Abstract

OBJECTIVE: To explore the relationship between distorted weight perception and suicide ideation among normal weight adolescents in Guangdong province. METHODS: This study used the data of Guangdong Provincial Youth Health Risk Behavior Survey in 2004 and 2007. To identify the association between distorted weight perception and suicide ideation, a logistic regression analysis was performed. The effects of age, economic status, mother's education, mental health, and depression were also adjusted. RESULTS: A total of 12 729 people participated in this study, 6096 males and 6633 females. The prevalence of suicide ideation among normal weight adolescents was 13.58% (1729/12 729) in the past 12 months, with higher prevalence in girls (16.15%, 1071/6633) than that in boys (10.79%, 658/6096) (χ(2) = 77.71, P = 0.00). It was common that the adolescents misperceived their weight. Only 44.93% (5719/12 729) of normal weight students correctly perceived their body weight while 43.52% (5540/12 729) of them overestimated their weight and 11.43% (1455/12 729) underestimated their weight. The distorted weight perception in girls (65.58%, 4350/6633) was higher than that in boys (43.39%, 2645/6096) (χ(2) = 993.91, P = 0.00). Distorted weight perception was significantly associated with suicide ideation after controlling for factors age, economic status, mother's education, mental health, and depression. The students who overestimate their body weight were more likely to have suicide ideation than that who correctly perceived their weight (OR = 1.43, 95%CI: 1.27 - 1.61). CONCLUSION: The prevalence of distorted weight perception was high and it significantly associated with suicide ideation.
