Dual Use of Off-Premise Outlets for Alcohol and Grocery Purchases: Results From the East Bay Neighborhoods Study.

objectiveAlcohol privatization efforts have enabled consumers in many states in the United States to purchase alcohol in a variety of off-premise outlets, including grocery stores. This study examines the dual use of outlets to purchase both alcohol and groceries and the extent to which dual use is related to individual income, neighborhood income, and local physical availability of alcohol.

methodThe East Bay Neighborhoods Study surveyed residents from 72 microecological neighborhoods across six cities in Alameda County, California. Eligible respondents who purchased alcohol in the last year (

resultsSeventy-three percent of participants reported dual use of their most used outlet for groceries and alcohol. In adjusted models, dual use of the outlet was not associated with individual income, alcohol use, or neighborhood outlet density but was positively associated with neighborhood income and the number of outlet visits. After adjustment, dual use of the most used outlet was associated with 0.77 more visits per 28 days.

conclusionsResults suggest that convenience and reduced time costs for purchasing alcohol encourage the dual use of outlets, particularly in high-income neighborhoods. Differences in the dual use of outlets and frequency in outlet use by neighborhood environments highlight the importance of understanding the role of alcohol availability in distinct neighborhood income and outlet-level contexts.
