Sample size for each analysis is presented in online supplemental file 2. The estimate of each exposure represents the average change in outcome (i.e., IRR for frequency of out-of-home food purchasing, and number of servings for fruit and vegetables intake) for a one-unit (i.e., 1 hour) within-individual change in exposure.
*Models adjusted for age, education, household composition, remoteness, neighbourhood socioeconomic status and work schedule.
Coef., coefficient; IRR, incidence rate ratio.
