Health-related quality of life and its determinants among patients with diabetes mellitus: a multicentre cross-sectional study in Northwest Ethiopia

Objectives This study assessed the health-related quality of life (HRQoL) and its determinants in patients with diabetes. Design and setting An institutional-based multicentre prospective cross-sectional study design was conducted in diabetes follow-up clinics of selected hospitals in Northwest Ethiopia from April to July 2022. Participants All eligible adult patients with diabetes at the selected facilities. Main outcome measures HRQoL was measured using EuroQol 5-dimensions 5-levels (EQ-5D-5L) and the EuroQol-Visual Analogue Scales (EQ-VAS) instruments. A lower EQ-5D-5L utility mean score for each dimension and/or an overall lower utility score of EQ-5D-5L and EQ-VAS scores are intended to show poor HRQoL. Linear regression analysis was used to identify the association of HRQoL and other variables. Results Out of the 422 samples approached, 402 (95.3%) participated in the study. Most of the participants (>85%) reported having moderate-to-severe problems in all five EQ dimensions. The overall EQ-5D-5L utility and EQ-VAS scores were 0.56 (0.11) and 56.7 (+/- 10.1), respectively. A higher body mass index (BMI) (p < 0.001), a higher number of medications (p = 0.037), a high level of blood glucose (p < 0.001), the presence of comorbidities and/or complications (p = 0.031), hypoglycaemia (p = 0.043) and taking insulin (p < 0.001) were associated with worsened HRQoL, whereas practicing self-monitoring of blood glucose (p = 0.002) and taking aspirin (p = 0.008) had a significant association with increased HRQoL. Conclusion This study concluded that the HRQoL of patients was compromised in all five measuring dimensions. The EQ-5D-5L utility and EQ-VAS scores were far lower than other findings. Clinical and medication-related variables, such as a higher BMI, a higher number of medications, the presence of comorbidities and/or complications, hypoglycaemia and insulin use were associated with poor HRQoL in patients with diabetes. As a result, interventions should be individualised and focused on determinant factors.

Automated summary

This study assessed the health-related quality of life (HRQoL) and its determinants in patients with diabetes. The results showed that HRQoL was compromised in all five measuring dimensions for patients with diabetes. Variables such as body mass index (BMI), number of medications, blood glucose level, comorbidities and/or complications, hypoglycaemia, and insulin use were associated with poor HRQoL.
