Özet
Background: Suicidal behavior in adolescents with major depressive disorder (MDD) remains a critical public health concern. While prior research has identified numerous correlates of suicide attempts, few longitudinal studies have distinguished between factors associated with incident versus recurrent suicidal behavior. Methods: In this prospective follow-up study, adolescents diagnosed with MDD were assessed at baseline (T0) and followed for one year (T1). Suicide attempts were evaluated longitudinally, and participants were categorized according to baseline and follow-up suicide attempt status. Multivariable logistic regression models were used to examine baseline correlates of suicide attempt history and prospective predictors of incident and recurrent suicide attempts. Results: At baseline, several social and environmental factors—including peer suicide attempts (OR = 14.07), parental consanguinity (OR = 6.32), witnessing domestic violence (OR = 3.57), labeling distress (OR = 1.36), and cybervictimization (OR = 1.07)—were associated with a history of suicide attempts. Longitudinal analyses revealed distinct risk profiles: witnessing domestic violence (OR = 30.00) and alcohol use (OR = 16.67) were most strongly associated with incident suicide attempts, whereas trauma-related factors such as physical neglect (OR = 1.24) and sleep disturbances such as insomnia (OR = 2.00) were more prominently associated with recurrent attempts. Parental consanguinity also emerged as a potentially relevant and underexplored risk marker. Conclusions: Incident and recurrent suicide attempts among adolescents with MDD may involve partly distinct clinical correlates and prospective risk patterns. These findings support stage-sensitive suicide prevention strategies and highlight parental consanguinity as a culturally relevant factor warranting further investigation.
