Abstract
PURPOSE: To examine the relationship between the presence and severity of retinopathy in women with diabetes mellitus and sleep quality assessed using Pittsburgh Sleep Quality Index (PSQI). METHODS: Among 90 female patients with type 2 diabetes, 30 patients without retinopathy were classified into Group 1, 30 patients with nonproliferative diabetic retinopathy as Group 2, and 30 patients with proliferative diabetic retinopathy as Group 3. People who had a known sleep problem, had a history of using medication other than sleeping pills that would affect sleep, had lower or upper respiratory tract disease, had history of previous surgery, or were unable to answer the survey questions appropriately were excluded from the study. RESULTS: The mean age was 52.6 ± 6.18 years in Group 1, 55.15 ± 8.15 years in Group 2, and 60.35 ± 5.93 years in Group 3. While no statistical difference was observed between Groups 1 and 2 (P = 0.27), a statistical difference was observed between both Groups 1 and 3 (P = 0.01) and Groups 2 and 3 (P = 0.02). PSQI scores were found to be 5.10 ± 1.07 in Group 1, 7.30 ± 2.34 in Group 2, and 6.70 ± 1.21 in Group 3. In terms of these scores, there was a statistical difference between Group 1 and both Group 2 (P = 0.01) and Group 3 (P = 0.01), while no difference was observed between Groups 2 and 3 (P = 0.31). CONCLUSION: Although the presence of retinopathy significantly impairs sleep quality in diabeticwomen, no relationship was found between the severity of retinopathy and impaired sleep quality.
