Objective:To investigate the risk factors for college students with non-suicidal self-injury(NSSI)in Chongqing. Methods:Data from 9 808 students were analyzed in a cross-sectional fashion. General characteristic

life event scale(LES)

Modified Overt Aggression Scale(MOAS)between NSSI and non-NSSI were compared. A multiple logistic regression model was used to identify risk factors for NSSI. Results:The incidence rate of NSSI was 3.7‰. There were significant differnces in sex behavior(P=0.034)

LES(P=0.001)

MAOS(P=0.000)between control and students with NSSI. Multiple logistic analysis shaowed that independent risk factors for NSSI were physical aggression(OR=3.12

95%CI=1.420 to 6.872)

confliction between lovers or couples(OR=4.56

95%CI=2.267 to9.180)

study problem(OR=2.59

95%CI=1.313 to 5.117). Conclusion:Physical aggression

confliction between lovers or couples

study problem are the independent risk factors for students with NSSI.
