BMI in Children: Why a BMI of 24 at Age 8 Is Overweight

For children, BMI is interpreted using age- and sex-specific percentiles, not adult categories.

An 8-year-old girl with BMI 24 is at the 98th percentile—heavier than 98% of peers. This classifies as overweight.

Health Risks

Childhood overweight increases risk of heart disease, stroke, type 2 diabetes, certain cancers later in life.

Action Steps

• Encourage fruits, vegetables, whole grains
• Limit processed foods, sugary drinks, unhealthy fats
