Objective: Poor sleep quality is a prevalent health problem among patients with diabetes. Metabolic syndrome (MetS) is common in type 2 diabetic patients, and associated with morbidity and mortality. We aimed to investigate sleep quality among type 2 diabetes patients according to their metabolic syndrome status.

Participants: This was an analysis of data collected from 189 adult type 2 diabetic patients.

Methods: The patients were divided into two groups (metabolic and non-metabolic) based on the presence of MetS. Anthropometric measurements, blood pressure and serum glucose, lipid levels were collected. The Pittsburgh Sleep Quality Index (PSQI) was calculated for all patients .

Results: There was no significant difference in subjective sleep quality scores between the two groups (P > 0.05). However, there was a significant difference in sleep latency scores between the two groups; the scores of patients with MetS were lower than those of patients without MetS (P = 0.010, P < 0.05). Sleep quality was low in 57.1% (n = 108) of the patients with diabetes.

Conclusions: Poor sleep is common among diabetic patients, but in this study metabolic syndrome existence was not associated with sleep quality in type 2 diabetic patients.
