Exploring the relationship between the alcohol policy environment and nondiscrimination laws: Implications for binge drinking disparities among LGB adults in the United States.

BACKGROUND

Alcohol policies reduce population-level binge drinking; however, they may not reduce binge drinking disparities between different populations. We examined the association between the alcohol policy environment and binge drinking among Lesbian, Gay and Bisexual (LGB) and heterosexual adults in the presence and absence of state laws protecting LGB people from discrimination.

METHODS

The 2015-2018 Behavioral Risk Factor Surveillance System (BRFSS) provided information about individual-level binge drinking, sexual identity, and individual-level covariates. The Alcohol Policy Scale (APS) score measures the strength of the alcohol policy environment. Presence of state-level nondiscrimination protections based on sexual orientation came from the Movement Advancement Project. Logistic regression models were used to test whether nondiscrimination statutes modified the association between the alcohol policy environment and binge drinking and whether this interaction differed for LGB and heterosexual adults.

RESULTS

Among women, a 10 percentage-point increase in APS score was significantly associated with 7% lower odds of binge drinking in states with inclusive nondiscrimination laws (aOR: 0.93 [95% CI: 0.89-0.97; p = 0.0003]) but was not associated with binge drinking in states without inclusive laws (aOR: 0.98 [95% CI: 0.93-1.03] p = 0.4781). Moreover, binge drinking disparities comparing lesbian/bisexual women with heterosexual women were narrower in states with inclusive nondiscrimination laws. No significant association was found among men.

CONCLUSIONS

Binge drinking disparities between lesbian and heterosexual women are negligible in states with inclusive laws and strong alcohol policy environments. Inclusive nondiscrimination laws are an indicator of less structural stigma directed at lesbian and bisexual women.
