New research has shown a potential association between the chemical bisphenol A (BPA) and childhood obesity.
American researchers noted that children with elevated levels of BPA in their urine were more likely to be overweight when compared to children whose urine contained lower levels of the chemical, Reuters noted.
The researchers analyzed the urine of 3,000 children between the ages of 9 years and 16 years. A third of the children in the survey were overweight, and almost a fifth were considered obese.
A little more than 10% of children with low BPA levels were obese. But 22% with higher BPA levels in the urine were obese.
At this point, the study simply shows a correlation between high BPA levels and obesity in children. No definite causal link has been established.
BPA is a form of synthetic estrogen. It has been restricted for use in some children’s products, including bottles for babies and sippy cups for toddlers.
The FDA has not banned its use in other containers since the chemical is not known to have any deleterious effect on adults.
Previous studies have hinted at a correlation between obesity in adults and BPA levels.
