Predictors of alcohol and other drug use among pregnant women in a peri-urban South African setting

Background: Alcohol and other drugs (AOD) use among pregnant women have been associated with adverse health outcomes for mother and child, during and after pregnancy. Factors associated with AOD use among women include age, poverty, unemployment, and interpersonal conflict. Few studies have looked at demographic, economic, and psychosocial factors as predictors of AOD use among pregnant women in low-income, peri-urban settings. The study aimed to determine the association between these risk factors and alcohol and drug use among pregnant women in Hanover Park, Cape Town. Methods: The study was undertaken at a Midwife Obstetric Unit providing primary-level maternity services in a resource-scarce area of South Africa. 376 adult women attending the unit were recruited and a multi-tool questionnaire administered. Demographic, socioeconomic and life events data were collected. The Expanded Mini-International Neuropsychiatric Interview Version 5.0.0 was used to assess alcohol abuse and other drugs use, depression, anxiety, and suicidal ideation. Descriptive and bivariate analyses were conducted to examine the associations between predictor variables. Non-parametric tests, Wilcoxon sum of rank test, Fisher Exact and two sample T test and multicollinearity tests were performed. Logistic regression was conducted to identify associations between the outcome of interest and key predictors. A probability value of p ≤ 0.05 was selected. Results: Of the total number of pregnant women sampled, 18 % reported current AOD use. Of these, 18 % were currently experiencing a major depressive episode, 19 % had a current anxiety diagnosis, and 22 % expressed suicidal ideation. Depression, anxiety, suicidality, food insecurity, interpersonal violence, relationship dynamics, and past mental health problems were predictors of AOD use. Conclusions: This study has confirmed the vulnerability of pregnant women in low-income, peri-urban settings to alcohol abuse and other drugs use. Further, the association between diagnosed depression and anxiety, suicidality, and AOD use among these women may reflect how complex environmental factors support the coexistence of multiple mental health problems. These problems place mothers and their infants at high risk for poor health and development outcomes. The results have implications for planning appropriate interventions

Identifying and treating maternal mental health difficulties in Afghanistan: A feasibility study

Background: The disproportionately high burden of mental disorders in low- and middle-income countries, coupled with the overwhelming lack of resources, requires an innovative approach to intervention and response. This study evaluated the feasibility of delivering a maternal mental health service in a severely-resource constrained setting as part of routine service delivery. Methods: This exploratory feasibility study was undertaken at two health facilities in Afghanistan that did not have specialist mental health workers. Women who had given birth in the past 12 months were screened for depressive symptoms with the PHQ9 and invited to participate in a psychological intervention which was offered through an infant feeding scheme. Results: Of the 215 women screened, 131 (60.9%) met the PHQ9 criteria for referral to the intervention. The screening prevalence of postnatal depression was 61%, using a PHQ9 cut-off score of 12. Additionally, 29% of women registered as suicidal on the PHQ9. Several demographic and psychosocial variables were associated with depressive symptoms in this sample, including nutritional status of the infant, anxiety symptoms, vegetative and mood symptoms, marital difficulties, intimate partner violence, social isolation, acute stress and experience of trauma. Of the 47 (65%) women who attended all six sessions of the intervention, all had significantly decreased PHQ9 scores post-intervention. Conclusion: In poorly resourced environments, where the prevalence of postnatal depression is high, a shift in response from specialist-based to primary health care-level intervention may be a viable way to provide maternal mental health care. It is recommended that such programmes also consider home-visiting components and be integrated into existing infant and child health programmes. Manualised, evidence-based psychological interventions, delivered by non-specialist health workers, can improve outcomes where resources are scarce

Stepped Care for Maternal Mental Health: A Case Study of the Perinatal Mental Health Project in South Africa

As one article in a series on Global Mental Health Practice, Simone Honikman and colleagues from South Africa provide a case study of the Perinatal Mental Health Project, which delivered mental health care to pregnant women in a collaborative, step-wise manner, making use of existing resources in primary care

Domestic and intimate partner violence among pregnant women in a low resource setting in South Africa: a facility-based, mixed methods study

Background Rates of violence against women are reported to be highest in Africa compared to other continents. We aimed to determine associations between mental illness, demographic, psychosocial and economic factors with experience of intimate partner violence (IPV) among pregnant women in a low resource setting in Cape Town and to explore the contextual elements pertaining to domestic violence. Methods We recruited adult women attending antenatal services at a primary-level maternity facility. Demographic, socioeconomic and psychosocial data were collected by questionnaire. The Expanded Mini- International Neuropsychiatric Interview (MINI) Version 5.0.0 was used to assess mental health status and the Revised Conflict Tactic Scale (CTS2) used to assess IPV in the six months prior to the study. Non-parametric tests, Wilcoxon sum of rank test, Fisher Exact and two sample T test and multicollinearity tests were performed. Descriptive, bivariate and logistic regression analyses were conducted to identify associations between the outcome of interest and key predictors. A probability value of p ≤ 0.05 was selected. From counselling case notes, a thematic content analysis was conducted to describe contextual factors pertaining to forms of domestic violence (DV). Results The prevalence of IPV was 15% of a sample of 376 women. Women who were food insecure, unemployed, in stable but unmarried relationships, had experienced any form of past abuse and were not pleased about the current pregnancy were more likely to experience IPV. MINI-defined mental health problems and a history of mental illness were significantly associated with IPV. Qualitative analysis of 95 counselling case notes revealed that DV within the household was not limited to intimate partners and, DV in this context was often perceived as ‘normal’ behaviour by the participants. Conclusions This study contributes towards a greater understanding of the risk profile for IPV amongst pregnant women in low-income settings. Adversity, including food insecurity and mental ill-health are closely associated with IPV during the antenatal period. Advocates against violence against pregnant women are advised to consider that violence in the home may be perpetrated by non-intimate partners and may by enabled by a pervasive belief in the acceptability of the violence

Perinatal Mental Health project

The Perinatal Mental Health Project (PMHP) addresses mental illness among pregnant and postnatal women and girls. The aim of PMHP is to ensure all women in South Africa have access to mental health care during and after pregnancy, as a routine part of their health care. Maternal mental illnesses, particularly common mental disorders such as depression and anxiety, are very common in low-income and informal settings. While maternal mental illness affects 10% to 15% of women in developed countries, prevalence is almost 40% in South Africa. Most of the women in South Africa who experience maternal mental illness are poor, from disadvantaged communities who face many challenges in accessing health services and treatment

Comparison of mental health screening tools for detecting antenatal depression and anxiety disorders in South African women.

Antenatal depression and anxiety disorders are highly prevalent in low and middle-income countries. Screening of pregnant women in primary care antenatal settings provides an opportunity for entry to care, but data are needed on the performance of different screening tools. We compared five widely-used questionnaires in a sample of pregnant women in urban South Africa.Pregnant women attending a primary care antenatal clinic were administered five tools by trained research assistants: the Edinburgh Postnatal Depression Scale (EPDS), the Patient Health Questionnaire (PHQ-9), the Kessler Psychological Distress scale (K10) and a shortened 6-item version (K6), the Whooley questions and the two-item Generalised Anxiety Disorder scale (GAD-2). Following this, a registered mental health counsellor administered the MINI Plus, a structured clinical diagnostic interview. The Area Under the Curve (AUC) from Receiver Operator Characteristic curve analysis was used to summarise screening test performance and Cronbach's α used to assess internal consistency.Of 376 participants, 32% were diagnosed with either MDE and/or anxiety disorders. All five questionnaires demonstrated moderate to high performance (AUC = 0.78-0.85). The EPDS was the best performing instrument for detecting MDE and the K10 and K6 for anxiety disorder. For MDE and/or anxiety disorders, the EPDS had the highest AUC (0.83). Of the short instruments, the K10 (AUC = 0.85) and the K6 (AUC = 0.85) performed the best, with the K6 showing good balance between sensitivity (74%) and specificity (85%) and a good positive predictive value (70%). The Whooley questions (AUC = 0.81) were the best performing ultra-short instrument. Internal consistency ranged from good to acceptable (α = 0.89-0.71). However, the PPV of the questionnaires compared with the diagnostic interview, ranged from 54% to 71% at the optimal cut-off scores.Universal screening for case identification of antenatal depression and anxiety disorders in low-resource settings can be conducted with a number of commonly used screening instruments. Short and ultra-short screening instruments such as the K6 and the Whooley questions may be feasible and acceptable for use in these settings

CommentaryImproving child outcomes through maternal mental health interventions

This commentary will provide a general overview of the public health considerations of maternal mental illness, both from a global perspective as well as from the South African context. The paper will  outline the consequences of maternal mental illness for mothers as well as their offspring, through the life stages from pregnancy until adulthood. The paper then describes the Perinatal Mental Health Project (PMHP), an intervention that addresses maternal mental health  in Cape Town, South Africa. The evidence emerging from this example contributes to the case for integrating maternal mental health into the mainstream health environment.Journal of Child and Adolescent Mental Health 2010, 22(2): 73–8
