BPA study on mice shows parenting change and links to humans
COLUMBIA - New University of Missouri studies show exposure to a common chemical could have an effect on how you parent.
The research uses mice and centers on the chemical Bisphenol-A, or BPA, and shows it can adversely affect parenting behaviors.
University of Missouri researchers used monagomous, biparental California mice to study the effects of BPA.
Biparental care for offspring occurs in a minority of species including humans. The California mice were used because they carry this trait and can therefore be linked to humans.
The mice were fed BPA in their daily diets, which can act as hormones in the body.
Researchers found that pups born to parents who were exposed to BPA received decreased parental care by both the mother and father.
They said this is important because results could link to human parenting as well.
California mice exposed to BPA spent less time feeding and interacting with their babies.
Researcher Cheryl Rosenfeld said this study is significant because if the offspring are receiving less care, then they could experience other cognitive disorders down the line.
Rosenfeld said they need to serve as a model for how we start studying the effect of BPA on parenting in humans.
