Premenstrual dysphoric symptoms and lifetime suicide experiences in patients with mood disorder

Background
Premenstrual dysphoric symptoms (PMDS) commonly co-occurred with mood disorders and correlated with suicide experiences in women. This study aims to examine the associations between PMDS and lifetime suicide experiences in patients with mood disorders.
Methods
Participants were recruited from outpatient settings of two medical centers and one psychiatric hospital in Taiwan. Women aged 18–65 in non-acute state of major depressive disorder or bipolar affective disorder were recruited. PMDS and lifetime suicide experiences were defined by the Schedule for Affective Disorder and Schizophrenia-Lifetime. Lifetime suicide experiences were defined as no suicide experience, suicide plans only and suicide attempts.
Results
A total of 383 women participated in this study (54.8% of them were diagnosed with major depressive disorder), and 13.8% were diagnosed with PMDS. The prevalence of patients with lifetime suicide plans only and lifetime suicide attempts were 15.9% and 39.7%, respectively. In the univariate analysis, PMDS was correlated with lifetime suicide experience. After controlling for covariates, PMDS was a risk indicator for lifetime suicide attempts (OR: 3.46, 95% CI: 1.43–8.38) but not for suicide plans only (OR: 0.93, 95% CI: 0.28–3.11).
Conclusions
PMDS correlated with lifetime suicide experiences in women with non-acute mood disorders. In particular, PMDS exhibited as an independent correlate for lifetime suicide attempts.
