Race, Ethnicity, and Neighborhood Food Environment Are Associated with Adolescent Sugary Drink Consumption During a 5-Year Community Campaign.

backgroundA multi-level county-wide campaign to reduce sugary drink consumption was associated with significant decreases in retail sales of soda and fruit drinks. The aim of the current study was to examine changes in adolescent beverage consumption during the campaign by race/ethnicity and neighborhood food environment.

methodsBeverage consumption among adolescents was evaluated at four time points in a repeated cross-sectional survey of a racially and ethnically diverse sample of sixth graders (N = 13,129) from public middle schools in the county. Each school's surrounding attendance zone (i.e., neighborhoods where students live) was characterized as providing high or low exposure to unhealthy food retail (e.g., convenience stores, fast-food restaurants). Logistic and multiple linear regression models were used to evaluate changes in beverage consumption over time by student race/ethnicity and high versus low unhealthy food exposure.

resultsOver the 5 years, there were significant declines in the overall share of students who reported daily sugary drink consumption (49.4 to 36.9%) and their reported daily calories from these products (220 to 158 calories). However, disparities were observed, with higher levels of consumption among Black and Hispanic youth and among youth living in neighborhoods with more unhealthy food retail. Notably, Black students living in healthier neighborhood food environments reported significant decreases in daily consumption and calories after 5 years, while Black students living in neighborhoods with more convenience stores and fast-food outlets did not.

conclusionThese findings suggest that both race/ethnicity and neighborhood food environments are important considerations when designing interventions to reduce sugary drink consumption among adolescents.
