The study is new evidence that improving the quality of school meals through legislation might be one way to help shift the trajectory of childhood obesity, which has been rising for decades and now affects about 1 in 5 U.S. kids.
A 7th grader carries her plate which consists of three bean chili, rice, mandarins and cherry tomatoes and baked chips during her lunch break at a local public school, Saturday, Feb. 11, 2023, in the Brooklyn borough of New York. A 2010 federal law that boosted nutrition standards for school meals may have helped curb obesity among Americas children _ even teenagers who can buy their own snacks, according to a study published Monday, Feb. 13, 2023, in the journal JAMA Pediatrics.
The study is new evidence that improving the quality of school meals through legislation might be one way to help shift the trajectory of childhood obesity, which has been rising for decades and now affects. Whether the program has begun to turn the tide for the whole country, and not just the groups of kids studied, is still unclear. About 30 million children in the U.S. receive school lunches each day.
It found that a body mass index for children, adjusted for age and gender, fell by 0.041 units per year, compared to before the law took effect. That amounts to about a quarter of one BMI unit per year, Chandran said. There was a slight decline in kids who were overweight or obese, too, the study showed.
Previous studies have shown weight-related effects of the federal law among children from low-income families. The new study is the first to find lower BMI in kids across all income levels. But some researchers cautioned against interpreting the study’s findings too broadly. Some of the children included in the study might not have been enrolled in school meals programs, or their district may not have fully implemented the nutrition requirements, said Kendrin Sonneville, associate professor of nutritional sciences at the University of Michigan School of Public Health.

Study hints healthier school lunch can reduce obesityA 2010 federal law that boosted nutrition standards for school meals may have begun to help slow the rise in obesity among America’s children — even teenagers who can buy their own snacks, a new study showed.

The study is new evidence that improving the quality of school meals through legislation might be one way to help shift the trajectory of childhood obesity, which has been rising for decades and now affects about 1 in 5 U.S. kids.
