Cross-Cultural Approach of Postpartum Depression: Manifestation, Practices Applied, Risk Factors and Therapeutic Interventions

Economic and Health Predictors of National Postpartum Depression Prevalence: A Systematic Review, Meta-analysis, and Meta-Regression of 291 Studies from 56 Countries

BACKGROUND

Postpartum depression (PPD) poses a major global public health challenge. PPD is the most common complication associated with childbirth and exerts harmful effects on children. Although hundreds of PPD studies have been published, we lack accurate global or national PPD prevalence estimates and have no clear account of why PPD appears to vary so dramatically between nations. Accordingly, we conducted a meta-analysis to estimate the global and national prevalence of PPD and a meta-regression to identify economic, health, social, or policy factors associated with national PPD prevalence.

METHODS

We conducted a systematic review of all papers reporting PPD prevalence using the Edinburgh Postnatal Depression Scale. PPD prevalence and methods were extracted from each study. Random effects meta-analysis was used to estimate global and national PPD prevalence. To test for country level predictors, we drew on data from UNICEF, WHO, and the World Bank. Random effects meta-regression was used to test national predictors of PPD prevalence.

FINDINGS

291 studies of 296284 women from 56 countries were identified. The global pooled prevalence of PPD was 17.7% (95% confidence interval: 16.6-18.8%), with significant heterogeneity across nations (Q = 16,823, p = 0.000, I2 = 98%), ranging from 3% (2-5%) in Singapore to 38% (35-41%) in Chile. Nations with significantly higher rates of income inequality (R2 = 41%), maternal mortality (R2 = 19%), infant mortality (R2 = 16%), or women of childbearing age working ≥40 h a week (R2 = 31%) have higher rates of PPD. Together, these factors explain 73% of the national variation in PPD prevalence.

INTERPRETATION

The global prevalence of PPD is greater than previously thought and varies dramatically by nation. Disparities in wealth inequality and maternal-child-health factors explain much of the national variation in PPD prevalence.

Sociodemographic and Obstetric Factors Related to Symptoms of Postpartum Depression in Hispanic Women in Rural California

OBJECTIVE

To investigate the relationships among sociodemographic and obstetric factors and symptoms of postpartum depression (PPD) in Hispanic women living in rural California.

DESIGN

Quantitative, cross-sectional, descriptive design.

SETTING

Rural southern California communities.

PARTICIPANTS

A convenience sample of 223 Hispanic women, ages 18 to 42 years old, with one living infant younger than 12 months old.

METHODS

Interviewer-administered Edinburgh Postnatal Depression Scale and sociodemographic and obstetric history survey (maternal age, marital status, education, annual household income, employment, sex of infant, birth type, and number of children). Chi-square and logistic regression analyses were used to determine associations and predictive relationships among sociodemographic and obstetric factors and symptoms of PPD.

RESULTS

Low education levels, unemployment, cesarean birth, and more than one young child were significantly related to PPD risk (Edinburgh Postnatal Depression Scale scores ≥ 10). Many of the factors associated with PPD symptoms in this sample of Hispanic women were similar to those previously reported in the literature.

CONCLUSION

Our findings highlighted the need for PPD care among Hispanic women in rural areas. Early assessment and intervention for symptoms of PPD are needed to enhance health equity and promote better health for women who live in rural communities.

Migrant women's experiences, meanings and ways of dealing with postnatal depression: A meta-ethnographic study

Aim

To conduct a meta-ethnographic study of the experiences, meanings and ways of ‘dealing with’ symptoms or a diagnosis of postnatal depression amongst migrant women living in high income countries.

Background

Prevalence of postnatal depression is highest amongst women who are migrants. Yet many women do not seek help for their symptoms and health services do not always respond appropriately to migrant women’s needs. Studies have reported migrant women’s experiences of postnatal depression and it is timely to synthesise findings from these studies to understand how services can be improved.

Design

A meta-ethnographic synthesis of 12 studies reported in 15 papers

Data sources

Five databases were searched for papers published between January 1999 and February 2016

Review methods

The quality of included studies was assessed using the Critical Appraisal Skills Program tool. The synthesis process was guided by the seven steps of meta-ethnography outlined by Noblit and Hare.

Findings

Four key metaphors were identified: “I am alone, worried and angry—this is not me!”; ‘Making sense of my feelings’ ‘Dealing with my feelings’ and ‘What I need to change the way I feel!’. Primarily women related their feelings to their position as a migrant and as women, often living in poor socio-economic circumstances and they were exhausted keeping up with expected commitments. Many women were resourceful, drawing on their personal strengths and family / community resources. All the studies reported that women experienced difficulties in accessing appropriate services.

Conclusion

The meta-ethnographic study demonstrates the impact of migration on perinatal mental health, particularly for women lacking family support, who have no employment, a precarious migration status and/or relationship conflict. Migrant women are resourceful and this requires support through appropriate services. Further research is needed to evaluate effective support strategies for migrant women in the perinatal period.

Dietary n-3 Polyunsaturated Fatty Acids in Late Pregnancy and Postpartum Depressive Symptom among Japanese Women

BACKGROUND

The use of n-3 polyunsaturated fatty acids (n-3PUFA) in preventive or therapeutic modalities for postpartum depression, especially long-chain types such as eicosapentaenoic acid (EPA) and a docosahexaenoic acid (DHA), is of considerable interest. High n-3PUFA consumption has been reported among pregnant Japanese women. Therefore, analysis of this group could provide important insights into the relationship between postpartum depression and dietary n-3PUFA consumption. To further examine the relationship between the risk of postpartum depression and n-3PUFA consumption, we conducted a prospective hospital-based birth cohort study in Japan.

DESIGN AND METHODS

Our prospective birth cohort study was performed at the National Center for Child Health and Development (NCCHD) in suburban Tokyo, Japan. Dietary n-3PUFA intake during late pregnancy was assessed by a semi-quantitative food questionnaire and participants were categorized by quintile distributions of n-3PUFA intake. A Japanese translation of the Edinburgh Postnatal Depression Scale was used to screen women for postpartum depression at 1 month after delivery (967 women) and at 6 months after delivery (710 women). We performed logistic regression analysis to examine the relationship between the risk of postpartum depression and n-3PUFA consumption after adjusting for confounding factors.

RESULTS

Significant associations between EPA, DHA, and n-3PUFA intakes in late pregnancy and postpartum depression at both 1 and 6 months after delivery were not observed.

CONCLUSION

This prospective study indicated that EPA, DHA, and n-3PUFA intake during late pregnancy was not associated with the risk of postpartum depression.
