Dear Colleagues
Please, can you direct me to the best way of correcting a body surface area when the body weight is out of proportion to the height as in obesity for example.
The formulae used to calculate or derive the body surface area from the height and weight generally assume a reasonably normal body mass in relation to height. For example a man standing 185cm tall can be expected to weight 75-80kg and a lady of 162cm about 60kg.
How does one best handle a 152cm tall lady weighing 72kg? Or, a 203cm tall man weighing 108kg?
Given that a sphere is the smallest surface area for a given volume does applying the standard BSA calculations to obese people lead to an overestimate of the BSA?
I appreciate that this is a bit specialised but if someone can direct me to a review article on the subject (may be from before the second world war even?) I would be grateful.
Happy New Year.
Yours sincerely
