Children who have higher levels of Bisphenol A (BPA), a chemical previously used in many products for kids, like baby bottle and plastic toys, had a higher odds of obesity and adverse levels of body fat, according to a new study from University of Michigan researchers.
The U-M team studied the levels of BPA found in children’s urine and then measured body fat, waist circumference, and cardiovascular and diabetes risk factors, in a study published today in Pediatrics.
BPA was previously widely used in the manufacturing of polycarbonate and epoxy resins used in a variety of products for children, including baby bottles, protective coatings on metal food containers, plastic toys, and dental sealants.
“Studies in adults had shown an association between high BPA levels and obesity, diabetes and cardiovascular disease, but little was known about its effects in children,” says Donna Eng, M.D., lead author of the study and recent graduate of the Pediatric Endocrinology Fellowship at C.S. Mott Children’s Hospital.
The study found that higher odds of obesity, defined as a BMI above the 95th percentile on Centers for Disease Control and Prevention growth curves, was associated with higher levels of urinary BPA. Researchers also found that children with higher BPA levels also were more likely to have an abnormal waist circumference-to-height ratio.
