CDC estimates 1 in 7 American adults have chronic kidney disease

The number of Americans with chronic kidney disease is higher than previously estimated and affects 15% of the U.S. adult population, according to new data analyzed by the Centers for Disease Control and Prevention. One in seven American adults, or 30 million people, are estimated to have CKD. However, 96% of those with early kidney disease (stages 1 and 2) don’t even know they have CKD. And of those with severely reduced kidney function, (stage 4) but not on dialysis, 48%, are not aware of having the disease.
“30 million Americans are affected by chronic kidney disease and most do not even know they have it. Let these new statistics from CDC serve as a warning bell that a major public health challenge is right in front of our eyes and more must be done to address it,” said Kevin Longino, CEO, National Kidney Foundation and a kidney transplant patient. “Additional federal resources must be allocated towards increasing public awareness about the disease and advancing programs targeted towards prevention and early detection. Leaders in the health care industry also need to prioritize CKD for the costly, impactful disease that it is—the earlier we can diagnose someone with kidney disease the better their long-term outcomes.”
Other findings:
- Women are more likely than men to have CKD, (16% vs. 13%), but men are 64% more likely than women to progress to end-stage renal disease (ESRD), the stage when kidneys stop working and dialysis or a transplant is needed just to stay alive.
- An estimated 15% of Hispanics have CKD and Hispanics are 35% more likely than non-Hispanics to progress to ESRD.
- CKD is estimated to be more common in non-Hispanic blacks (18%) than in non-Hispanic whites (13%).
The study, which analyzed adults aged 18 years or older with CKD stages 1-5, used data from the 2011-2014 National Health and Nutrition Examination Survey and the CKD Epidemiology Collaboration (CKD-EPI) equation.
The higher estimate in the number of Americans affected by chronic kidney disease, versus statistics previously reported by the National Kidney Foundation, is due to several factors including differences in study time frames, methodologies and populations, as well as an aging population and increased prevalence of risk factors such as diabetes and hypertension, the NKF said.
