Clinical Tracking of Severely Obese Children: A New Growth Chart

Abstract

The 2000 Centers for Disease Control and Prevention growth charts are unable to accurately define and display BMI percentiles beyond the 97th percentile. At Children’s Hospital Colorado, we created new growth charts that allow clinicians to track and visualize BMI values in severely obese children. This growth chart defines a child’s BMI as a “percentage of the 95th percentile.” It has the potential to allow clinicians to define subgroups of severe obesity, monitor trends in obese children, and measure treatment success or failure.
