Hyperactivity-inattention symptoms in childhood and suicidal behaviors in adolescence: The Youth Gazel Cohort

Objective: Although a link has been suggested between attention deficit/hyperactivity disorder (ADHD) and completed suicide, little is known about the association with suicidal behaviors in community settings. This study addresses the relationship between childhood hyperactivity-inattention symptoms (HI-s) and subsequent suicidal behaviors. Method: Nine hundred sixteen subjects aged 7-18 were recruited from the general population and surveyed in 1991 and 1999. Parent and adolescent self-reports provided psychopathology and suicidal behavior pattern measures. Multivariate modeling was used to evaluate the effects of childhood HI-s and other risk factors on adolescent suicidal behaviors. Results: In males, HI-s independently accounted for the risk of lifetime suicide plans/attempts (OR=3.25, P = 0.02) and adolescent 12-month prevalence rates of suicide plans/attempts (OR=5.46, P = 0.03). In females, HI-s did not independently heighten the likelihood of suicidal behaviors. Conclusion: This survey suggests a possible specific link between HI-s and suicide plans/attempts in males.
