This Status Report is an update of the panel’s previous report on pregnancy outcomes, which was released in July. This is a broader look than the previous report, using a linkage between C8 Health Project data and state birth records to, among other things, follow women from one residence to another and estimate their C8 intake from local water supplies.
The Science Panel’s summary says of this new analysis, looking at stillbirths, pregnancy-induced hypertension, preterm birth, and several indicators of the infant’s size, including low birth weight and average birth weight:
Overall, these results provide little or no support for an association between PFOA exposure and any adverse effects on pregnancy.
But it also includes these interesting tidbits:
… But there was some indication that male infants with the highest exposure to PFOA weighed slightly less at birth.
… There was some indication that female infants with the highest exposure to PFOA weighed slightly less at birth.
The panel said of these findings:
These small differences in birth weight with conflicting patterns across the two analyses, one limited to male births and the other [to] female births, are of uncertain significance.
