FERREIRA DE MORAES, Augusto César; GUERRA, Paulo Henrique  and  ROSSI MENEZES, Paulo. The worldwide prevalence of insufficient physical activity in adolescents: a systematic review. Nutr. Hosp. [online]. 2013, vol.28, n.3, pp.575-584. ISSN 1699-5198.  https://dx.doi.org/10.3305/nh.2013.28.3.6398.

Objective: To perform a systematic review of cross-sectional studies on the prevalence of insufficient physical activity (IPA) based on a WHO-defined cutoff point (< 60 min/d of moderate and vigorous physical activity). Methods: The search was carried out using online databases (BioMed Central, CINAHL, EMBASE, ERIC, PsycInfo, PubMed MEDLINE, SCOPUS, SPORT-Discus), and included articles published from the beginning of the databases until February18^th, 2012, as well as references cited by the retrieved articles and information provided by the authors. Only original articles using questionnaires in the diagnosis were considered. Results: Of 2,384 papers initially retrieved, fifteen studies met the inclusion criteria, of which seven were conducted in Brazil. The prevalence of IPA varied from 18.7% to 90.6%, with a median of 79.7%. In all surveys, the prevalence was higher among girls than boys and the developing countries have higher prevalence. Conclusions: We concluded that the prevalence of IPA is high among adolescents and that the definition adopted in this study is rarely used in the literature. These results suggesting that is necessary the development of interventions for increasing physical activity levels among adolescents.
