Explanation of the Broca Index

The Broca Index is a measure of the normal weight of a person. It was developed by Paul Broca, a French physician, surgeon and anthropologist (1824-1880).

The Broca formula for the normal weight is: Body height in centimeters minus 100.

The Broca formula for the ideal weight of women is: body size in centimeters minus 100 and deduct 15 percent from the result.

The Broca formula for the ideal weight of men is: body size in centimeters minus 100 and deduct 10 percent from the result.

The Broca index is only a rough estimate and is best suited to the range of medium body sizes; For very large and very small body sizes, the BMI is somewhat more precise (a limit observation can illustrate the limitation: how much can a person with 1 m body size be according to Broca?) The Broca ideal weight is too low for a very small body size and very high. Graphically, the Broca ideal weight is a straight line as a function of the body size, the body mass index is a slightly curved curve (parabola).
