My Wellness Begins With the Steps! / Mi Bienestar se Inicia en Los Peldaños! (Mi BIP!) N-of-1 Pilot Trial

This study evaluates the effect of street signs inviting to use the conventional stairs instead of escalators at a subway station without and with active pop music.

Detailed Description

Physical inactivity is a major contributor to chronic diseases worldwide, and promoting incidental physical activity in daily settings may help improve population health. This study evaluates whether street signs encouraging subway users to choose conventional stairs over escalators increase stair use, and whether the addition of active pop music further enhances this effect. Passengers entering selected subway stations will be counted to measure the proportion choosing stairs versus escalators under different conditions. The study compares stair use at a station exposed first to signage alone and then to signage combined with music to assess strategies that may promote physical activity in daily life. The project will be implemented for 1 hour of high subway station trafic, between 5:30 and 7:30pm, during a the same day of the week for 7 consecutive weeks. Weeks 1 and 2 will be baseline assessments. Weeks 3 and 4 will assess stair use with signage only, and weeks 5 and 6 will assess stair use with signage and music. Week 7 will assess stair use without an intervention promoting its use.
