Association of adverse childhood experiences and non-suicidal self-injurious interactions with suicide-related behaviors in junior high school students
Objective To explore the association between adverse childhood experiences(ACEs)and non-suicidal self-injury(NSSI)and suicide-related behaviors among junior high school students,so as to provide a reference basis for the prevention of jun-ior high school students'suicide.Methods From May to June 2023,a total of 7 392 junior high school students in three districts and counties of Chongqing were selected for self-administered questionnaire survey by stratified cluster sampling and convenience sampling methods.The questionnaire survey was conducted using the Chinese version of the Childhood Trauma Scale,Adolescent NSSI Assessment Questionnaire,and Suicide Related Behavior Questionnaire.Statistical analysis was performed by using x2 test,multifactorial Logistic regression model,and additional interaction analysis was used to calculate the estimated relative excess risk due to interaction(RERI),attributable proportion(AP),and synergy index(S),as well as 95％CI.Results The detection rate of NSSI among junior high school students was 38.03％,the detection rate of ACEs was 41.76％,and the detection rates of suicidal ideation,suicide planning,and suicide attempt were 27.99％,9.90％,and 4.75％,respectively.ACEs and its dimensions,and NSSI were the influencing factors for suicide-related behaviors(OR=1.83-10.66,P＜0.01).The result of the additive interaction showed that ACEs and NSSI,PN and NSSI,EA and NSSI,EN and NSSI all had additive interactions on suicide-related behaviors(RERI=0.45-39.15,AP=0.10-1.09,S=1.02-3.92).And ACEs and its dimensions had additive interactions with NSSI on sui-cide-related behaviors,for junior high school students with both ACEs and NSSI had 11.45,20.38,and 28.76 times the risk of sui-cidal ideation,suicidal planning,and suicidal attempts as compared to junior high school students without ACEs and without NSSI(P＜0.05).Conclusions ACEs and NSSI among junior high school students have an additive interaction effect on suicide related behaviors.ACEs and NSSI should be reduced to prevent suicidal behavior among middle school students.
