Background. Limited epidemiological data are available on predictors of new-onset kidney disease. Methods. In this longitudinal cohort study, 17 375 apparently healthy volunteers of the general Viennese population (46.4% women, age range 20â84 years, men 20â89 years) performed a baseline examination at some time within the study period (1990â2005) and completed a median of two follow-up examinations [interquartile range (IQR) 1 to 4]; the median follow-up period was 7 years (IQR 4 to 11). The outcome of interest was the development of kidney disease, defined as a decrease of the glomerular filtration rate (GFR) Results. The following parameters [odds ratios (OR) with 95% confidence intervals] predicted new-onset kidney disease: Age (increase by 5 years), OR = 1.36 (1.34â1.40); National Kidney Foundation-chronic kidney disease (NKF-CKD) stage 1 with proteinuria (), OR = 1.39 (1.10â1.75); NKF-CKD stage 1 with proteinuria (â¥), OR = 2.07 (1.11â3.87); NKF-CKD stage 2 with proteinuria (), OR = 2.71 (2.10â3.51); NKF-CKD stage 2 with proteinuria (â¥), OR = 3.80 (2.29â6.31); body mass index, OR = 1.04 (1.02â1.06); current-smoker, OR = 1.20 (1.01â1.43); performing no sports, OR = 1.57 (1.27â1.95); uric acid (increase by 2 mg/dl), OR = 1.69 (1.59â1.80); HDL-cholesterol (decrease by 10 mg/dl), OR = 1.12 (1.07â1.17); hypertension stage 1, OR = 1.35 (1.08â1.67); hypertension stage 2, OR = 2.01 (1.62â2.51); diabetes mellitus, OR = 1.44 (1.07â1.93). Conclusions. Cardiovascular risk factors as well as NKF-CKD stages 1 and 2 and proteinuria, the more the higher and an entirely novel finding, performing no sports, predicted new-onset kidney disease.
