FASD Prevention R33 (R33)

14 september 2026 uppdaterad av: Yukiko Washio, Philadelphia College of Osteopathic Medicine

Adapting and Testing Behavioral Intervention to Prevent Fetal Alcohol Spectrum Disorders and Adverse Infant Outcomes (R33)

This R33 application proposes to adapt and test an evidence-based behavioral intervention to decrease polysubstance use (i.e., alcohol and tobacco/cannabis) during pregnancy and lactation and prevent adverse clinical outcomes, including fetal alcohol spectrum disorder (FASD) in South Africa (SA). SA has a long history of social and health disparities, resulting in the world's highest rate of FASD (111.1 per 1,000), where lifelong negative cognitive and physical effects result from prenatal alcohol exposure. FASD is completely preventable if women do not drink during pregnancy. Prenatal alcohol use frequently co-occurs with other substance use, especially tobacco and cannabis. The adverse effect on birth outcomes by alcohol and tobacco use together is worse than either substance alone. Recent evidence from animal models shows that prenatal exposure to both cannabinoids and alcohol potentiate the likelihood of alcohol-induced birth defects. Data from Cape Metropole, SA, showed that all women who reported prenatal alcohol use also tested positive for tobacco use, with 25% also reporting cannabis use. Alcohol use while breastfeeding also occurs at a relatively high rate in SA. Despite tremendous health benefits from breastfeeding, maternal alcohol use while breastfeeding significantly compromises infant development. Contingency management (CM) has been efficacious in reducing prenatal cocaine, alcohol, and tobacco use in the United States (U.S.). The Women's Health CoOp (WHC) is an evidence-based brief intervention addressing women-focused syndemic issues and resulting disparities associated with substance and alcohol use. These evidence-based interventions need to be combined and adapted for addressing maternal polysubstance use and associated health and behavioral issues during pregnancy and lactation in SA.

Experimentell: Intervention
Participants will receive text-based support on health promotion and referral content based on educational components. Participants will be asked to meet research staff on a monthly basis at the clinic to provide a urine sample, fill out timeline follow back on self-reported alcohol and tobacco/cannabis use, and receive contingent incentives if abstinence is verified.

Resultatmått
Åtgärdsbeskrivning
Tidsram
Urinalysis results for alcohol use
Tidsram: From enrollment to the end of treatment at 3 months postpartum
An alcohol metabolite (EtG) will be measured in urine samples. EtG can be detected in the urine up to 5 days after heavy drinking and up to 2 days after light drinking with ≥150 ng/mL for EtG as a cutoff value.
From enrollment to the end of treatment at 3 months postpartum
Urinalysis results for tobacco use
Tidsram: From enrollment to the end of treatment at 3 months postpartum
Biochemical verification of recent tobacco use in urine samples. A tobacco metabolite (cotinine) will be measured in urine samples. The metabolite can be detected up to 3-4 days after use with ≥ 80ng/mL as a cutoff.
From enrollment to the end of treatment at 3 months postpartum
Urinalysis results for cannabis use
Tidsram: From enrollment to the end of treatment at 3 months postpartum
Biochemical verification of recent cannabis use in urine samples. A cannabis metabolite (THC) will be measured in urine samples. The metabolite can be detected up to 28 days after heavy use with ≥50 ng/mL as a cutoff.
From enrollment to the end of treatment at 3 months postpartum

IPD-planbeskrivning

A limited data set in which names and other personal health identifiers are removed will be supplied to researchers on request. The data will be made available after the publication of the study results. Analytic files will be collected in Redcap and then prepared in SPSS, R, SAS, or STATA, with online codebooks giving the variable name, label, type, format, positions, consistency codes, and, if applicable, values and value labels. Requesting access to data will involve drafting an abstract, checking the feasibility relative to the available data, and then seeking the permission of the principal investigator and the team for review, if appropriate. The data sets will be ready for use and can be converted to other analytic tools.
