独立于身体活动水平，青少年久坐行为（SB）对健康有负面影响。一天中任意时段的SB患病率估计（例如，（d）在放学后，告知需要有针对性的特定时期的干预措施。本系统性综述旨在确定儿童和青少年在放学后的SB患病率。2015年10月进行了计算机检索（2015年11月分析）。入选标准为：发表在同行评议的英文期刊上;参与者年龄为5-18岁;客观地测量总体放学后久坐时间（ST），和/或具体的放学后SB（例如，电视观看）客观或主观;并提供了在ST/SB或行为持续时间和期间度过的课后时间的百分比来计算这一点。在可能的情况下，按地点分析结果（例如，课后照顾/“其他”地点）。遵循PRISMA指南。纳入了29项研究：24项包括儿童（≤12岁），4项评估青少年（>12岁），1项包括两者; 20项评估ST，9项评估SB。平均而言，儿童在课后护理和其他地点分别花费41%和51%的课后时间在ST中。青少年花了57%的课后时间在ST. SB儿童和青少年执行包括：看电视（周期的20%），非基于屏幕的SB（包括家庭作业; 20%），基于屏幕的SB（包括看电视; 18%），家庭作业/学术（13%），机动交通（12%），社交SB（9%）和基于屏幕的SB（不包括看电视; 6%）。儿童放学后有一半时间在ST，青少年的比例更高。放学后进行各种基于筛查和非筛查的SB，为干预提供关键目标。PROSPERO注册号CRD 42015010437本文的在线版本（doi：10.1186/s12966-016-0419-1）包含补充材料，可供授权用户使用。
Independent of physical activity levels, youth sedentary behaviors (SB) have negative health outcomes. SB prevalence estimates during discretionary periods of the day (e.g., after-school), inform the need for targeted period-specific interventions. This systematic review aimed to determine children’s and adolescents’ SB prevalence during the after-school period. A computerized search was conducted in October 2015 (analysed November 2015). Inclusion criteria were: published in a peer-reviewed English journal; participants aged 5-18 years; measured overall after-school sedentary time (ST) objectively, and/or specific after-school SBs (e.g., TV viewing) objectively or subjectively; and provided the percentage of the after-school period spent in ST/SB or duration of behavior and period to calculate this. Where possible, findings were analyzed by location (e.g., after-school care/‘other’ locations). The PRISMA guidelines were followed. Twenty-nine studies were included: 24 included children (≤12 years), four assessed adolescents (>12 years) and one included both; 20 assessed ST and nine assessed SB. On average, children spent 41 % and 51 % of the after-school period in ST when at after-school care and other locations respectively. Adolescents spent 57 % of the after-school period in ST. SBs that children and adolescents perform include: TV viewing (20 % of the period), non-screen based SB (including homework; 20 %), screen-based SB (including TV viewing; 18 %), homework/academics (13 %), motorised transport (12 %), social SB (9 %), and screen-based SB (excluding TV viewing; 6 %). Children spent up to half of the after-school period in ST and this is higher among adolescents. A variety of screen- and non-screen based SBs are performed after school, providing key targets for interventions.
