نبذة مختصرة : The interest in the study of aging has been growing due to the increase in the number of elderly and also because they are independent. During the aging process, there are several changes, including those related to body composition, which may cause an increase in adipose and visceral tissue leading to the onset of obesity and may also muscle mass reduction and strength, contributing to the development of sarcopenia. The simultaneous occurrence of sarcopenia and obesity in the elderly, the condition called sarcopenic obesity may develop which can be associated with health problems and decreased quality of life. The present study aimed to determine the prevalence of sarcopenic obesity in Brazilian elderly. This is a systematic review with meta-analysis. The databases PubMed, LILACS, Scopus, Scielo were consulted. As inclusion criteria we selected articles that investigated sarcopenic obesity, published in Portuguese, English and Spanish from 2010, involving Brazilian elderly aged 60 years and over of both sexes. Dissertations, theses, experimental animal studies, in vitro studies, recommendations, guidelines, reviews, protocols, letters, editorials, case reports, case series and duplicates were excluded. We used the descriptors, sarcopenic obesity, elderly, Brazilians and Brazil and their correlates in English and Spanish. In order to evaluate the quality of the studies, the Newcastle Ottawa Scale was used. Statistical analysis was performed using R Studio 3.6.0 software, heterogeneity through I² statistics and presented in forest plot graph. The total of 12 studies were included in this study. The prevalence of Brazilian elderly with sarcopenic obesity was 15% (95% CI: 10-23%), with the highest prevalence found in the Midwest. A high heterogeneity was found in the general prevalence analyzes and subgroups (regions and criteria and diagnostic methods). A sensitivity analysis was performed omitting the extreme prevalence values found in the included studies, where a 3% reduction in the overall prevalence of ...
