A new study published in the Journal of the American Medical Association (JAMA, September 9th issue) brings up the concern that many have about the effects of bisphenyl A (BPA) in our food supply. This time it concerns childhood obesity.
BPA exposure is ubiquitous in the U.S. population with 92.6 percent of persons over the age of 6 years having detectable BPA levels in their urine. A study of indoor and outdoor air, solid and liquid food in preschool-aged children suggested that dietary sources constitute 99% of BPA exposure.
In the JAMA study, researchers examined the association between urinary BPA concentrations and body mass in children. They studied 2,838 children, ages 6 through 19 years in a randomly selected sample from the 2003-2008 National Health and Nutrition Examination Surveys.
