Of the 122 randomised adolescents, 95 completed all questionnaires at baseline. Table 1 presents anthropometric and demographic characteristics of these 95 study participants. No significant differences were found in baseline characteristics between Go4it and control group, nor between the 95 study participants and the 27 adolescents who did not fill in the baseline questionnaires.

Physical and psychosocial well-being
Physical and psychosocial well-being scores and between group differences at 6 and 18 months follow-up are presented in Table 2. At baseline, participants experienced lower levels of physical and psychosocial well-being scores compared with a healthy reference group from Engelen et al. (PedsQLTM4.0) (26) and Raat et al. (CHQ) (27). At the 18 months follow-up, we found small but beneficial intervention effects on all subscales of the PedsQLTM4.0 and BES questionnaires. Two subscales of the PedsQLTM4.0 improved significantly, i.e. physical health (between group difference 5.4; 95% CI: 0.3; 10.6) with a clinical effect size of 0.7, and school functioning (between group difference 7.4; 95% CI: 1.6; 13.2), with a clinical effect size of 0.3. We found effect modification by sex and ethnicity on a few HRQoL outcomes. The results were inconsistent and for this are the reason not presented.
