Study Objectives: To investigate the relationship between blood sugar regulation, sleep quality, and dietary habits among individuals with type 1 diabetes.

Methods: 195 type 1 diabetic patients (110 women and 85 men) between the ages of 18 and 65 undergoing insulin treatment. Participant’s blood sugar levels (HbA1c), sleep quality (measured by the Pittsburgh Sleep Quality Index - PSQI), and dietary habits (measured by the Healthy Eating Index) were assessed. Statistical analysis was conducted to examine the relationship between PSQI scores, HbA1c levels, and Healthy Eating Index scores.

Results: A significant association was found between sleep quality and blood sugar regulation, as indicated by HbA1c levels. Participants with HbA1c levels greater than 7% tended to have poorer sleep quality compared to those with lower HbA1c levels. Conversely, participants with HbA1c levels of ≤7% demonstrated significantly better dietary habits, as reflected by higher Healthy Eating Index scores.

Conclusions: The study suggests a strong correlation between blood sugar regulation, sleep quality, and dietary habits in individuals with type 1 diabetes. Maintaining optimal blood sugar management, promoting good sleep hygiene, and adhering to a healthy diet are essential for managing type 1 diabetes effectively. Strategies to improve sleep quality and dietary habits may contribute to better blood sugar control and overall well-being in individuals with type 1 diabetes.
