Prevalence of Chronic Kidney Disease among the High Risk Population in South-Western Ghana; A Cross Sectional Study

Abstract

Background: Chronic Kidney Disease (CKD) is a major global health problem. CKD is one of the most common complications of diabetes mellitus and hypertension and carries a risk of cardiovascular morbidity and mortality and progression to end-stage kidney disease. Objectives: This study sought to use the 2012 Kidney Disease Improving Global Outcomes (KDIGO) definitions to establish the prevalence and risk factors for CKD among a high risk population in the Sekondi-Takoradi metropolis. Design: Cross sectional study. Setting: Effia-Nkwanta regional and the Takoradi Government hospitals in South Western Ghana. Patients: Two hundred eight consecutive adults with diabetes, hypertension or both. Measurements: Serum creatinine and urine albumin-creatinine ratio respectively. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) was used to estimate glomerular filtration rate (GFR). Methods: CKD was classified according to KDIGO. Results: The prevalence of CKD was 30 %: 27 % in patients with diabetes, 22 % in patients with hypertension only and 74 % in patients with both diabetes and hypertension. GFR category G3a CKD was most prevalent stage (9 %). Albuminuria was highest among people with diabetes (39 %). Limitations: A convenience sample of patients attending clinics. Conclusion: CKD was prevalent in these high-risk patients.
