Risk factors for substance use in pregnant women in South Africa

Objectives. To study the prevalence of alcohol and substance use in a South African antenatal population and its correlates with socio-demographic factors, depression and perceived stress. Methods. A prospective self-report study on all women presenting for their first antenatal visit who consented to the study at a midwife obstetric unit (MOU) in the East Metropole district, Cape Town, using the Alcohol Use Disorders Identification Test (AUDIT), Drug Use Disorders Identification Test (DUDIT), Edinburgh Depression Scale (EDS) and Perceived Stress Scale (PSS). Statistical analyses using the chi-square test, separate one-way analyses of variance (ANOVA) and logistic regression analyses were performed as appropriate. Outcome measures were depression, alcohol use and substance use. Results. The questionnaire was completed by 323 women. During pregnancy 36.8% of women smoked, 20.2% used alcohol and 4% used substances. Using EDS cut-off scores of 12 and 15, respectively, 48.9% and 33.6% of the sample had scores consistent with major depression. An EDS cut-off score of 12 was significantly associated with both alcohol use (25.9% v. 15.2%, p=0.019) and risky drinking (76.9% v. 36.8%, p=0.04), while an EDS cut-off score of 15 was significantly associated with substance use (8.2% v. 1.4%, p=0.004) as well as alcohol dependence (23.1% v. 3.1%). Conclusions. We found high rates of both alcohol abuse and antenatal depression, and a significant association between depression, substance use and alcohol abuse; EDS scores greater than 12 could be used to identify women at risk of alcohol dependence and/or substance abuse

Challenges and controversies in prenatal genetic screening in the South African context

Prenatal genetic screening is an integral part of general antenatal care and is regarded as standard of care for all pregnant women. All pregnant women < 20 weeks gestation should be offered some form of genetic screening and this should be discussed in an extensive pre-test counselling session. Late screening (after 20 weeks) may also be offered but will be limited by management options. Cell-free DNA testing has added another dimension to the landscape of prenatal screening but has to be appropriately used for the correct indication. Interpretation of risk for Down’s syndrome is a critical component of the screening process. A guideline would be to regard screening risks in absolute terms as there is no provision made to interpret risk in relative risk terms. An important safeguard to overcome the “relative risk” conundrum would be to inform all patients during pre-test counselling of an intermediate risk category generally between 1:300-1:1000 where cfDNA testing may be considered, at the parents’ own discretion. If the screening risk is <1:1000, no further testing is advised as this risk is deemed very low. A screening risk for Down’s syndrome >1:300 will be deemed high risk, as is presently the case.http://www.journals.co.za/content/journal/medogam2018Obstetrics and Gynaecolog
