Examine the effects of an interactive environmental intervention on stair usage.
A nonrandomized, quasi-experimental intervention.
Two three-story office buildings.
Approximately 200 employees at the intervention site and 140 at the comparison site.
The stairwell was decorated with interactive paintings such as maps, storyboards, and wish lists to encourage employees to take the stairs rather than the elevator.
Daily stair and elevator usage were measured using electronic sensors or door-access card counters for 2 weeks prior to the intervention and 6 weeks after.
The daily counts of stair use were modeled using a Poisson regression to estimate the effect of the intervention on staircase use.
At baseline, the mean proportion of stair use relative to stair plus elevator use at the intervention site was 31.5% (95% confidence interval [CI], 30.3%-32.7%). During the 6-week intervention period, this proportion increased significantly to 66.2% (95% CI, 64.4%-67.9%). There was no significant change in stair use at the comparison site. In a Poisson regression of the daily number of stair users, the incidence rate ratio associated with the intervention was 2.57 (95% CI, 2.35-2.82).
This interactive environmental intervention increased stair usage in an office setting relative to the comparison site, and this increase was sustained over a 6-week period. Adding interactive components to motivational or environmental change interventions shows promise in increasing stair usage.
研究交互式环境干预对楼梯使用的影响。
非随机、准实验干预。
两座三层办公大楼。
干预现场约 200 名员工和比较现场 140 名员工。
楼梯间用互动式壁画装饰，如地图、故事板和愿望清单，以鼓励员工走楼梯而不是乘电梯。
在干预前 2 周和干预后 6 周内，使用电子传感器或门禁卡计数器每天测量楼梯和电梯的使用情况。
使用泊松回归模型对楼梯使用的日常计数进行建模，以估计干预对楼梯使用的影响。
在基线时，干预现场楼梯使用相对于楼梯加电梯使用的平均比例为 31.5%（95%置信区间[CI]，30.3%-32.7%）。在 6 周的干预期间，这一比例显著增加到 66.2%（95% CI，64.4%-67.9%）。比较现场的楼梯使用率没有明显变化。在每日楼梯使用者数量的泊松回归中，与干预相关的发病率比为 2.57（95% CI，2.35-2.82）。
与比较现场相比，这种交互式环境干预增加了办公环境中楼梯的使用，并且这种增加在 6 周的时间内持续存在。在激励或环境变化干预中添加互动组件有望增加楼梯的使用。
