Avaliação da atividade física na promoção da saúde de adolescentes brasileiros: revisão sistemática

Objective: To analyze the methodological designs of national studies that assessed the level of physical activity for promoting adolescent health. Methods: a systematic literature review of original researches and publications of MEDLINE, LILACS, SCOPUS and ADOLEC electronic databases. It focused on determinant aspects of physical activity for health promotion using the following keywords: physical activity, physical fitness, physical activity, physical exercise, motor activity, sedentary and sedentariness, adolescent, adolescence, young, youth, teenager, and teenage, Brazil, Brazilian, South America, Low-middle income and country(ies). Data analysis covered the period from 2005 to 2011. First, 449 studies were identified. After analyzing the titles of the manuscripts, 130 articles were eligible for abstract evaluation and subsequent full text analysis. In the end, 31 articles met all inclusion criteria. Results: A total of 93.6% (n=29) of the evaluated studies used cross-sectional design, with samples ranging from 92 to 5028 subjects, and all of them used questionnaires for measuring physical activity. The main analysis of the studies was based on the association between physical activity, biodemographic data (age, gender) and socioeconomic data (income, social class and parental education). Conclusion: The national studies assessing the level of physical activity for promoting adolescent health appear with great methodological variability since there is no standardization in the methodological design, instrument and definition of variables, highlighting the need for longitudinal studies in this area. doi:10.5020/18061230.2013.p426
