Introduction

Body mass index or BMI is a measure of body fat based on the ratio of weight and height (bodyweight in kilograms divided by height in metres squared). The normal range of BMI for an adult is 18.5 to 24.9 kg/m2.

Overweight for children is defined as a BMI (appropriate for age and sex) that is likely to be equal to 25 but less than 30 at age 18 years. Obesity for children is defined as BMI (appropriate for age and sex) that is likely to be 30 or more at age 18 years.
