  • Objective To investigate the prevalence and risk factors of non-suicidal self-injury among undergraduate students.Methods A total of 3 854 undergraduates in Nanchang were investigated by self-designed questionnaire,including memories of parental rearing practices in childhood,multidimensional sub-health questionnaire of adolescents,adolescent life events scale,and Ottawa self-injury scale.Results Among the 3 854 undergraduate students,393 (10.2%) were diagnosed as NSSI-positive.The most common forms of self-injury behavior included "bite force yourself"(52.9%),"pick or scratching themselves" (52.9%),"pulled his hair"(42.0%),with significant sex differences.More female students reported "bite force yourself",while male reported more on "stifled his immersionuried his head in the water","excessive or careless use of drugs","swallow or drink can't eat".Logistic regression analysis showed childhood maltreatment(OR =3.493),punished due to mistakes(OR =1.995),"nagging what I did in front of others made me feel embarrassed" (OR=1.835),non-biological mother,physical abuse(OR=1.651),being disgraced(OR=1.602),impulse to throw things(OR =1.601),academic failure(OR =1.553),often feel nervous (OR =1.527) were main risk factors for NSSI among undergraduates students.The NSSI behaviors of college students were statistically correlated with their suicidal ideation,suicidal plan and suicidal attempt.The OR values were 6.596(95%CI=4.915-8.850),7.769 95%CI=4.521-13.353) and 5.683 (95%CI=2.956-10.927).Conclusion Non-suicidal self-injury behavior is prevalent among undergraduate students which warrants further concern.
