Dichotomous outcome measures	OR (group variable)^b	95% CI	P (group variable)
Dutch physical activity norms^a
Compliance with DNHPA	2.0	0.9–4.3	0.08

Physical activity by intensity

CI Confidence interval, OR Odds ratio
^aDutch physical activity norms:
- DNHPA Dutch Norm for Health-enhancing Physical Activity: Thirty minutes or more of at least moderate-intensity aerobic (endurance) physical activity on at least five days each week
- Fit-norm: Twenty minutes or more of vigorous-intensity physical activity on at least three days each week
- Combi-norm: Meeting the DNHPA and/or Fit-norm
^bTo test between-group changes in physical activity, multiple (logistic or linear) regression analyses were performed. Physical activity level at six months was the dependent variable and group (the control group served as reference category) was the independent variable. Corrections were made for baseline physical activity levels
^cUnstandardized regression coefficient
*Significant (p < 0.05) difference in physical activity between groups
