Screening of sex workers in Turkey for Chlamydia trachomatis.
BACKGROUND
Increasing migration of sex workers across East European borders into Turkey has resulted in increased arrests of unregistered sex workers. There is concern regarding the prevalence of sexually transmitted diseases (STD) such as C. trachomatis in this unregulated group.


OBJECTIVE
To measure the prevalence of C. trachomatis infection and selected related demographic and behavioral factors among registered and unregistered sex workers in Istanbul, Turkey.


METHODS
In a cross-sectional study, the prevalence of C. trachomatis infection was studied by direct fluorescent antibody testing in 248 sex workers: 158 presented for routine medical screening and 90 who were arrested for lack of registration. All subjects were interviewed regarding demographic factors, sexual activity, and antibiotic and drug use.


RESULTS
The overall C. trachomatis prevalence was 12.9% (12.0% registered and 14.4% unregistered). There was a strong association between never using condoms and chlamydia positivity (odds ratio 8.9 [95% confidence interval 3.7 to 21.6]).


CONCLUSIONS
The high rate of C. trachomatis among all tested sex workers and the lack of regular condom use, particularly among unregistered sex workers, indicate that there is an urgent need for safe sex education and continued STD screening of unregistered sex workers.
