Research has shown the effectiveness of sedentary behaviour interventions on reducing sedentary time. However, no systematic review has studied where the reduced sedentary time after such interventions is displaced to.
Our objective was to synthesize the evidence from interventions that have reduced sedentary behaviour and test the displacement of sedentary time into physical activity (light physical activity [LPA], moderate-to-vigorous physical activity [MVPA], standing, and stepping).
Two independent researchers performed a systematic search of the EBSCOhost, PubMed, Scopus, and Web of Science electronic databases. Meta-analyses were performed to examine the time reallocated from sedentary behaviour to physical activity during working time and the whole day in intervention trials (randomized/non-randomized controlled/non-controlled).
A total of 36 studies met all the eligibility criteria and were included in the systematic review, with 26 studies included in the meta-analysis. Interventions showed a significant overall increase in worksite LPA (effect size [ES] 0.24; 95% confidence interval [CI] 0.05 to 0.43; P < 0.013) and daily LPA (ES 0.62; 95% CI 0.34 to 0.91; P = 0.001). A statistically significant increase in daily MVPA was observed (ES 0.47; 95% CI 0.26 to 0.67; P < 0.001). There was a significant overall increase in worksite standing time (ES 0.76; 95% CI 0.56 to 0.95; P < 0.001), daily standing time (ES 0.52; 95% CI 0.38 to 0.65; P < 0.001), and worksite stepping time (ES 0.12; 95% CI 0.04 to 0.20; P = 0.002).
Effective interventions aimed at reducing sedentary behaviour result in a consistent displacement of sedentary time to LPA and standing time, both at worksites and across the whole day, whereas changes in stepping time or MVPA are dependent on the intervention setting. Strategies to reduce sedentary behaviour should not be limited to worksite settings, and further efforts may be required to promote daily MVPA.

研究表明，习惯行为干预可有效减少久坐时间。但尚无系统综述研究过这些干预措施减少的久坐时间转移到了何处。
本研究旨在综合减少习惯行为的干预措施证据，并检验久坐时间转移到体力活动（低强度体力活动[LPA]、中高强度体力活动[MVPA]、站立和踏步）的情况。
两名独立研究人员对 EBSCOhost、PubMed、Scopus 和 Web of Science 电子数据库进行了系统检索。对在工作时间和全天进行的干预试验（随机/非随机对照/非对照），进行荟萃分析以检验从习惯行为重新分配到体力活动的时间。
共有 36 项研究符合所有入选标准，并纳入系统综述，其中 26 项研究纳入荟萃分析。干预措施显示，工作场所 LPA（效应量[ES]0.24；95%置信区间[CI]0.05 至 0.43；P<0.013）和日常 LPA（ES 0.62；95%CI 0.34 至 0.91；P=0.001）整体显著增加。观察到日常 MVPA 显著增加（ES 0.47；95%CI 0.26 至 0.67；P<0.001）。工作场所站立时间（ES 0.76；95%CI 0.56 至 0.95；P<0.001）、日常站立时间（ES 0.52；95%CI 0.38 至 0.65；P<0.001）和工作场所踏步时间（ES 0.12；95%CI 0.04 至 0.20；P=0.002）整体显著增加。
针对减少习惯行为的有效干预措施可一致地将久坐时间转移到 LPA 和站立时间，无论是在工作场所还是全天，而踏步时间或 MVPA 的变化则取决于干预设置。减少久坐行为的策略不应仅限于工作场所，可能需要进一步努力促进日常 MVPA。
