Maintenance of the Rate of Stair Use over a Long-term Period Using a Stair Climbing Campaign

Abstract

Objective: This study was a long-term survey of a stair climbing campaign that made use of point-of-choice prompts aimed at achieving exemplary behavior in citizens. Methods: The campaign began in September 2007 at the Kochi Prefectural Office. We monitored office workers who climbed the stairs or used the elevator in the prefectural office building, excluding weekends, from August 2007 through February 2009. Prompts were placed on the stair risers. A total of 59 days were monitored during the observation period. A questionnaire was distributed to 250 workers to examine the influence of the prompts following completion of the observation period. Results: A total of 16,583 observations of the choice of workers to use the elevators or stairs were made during the observation period. The mean number of stair users was 281.0 ± 66.0 per day. Stair use increased significantly from 31.5 to 58.1% among women and from 26.3 to 62.4% among men during months 1–3 of the campaign. Stair use was maintained in more than 51% of women and 60% of men during the entire campaign period. The following response (valid records: 81) was given by 10% of the respondents regarding the use of stairs: “my use of stairs increased due to the message banners”. Conclusions: The stair climbing campaign was effective for increasing stair use and was maintained over a long-term period. However, most office workers thought that their increased stair use was not due to prompts placed on risers; therefore, the reason for the increased stair use remains unclear.(J Occup Health 2014; 56: 511–518)
