Objectives. We sought to determine the prevalence of and risk factors associated with Mycoplasma genitalium infection in a nationally representative sample of young adults in the United States.
Methods. Urine specimens from 1714 women and 1218 men who participated in Wave III of the National Longitudinal Study of Adolescent Health (N=14322) were tested for M genitalium. Poststratification sampling weights were used to generate nationally representative estimates.
Results. The prevalence of M genitalium was 1.0% compared with 0.4%, 4.2%, and 2.3% for gonococcal, chlamydial, and trichomonal infections, respectively. No M genitaliumpositive individuals reported symptoms of discharge. M genitalium prevalence among those who reported vaginal intercourse was 1.1% compared with 0.05% among those who did not. In multivariate analyses, M genitalium prevalence was 11 times higher among respondents who reported living with a sexual partner, 7 times higher among Blacks, and 4 times higher among those who used condoms during their last vaginal intercourse. Prevalence of M genitalium increased by 10% for each additional sexual partner.
Conclusions. M genitalium was more prevalent than Neisseria gonorrhoeae but less prevalent than Chlamydia trachomatis, and it was strongly associated with sexual activity.
