Each row variable in the table served as the dependent variable in a multivariable model that included MSMO/MSMW group and significant (p<0.05) covariates (eg, age, number of partners in the last year, sexual orientation, race/ethnicity, relationship status, ever been homeless, ever used alcohol, ever used marijuana, ever used drugs other than marijuana, ever in ected drugs, ever received money in exchange for sex, ever had sex without a condom, ever had unprotected receptive anal sex, ever had protected receptive anal sex, ever had an STI and ever tested for HIV). Only the OR associated with the MSMO/MSMW group in each model, with MSMW as the reference group, is shown.
Because of the small numbers of MSMO and MSMW who did not return for their HIV test results or whose results were indeterminate, only those respondents with a self-reported result of HIV positive or HIV negative were included in the adjusted model.
MSMO, men who have sex with men only; MSMW, men who have sex with men and women; STI, sexually transmitted infection.
