Estimated prevalence of T. vaginalis (TV) and odds ratios by gender and sexual behaviors.

aOdds ratios (ORs) calculated using logistic regression. Gender-specific adjusted ORs (AORs) calculated from multivariable models controlling for race (Black; Non-Black), age (4 categories: 15–19, 20–24, 25–29, 30–35), and marital status (married vs. not married, including widowed, divorced, and separated). Gender Interaction tests equivalence of unadjusted ORs for males and females (i.e., logistic regression models odds of Tv as a function of Female, Behavioral variable, and Female-by-Behavioral variable).
bReferent group includes respondents who reported solely either male or female lifetime sexual partners. Respondents with no lifetime partners recoded as ‘no’.
cReferent group includes respondents reporting less than 2 partners in the past year. Respondents with no lifetime partners recoded to no partners last year. (5 respondents tested positive for TV but reported zero lifetime partners.)
dRespondents reporting no lifetime partners or no partners in the past year recoded to no new partners in the past 3 months.
eReferent group includes respondents who reported knowing whether or not their partner(s) in the past year had an STI. Respondents with no lifetime partners or no partners in the past year recoded as “knowing”.
fReferent group includes respondents who reported never being forced to have sex with someone when they didn't want to. Respondents with no lifetime partners recoded as never having forced sex.
gRespondents with no lifetime partners recoded as never having partners who were incarcerated.
hORs not calculated because none of the 32 men who reported forced sex also tested positive for Tv.
