描述所选研究的方法学特征，并评估与巴西儿童和青少年久坐行为相关的变量。 对于本系统评价，我们检索了四个电子数据库：PubMed，Web of Knowledge，LILACS，SciELO。此外，还在Google Scholar中进行了电子检索。在纳入文献的参考文献列表和未编入索引的期刊中进行补充检索。我们纳入了在巴西开展的3至19岁儿童和青少年的观察性研究，基于回归方法进行了相关性分析，并于2014年9月30日发表。 在通过检索检索到的255篇潜在参考文献中，49篇符合纳入标准并构成描述性综合。在这一组中，我们确定了大量的横断面研究（n = 43; 88.0%）和高的方法学差异的类型久坐行为评估，测量工具和使用的截止点。最常与久坐行为相关的变量是“高水平的体重”（27项研究中有15项; 55.0%）和“低水平的体力活动”（16项研究中有8项; 50.0%）。 本次审查的结果提出了以下要求，以适应儿童和青少年的久坐不动的行为研究的巴西议程：纵向研究的发展，验证的测量工具，建立风险截止，久坐不动的行为测量超出屏幕的时间和使用的客观措施，除了问卷调查。在现有的文章中，在巴西不同地区观察到久坐行为与“高水平体重”和“低水平体力活动”之间的关联。
To describe the methodological characteristics of the studies selected and assess variables associated with sedentary behavior in Brazilian children and adolescents. 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. 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%). 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.
