PurposeWe examined the prevalence, correlates, comorbidities, and suicidal tendencies of premenstrual dysphoric disorder (PMDD) according to the DSM-IV criteria in a nationwide sample of Korean women.MethodsA total of 2,499 women aged 18-64 years participated in this study. Diagnostic assessments were based on the Korean version of the Composite International Diagnostic Interview (CIDI) 2.1 and its 12-month PMDD diagnostic module, which were administered by lay interviewers. The frequencies of DSM-IV psychiatric disorders, insomnia, and suicidal tendency were analyzed among PMDD cases and compared with non-PMDD cases, and both odds ratios and significance levels were calculated.ResultsThe 12-month prevalence rate of DSM-IV-diagnosed PMDD was 2.4 %. Among subjects with PMDD, 59.3 % had at least one psychiatric illness; in comparison, the control frequency was 21.8 %. Associations between PMDD and alcohol abuse/dependence, major depressive disorder, post-traumatic stress disorder, social phobia, specific phobia, somatoform disorder, insomnia, and suicidality were overwhelmingly positive and significant (p < 0.05), after controlling for age. Physical illness and being underweight were associated with increased risks of PMDD (p < 0.05).ConclusionsPMDD was prevalent in the nationwide sample of Korean women and was frequently associated with other psychiatric disorders, insomnia, and suicidality, suggesting the need to detect and treat women who experience PMDD.
