DUMITH, Samuel C.. Physical activity in Brazil: a systematic review. Cad. Saúde Pública [online]. 2009, vol.25, suppl.3, pp.S415-S426. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2009001500007.
The purpose of this study, based on a systematic literature review, was to describe the prevalence of physical activity (or inactivity) in the Brazilian population. The databases consulted were: LILACS, SciELO, MEDLINE, Web of Science, and the Google Scholar portal. The terms "physical activity", "physical exercise", "physical inactivity", "sedentary" "Brazil", and "Brazilian" were used in the search. Overall, 47 studies (all cross-sectional) with random samples were found, and in 26 studies physical activity was the main variable. Only two studies were published before the year 2000, as compared to 12 in 2008 alone. The studies were heavily concentrated in the South and Southeast of Brazil, and there were few studies on physical activity in children and adolescents. In all the studies, physical activity was measured subjectively, mainly with questionnaires, and the most widely studied domain was leisure time. The criteria for defining physical activity varied widely, as did prevalence. The study highlighted the need for standardization of instruments, criteria, and nomenclature in epidemiological studies on physical activity.
