Anthropometric Assessment Stature, Weight, and Body Mass Index (Adults)

Direct anthropometric measurements and derived indices describe body size, shape, and composition. They infer information about the body at the tissue level, and they are affected by and reflect changes due to aging and disease. Weight is a limited indicator, because it is related to stature, for example, on average, tall people are heavier than short people. This limitation is reduced in weight divided by stature indices, such as the body mass index or BMI. Stature and weight are covariates in statistical models of body composition¹ and BMI values are associated with morbidity and mortality.² Standardized anthropometric techniques are required to compare clinical and research data, and text and video media describing these techniques are available.^{3, 4} Individuals needing to use anthropometric methods and equipment should consult these available resources for additional information.
