Although studies have demonstrated that stair prompts are associated with increased physical activity, many were conducted in low-rise buildings over a period of weeks and did not differentiate between stair climbing and descent.
This study evaluated the impact of a prompt across different building types, and on stair climbing versus descent over several months.
In 2008-2009, stair and elevator trips were observed and analyzed at three buildings in New York City before and after the posting of a prompt stating "Burn Calories, Not Electricity" (total observations=18,462). Sites included a three-story health clinic (observations=4987); an eight-story academic building (observations=5151); and a ten-story affordable housing site (observations=8324). Stair and elevator trips up and down were recorded separately at the health clinic to isolate the impact on climbing and descent. Follow-up was conducted at the health clinic and affordable housing site to assess long-term impact.
Increased stair use was seen at all sites immediately after posting of the prompt (range=9.2%-34.7% relative increase, p<0.001). Relative increases in stair climbing (20.2% increase, p<0.001) and descent (4.4% increase, p<0.05) were seen at the health clinic. At both sites with long-term follow-up, relative increases were maintained at 9 months after posting compared to baseline: 42.7% (p<0.001) increase in stair use at the affordable housing site and 20.3% (p<0.001) increase in stair climbing at the health clinic.
Findings suggest that the prompt was effective in increasing physical activity in diverse settings, and increases were maintained at 9 months.
尽管已有研究表明，楼梯提示可提高身体活动量，但这些研究大多在低层建筑中进行，且持续时间为数周，并未区分爬楼梯和下楼梯。
本研究评估了提示在不同建筑类型中的影响，以及其在数月内对爬楼梯和下楼梯的影响。
2008-2009 年，在纽约市的三栋建筑中，在张贴了一条提示信息“燃烧卡路里，而非电力”之后，观察并分析了楼梯和电梯的使用情况（总观察次数=18462）。这些地点包括一栋三层的健康诊所（观察次数=4987）、一栋八层的学术楼（观察次数=5151）和一栋十层的经济适用房（观察次数=8324）。在健康诊所中，单独记录了楼梯和电梯上下的使用情况，以隔离对爬楼梯和下楼梯的影响。在健康诊所和经济适用房进行了随访，以评估长期影响。
提示发布后，所有地点的楼梯使用率均立即增加（相对增加范围为 9.2%-34.7%，p<0.001）。健康诊所中，爬楼梯（增加 20.2%，p<0.001）和下楼梯（增加 4.4%，p<0.05）的相对增加更为显著。在两个具有长期随访的地点中，与基线相比，发布后 9 个月的相对增加仍保持不变：经济适用房的楼梯使用率增加 42.7%（p<0.001），健康诊所的爬楼梯使用率增加 20.3%（p<0.001）。
研究结果表明，提示在不同环境中有效提高了身体活动量，且 9 个月后仍保持增加。
