BPA Linked to Obesity Risk in Puberty-Age Girls

A study from the Kaiser Permanente Division of Research in Oakland, Calif., reported in the journal PLoS ONE that Bisphenol-A (BPA), a chemical used in plastics, is associated with a higher risk of obesity in girls ages 9 – 12. The authors wrote that girls in the beginning and middle of puberty whose BPA urine levels are above average have double the risk of being obese/overweight, compared to their counterparts with lower levels. The study — among the first specifically designed to examine the relationship between BPA and obesity in school-age children — was conducted in Shanghai as part of a larger national study of puberty and adolescent health.
