AOR from logistic regression models with statistical adjustment for age, race, grade, whether participants were U.S. born, and percent free school lunch as a proxy of socioeconomic status. For each outcome, an information-theoretic complexity-penalized model goodness-of-fit criterion for clustered survey data was used to select between two models, one specified with only main effects for the binary ARA and sexual minority status indicators (results in top half of table), the other model specified to permit effect modification (interaction) among these two explanatory factors (results in bottom half of table). For the “interaction” models, AOR for combinations of ARA and sexual minority status are reported with respect to the reference category of heterosexual girls without exposure to ARA.

AOR = adjusted odds ratio; ARA = adolescent relationship abuse; CI = confidence interval; SM, sexual minority; STI, sexually transmitted infection.

^aAdditionally adjusted for sexual minority status.
