Body Mass Index

Apparently, the new cross-agency medical includes a test of Body Mass Index, which is calculated from height h (in metres) and weight m in kilograms using the following formula:

BMI = m / ( h ² )


The medical suggests that anyone with a BMI over 30 should be referred to a diving doctor to investigate the effect of obesity upon diving. Some questions have been asked about the appropriateness of this test: if you're worried, speak to your doctor (or ask the ships lawyers on scuba-uk!) Doug Taylor kindly came up with a table of maximum weights for height to keep below BMI=30, and Anke Otto added metric equivalents.
