(NEW YORK) — State laws that curb the sale of junk food in schools may be helping combat childhood obesity, according to the findings of a new study published Monday in the journal Pediatrics.
In the first national study to measure the effectiveness of state laws that curb the sale of sugary snacks and drinks, researchers found that kids in grades five through eight who lived in states with stronger laws actually gained less weight than kids in states without them.
“[I]t really shows that there can be an effect — a positive effect — by curbing the sale of junk food and sweetened drinks,” said Dr. Keith Ayoob, associate clinical professor of pediatrics at the Albert Einstein College of Medicine in New York City. Ayoob was not involved in the study.
These findings, though not considered hard proof because the differences were slight, are increasing optimism among public health experts. Ayoob says states that do not have laws limiting the consumption of junk food and low nutrient drinks in schools might want to consider adopting legislation that would do so.
And while curbing junk food in school is a good start, it’s critical that healthy habits extend beyond the classroom, Ayoob says. “That’s where maybe parents can have a bigger impact.”
The study was conducted over three years and involved more than 6,000 kids in 40 states.
