BMI Mappings with clinical systems

The BMI mappings are provided in the 'General Data Mappings' Appendices under Measurements for each clinical system.
BMI, where calculated from height and weight, will use the weight date as the measurement dates and requires that height has been recorded in the following timeframes:

Age >= 18:

Height/weight dates are within 5 years of each other AND
At least one height recorded since age 17 (for age 18-24)
At least one height recorded since age 25 (for 25+)

OR

Age < 18:

Height/weight dates are within 1 year of each other
