Abstract P287: Weight misperception and health-related quality of life in Appalachian adolescents
Objective: Weight misperception (overestimation and underestimation) has been linked to health behaviors and overestimation in particular has been associated with higher psychological distress. Less is known about the relation between weight misperceptions and health-related quality of life (HRQoL) particularly among adolescents in Southern Appalachia.
Hypothesis: We assessed the hypothesis that weight misperception would be associated with poorer HRQoL outcomes.
Methods: Waves 1 (n=544) and 2 (n=965) baseline data collected between 2011-2012 were used from the Team Up for Healthy Living Project, a cluster-randomized trial targeting obesity prevention in adolescents through a cross-peer intervention among Appalachian school children. BMI percentiles for age and sex were calculated using measured height and weight. Participants were classified into 3 groups: (1) accurate weight perception (perceived weight corresponds with actual weight), (2) underestimators (perceived weight less than actual weight), and (3) overestimators (perceived weight more than actual weight). HRQoL was assessed using the 23-item Pediatric QoL Inventory 4.0 (PedsQLTM). Multiple linear regression was performed with adjustment for age, gender, race/ethnicity and BMI to examine associations between weight misperception and HRQoL.
Results: In total, 393 students (26.7%) underestimated their weight and 67 overestimated their weight (4.6%). Univariate analyses showed that compared to accurate perception, underestimation was associated with higher HRQoL in the following areas: total HRQoL score, physical health, psychosocial health, and emotional and social domains (all p<0.05); and overestimation was associated with a lower total HRQoL score and physical health, as well as emotional functioning (all p<0.05). After adjusting for covariates, compared to accurate perception, underestimation was associated with a higher total HRQoL score (β=2.73, P=0.002), physical health (β=3.09, P=0.001), and psychosocial health (β=2.62, P=0.008), as well as emotional (β=3.23, P=0.011) and social (β=2.79, P=0.011) functioning.
Conclusion: Contrary to the hypothesized relationship, underestimation was associated with higher HRQoL across all domains except for school functioning among Appalachian adolescents; whereas, overestimation was not associated with HRQoL. Better understanding of these associations will be beneficial in developing interventions to improve adolescents’ health in Appalachia.
