About this study

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.

Primary outcomes

  1. Proportion of passengers using the conventional stairs of the total number of passengers entering the subway station assessed using tally counters at the time of observation of subway entrance

    Time frame: Immediately at the time of subway entrance: at weeks 1 and 2 (baseline, pre-test), when street signs are posted at weeks 3 and 4, when street signs are posted with pop music at weeks 5 and 6, and without interventions at week 7 (post-test).

    Rate of passengers using the conventional stairs of the total number of passengers entering the subway station using tally counters at the time of observation of subway entrance

Secondary outcomes

  1. Proportion of male passengers using the conventional stairs of the total number of passengers entering the subway station assessed using tally countersat the time of observation of subway entrance

    Time frame: Immediately at the time of subway entrance: at weeks 1 and 2 (baseline, pre-test), when street signs are posted at weeks 3 and 4, when street signs are posted with pop music at weeks 5 and 6, and without interventions at week 7 (post-test).

    Rate of male passengers using the conventional stairs of the total number of passengers entering the subway station using tally counters at the time of observation of subway entrance

  2. Proportion of female passengers using the conventional stairs of the total number of passengers entering the subway station assessed using tally counters at the time of observation of subway entrance

    Time frame: Immediately at the time of subway entrance: at weeks 1 and 2 (baseline, pre-test), when street signs are posted at weeks 3 and 4, when street signs are posted with pop music at weeks 5 and 6, and without interventions at week 7 (post-test).

    Rate of female passengers using the conventional stairs of the total number of passengers entering the subway station using tally counters at the time of observation of subway entrance

  3. Proportion of minor passengers (under 18 years old) using the conventional stairs of the total number of passengers entering the subway station assessed using tally counters at the time of observation of subway entrance

    Time frame: Immediately at the time of subway entrance: at weeks 1 and 2 (baseline, pre-test), when street signs are posted at weeks 3 and 4, when street signs are posted with pop music at weeks 5 and 6, and without interventions at week 7 (post-test).

    Rate of minor passengers (under 18 years old) using the conventional stairs of the total number of passengers entering the subway station using tally counters at the time of observation of subway entrance

  4. Proportion of adult passengers (aged 19-65 years old) using the conventional stairs of the total number of passengers entering the subway station assessed using tally counters at the time of observation of subway entrance

    Time frame: Immediately at the time of subway entrance: at weeks 1 and 2 (baseline, pre-test), when street signs are posted at weeks 3 and 4, when street signs are posted with pop music at weeks 5 and 6, and without interventions at week 7 (post-test).

    Rate of adult passengers (aged 19-65 years old) using the conventional stairs of the total number of passengers entering the subway station using tally counters at the time of observation of subway entrance

  5. Proportion of senior passengers (aged over 65 years old) using the conventional stairs of the total number of passengers entering the subway station assessed using tally counters at the time of observation of subway entrance

    Time frame: Immediately at the time of subway entrance: at weeks 1 and 2 (baseline, pre-test), when street signs are posted at weeks 3 and 4, when street signs are posted with pop music at weeks 5 and 6, and without interventions at week 7 (post-test).
