Chlamydia trachomatis, Neisseria gonorrhoeae, and Mycoplasma genitalium screening during pregnancy is not performed routinely in France. We conducted the first prospective study in 1004 women attending for routine antenatal care to determine the prevalence and risk factors for these bacterial infections. The overall prevalence of C. trachomatis, N. gonorrhoeae, and M. genitalium infections was 2.5%, 0%, and 0.8%, respectively. In patients aged 18-24 years, the prevalence increased to 7.9% for C. trachomatis and to 2.4% for M. genitalium. C. trachomatis infection was associated with age ≤24 years or being single or having more than 5 sexual partners in a lifetime. M. genitalium infection was more frequent in patients aged ≤24 years or who had a history of abortion or their first sexual intercourse after 20 years of age. The high prevalence of C. trachomatis in pregnant women aged ≤24 years, mostly asymptomatic, suggests that systematic screening could be beneficial.
