The study, published this week in The Archives of Pediatrics and Adolescent Medicine, found that many students still consume sugary drinks in schools that have administered the ban.
The researchers found that the proportion of students who purchased sugary drinks at schools in states that removed only soda — 28.9 percent — was similar to the proportion in states that had no bans against any sugary drinks at all — 26 percent. Both groups also reported having identical levels of access to sugary beverages at school: about 67 percent in each category.
The sale of soft drinks in schools has become a lucrative revenue source for many school districts, and a number of states have been reluctant to eliminate them from schools. Some states have instituted only partial bans that remove sodas from schools but not Snapple, Gatorade and other sugary drinks.
