Abstract

BACKGROUND: To determine the prevalence of suicide behaviors and the associations between aggression and suicide behaviors among a nationwide school-based sample of adolescents in rural China.
METHODS: A total of 16,271 students from 24 junior and 23 senior high schools in five provinces of China participated in a self-administered anonymous survey to report suicide ideation, plans, attempts, aggression and other related information. Multivariable logistic regression models were used to investigate the associations between aggression and the risks of suicide behaviors while controlling for potential confounders.
RESULTS: The prevalence of suicide ideation, plans, and attempts during the past one year was 15.1%, 7.2%, and 3.5% respectively. In the fully adjusted model, participants with high level of total aggression had 4.31 times (95% CI, 3.69-5.05), 4.10 times (95% CI, 3.26-5.11), and 3.29 times (95% CI, 2.62-4.93), higher risk of suicide ideation, plans, and attempts, respectively, compared with subjects who had low level of total aggression. Moreover, high levels of all the five dimensions of total aggression also had positive associations with suicide behaviors. LIMITATIONS: This study was cross-sectional. Hence, the causal link between aggression and suicide behaviors should be verified in the future studies.
CONCLUSIONS: This study suggests that aggression may be a risk factor for suicide behaviors among rural Chinese adolescents. Our findings highlight the importance of aggression treatment in suicide prevention programs. Further longitudinal studies are needed to confirm these associations.
