A new study links bisphenol S (BPS) and bisphenol F (BPF) to a potential increase in childhood obesity. Analyzing data from the U.S. National Health and Nutrition Examination Survey, researchers from the NYU School of Medicine discovered that children ages 6 to 19 with higher levels of BPS and BPF in their urine were more likely to be obese than those with lower levels.
The study, "Urinary bisphenols and obesity prevalence among US children and adolescents," was published in the Journal of the Endocrine Society on July 25.
BPS and BPF typically replace bisphenol A (BPA), which has been called an “endocrine disruptor” and linked with health risks in some studies. BPA is found in polycarbonate used to produce water bottles and food and beverage containers as well as other consumer goods. Epoxy resins, which also contain BPA, are used to coat metal containers.
BPA has been banned in baby bottles in the United States and Europe for several years out of concern that it may have health effects on developing minds and bodies. Although BPA has been deemed safe “for currently approved uses in food containers and packaging” by FDA, consumer goods companies bowed to public concern (and sought a marketing advantage) by replacing BPA with other bisphenol chemicals and touting "BPA-free" on packaging. Soon after, however, scientists began warning that the alternative chemicals may create problems of their own.
