The Impact of Neighborhood Alcohol Outlet Density on Alcohol-related Health Outcomes
Researchers in Louisiana and California conducted a cross-sectional study to assess the association between alcohol outlet density and self-reported alcohol-related health outcomes (i.e., sexually transmitted infection [STI], motor vehicle accidents, injury, liver problems, hypertension, and violence) in the last year. They also sought to determine whether these associations were mediated by individual alcohol use. Three measures of alcohol outlet density were used: neighborhood density (number of outlets per square mile of census tract), individual density (number of outlets within 1 mile of each subject’s home), and distance to the nearest outlet from each subject’s home.
- The average distance to the nearest outlet was 0.5 miles. The average outlet density within 1 mile was 1.1.
- In analyses adjusted for age, sex, race, ethnicity, education, location, and income, individual outlet density was associated with STI (adjusted odds ratio [AOR],* 1.80), liver problems (AOR, 1.33), and violence (AOR, 1.31). Distance to the nearest outlet was not associated with STI, liver problems, or violence.
- Individual alcohol use partially mediated the relationship between outlet density, STI, and violence and fully mediated the association between outlet density and liver problems.
