High Glyphosate Levels in Mothers Leads to Shorter Pregnancies and Smaller Babies – New Ongoing Study

Children’s Environmental Health Network (CEHN) announced Tuesday new evidence highlighting growing concern over sharply rising herbicide use and risks to pregnant women and children living in the rural Midwest.

One ongoing study of pregnant women in an Indiana obstetric practice has found glyphosate (aka Roundup) in the urine of over 90% of test subjects so far. The study will be peer-reviewed and published later in 2017. The lead scientist of the study, Dr. Paul Winchester, stated; “In our study, which is ongoing, mothers with relatively higher levels of glyphosate were more likely to have shorter pregnancies and deliver babies with lower birth-weight, outcomes that everyone should be concerned about.”

In his presentation at the CEHN Research Conference, Dr. Winchester will point out that “Shorter pregnancies with relatively lower birth weights have been linked to lower cognitive ability later in life and higher risk of metabolic syndrome.”

The initial data from the study shows that glyphosate has been found in the urine of 63 of 69 (91%) pregnant women receiving prenatal care at an Indiana obstetric practice, at a mean level of 3.44 ug/l. Surprisingly, higher glyphosate levels were associated with reductions in gestation-adjusted birth weight (r’s= -0.24, p=0.045) and gestation age (r’s= -0.25, p=0.035). Women living in rural areas had higher mean glyphosate levels than women in urban/suburban regions (mean glyphosate level of 4.21 vs. 3.3, p=0.004), suggesting an additional route of exposure associated with proximity to corn and soybean production fields.

In 2016 Sustainable Pulse reported that glyphosate had been found in the urine of 93% of the American public during a unique testing project that started in 2015 at the University of California San Francisco (UCSF).
