BPA, obesity link? Maybe it’s just due to fat

In a special obesity issue of JAMA, researchers reported on results from a cross-sectional study of nearly 3000 children from primary school age to late teens, finding those with the highest urinary concentration of BPA had twice the risk of obesity of those with the lowest levels.

Controlling for many confounders including physical inactivity and caloric intake, the researchers showed children in the highest quartile for BPA had a prevalence of obesity of 22% compared to 10% in the lowest quartile, with the association statistically significant only for Caucasians.
