Abstract

Objective
We aimed to investigate the cross-sectional and longitudinal relationship between body mass index (BMI), waist circumference, percent body fat (%BF), and weight status (overweight/obese) with health-related quality of life (QOL) in adolescents.

Methods
Of 2,353 children (median age 12.7 years) examined, 1,213 (51.7%) with complete data were resurveyed 5 years later, and an additional 475 adolescents were newly recruited. Weight, height, waist circumference, %BF, and body mass index were obtained and defined using standardized protocols. QOL was assessed using the Pediatric Quality of Life Inventory (PedsQL).

Results
In cross-sectional analyses, obese boys differed significantly from normal weight boys in the PedsQL physical summary only (multivariable-adjusted p = .005). Boys with the highest %BF (≥95th percentile) compared to their peers in the 6th to 94th percentiles had a significantly lower total PedsQL score (7.7-unit difference, p = .0003), and had adjusted mean scores: 7.92, 7.54, 7.35, 6.51, and 8.56 units lower in the physical summary (p = .0003), psychosocial summary (p = .004), emotional (p = .03), social (p = .02), and school (p = .04) domains, respectively. Nonsignificant cross-sectional associations were observed in girls. Adolescents who remained obese (n = 41) compared to those who were non-overweight/obese (n = 704) over the study period, had lower PedsQL physical summary score 5 years later: 85.6 versus 90.5 (p = .03). Conversely, individuals who were overweight/obese at baseline but who became non-overweight/obese at follow-up (n = 92), had significantly higher physical summary scores than those who remained obese 5 years later (n = 41), 91.4 versus 85.6 (p = .03).

Conclusion
Adiposity in adolescent boys, but not girls, was associated with poorer QOL.
