Abstract

The use of dietary supplements (DS) has been observed to be increasing among patients with diabetes. However, the effect of DS on health-related quality of life (HRQoL) is still an understudied area. This study aims to evaluate the prevalence of DS use among diabetic patients, their attitudes toward these supplements, and their effect on HRQoL. A cross-sectional study was conducted among diabetic patients attending an outpatient facility in Iraq. A validated survey instrument was used to collect data on DS use, attitudes, and HRQoL using EQ-5D measures. The study found that 73.8% of patients used DS, including omega-3 fatty acids, vitamin D, and probiotics. Users reported a positive attitude towards DS (P = 0.002). HRQoL measures showed issues in walking, personal care, daily activities, pain, and moderate depression. Thirty-six health statuses were reported, and the highest rated was health status 12222. A significant difference was noted between users and non-users of DS on the EQ-5D measure, where a positive effect of DS use was seen on diabetic patient health status (P < 0.001). It is necessary to implement complex interventions to improve patients’ health based on broad approaches to treatment.
