HIV prevention among street-based sex workers (SSWs) in Chongqing, China: interviews with SSWs, clients and healthcare providers

Differences in socio-demographics status, risk behaviours, healthcare uptake and HIV/ sexually transmitted infections (STIs) between brothel-based and street-based female sex workers in Yunnan, China

BACKGROUND

Heterosexual contact is the primary mode of HIV transmission in China and commercial sex is thought to play a crucial role in China's epidemic. Female sex workers (FSWs) in China tend to be either brothel-based (BSWs) or street-based (SSWs), but few studies have investigated the differences between these important segments of this difficult-to-reach, high-risk population. Our aim was to explore the differences between SSWs and BSWs in terms of socio-demographic characteristics, sexual and risky practices, HIV/STI-related knowledge, health services, HIV/STI prevalence and other aspects.

METHODS

A cross-sectional survey was conducted in Yunnan Province of China in partnership with a local FSW-friendly non-governmental organization. Face-to-face interviews using a structured questionnaire were conducted to collect data on socio-demographic characteristics, sex work history, sexual behaviours, HIV/STI-related knowledge, HIV testing history, and healthcare services uptake. Blood samples were taken for HIV and syphilis testing, and urine samples for gonorrhea and chlamydia testing. Descriptive statistics were used to evaluate differences between SSWs and BSWs.

RESULTS

A total of 185 BSWs and 129 SSWs were included in the study. SSWs were older and less educated, had more dependents and more clients, lower condom use and accessed fewer healthcare services. Moreover, 37.2% of SSWs and 24.9% of BSWs were found to have HIV/STI infection. Unfortunately, the awareness related to STIs was relatively low in both groups, especially SSWs.

CONCLUSIONS

Our study provides evidence that confirms the disproportionately high vulnerability of SSWs to HIV and other STIs, underscoring the urgent need for the Chinese health and public health sectors to prioritize outreach to SSWs. Awareness and educational programs, condom distribution, testing and health check-ups should be included in a comprehensive strategy for HIV/STI prevention in this high-risk population.

Differential Burden of HIV Among Adolescent Girls and Young Women by Places Associated With Sex Work: An Observational Study in Mombasa, Kenya

BACKGROUND

The design of HIV prevention programs for adolescent girls and young women (AGYW) are informed by data on who is at highest risk and where they can be reached. Places (hotspots) associated with selling sex are an established outreach strategy for sex work (SW) programs but could be used to reach other AGYW at high risk.

SETTING

This study took place in Mombasa, Kenya.

METHODS

We conducted a cross-sectional, bio-behavioural survey among (N = 1193) sexually active AGYW aged 14-24 years recruited at hotspots. We compared HIV prevalence by subgroup (SW; transactional sex, TS; and non-transactional sex), stratified by hotspot type (venues and nonvenues). We examined whether associations between HIV prevalence and hotspot/subgroup remained after adjustment for individual-level risk factors, and estimated HIV prevalence ratio with and without adjustment for these individual-level factors.

RESULTS

Overall HIV prevalence was 5.6%, 5.3% in venues and 7.3% in nonvenues. Overall SW HIV prevalence was 2-fold higher than among participants engaged in nontransactional sex. After adjusting for age and individual-level risk factors, HIV prevalence was 2.72 times higher among venue-based SWs (95% confidence interval: 1.56 to 4.85) and 2.11 times higher among nonvenue AGYW not engaged in SW (95% confidence interval: 0.97 to 4.30) compared with venue-based AGYW not engaged in SW.

CONCLUSION

AGYW who sell sex remain at high risk of HIV across types of hotspots. The residual pattern of elevated HIV burden by AGWY subgroup and hotspot type suggests that unmeasured, network-level factors underscore differential risks. As such, hotspots constitute a "place" to reach AGYW at high risk of HIV.

Prevalence, Trends and Correlates of HIV, Syphilis and HCV Infection Among Chinese Local and Cross-border Migrant Female Sex Workers in the Sino-Vietnam Border Area of Guangxi, 2016-2021

Female sex workers (FSWs) are considered a high-risk group for sexually transmitted infections (STIs). However, limited data exist on the prevalence and trends of HIV, syphilis and HCV among FSWs in the Sino-Vietnam border area. To determine the prevalence, trends and correlates of STIs among Chinese local FSWs (CL-FSWs) and cross-border migrant FSWs (CM-FSWs), we conducted consecutive cross-sectional surveys from 2016 to 2021, recruiting 7747 CL-FSWs and 932 CM-FSWs. The overall HIV, syphilis and HCV prevalence declined from 1.0%, 8.8% and 1.7% to 0.1%, 0.9% and 0.3%, respectively. There was no significant downward trend in the overall HIV and syphilis prevalence. However, HCV prevalence showed a decreasing trend among CL-FSWs. CM-FSWs had higher HIV prevalence (2.5% vs. 0.6%). Similarities and differences in STIs-related factors existed between CM-FSWs and CL-FSWs. For instance, receiving HIV-related services in the last year reduced the risk of HIV infection (for CM-FSWs: aOR = 0.234, 95% CI: 0.055-0.993; for CL-FSWs: aOR = 0.182, 95% CI: 0.058-0.567). Serving male clients at least 50 years old increased the risk of syphilis infection (for CM-FSWs: aOR = 4.277, 95% CI: 1.535-11.917; for CL-FSWs: aOR = 1.404, 95% CI: 1.087-1.815). Moreover, CM-FSWs with past-year STIs history had a higher risk of HIV (aOR = 34.976, 95% CI: 5.338-229.176) and HCV infection (aOR = 17.649, 95% CI: 1.846-168.846), both of which were associated with multiple factors in CL-FSWs. It is therefore necessary to develop effective, accessible, high-quality and targeted interventions for CM-FSWs and CL-FSWs.

HIV knowledge, self-perception of HIV risk, and sexual risk behaviors among male Tajik labor migrants who inject drugs in Moscow

BACKGROUND

The interplay of human immunodeficiency virus (HIV) knowledge and self-perception of risk for HIV among people who inject drugs is complex and understudied, especially among temporary migrant workers who inject drugs (MWID) while in a host country. In Russia, Tajik migrants make up the largest proportion of Moscow's foreign labor. Yet, HIV knowledge and self-perceived risk in association with sexual risk behavior among male Tajik MWID in Moscow remains unknown.

OBJECTIVE

This research examines knowledge about HIV transmission, self-perception of HIV risk, and key psychosocial factors that possibly contribute to sexual risk behaviors among male Tajik labor MWID living in Moscow.

METHODS

Structured interviews were conducted with 420 male Tajik labor MWID. Modified Poisson regression models investigated possible associations between major risk factors and HIV sexual risk behavior.

RESULTS

Of the 420 MWID, 255 men (61%) reported sexual activity in the last 30 days. Level of HIV knowledge was not associated in either direction with condom use or risky sexual partnering, as measured by sex with multiple partners or female sex workers (FSW). Lower self-perceived HIV risk was associated with a greater likelihood of sex with multiple partners (aPR: 1.79, 95% CI: 1.34, 2.40) and FSW (aPR: 1.28, 95% CI: 1.04, 1.59), but was not associated with condom use. Police-enacted stigma was associated with sex with multiple partners (aPR: 1.22, 95% CI: 1.01, 1.49) and FSW (aPR: 1.32, 95% CI: 1.13, 1.54). While depression and lower levels of loneliness were associated with condomless sex (aPR: 1.14, 95% CI: 1.05, 1.24; aPR: 0.79, 95% CI: 0.68, 0.92, respectively), only depression was associated with condomless sex with FSW (aPR: 1.26, 95% CI: 1.03, 1.54).

CONCLUSIONS

HIV prevention programing for male Tajik MWID must go beyond solely educating about factors associated with HIV transmission to include increased awareness of personal risk based on engaging in these behaviors. Additionally, psychological services to counter depression and police-enacted stigma are needed.

A Confounding Discourse Analysis of Vietnamese Sex Workers' Talk in the City of Kaiyuan, China

BACKGROUND

Vietnamese female sex workers (VFSWs) cross the border into Kaiyuan City, Yunnan Province yearly. However, very little is known about both the health and psychological issues VFSWs experience. The objectives of this study were to explore the dominant discourses that emerged from the VFSWs' talk. The interviews occurred between May 2018 and June 2018 with 20 VFSWs who worked in Kaiyuan City, China. The English translated transcripts were analyzed using an eclectic feminist method of discourse analysis. Two discourses emerged. First, "Agency when working in Karaoke Bars and other Indoor Venues", and second, "Negative Impacts on Psychological Well-being and Other Problems from Migration." As for Discourse 1, the VFSWs positioned themselves as having agency over choosing their clientele as well as agency over what they were willing to negotiate with their clients to establish boundaries of their bodies. As for the Discourse 2, while there was a discourse of agency in their work there was also a contrasting, confounding discourse around the negative impact on psychological well-being and reports of stress as a migrant worker. Discourse 1 and Discourse 2 are confounding. When analyzed together, the discourses suggest that the impacts on psychological well-being may be more related to the migrant status of the women, supporting the notion of systemically influenced agency.

Client-Perpetrated Violence Experience Among Female Sex Worker in Guangdong, South China: Results from a Cross-Sectional Study

Client-perpetrated violence (CPV) can lead to worse health consequences. However, little attention is paid to the CPV experience among Chinese female sex workers. Our study aimed to assess the association between CPV experience and health risk behaviors among FSWs in China. Data used in this study was from the baseline interviewer-administered questionnaire of a cluster randomized controlled trial conducted in June-October 2020. The collected information included sociodemographic characteristics, HIV/STI symptoms, number of clients, quality of the workplace, and past CPV experience. The association between violence experience and potential HIV/STI risk factors was explored using multivariable regression. Among 480 FSWs who participated in this study, 13.5% experienced CPV in the past. Compared to those who had never experienced CPV, FSWs who experienced CPV were more likely to report previous STI-related symptoms (aOR 4.29, 95% CI 1.73-10.64), more than 15 clients in the past month (aOR 2.56, 95% CI 1.18-5.52), a history of HIV testing (aOR 2.99, 95% CI 1.64-5.46), and work at low-tier workplaces (aOR 2.09, 95% CI 1.18-3.70). Overall, CPV prevalence is not low among Chinese FSWs, and there are some associations with HIV/STI risk factors; a future intervention targeting CPV in HIV/STI prevention programs is needed.

Access to HIV-prevention in female sex workers in Ukraine between 2009 and 2017: Coverage, barriers and facilitators

The provision of comprehensive prevention services is vital for reducing the high burden of HIV amongst Ukrainian female sex workers (FSWs). To identify barriers and facilitators that influence access to HIV prevention amongst this population between 2009 and 2017, we developed a literature-informed conceptual framework and conducted a document analysis to identify the components of the Ukrainian prevention package (PP). Using the Integrated Bio Behavioural Surveillance Surveys, we then conducted descriptive analyses to explore PP coverage from 2009 to 2017 and the influence of factors, identified by our conceptual framework. After increasing over four years, a drop in PP coverage was observed from 2013 onwards. Being a client of a non-governmental organisation, street and highway solicitation, non-condom use, and knowledge of HIV may influence access to HIV prevention in the Ukrainian context. Future interventions should consider barriers and facilitators to HIV prevention and the multiple structural levels on which they operate.

A thematic analysis of experiences of HIV risks among female sex workers in the Yunnan-Vietnam Chinese border region

Background

The Yunnan province is located near the “Golden Triangle” border region between China, Myanmar and Thailand, which has the highest HIV/AIDS prevalence in China. Female sex workers (FSWs) in the Yunnan province are highly vulnerable to HIV infection. The objective of this study was to examine the experiences of FSWs in the Yunnan to better understand the risk of infection and the potential for transmission of HIV.

Methods

Semi-structured interviews were conducted between May 2018 and June 2018 with 20 FSWs recruited in Hekou County, Yunnan Province, China. Thematic analysis was conducted to identify themes that highlighted increased exposure of FSWs to the risk of HIV infection and transmission.

Results

The findings showed that FSWs’ primary source for HIV information was gynecologists, with few visiting the local HIV charity Red Ribbon. FSWs reported infrequent visits for check-ups with some seeing a gynecologist once a year. FSWs felt that the onus was on them to prevent STI/HIV infection by using a condom during sex, regardless of their ability to negotiate use. FSWs were also reluctant to see a gynecologists for treatment. Instead, they resorted to douching as a way of preventing HIV/STIs and treating vaginal health problems, such as leucorrhea. Most FSWs worked without the influence of alcohol and drugs. A small number of FSWs reported heroin addiction and injecting drug use.

Conclusion

The findings suggest a need for innovative HIV prevention strategies among FSWs and their clients in the Chinese border region. Governmental agencies should continue to implement practical strategies in terms of HIV prevention education and condom use through tailored interventions that are localized. Such strategies should include localized tailored interventions that dispel myths about douching as a method of HIV/STI prevention and incorporate a mobile outreach approach, similar to the ‘roadside restaurant’ outreach that has been successful in rural China.

Changing trends of HIV, syphilis, HCV infections and behavioural factors among female sex workers in Chongqing, China: findings from six serial surveillance surveys

OBJECTIVES

To explore the prevalence and changing trends of HIV, syphilis, hepatitis C virus (HCV) infections and risk behaviours among female sex workers (FSWs) and to provide reference and theoretical basis for formulating targeted interventions.

DESIGN

Six consecutive cross-sectional surveys.

SETTING

Chongqing, China.

PARTICIPANTS

FSWs were included if they (1) were aged ≥16 years, (2) provided commercial sex for money or goods during the previous month and (3) were willing to participate in the survey and could provide verbal informed consent. This study included 16 791 of 16 810 participants recruited between 2013 and 2018.

PRIMARY AND SECONDARY OUTCOME MEASURES

The prevalence of HIV/syphilis/HCV infection.

RESULTS

The HIV and HCV prevalence among FSWs in Chongqing was stable during the study period, but the prevalence of syphilis had an increasing trend, particularly among low-tier and middle-tier FSWs. Improvements in HIV-related knowledge, condom use, injecting drug use and participation in HIV-related services were observed. However, no change was found in the prevalence of drug use. HIV infection was correlated with no condom use in the last commercial sex (adjusted OR (aOR) 3.48, 95% CI 1.90 to 6.37) and syphilis infection (aOR 4.88, 95% CI 1.95 to 12.18). Syphilis infection was correlated with inconsistent condom use (aOR 1.30, 95% CI 1.02 to 1.65), HIV infection (aOR 5.88, 95% CI 2.40 to 14.41), HCV infection (aOR 7.68, 95% CI 4.37 to 13.49) and sexually transmitted infection (STI) diagnosis in the past year (aOR 3.81, 95% CI 2.40 to 6.03). HCV infection was associated with injecting drug use (aOR 8.91, 95% CI 4.45 to 17.86) and syphilis infection (aOR 7.88, 95% CI 4.49 to 13.83).

CONCLUSIONS

Comprehensive interventions targeting FSWs, particularly low-tier and middle-tier FSWs, should be increasingly implemented to prevent and control HIV, syphilis and other STIs.

Mitigating circumstances: A model-based analysis of associations between risk environment and infrequent condom use among Chinese street-based sex workers

Background

Little is known about how freelance street-based sex workers navigate condom use while soliciting. Traditional behavioural model may fail to account for the complex risk environment that most street-based sex workers work within. We examine first the association of self-efficacy and the infrequent condom use, then we investigated the roles of clients and venues frequented on this association.

Method

Using a purposive chain-referral sampling method, we surveyed 248 street-based sex workers in Shanghai. The survey focused on sex workers HIV risk factors, sex work patterns, HIV knowledge, and related HIV self-efficacy. Clients types and behaviours, and characteristics of the venues frequented by these commercial sex workers were also collected. We conducted a series of multiple logistic regression models to explore how the association between a sex worker’s self-efficacy with infrequent condom use change as client and venue characteristics were added to the models.

Results

We find that within the basic model, low self-efficacy was marginally associated with infrequent condom use (54.9% vs. 45.1%, AOR = 1.70, 95% CI = 0.95–3.03). As client- and venue- characteristics were added, the associations between self-efficacy and condom use were strengthened (AOR = 2.10 95% CI = 1.12–3.91 and 2.54 95% CI = 1.24–5.19 respectively). Those who reported middle-tiered income were more likely to report infrequent condom use compared to their peers of high income (AOR = 3.92 95% CI = 1.32–11.70) whereas such difference was not found between low income and high income sex workers. Visiting multiple venues and having migrant workers as clients were also associated with infrequent condom use.

Conclusion

Our findings suggest sex worker’s self-efficacy matters in their HIV risk behaviours only when environment characteristics were adjusted. Risk environment for street-based sex workers are complex. Programming addressing behavioural changes among female sex workers should adopt holistic, multilevel models with the consideration of risk environments.
