Background: This study aims to evaluate the sleep quality in patients with type 2 diabetes mellitus (T2DM), and to assess the relevance of other factors to sleep quality.

Methods: A cross-sectional study was carried out at the National Center for Diabetes, Endocrinology and Genetics (NCDEG) in Amman, Jordan, during the period from October 1, 2015 to December 31, 2015. A total of 1,211 (540 male and 671 female) patients with T2DM were recruited. Data were collected using the Pittsburgh sleep quality index (PSQI) to assess the sleep quality with a cutoff point of PSQI ? 8. Participants demographic background data were also recorded. Statistical analysis was conducted using SPSS version 22.

Results: The mean age of our patients was 58.8 9.74 years. Mean body mass index (BMI) was 32.67 6.1 kg/m2, and mean duration of diabetes was 10.3 7.38 years. The mean PSQI score was 10.2 3.10. In the present study, poor sleep quality was reported in 81% of participants. Multivariate logistic regression analysis revealed that poor sleep quality was significantly associated with high HbA1c, female gender, smoking, unemployment, and insulin use. The study showed that subjective sleep quality and quantity, night sleep disturbance, and daytime dysfunction were risk factors for poor glycemic control.

Conclusions: In our series, patients with T2DM (81%) have poor sleep quality. Females, smokers, unemployed individuals, insulin users and patients with uncontrolled diabetes seem to be significantly at higher risk of poor sleep quality.
