Increasing stair use in an office worksite through an interactive environmental intervention.

Abstract

PURPOSE:

Examine the effects of an interactive environmental intervention on stair usage.

DESIGN:

A nonrandomized, quasi-experimental intervention.

SETTING:

Two three-story office buildings.

SUBJECTS:

Approximately 200 employees at the intervention site and 140 at the comparison site.

INTERVENTION:

The stairwell was decorated with interactive paintings such as maps, storyboards, and wish lists to encourage employees to take the stairs rather than the elevator.

MEASURES:

Daily stair and elevator usage were measured using electronic sensors or door-access card counters for 2 weeks prior to the intervention and 6 weeks after.

ANALYSIS:

The daily counts of stair use were modeled using a Poisson regression to estimate the effect of the intervention on staircase use.

RESULTS:

At baseline, the mean proportion of stair use relative to stair plus elevator use at the intervention site was 31.5% (95% confidence interval [CI], 30.3%-32.7%). During the 6-week intervention period, this proportion increased significantly to 66.2% (95% CI, 64.4%-67.9%). There was no significant change in stair use at the comparison site. In a Poisson regression of the daily number of stair users, the incidence rate ratio associated with the intervention was 2.57 (95% CI, 2.35-2.82).

CONCLUSION:

This interactive environmental intervention increased stair usage in an office setting relative to the comparison site, and this increase was sustained over a 6-week period. Adding interactive components to motivational or environmental change interventions shows promise in increasing stair usage.
