Prospective study of postpartum depression in an Israeli cohort: prevalence, incidence and demographic risk factors

Postpartum depression: prevalence and determinants in Lebanon

This study assesses the prevalence and determinants of postpartum depression (PPD). 396 women delivering in Beirut and a rural area (Beka'a Valley) were interviewed 24 hours and 3-5 months after delivery. During the latter visit, they were screened using the Edinburgh postnatal depression scale. The overall prevalence of PPD was 21% but was significantly lower in Beirut than the Beka'a Valley (16% vs. 26%). Lack of social support and prenatal depression were significantly associated with PPD in both areas, whereas stressful life events, lifetime depression, vaginal delivery, little education, unemployment, and chronic health problems were significantly related to PPD in one of the areas. Prenatal depression and more than one chronic health problem increased significantly the risk of PPD. Caesarean section decreased the risk of PPD, particularly in Beirut but also in the Beka'a Valley. Caregivers should use pre- and postnatal assessments to identify and address women at risk of PPD.

The course of postpartum psychiatric disorders in women and their partners

This study examined the course of postpartum psychiatric disorders in a community sample of mothers and their partners to determine whether sociodemographic variables, life stress, and psychiatric history were related to persistence of mental health problems. At 6 months postpartum, 48 index couples where the wife had a psychiatric disorder at 2 months postpartum and 50 control couples with no such diagnosis underwent diagnostic interviews and completed questionnaires on psychological symptoms, life stress, and treatment history. The results indicate that at follow-up, 54% of the index mothers still had a psychiatric diagnosis, as did 60% of their partners who had had a psychiatric diagnosis at 2 months postpartum. Socioeconomic status, country of origin, and life stress were related to persistence, as were diagnosis and timing of onset of the disorder. About a third of the parents were referred for treatment. It is concluded that for many families, postpartum psychiatric disorders are not a transient phenomenon.

Predictors, prodromes and incidence of postpartum depression

The purpose of this study was to determine the incidence of clinically significant depression occurring between 1 and 4 months postpartum and to investigate whether somatic complaints, subsyndromal depressive symptoms, or birth-related concerns among non-depressed women at 1 month were predictive of postpartum depression. This is a prospective cohort study of 465 women from the Wisconsin Maternity Leave and Health Project (WMLHP). Women who were not depressed at 1 month postpartum were reassessed 3 months later for depression occurring at any time in the interval between 1 and 4 months postpartum. Depression was defined as either meeting the criteria for major depression on the National Institute of Mental Health (NIMH) Diagnostic interview Schedule (DIS) or scoring above 15 on the Center for Epidemiologic Studies Depression Scale (CES-D). Physical symptoms were assessed by an adapted Health Responses Scale. Other measures were developed specifically for the WMLHP. Of 465 women, 27 (5.8%) became clinically depressed between 1 and 4 months postpartum. In a logistic regression analysis, four variables (maternal age, depression during pregnancy, thoughts of death and dying at 1 month postpartum, and difficulty falling asleep at 1 month postpartum) were predictive of depression at 4 months postpartum. Breast-feeding, mode of delivery, family income, parity and mother's education did not predict depression. The existence of subsyndromal depressive symptoms, particularly thoughts of death and dying, may represent a prodromal phase of depression and should alert clinicians to the possibility of future postpartum depression. Women with a history of depression during pregnancy should be monitored for signs of postpartum depression for a minimum of 4 months. Obstetricians are in a unique position during the postpartum check-up to screen women for these predictors of future postpartum depression and possibly to avert the development of a clinically significant depressive episode.

An international study exploring levels of postpartum depressive symptomatology

OBJECTIVE

Differences in postpartum depressive symptomatology (PPDS) among an international sample of 892 women from nine countries representing five continents were explored.

METHOD

Edinburgh Postnatal Depression Scale (EPDS) and Beck Depression Inventory (BDI) were used to assess PPDS among a convenience sample that completed the two questionnaires twice, yielding a total of four sets of scores per subject. Women sampled were primiparae with no obstetrical complications, and had a healthy baby. Depression history and therapy were ruled out as exclusion criteria.

RESULTS

Mean scores for EPDS and BDI varied across sites at both time points (P value<.001). European and Australian women had the lowest levels of PPDS, USA women fell at the midpoint, and women from Asia and South America had the highest depressive symptom scores. The moderate concordance between the EPDS and BDI suggested that the measures have complementary uses for screening and assessment.

CONCLUSION

Utility of EPDS and BDI for yielding profiles of postpartum women's depressive symptomatology was demonstrated. Further research to validate depressive symptom measures with diverse international populations is indicated.

Postpartum depression in an Israeli cohort: demographic, psychosocial and medical risk factors

Demographic, psychosocial and medical risk factors for postpartum depression (PPD) were studied prospectively in a community cohort of 288 Israeli women. An Edinburgh Postnatal Depression Scale score of > or = 10 at 6 weeks postpartum was the criterion for PPD. Psychosocial risk factors were found to be the most potent. Lack of social support, marital disharmony, depressive symptoms during pregnancy, history of emotional problems and prolonged infant health problems were most predictive of PPD. The major role of psychosocial factors in PPD was similar to that found in other countries. The results were somewhat different for new Russian immigrants. These findings indicate that early identification of women at risk for PPD is feasible, and that consideration should be taken of subgroups that may be at heightened risk, or for whom risk factors play different roles.
