Although norms are available for healthy subjects, it is preferable, when interpreting anthropometry in individual dialysis patients, to compare measurements with norms for the stable dialysis population. The purpose of this study was to develop these reference anthropometric norms for dialysis patients. Triceps skinfold (TSF), subscapular skinfold (SSF), and mid-upper arm circumference (MUAC) measurements were made in 925 patients with no major illness, who were being treated by chronic maintenance dialysis in 27 dialysis facilities. Of these, 609 patients treated by hemodialysis (HD) were in subgroups large enough to compare with those from the National Health and Nutrition Examination Survey (NHANES) II. Diabetic patients were significantly different from nondiabetic patients; therefore, the two groups were analyzed separately. Male HD patients (diabetic and nondiabetic) did not differ significantly from the NHANES II data. Diabetic HD females did not differ significantly from the NHANES II data, except for the TSF of black women older than 55 years. Measurements of nondiabetic HD females (black and white) were significantly below the NHANES II data. In 138 continuous ambulatory peritoneal dialysis (CAPD) patients, measurements were similar to those of HD patients.
