What this trial studies

This clinical trial investigates the effects of prenatal choline supplementation on pregnant women who are heavy drinkers, aiming to mitigate the adverse impacts of prenatal alcohol exposure on fetal development. Participants will receive either choline bitartrate or a placebo from the start of antenatal care until delivery. The study is conducted in Cape Town, South Africa, where the rates of heavy drinking during pregnancy are notably high. The trial builds on previous animal studies suggesting that choline can improve growth and neurodevelopment in infants exposed to alcohol in utero.

Who should consider this trial

Good fit: Ideal candidates are pregnant women aged 18 or older, less than 20 weeks gestation, who are heavy drinkers and have low dietary choline intake.

Not a fit: Patients who are not heavy drinkers or those with serious pre-existing medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a nutritional intervention to improve outcomes for infants at risk of fetal alcohol spectrum disorders.

How similar studies have performed: Previous studies have shown promising results with choline supplementation in animal models, but this approach in humans is still being explored.
