The average score of CTQ was 32.15±2.98;38.73% of the students were disregarded and only 2.22% of that were abused during their childhood. 40.00% of the students had no CTQ,1 kinds of CTQ accounted for 31.43% ,2 kinds of CTQ accounted for 18.25%,and more than 3 CTQ accounted for 10.32%. Multivariate logistic regression analysis show that gender(OR=1.034,95%CI:1.012-1.056),parents' marital status(OR=1.124,95%CI:1.087-1.162),family atmosphere(OR=1.025,95%CI:1.024-1.158),CTQ cumulative number(ORCTQ=1=1.528,95%CI:1.214-1.923;ORCTQ=2=3.067, 95%CI:1.325-7.102;ORCTQ≥3=10.361,95%CI:3.059-35.093) were the risk factors for depression.Conclusion Gender,parents' marital status,family atmosphere and CTQ cumulative number were risk factors for depression in adolescents.
