterized by reduced muscle mass, muscle strength, and physical performance. It is considered one of the main causes of disability in the elderly, which implies impairments in functional capacity and quality of life. Factors such as decreased protein synthesis, proteolysis, changes in neuromuscular integrity, and fat content may be involved in its genesis. The aim of this study was to evaluate sarcopenia and sarcopenic obesity in the elderly by relating them to anthropometric and bioelectric parameters. This is a cross-sectional study nested in a cohort, of the 3rd wave of the International Mobility in Aging Study - IMIAS Brasil project in 2016, with the participation of 169 elderly people. Anthropometric and bioelectric data were collected to assess nutritional status. Such data were used to calculate the body mass index (BMI) and the skeletal muscle mass index (SMMI), related to low muscle mass, strength and physical performance to obtain the diagnosis of sarcopenia; lean mass index (LMI) and fat mass index (FMI) to identify sarcopenic obesity; the phase angle (PA) for the vector analysis of bioelectrical impedance (BIVA), which was performed by BIVA software 2002. Among the elderly participants, 14.8% had sarcopenia and 13.6% sarcopenic obesity. Regarding the anthropometric nutritional status, 7.1% were underweight and 69.8% were overweight and obese and 89.4% of the elderly were found to be at high risk for cardiovascular disease. The elderly with sarcopenia and sarcopenic obesity had lower BMI and perimeter values of the arm, calf, and muscle of the arm than those who did not have these conditions (p <0.05). LMI values were lower for those with sarcopenia and sarcopenic obesity (p <0.001, for both sexes). The PA values were lower for men with sarcopenia and sarcopenic obesity (p <0.003 and p <0.021, respectively). In the analysis stratified by sex, according to the BIVA, groups of elderly people with sarcopenia and with sarcopenic obesity had longer vectors when compared to the others (p <0.0001). When plotting the individual vectors, reduced cell mass was observed in 71% of women with sarcopenia, and 88% with sarcopenic obesity. For men, we detected reduced cell mass in 36% of those with sarcopenia and in 33% of those who had sarcopenic obesity. In conclusion, individuals with sarcopenia or sarcopenic obesity had lower values of anthropometric parameters related to the muscularity and a bioelectric nutritional profile with impaired cellularity.
