- OBJECTIVES: To assess suicide risk in men with mood disorders at the postpartum period. METHODS: We conduct a longitudinal study with 650 men whose child has born from April 2007 to May 2008 at maternity hospital. The first assessment was in the antenatal period and the second within 30 to 60days postpartum. Suicide risk, anxiety disorders, hypomanic, manic and mixed episodes were assessed by the Mini International Neuropsychiatric Interview (MINI). RESULTS: The prevalence of suicide risk in fathers in postpartum was of 4.8%. Fathers with postpartum depression were 20.97 (CI: 5.74; 76.53) more likely to present suicide risk and those with mixed episodes showed a chance of 46.50 (CI: 10.52; 205.53) times higher than those who did not suffer from any mood disorder. CONCLUSION: Mixed episodes are common in fathers at postpartum, posing a higher suicide risk than depressive and manic/hypomanic episodes. Therefore, in order to reduce the suicide risk, clinicians should address and treat adequately mixed affective states in this specific population.
