Objective: Epidemiology of sexually transmitted infections (STIs) is largely based on surveillance data. The aim of the present study was to examine the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infections and risk factors for these infections among young women in Novosibirsk, Western Siberia.

Methods: Female university students were invited to undergo free gynecological examination. One hundred students (mean age 20.6 years, range 16–24) voluntarily participated in the study. After a confidential interview, a gynecologic examination was performed with collection of endocervical specimens. A nucleic acid amplification method (APTIMA Combo 2 assay, Gen-Probe Inc, USA) was used for N. gonorrhoeae and C. trachomatis testing.

Results: The prevalence of C. trachomatis infection was 12.0%, and N. gonorrhoeae prevalence was 2.0%. Both N. gonorrhoeae-positive females were also infected with C. trachomatis. Infected women reported younger age at first sexual intercourse (16.1 years vs 17.5 years among non-infected, p = 0.01) and a higher number of lifetime sexual partners (6.1 vs 2.8, p = 0.01). Other variables (age, new sexual partner, condom use, history of STDs etc.) did not differ between infected and non-infected subjects. Among reported symptoms, vaginal discharge (p = 0.04) and intensive menstrual bleeding (p = 0.04) were more frequent in infected women, whereas dysmenorrhea, genital pruritus, burning, pain, and dyspareunia were not.

Conclusion: The prevalence rates of C. trachomatis and N. gonorrhoeae infections in young females in Novosibirsk, Russia are higher than those previously published, possibly due to higher sensitivity of the method used in our study. As in other populations, age at first intercourse and the number of lifetime sexual partners had a significant effect on the risk of bacterial STIs.
