Koreans show the third highest suicide rate in the world, and many children and adolescents lost their parents during and after the Korean War. A total of 12,532 adults, randomly selected through a one-person- per-household method, completed the Korean version of the Composite Interna- tional Diagnostic Interview and questionnaire for suicidal ideation, plan, and attempt (response rate 80.2%). A total of 2,332 subjects experienced biological parental death in childhood (18.6%). Male suicide attempts were associated with age of exposure to maternal death from 0 to 4 years (adjusted OR = 4.48, 95% CI 1.3215.18) and from 5 to 9 years (adjusted OR = 5.52, 95% CI 1.9716.46), but not with paternal death, after adjusting for age, education years, marital status, monthly income, and psychiatric comorbidities. Female suicide attempts were associated with paternal death from 5 to 9 years (adjusted OR = 2.20, 95% CI 1.134.27), but not with maternal death. Childhood parental death is significantly associated with lifetime suicide attempt in the opposite-gender offspring, especially when exposure occurs before age 10.
