Comportamento sedentário em universitários: uma revisão sistemática

Abstract

Studies on sedentary behavior (SB) among university students have been published, and the knowledge about the methods adopted in surveys is important for science, and the characterization of prevalence and associated factors are essential in the context of health policies for this population group. Thus, the aim of the present study was to describe prevalence, associated factors, and the methodological characteristics used in SB research among university students. A search in the National Library of Medicine (PUBMED), Scientific Electronic Library Online (SciELO), Virtual Health Library (VHL) and SCOPUS databases was performed. This study adopted the items and recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA), and the articles selected were analyzed according to their methodological characteristics, as well as prevalence and factors associated with SB. Of the 1,740 articles found in databases, 23 were included in this review. The prevalence for sitting time was from 34.0% to 90.2%. The use of operational definitions and cutoff points diversified, as well as the use of various instruments to estimate SB. The lack of standardization between cutoff points for SB determination and operational definitions, such as the use of non-validated instruments, was observed. Among factors associated with higher prevalence, the most prominent were overweight and depressive symptoms. It was concluded that the prevalence of SB was high in domains not related with the time devoted to studies and biological and psychological characteristics represented attributes more associated with SB.
