Sleep disorders in Chronic diseases are prevalent. This study was aimed to compare sleep quality and disorders among patients with controled and uncontroled diabetes mellitus and relationship between metabolic controls of glucose and sleep.

Data were collected using Pittsburgh sleep quality index (PSQI) and DSM-IV-TR schedule and analyzed using chi-square, logestic regression and t-test.
Results: In the currentr study, sleep duration and quality were in significant linear corolation with HbA1c level, a key marker of glycemic control and in general, major sleeping disorders in uncontroled diabetes were dissomnia.
Conclusion: According to the importance rule of good glycemic control in type 2 diabetic mellitus patients, adjustment of related factors is important. Life style is one of the most important effective factor for care of diabetic patients. Sleep and rest are the most important components of human life, and for glysemic control. So, optimizing sleep duration and quality and identifying and treatment of sleep disorders should be considered as an intervention to improve glucose control in patients with type 2 diabetes.
