RESUMO
OBJECTIVES: Female sex workers (FSWs) are at high risk of sexually transmitted infections (STIs) and form a core group to facilitate STI spreading. We aimed to estimate the prevalence of STIs among FSWs who attended Female Harm Reduction Center of Isfahan, Iran, and to determine the association between risky behaviors and STIs. STUDY DESIGN: In a cross-sectional study, 99 FSWs were recruited and interviewed about demographic characteristics and risky behaviors. A trained midwife examined FSWs for genital ulcer, abnormal vaginal discharge, and cervicitis. Urine and genital specimens were collected and real-time polymerase chain reaction was performed to diagnose Neisseria gonorrhoeae, human papilloma virus (HPV), and Trichomonas Vaginalis. Data were analyzed via χ2 test and logistic regression in StataCorp software (version 11) with 95% confidence interval. RESULTS: Totally, 84.9% of FSWs reported STI symptoms, while 12.1% of them were infected with N gonorrhoeae, HPV, or T vaginalis. Human papilloma virus and gonorrhea prevalence rates were 5.7% and 8% in FSWs with STI-associated symptoms. Sexually transmitted infections showed significant association with duration of prostitution (odds ratio [OR]HPV = 1.009 [95% confidence interval [95% CI: 1.004-1.01]; ORgonorrhea = 1.01 [95% CI: 1.00-1.01]) and condom usage (ORHPV = 0.11 [95% CI: 0.012-0.98]; ORgonorrhea = 0.04 [95% CI: 0.005-0.33]). CONCLUSION: Due to the literature gap on the Iranian FSWs' sexual health and the intense stigma around this subject, in Iran, our results would be useful for developing an efficient intervention program. The prevalence of STIs in Isfahan FSWs can be controlled with programs such as consistent condom use and STI treatment. In addition, as just one-tenth of FSWs with an STI symptom were positive for an STI, symptomatic diagnosis of STIs might be insufficient.
