Parental exposure to plastic chemical linked to kid's lower birth weight


May 6, 2011 - Washington

A new study has found that parental exposure to bisphenol A (BPA)- a chemical used to make polycarbonate plastic and epoxy resins - during Pregnancy is associated with decreased birth weight of offspring.

Kaiser Permanente researchers explained that there was a greater magnitude of decrease in birth weight in children whose mothers were directly exposed to high BPA levels in the workplace during Pregnancy.

The effects were also found on infants whose mothers had BPA exposure through father's high occupational BPA exposure.

The study provides preliminary evidence that maternal exposure to BPA during Pregnancy may have an adverse effect on fetal growth, said De-Kun Li, the principal investigator of the study.

The study population was identified from a larger study of more than 1,000 male and female workers in factories in China.

It compared workers in BPA-exposing facilities with a control group of workers in factories where no BPA was present.

Mothers in the mother-exposed group worked for at least three months during Pregnancy.

The researchers explained that it is possible that offspring in this group had relatively higher levels of in-utero BPA exposure than those in other groups.

Spouses of exposed fathers, although not directly exposed to BPA in the workplace, were more likely to have a higher BPA exposure level than women in the unexposed group.

Exposure in this group could occur through exposure to contaminated clothing, through workplace visits with spouses, and through residence proximity to factories, explained the researchers.

The study has been published in the current online issue Reproductive Toxicology.
