Alcohol and Other Drug Use during Pregnancy among Women Attending Midwife Obstetric Units in the Cape Metropole, South Africa

Petal Petersen Williams; Esme Jordaan; Catherine Mathews; Carl Lombard; Charles Parry

Little is known about the nature and extent of alcohol and other drug (AOD) use among pregnant women in Cape Town, South Africa, despite the very high levels of AOD use in this part of the country. A cross-sectional survey was conducted among pregnant women attending 11 Midwife Obstetric Units (MOUs) in greater Cape Town. A two-stage cluster survey design was used. In total, 5231 pregnant women were screened to assess self-reported prevalence estimates. Of these, 684 (13.1%) were intentionally subsampled and completed an interviewer-administered questionnaire and provided a urine sample for biological screening. Urinalyses showed that 8.8% (95% CI: 6.7–10.9) of the subsample tested positive for at least one illicit drug. This is higher than the self-reported prevalence (3.6%). In addition, 19.6% (95% CI: 16.3–22.8) of the sub-sample tested positive for alcohol which is lower than the self-reported prevalence (36.9%). There are high levels of substance use among pregnant women attending public sector antenatal clinics. There is a need for routine screening for AOD use and appropriate responses depending on the womens level of risk.

Formative work to inform interventions aimed at addressing drug and sexual risk behaviours among men who have sex with men (MSM) in South Africa highlighted the need to target drug-using MSM with prevention interventions addressing both sexual and drug-related HIV risk. From 2007, in collaboration with two local NGOs, intervention activities were rolled out to vulnerable drug-using MSM. Over the first two years, 3475 drug-using MSM were reached through community outreach that promotes HIV/AIDS prevention and addresses drug risk behaviours and 745 among them were tested for HIV and received their results and 239 of them were referred from HCT to other services. Additionally, 66 individuals were trained to promote HIV/AIDS prevention services and 15 were trained in HCT. Twelve new targeted condom and lubrication services and 7 new HCT outlets were established. MSM reported a variety of high-risk activities including not using condoms for anal sex, having sex while under the influence of alcohol or drugs and sharing needles (among injection drug users). However, MSM were willing to develop risk reduction strategies. Year one and two of the intervention has demonstrated the willingness of the NGOs to broaden their service delivery, improved integration of drug treatment, HIV intervention and other services, and has shown positive results across a number of risk behaviours among MSM.

The aim of this article is to describe the prevalence of risk for developing mental health problems in a large survey of high school students in the Western Cape Province in South Africa. The study population comprised students in Grades 8, 9, and 10 attending public schools in the Western Cape Province. Schools were randomly sampled proportional to total school size (all grades). A total of 227 schools and a total of 20,855 students completed the survey. Overall, 14.9% of students were categorised as ‘high risk’ for mental health problems. A significantly higher proportion of female participants were in the ‘high-risk’ category (18.5%; confidence interval = [17.2, 19.8]) than male participants (10.1%; confidence interval = [9.3, 10.8]). Female students who reported more days absent from school in the previous school quarter were more likely to be in the ‘high-risk’ category for mental health problems. Findings highlight the need for screening for mental health problems among adolescents attending high school in South Africa, and the need to develop intervention programmes for students at risk of mental health problems.

BACKGROUND Optimizing the effectiveness of substance use disorder (SUD) treatment is critical in low-and middle-income countries (LMICs) with limited opportunities for SUD treatment. This is the first study to identify targets for interventions to improve the quality of SUD treatment in a LMIC. METHOD We explored correlates of three indicators of treatment quality (treatment engagement, completion and abstinence at treatment exit) using data from a SUD performance measurement system implemented in the Western Cape Province of South Africa. The sample included data from 1094 adult treatment episodes representing 53% of the treatment episodes in 2016. Using multivariate logistic regression analyses, we modeled socio-demographic, substance use and program correlates of treatment engagement, completion, and abstinence at treatment exit. RESULTS Overall, 59% of patients completed treatment (48% of patients from outpatient services). Treatment completion was associated with greater likelihood of abstinence at treatment exit. Patients were more likely to complete treatment if they engaged in treatment, were older, and had more severe drug problems (characterized by daily drug use and heroin problems) and attended programs of shorter duration. Residential treatment was associated with greater likelihood of treatment engagement, completion, and abstinence at treatment exit. CONCLUSION Improving rates of outpatient treatment completion will enhance the effectiveness of South Africas SUD treatment system. Interventions that promote engagement in treatment, particularly among younger patients; reduce program length through referral to step-down continuing care; and ensure better matching of drug problem to treatment level and type could improve rates of treatment completion.

Abstract Introduction and Aim To report data on the implementation of alcohol policies regarding availability and marketing, and drink driving, along with ratings of enforcement from two small high‐income to three high‐middle income countries, and one low‐middle income country. Method This study uses the Alcohol Environment Protocol, an International Alcohol Control study research tool, which documents the alcohol policy environment by standardised collection of data from administrative sources, observational studies and interviews with key informants to allow for cross‐country comparison and change over time. Results All countries showed adoption to varying extents of key effective policy approaches outlined in the World Health Organization Global Strategy to Reduce the Harmful Use of Alcohol (2010). High‐income countries were more likely to allocate resources to enforcement. However, where enforcement and implementation were high, policy on availability was fairly liberal. Key Informants judged alcohol to be very available in both high‐ and middle‐income countries, reflecting liberal policy in the former and less implementation and enforcement and informal (unlicensed) sale of alcohol in the latter. Marketing was largely unrestricted in all countries and while drink‐driving legislation was in place, it was less well enforced in middle‐income countries. Conclusion In countries with fewer resources, alcohol policies are less effective because of lack of implementation and enforcement and, in the case of marketing, lack of regulation. This has implications for the increase in consumption taking place as a result of the expanding distribution and marketing of commercial alcohol and consequent increases in alcohol‐related harm.

Abstract Aims: There is limited literature on the challenges encountered during household surveys on alcohol consumption in low- and middle-income countries. This paper aims to describe the problems encountered during data collection for the IAC study in South Africa and put forward recommendations for addressing identified challenges. Methods: Data on methodological and other challenges emerged from feedback sessions held with fieldworkers, supervisors, observations made of and follow up meetings with project investigators, based on the pilot and main study of 2844 adults and adolescents in Tshwane (South Africa). Results: Challenges identified included the following: delays in software development which resulted in postponement of data collection with subsequent budgetary implications; difficulties in identifying the full range of alcohol beverages during the adaptation of the questionnaire as manufacturers sometimes changed quantities and packaging to enhance sales; a resultant lengthy questionnaire which negatively impacted on participation; potential participants sometime being afraid to allow fieldworkers onto premises due to high crime rates in many participating areas and religious beliefs concerning alcohol consumption that prevented some parents from consenting to their adolescent children’s participation. Conclusion: When planning community surveys on alcohol use, it is important to anticipate and prepare for these and other challenging conditions that arise in the preparation for, and execution of fieldwork.
