There is increasing concern about the time young people spend in sedentary behaviour ('sitting time'), especially with the development of attractive home-based electronic entertainment. This may have deleterious health effects.
To ascertain, through a meta-analytic review, whether interventions targeted at reducing sedentary behaviours in young people are successful.
ERIC, MedLine, PsychInfo, SportDiscus and the Cochrane Library databases were searched up to 2010. Titles and abstracts of identified papers were examined against inclusion criteria. Included papers were coded by three researchers.
17 papers, including 17 independent samples (N=4976), met the inclusion criteria and were analysed. There was a small but significant effect in favour of sedentary behaviour reduction for intervention groups (Hedges' g = - 0.192; SE = 0.056; 95% CI = -0.303 to -0.082; p = 0.001). Moderator analyses produced no significant between-moderator results for any of the intervention or study characteristics, although trends were evident.
Behaviour change interventions targeting reductions in sedentary behaviour have been shown to be successful, although effects are small. More needs to be known about how best to optimise intervention effects.
年轻人久坐行为（“久坐时间”）的时间越来越受到关注，尤其是随着有吸引力的家庭电子娱乐的发展。这可能对健康有不良影响。
通过荟萃分析综述，确定针对减少年轻人久坐行为的干预措施是否有效。
截至 2010 年，检索了 ERIC、MedLine、PsychInfo、SportDiscus 和 Cochrane 图书馆数据库。对确定的论文的标题和摘要进行了检查，以确定是否符合纳入标准。纳入的论文由三位研究人员进行编码。
符合纳入标准并进行分析的论文有 17 篇，包括 17 个独立样本（N=4976）。干预组的久坐行为减少效果较小但有统计学意义（Hedges' g = - 0.192；SE = 0.056；95% CI = -0.303 至 -0.082；p = 0.001）。虽然趋势明显，但干预或研究特征的任何因素的调节分析均未产生显著的组间差异。
针对减少久坐行为的行为改变干预措施已被证明是有效的，尽管效果较小。需要更多地了解如何优化干预效果。
