Introduction[edit | edit source]
Body mass index, or BMI, is used to determine a person’s healthy weight range for their height.
- It is useful to consider BMI alongside waist circumference, as waist measurement helps to assess risk by measuring the amount of central fat.
- BMI is a useful measurement for most people over 18 years old. However it is only an estimate and not taking into account age, ethnicity, gender and body composition. It is recommended to check waist measurement and other risk factors[1]
Definition and Classification[edit | edit source]
Body mass index or BMI is a statistical index using a person's weight and height to provide an estimate of body fat in males and females of any age. It is calculated by taking a person's weight, in kilograms, divided by their height, in meters squared, or BMI = weight (in kg)/ height^2 (in m^2). The number generated from this equation is then the individual's BMI number.
Individual variations do exist, and BMI is insufficient as the sole means of classifying a person as obese or malnourished an example being - In elite athletes and body-builders, an elevated BMI does not directly correlate to their health status due to their increased muscle mass and weight falsely increasing their BMI.[2]
The BMI number and classifications are listed below, these classifications for BMI are in use by the NIH and the World Health Organization (WHO)
White, Hispanic and Black individuals
- Severely underweight - BMI less than 16.5kg/m^2
- Underweight - BMI under 18.5 kg/m^2
- Normal weight - BMI greater than or equal to 18.5 to 24.9 kg/m^2
- Overweight – BMI greater than or equal to 25 to 29.9 kg/m^2
- Obesity – BMI greater than or equal to 30 kg/m^2
Asian and South Asian population: overweight - BMI between 23 and 24.9 kg/m^2; obesity - BMI greater than 25 kg/m^2[2]
