Association between metabolic parameters and glomerular hyperfiltration in a representative Korean population without chronic kidney disease

AimsTo investigate associations of glomerular hyperfiltration with other metabolic factors in a nationally representative dataset.MethodsWe analyzed cross-sectional data from 15,918 subjects with estimated glomerular filtration rate (eGFR) >60 ml/min/1.73 m2 and urine albumin creation ratio (ACR) ResultsPrevalence of hyperfiltration was 5.2% and that among normal, prediabetic, and diabetic subjects was 4.9%, 5.6%, and 7.3%, respectively, after adjusting for age, sex, and body weight (p for trend = 0.008). In a multiple logistic regression analysis, hyperfiltration was associated with a body mass index ≥30 kg/m2 [odds ratio (OR) = 3.461, pConclusionsIn a general Korean population, both hyperfiltration and ACR were associated with similar metabolic parameters, and hyperfiltration correlated independently with a high ACR. Longitudinal studies are needed to further explore risks of hyperfiltration and microalbuminuria.
