...Amish are a genetically homogeneous group, the study of volunteers' genotypes still showed a genetic diversity that reflected the makeup of the general Caucasian population: Specifically, they exhibited a range of variations on the FTO gene, which previous studies have associated with obesity and high body mass index, or BMI. Experts say about half of all people of European descent possess at least one "heavy" variant of the FTO gene. Within the Amish study group, some volunteers had two copies of a fattening variant; these people were 67% more likely to be obese and were on average 7 lbs. heavier...
School children across England will soon have their Body Mass Index (BMI) tested as part of a new effort to tackle the growing problem of childhood obesity. Parents will be sent a letter telling them whether their child is underweight, a healthy weight, overweight or very overweight. The letter will also include leaflets giving advice on eating healthily, physical activities their child might do and the risks of being overweight...
...tripled over the past three decades, which may be why a few U.S. states already send reports on heavy kids home to parents. The College of Natural Resources at the University of California, Berkeley, published a paper in November 2006 describing the "risks and benefits of BMI reporting in the school setting", and in May 2007, Wyoming started a program in which students' report cards came complete with their BMI...
...Centers for Disease Control and Prevention (CDC) researchers found that childhood-obesity levels may finally have leveled off, more than 30% of American schoolchildren are still overweight, with little indication that rates will drop anytime soon. The CDC defines as overweight those children with a body mass index (BMI)--a rough factoring of height and weight--higher than the 85th percentile of figures from the 1960s and '70s, before the obesity epidemic hit. Obesity is defined as the 95th percentile. That's far from healthy. "The childhood obesity epidemic is a tsunami," says David Ludwig, an obesity researcher at Children...
...ingest up to 50% of their daily calories. Here, Arkansas--a state that has had one of the nation's highest rates of childhood obesity--is in the vanguard. Led by Joseph Thompson, director of the Arkansas Center for Health Improvement, the state in 2004 began tracking the BMI of more than 400,000 children, sending home confidential health reports to parents. BMI is an imperfect metric since it often mistakes a stocky or muscular kid for an obese one, but as a quick way to spot weight problems it can reveal a lot. Officials also eliminated junk-food vending...
