Prevalence of Sleep Disorders Among Patients With Type 2 Diabetes Mellitus in Makkah City: A Cross-Sectional Study

Background: Due to rising rates of morbidity and mortality associated with type 2 diabetes mellitus (T2DM), Saudi Arabia is ranked second in the Middle East and seventh overall among nations with the greatest incidence of diabetes mellitus (DM). Significant sleep abnormalities have been linked to difficulties in managing blood sugar levels, suggesting a link between sleep disorders and diabetes. This study aimed to find out how common sleep disturbances were among patients with T2DM in Makkah, Saudi Arabia. Methods: This descriptive cross-sectional study was conducted between June and August 2022 in Makkah City, Saudi Arabia. Patients with T2DM who visited primary healthcare facilities in Makkah during the study's duration were included in the study. To evaluate sleep quality, the Pittsburgh Sleep Quality Index in Arabic was employed. Patients who met the inclusion criteria were given an interview questionnaire to fill out. Results: In total, 355 patients with T2DM were enrolled in this study. The patients' median age was 49.24 years. Other than DM, a majority of them (58.9%) had chronic illnesses, with hypertension (64.5%) and cardiovascular disease (65.5%) as the most prevalent comorbidities. Only 22% of the patients had controlled diabetes. Of the individuals who had sleep disorders, 63.7% stated having poor sleep quality. Conclusion: Sleep problems are a common occurrence in patients with T2DM. Additionally, compared to people with other chronic disorders, people with endocrine diseases had poorer sleep quality. Hence, the duration of diabetes has an impact on sleep quality.
