No clear connection between BPA and type 2 diabetes says report
There is no clear link between bisphenol A exposure and the onset of type 2 diabetes according to a study published in the Annals of Internal Medicine. The Chinese study undertaken by scientists at the Shanghai Jiao-Tong University School of Medicine comprised 3423 local residents aged 40 years or older. Researchers measured the amount of BPA found in the participants’ urine in order to determine whether there was a ‘dose-response’ relationship. Reuters reported that one-quarter with the highest BPA levels did have a higher risk of developing diabetes than those in the quarter with the lowest levels. However, they did not find that the risk of diabetes climbed as BPA exposure did so they couldn’t conclude that there was a BPA-diabetes connection. Limitations outlined in the way the study was carried out include that many patients in the study already had diabetes and so their treatment might have obscured the results. Dietary variables were also not measures. China has already banned the use of BPA in the manufacture of babies’ bottles.
