The letters are coming home from schools that weigh students as classes begin and then calculate their body mass index.
If the index is above the recommended level, a note goes home to the parents warning them that their children are considered at risk for obesity issues.
Hope Green has two children in school, she told ABC News "the last thing they need is the school to now step in. You're too skinny, you're too fat," she said.
Currently 20 states from Arkansas to California to Illinois take part in the program by sending sealed letters home to parents.
Doctors argue that BMI is the best indicator of a child’s current health based on his/her height, weight and overall body structure.
But parents are afraid the letters will put more pressure on kids, many of which are already preoccupied with their body image.
Statistics say 40% of nine to ten year old girls have already been on a diet, something medical professionals say is unhealthy.
Reports say the children began calling the notes “fat letters” themselves and they have gone out to kids as young as six.
Doctors admit boys have eating disorders but the biggest concern comes from the parents of girls.
Shannon Park has two daughters and she is dead set against the measurements.
“Their bodies are changing and then they get this number that says, ‘Oh, you know, you’re not the right number.” She finished by saying It’s just a horrible way to start womanhood.”
What do you think? Should schools do BMI measurements on the kids and send them home? Please leave your thoughts in the comments section below.
