What does this mean?
BMI is calculated using your child’s weight and height and is then used to find the corresponding BMI-for-age percentile for your child’s age and love.
BMI-for-age percentile shows how your child’s weight compares to that of other children of the same age and love. For example, a BMI-for-age percentile of 65% means that the child’s weight is greater than that of 65% of other children of the same age and love.
Based on the height and weight entered, the BMI is 14.3, placing the BMI-for-age below the 1st percentile for boys aged 13 years 0 months. This child is underweight and should be seen by a healthcare provider for further assessment to determine possible causes of underweight.
What should you do?
Regardless of the current BMI-for-age category, help your child or teen develop healthy weight habits and talk with your health care professional as part of ongoing tracking of BMI-for-age. If your child has significant weight loss or gain he or she should be referred to and guided by a health professional.
Practice healthy weight habits
Encourage children and teens to practice healthy weight habits by:
Eating healthy foods and beverages including water
Participating in physical activity on most (preferably all) days of the week
Getting adequate sleep
Limiting television viewing
For more information, see Tips to Promote Healthy Eating and Physical Activity for Children and Teens.
Keep track of BMI-for-age
Check BMI-for-age annually, or more often if recommended by the child’s healthcare provider. Tracking growth patterns over time can help you make sure your child is achieving or maintaining a healthy weight. A single BMI-for-age calculation is not enough to evaluate long-term weight status because height and weight change with growth. If your child has significant weight loss or gain he or she should be referred to and guided by a health professional.
Please keep in mind that this BMI calculator is not meant to serve as a source of clinical guidance and is not intended to be a substitute for professional medical advice. Since BMI is based on weight and height, it is only an indicator of body fatness. Individuals with the same BMI may have different amounts of body fat. Persons may consider seeking advice from their health-care providers on healthy weight status and to consider individual circumstances."
