A quick and easy guide for use in the clinical setting is the Broca Index. This measurement relates weight in kilograms to height in centimeters, but makes no allowance for sex- The Broca Index: Height (cm) - 100 = Ideal weight (kg), For example: A patient whose height is 162.5 cm tall. Ideal weight = 162.5–100 = 62.5 kg Brodsky has modified the Broca Index to allow for gender differences, based on the premise that females have a higher ratio of fat tissue compared to total body weight. The Modified Broca Index: Males: Height (cm) - 100 = Ideal weight (kg) Females: Height (cm) – 105 = ideal weight (Kg).
