Methods for determining healthy body weight in end stage renal disease.

摘要

Several formulas for calculating desirable body weight are used in chronic kidney failure patients. Ideal body weight (IBW) derived from Metropolitan Life Insurance tables has been available since the 1950s. The Hamwi formula was proposed in the 1960s as a simple tool for quickly estimating desirable body weight, especially in people with diabetes. Since the 1970s, National Health and Nutrition Evaluation Surveys I, II, and III have provided an in-depth evaluation of the average body weights of Americans. These standard body weights (SBW) are often interpreted to be normal and healthy weight goals. Body mass index (BMI) has also been studied for decades and is used internationally as the standard for determining healthy weight, especially in relationship to obesity. These 4 methods are discussed and compared along with a brief review of the history of using the adjusted body weight (ABW) formulas, followed by recommendations for clinical practice.
