About this study
Official title: Evaluating Public Policy: A Case Study of the Green Prescription POLVERT (Green Policy - Evaluation and Results)
Numerous studies have highlighted the harmful effects of pesticide exposure during the prenatal period. Food is one of the main vectors of exposure to pesticides, particularly glyphosate, which is the most widely used herbicide. Observational studies have highlighted their effects on health, but few interventional studies have been conducted to identify effective interventions to reduce or eliminate environmental risks. In 2022, the City of Strasbourg implemented the "Ordonnance Verte" (Green Prescription) program, giving all pregnant women in the city access to a weekly basket of organic and local vegetables for several months, as well as awareness-raising workshops on endocrine disruptors and healthy eating. The objective of this study is to assess whether this type of program reduces pregnant women's exposure to pesticides compared to women who continue to eat according to their usual habits. If conclusive, this type of assessment would play a key role in facilitating the rollout of similar initiatives on a larger scale and protecting the health of pregnant women and future children.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Consumption of organic vegetablesBehavioural
Consumption of organic vegetables or non-organic for control group (according to their usual habits) for 2 weeks
| Study group | Role | What they receive |
|---|---|---|
| Control | No intervention | Vegetable consumption according to habits |
| Intervention | Experimental | Consumption of organic vegetables Receives: Behavioral: Consumption of organic vegetables |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in urinary pesticide concentrations over the two-week study period in the intervention group
Measured as the difference in pesticide levels before and after the intervention
Measured: Day 0 and at 2 weeks
Difference in urinary pesticide concentrations between the two groups
Measured as the difference in pesticide levels in intervention vs. control groups
Measured: Day 0 and at 2 weeks
