BMI calculation of older obese is marked with following limitation: Difficulty in height measurement - due to inability to start straight or having other physical anomalies. Shift in body composition - location and amount of fat deposition differs in young and older. Hydration status- with age chances of dehydration is high and this creates errors in calculation of body fat ( as electrical measurements are related to hydration levels). Thus correct option is (d) -all the above.
