BMI (Body Mass Index) is a way of working out if you’re a healthy weight based on your height. The World Health Organisation’s definition for BMI (for adults) is that a result of 25 or more is overweight and 30 or more is obese.
As height is taken into account in how the BMI result is calculated, this ideal range is the same for everyone, regardless of height, age or gender. However, when looking at your BMI you should also take your Body Fat Content into account. If you’re very muscular, such as a rugby player, you might have a high BMI, but a healthy Body Fat.
As with all results from the Wellpoint kiosk, if you’re unsure or concerned about your results, speak with a health professional such as an OH nurse, GP or pharmacist.
The Wellpoint works out your BMI using this formula – your weight in kilograms, divided by the square of your height in meters. So if you’re 5 foot 10, and the kiosk weighs you at 12 stone 4 pounds, that gives you a height of 1.78m and a weight of 78kg. So your BMI = 78 / (1.78 x 1.78) = 24.6. This is under 25, so is a healthy weight.
