Abstract

SummaryObjectiveTo determine the prevalence of risk factors for cardiovascular disease (CVD) in first-degree relatives (FDRs) of patients with chronic kidney disease (CKD) in a sub-Saharan African population.MethodsThis was a cross-sectional survey of 460 subjects (230 FDRs of patients with CKD and 230 healthy controls). Anthropometrics and blood pressures were measured. Spot urine and fasting venous blood samples were obtained for biochemical analysis.ResultsThe prevalence of hypertension, diabetes mellitus, obesity and dyslipidaemia were significantly higher in FDRs of patients with CKD compared with the controls: 56 (24.3%) vs 29 (12.6%), p = 0.01; 20 (8.7%) vs 6 (2.6%), p = 0.01; 40 (17.4%) vs 24 (10.4%), p = 0.03 and 171 (74.3%) vs 138 (60.0%), p = 0.01, respectively. Hypertension (OR, 1.65), dyslipidaemia (OR, 1.72) and albuminuria (OR, 1.61) were independently associated with being a FDR of patients with CKD.ConclusionIn this sub-Saharan African population, risk factors for CVD were more prevalent in the FDRs of patients with CKD than in healthy controls.

Highlights

Hypertension (OR, 1.65), dyslipidaemia (OR, 1.72) and albuminuria (OR, 1.61) were independently associated with being a first-degree relatives (FDRs) of patients with chronic kidney disease (CKD). In this sub-Saharan African population, risk factors for cardiovascular disease (CVD) were more prevalent in the FDRs of patients with CKD than in healthy controls
Multiple logistic regression analysis was used to determine CVD risk factors that were independently associated with being a FDR of a patient with CKD
Hypertension (OR, 1.65), dyslipidaemia (OR, 1.72) and albuminuria (OR, 1.61) are CVD risk factors that were independently associated with being a FDR of a patient with CKD (Table 3)

Summary

Introduction

Objective: To determine the prevalence of risk factors for cardiovascular disease (CVD) in first-degree relatives (FDRs) of patients with chronic kidney disease (CKD) in a subSaharan African population. Results: The prevalence of hypertension, diabetes mellitus, obesity and dyslipidaemia were significantly higher in FDRs of patients with CKD compared with the controls: 56 (24.3%) vs 29 (12.6%), p = 0.01; 20 (8.7%) vs 6 (2.6%), p = 0.01; 40 (17.4%) vs 24 (10.4%), p = 0.03 and 171 (74.3%) vs 138 (60.0%), p = 0.01, respectively.
