Quality and outcomes

BMI is a measure of a person's size based on their weight and height. If the number is too high or too low there may be health problems. The Cystic Fibrosis Foundation Patient Registry shows a strong association between a higher BMI percentile and better lung function in children with CF. Gaining weight and growing at a normal rate can be hard for children with CF. Therefore, with CF, a high BMI percentile is better.
