Estimated prevalence of T. vaginalis (Tv) and odds ratios by gender and health 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).bPrevious STI includes self-reported diagnoses of C. trachomatis, N. gonorrhea, and/or T. vaginalis.cSelf-reported previous diagnosis of T. vaginalis infection.dSelf-reported symptoms of dysuria and/or discharge.eORs not calculated because none of the 16 men with a prior diagnosis of Tv also tested positive for Tv in the survey.
