Prevalence of Reduced Estimated Glomerular Filtration Rate Among the Oldest Old From 1988-1994 Through 2005-2010

Recent studies have shown that older adults with an estimated glomerular filtration rate (GFR) of less than 60 mL/min/1.73m 2 have a high prevalence of concurrent complications of chronic kidney disease (CKD) and increased risk for adverse outcomes including mortality, cardiovascular disease, and kidney failure. 1,2 A prior study demonstrated an increase in CKD prevalence between 1988-1994 and 1999-2004 for the general US population. 3 However, trends in CKD prevalence have not been reported for the oldest old (defined as ≥80 years).People aged 80 years or older often have complex medical, social, and psychological needs and substantial requirements for health care resources.This group represents an increasing challenge to the health care system.
