Demographic Groups Likely Affected by Regulating Sugar-Sweetened Beverage Portion Sizes.

introductionSugar-sweetened beverages are a key driver of obesity. Portion-size regulations typically limit the volume of unsealed sugar-sweetened beverage containers to 16 fluid ounces. These regulations could reduce sugar-sweetened beverage consumption, but whom these policies would affect remains unknown. This study evaluates demographic groups likely affected by hypothetical national portion-size regulations modeled on policy language and scopes from New York City and California.

methodsData from adults (aged 18-65 years, n=6,594) in the National Health and Nutrition Examination Survey (2013‒2016) were used to classify individuals as likely affected if they consumed a sugar-sweetened beverage larger than 16 fluid ounces from a potentially regulated food source during at least 1 eating occasion. Two classifications of affected food sources were evaluated: (1) excluding convenience stores (New York City scope) and (2) including convenience stores (California scope). In 2020, analyses were conducted using logistic regression to examine associations between affected status and age (<35 and ≥35 years), sex, race/ethnicity (white, non-Hispanic, black, non-Hispanic, andHispanic), education (without college degree and with college degree), and income (≤185% and >185% of the federal poverty line).

resultsPortion-size regulations would affect 8.87% of adults (New York City scope) and 14.71% of adults (California scope). Regulations had a greater potential effect on adults who were aged <35 years, male, and without a college degree (all p<0.05). Differences between demographic groups would be larger in magnitude using California's policy scope.

conclusionsPortion-size regulations would likely have a greater effect on younger, male, and less-educated adults. Policy effects would likely be larger if these regulations are written to encompass more food sources.
