- Body mass index (BMI) is calculated as follows:
- BMI = (Weight in kg)/(Height in m)2
- BMI is an effective screening tool, not a diagnostic one.
- For children, BMI is age and gender specific.
- Children who are at the 85th to 95th percentiles are considered overweight.
- Children who are at or above the 95th percentile are considered obese.
- Children who are below the 5th percentile are considered underweight.
