Move for Life (MFL) is a theory-informed intervention that was developed to augment established physical activity (PA) programmes and enable inactive adults aged 50 years and older to be more active. This study examined the feasibility of MFL and sought to provide evidence of its potential for improving PA and associated health outcomes.
A 3-arm cluster randomised feasibility trial compared MFL intervention, usual provision (UP) and control (CON) groups at baseline (T0), post-intervention (T1, at 8, 10 or 12- weeks) and 6-month follow up (T2). We used purposive sampling strategies to recruit participants according to characteristics of interest. Feasibility outcomes assessed recruitment, fidelity, adherence, retention and data completion rates based on pre-set criteria. Primary outcomes were accelerometer-based moderate-to-vigorous intensity PA (MVPA) and self-reported compliance with physical activity guidelines (PAGL). Secondary outcomes included light intensity PA (LiPA), standing time, sedentary time, body composition (adiposity), physical function and psychological well-being. We used linear mixed models (continuous outcomes) or generalized estimated equations (categorical outcomes) to estimate group differences over time in the study outcomes.
Progression criteria for feasibility outcomes were met, and 733 individuals were recruited. Considering a 6-month period (T0-T2), while self-reported compliance with PAGL increased in MFL relative to UP and CON and in UP relative to CON, standing time decreased in MFL relative to CON and sedentary time increased in the latter compared to UP. Waist circumference decreased in MFL relative to UP and CON. MFL outperformed UP in the Timed Up and Go Test while MFL and UP increased the distance covered in the Six-Minute Walk Test compared to CON. Psychological well-being increased in MFL relative to CON (all < 0.05).
Findings show that MFL is feasible, while data are promising with regards to the potential of improving community PA programmes for adults aged 50 or more years.
“行动起来（Move for Life，MFL）”是一个基于理论的干预措施，旨在增强现有的体育活动（PA）项目，并使 50 岁及以上的不活跃成年人更加活跃。本研究旨在检验 MFL 的可行性，并寻求证据表明其有潜力改善 PA 和相关健康结果。
一项 3 臂整群随机可行性试验比较了 MFL 干预组、常规提供组（UP）和对照组（CON）在基线（T0）、干预后（T1，在 8、10 或 12-14 周）和 6 个月随访（T2）时的情况。我们根据感兴趣的特征使用有针对性的抽样策略招募参与者。可行性结果根据预先设定的标准评估招募、保真度、依从性、保留率和数据完成率。主要结局是基于加速度计的中等到剧烈强度 PA（MVPA）和自我报告的遵守体力活动指南（PAGL）。次要结局包括低强度 PA（LiPA）、站立时间、久坐时间、身体成分（肥胖）、身体功能和心理健康。我们使用线性混合模型（连续结局）或广义估计方程（分类结局）来估计研究结局在时间上的组间差异。
可行性结果的进展标准得到满足，共招募了 733 名参与者。考虑到 6 个月的时间（T0-T2），虽然 MFL 组自我报告的 PAGL 遵守情况相对 UP 和 CON 组有所增加，而 UP 组相对 CON 组有所增加，但 MFL 组的站立时间相对 CON 组减少，而 MFL 组的久坐时间相对 UP 组增加。与 UP 和 CON 相比，MFL 组的腰围减少。MFL 在计时起立行走测试中优于 UP，而 MFL 和 UP 组在 6 分钟步行测试中覆盖的距离均高于 CON。与 CON 相比，MFL 组的心理健康状况有所改善（均 P<0.05）。
研究结果表明，MFL 是可行的，同时，数据显示，改善 50 岁及以上成年人社区 PA 项目的潜力是有希望的。
