Larger taxes on soda drinks needed to help curb children obesity

    To reduce soda consumption in fighting children obesity will require larger taxes, a new study by RAND researchers showed.
    "If the goal is to noticeably reduce soda consumption among children, then it would have to be a very substantial tax," said Roland Sturm, the study's lead author and a senior economist at RAND, a nonprofit research organization.
    "A small sales tax on soda does not appear to lead to a noticeable drop in consumption, let alone reduction in obesity."
    Taxes on soft drinks and other sugar-sweetened beverages have been proposed as part of many anti-obesity efforts to discourage purchase of the high-calorie drinks so as to curb excess weight gain.
    The researchers estimated the potential effect of soft drink taxes on children's consumption and weight by examining differences in existing sales taxes on soft drinks between states.
    The study involved 73,000 children who reportedly drank an average of six sodas per week, but there was wide variation among the group.
    Fifteen percent reported drinking no sodas in the prior week, while 10 percent consumed two or more sodas per day. The amount of soda purchased at school was small.
    The analysis could find no significant link between the consumption of soda or weight gain among children and differential taxes on sodas versus other foods. Existing differential taxes (taxes that are imposed on sodas and not other food items sold in grocery stores) are small, averaging 3.5 percent and none are larger than 7 percent.
    The higher sales tax on soda in some states did seem to reduce soda consumption and curb higher risk for children obesity -- those who were heavier, children from low-income families, African-American children and those who watched a lot of television. Children in all these groups drank more soft drinks than children in general.
    The impact was more pronounced for children from these groups who had access to soft drinks at school. Price effects may be stronger in school settings where cafeterias or vending machines round prices up, although there are alternative explanations, according to the study published by the April journal of Health Affairs.
    The fact that small sales taxes have no strong effect on consumption should not be surprising and the much larger soda taxes recently proposed in several areas are likely to have a much larger effect, Sturm said.
    In order for soda taxes to be most effective, researchers say they should be structured as an excise tax that will increase the shelf price of the product rather than a sales tax collected at the cash register. The latter may often not be clearly linked to the purchase of soda.
    One such approach to creating an excise tax could be to levy a tax on the sugar content of soda drinks.
    "Soda taxes do have the potential to help reduce children's consumption of empty calories and have an impact on obesity, but both their size and how they are structured are key to whether they create measurable impact," Sturm said.
