Sedentary behaviour has emerged as a unique determinant of health in adults. Studies in children and adolescents have been less consistent. We reviewed the evidence to determine if the total volume and patterns (i.e. breaks and bouts) of objectively measured sedentary behaviour were associated with adverse health outcomes in young people, independent of moderate-intensity to vigorous-intensity physical activity. Four electronic databases (EMBASE MEDLINE, Ovid EMBASE, PubMed and Scopus) were searched (up to 12 November 2015) to retrieve studies among 2- to 18-year-olds, which used cross-sectional, longitudinal or experimental designs, and examined associations with health outcomes (adiposity, cardio-metabolic, fitness, respiratory, bone/musculoskeletal, psychosocial, cognition/academic achievement, gross motor development and other outcomes). Based on 88 eligible observational studies, level of evidence grading and quantitative meta-analyses indicated that there is limited available evidence that the total volume or patterns of sedentary behaviour are associated with health in children and adolescents when accounting for moderate-intensity to vigorous-intensity physical activity or focusing on studies with low risk of bias. Quality evidence from studies with robust designs and methods, objective measures of sitting, examining associations for various health outcomes, is needed to better understand if the overall volume or patterns of sedentary behaviour are independent determinants of health in children and adolescents.
久坐行为已成为成年人健康的一个独特决定因素。在儿童和青少年中的研究结果则不太一致。我们对相关证据进行了综述，以确定在考虑到中等到剧烈强度的身体活动的情况下，客观测量的久坐行为的总量和模式（即间断和持续时间）是否与年轻人的不良健康结果有关。我们在四个电子数据库（EMBASE MEDLINE、Ovid EMBASE、PubMed 和 Scopus）中进行了检索（截至 2015 年 11 月 12 日），以检索在 2 至 18 岁儿童中使用横断面、纵向或实验设计，并检查与健康结果（肥胖、心血管代谢、体能、呼吸、骨骼/肌肉骨骼、心理社会、认知/学业成绩、粗大运动发育和其他结果）之间关联的研究。基于 88 项符合条件的观察性研究，证据水平分级和定量荟萃分析表明，当考虑到中等到剧烈强度的身体活动或关注低偏倚风险的研究时，仅有有限的证据表明久坐行为的总量或模式与儿童和青少年的健康有关。需要采用设计和方法稳健、采用客观坐姿测量、针对各种健康结果进行关联分析的研究来提供高质量证据，以更好地了解久坐行为的总体量或模式是否是儿童和青少年健康的独立决定因素。
