Parental exposure to BPA during pregnancy associated with decreased birth weight in offspring
Date:5/5/2011

rs (from industries without BPA exposure), including their spouses and offspring, were recruited from 2003-2008.

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.

This study is the fourth in a series published by Dr. Li and his colleagues that examine the effect of BPA in humans. The first study, published in November 2009 in the Oxford Journals' Human Reproduction, found that exposure to high levels of BPA in the workplace increases the risk of reduced sexual function in men. The second study, published in May 2010 in the Journal of Andrology, found that increasing BPA levels in urine are associated with worsening male sexual function. The third study, published in Fertility and Sterility, showed that an increasing urine BPA level was significantly associated with decreased sperm concentration, decreased total sperm count, decreased sperm vitality and decreased sperm motility.

Funded by the U.S. National Institute of Occupational Safety and Health, this latest study adds to emerging human evidence questioning the safety of BPA, a chemical created in the production of polycarbonated plastics and epoxy resins found in baby bottles, plastic containers, the linings of cans used for food and beverages, and in dental sealants.

The researchers explained that BPA is believed by some to be a highly suspect human endocrine disrupter, likely affecting both male and female rep
