Introduction: Sleep is essential for the proper functioning and the well-being of the body. Poor sleep quality has many negative effects on the patient health. The aim of our study was to determine the prevalence of sleep disorders in patients with type 2 diabetes and to identify the associated factors.

Methods: It is a cross-sectional study including 51 patients and conducted in the nutrition department A of the institute of nutrition of Tunis. The patients were enrolled in April 2022. Sleep quality were evaluated by Pittsburgh sleep quality index (PSQI). Poor sleep quality was defined by a score ≥5.

Results: The mean age of the patients was 59.1±9.51 years. The mean body mass index (BMI) was 27.83±5.5 kg/m² and the mean duration of diabetes was 12.2±10.31 years. The mean PSQI score was 7.4±4.03. Poor sleep quality was reported in 72.5% of cases. More than the half of these patients were women (52.9%). Only fasting plasma glucose (FPG) was significantly associated with poor sleep quality (P=0.001) with a positive correlation between FPG and PSQI score; an increase of 1 g/l caused a 2 points increase of the score. Age, sex, medical history, BMI, duration of diabetes and type of antidiabetic treatment were not associated with poor sleep quality.

Conclusion: Uncontrolled diabetes is a risk factor for sleep disorders. Similarly, poor sleep quality negatively affects diabetes control. Rigorous management is needed to break this vicious circle.
