As part of their treatment, patients with type 1 diabetes mellitus (DM) have to be very careful with what they eat and with their insulin doses. Therefore, the risk of eating disorders increases in this patient group. In this study, we aimed to determine the disordered eating behaviors of patients with type 1 DM and to evaluate the sociodemographic characteristics, diabetes care behaviors, and quality-of-life scale results that these behaviors may be related to.

The sociodemographic characteristics and diabetes treatment data of 191 patients aged 9–18 years with type 1 DM were analyzed. The Pediatric Quality of Life Inventory (PedsQL), the PedsQL 3.0 Diabetes Module, and the Diabetes Eating Problem Survey-Revised (DEPS-R) were applied.

The median DEPS-R score of the patients was 18 (19.00), and 44.5 % had a DEPS-R score above 20. A significant correlation was found between age, duration of diabetes, frequency of blood glucose measurement, hemoglobin A_1c (HbA_1c) level, body mass index standard deviation score (BMI-SDS), and DEPS-R score. There was no significant difference between girls and boys. Patients with a high DEPS-R score had low scores on the PedsQL and on the PedsQL 3.0 Diabetes Module.

The DEPS-R scale is a diabetes-specific, easy-to-use, and effective method for screening patients with type 1 DM for disordered eating behaviors. It can help prevent the progression of disordered eating behaviors to clinical eating disorders in patients with type 1 DM. It would be beneficial to use this scale as a routine screening, especially in clinics where access to a psychologist is not possible.
