While many schools have ousted sodas, a new study finds fruit drinks, sports drinks and other beverages with added sugar continue to be widely available.
University of Michigan researchers surveyed nearly 2,000 public schools.
A quarter of high school students were able to buy sodas in school in 2011, compared to more than half in 2006. Last year, about 83-percent could purchase other beverages with added sugar like sports and fruit drinks.
Many medical experts say those drinks fuel childhood obesity.
