摘要：Purpose: To evaluate the impact of several factors on the patient’s perception on quality of life in a group of patients with type 2 diabetes mellitus (T2DM). Patients and methods: In this cross-sectional study, 198 patients with T2DM were enrolled according to a consecutive-case population-based study design. In all participants, the perception on the quality of life was measured using the quality of life index – diabetes version III proposed by Ferrans and Powers. We evaluated the impact of several anthropometric and diabetes-related (ie, diabetes history and quality of glycemic control) factors on the patient’s perception on the quality of life. Results: The presence of diabetes complications was associated with a decreased quality of life: retinopathy (1 vs 5 points; P <0.001), chronic kidney disease (-1 vs 5 points; P <0.001), and neuropathy (-1 vs 5 points; P <0.001). A significant reverse correlation was found between the patient’s quality of life and depression’s severity (Spearman’s r =-0.345; P <0.001) and body mass index (Spearman’s r =-0.158; P =0.026). A positive association between the quality of life and the quality of diabetes-related self-care activities was found (Spearman’s r =0.338; P <0.001). No significant association was found between the patient’s quality of life and the quality of glycemic control, diabetes duration, age, gender, or smoking status. Conclusion: To improve the patient’s quality of life, special care should be given to the modifiable diabetes-related factors: the prevention and treatment of diabetes complications, treatment of depression, and weight loss in obese and overweight patients.
