Among all participants, sexual abuse was reported by 18.5% of the sample. Rates and frequency varied by race/ethnicity and gender (Table 3); sexual abuse was more frequently endorsed females regardless of race/ethnicity, and by American Indian participants (women: 29.6%; men: 20.0%) and less frequently endorsed by Asian Americans (women: 14.2%; men: 13.4%). Among all participants, more frequent exposure to sexual abuse was associated with AUD (OR 1.1, aOR: null), and associations did not differ significantly by race/ethnicity ( p: 0.171), gender ( p: 0.545) or race/ ethnicity × gender ( p: 0.119). Among all participants, more frequent exposure to sexual abuse was associated with CUD (OR1.1, aOR: 1.1), and associations did not differ significantly by race/ethnicity ( p: 0.864), gender ( p: 0.075), or race/ethnicity × gender ( p: 0.185). Among all participants, more frequent exposure to sexual abuse was associated with TUD (OR 1.1, aOR:1.1), and associations did not differ significantly by race/ethnicity ( p: 0.314), gender ( p: 0.187), or race/ethnicity × gender ( p: 0.627).
