Abstract
Objective: To determine potential risk factors associated with repeat suicide attempts among adolescents.
Method: Retrospective medical record review of all patients aged 13–20 years who presented to the emergency department at an inner city tertiary hospital after attempted suicide between 1994 and 1996. Subjects were identified using the International Classification of Diseases (ICD-9) codes E950.0 to E959.9 for attempted suicide. Study variables included demographic parameters, chronic medical conditions/illnesses, psychiatric and substance abuse disorders, history of sexual abuse and previous and subsequent suicide attempts. Variables univariately associated with repetition at p < 0.25 were entered into a multiple regression analysis.
Results: Eighty seven per cent of patients presented with a drug overdose. Seventy-six per cent of all subjects attempted suicide in the context of a dispute or relationship break-up. At least one psychiatric disorder was present in 76% of subjects at the index attempt. The most frequently diagnosed disorders were depression (45.5%) and drug (34%) and alcohol abuse (27%). Variables predicting repetition within 12 months were drug (OR = 3.891, p = 0.02) and alcohol abuse (OR = 3.56, p = 0.05), non-affective psychotic disorders (OR = 3.81, p = 0.04), and chronic medical conditions/illness (OR = 3.29, p = 0.03). A history of sexual abuse was almost significant (OR = 3.03, p = 0.06).
Conclusions: Adolescents most likely to re-attempt suicide with 12 months present with either substance abuse, non-affective psychotic disorders, chronic medical conditions, or a history of sexual abuse. All adolescents with a possible suicide attempt should receive a comprehensive mental health and psychosocial assessment. Closer scrutiny of the role of chronic illnesses and sexual abuse in both future research and clinical management is urged. A broad based, multidisciplinary intervention approach is recommended.
