医生被期望成为健康生活方式的榜样，但长时间的工作会减少健康行为的时间。以医院为基础的身体活动干预可以改善医生的健康并增加有关运动的咨询。我们对马萨诸塞州波士顿一家大型医院的 104 名住院医师进行了两阶段干预。第一阶段是一项为期 6 周的随机对照试验，比较分配给显示步数和能量消耗反馈的活动监测器（干预）或盲态监测器（对照）的居民的每日步数。第二阶段紧随其后，是为期 6 周的非随机团队步数竞赛，所有参与者都佩戴带有反馈的监视器。第一阶段的结果是：1) 中位步数/天和 2) 佩戴活动监测器的天数比例。第 2 阶段的结果是佩戴监测器的天数的平均步数/天（≥500 步/天）。在基线和研究结束时收集生理测量结果。使用 Wilcoxon 秩和检验比较每天的中位步数。使用重复测量回归分析来比较平均步数。在第一阶段，干预组和对照组的活动相似（6369 步/天与 6063 步/天，p = 0.16）和佩戴监测器的依从性（77% 与 77% 天数，p = 0.73）。在第二阶段（团队竞赛）中，居民每天记录的步数比第一阶段多（对照：7,971 vs. 7,567，p = 0.002；干预：7,832 vs. 7,739，p = 0.13）。与第 1 阶段相比，第 2 阶段两组佩戴活动监测器的平均依从性均有所下降（60% vs. 77%，p<0.001）。与基线相比，研究结束时所有参与者的平均收缩压下降（p = 0.004），HDL 胆固醇升高（p<0.001）。尽管活动监测仪干预并未对活动或健康产生重大影响，但忙碌居民的高参与率以及步数、血压和高密度脂蛋白的适度变化表明，更深入的基于医院的健康计划有可能促进医生更健康的生活方式。临床试验.gov NCT01287208。
Physicians are expected to serve as role models for healthy lifestyles, but long work hours reduce time for healthy behaviors. A hospital-based physical activity intervention could improve physician health and increase counseling about exercise. We conducted a two-phase intervention among 104 medical residents at a large hospital in Boston, Massachusetts. Phase 1 was a 6-week randomized controlled trial comparing daily steps of residents assigned to an activity monitor displaying feedback about steps and energy consumed (intervention) or to a blinded monitor (control). Phase 2 immediately followed and was a 6-week non-randomized team steps competition in which all participants wore monitors with feedback. Phase 1 outcomes were: 1) median steps/day and 2) proportion of days activity monitor worn. The Phase 2 outcome was mean steps/day on days monitor worn (≥500 steps/day). Physiologic measurements were collected at baseline and study end. Median steps/day were compared using Wilcoxon rank-sum tests. Mean steps were compared using repeated measures regression analyses. In Phase 1, intervention and control groups had similar activity (6369 vs. 6063 steps/day, p = 0.16) and compliance with wearing the monitor (77% vs. 77% of days, p = 0.73). In Phase 2 (team competition), residents recorded more steps/day than during Phase 1 (Control: 7,971 vs. 7,567, p = 0.002; Intervention: 7,832 vs. 7,739, p = 0.13). Mean compliance with wearing the activity monitor decreased for both groups during Phase 2 compared to Phase 1 (60% vs. 77%, p<0.001). Mean systolic blood pressure decreased (p = 0.004) and HDL cholesterol increased (p<0.001) among all participants at end of study compared to baseline. Although the activity monitor intervention did not have a major impact on activity or health, the high participation rates of busy residents and modest changes in steps, blood pressure, and HDL suggest that more intensive hospital-based wellness programs have potential for promoting healthier lifestyles among physicians.
