Workplaces are important settings for interventions to increase physical activity, but effects have been modest.
To evaluate the efficacy of Move to Improve, a social-ecologic intervention delivered at the workplace to increase leisure-time physical activity.
A group-randomized 12-week intervention consisting of organizational action and personal and team goal-setting was implemented in Fall 2005, with a multi-racial/ethnic sample of 1442 employees at 16 worksites of The Home Depot, Inc. Change in physical activity was analyzed in Fall 2007 using latent growth modeling and latent transition analysis.
Participants in the intervention had greater increases in moderate and vigorous physical activity and walking compared to participants in a health education control condition. The proportion of participants that met the Healthy People 2010 recommendation for regular participation in either moderate or vigorous physical activity remained near 25% at control sites during the study but increased to 51% at intervention sites. During the last 6 weeks of the study, intervention participants exceeded 300 weekly minutes of self-reported moderate-to-vigorous physical activity and 9000 daily pedometer steps.
The results support the feasibility and efficacy of the Move to Improve intervention and the role of goal-setting for attaining increased physical activity levels.
工作场所是增加身体活动干预措施的重要实施环境，但效果一直不太显著。
评估“行动起来，改善健康”这一社会生态干预措施在工作场所实施以增加休闲时间身体活动的效果。
2005年秋季实施了一项为期12周的群组随机干预，包括组织行动以及个人和团队目标设定，样本为家得宝公司16个工作地点的1442名多种族/民族员工。2007年秋季使用潜在增长模型和潜在转变分析对身体活动的变化进行了分析。
与健康教育对照组的参与者相比，干预组参与者在中等强度和剧烈身体活动以及步行方面的增加幅度更大。在研究期间，对照地点达到《健康人民2010》中定期参与中等强度或剧烈身体活动建议的参与者比例在25%左右，但干预地点这一比例增至51%。在研究的最后6周，干预组参与者自我报告的每周中等至剧烈身体活动超过300分钟，每日计步器步数超过9000步。
结果支持“行动起来，改善健康”干预措施的可行性和有效性，以及目标设定在提高身体活动水平方面的作用。
