1)利用系统综述的信息，综合目前关于久坐行为与健康结果之间关联的观察证据。2)评估发现的系统评价的方法学质量。Medline;医学文摘（Embase）；PsycINFO;和Web of Science检索截至2013年9月发表的评论。其他出版物由久坐行为研究网络成员提供。使用AMSTAR推荐的标准标准评估系统评价的方法学质量。对于每个综述，在描述其主要结果/结论时不恰当地使用因果语言进行评估。总共有1044篇综述，144篇被完整阅读，27篇被收录。基于具有最佳方法学质量的系统评价，我们在儿童和青少年中发现了久坐行为与肥胖之间存在关系的有力证据。此外，在血压和总胆固醇、自尊、社会行为问题、身体健康和学业成绩方面也观察到适度的证据。在成年人中，我们发现了确凿的证据，证明久坐行为与全因死亡率、致命性和非致命性心血管疾病、2型糖尿病和代谢综合征之间存在关联。此外，有适度的证据表明卵巢癌、结肠癌和子宫内膜癌的发病率。这一综述基于现有的最佳系统综述，表明久坐行为可能是健康的重要决定因素，独立于身体活动。然而，这种关系是复杂的，因为它取决于久坐行为的类型和所研究的年龄组。久坐行为与许多健康结果之间的关系仍不确定；因此，有必要进行进一步的研究。
1) To synthesize the current observational evidence for the association between sedentary behavior and health outcomes using information from systematic reviews. 2) To assess the methodological quality of the systematic reviews found. Medline; Excerpta Medica (Embase); PsycINFO; and Web of Science were searched for reviews published up to September 2013. Additional publications were provided by Sedentary Behaviour Research Network members. The methodological quality of the systematic reviews was evaluated using recommended standard criteria from AMSTAR. For each review, improper use of causal language in the description of their main results/conclusion was evaluated. Altogether, 1,044 review titles were identified, 144 were read in their entirety, and 27 were included. Based on the systematic reviews with the best methodological quality, we found in children and adolescents, strong evidence of a relationship between time spent in sedentary behavior and obesity. Moreover, moderate evidence was observed for blood pressure and total cholesterol, self-esteem, social behavior problems, physical fitness and academic achievement. In adults, we found strong evidence of a relationship between sedentary behavior and all-cause mortality, fatal and non-fatal cardiovascular disease, type 2 diabetes and metabolic syndrome. In addition, there is moderate evidence for incidence rates of ovarian, colon and endometrial cancers. This overview based on the best available systematics reviews, shows that sedentary behavior may be an important determinant of health, independently of physical activity. However, the relationship is complex because it depends on the type of sedentary behavior and the age group studied. The relationship between sedentary behavior and many health outcomes remains uncertain; thus, further studies are warranted.
