New research from the West Virginia University School of Medicine has confirmed other research finding that Bisphenol A (BPA) – found among various plastics and resins in consumer goods – may lead or contribute to type 2 diabetes.
The researchers examined 3,516 people using the National Health and Nutritional Examination Survey of 2003-2008. The researchers compared the urinary BPA levels with fasting glucose levels to determine if there was a relationship between higher BPA concentration in the body and a prediabetic condition.
The researchers used the range for fasting glucose of 100-125 mg/dL and two-hour glucose levels of 140-199 mg/dL or a glycated hemoglobin (A1C) value of 5.7-6.4 % as the standard for a prediabetic condition. A normal A1C range is between 4% and 6%, and the lower the level, the better.
The researchers found that those subjects with BPA levels in the highest third (tertile) range of BPA concentration in the urine had an average of 34% increased incidence of prediabetic condition in terms of their glucose or A1C levels.
The researchers eliminated other possible known factors in diabetes such as weight, blood pressure, cholesterol levels, and alcohol consumption.
