背景：本研究的目的是评估为期 6 个月的干预措施，以通过计步器和电子邮件促进办公室员工步行。方法：参与者由 20 个工作场所的 10 个职业医疗保健单位 (OHC) 招募，共有 2,230 名员工。自愿且体力活动不足的员工 (N=241) 被随机分配到计步器组 (STEP, N=123) 和对照组 (COMP, N=118)。 STEP 包括一次小组会议、计步器使用日志监控以及来自 OHC 的六封电子邮件。 COMP参与数据收集。通过问卷调查（0、2、6、12 个月）、过程评估和访谈（12 个月）来评估影响范围、有效性、采用、实施、维护 (RE-AIM) 和成本。结果：就参与意愿而言，干预达到了 29% (N=646) 的员工。 Logistic 回归显示，2 个月时“步行交通”（比值比 2.12，95% CI 0.94 至 4.81）和 6 个月时“步行休闲”（1.86，95% CI 0.94 至 3.69）中，STEP 中步行者的比例往往比 COMP 中增加更多。线性模型显示，2 个月和 6 个月时“走楼梯”的平均持续时间略有增加（几何平均比 1.26，95% CI 0.98 至 1.61；1.27，0.98 至 1.64）。按照预期，通过和实施取得了成功。 12 个月时，15 个工作场所仍保留了一些干预痕迹，与 COMP 相比，STEP 中“步行楼梯”（OR 2.24，95% CI 0.94 至 5.31）和“步行休闲”（2.07，95% CI 0.99 至 4.34）中的步行者数量略多。干预的直接成本为每位参与者 43 欧元。结论：研究结果表明对某些步行指标的影响不大。未来的研究应该投资于接触员工、最大限度地减少流失率并使用客观的步行评估。
Background: The purpose of the study was to evaluate a 6-month intervention to promote office-employees' walking with pedometers and e-mail messages.Methods: Participants were recruited by 10 occupational health care units (OHC) from 20 worksites with 2,230 employees. Voluntary and insufficiently physically active employees (N=241) were randomized to a pedometer (STEP, N=123) and a comparison group (COMP, N=118). STEP included one group meeting, log-monitored pedometer-use and six e-mail messages from OHC. COMP participated in data collection. Reach, effectiveness, adoption, implementation, maintenance (RE-AIM) and costs were assessed with questionnaires (0, 2, 6, 12 months), process evaluation and interviews (12 months).Results: The intervention reached 29% (N=646) of employees in terms of participation willingness. Logistic regression showed that the proportion of walkers tended to increase more in STEP than in COMP at 2 months in "walking for transportation" (Odds ratio 2.12, 95% CI 0.94 to 4.81) and at 6 months in "walking for leisure" (1.86, 95% CI 0.94 to 3.69). Linear model revealed a modest increase in the mean duration of "walking stairs" at 2 and 6 months (Geometric mean ratio 1.26, 95% CI 0.98 to 1.61; 1.27, 0.98 to 1.64). Adoption and implementation succeeded as intended. At 12 months, some traces of the intervention were sustained in 15 worksites, and a slightly higher number of walkers in STEP in comparison with COMP was observed in "walking stairs" (OR 2.24, 95% CI 0.94 to 5.31) and in "walking for leisure" (2.07, 95% CI 0.99 to 4.34). The direct costs of the intervention were 43 Euros per participant.Conclusions: The findings indicate only modest impact on some indicators of walking. Future studies should invest in reaching the employees, minimizing attrition rate and using objective walking assessment.
