Abstract:
Objective:To explore the association between adverse childhood experiences (ACEs) and nonsuicidal selfinjury (NSSI) and suiciderelated behaviors among junior high school students, so as to provide a reference basis for the prevention of junior 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 χ 2 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 suiciderelated 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 suiciderelated 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 suiciderelated behaviors, for junior high school students with both ACEs and NSSI had 11.45, 20.38, and 28.76 times the risk of suicidal 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.
