Abstract:The most frequently used measure of being overweight or obese is based on the body mass index (BMI). The BMI is defined as weight/height2 (with weight in kilograms and height in metres). Adults with a BMI between 25 and 30 are defined as overweight, and those with a BMI over 30 as obese (WHO, 1997). This classification may not be suitable however for all ethnic groups, and adult thresholds are not suitable for children.
