Relationship between symptoms observed in patients with type 2 diabetes and the sleep quality

Aim: The aim of this study was to investigate the relationship between disease-related symptoms observed in patients with type 2 diabetes and the sleep quality.Material and Methods: This was a correlative descriptive study conducted between July 2015 and July 2016. The sample of the study was formed by 256 patients selected via the non-probability randomized sampling method and calculated according to the sample-size with the known universe formula. The DSC-R and the PSQI were used for the data collection.Results: The mean total score obtained from the DSC-R was 2.12±1.05. 86.3% of the patients were determined to have poor sleep quality. The mean total score obtained from the PSQI was 10.71±4.08. A statistically significantly positive correlation was observed between all sub-dimensions of DSC-R and the PSQI total. A negative correlation was determined between diabetes-related symptoms and the sleep quality, and accordingly, the quality of sleep impaired as the incidence of diabetes-related symptoms became higher. Additionally, despite hyperglycemia-related symptoms having been observed more frequently, the cardiological symptoms affected the sleep quality at a higher extent.Conclusions: It was determined that a negative relationship between sleep quality and symptoms of diabetes and increased symptoms of diabetes decreased in sleep quality.
