Management of Chronic Kidney Disease Stages 1–3

Slide: 6 of 29

Background: Public Health Impact

In the United States, an estimated 11.1 percent (22.4 million) of adults aged 20 or older have chronic kidney disease (CKD) stage 1, 2, or 3. NHANES (National Health and Nutrition Examination Survey) data from 1988–1994 and 1999–2004 suggest the prevalence of CKD is rising for every CKD stage. Estimates predict that more than 700,000 Americans will have end-stage renal disease by 2015.

The prevalence of CKD stages 1–3 among U.S. adults aged 40–50 years (6.7%) is more than double that of those aged 20–39 years (3.1%). The increase in prevalence is more dramatic with increased age: 17.6 percent among those aged 60–69 and 44.4 percent among adults aged 70 years or older. CKD prevalence is higher in women (12.6%) than in men (9.7%) and is similar in whites (11.6%) and blacks (11.2%).
