aLeast-square means adjusted for age, median personal income, gender, and province.
bCohen f2≥0.02, ≥0.15, and ≥0.35 representing small, medium, and large effect sizes, respectively. For the engagement subgroup analysis only, Cohen f2 was calculated for the pre-post difference in steps between the low and high engagement groups (high engagement as the referent group).
cThe difference between baseline and week 12 were statistically significant at P<.001 for total sample and all subgroup analyses, except for Province Newfoundland and Labrador (P<.001).
