Eating Disorders and Sleep Disturbance as Determinants of Metabolic Control in Adolescents with Type 1 Diabetes.

This cross-sectional study examined the effect of sleep disturbance and eating disorders on metabolic control in adolescents with Type 1 Diabetes. The study was conducted with adolescents with T1DM treated at a university hospital in Turkey between October 2023 and January 2024. The study sample consisted of 120 adolescents with T1DM between the ages of 10-18. Data were collected online using the Adolescent Information Form, Dutch Eating Behavior Questionnaire (DEBQ), and DSM-5 Sleep Disorder Scale (SDS). Mean, percentage, and regression analyses were used to analyze the data. Ethics committee, institutional permission and written permission from the adolescents with Type 1 Diabetes and their parents were obtained for the study. In the current study, sleep disturbance and eating disorders explained 38.5% and 40.2% of HbA1c, respectively, and were found to have a significant effect (respectively: F = 73.737, p ≤ .001; F = 19.353, p ≤ .001). This study provides evidence that eating disorders and sleep disturbance explain approximately half of HbA1c. The results of the study revealed that sleep disturbance and eating disorders were significant predictors of metabolic control in adolescents with type 1 diabetes.
