Objective: Neighborhood characteristics have been shown to influence lifestyle behaviors. Here we characterized alcohol outlet density in Los Angeles County, California, and Hawaii and assessed the association of alcohol outlet density with self-reported alcohol intake in the Multiethnic Cohort.
Method: Participants (n=178,977) had their addresses geocoded, at cohort entry (1993-1996), and appended to block group-level alcohol outlet densities (on- and off-premises). Multinomial logistic regression was performed to assess the association between self-reported alcohol intake and on- and off-premise alcohol outlet densities by each state. Stratified analysis was conducted by sex, race, and ethnicity.
Results: Overall, we did not find associations between alcohol outlet density and self-reported alcohol intake in Los Angeles County, but we found that on-premise alcohol outlets were associated with 59% (OR=1.59, 95% CI:1.29,1.96) increased odds of consuming >2 drinks per day in Hawaii. Women living in neighborhoods with high density of on-premise alcohol outlets (Los Angeles County OR=1.15, 95% CI: 0.95,1.40) and (Hawaii OR=2.07, 95% CI: 1.43,3.01) had an increased odds of >2 drinks per day.
Conclusion: This study suggests that neighborhood factors are associated with individual level behaviors and that there may be a need for multilevel interventions.
