Introduction: Studies show that outdoor advertisements for unhealthy, consumable products are associated with increased intake and often target youth, low-income neighborhoods, and neighborhoods of color. Despite evidence that overconsumption of sugary drinks contributes to obesity and other chronic conditions, little is known specifically regarding the patterns of outdoor sugary drink advertising. Methods: The number of outdoor, street-level advertisements featuring sugary drinks was assessed in a random sample of retail-dense street segments (N=953) in low, medium, and high-poverty neighborhoods in each of New York City's 5 boroughs in 2015. Negative binomial regression was used to determine associations between sugary drink ad density, poverty level, and other census tract-level demographics (2009−2013 estimates) in each borough and New York City overall. Data were analyzed in 2017−2019. Results: In New York City and in 3 of 5 boroughs, sugary drink ad density was positively associated with increased percentages of black, non-Latino residents (New York City: incidence rate ratio=1.20, p<0.001; Bronx: incidence rate ratio=1.30, p=0.005; Brooklyn: incidence rate ratio=1.18, p<0.001; Manhattan: incidence rate ratio=1.20, p<0.05). Positive associations were also observed with poverty level in Brooklyn (low versus medium poverty: incidence rate ratio=2.16, p=0.09; low versus high poverty: incidence rate ratio=2.17, p=0.02) and Staten Island (low versus medium poverty: incidence rate ratio=3.27, p=0.03). Conclusions: This study found a consistent positive association between the density of outdoor sugary drink advertisements and the presence of non-Latino black residents in New York City and, in some boroughs, evidence of a positive association with neighborhood poverty. These findings highlight the inequities where sugary drinks are advertised in New York City.
