Proxy-reported HRQoL of overweight, normal-weight youth, and youth perceived as ‘too fat’ in the general population compared with the treatment sample. Note: 8–16 years old; N=6299 (KiGGS sample) and N=137 (Obeldicks light sample). *p≤0.05, ** p≤0.01., *** p≤0.001. Simple contrasts adjusted for sociodemographic differences and between-sample-point variation. Contrasts were performed within the described three-level hierarchical models but with other codes assigned to the compared groups.
