Abstract

ObjectivesTo assess the prevalence and correlated factors of HIV-1 among Chinese and Vietnamese female sex workers (FSW) in the border county of Hekou, Yunnan province, China.MethodsA cross-sectional survey was conducted collecting information on demographics, sexual behavior, medical history, and drug use. Blood samples were obtained to test for HIV/STIs. Multivariate logistic regression model was used to examine associations between factors and HIV-1 infection.ResultsOf 345 FSWs who participated in this study, 112 (32.5%) were Chinese and 233 (67.5) were Vietnamese. Vietnamese FSWs were significantly more likely to be HIV-1 positive (7.7%) compared with Chinese FSWs (0.9%) (p = 0.009). In multivariate analysis, sexual debut at age≤16 (OR 3.8: 95% CI: 1.4, 10.6), last client’s payment <150 RMB ($22 USD) (OR: 5.2, 95% CI; 1.7, 16.6), and HSV-2 (OR: 12.3; 95% CI: 1.6, 94.8) were significant for HIV-1 infection.ConclusionsDifferences in HIV prevalence in Vietnamese and Chinese FSWs may be indicative of differential risk. It is important to characterize the nature of trans-border transmission in order to gain a better understanding of the potential impact on the international HIV epidemic. Understanding the correlated factors for HIV in Vietnamese and Chinese FSWs is important for designing interventions for this vulnerable population.

Highlights

It is recognised that cross-border sex workers have high rates of both HIV/STD prevalence and incidence, and that they play an important role in transmitting HIV across national borders.Thomas L. et al[1]. concluded that HIV prevalence was as high as 6% among female sex workers (FSWs) in two large cities on the US-Mexico border

Summary

Introduction

It is recognised that cross-border sex workers have high rates of both HIV/STD prevalence and incidence, and that they play an important role in transmitting HIV across national borders.Thomas L. et al[1]. concluded that HIV prevalence was as high as 6% among female sex workers (FSWs) in two large cities on the US-Mexico border. Concluded that HIV prevalence was as high as 6% among female sex workers (FSWs) in two large cities on the US-Mexico border. Another survey[2] in the U.S.Mexico border region from 2003–2006 concluded that 80% of 4,279 cases of HIV infection were transmitted through sexual contacts, including MSM and high-risk heterosexual contacts. A study conducted in the five border provinces of Vietnam concluded the prevalence of HIV among FSWs was 4.5% in these areas[4]. A systematic review of the studies conducted on the Indo- Nepal Border concluded that high prevalence of HIV was associated with male labour migrants and commercial sex at the border area[12]
