The association between diabetic complications and health-related quality of life in patients with type 2 diabetes: a cross-sectional study from Iran.

INTRODUCTION

This study aimed to investigate the health-related quality of life (HRQoL) of type 2 diabetic patients and its relationship with the complications of diabetes in Farashband County, Fars, Iran.

METHODS

Data of this cross-sectional study were collected by a researcher-made demographic questionnaire, EuroQol-5 Dimensions questionnaire (EQ-5D) and Visual Analog Scale (VAS) and also from patient records. Multivariate regression model was used to investigate the net effect of diabetes complications on HRQoL after controlling for other independent variables.

RESULTS

A total of 685 patients with a mean age of 58.36 and a disease duration of 7.64 years participated in the study. The mean EQ-5D and EQ-VAS scores of all patients were 0.64 and 56.53, respectively. The HRQoL dimensions in which the largest portions of the population had problems were Pain/Discomfort (77.23%) and Anxiety/Depression (63.50%). Among the studied diabetic patients, women, divorcees, and widows were more likely to report problems in all dimensions of HRQoL, and people without complications, people with university degrees, and employed people were more likely to report fewer problems in these dimensions (P < 0.05). After controlling for the effect of all independent variables in the multivariate regression model, a significant negative relationship was found between diabetes complications and EQ-5D: β =  - 0.149 (95% CI - 0.186, - 0.112) and EQ-VAS: β =  - 6.697 (95% CI - 9.947, - 3.747). This indicates that for each additional diabetic complication, 0.149 and 6.697 units of EQ-5D Index and EQ-VAS were reduced, respectively.

CONCLUSION

This study indicated that type 2 diabetic patients in the studied region, especially those with complications, suffer from poor HRQoL. Therefore, more attention should be paid to the main determinants of HRQoL when adopting policies for diabetes management in order to ultimately improve the HRQoL of these patients.
