久坐对健康有害。我们描述了一项基于实践的研究，旨在减少久坐工作的工人长时间坐着并改善选定的健康因素。2011年3月至5月，我们在明尼苏达州的明尼阿波利斯市进行了这项研究，调查对象是从事久坐工作的员工。方法项目实施时间为7周，其中基线期1周（第1期），干预期4周（第2期），干预后2周（第3期）。干预组（n = 24）在第二阶段接受了一个适合他们工作站的站立装置，对照组（n = 10）没有。我们采用经验抽样的方法在项目的7周内监测工作中的坐着行为。我们根据调查结果估计了坐着时间、健康风险因素、情绪状态和几种办公室行为的变化分数。结果：站立项目将坐着的时间减少了224%（每天66分钟），将上背部和颈部疼痛减少了54%，并改善了情绪状态。此外，移除该装置在2周内基本上抵消了所有观察到的改善。我们的研究结果表明，在工作中使用坐立两用设备可以减少坐着的时间，并对员工的健康产生其他好处。
BackgroundProlonged sitting time is a health risk. We describe a practice-based study designed to reduce prolonged sitting time and improve selected health factors among workers with sedentary jobs. Community Context We conducted our study during March-May 2011 in Minneapolis, Minnesota, among employees with sedentary jobs.MethodsProject implementation occurred over 7 weeks with a baseline period of 1 week (period 1), an intervention period of 4 weeks (period 2), and a postintervention period of 2 weeks (period 3). The intervention group (n = 24) received a sitstand device during period 2 designed to fit their workstation, and the comparison group (n = 10) did not. We used experience-sampling methods to monitor sitting behavior at work during the 7 weeks of the project. We estimated change scores in sitting time, health risk factors, mood states, and several office behaviors on the basis of survey responses.OutcomeThe Take-a-Stand Project reduced time spent sitting by 224% (66 minutes per day), reduced upper back and neck pain by 54%, and improved mood states. Furthermore, the removal of the device largely negated all observed improvements within 2 weeks.InterpretationOur findings suggest that using a sit-stand device at work can reduce sitting time and generate other health benefits for workers.
