Physical activity (PA) is a health behavior that most Americans do not participate in at recommended levels.
We sought to increase PA by use of motivational signs in selected buildings. Because physical environments are known to influence PA, the relationship of building characteristics and stair usage was also assessed. One pre- and two post-intervention observations were conducted.
The proportion of those using the stairs increased from baseline to the second data collection, (chi2 = 39.31, p < 0.01) and baseline to a final data collection (chi2 = 10.1, p < 0.01). Built environment factors, including steps to the next higher floor and the number of floors in the building were consistent predictors of stair use. With signs positioned, the visibility of the stairs while standing in front of elevators became a significant predictor of stair usage.
Motivational signs and characteristics of built environments are associated with increased stair usage.
体育活动（PA）是一种健康行为，但大多数美国人并未达到推荐水平。
我们试图通过在选定建筑中使用激励标志来增加体育活动。由于已知物理环境会影响体育活动，因此还评估了建筑特征与楼梯使用之间的关系。进行了一次干预前观察和两次干预后观察。
从基线到第二次数据收集，使用楼梯的比例增加（卡方 = 39.31，p < 0.01），从基线到最终数据收集也增加（卡方 = 10.1，p < 0.01）。建筑环境因素，包括到上一层的步数和建筑物的层数，是楼梯使用的一致预测因素。设置标志后，站在电梯前时楼梯的可见性成为楼梯使用的重要预测因素。
激励标志和建筑环境特征与楼梯使用增加有关。
