What this trial studies

This interventional public-health project enrolls pregnant women registered in the Green Prescription (Ordonnance Verte) program in Strasbourg and provides weekly baskets of local organic vegetables alongside awareness workshops about endocrine disruptors and healthy eating. Researchers will compare biomarkers of pesticide exposure in participants receiving the program to pregnant women who continue their usual eating habits. Eligible participants are adult pregnant women under 32 weeks, fluent in French and registered in the program; women working in or living with someone in agriculture are excluded. The design aims to measure whether the program reduces prenatal pesticide exposure and to generate evidence to inform broader policy rollout.

Who should consider this trial

Good fit: Ideal candidates are pregnant women under 32 weeks of gestation who are over 18, fluent in French, registered with the Ordonnance Verte program, covered by social security, able to consent, and with telephone and internet access.

Not a fit: Women already consuming exclusively organic diets, those past 32 weeks of pregnancy, and those working in or living with someone in agriculture are unlikely to gain additional exposure reduction from this intervention.

Why it matters

Potential benefit: If successful, the program could lower pregnant women's pesticide exposure and reduce risks to fetal development while providing evidence to support wider public-policy rollouts.

How similar studies have performed: Observational studies link prenatal pesticide exposure to harm, and a few small dietary intervention trials have reduced exposure, but large interventional public-policy evaluations like this are relatively novel.
