Infant and child anthropometry

Although over 800 references to child and infant anthropometry are in the literature, most have limited validity and application to current populations. Functional measures required by industry and government for federal safety standards for design of dummies, child products, furniture, or protective devices such as restraint systems have either been incomplete, inadequate, or nonexistent. Some of the limitations influencing validity of existing data have been outlined for the potential user. As a start toward obtaining necessary functional anthropometric data, The University of Michigan is currently conducting a study sponsored by the U.S. Consumer Product Safety Commission to obtain valid nationwide measurements on a representative U.S. population from birth to age 12 years. In this study some 41 measurements, including many functional measures, as well as seated and supine whole-body centers of gravity, are being taken utilizing a new automated anthropometric minicomputer system. A number of specialized infant and child measurement devices have been designed and used with pressure transducers providing a new basis for more accurate and precise measurement of body dimensions than has been possible with previous standard anthropometric instruments. This information has already provided a basis for an improved federal safety standard for infant crib slat width.
