Thoughts of self-harm in early and late pregnancy in urban South Africa: Investigating prevalence, predictors and screening options

BACKGROUND

Thoughts of self-harm (TSH) are an important marker of mental health risk, and risk for attempted and completed suicide. While there is increasing attention being paid to mental health problems in pregnancy in South Africa (SA), TSH have received less attention despite some cross-sectional studies suggesting that prevalence may be high (12 - 39%). There is a dearth of longitudinal research to inform prevention and treatment.

OBJECTIVES

To examine the rates of TSH across pregnancy in a longitudinal SA cohort and to investigate factors associated with the onset and persistence of TSH, as well as the relationship between TSH, depression and/or anxiety.

METHODS

Women were enrolled in a prospective pregnancy cohort (S1000) in Soweto, SA between 2014 and 2016, and assessed using validated screening measures (Edinburgh Postnatal Depression Scale (EPDS) and State Trait Anxiety Index short form) in early and later pregnancy. Data were available for 649 women. TSH were determined using EPDS item 10. Logistic regression and bifactor models were used to determine factors associated with TSH across pregnancy.

RESULTS

 Of the 649 women, 18% reported TSH at some stage during their pregnancy. Prevalence of TSH was slightly higher in early pregnancy (12.5%) than later in pregnancy (11.6%). TSH were associated with a history of mental illness (adjusted odds ratio (aOR) 4.17; 95% confidence interval (CI) 1.3 - 13.7; p=0.020), concurrent depression (aOR 4.8; 95%CI 2.7 - 8.6; p<0.001); marital stress (aOR 1.74; 95% CI 1.0 - 3.0; p=0.040); and practical support (aOR 0.43; 95% CI 0.2 - 1.0; p=0.040) using a multivariate logistic regression. Bifactor analysis examining depression and anxiety scales showed that TSH contributed the highest variance to a shared depression and anxiety factor in early pregnancy. Logistic regressions showed that early depression was a strong predictor of later reports of TSH.

CONCLUSIONS

 The present study shows that the risk of TSH during pregnancy is relatively common, and starts early during pregnancy. Screening approaches could be simplified to encourage healthcare practitioners working in busy and over-burdened public healthcare settings to engage in identifying at-risk women. Efforts in improving early identification of mental health risk in pregnancy should be matched with strengthening of current treatment and referral options. Since practical support and a good marital relationship reduce the risk of TSH, these may be important avenues of focus for designing interventions.

Antenatal depression and anxiety across pregnancy in urban South Africa

BACKGROUND

Depression and anxiety in pregnancy have negative consequences for women and their offspring. High adversity places pregnant women at increased mental health risk, yet there is a dearth of longitudinal research in these settings. Little is known about the pathways by which these problems emerge or persist in pregnancy.

METHODS

Women were enrolled in a prospective pregnancy cohort in Soweto, South Africa (2014-2016) and assessed using validated measures (Edinburgh Postnatal Depression Scale EPDS ≥13; State Trait Anxiety Index STAI ≥12) in early (T1) and later pregnancy (T2). Data was available for n = 649 women. Multinominal regression modelling was used to determine factors associated with transient versus persistent depression and anxiety across pregnancy. Cross-lagged panel modelling explored direction of effect between depression and anxiety, and stressors.

RESULTS

We found high rates of depression (T1: 27%; T2: 25%) and anxiety (T1: 15%; T2: 17%). Perceiving a partner made one's life harder increased risk of persistent depression (RR 5.92 95% CI [3.0-11.8] p<0.001); family stress increased risk for persistent anxiety (RR 1.71 95% CI [1.1-2.7] p = 0.027). We find evidence of a direct effect of early depression (T1) on later family stress (T2); and early family stress (T1) on later anxiety (T2).

LIMITATIONS

We used screening measures of depression and anxiety rather than clinical interviews.

CONCLUSIONS

Studies which focus only on late pregnancy may underestimate risk. Early identification, in the first trimester, is critical for prevention and treatment. Partner and family stressors are a key intervention target.

Maternal alcohol use and children's emotional and cognitive outcomes in rural South Africa

BACKGROUND

Alcohol use in South Africa (SA) is increasing. The World Health Organization (WHO) states that SA is the third-largest drinking population in Africa, with the highest rate of fetal alcohol syndrome in the world. Internationally, parental drinking during childhood is a risk factor for poor child mental health, behavioural problems and weaker educational outcomes in middle childhood. However, parental alcohol use in Africa is under-researched, and much of the literature on maternal alcohol consumption is restricted to clinical and pregnancy samples.

OBJECTIVES

To investigate alcohol use and hazardous drinking (HD) among mothers/primary caregivers of children aged 7 - 11 years in a rural SA cohort. We explored risk factors for drinking and the association between HD and child behaviour/cognition.

METHODS

The primary outcome measure was the WHO Alcohol Use Disorder Identification Test (AUDIT) using the standardised cut-off for HD (≥8). Secondary measures were the Patient Health Questionnaire Depression Scale (PHQ-9), Patient Health Questionnaire General Anxiety Disorder Scale (GAD-7), Parenting Stress Index, short form (PSI-36), Child Behaviour Checklist (CBCL, parent reported), Kaufman Developmental Assessment Battery (KABC-II) for child cognition, and Neuropsychological Assessment Battery, 2nd edition, subtests (NEPSY-II) for executive function. We compared characteristics of those drinking/not drinking, using χ2 tests, and modelled outcomes on parenting stress, cognitive outcomes and CBCL scores for children using logistic regression analysis. We grouped mothers/caregivers engaged in HD to examine its effect on parent/child outcomes using t-tests to test for significant differences.

RESULTS

Of 1 505 women (1 266 mothers and 239 caregivers) with 1 536 children, 12% reported consuming alcohol and 3% reported HD. Higher maternal/caregiver age (31 - 40 years, adjusted odds ratio (aOR) 0.57 (95% confidence interval (CI) 0.4 - 0.9); >41 years, aOR 0.30 (95% CI 0.2 - 0.5)), education (matriculation, aOR 0.49 (95% CI 0.3 - 0.9); post matriculation, aOR 0.30 (95% CI 0.1 - 0.6)), and a stable relationship with the father (aOR 0.6 (95% CI 0.4 - 1.0)) were associated with no alcohol use. Food insecurity increased the odds of alcohol use (aOR 1.52 (95% CI 1.1 - 2.1)), while parental mental health (parenting stress, anxiety) and child mental health problems were associated with approximately double the odds of consuming alcohol in univariate analysis. Children of HD mothers/caregivers had higher mean scores for psychological problems (CBCL total score: no HD (mean 45.0) v. HD (mean 48.9); p=0.029) and lower cognitive scores (KABC Learning Scale: no HD (mean 14.3) v. HD (mean 12.8); p=0.017).

CONCLUSIONS

While HD rates were low, maternal/caregiver alcohol use negatively impacted on parenting and children's behavioural/cognitive outcomes. International evidence suggests that integrated approaches engaging parents and families may be more effective for parent-child outcomes than individual psychiatric or medical care for the parent on their own.

Intimate partner violence, HIV, and mental health: a triple epidemic of global proportions

Intimate partner violence (IPV) is a global health problem of epidemic proportions, affecting a third of women across the globe and as many as 60% in heavily affected regions of Africa. There is strong evidence that risk of IPV is heightened in HIV-infected women, and emerging evidence linking experiencing IPV and/or HIV to a higher likelihood of experiencing mental health problems. This triple burden makes women in Africa, living in the epicentre of HIV, all the more vulnerable. In this synthesis, this study reviewed literature pertaining to the overlap of IPV, HIV, and mental health problems. It presents a series of geographical maps illustrating the heavy burden of IPV and HIV globally, and how these coincide with a growing prevalence of mental health problems in Africa. Furthermore, it presents evidence on: the association between IPV and HIV, shared risk factors, and health consequences. This synthesis sheds light on the fact that ∼30% of women are affected by these three burdens concurrently, and the need for intervention is essential. Promising large scale interventions which have taken place in Africa are described, and evidence is presented in support of integrated versus targeted screening.

Towards a family-centered approach to HIV treatment and care for HIV-exposed children, their mothers and their families in poorly resourced settings

This article provides a summary of emerging psychosocial evidence relevant to the success of comprehensive family-centered approaches to HIV prevention, treatment, care and support programs in poorly resourced settings. This report synthesizes current evidence on maternal, paternal and family experiences of HIV prevention, diagnosis, treatment, adherence and disclosure, with special focus on HIV-infected mothers and HIV-exposed children. Taking a developmental approach, we explore the current challenges and opportunities towards a family-centered approach within the continuum of HIV treatment and care, beginning in pregnancy and following the course of childhood. The discussion is limited to early and middle childhood and excludes discussion of special issues emergent in adolescence, which would warrant discussion outside the scope of this article. Attention is drawn to the complexity of problems arising within the family context and the need for improvements in the integration of aspects of treatment, care and support. While this article focuses on examples from sub-Saharan Africa, the lessons learnt and future challenges outlined are applicable to most low- and middle-income countries, and to poorly resourced contexts in higher-income countries.
