Face to face interview was used to obtain participant’s information by using a validated questionnaire. The value of fasting blood sugar or random blood sugar and HbA1c were also obtained. Results: Among 380 type 2 diabetes mellitus, 76.8% had poor sleep quality. No significant correlation was found between age, body-mass index, duration of diabetes, and duration of comorbid disease.
