Joint disparity, referent race disparity, referent sexual identity disparity for binge drinking and heavy alcohol use adjusted for age among Black and White sexual identity groups

Variable	Joint disparity	Referent race disparity	Referent sexual identity disparity	Excess intersectional disparity
% [95% CI]	µ11 − µ00	µ10 − µ00	µ01 − µ00	µ11 − µ10 − µ01 + µ00
Binge drinking	21.2 % [12.4, 29.9]	-0.8% [-2.8, 1.1]	4.3% [-1.5, 10.1]	17.7% [6.9, 28.5]
Heavy alcohol use	6.5% [0.6, 12.5]	-1.8% [-2.9, -0.7]	0.0% [-2.5, 2.4]	8.4% [2.0, 14.7]

Notes: Binge drinking is defined as four or more drinks on at least one occasion (about 2 hours) in the past 30 days; heavy alcohol use is defined as four or more drinks on the same occasion (about 2 hours) on 5 or more days in the past 30 days. CI = confidence interval; µ₁₁ = prevalence of binge drinking or heavy alcohol use among non-Hispanic Black sexual minority women adjusted for age; µ₁₀ = prevalence of binge drinking or heavy alcohol use among non-Hispanic Black non-sexual minority women adjusted for age; µ₀₁ = prevalence of binge drinking or heavy alcohol use among White sexual minority women adjusted for age; µ₀₀ = prevalence of binge drinking or heavy alcohol use among White non–sexual minority women adjusted for age.
