The Effect of a Gluten-Free Diet on Sleep Disturbances in Children with Celiac Disease

Purpose: Sleep disturbances are common in patients with celiac disease (CD), but their response to a gluten-free diet (GFD) treatment remains scarce. This study investigated the alteration in sleep disturbances within 6 months of starting a GFD in children with CD. Patients and Methods: A total of 103 children initially diagnosed with CD, with no psychiatric diagnosis and not receiving psychotropic medication, were included in this study. Sociodemographic data were collected, and the Children's Sleep Habits Questionnaire (CSHQ) was completed both before and after six months of initiating a GFD. Results: Overall, the total average CSHQ score was 46; after starting the GFD, this decreased to 40, which was under the clinically significant cutoff level for sleep disturbance (p < 0.001). A total of 74 patients (71.8%) had a CSHQ score above the clinically significant cutoff before treatment, which decreased to 40 patients (38.8%) six months after GFD (p < 0.001). A significant improvement was detected in all CSHQ subscale scores and in the total CSHQ score after starting the GFD (p < 0.001). Parasomnia and the total CSHQ score were higher in children who were diagnosed incidentally compared to symptomatic children but did not differ after GFD (p < 0.005). In 39 patients (37.8%), the total CSHQ score remained high 6 months after starting the GFD. Maternal and paternal ages were significantly higher in children whose scores remained high (p < 0.05). Conclusion: A significant improvement in sleep scores was detected after starting a GFD, regardless of initial age, sex, and symptom status. With a GFD, children may fall asleep more easily and sleep for longer with less interruptions. GFD may help to reduce sleep disturbances in CD, but future studies should investigate the certain conditions in patients who do not respond to a GFD.
