Sleep quality in diabetic patients in Iran: A review

Objective (s): Diabetes is the most common metabolic syndrome that can cause debilitating complications due to its high prevalence. The aim of this study was to review the sleep quality of people with diabetes in Iran. Methods: This was a narrative review. Persian and English articles until May 2020 were reviewed using the ‘glycemic, diabetes, quality of sleep, metabolic syndrome, Iran’, keywords in databases such as: ProQuest, science direct, scopus, google scholar, Pubmed, Magiran, SID, and IranMedex. Results: In total 27 articles were reviewed. The articles were classified into three categories: the sleep quality (11 articles), interventions to improve the sleep quality (10 articles) and the effect of sleep quality on metabolic indicators (6 articles). The results showed that 15% of the articles reported that the sleep quality of diabetic patients was favorable, 35% of the articles reported the quality of sleep as unfavorable and 50% of the quality of sleep as moderate. Conclusion: Due to the low level of sleep quality of diabetic patients, the breadth of sleep and its quality among diabetes patients seems an important issue that needs appropriate interventions.
