Body Mass Index (BMI) is an approximate measure of whether someone is overweight or underweight. BMI of a person is calculated by dividing the weight of the person in kilograms by the square of their height in metres. BMI attempts to categorize a person as Normal, Underweight, Overweight or Obese based on the value obtained by attempting to quantify the amount of tissue mass (muscle, fat, and bone) in the individual.
|Classification||Principal cut-off points||Cut-off points for Asians|
|Obese Class I||30.0-34.9||27.5-32.4|
|Obese Class II||35.0-39.9||32.5-37.4|
|Obese Class III||>=40.0||>=37.5|
For Asian populations classifications remain the same as the international classification but that public health action points for interventions are set at 23, 27.5, 32.5 and 37.5. We address eligibility and prioritization for bariatric surgery within the coloured zones above
