UPnGO with ParticipACTION (UPnGO) is a 6-week workplace physical activity (PA) initiative aiming to increase habitual PA (steps) during the workday. Core intervention components included (1) self-monitoring of steps and action planning behaviours using a Web/mobile app with incentives and (2) organizational support, which included senior management's role modeling and endorsement of the program.
What is the effectiveness and levels of implementation of the UPnGO intervention? What is the relationship between effectiveness and levels of implementation?
A single-arm, pre-/post-test study design was used. Participants were 660 employees from nine organizations who had valid step data and complete socio-demographic information at baseline. The primary outcome (mean daily steps) was assessed by Garmin VivoFit. Using the usage data from the UPnGO web-based system, a composite score for levels of implementation was calculated based on participant's compliance with the self-monitoring component and senior management's role modeling. Associations of interest were analyzed using linear mixed-effects models.
Levels of implementation were highly variable across organizations (mean = 68.22% ± 18.75, range = 19.8 to 100%). A significant Time × Implementation (IM) status interaction effect was observed. When stratified by IM status, a significant increase in mean daily steps at week 6 was found among participants in the high (β = 540.01 ± 202.69, p = 0.011) but not low (β = - 81.54 ± 291.96, p = 0.78) implementation group.
Findings suggest significant intervention effects in increasing average daily steps among participants who were exposed to optimal levels of implementation (~ 70%). UPnGO may be a scalable workplace PA intervention at a national level, although this needs further verification with more rigorous study designs.
UPnGO 与 ParticipACTION（UPnGO）是一项为期 6 周的工作场所体力活动（PA）计划，旨在增加工作日期间的习惯性 PA（步数）。核心干预措施包括：（1）使用带有激励措施的网络/移动应用程序自我监测步数和行动计划行为；（2）组织支持，包括高级管理人员对该计划的示范和认可。
UPnGO 干预措施的效果和实施水平如何？效果与实施水平之间的关系是什么？
采用单臂、前后测试设计。共有来自 9 家组织的 660 名员工参加了这项研究，这些员工在基线时具有有效的步数数据和完整的社会人口统计学信息。主要结果（平均每日步数）由 Garmin VivoFit 评估。使用 UPnGO 网络系统的使用数据，根据参与者对自我监测部分的遵守情况和高级管理人员的示范作用，计算实施水平的综合得分。使用线性混合效应模型分析感兴趣的关联。
各组织之间的实施水平差异很大（平均为 68.22%±18.75%，范围为 19.8%至 100%）。观察到时间与实施（IM）状态之间存在显著的交互效应。当按 IM 状态分层时，在高实施水平（β=540.01±202.69，p=0.011）而非低实施水平（β=-81.54±291.96，p=0.78）参与者中，第 6 周的平均每日步数显著增加。
研究结果表明，在接触到最佳实施水平（约 70%）的参与者中，该干预措施在增加平均每日步数方面具有显著效果。UPnGO 可能是一种可在全国范围内推广的工作场所 PA 干预措施，但需要更严格的研究设计进一步验证。
