Sedentary behavior in Brazilian children and adolescents: a systematic review

ABSTRACT OBJECTIVE To describe the methodological characteristics of the studies selected and assess variables associated with sedentary behavior in Brazilian children and adolescents. METHODS For this systematic review, we searched four electronic databases: PubMed, Web of Knowledge, LILACS, SciELO. Also, electronic searches were applied in Google Scholar. A supplementary search was conducted in the references lists of the included articles and in non-indexed journals. We included observational studies with children and adolescents aged from three to 19 years developed in Brazil, presenting analyses of associations based on regression methods and published until September 30, 2014. RESULTS Of the 255 potential references retrieved by the searches, 49 met the inclusion criteria and composed the descriptive synthesis. In this set, we identified a great number of cross-sectional studies (n = 43; 88.0%) and high methodological variability on the types of sedentary behavior assessed, measurement tools and cut-off points used. The variables most often associated with sedentary behavior were “high levels of body weight” (in 15 out of 27 studies; 55.0%) and “lower level of physical activity” (in eight out of 16 studies; 50.0%). CONCLUSIONS The findings of this review raise the following demands to the Brazilian agenda of sedentary behavior research geared to children and adolescents: development of longitudinal studies, validation of measuring tools, establishment of risk cut-offs, measurement of sedentary behavior beyond screen time and use of objective measures in addition to questionnaires. In the articles available, the associations between sedentary behavior with “high levels of body weight” and “low levels of physical activity” were observed in different regions of Brazil

Racial inequalities in access to women's health care in southern Brazil Desigualdades raciais no acesso à saúde da mulher no Sul do Brasil

The aim of this population-based cross-sectional study was to investigate access by 20 to 60 year-old women - both black and white - to early detection (pap-smear) exams for breast and cervical cancer in two towns - São Leopoldo and Pelotas - in Rio Grande do Sul State, southern Brazil. Estimates of the association between race/color and access to pap-smear and breast exams were adjusted for income, education, economic class and age. Of the 2,030 women interviewed, 16.1% were black and 83.9%, white. Black women were significantly less likely to have had a pap-smear and/or breast exam than white women. Racial inequalities in access to cancer early detection exams persisted after controlling for age and other socioeconomic factors. Racial differentials in access to early detection (pap-smear) exams for breast and cervical cancers might result from racial and socioeconomic inequalities experienced by black women in access to reproductive health care services and programs.<br>O objetivo da pesquisa foi investigar o acesso de mulheres negras e brancas aos exames de detecção precoce de câncer de mama e colo de útero (citopatológico), em duas cidades no Sul do Brasil. Foi realizado um estudo transversal de base populacional realizado com mulheres de 20-60 anos, residentes em São Leopoldo e Pelotas, Rio Grande do Sul, Brasil. As análises foram ajustadas por renda, escolaridade, classe econômica e idade para verificar a associação entre raça/cor e acesso aos exames. Foram entrevistadas 2.030 mulheres, sendo que 16,1% eram negras e 83,9% brancas. A probabilidade das mulheres não realizarem os exames citopatológico e de mama foi significantemente maior nas negras. A desigualdade racial no acesso aos exames de detecção precoce de câncer persistiu após controle para idade e variáveis socioeconômicas. O diferencial na realização dos exames de detecção precoce pode ser um reflexo das desigualdades raciais e socioeconômicas vividas por mulheres negras no acesso aos serviços e ações de atenção à saúde reprodutiva
