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.
