Study Summary
The purpose of this research is to understand whether and how pregnant women may be exposed to glyphosate, the active ingredient in a common herbicide. The researchers aim to assess glyphosate exposure among pregnant women in Idaho, and to attribute that exposure to agricultural and dietary sources. Pregnant women who live either near or far from glyphosate-treated fields will be recruited for study inclusion, and exposure will be assessed via urinary biomonitoring on a weekly basis throughout pregnancy. Each participant will also take part in a two-week dietary intervention, during which they will receive one week of organic food and one week of conventional food, in a crossover design. Urinary biomonitoring will occur on a daily basis during the dietary intervention phase. The researchers hypothesize that women who live near agricultural fields treated with glyphosate will have higher exposures than those who live in non-agricultural regions, and that consumption of an organic diet will reduce exposures in both groups. All study components will be completed with no face-to-face interaction to eliminate all coronavirus (COVID-19) related risks.
Primary Outcome
We collected 531 daily first morning void urine samples. We aliquoted 0.6 mL of each participant's seven daily urine samples to form a composite sample intended to represent each participant's mean glyphosate exposure during each week of the dietary intervention For all 39 participants there was one weekly composite urine sample from the conventional diet period and one weekly composite urine sample from the organic diet period. These 78 composite urine samples were analyzed for glyphosate conce
