Summary:To investigate the sleep quality of patients with type 2 diabetes (T2D) and its impact on glycaemic control. Using a convenience sampling method, 220 patients with T2D were recruited. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep quality with threshold at PSQI ≥ 8. The glycosylated haemoglobin A1c (HbA1c) test was used to measure the glycaemic control with threshold at HbA1c < 7%. The PSQI score was 8.30 ± 4.12. The sleep disorder incidence rate was 47.1%. Patients with HbA1c ≥ 7% had significantly lower PSQI global and factor scores (p < 0.01) versus the control group. Sleep latency, sleep disturbance, and daytime dysfunction were the risk factors for poor glycaemic control. Patients with T2D have high sleep disorder rate negatively impacting glycaemic control. Health care providers should pay close attention to the sleep quality of T2D patients, and provide them with appropriate educational material.
