Analyses included participants from BIKE, MOD, and VIG who were included in per protocol analyses. Data are shown as unstandardized regression coefficients (β) (95% CI). aPresented as percentage points. Sleep duration variability and sleep midpoint variability were calculated as the sum of the absolute differences between the mean and each night of measurement divided by the number of nights measured. Adiposity variables were dependent variables in the multiple regression analyses, which were adjusted for age, gender, specific adiposity and sleep variables at baseline, and intervention group. BIKE, active commuting group; ESS, Epworth Sleepiness Scale; MOD, moderate intensity exercise group; PSQI, Pittsburgh Sleep Quality Index; VIG, vigorous intensity exercise group; WC, waist circumference.
