PurposeTo 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 MethodsIn 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.ResultsThe 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.ConclusionTo 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.
