| ==Overview==
| |
| The incidence and prevalence of chronic renal failure varies enormously depending on the level of affluence of the country. Developed countries have a higher incident rate of treated end-stage renal failure, whereas the emerging countries have very low incident rates. There are currently about one million patients undergoing [[dialysis]] worldwide, with an incidence of 0.25 million patients each year.

| ==Epidemiology of CKD in United States==

| In 2003, the Third National Health Survey reported a prevalence of CKD in the general population (age 20 or older) of 11% (19.2 million). When divided by CKD stage, 3.3% of participants had stage 1, 3.0% had stage 2, 4.3% had stage 3, 0.2% had stage 4, and 0.2% had stage 5, or ESRD. <ref name="pmid12500213">{{cite journal| author=Coresh J, Astor BC, Greene T, Eknoyan G, Levey AS| title=Prevalence of chronic kidney disease and decreased kidney function in the adult US population: Third National Health and Nutrition Examination Survey. | journal=Am J Kidney Dis | year= 2003 | volume= 41 | issue= 1 | pages= 1-12 | pmid=12500213 | doi=10.1053/ajkd.2003.50007 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=12500213 }} </ref> The study also showed that beyond the classical risk factors notably diabetes and hypertension, age was a separate correlate with CKD prevalence with 11% of people older than 65 years of age having stage 3 or worse CKD in the absence of both diabetes and hypertension. Overall, 26% of the general population above 65 years of age has some form of kidney disease manifested by an eGFR <60 mL/min/1.73 m<sup>2</sup>. Ethnicity was found to be related to CKD and ESRD prevalence. ESRD was slightly more prevalent in non-Hispanic blacks than in non-Hispanic whites. In contrast, less severe stages of CKD were more common among whites, and least common among Mexican Americans.<ref name="pmid12500213">{{cite journal| author=Coresh J, Astor BC, Greene T, Eknoyan G, Levey AS| title=Prevalence of chronic kidney disease and decreased kidney function in the adult US population: Third National Health and Nutrition Examination Survey. | journal=Am J Kidney Dis | year= 2003 | volume= 41 | issue= 1 | pages= 1-12 | pmid=12500213| doi=10.1053/ajkd.2003.50007 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=12500213 }}
