This cluster-randomized controlled trial evaluated the effectiveness of technology-assisted programs in replacing sedentary time (ST) with physical activity (PA) among Indian office workers. A total of 136 sedentary workers were randomized into two intervention groups: technology-assisted (SMART) and self-directed (TRADE), along with a control group. The SMART group used a smartphone app featuring hourly exercise video prompts and a pedometer, while the TRADE group received a wellness manual with strategies for reducing ST and increasing PA. ST and PA levels were assessed using accelerometers at baseline, 3 months, and 6 months. The SMART group showed a marginal reduction in ST (∼6 min/day) at 3 months (β = -0.340, p = 0.015) and 6 months (β = 0.114, p = 0.030). But the improvements were not sustained at 6 months in TRADE group (β = 0.105, p = 0.064). A significant decline in compliance (n = 57, 63 %) in both intervention groups. Future trials should incorporate organizational-level strategies to enhance compliance.
这项整群随机对照试验评估了技术辅助项目在印度上班族中用身体活动（PA）替代久坐时间（ST）的有效性。共有136名久坐不动的上班族被随机分为两个干预组：技术辅助组（SMART）和自主指导组（TRADE），还有一个对照组。SMART组使用一款具有每小时锻炼视频提示功能的智能手机应用程序和一个计步器，而TRADE组收到一本包含减少久坐时间和增加身体活动策略的健康手册。在基线、3个月和6个月时使用加速度计评估久坐时间和身体活动水平。SMART组在3个月时（β = -0.340，p = 0.015）和6个月时（β = 0.114，p = 0.030）久坐时间略有减少（约6分钟/天）。但TRADE组在6个月时改善未持续（β = 0.105，p = 0.064）。两个干预组的依从性均显著下降（n = 57，63%）。未来的试验应纳入组织层面的策略以提高依从性。
