Background: It is critical to understand patient-reported outcomes in pediatric patients enrolled in pediatric weight management (PWM) clinics. Health-related quality of life (HRQoL) is low in children with obesity. Utilizing data from the CANadian Pediatric Weight Management Registry (CANPWR), we examined (1) changes in HRQoL up to 3 years after enrollment in PWM and (2) factors associated with change in HRQoL over time.
Methods: Child-reported (n=957) and parent-proxy reported (n=1111) HRQoL were assessed (PedsQL) at baseline, 6, 12, 24 and 36 months after commencing the PWM program at one of 9 Canadian PWM centers. Associations between demographic, anthropometric, lifestyle behavior and health services characteristics and HRQOL were assessed over 36 months using a linear effects model.
Results: Child self-reported and parent-proxy PedsQL total scores (74.6 +14.5 vs 69.9+15.2; P<0.001 and 68.6+17.0 vs 64.6+17.4; P<0.001 respectively) and the scores for each domain (physical, emotional, social and school functioning) improved from baseline. In multivariable models, self-reported total PedsQL score over time was higher in boys, children who identified as non-white, and those with higher household incomes. Lower scores were associated with sleep disturbance, lower physical activity, and higher screen time, independent of BMI z-score. Scores were higher in those with higher hours of clinic attendance. Similar factors predicted parent-proxy scores.
Conclusion: Self-reported and parent-proxy reported HRQoL improved over time in children enrolled in CANPWR. Higher self-reported scores were positively related to the amount of time in PWM clinics. Poor sleep, lower physical activity and higher screen time were associated with poorer HRQoL.
