Beyond Posters: Stairtember-Evaluating the Effectiveness of a Multicomponent Intervention to Promote Stair Climbing.

OBJECTIVE

Although stair climbing could contribute to daily physical activity goals, and there is potential for broad population reach, most stair climbing interventions are single-component and have limited effect.

METHODS

In a longitudinal quasiexperimental study, a 1-month multicomponent intervention, followed by 6 months with point-of-choice prompts, was evaluated in a six-story university building. All floors climbed and lifts ascended were measured by infrared people counters. Regular building occupants were invited to participate in the Stairtember Challenge intervention component.

RESULTS

During the intervention, stair climbing increased by 15%. Stair to lift ratios increased from 0.46 to 0.56 (odds ratio 1.22; 95% confidence interval 1.18 to 1.27).

CONCLUSIONS

The multicomponent stair climbing intervention achieved a moderate increase in average daily stair climbing and stair to lift ratio. As these effects are larger than previously found for traditional signage-based interventions, future interventions should go beyond posters for larger effects on population health.
