Aim: to assess sleep quality in patients with type 2 diabetes (T2D) experiencing low perceived psychological stress and high perceived psychological stress.

Methods: Perceived stress level and sleep quality were assessed in 154 patients with T2D (58 men, 96 women, age 58.7±11.8 years), using Perceived Stress Scale (a higher score denotes a higher level of perceived stress) and Pittsburgh Sleep Quality Index (a higher score denotes worse sleep quality).

Results: Patients with T2D with high stress level had worse subjective sleep quality (P=0.027), higher use of sleeping medication (P=0.023), daytime dysfunction (P<0.001) than those with low stress level. No significant differences were found in sleep latency, sleep duration, habitual sleep efficiency and sleep disturbances as well as in T2D duration, body mass index and glycated haemoglobin (HbA1c) level between patients experiencing low and high perceived stress. Perceived stress level in patients with T2D correlated with subjective sleep quality (r=0.260, P=0.002), sleep duration (r=0.228, P=0.005), use of sleep medication (r=0.245, P=0.004), daytime dysfunction (r=0.326, P<0.001).In conclusion, patients with type 2 diabetes experiencing high perceived psychological stress level have worse subjective sleep quality, higher use of sleeping medication, daytime dysfunction than patients experiencing low perceived stress level. Perceived stress level in patients with type 2 diabetes is related to subjective sleep quality, sleep duration, use of sleep medication, daytime dysfunction.
