Abstract
Introduction: Chronic kidney disease (CKD) is closely linked to high blood pressure (HBP) which is its leading cause in developing countries. Hypertension affect 1.2 billion people worldwide. However, a significant portion of individuals with HBP are undiagnosed and their kidney function is even less known. The objective of this study was to determine the prevalence and associated factors of chronic kidney disease among three sub-groups of blood pressure status (normotensive, diagnosed hypertension and undiagnosed hypertension) individuals.
Patients and methods: We conducted a cross-sectional study in the general population of three northern regions in Senegal using a two-level cluster sampling method. The sample was constituted with a precision of 5% and a power of 80%, with an additional 10% attrition margin. Individuals aged 18 - 80 years were included in the study after consent. Pregnant women, hospitalized persons within the past three months, patients with general or urinary symptoms within the past seven days and individuals undergoing renal replacement therapy were excluded. Investigators collected Clinical and biological data at participants' homes using a modified version of the WHO's STEPwise questionnaire. Samples were collected for biochemical analysis (serum creatinine, lipid profile and blood sugar). Estimated GFR was calculated using the CKD-EPI 2021 formula.
Results: A total of 2441 participants were included in the study with a mean age of 45.4 +/- 16.0 years and a sex ratio M/F of 0.4. The Overall prevalence of HBP and CKD were respectively 52.0% and 17.8%. Three out of every five hypertensive patients were undiagnosed. Chronic kidney disease was more frequent among known hypertensive patients (30.5%) compared to individuals with undiagnosed hypertension (19.1%) and normotensive individuals (10.9%). Multivariate analysis showed that CKD was associated with older age and female sex.
Conclusion: Undiagnosed hypertension is common among populations in northern Senegal. A high prevalence of CKD was found among both diagnosed and undiagnosed individuals with hypertension. Extending strategies for early detection and management in the general population could help prevent or reduce morbidity and mortality associated with CKD.
期刊介绍：
This journal comprises both clinical and basic studies at the interface of nephrology, hypertension and cardiovascular research. The topics to be covered include the structural organization and biochemistry of the normal and diseased kidney, the molecular biology of transporters, the physiology and pathophysiology of glomerular filtration and tubular transport, endothelial and vascular smooth muscle cell function and blood pressure control, as well as water, electrolyte and mineral metabolism. Also discussed are the (patho)physiology and (patho) biochemistry of renal hormones, the molecular biology, genetics and clinical course of renal disease and hypertension, the renal elimination, action and clinical use of drugs, as well as dialysis and transplantation. Featuring peer-reviewed original papers, editorials translating basic science into patient-oriented research and disease, in depth reviews, and regular special topic sections, ''Kidney & Blood Pressure Research'' is an important source of information for researchers in nephrology and cardiovascular medicine.
