Body mass index, or BMI, is a measure of body fat based on height and weight. It is used to screen for weight problems in children and track their growth patterns. Measuring BMI in children is important for identifying those who are at risk for obesity and related health problems.
The formula for calculating BMI is weight (kg) / height (m2). A child’s BMI is then compared to a growth chart to determine if they are underweight, normal weight, overweight, or obese. Measuring BMI in children is a simple and inexpensive way to assess their weight status and track their growth patterns. It can help identify children who need further evaluation and intervention to prevent or treat weight problems.
