To assess the validity of standards for weight, arm circumference, triceps skinfold, and arm muscle circumference commonly used to assess the nutritional status of hospitalized patients, these standards were applied to data for the normal U.S. population. Moderate depletion was defined as a value between 60 and 90 percent of the standard; severe depletion was defined as a value below 60 percent of the standard. The standards themselves were found to differ substantially from the population averages, and this method of classifying an individual does not take into account the fact that there is more variation in the population for some measures than for others. As a result, the proportion of individuals classified as depleted varied greatly between measures and also between sexes and ages. Over half of all young women would be classified as moderately depleted based on the arm muscle circumference. Over half of young men would be classified as depleted based on the tricep skinfold, and half of these would be classified as severely depleted. It is recommended that the use of these standards and this method of interpretation be abandoned and replaced by the use of tables of percentiles for the U.S. population.
