Purpose:

To evaluate the uptake of ACT-i-Pass (G5AP), a physical activity (PA) intervention that provides free access to PA opportunities, and to understand the extent to which the intervention provides equitable access to children. Design:

This study evaluates the differences in uptake (ie, enrollment) by comparing postal codes of registrants with the postal codes of all eligible children. Setting:

Children were provided the opportunity to register for the G5AP during the 2014 to 2015 school year in London, Canada. Participants:

The population of grade 5 students in London who registered for the G5AP (n = 1484) and did not register (n = 1589). Intervention:

The G5AP offered grade 5 students free access to select PA facilities/programs during 2014 to 2015 school year. Measures:

Measures included G5AP registration status, method of recruitment, distance between home and the nearest facility, and neighborhood socioeconomic status. Analysis:

Getis-Ord Gi* and multilevel logistic regression were used to analyze these data. Results:

There were significant differences in the uptake of the G5AP: residing in neighborhoods of high income (odds ratio [OR] = 1.062, P = .029) and high proportion of recent immigrants (OR = 1.036, P = .001) increased the likelihood of G5AP registration. Children who were recruited actively were significantly more likely to register for the G5AP (OR = 2.444, P < .001). Conclusion:

To increase the uptake of a PA intervention, children need to be actively recruited. Interactive presentations provide children with increased access to information about both the program and its nuances that cannot be communicated as effectively through passive methods.
