Abstract
In an examination of Navajo elderly inpatients and outpatients, high rates of protein undernutrition (despite normal caloric stores) were found to be prevalent. The protein malnutrition was present in each of several measures used, covering structural as well as visceral protein. It was more common in males, inpatients, and the aged elderly, but excess rates of undernutrition were found in all groups examined. These rates were higher than those in any comparable group reported to date. With multiple regression analysis, length of stay in the hospital is shown to be related to this undernutrition among inpatients studied.
