Health-related quality of life (HRQOL) of patients with type 2 diabetes mellitus and people without diabetes at a tertiary hospital in Port-Harcourt, Rivers State, Nigeria

Background: Health-related quality of life (HRQOL), a patient-sensitive outcome globally, has become the clinician’s primary goal of care. Evidence suggests that diabetes mellitus (DM) and its treatment/care impair patients’ HRQOL, which varies depending on patient population/factors. Diabetics’ HRQOL in South-South Nigeria is largely unknown. Objectives: This study assessed and compared the HRQOL of patients with type 2 diabetes attending the outpatient diabetic clinic at a tertiary hospital in Port-Harcourt, Rivers State, South-South Nigeria with age-/gender-matched nondiabetics living within the same environment. Materials and Methods: This descriptive cross-sectional comparative study recruited 200 respondents, respectively those with type 2 diabetes (cases) and nondiabetics (controls). Data were collected by using the World Health Organization Quality of Life–BREF (WHOQOL-BREF) questionnaire and analyzed by using descriptive and inferential statistics at P≤ 0.05 level of significance. Results: The two groups (200 each) had no significant differences (P = 0.35 - P = 0.98) in terms of their demographic variables. The diabetic group mean scores were significantly (P = 0.00) lower than that of the non-diabetics in terms of WHOQOL-BREF overall, health satisfaction, physical, psychological, and social domains. Diabetics with tertiary education (58%) had a significantly higher mean score (P = 0.012) in terms of overall WHOQOL-BREF than those with secondary and primary education (42%). Ninety-two patients (46%) with diabetes had comorbidities that increased significantly with age (P = 0.00) and expressed less satisfaction with their health (P = 0.04). Conclusion: Patients with diabetes had lower HRQOL scores than non-diabetics, implying the negative impact of diabetes and its treatment/care on their life. Diabetics’ HRQOL should be routinely evaluated and enhanced by empowering diabetic self-care activities that aid diabetes control and retard complications.
