Comparison of frequency of depression and sleep quality in patients with Type 2 Diabetes mellitus with controls

Abstract

Diabetes mellitus with its high prevalence and related hygienic problems is one of the most important worldwide burdens that can also cause mental and psychological side effects. The disease complications, chronic progress, treatment costs and social problems are among the issues that can affect the patients’ cognitive function and cause depression and sleep disorders. Failure to diagnose and treatment of such issues causes a poor prognosis and increases the risk of death. High prevalence of sleep disorders in diabetic adults and its association with depression and glucose metabolism encouraged us to conduct a study to compare the frequency of depression and sleep disorders in type-2 diabetic patients with non-diabetics. Methodology In a prospective case-control study design, considering the inclusion and exclusion criteria, 64 diabetic patients from 22 Bahman Hospital and 86 non-diabetic individuals as the matched group, were enrolled in the study during the years 2013 to 2014. To gather the data, Pittsburg sleep quality index and Hamilton depression rating scale was used. Results Sleep quality disorders and depression are more common in diabetic patients. In diabetic patients, percentage of depression and sleep quality disorders was 78.1, 68, and in non-diabetics, it was 50% and 36%, respectively. This study showed significant relationship between sleep quality disorders and depression between the two groups of participants. No significant relationship was found regarding control blood sugar, type of treatment and the amount of time a person is exposed to the disease and incidence of depression and sleeping problems. Conclusion Regarding the high prevalence of depression and sleep disorders in diabetic patients, it is necessary to diagnose depression and sleep disorders.
