Example: Body Mass Index-for-age

JS is a 10 year old girl with trisomy 21. Her growth charts indicate the following:

			Stature-for-age has been consistently below the 5th percentile.
			Weight-for-age has increased from below the 5th percentile at ages 6 1/2 years and 8 years to between the 25th and 50th percentiles at age 10 years.

			BMI-for-age has increased from close to the 25th percentile at ages 6 1/2 years and 8 years to between the 90th and 95th percentiles at age 10 years.

This information is shared with JS's parents, along with concerns that JS is at risk for overweight. A referral is made to a registered dietitian who has experience working with children with trisomy 21. JS's food pattern is modified slightly, and after six months, her rate of weight gain has slowed, and his BMI-for-age is more appropriate.
