Conclusion Isolated changes to the school food environment may have unintended consequences unless policymakers incorporate other initiatives designed to discourage overall soda consumption.
These studies utilized several independent data sources that sampled students nationwide. The study linked student data from the National Youth Physical Activity and Nutrition Study with state-level data on soda taxes, restaurant taxes, and laws governing the sale of soda in schools in Policies have achieved their direct goal of reducing SSB access, but there is relatively little evidence that such changes influence students' consumption of soda or overall SSBs.
Nearly all categorical measures had similar distributions regardless of vending machine access. We focused only on soda, not other SSBs, because soda has been the primary target of policy changes on the high school level.
Share: FULL STORY Banning vending machines from schools can actually increase soda and fast food consumption among students if it's the only school food policy change implemented, according to research conducted at the University of Illinois at Chicago.
Statistical analysis Due to their respective distributions, the 4 dependent variables were analyzed using different types of regression models — a negative binomial model for total servings of soda in the past 7 days, a Poisson model for fast food consumption in the past 7 days, and a logistic model for daily soda consumption and lunch source.
First, we estimated the association between vending machine access and each dependent variable.
