MTF, male-to-female transgender; FTM, female-to-male transgender. Sex-gender congruence refers to the concordance between biological sex and gender identity. Thus, MTF are biologically male and identify as women; FTM are biologically female and identify as men. Chi-square analyses were computed for reported drinking in the past two weeks; ANCOVAs were applied to mean drinking occasions (total days consuming at least one drink) and quantities (total drinks in the past two weeks and maximum number of drinks on any single day in the past two weeks) using age and race/ethnicity as covariates. Significant mean differences between groups are footnoted as follows:

total males - total females,

cisgender - transgender,

cisgender males - cisgender females,

transgender MTFs - transgender FTMs,

cisgender males - transgender MTFs,

cisgender males - transgender FTMs,

cisgender females - transgender MTFs.
