Abstract

Objective: Female sex workers (FSWs) are at high risk of human papillomavirus (HPV) infections and cervical cancer due to their high number of sexual partners. The objectives of this study were to determine the prevalence of HPV and identify risk factors for high-risk HPV infection among FSWs in Hanoi and Ho Chi Minh City (HCMC), Viet Nam.

Methods: A cross-sectional study was conducted in Hanoi and HCMC between December 2017 and May 2018. We surveyed and screened 699 FSWs aged ³18 years for HPV infection and abnormal cytology. A multivariable modified Cox regression model was used to determine risk factors for high-risk HPV infection.

Results: The overall prevalence of any HPV, high-risk HPV and HPV-16/18 infection in the 699 FSWs was 26.3%, 17.6% and 4.0%, respectively, and were similar in both cities. Multiple infections were identified in 127 participants (69.0%). HPV-52 was the most prevalent (7%), followed by HPV-58 (6%). Abnormal cytology was detected in 91 participants (13.0%). FSWs who are divorced (adjusted prevalence ratio [aPR]: 1.96, 95% confidence interval [CI]: 1.01-3.81), widowed (aPR: 3.26, 95% CI: 1.49-7.12) or living alone (aPR: 1.85, 95% CI: 1.01-3.39) were associated with a higher prevalence of high-risk HPV infection.

Discussion: Almost one in five FSWs in Viet Nam are infected with high-risk HPV. This highlights the importance of prevention strategies such as HPV vaccination and screening in this high-risk group.

越南河内和胡志明市女性性工作者中人乳头瘤病毒感染的流行率和危险因素:一项横断面研究。

目的:女性性工作者(FSWs)由于性伴侣数量多，感染人乳头瘤病毒(HPV)和宫颈癌的风险高。本研究的目的是确定越南河内和胡志明市(HCMC)女工中HPV的流行情况，并确定高危HPV感染的危险因素。方法:2017年12月至2018年5月在河内市和胡志明市进行横断面研究。我们调查并筛选了699名318岁的FSWs HPV感染和细胞学异常。采用多变量修正Cox回归模型确定高危HPV感染的危险因素。结果:699名妇女HPV、高危HPV和HPV-16/18的总体感染率分别为26.3%、17.6%和4.0%，两市差异无统计学意义。127名参与者(69.0%)发现多重感染。HPV-52最常见(7%)，其次是HPV-58(6%)。91名参与者(13.0%)检测到细胞学异常。离婚(调整患病率比[aPR]: 1.96, 95%可信区间[CI]: 1.01-3.81)、丧偶(aPR: 3.26, 95% CI: 1.49-7.12)或独居(aPR: 1.85, 95% CI: 1.01-3.39)的FSWs与高危HPV感染的较高患病率相关。讨论:越南几乎五分之一的女服务员感染了高危HPV。这突出了预防策略的重要性，如在这一高危人群中接种HPV疫苗和筛查。
