ABSTRACT
We sought to determine clinical predictors of postpartum depression (PPD), including the role of medication, in a sample of women followed prospectively during and after pregnancy. Women with a history of mood disorder were recruited and evaluated during each trimester and 1 week, 1 month, and 3 months postpartum. DSM-IV criteria for a major depressive episode were assessed by a psychiatric interview at each time point. Sixty-three women with major depression and 30 women with bipolar disorder entered the study and 75.4 % met DSM-IV criteria for a MDE during pregnancy, postpartum, or both. We modeled depression in a given time period (second trimester, third trimester, or 1 month postpartum) as a function of medication use during the preceding period (first, second, or third trimester). The odds of being depressed for those who did not use medication in the previous period was approximately 2.8 times that of those who used medication (OR 2.79, 95 % CI 1.38-5.66, p = 0.0048). Of 38 subjects who were psychiatrically well during the third trimester, 39.5 % (N = 15) met the criteria for a MDE by 4 weeks postpartum. In women who developed PPD, there was a high rate of a family history of PPD (53.3 %) compared to women who did not develop PPD (11.8 %, p = 0.02). While the use of psychiatric medications during pregnancy reduced the odds of being depressed overall, the use of psychiatric medications during pregnancy may not protect against PPD in women at high risk, particularly those with a family history of PPD.

BACKGROUND: We sought to determine the prevalence of, and association between, reproductive cycle-associated mood symptoms in women with affective disorders. We hypothesized that symptoms would correlate with each other across a woman's reproductive life span in both major depression (MDD) and bipolar I disorder (BP). METHODS: 2412 women with, MDD or BP were asked standardized questions about mood symptoms prior to menstruation, within a month of childbirth and during perimenopause. Lifetime rates for each of these symptom types were determined and an odds ratio was calculated correlating each of the types with the others. RESULTS: Of 2524 women with mood disorders, 67.7% reported premenstrual symptoms. Of those at risk, 20.9% reported postpartum symptoms and 26.4% reported perimenopausal symptoms. The rates did not differ between women with MDD and BP but were significantly different from women who were never ill. The symptoms were significantly correlated in women with MDD with odds ratios from 1.66 to 1.82, but were not in women with BP. LIMITATIONS: This is a secondary analysis of a sample that was collected for other purposes and is based upon retrospective reporting. CONCLUSIONS: Reproductive cycle-associated mood symptoms were commonly reported in women with mood disorders and did not differ based on diagnosis. In MDD, but not BP, the occurrence of these symptoms was trait-like as the presence of one predicted the occurrence of the others. Further prospective study is required to clarify the determinants of this trait.
