In light of the vast amount of research that has been done on the growth and development of children, Pennsylvania has given this topic high priority and has made it part of our state law under the state mandated school health program.
In order to comply with the state’s mandated health program, your certified school nurse on an annual basis assesses your child’s height, weight, BMI, % Age, and vision (Kindergarten through Grade 12), hearing (Kindergarten, Grades 1, 2, 3, 7, 11), and scoliosis (Grades 6 and 7).
The calculation of your child’s body mass index is a mathematical calculation that is performed using your child’s height and weight measurements. The body mass index (BMI) is gender and age sensitive. Your child’s BMI is compared to the BMI of other children in the US of the same gender and age. This calculation comes to you in the form of a percentile. For example: If your child’s BMI is in the 60tth percentile, this means that compared to children of the same gender and age across the United States, 60% have a lower BMI than your child.
Because your child’s growth is a “process,” these numbers (height, weight, BMI) are constantly changing. The BMI that your nurse calculated is based upon your child’s height and weight measurements at the time of your child’s school health screening.
Your child’s BMI is influenced by genetic makeup, state of health, dietary intake, and physical exercise. Serious athletes may have a higher than expected BMI due to their increase in muscle mass, as muscle weighs more than fat.
Because this is Pennsylvania State Law, it is required that your school nurse calculate this measurement each year as part of your child’s growth and development assessment. It is meant to be one indicator, along with many other indicators, of your child’s health and development.
Your child is NOT given this information at any time. The certified school nurse makes the calculations after the child’s health screening session and notes this information in your child’s school health record. This medical record is kept confidential.
A BMI UNDER 5%: AT RISK FOR UNDERWIEGHT
A BMI BETWEEN 5-85%: HEALTHY WEIGHT
A BMI >85-<95%: OVERWEIGHT (formerly, at risk for overweight)
A BMI 95% AND ABOVE: OBESE (formerly, overweight)
If your child’s BMI falls within the healthy range, you will not be notified. If your child’s BMI is less than 5% or greater than 85% your certified school nurse will send a letter home in the US mail. This letter will be addressed to the parent/guardian of the child. The letter is intended to be informative and helpful. It emphasizes that the BMI should be considered as one screening tool and should not be considered as a definitive measure, as the indicator does have limitations.
Your child’s health care provider knows your child and your family history. He/she is the best person to evaluate whether or not your child’s measurements are within a healthy range. Your health care provider can assist you in planning for a healthful diet and exercise program for your child.
We encourage you to discuss this issue with your child’s physician.
