Score and associated factors of depressive symptoms of adolescents through descriptive statistical analysis, Chi square test, analysis of variance and Logistic regression analysis.@*Results@#The detection rate of depressive symptoms among adolescents in a district of Chongqing was 17.3%, and the total score of depression scale was (12.02±6.72). There were statistically significant differences in the inefficiency subscale score of boys across stages of genital, pubic hair, armpit hair and beard, and whether the first spermatorrhea has occurred( t/F =7.08，5.46，5.18，4.21，5.84， P <0.05), while significant differences were found in the anhedonia and inefficiency subscales scores among girls across different stages of breast, pubic hair and armpit hair, and whether menarche has occurred( t/F =19.43，4.92，3.98，7.35， P <0.05). Multivariate Logistic regression analysis showed that the absence of first spermatorrhea and menarche were associated with lower prevalence of depressive symptoms in boys and girls ( OR=0.60, 95%CI=0.36-0.98; OR=0.46, 95%CI =0.22-1.00), while pubic hair development was associated with higher prevalence of depressive symptoms in girls ( OR=9.58, 95%CI =1.28- 71.71 ).@*Conclusion@#The detection rate of depressive symptoms among adolescents is relatively low. Boys who have had the first spermatorrhea, and girls with advanced pubic hair development or have had menarche are more likely to suffer from depressive symptoms.
