The prevalence of chronic kidney disease in a Flemish primary care morbidity register

摘要

SIR-Based on earlier research [1, 2], we know that the estimated glomerular filtration rate (eGFR) decreases with age, starting in the third decade, even in healthy, normoten-sive adults. The components of this decrease in eGFR that are due to normal ageing and those that are due to non-ageing-related damage, caused by diabetes, hypertension, atherosclerosis or glomerulonephritis, remain uncertain.In this study, the data from a large Flemish general practice-based morbidity registry, called Intego, were used to obtain a clear view of the prevalence of chronic kidney disease (CKD) in primary care patients aged 50 and older as well as the prevalence of severe CKD (eGFR <30 ml/ min)
