About

The goal of this research project is to improve the treatment of individuals living with both type 2 diabetes (T2D) and Binge Eating Disorder (BED). The research hypothesizes that BED treatment will not only improve BED symptoms but also improve T2D severity and associated cardiovascular risk factors. The research involves a multidisciplinary team, including experts in endocrinology, psychology, and eating disorders.

The main questions it aims to answer are:

• Does treatment for Binge Eating Disorder lead to improvements in BED symptoms?
• Does treatment for Binge Eating Disorder lead to improvements in T2D severity and associated cardiovascular risk factors?

Participants will undergo a comprehensive treatment program targeting both BED and T2D. This program will include psychotherapy sessions focusing on cognitive-behavioral techniques to address binge eating behavior.

Researchers will compare participants' outcomes before and after the treatment program to assess changes in BED symptoms, T2D severity, and associated cardiovascular risk factors.

Full description

This research project aims to address the treatment challenges faced by individuals living with both type 2 diabetes (T2D) and Binge Eating Disorder (BED). It is estimated that approximately 300,000 people in Denmark have T2D, while 40-50,000 adults suffer from BED. The prevalence of BED among patients with T2D is up to 20%, and individuals with T2D and BED often experience more somatic and psychological symptoms compared to those with T2D alone.

The primary objective of this project is to improve the treatment outcomes for patients with coexisting T2D and BED. To achieve this, the project has three specific aims:

1. Prevalence assessment: The project aims to identify the prevalence of BED within a cohort of approximately 4,000 patients diagnosed with T2D in the Region of Southern Denmark. This cohort is part of the DD2 cohort, managed by the Danish Center for Strategic Research in Type 2 Diabetes.
2. Treatment efficacy investigation: The project will conduct a Randomized Controlled Trial (RCT) involving 64 patients diagnosed with both T2D and BED. The trial will investigate the effects of BED treatment on various outcomes, including changes in BED symptoms, glycemic control, and associated cardiovascular risk factors.
3. Glucose sensor study: Patients will be assessed using continuous glucose monitoring sensors for a week before and after pre- and post-test visits at Odense University Hospital (OUH). This allows for detailed blood glucose profiles without finger pricking. Data on time in range, time below range, variability, and area under the curve will be extracted from the sensors. These data aim to provide insights into glycemic variability, complementing traditional HbA1c measurements and aiding in evaluating the intervention's effectiveness.

By addressing these aims, the project seeks to enhance the understanding of the prevalence of BED among individuals with T2D and evaluate the efficacy of BED treatment interventions in improving health outcomes for this patient population.

34 participants in 2 patient groups

BED treatment

Experimental group

Description:

The BED group therapy program consists of 11 sessions, followed by a 3-month follow-up session. Each 3-hour session accommodates eight patients and two psychologists. Treatment follows a manualized cognitive behavioral therapy approach, with patients receiving a complimentary manual at the start. Sessions are conducted both in-person and online using a blended care model, with about one-third delivered virtually.

Treatment:

Behavioral: BED treatment

Waitlist

Other group

Description:

The waitlist control group consists of participants who are placed on a waiting list to receive treatment. While participants in the treatment group immediately receive BED treatment (Arm 1), those in the waitlist control group do not receive active treatment initially. They remain on the waiting list for 6 months until the treatment group completes their intervention. At that point, participants in the waitlist control group also receive the same BED treatment, serving as a comparison group to evaluate the intervention's effectiveness.
