Objective: Examined body weight misperception and its association with health-related factors among South Korean adolescents.
Design and Methods: The 2009 Korea Youth Risk Behavior Web-based Survey data from 72,399 adolescents aged 12-18 years were used. Based on agreements between weight status assessed according to self-reported BMI and self-perceived weight status, adolescents were classified as weight underestimate, accurate, and overestimate. Logistic regression models examined the associations controlling for covariates.
Results: Over 50% adolescents misclassified their own weight status: underestimation (23.4%) and overestimation (26.8%). Boys had a higher underestimation rate than girls (30.3% vs. 15.6%) and a lower overestimation rate (21.3% vs. 33.0%). Ingirls,overestimation was higher in high-income familes and well-educated parents (41.0%). Compared to those with accurate weight perception, participants who underestimated their weight were more likely to have an unhealthy diet as indicated by higher daily consumption (once/day) of fast food [OR ¼ 1.18 (1.00, 1.39)] and unhealthy snacks [OR ¼ 1.11 (1.03,1.19)]. Girls who overestimated their weight had more screen time [2 h/day, OR ¼ 1.12 (1.03,1.22)]. Participants who overestimated their weight were more likely to be stresse[OR ¼ 1.24 (1.18, 1.31)] anddepressed [OR ¼ 1.18 (1.21, 1.25)].
Conclusions: Over half of Korean adolescents had misperception on own weight status, the rates varied by gender and socioeconomic status. Weight misperception is associated with health-related outcomes compared to peers with accurate perceptions about own weight status.
