The US government initiated a national health campaign targeting 100 'small step' lifestyle changes to combat obesity. Small Step #67 advocates stair instead of escalator usage in public settings. The aim of this study is to evaluate the effects of motivational signs prompting stair use over escalator use on pedestrians' stair usage in commuter settings. Eight studies, testing the effects of motivational prompts on stair vs. escalator usage in public settings, were reviewed. Participant and study attributes were descriptively coded. Effect size was calculated as the change in percent units of stair users during the intervention phases vs. the baseline phase. The average study included approximately 45,000 observations that were recorded across an average of 15 weeks of intervention. The mean +/- SD change in percent units of stair users was 2.8% +/- 2.4% (P < 0.001), and effects were twice as large in females (4.8%) as in males (2.4%). The number of stairs/building, baseline stair use, and total intervention weeks predicted change in stair use, although the effects were clinically miniscule. In a hypothetical city intervention, we projected that a 2.8% increase in stair usage would result in a weight loss and/or weight gain prevention of 300 g/person/year among new stair users. In sum, point-of-decision motivational signs may help communities attain Small Step #67. However, the singular impact of this community intervention on correcting energy imbalance may be minimal, having slight impact itself on reducing the national obesity prevalence.
OBJECTIVE: To investigate whether signs encouraging taking the stairs or discouraging taking the elevator lead to an increasing number of patients taking the stairs instead of the elevator in a hospital. DESIGN: Interventional study. METHOD: During a period of 6 weeks in the period October-December 2004, an investigator recorded how many patients took the stairs and how many took the elevator on the first floor of a hospital close to a diabetes outpatient clinic. A baseline measurement was done over a period of 2 weeks and 4 weeks were used for evaluating the effect of 2 different interventions, each lasting 2 weeks. During the first intervention, a sign was hung up near the elevator, which read: 'Exercise is healthy, take the stairs'. During the second intervention the sign read: 'Use of this elevator is exclusively for personnel and persons with restricted mobility'. Staff members and disabled patients were excluded from the study. RESULTS: A total of 2674 movements were counted. Use of the stairs increased statistically significantly during both interventions: from 54.6% to 63.4% during the first intervention and to 70.4% during the second intervention. CONCLUSION: Signs in a diabetes outpatient clinic that either encouraged the use of the stairs or discouraged the use of the elevator increased the patients' use of the stairs.
BACKGROUND: Despite strong evidence that prompts at the point of choice between escalators and stairs encourage stair use, the long-term effects of stair prompts have not yet been investigated. Presented here are the results of a 6-month observational study of prompted stair climbing. METHODS: Escalator and adjacent stair use were monitored in a shopping mall in the Midlands region of the United Kingdom. Participants were coded for gender, age, and ethnicity. A 2-week baseline period was followed by a 12-week intervention using motivating messages on the stair risers. Follow-up data were also collected for 2 weeks immediately after the removal of the banners and 6 weeks later. RESULTS: A total of 45,361 escalator/stair-choice observations were made. Stair use increased significantly during the intervention period and, when the banners were removed, remained higher than at baseline. There were also significant interactions with time across the different population groups. CONCLUSIONS: The full public health benefits of increasing physical activity levels can only be realized if the activity is sustained. These results demonstrate that stair-riser banners can elicit a sustained increase in stair use and, even when the banners were withdrawn, overall stair use remained higher than at baseline.
