Abstract: Objective To study the association between depressive symptoms and obesity among primary school students,in order to provide evidence for interventions on childhood obesity and mental health. Methods A cross-sectional survey was conducted in 12 primary schools of Dongcheng district in Beijing. A total of 1 412 students in Grade 3 to 5 were selected to self-report depressive symptoms through Childhood Depression′s Inventory (CDI). Students′ nutritional status was classified based on Chinese standards. The t tests,Pearson chi-square tests and linear mixed model were used to analyze the relationship between depression scores,body mass index (BMI) and BMI-Z,depressive symptoms and obesity,and to know about whether gender and depressive symptoms had additive effects on obesity. Results The average score of depressive symptoms was 9.75±6.38 in 1 412 participants aged 7 to 11 years. The prevalence rates of students with depressive symptoms were 13.1% and 6.7% for boys and girls,respectively. And 28.6% of students with depressive symptoms were obese,while it was 18.7% in students without depressive symptoms,and the difference was significant (P<0.05). After adjusting school,age and gender,BMI and BMI-Z increased by 0.04 (95%CI:0.01-0.07) and 0.01(95%CI:0.001-0.020)when depression scores increased by 1. Compared with students without depressive symptoms,the risk of developing obesity among students with depressive symptoms rose significantly (OR=1.54,95%CI:1.03-2.29). The combined effect of gender and depressive symptoms on obesity was found to be significant. Conclusions Depressive symptoms are associated with obesity in children. More attention should be paid to mental health in obese children,and it is suggested to give high-risk children psychological intervention
