In the National Longitudinal Study of Adolescent Health Study, significant differences in the prevalence of trichomoniasis among adolescents were noted by race: white, 1.2%; Asian, 1.8%; Latino, 2.1%; Native American, 4.1%; and African American, 6.9%. [37] Considerable differences were also observed in the national NHANES 2001-2004 study conducted among women ages 14-49: non-Hispanic whites, 1.2%; Mexican Americans, 1.5%; and non-Hispanic blacks, 13.5%. [38]

Evidence suggests that T vaginalis infection likely increases HIV transmission and that coinfection with HIV complicates treatment of trichomoniasis. [46] Control of T vaginalis may represent an important means of slowing HIV transmission, particularly among African Americans, in whom higher rates have been observed.

Daugherty et al screened a representative sample of men aged 18-59 years with RNA testing for T vaginalis and found that 0.49% were infected. [47]
