Abstract

Objective: Human papillomavirus virus (HPV) is the major causative factor for cervical cancer, and sex workers are at high risk for HPV infection. In this study, we aimed to estimate the prevalence and risk factors of HPV infection among female sex workers (FSWs).

Materials and Methods: The study included 239 brothel-based FSWs who work in Izmir, Turkey. A self-administered questionnaire for risk factors was completed, and cervical brush samples were taken for HPV detection and typing. HPV detection and typing were performed by multiplex polymerase chain reaction (PCR) and reverse hybridization methods. The risk factors related to HPV infection were determined by multivariate analysis.

Results: The prevalence of HPV among FSWs was 20.1%. HPV18 was the most common type (40%), followed by HPV16 (17%) and HPV50 (15%). Logistic regression analysis revealed that being less than 30 years of age, having a high frequency of sexual contacts, smoking, and lack of condom use were significantly associated with HPV infection.

Conclusion: FSWs have a high prevalence of HPV infection and are at increased risk for cervical cancer. As they are a priority group for active follow-up, national strategies for reducing HPV among FSWs and regular cervical cancer screening programs should be implemented for this population.
