Perinatal suicidality: prevalence and correlates in a South African birth cohort

Suicide Ideation within and outside the Perinatal Period: An Exploration of Interpersonal Factors from a Maternal Cohort in Rural Pakistan to Improve Intervention Targeting

OBJECTIVE

Suicide accounts for substantial mortality in low-resourced settings and contributes to nearly 20% of maternal deaths. In Asia, interpersonal conflict is a salient factor that contributes to suicidal thoughts and actions, yet limited research has been done to explore the type and timing of such conflicts and a woman's accompanying social support. Identifying such risk factors can inform improved efforts to identify who to target for psychosocial interventions.

METHODS

Using the Bachpan Cohort study of mothers in Pakistan (n = 1154), we examined the prevalence and interpersonal influences on SI within the past two weeks of pregnancy and then at 3, 6, and 24 months after birth. Using hierarchical mixed effects models, we explored the separate and combined associations of interpersonal factors [e.g., social support, interpersonal conflict, isolation, and past year intimate partner violence (IPV)] on SI at each timepoint.

RESULTS

SI prevalence was highest in pregnancy (12.2%) and dropped to 5% throughout two years postpartum. The interpersonal conflict was independently associated with increased odds of SI in pregnancy and 24 months postpartum. IPV was associated with increased SI in pregnancy and 24 months postpartum. Isolation was not associated with SI at any timepoint. Perceived social support remained a robust independent factor associated with reduced SI at all timepoints.

CONCLUSION

In addition to screening and deploying interventions for perinatal women with depression, targeting interventions for those who also experience interpersonal conflict, including intimate partner violence, may significantly reduce suicidal thoughts and related sequelae. Social support is a viable and potentially powerful target to reduce the burden of suicide among women.HIGHLIGHTSSuicidal ideation prevalence was higher in pregnancy compared to postpartum.Perceived social support was independently associated with reduced suicidal ideation.Interventions addressing suicide must attend to women's family and social context.

Prevalence of Perinatal Anxiety and Related Disorders in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis

Importance

Anxiety disorders are associated with poor maternal and neonatal outcomes. Women in low- and middle-income countries (LMICs) are thought to be disproportionally burdened by these disorders, yet their prevalence is unclear.

Objective

To conduct a systematic review and meta-analysis to determine the prevalence of 6 anxiety and related disorders among perinatal women in LMICs.

Data Sources

Embase, MEDLINE, PsycINFO, Cochrane Library, CINAHL, and Web of Science databases were searched from inception until September 7, 2023.

Study Selection

Studies conducted in World Bank-defined LMICs and reporting prevalence of generalized anxiety disorder, obsessive-compulsive disorder, social anxiety disorder, posttraumatic stress disorder, panic disorder, or adjustment disorder during the perinatal period (conception to 12 months post partum) using a validated method were included.

Data Extraction and Synthesis

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. Study eligibility, extracted data, and risk of bias of included studies were assessed by 2 independent reviewers. Random-effects meta-analysis was used to estimate pooled point prevalence. Subgroup analyses were performed by specific anxiety disorder.

Main Outcomes and Measures

Main outcomes were prevalence estimates of each anxiety disorder, measured as percentage point estimates and corresponding 95% CIs.

Results

At total of 10 617 studies were identified, 203 of which met the inclusion criteria and reported the outcomes of 212 318 women from 33 LMICs. Generalized anxiety disorder was the most reported (184 studies [90.6%]) and most prevalent disorder at 22.2% (95% CI, 19.4%-25.0%; n = 173 553). Posttraumatic stress disorder was the second most prevalent (8.3%; 95% CI, 5.0%-12.2%; 33 studies; n = 22 452). Adjustment disorder was least prevalent (2.9%; 95% CI, 0.0%-14.1%; 2 studies; n = 475). The prevalence of generalized anxiety varied by country income status, with the highest prevalence among lower-middle-income countries (27.6%; 95% CI, 21.6%-33.9%; 59 studies; n = 25 109), followed by low-income (24.0%; 95% CI, 15.3%-33.8%; 11 studies; n = 4961) and upper-middle-income (19.1%; 95% CI, 16.0%-22.4%; 110 studies; n = 138 496) countries.

Conclusions and Relevance

These findings suggest that 1 in 5 women living in LMICs experience anxiety disorders during pregnancy and post partum. Targeted action is needed to reduce this high burden.

Measures of suicidality in perinatal women: A systematic review

BACKGROUND

Suicide is a leading cause of death for perinatal women. Identifying women at risk of suicide is critical. Research on the validity and/or reliability of measures assessing suicidality in perinatal women is limited. This review sought to: (1) identify; and (2) evaluate the psychometric properties of suicidality measures validated in perinatal populations.

METHODS

Nine electronic databases were systematically searched from inception to January 2022. Additional articles were identified through citation tracking. Study quality was assessed using an adapted tool, and the psychometric properties of measures were reviewed and presented using a narrative synthesis.

RESULTS

A total of 208 studies were included. Thirty-five studies reported psychometric data on ten suicidality measures. Fifteen studies reported both validity and reliability data, 12 reported more than one type of validity, seven validated more than one measure and four only reported reliability. Nearly all measures primarily screened for depression, with an item or subscale assessing suicidal ideation and/or behaviours. Three measures were specifically developed for perinatal women, but only two were validated in more than one study. The Postpartum Depression Screening Scale (PDSS), suicidal thoughts subscale, was validated most frequently.

LIMITATIONS

Methodological differences and variability between the measures (e.g., suicidality construct assessed, number of items and administration) precluded direct comparisons.

CONCLUSION

Further validation of suicidality measures is needed in perinatal women. Screening for perinatal suicidality often occurs in the context of depression. The development of a standalone measure specifically assessing suicidality in perinatal women may be warranted, particularly for use in maternity care settings.

Application of machine learning in predicting the risk of postpartum depression: A systematic review

BACKGROUND

Postpartum depression (PPD) presents a serious health problem among women and their families. Machine learning (ML) is a rapidly advancing field with increasing utility in predicting PPD risk. We aimed to synthesize and evaluate the quality of studies on application of ML techniques in predicting PPD risk.

METHODS

We conducted a systematic search of eight databases, identifying English and Chinese studies on ML techniques for predicting PPD risk and ML techniques with performance metrics. Quality of the studies involved was evaluated using the Prediction Model Risk of Bias Assessment Tool.

RESULTS

Seventeen studies involving 62 prediction models were included. Supervised learning was the main ML technique employed and the common ML models were support vector machine, random forest and logistic regression. Five studies (30 %) reported both internal and external validation. Two studies involved model translation, but none were tested clinically. All studies showed a high risk of bias, and more than half showed high application risk.

LIMITATIONS

Including Chinese articles slightly reduced the reproducibility of the review. Model performance was not quantitatively analyzed owing to inconsistent metrics and the absence of methods for correlation meta-analysis.

CONCLUSIONS

Researchers have paid more attention to model development than to validation, and few have focused on improvement and innovation. Models for predicting PPD risk continue to emerge. However, few have achieved the acceptable quality standards. Therefore, ML techniques for successfully predicting PPD risk are yet to be deployed in clinical environments.

The relationship between adverse childhood experiences and common mental disorders among pregnant women living with HIV in Malawi

INTRODUCTION

Adverse childhood experiences (ACEs) have been linked to common mental disorders (CMDs) such as anxiety and depressive thoughts. We examined the prevalence of ACEs and their association with CMDs among pregnant women living with HIV (PWLHIV) in Malawi-an HIV endemic resource-limited setting.

METHODS

This is a cross-sectional study of 798 PWLHIV enrolled in the VITAL Start trial in Malawi (10/2018 to 06/2021) (NCT03654898). ACE histories were assessed using WHO's Adverse Childhood Experiences International Questionnaire (ACE-IQ) tool. Depressive symptoms (somatic complaints, reduced vital energy, anxiety, and depressive thoughts) were assessed using WHO's Self Reporting Questionnaire 20-Item (SRQ-20) tool. Log-binomial regressions were used to examine the association between cumulative ACEs and each depressive symptom, as well as identify ACEs driving this association.

RESULTS

The mean age of our sample was 27.5 years. Over 95 % reported having experienced ≥1 ACE. On average, each participant reported four ACEs; 11 % reported sexual abuse. About 52 % and 44 % reported anxiety and depressive thoughts, respectively. In regressions, cumulative ACE scores were significantly associated with depressive symptoms-even after adjusting for multiple testing. This association was primarily driven by reports of sexual abuse.

LIMITATIONS

Data on maternal ACEs were self-reported and could suffer from measurement error because of recall bias.

CONCLUSIONS

ACEs are widespread and have a graded relationship with depressive symptoms in motherhood. Sexual abuse was found to be a primary driver of this association. Earlier recognition of ACEs and provision of trauma-informed interventions to improve care in PWLHIV may reduce negative mental health sequelae.

Maternal Suicide Ideation and Behaviour During Pregnancy and the First Postpartum Year: A Systematic Review of Psychological and Psychosocial Risk Factors

Suicide is a leading cause of maternal death during pregnancy and up to a year after birth (perinatal period). Many psychological and psychosocial risk factors for maternal suicidal ideation and behaviour have been investigated. Despite this, there have been no attempts to systematically search the literature on these risk factors. Additionally, few studies have described how the risk factors for suicidal ideation, attempted suicides and suicide deaths differ, which is essential for the development of tools to detect and target suicidal ideation and behaviour. Seven databases were searched up to June 2021 for studies that investigated the association between suicidal ideation and/or suicidal behaviour and psychological/psychosocial risk factors in pregnant and postpartum women. The search identified 17,338 records, of which 59 were included. These 59 studies sampled a total of 49,929 participants and investigated 32 different risk factors. Associations between abuse, experienced recently or during childhood, and maternal suicide ideation, attempted suicide and death were consistently reported. Social support was found to be less associated with suicide ideation but more so with suicide attempts. Identifying women who have experienced domestic violence or childhood abuse and ensuring all women have adequate emotional and practical support during the perinatal period may help to reduce the likelihood of suicidal behaviour.

Suicide and Maternal Mortality

PURPOSE OF REVIEW

Suicide is a leading cause of death in the perinatal period (pregnancy and 1 year postpartum). We review recent findings on prevalence, risk factors, outcomes, and prevention and intervention for suicide during pregnancy and the first year postpartum.

RECENT FINDINGS

Standardization of definitions and ascertainment of maternal deaths have improved identification of perinatal deaths by suicide and risk factors for perinatal suicide. Reports of a protective effect of pregnancy and postpartum on suicide risk may be inflated. Clinicians must be vigilant for risk of suicide among their perinatal patients, especially those with mental health diagnoses or prior suicide attempts. Pregnancy and the year postpartum are a time of increased access to healthcare for many, offering many opportunities to identify and intervene for suicide risk. Universal screening for suicide as part of assessment of depression and anxiety along with improved access to mental health treatments can reduce risk of perinatal suicide.

Suicidal ideation and behavior among perinatal women and their association with sleep disturbances, medical conditions, and known risk factors

OBJECTIVE

Suicide is considered one of the leading causes of maternal mortality, especially among women with postpartum depression. In the current systematic review, we conducted a qualitative data synthesis of recent studies exploring novel risk factors including sleep disturbances and medical conditions, alongside known and significant risk factors for perinatal suicidality.

EVIDENCE ACQUISITION

We conducted a systematic search of the literature according to PRISMA guidelines on PubMed, PsycNET, and Scopus databases. Search terms were "pregnancy" "OR" "postpartum" "OR" "peripartum" "OR" "perinatal" "OR" "postnatal" combined with the Boolean "AND" operator with "suicide" "OR" "suicidality" "OR" "suicidal ideation" "OR" "suicidal behavior."

EVIDENCE SYNTHESIS

The initial search yielded 1,458 records, of which 51 research reports that met inclusion criteria were analyzed. These 51 studies sampled a total of 45,942 participants. Clinically, sleep disturbance, psychopathology, and social support have been identified as dominant risk factors for suicidal behavior among pregnant and postpartum women, as well as medical conditions and aversive life events.

CONCLUSION

Monitoring sleep disturbance, depression, and perceived social support is critical given that they are significant risk factors for suicide among perinatal women. Early identification of perinatal women who may be at risk of suicide, although not depressed, is crucial.

LIMITATIONS

The use of tools designed to identify depression to identify suicidal risk, fail to identify women who are at risk but who do not suffer from depression. Other methodological limitations are the lack of longitudinal studies and the complexity of examining suicidal behavior in sample studies.
