From the NY Times:
The problem was the letter Karlind discovered, tucked inside her report card, saying that she had a body mass index in the 80th percentile. The first grader did not know what â€œindexâ€ or â€œpercentileâ€ meant, or that children scoring in the 5th through 85th percentiles are considered normal, while those scoring higher are at risk of being or already overweight.
Yet she became convinced that her teachers were chastising her for overeating.
Since the letter arrived, â€œmy 2-year-old eats more than she does,â€ said Georgeanna Dunbar, Karlindâ€™s mother, who complained to the school and is trying to help her confused child. â€œSheâ€™s afraid sheâ€™s going to get in trouble,â€ Ms. Dunbar said.
The practice of reporting studentsâ€™ body mass scores to parents originated a few years ago as just one tactic in a war on childhood obesity that would be fought with fresh, low-fat cafeteria offerings and expanded physical education. Now, inspired by impressive results in a few well-financed programs, states including Delaware, South Carolina and Tennessee have jumped on the B.M.I. bandwagon, turning the reports â€” in casual parlance, obesity report cards â€” into a new rite of childhood.
Legislators in other states, including New York, have proposed them as well, while some individual school districts have adopted the practice.
Here, in the rural Southern Tioga School District, the schools distribute the state-mandated reports even as they continue to serve funnel cakes and pizza for breakfast. Some students have physical education for only half the school year, even though 34 percent of kindergartners were overweight or at risk for it, according to 2003-4 reports.
