I did a previous post on the dangers of BPA found in food cans and even receipts from cash machines.  A new study reported on today found obesity levels higher in children with higher levels of BPA in their urine.

..But the study does hint that causes of childhood obesity may be more complicated, he added. He said it is the first national research to tie a chemical from the environment to childhood obesity, and seems to echo what some studies have seen in adults.

One puzzling result: Significant differences were detected only in white children. For black and Hispanic kids, obesity rates were similar for those with the lowest levels of BPA as those with the largest amount. The researchers couldn’t explain that finding.

The study was released Tuesday and is in Wednesday’s issue of the Journal of the American Medical Association.

Some experimental studies on animals have found that BPA can aid obesity by disrupting metabolism and helping to make fat cells larger. And studies have suggested a possible tie between urinary BPA levels and obesity-related illnesses in adults, including diabetes and heart disease.
