Abstract
Background: Sleep is one of the most important physiologic cycles. Nearly every metabolic disorder, especially diabetes mellitus, can affect the quality and quantity of sleep. The aim of this study was to investigate the relationship between the quality of sleep and diabetes, using the Pittsburgh sleep quality index questionnaire on patients among the central area of Saudi Arabia. Methods: cross sectional study conducted among 188 patients with diabetes mellitus from the central area of Saudi Arabia, during the period from 1 January to 31 May, 2018. We used a predesigned questionnaire to collect the data from the sampled population. We used the Arabic Pittsburg Sleep Quality Index (A-PSQI). Distribution of the questionnaire included a hand-to-hand method and the creation of an online version of the questionnaire, which was published through the web and social media. Results: DM was more prevalent among females (66.5%) than males (33.5%). Comorbidities were hypertension in 20.7% of the studied patients, obesity (48.4%), anemia (8%) and chronic heart diseases (4.8%). There was more prevalence of poor sleep quality among diabetic patients (82.4%) and only 17.6% of them had good sleep quality. Poor sleep quality was more in females (69%) than males (31%). There was a statistically significant difference in sleep quality according to the age, educational level and occupation (P<0.05). Conclusion: According to the results of the study, it seemed important to improve the control of diabetes in order to improve the quality of sleep of diabetic patients.
