Schools have been vilified for giving kids access to soda in vending machines. But new data suggests that school soft drink sales may not be an important factor in how much soda kids drink.
In the current issue of The Journal of Nutrition Education and Behavior, researchers compared soda consumption among nearly 500 students in Maine who attended seven schools over two school years. Four of the schools cut back on soft drink availability at the schools, while three of the schools made no changes.
Notably, all the students were drinking less soda by the end of the study period, but there were no meaningful differences in overall soft drink consumption among the different schools. The data suggest that curbing soft drink availability at school doesn’t result in meaningful changes in beverage consumption patterns. While there were no changes in overall soda consumption, there was a notable shift in diet soda drinking among girls. If the school cut back on soda availability, girls were less likely to drink diet soda, compared to girls in schools that made no changes.
The data are the latest to suggest that schools may not play as big of a role in kids’ poor eating habits as widely believed. Last year, The American Journal of Public Health published a provocative study showing that childhood weight problems often get worse in the summer, when kids are out of school.
Data from kindergarteners and first graders found that body mass index increased two to three times as fast in summer as during the regular school year. Minority children were especially vulnerable, as were children who were already overweight.
