ABSTRACT
Objective: To understand the association between body weight perception and suicide related behaviors among middle and high school students in Zhejiang Province, and to provide a basis for body weight management and suicide prevention. Methods: Based on the baseline survey data of the Zhejiang childhood behavior and health cohort, 7 666 subjects were included in this study the use multivariate logistic regression analysis to examine the association between body weight perception and accuracy with suicidal ideation and attempts, and OR with 95%CI were reported. Results: The proportions of feeling moderate, underweight, and overweight were 43.7%, 24.0%, and 32.3%, respectively. The rates of accurate, underestimated, and overestimated weight perception were 61.6%, 22.9%, and 15.5%, respectively. In the past 12 months, 18.4% of students had suicidal ideation, 4.9% had suicidal attempts. After adjustment for potential confounders, analysis results showed that the ORs for suicidal ideation and perceived underweight and overweight were 1.66 (95%CI: 1.40-1.97) and 1.36 (95%CI: 1.14-1.63), respectively; the ORs for suicidal ideation and underestimation and overestimation of body weight were 1.35 (95%CI: 1.15-1.58) and 1.32 (95%CI: 1.09-1.59), respectively. The ORs for suicidal attempts between perceived overweight, and overestimated weight were 1.34 (95%CI: 1.00-1.80) and 1.43 (95%CI: 1.05-1.93), respectively. There is no significant association between BMI and weight perception or weight perception accuracy. Conclusions: BMI is not associated with suicidal behavior. Both perceived overweight and underweight are positively correlated with suicidal ideation in students, while perceived overweight and overweight are positively correlated with suicidal attempts.
