Book Description
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.
