Abstract:

This systematic review analyzed the prevalence of physical inactivity, sedentary behaviors, and unhealthy food habits among Brazilian adolescents. Searches were performed using five databases (LILACS, SciELO, MEDLINE, Web of Science, and the Google Scholar) and in the references cited by retrieved articles. The literature search yielded 5,872 titles of potentially relevant articles; a total of 69 studies met all inclusion criteria. The risk behavior most often evaluated was physical inactivity (48/69; 69.6%), and its prevalence rate ranged from 2.3% to 93.5%. Twenty-eight studies estimated physical inactivity prevalence above 50%. Most studies observed higher physical inactivity prevalence in girls. The prevalence of sedentary behaviors (high screen time or TV use) was also frequently above 50%. Several outcomes were used to identify unhealthy food habits, and some criteria/studies have indicated unhealthy food habits estimates in close to 100% of the adolescents. In conclusion, the estimates of these risk behaviors among Brazilians adolescents were very close to or even greater than those found in developed countries in several studies analyzed in this review.
