Adverse childhood experiences and suicidal behaviors of senior high school students in Nanchang City

Objective To understand the incidence of suicidal ideation, suicidal planning and adverse childhood experiences in high school students, and to explore the relationship among adverse childhood experiences and suicidal ideation and suicidal planning, so as to master the cumulative effect of adverse childhood experiences on suicidal ideation and suicidal planning. Methods A stratified cluster random sampling method was adopted to select 5 schools from 34 high schools in Nanchang City according to the admission score of the middle school entrance examination from high to low. A total of 884 senior high school students were surveyed. Results Among the 884 senior high school students, 125(14.14%) had suicidal ideation, and 55(6.22%) had suicidal plan. Physical abuse(OR=3.002, P<0.001) and mental abnormality in family members(OR=3.465, P<0.001) were positively correlated with suicidal ideation. Sexual abuse(OR=3.105, P=0.008), physical abuse(OR=3.439, P<0.001) and mental abnormality of family members(OR=5.295, P<0.001) were positively correlated with suicide planning through Logistic analysis. With the increase of the number of adverse childhood experiences, the risk of suicidal ideation and suicide plan increased. People with three or more adverse childhood experiences had suicidal ideation OR=10.836 and suicide planning OR=22.660 through cumulative effect analysis. Conclusion Adverse childhood experience is an important risk factor for suicide ideation and suicide planning in senior high school students. Strengthening the intervention of adolescents with adverse childhood experiences can effectively prevent and control suicidal behaviors of senior high school students.
