aInternational Physical Activity Questionnaire (IPAQ).
bAll participants had measured variables including 2 participants who did not complete baseline self-report surveys.
cModel coefficients and P values were obtained from analysis of covariance models adjusting for baseline values, general practitioner clinic, and gender. Robust regression models were used for analyses where residuals indicated nonnormality. Missing baseline and follow-up values were imputed to create five datasets and results were pooled using Rubin’s rules.
