Longitudinal Improvements in Health‐Related Quality of Life Among Children Enrolled in the CANadian Paediatric Weight Management Registry ( CANPWR ) Over 3 Years
Authors' conclusion
Both child- and parent-reported HRQoL scores improved over 3 years, and these changes were associated positively with clinic attendance and negatively with unhealthy behaviours.
Study context
- Population
- Children with obesity enrolled in paediatric weight management programs, CANadian Paediatric Weight Management Registry (CANPWR), 2013–2020; 47.8% male; age 12.4 ± 3.3 years; BMI z-score 3.5 ± 1.2; 68.8% White615 (54%) at 3 years
- Participants
- 1,145 children
- Exposure
- Health-related quality of life (HRQoL) at baseline vs follow-up up to 3 years after enrolment in paediatric weight management programs (PWMP)
- Outcome
- Child (≥8 years) and parent-reported HRQoL (PedsQL4.0)
- Follow-up
- Baseline, 6-month, 1-, 2- and 3-year post-baseline

p < 0.001
Observational data: associations, not effects.
Further findings
Factors associated with total child-reported HRQoL
- Boys (ß)
- 2.71, CI: 1.2-4.2; p < 0.01
- Non-White (ß)
- 2.63, CI: 0.8-4.5; p < 0.01
- Higher household income (ß)

- Hours of clinic attendance (ß)
- 0.09 CI: 0.06-0.12; p < 0.01
- Sleep disturbance, lower physical activity and higher screen time associated with lower HRQoL
- Independent of BMI z-score
