Highly increased risk of type 2 diabetes in patients with binge eating disorder and bulimia nervosa

FRIDAY, Aug. 21, 2015 (HealthDay News) 

-- Binge eating disorder (BED) and bulimia nervosa (BN) are associated with increased incidence and prevalence of type 2 diabetes (T2D), according to a study published in the September issue of the International Journal of Eating Disorders.

Anu Raevuori, M.D., Ph.D., from the University of Helsinki, and colleagues examined the prevalence and incidence of T2D in a 2,342 patients treated at the Eating Disorder Unit of Helsinki University versus 9,368 matched general population controls over 16 years. T2D incidence was examined over three stages: before entering treatment for an eating disorder; after entering treatment until the end of the study; and combined any time before, during, and after treatment.

The researchers found that the risk of T2D was increased in patients versus controls (odds ratio, 6.6) before entering treatment for eating disorders. The lifetime prevalence was 5.2 percent among patients at the end of the study period, compared with 1.7 percent among controls; prevalence was significantly higher in male patients versus female patients. By the end of the study, every third patient treated for BED had T2D (odds ratio, 12.9) and 4.4 percent of those with BN had T2D (odds ratio, 2.4)

Such is the consequence of having a misunderstood, yet life-threatening sickness that affects hundreds of thousands of Canadians – most of them women and girls.

An estimated 1,500 Canadians die every year as a result of an eating disorder. Yet, in the five years it takes to complete a psychiatry residency training program, residents typically receive only three hours of instruction on eating disorders, according to Toronto psychiatrist Dr. Blake Woodside.

As noted in a report on eating disorders last year by a parliamentary standing committee on the status of women, medical and psychiatry students receive inadequate training on the subject. At present, of the nearly 4,800 licensed psychiatrists in Canada, slightly more than a dozen specialize in eating disorders.
