‘Fat Letters’ Worry Students, Parents and Experts

iStockphoto/Thinkstock(NEW YORK) -- A growing initiative by some schools across the country has students and parents up in arms. The schools are measuring students at an annual weigh-in, and sending reports home telling parents whether their child’s body mass index is healthy or dangerous.

Schools in 19 states, from Arkansas to Illinois, participate in the annual student weigh-ins.

Some pediatricians say body mass index (BMI) readings are helpful in combating childhood obesity, which is a growing problem.

Right now, BMI readings are “the best means we have to determine whether a child’s weight is healthy or unhealthy,” said Dr. Lanre Omojokun Falusi, a Washington, D.C.-based pediatrician and a spokesperson for the American Academy of Pediatrics.

But some eating disorder experts worry that taking the readings may do more harm than good.

“I would like to see BMI testing in schools banned,” said Claire Mysko of the National Eating Disorders Association.  “For those who are already insecure about their weight, these tests can … potentially trigger an eating disorder.”

Experts are concerned about the potential for eating disorders in girls and boys, but are especially concerned about girls given that girls are more likely than boys to experience such disorders. More than 40 percent of 9- and 10-year-old girls have already been on a diet.  As many as 60 percent of all children between the ages of 6 and 12 years old are worried about their weight, according to Duke University.

Some children who get the “fat letters” -- as students themselves call them -- are as young as 6 or 7 years old.
