Measures of body size based on height, weight, and reported ideal weight: conceptual distinctions and empirical demonstrations.

Using height, weight, and self-reported weight, eight additional measures of body size were computed. The purpose of this paper was to specify conceptual distinctions and test hypothesized relationships among those newly constructed measures. Using a sample of healthy African American and European American women, correlations among the measures and race differences were assessed. High correlations suggested only two independent constructs, but theoretical considerations would suggest retaining, in addition to the traditional measure of body mass index, three new constructs: ideal body mass, a discrepancy measure, and a desirability measure. The only significant race difference was on ideal body mass. African American women reported a larger ideal body mass index than European American women. The use of actual versus self-report measures of height and weight, different conceptualizations of ideal weight, and clinical implications also were discussed.
