Perinatal depressive disorder prevalence in Africa: A systematic review and Bayesian analysis

The epidemiology of maternal mental health in Africa: a systematic review

BACKGROUND

Despite a growing body of evidence on maternal mental health in Africa, significant gaps remain in understanding its overall landscape, risk factors/determinants, immediate and long-term effects, accessibility to healthcare and services, and availability of practicable/effective interventions. This paper provides a thorough review of both peer-reviewed and grey literature and makes key recommendations and directions for future research and development.

METHODS

We systematically reviewed extant evidence using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 guidelines. Peer-reviewed studies published in English between 2010, and June 2024 were included based on a priori criteria. The National Institutes of Health (NIH) and Critical Appraisal Skill Program (CASP) quality assessment tools were used to critically appraise the reliability, validity and overall quality of included articles. A qualitative narrative synthesis was perfomed to summarize the findings effectively.

RESULTS

A total of 206 full-text articles evaluated for eligibility and inclusion in the systematic review, predominantly observational studies with a minority employing randomized controlled trial (RCT) designs, were included, with 70%, 22%, and 8% of the articles rated as good, fair, and poor quality, respectively. Women in Africa experience a wide range of common perinatal mental disorders, including major depressive disorders and psychosis, either discretely or comorbid. Socioeconomic disadvantages and other intertwined poverty-related factors at the individual, family, social, and environmental levels are implicated in maternal mental health disorders. Currently, there is insufficient evidence regarding the short- and long-term health, development, and social impacts of maternal mental health. Addtionally, there is limited knowledge about the availability and accessibility of mental healthcare, evidence-based context-specific interventions, and healthcare-seeking behaviors of women in Africa, as well as their access to and utilization of mental health services.

CONCLUSION

The evidence base on maternal mental health in Africa suffers from considerable variability, inconsistency, and equivocal findings resulting from heterogeneity across the studies. This restricts generalizability and the ability to draw valid conclusions. Published studies also likely underestimate the scale and health impacts of perinatal mental disorders. Evidence from these studies are rarely used to inform policies and programs. The maternal mental health ecosystem in Africa needs to be better understood. More rigorous study designs should be implemented to focus on evidence generation and the evaluation of interventions, alongside robust integration of mental health services within health systems. Policy initiatives aimed at reducing socioeconomic disparities in maternal, newborn, and child health, particularly concerning maternal mental health, must be supported by these studies.

ARTICLE HIGHLIGHTS

• Women across Africa suffer from various mental health problems, including major depressive disorders, anxiety, and psychosis, occurring separately or in combination. • The evidence base on maternal mental health in Africa displays significant variability, inconsistency, and ambiguous findings, largely attributed to study heterogeneity. • Factors at the individual, familial, societal, and environmental levels contribute to poverty-related issues that can lead to or worsen maternal mental health disorders. • Current evidence has not been synthesized to improve our understanding of the short- and long-term health impacts, developmental consequences, and social implications of maternal mental health conditions, as well as the healthcare-seeking behaviors and access to mental health services. • Insufficient policy prioritization and funding for maternal mental health in Africa hinder the development, evaluation, and sustainability of interventions. • There is an urgent need to integrate mental health services into primary healthcare, particularly in resource-limited settings across Africa. This integration should be guided by evidence from rigorous research that uses longitudinal designs. It is also essential to emphasize the importance of investing in digital and community-based approaches to improve the accessibility to mental health services.

Determination of depression prevalence in pregnant women living with HIV aged 18 years and older: A meta-analysis study

BackgroundPregnant women living with HIV are known to be at higher risk of depression than pregnant women without HIV. Accompanied by a systematic literature review, the aim of this study was to determine the global prevalence of depression in pregnant women living with HIV.MethodsPubMed, Scopus, Google Scholar and Web of Science databases were searched. The references of the included publications and a similar meta-analysis study were also reviewed. The 19 included studies were assessed for quality using standard forms. Pooled prevalence was calculated using a random effects model. Heterogeneity and publication bias were assessed using various methods. Subgroup analyses and meta-regression were also performed.ResultsOf the 19 studies included in the review, six of the studies were published between 2008 and 2014, and 13 were published between 2017 and 2023. 15 studies were conducted in African countries. According to study type, eight studies were cross-sectional and seven were cohort studies. The pooled prevalence of depression was calculated to be 45%. The prevalence in African countries was 37.7%. The studies were found to be statistically significantly heterogeneous. Tests and funnel plots showed no publication bias in this meta-analysis. The variables place, study type and scale made the model significant in the meta-regression.ConclusionIn this meta-analysis, 6379 women aged 18 years and older were examined and their depression levels were found to be high. Taking steps to struggle with HIV and depression in people living with HIV seems important.

A global perspective: Access to mental health care for perinatal populations

Perinatal mental health care differs around the world. We provide a global perspective on the current status of service provision, barriers and facilitators to access, and strategies to improve access in high-income and low- and middle-income countries across five continents (Asia, Africa, Europe, North America and South America). Many of the countries considered do not have universal healthcare coverage. This poses a challenge to perinatal mental health care access. However, there are other social and structural barriers to access, including stigma and other sources of marginalization and discrimination. Yet there are opportunities discussed herein to learn more about what perinatal mental health services work for what populations* and in what circumstances, by adopting a global lens to examine innovative solutions utilized across geographical settings.

Possible depression in new tuberculosis patients in the Free State province, South Africa

Background

Despite compelling evidence of comorbidity between tuberculosis (TB) and depression, little is known about the prevalence and determinants of depression among TB patients in the Free State province in South Africa.

Objectives

This study assessed the prevalence and factors associated with possible depression among new drug susceptible TB patients attending primary health care facilities.

Method

The study followed a cross-sectional design. Trained fieldworkers conducted face-to-face interviews with conveniently selected patients. Depression was assessed using the Patient Health Questionnaire-9. Data were subjected to descriptive and binomial logistic regression analyses.

Results

Out of 208 patients, 46.2% screened positive for possible depression - 22.6%, 18.8%, and 4.8% presenting with mild, moderate, and severe symptoms, respectively. Possible depression odds were three times higher among females than males (adjusted odds ratio [AOR]: 3.0; 95% confidence interval [CI]: 1.25-7.32) and 2.7 times higher among extrapulmonary TB (EPTB) than pulmonary TB patients (95% CI: 1.03-7.21). Longer TB treatment duration was protective (AOR: 0.8; 95% CI: 0.70-0.95) against depression. Among human immunodeficiency virus-positive patients, those on antiretroviral therapy (ART) had 2.5 times higher odds of depression (95% CI: 1.13-5.46) than those who were not.

Conclusion

The results highlight a significant burden of possible depression among new TB patients, particularly among females, EPTB patients, and ART recipients. Longer TB treatment duration may offer some protection against depression symptoms, suggesting a need for enhanced adherence support.

Contribution

The results suggest that strengthening TB and mental health service integration is critical to improving treatment outcomes, overall well-being of TB patients, and the performance of the Free State TB programme.

Effects of mindfulness-based interventions (MBIs) on depression in pregnant women: A systematic review and meta-analysis

OBJECTIVE

We synthesized the effects of mindfulness-based interventions (MBIs) on depression in pregnant women.

METHOD

Ten electronic databases were searched from inception to September 2022. We reviewed studies on outcomes for pregnant women with depression receiving mindfulness-based interventions. We only reviewed studies written in English. A random-effects model was used to compute the effect size. Funnel plot, Q statistics, and I2 were used to test the heterogeneity across studies. We examined moderators to explore sources of heterogeneity.

RESULTS

Across 19 included studies (N = 1480), 717 pregnant women participated in mindfulness interventions; 763 served as controls. Mean age ranged from 25.3 to 33.6 years. Overall, mindfulness-based interventions showed reduced depression compared to control groups (g = 0.457, 95%CI 0.254, 0.659, I2 = 68 %). With subgroup analysis, mindfulness-based cognitive therapy had a greater effect on reducing depressive symptoms (g = 1.13) than mindfulness-based stress reduction (g = 0.64) and adapted mindfulness-based interventions (g = 0.31). No quality indicators moderated the ES of mindfulness-based interventions on depression.

CONCLUSION

Mindfulness-based interventions significantly improved depression among pregnant women, especially mindfulness-based cognitive therapy (MBCT). Clinicians and health providers should consider using MBIs as alternative complementary treatment for improving and preventing depression in pregnant women.

Global prevalence of perinatal depression and anxiety during the COVID-19 pandemic: An umbrella review and meta-analytic synthesis

INTRODUCTION

The prevalence of depression and anxiety symptoms in pregnant and postpartum women during the COVID-19 pandemic was assessed by several systematic reviews (SRs) and meta-analyses which provided contrasting and different results. We aimed to summarize the evidence relating to the global prevalence of anxiety and depression among pregnant and postpartum women during the COVID-19 pandemic.

MATERIAL AND METHODS

An umbrella review of SRs and meta-analyses was performed. Searches were conducted in electronic databases up to April 2023. SRs and meta-analyses reporting the prevalence of perinatal anxiety and depression during the COVID-19 pandemic were selected for eligibility. Primary studies extracted from eligible meta-analyses were included in the quantitative synthesis. The research protocol was registered on PROSPERO (CRD42020173125).

RESULTS

A total of 25 SRs (198 primary studies) and 12 meta-analyses (129 primary studies) were included in the qualitative and quantitative synthesis, respectively. Studies involved data from five continents and 45 countries. The pooled prevalence of antenatal and postpartum depression was 29% (n = 55; 95% CI: 25%-33%) and 26% (n = 54; 95% CI: 23%-30%), respectively. In the case of anxiety, the pooled antenatal and postnatal prevalence was 31% (n = 44; 95% CI: 26%-37%; n = 16; 95% CI: 24%-39%). Differences emerged between continents, with Africa having the highest prevalence of perinatal depression and Oceania and Europe having the highest prevalence of antenatal and postnatal anxiety. The prevalence also varied depending on the assessment tools, especially for antenatal anxiety. A medium-high quality of the studies was observed. One SR assessed strength-of-evidence, reporting very low strength.

CONCLUSIONS

During the COVID-19 pandemic, depression and anxiety were common, affecting almost one in three perinatal women globally. A high heterogeneity and a risk of publication bias were found, partially due to the variety of assessment tools and cut-offs. The results may not be generalized to minorities. Studies on the prevalence of clinical diagnoses are needed. Based on our results it is not possible to firmly affirm that the COVID-19 pandemic was the main factor that directly increased perinatal depression and anxiety during the past few years. Future studies should study other factors' impact.

An Intervention to Improve Mental Health and HIV Care Engagement Among Perinatal Women in Malawi: A Pilot Randomized Controlled Trial

Perinatal depression (PND) is common and an important barrier to engagement in HIV care for women living with HIV (WLHIV). Accordingly, we adapted and enhanced The Friendship Bench, an evidence-based counseling intervention, for perinatal WLHIV. In a pilot randomized trial (NCT04143009), we evaluated the feasibility, acceptability, fidelity, and preliminary efficacy of the Enhanced Friendship Bench (EFB) intervention to improve PND and engagement in HIV care outcomes. Eighty pregnant WLHIV who screened positive for PND symptoms on the Self-Report Questionnaire (≥ 8) were enrolled, randomized 1:1 to EFB or usual care, and followed through 6 months postpartum. Overall, 100% of intervention participants were satisfied with the intervention and 93% found it beneficial to their overall health. Of 82 counseling sessions assessed for fidelity, 83% met or exceeded the fidelity threshold. At 6 months postpartum, intervention participants had improved depression remission (59% versus 36%, RD 23%, 95% CI 2%, 45%), retention in HIV care (82% versus 69%, RD 13%, -6%, 32%), and viral suppression (96% versus 90%, RD 7%, -7%, 20%) compared to usual care. Adverse events did not differ by arm. These results suggest that EFB intervention should be evaluated in a fully powered randomized trial to evaluate its efficacy to improve PND and engagement in HIV care outcomes for WLHIV.

Prevalence of Postpartum Depression Based on Diagnostic Interviews: A Systematic Review and Meta-Analysis

Background

Postpartum depression (PPD) is common after childbirth. Previous reviews on the prevalence of PPD have mainly included results that relied on screening instruments or a mixture of such instruments and diagnostic interviews. In this study, we aimed to assess the prevalence of PPD based exclusively on studies using diagnostic interviews, as they provide the most reliable and valid approach for defining "caseness."

Methods

Using PubMed, Web of Science, Cochrane Library, Embase, CNKI, WANFANG DATA, and CBM up to September 18, 2022, we searched for original articles reporting data that could be used to calculate the prevalence of PPD based on diagnostic interviews. A random-effect meta-analysis model was then used to estimate the pooled prevalence. In addition, we assessed quality, heterogeneity, and publication bias across studies. Also, we did subgroup analyses to explore the pooled prevalence at different time points and settings. This study was registered with PROSPERO, CRD42021244539.

Results

Of 17,115 articles retrieved, 54 studies were included (total sample size = 15,586 women). The pooled prevalence of all depression and major depression within one year postpartum was 12.1% (95% CI 10.3%-14.1%; I 2 = 91.0%) and 7.0% (95% CI 5.7%-8.4%; I 2 = 83.0%), respectively. The peaks of all depression occurred during the first 6 months postpartum, especially 2-3 weeks and 6-8 weeks. Subgroup analyses showed that the prevalence of major depression was associated with the income level of countries (higher in low- and middle-income countries (LMICs) than in high-income countries (HICs)) and diagnostic criteria (higher using ICD than using DSM and RDC). No evidence of publication bias was found.

Conclusions

Approximately one in eight postpartum women experiences a depressive condition, with one in fifteen suffering major depression. The pooled prevalence based on diagnostic interviews was lower than the existing consensus, which was largely based on self-reported screening instruments. The higher prevalence in LMICs underlines the importance of strengthening research and service provision among these populations.

Perceptions and experiences of prenatal mental health: A qualitative study among pregnant women in Ghana

Prenatal mental health problems can have adverse effects on the health and wellbeing of the mother as well as her baby. However, the factors associated with its etiology, expression, and coping mechanisms in Ghana remain understudied. This qualitative study explored the perceptions and experiences of prenatal mental health problems among 21 pregnant women in Accra through semi-structured interviews. Interpretative Phenomenological Analysis led to three dominant themes; "conceptions of prenatal mental disorders" (sub-themes: awareness and constructions of prenatal mental health problems), "experiences of mental health problems" (sub-themes: symptoms of prenatal mental health problems and causal attributions of prenatal mental health problems) and "coping mechanisms of the pregnancy experience" (subthemes: faith, social support and work). The lack of knowledge of mental health disorders in this study and the expression of contextually relevant and culturally defined constructions and experiences of prenatal mental health problems, highlight the need for the development of culturally suitable interventions within the Ghanaian context.

Effects of the Covid-19 Pandemic on the Prevalence of Insomnia, Anxiety, and Depression During Pregnancy: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis study aims to determine the effects of the Covid-19 pandemic on the prevalence of insomnia, anxiety, and depression symptoms during pregnancy. Reviews were done through PubMed, EBSCO (Medline, CINAHL), Embase (OVID), Web of Science, PsycINFO, TR Index, Turkish Thesis Center databases using (pregnancy OR pregnant) and (sleep OR sleep disorders OR insomnia), and (anxiety OR depression) keywords between April and May 2021. The meta-analysis included 48 articles (sample: 77,299). It was found that the Covid-19 pandemic did not affect the prevalence of depression symptoms and anxiety during pregnancy, but it increased insomnia. While insomnia ratio was reported 39.6% (95% CI: 0.253-0.560) in the studies conducted before the pandemic, it was reported 88.8% (95% CI: 0.821-0.921) in the studies conducted during the pandemic. This study found that the Covid-19 pandemic did not have effects on depression symptoms and anxiety, but it increased insomnia complaints.

Maternal Depression and Associated Factors Among Pregnant Women Attending Ante Natal Care, Southern Ethiopia: Cross-Sectional Study

Background

Patients with depressed mental disorders may experience a lack of interest or pleasure, a poor mood, feelings of guilt or unworthiness, sleep and appetite disturbances, and easy fatigability. Based on the degree of the condition, depression is classed as mild, moderate, or severe. Maternal depression is the most common psychiatric condition during pregnancy, and its harmful effects have serious ramifications for both the mother and the fetus. Almost one in every four women will experience depression at some point in her life, the majority of which will occur during her childbearing years. Studies reports showed that antenatal depression is a common maternal problem in Ethiopia and as reported antenatal depression ranges in Ethiopia from 19.04 to 29.92%.

Objective

To assess the prevalence of maternal depression and associated factors among antenatal care attendants at Wolayta Sodo Teaching and Referral hospital, Southern Ethiopia.

Methods

Health facility based cross-sectional study was conducted at Wolayta Sodo Teaching and Referral Hospital from May 01 to 30, 2018. Data were collected from through face to face interview at exit from antenatal care unit using structured questionnaire and checklist adopted from patient Health Questionnaire (PHQ-9). Data were collected from 309 antenatal attendant mothers using systematic random sampling from each either mother. Binary and multivariable logistic regression model was employed to identify factors associated with maternal depression at P-value <0.05 level of significant.

Result

Depression among pregnant mother was found to be 27.2% (95% Cl: 22, 32%). Women's level of education; being elementary school (AOR = 6.35 95%CL (2.32, 17.38), completing high school and above (AOR = 3.35, 95%CL 1.33, 8.47) were associated with maternal depression whereas having good husband support was protective for maternal depression (AOR = 0.4, 95%CL: 0.19, 0.83) and also not using substance during pregnancy period was protective for maternal depression (AOR = 0.39, 95%CI, 0.19, 0.77).

Conclusion

The frequency of mother depression in this community was greater than in previous Ethiopian studies reported. Maternal depression was linked to a woman's level of education, husband support, and substance usage. This suggested that health care providers regarding pregnant women should emphasize the importance of husband support, substance usage and women level of education.

Burden of severe maternal peripartum mental disorders in low- and middle-income countries: a systematic review

Peripartum severe mental disorders (PSMDs) encompass schizophrenia, affective psychosis, and psychotic and non-psychotic forms of bipolar disorders. PSMDs are well documented in high-income countries. However, much less is known about the prevalence of PSMDs in low- and middle-income countries (LMICs). The aim was to review the available literature systematically and estimate the prevalence of PSMDs among women in LMICs. We searched the Ovid MEDLINE, Embase, PsycINFO, CINAHL and Maternity and Infant Care databases systematically from the date of inception to Dec 31, 2020, for English-language publications with data on the prevalence of PSMDs among women in World Bank-defined LMICs. Selection of studies, extraction of data and assessment of study quality were each undertaken independently by at least two of the investigators. A total of five studies (completed in three countries spanning two continents) met the inclusion criteria. Five studies reported cumulative incidence of postpartum psychosis (ranging from 1.1 to 16.7 per 1000 births). We found no studies on the prevalence of severe mental disorder during pregnancy in these settings. Marked heterogeneity in methodology precluded meta-analysis. These findings indicate that PSMDs occur at a similar prevalence in low- and middle-income to high-income countries. However overall, there is a paucity of high-quality evidence from these settings. There is a need for rigorous studies with standardized methods to increase knowledge of the nature, prevalence, and determinants of PSMDs among women in resource-constrained LMICs to inform policies, service development, program planning and health professional training.
