BMI is a calculation derived from height and weight measurements, which can be thoroughly documented by allied health professionals, such as dietitians and nutritionists, who often take these measurements as part of their assessment processes.

This measurement is fundamental in evaluating an individual's weight status and can be influential in diagnosing conditions like obesity or malnutrition based on BMI categories, but it stands alone in terms of direct establishment by allied health professionals without needing medical diagnostic criteria.

Thus, BMI is more distinctly established through allied health documentation than the other conditions listed.
