In October of 1981, OPNAVINST 6110.1B was promulgated establishing the percentage of body weight contributed by fat mass BF as the basis for weight control decisions. Tables based upon the work of Wright, Dotson, and Davis allowing prediction of BF from abdominal and neck circumferences were accepted for use on an interim basis. This report covers validation of the equation of Wright and his co-workers, as well as the development and cross- validation of a new equation which offers improved prediction of BF for U.S. Navy male personnel. Anthropometric measures consisting of 8 skinfold thicknesses, 12 body circumferences, height, and body weight were made on 602 male U.S. Navy personnel aged 18-56 years mean age 32 yrs. In addition, each participant had her body density and BF determined by underwater weighing. Validity of the equation of Wright and co-workers was assessed by correlation between predicted and measured BF. The correlation coefficient 0.87 std. err. meas. 3.99 BF. Errors in prediction near the Navy minimum standard of 22 BF, dictated development of a new equation.
