New study shows BPA may cause teen and childhood obesity

Posted: Updated:

KENNEWICK, Wash. -- A new study in the Journal Of The American Medical Association suggests that Bisphenol A, also known as BPA's maybe causing obesity in children and teenagers.

BPA's are estrogen like chemicals found in plastic bottles, some plastic containers, soda cans and canned food. According to the CDC, 92% of Americans have detectable levels of BPA in their blood.

The new study looked at data from 2,838 teenagers and kids between the ages of six and nine. Researchers found that 22% of those with the highest levels of BPA's were obese, compared to ten percent of those with the lowest levels.

A study published last year, also based on CDC data, found similar patterns of obesity among American adults exposed to BPA.

"Now the study did not prove that BPA is causing obesity, it may be that people that are obese are eating and drinking more foods that have BPA in them," says Dr. Amy Person, the Benton Franklin Heath District Officer.

Dr. Person says some good ways to lessen your exposure include buying fresh or frozen food instead of canned food. Person also recommends you avoid microwaving your food in plastic containers if possible.
