TARGETS FOR CONTROL
All the target levels given below are generalisations and individual
targets MUST be established. Laxity may be allowed in elderly patients;
certain conditions require a much tighter control, e.g. pregnancy, maculopathy,
Ideally, Body Mass Index (BMI) should be used to calculate optimal weight using the following formula:
Weight in Kg
BMI = -------------------------
Height in meters2
> 23 = Overweight; > 27 = Obese ( for people from the Indian subcontinent)
Care must be taken that the weight is not decreased below the lower limits, as a BMI of 18.5 signifies low body weight.
For BMI Tables, see Appendix 2a

The method to measure the waist circumference and Country/Ethnic group specific diagnostic waist circumference measures in given in Appendix 1c
