On the need for national-, racial-, or ethnic-specific standards for the assessment of bone maturation

Abstract

In an attempt to overcome ethnic and racial differences in skeletal maturation, the use of ethnic-specific standards has been suggested. Do we need such standards? Based on a fundamental understanding of phenotypic plasticity and an individual's ability to respond to environmental cues, the author argues that we do not need ethnic-specific standards for bone maturity. I suggest that we use a unified international standard of bone maturity for comparing the health, nutrition, and quality of life of all children, regardless of their race, nationality, and ethnicity.
