Bingeing Boosts Diabetes Risk

In a cohort study of about 4,300 girls, those who binged frequently — without "purging," or using laxatives or vomiting after a big meal — had nearly a four-fold increased risk of developing type 2 diabetes, even after controlling for body mass index (OR 3.93, 95% CI 1.27 to 12.13), Alison Field, ScD, of Boston Children’s Hospital, and colleagues, reported at the Obesity Week meeting. In total, the study included 4,323 female patients, who had a mean age of 15 and a mean BMI of 20.93; only about 13% of girls were overweight and only 4% were obese. There were 49 cases of diabetes that developed during follow-up. The overall prevalence of binge eating was low, with only 1.77% of girls binge eating weekly, 1.36% having a diagnosed binge eating disorder, and 4% meeting other characteristics of very minor binge eating. Overall, the researchers found that girls who binged frequently were significantly more likely to develop type 2 diabetes during follow-up, even after controlling for BMI (OR 3.93, 95% CI 1.27 to 12.13).  Field AE, et al "Independent of BMI, female binge eaters are more likely to develop diabetes" Obesity Week 2013; Abstract T-9-OR.
