Yet another study shows that bisphenol A (BPA) exposure during pregnancy is bad news. This new observational study examined BPA exposure in the workplace and the subsequent affect on baby birth weight. After looking at various workplace situations, the researchers found that when mothers-to-be are exposed to BPA, there’s some preliminary evidence that shows the offspring from these mothers may experience adverse fetal growth. In other words, BPA is linked with lower birth weights.

The correlation between a lower birth weight and BPA exposure was affected by the amount of BPA exposure. For example, mothers directly exposed to high BPA levels at their place of work had the smallest offspring. Smaller babies were less likely, but still occurred, when mothers-to-be were exposed to low levels of BPA and mothers whose partner experienced high levels of BPA at work. The least affected babies were born to mothers whose partners worked around low levels of BPA exposure. Basically, this study tells us that the highest levels of BPA exposure were the most associated with lower birth weights. As BPA exposure lessened, mothers were less likely to give birth to a low birth weight baby.

This study was conducted by Kaiser Permanente Division of Research, funded by National Institute for Occupational Safety and Health and published in the current online issue of Reproductive Toxicology.
