Transactional sex and the challenges to safer sexual behaviors: a study among male sex workers in Chennai,India

Male sex workers (MSW) are a significant but invisible population in India who are at risk for HIV/sexually transmitted infections (STIs). Few studies from India have documented HIV risk factors and motivations for sex work in this population. Between 2013 and 2014, a community-based convenience sample of 100 MSW in Chennai (south India) completed a baseline risk assessment as part of a behavioral intervention. Participants were ≥18 years, and reported current sex work. We report medians and proportions, and Wilcoxon–Mann–Whitney and chi-square tests are used to examine differences between sex work and sexual behavior measures by income source. Participants were engaged in sex work for 5.0 years (IQR?=?2.3–10.0), and earned 3000 (IQR?=?2000–8000) Rupees (<50 USD) per month from sex work. Sixty-four percent reported ever testing for HIV and 20.2% for any STI. The most common reasons for starting sex work were money (83.0%) and pleasure (56.0%). Compared to participants with an additional source of income, those whose only source of income was sex work reported more male clients in the past month (10.0 vs. 6.0, p?=?.017), as well as more condomless anal sex acts with male clients (8.0 vs. 5.0, p?=?.008). Nearly 70.0% were offered more money not to use a condom during sex with a client, and 74.2% reported accepting more money not to use a condom. Three-quarters reported having experienced difficulty using condoms with clients. MSW in India engage in high levels of sexual risk for HIV/STIs. Money appears to be a driving factor for engaging in sex work and condomless sex with clients. HIV prevention interventions with MSW should focus on facilitating skills that will support their ability to negotiate sexual safety in the context of monetary disincentives.     

Factors Associated with HIV Testing,Condom Use,and Sexually Transmitted Infections Among Female Sex Workers in Nha Trang,Vietnam

This study examined predictors of HIV testing, successful condom negotiation with clients, and self-reported sexually transmitted infections (STIs) among Vietnamese female sex workers (FSW). Data were collected by using face-to-face interviews from a community sample of 610 FSW from Nha Trang city during October–December, 2000. Having had an HIV test was associated with having spent time in a rehabilitation center. Consistently successful negotiation of condom use occurred most among FSW who had few clients, understood how HIV was not transmitted, and had not reported ever having any symptoms of STIs. Migration to Nha Trang for sex work was a risk factor for an STI diagnosis; successful negotiation of condom use had a protective effect. Our results suggest the need for voluntary HIV counseling and testing, further promotion of condom use among FSW populations, and better use of rehabilitation sites to promote HIV prevention.     

Knowledge, risk perceptions and condom usage in male sex workers from three Australian cities

The study identifies factors associated with knowledge and perception of risk of HIV/AIDS, as well as attitudes to and usage of condoms by a sample of male sex workers (MSW). One hundred and eighty-five male sex workers completed a self-reported questionnaire, including knowledge about HIV transmission, attitudes to condom use and perceptions and personal susceptibility to HIV and sexually transmitted infection (STI) risk, and a two-week diary recording use of condom during commercial sex encounters. The findings reveal that condom use was found in 77.7% of the encounters with clients and the majority of the respondents perceived themselves to be at no risk for HIV because of sex work. Independent sex workers from Melbourne and workers who owned their place of residence used condoms in a significant lower proportion. Generally speaking, knowledge about the risks associated with AIDS was high, with respondents showing lower knowledge about the risks associated with unprotected receptive or active oral sex. Participants held a positive attitude to condom use; most considered the provisions of condoms to be their responsibility rather than clients; and they were more worried about contracting an STI than HIV. Those who scored higher on the knowledge scale had more positive attitudes to condom use and those who had a more positive attitude to condom use recorded a perceived lower risk of contracting STI but not HIV. The study discusses the relevance of these findings for public health risk reduction and sexual health education campaigns.     

Indicators of Mobility,Socio-Economic Vulnerabilities and HIV Risk Behaviours Among Mobile Female Sex Workers in India

This paper examines the relationship between indicators of mobility, socio-economic vulnerabilities, and HIV risk behaviours among 5,498 mobile female sex workers (FSWs) living in the four high HIV prevalence states in India. Female sex workers with greater degree of mobility reported significantly more often than the FSWs with lesser degree of mobility that they experienced physical violence, and consumed alcohol prior to sex. Further, FSWs with greater degree of mobility reported significantly more often than the FSWs with lesser degree of mobility that they had inconsistent condom use in sex with clients, even after controlling for several demographic characteristics and socio-economic vulnerabilities including experiences of violence. Additionally, short duration visits and visit to the Jatra (religious fairs) places found to have significant association with their inconsistent condom use in sex with clients as well as continuation of sex despite having STI symptoms. These findings suggest the need for screening FSWs for higher degree of mobility and to mobilize them to form community networks so as to deal with violence, reduce alcohol use and promote consistent condom use along the routes of mobility. HIV prevention interventions aimed at FSWs require an increased attention to address the socio-economic vulnerabilities including alcohol use, with particular emphasis on those FSWs who are on the move in India and elsewhere.     

Correlates of HIV Risk and Preventive Behaviors in Armenian Female Sex Workers

This study describes HIV risk and preventive behaviors and their correlates among Armenian female commercial sex workers (CSWs) as a prerequisite to developing gender and culturally appropriate interventions. Ninety-eight CSWs from three Armenian cities were interviewed using a structured questionnaire. Quantitative findings were further elaborated by focus group discussions (N = 25) and key informant interviews (N = 8). Inconsistent condom use with all types of sexual partners was reported, as were condom tear/slippage, alcohol and drug use, and sex with drug injecting clients. Prominent misconceptions regarding HIV transmission, prevention and disease manifestations were noted. Correlates of condom use intentions included history of substance use, attitudes regarding condom use, risk perception, and comfort negotiating condom use. Intentions to use condoms were strongly associated with recent frequency of condom use. Understanding the relationship between condom use and its determinants is critical in the design and implementation of effective prevention programs tailored for Armenian CSWs.     

Determinants of condom use in female sex workers in Surabaya, Indonesia

In the developing world condom use among sex workers and their clients plays a dominant role in the transmission of HIV/STD. In Surabaya, Indonesia, data from the 1993 STD prevalence survey in female sex workers (brothels, street, massage parlours, barber shops, call-girl houses, and nightclubs) reveal that only 5% (33/692) of the brothel workers and 14% (25/177) of the street walkers had condoms in their possession at the time of the interview. During the last paid sexual intercourse, sex workers from the brothels, streets, and nightclubs used condoms infrequently (14%, 20%, and 25%, respectively). Sex workers from massage parlours, barber shops, and call girls were about 5 to 3 times more likely to use condoms than sex workers from nightclubs (adjusted odds ratio of 3.5, 4.9, and 4.2, respectively); thus condom promotion programmes should be targeted at sex workers at brothels, streets, and nightclubs. Programmes should include: (1) free distribution of condoms to sex establishments at the initial stage, and condom social marketing at later stages; (2) penalties, including legal sanctions, against any sex establishments that do not consistently use condoms; (3) participation of brothel owners and madams in encouraging sex workers to consistently have clients use condoms during sexual intercourse; and (4) establishment of sentinel surveillance to monitor STD/HIV and condom-use compliance.     

The Potential for Rapid Sexual Transmission of HIV in China: Sexually Transmitted Diseases and Condom Failure Highly Prevalent Among Female Sex Workers

Commercial sex is believed to play a role in the steadily increasing heterosexual transmission of HIV in China, but little attention has been paid to female sex workers working in the entertainment industry. From October to December 2000, we conducted a cross-sectional survey of 482 women in Baise City, Guangxi Autonomous Region, bordering Yunnan Province. Although no participants had antibodies to HIV infection, 4% of study participants tested positive for markers for syphilis and 21% reported being diagnosed with sexually transmitted diseases in the past year. Women reported low rates of consistent condom use with customers (17%), a spouse or fiancé (9%), and casual partners (13%). A substantial proportion experienced condom failure (20% slippage and 13% breakage). Multivariate analyses found that consistent condom use with customers was related to multiple sexual partnerships, higher condom knowledge, and higher condom-use negotiation skills. Multiple sexual partnerships and higher condom-use negotiation skills predicted consistent condom use with casual partners, whereas higher condom-use negotiation skills did so for consistent condom use with a spouse or fiancé. Our data suggest the need for condom education, condom skills training, and the distribution of reliable condoms among female sex workers. HIV prevention efforts must target these women as well as their clients and sex partners to prevent the further spread of HIV to the general population in China.     

Clients of Female Sex Workers as a Bridging Population in Vietnam

Understanding bridging behaviors of clients of female sex workers (FSWs) is important for projecting and intervening in the spread of sexually transmitted infections in Vietnam. The goals of the study were to determine HIV/STI prevalence amongst different bridging groups, identify factors associated with being potential and active bridgers, and assess the association of drug use and unsafe sex with HIV and/or STI prevalence. In April, 2007, 292 clients were anonymously interviewed at sex venues in a two-stage time-location cluster sampling survey, followed by HIV, syphilis, and HSV-2 testing. Based on condom use with both high-risk (FSWs) and low-risk (wives/girlfriends) sexual partners, clients were classified as unlikely, potential, or active bridgers. The majority of clients were potential or active bridgers (55.8%) who had a significantly higher prevalence of herpes simplex type 2 (HSV-2) (21% and 33%, respectively) than unlikely bridgers (8.7%). HIV seropositivity was 4.4-fold (95% CI 1.1-17.1) higher among those who were HSV-2-positive. Clients of FSWs may be playing a major bridging role in transmitting HIV and sexually transmitted infections (STIs) in Vietnam. An observed synergistic interaction between drug use and condom slippage/breakage emphasizes the importance of proper condom use, particularly among drug users.     

Sexually transmitted infections and sexual behaviour among youth clients of hotel-based female sex workers in Dhaka, Bangladesh

A cross-sectional study was conducted among youth clients of hotel-based female sex workers (YCHBFSWs) in nine randomly selected hotels in Bangladesh to examine sexual-risk behaviour, condom use and determinants of condom use in last sex, knowledge of HIV, sexually transmitted infection (STI) prevalence and STI care-seeking behaviour. A prestructured questionnaire was used to collect sociodemographic, behavioural, clinical information; urine specimens (before sex) and blood were collected for diagnosis of Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, syphilis and herpes simplex virus 2 (HSV2) infection. One thousand and thirteen participants were enroled in the study. Approximately half of them reported visiting female sex workers (FSWs) at least once a month and 25% visited FSWs at least once a week. Only 12% of participants reported regular condom use. The prevalence of N. gonorrhoeae, C. trachomatis, T. vaginalis, syphilis and HSV2 was 2.2%, 3.9%, 7.2%, 2.6% and 12.9%, respectively. Only 15.3% of the YCHBFSW sought STI care in the past year. Negotiation of condom use with FSWs was the main determinant (odds ratio = 17.95) for condom use at last sex. Male clients of FSWs, including YCHBFSW, are an important bridge population for HIV transmission in Bangladesh and HIV interventions should be designed and implemented for them.     

Prevalence and Correlates of Condom Use and HIV Testing Among Female Sex Workers in Tashkent,Uzbekistan: Implications for HIV Transmission

Little is known about sex work in Tashkent, Uzbekistan, despite rapid increases in HIV infection. Consistent client condom use and prior HIV testing are described among 448 female sex workers (FSW) completing a self-administered questionnaire, health provider interview, and HIV testing between April 2003 and March 2004. Participants were recruited through outreach workers using modified snowball sampling. Consistent client condom use was more likely for FSW who were married, knew condoms prevent HIV, and from countries in south Central Asia. Prior HIV testing was less likely for FSW younger than 21 years, who shared drugs with clients, initiated sex work at 18 years or less and had engaged in sex work less than 2 years. Low rates of condom use, particularly by those with risky drug behaviors, indicate that targeted risk-reduction interventions are urgently needed.     

HIV Infection,risk factors and health services use among male-to-female transgender sex workers: a cross-sectional study in Portugal

Male-to-female transgender sex workers (TSW) have been identified as a key population at risk for HIV. This study examined risk behaviors and HIV prevalence among TSW, and described health services use. A participatory cross-sectional survey was conducted with 125 TSW recruited in locations and networks where sex workers congregate. HIV-risk behaviors were common among participants. Inconsistent condom use with clients in the previous month was reported by 12.0% of participants and was associated with Portuguese nationality, inconsistent condom use with non-paying partners and not been reached by HIV prevention programs in the previous year. Ever use of psychoactive substances was reported by 61.6% of participants and was associated with being non-employed, doing full-time sex work, having higher number of non-paying partners and having never used health services. Also, ever use of psychoactive substances was negatively associated with older age and Portuguese nationality. About 34% of the participants reported having not been tested in the previous 12 months; 20.2% never used the health services. Overall, 14.9% (95%CI: 8.0–21.0%) reported being HIV-positive. Of those, 22.2% (95%CI: 1.0–43.5%) had unprotected sex with clients in the previous month, 26.7% (95%CI: 1.3–52.0%) had unprotected sex with non-paying partners in the previous year, 13.3% (95%CI: 0.0–33.0%) had ever injected drugs, 60.0% (95%CI: 23.0–97.0%) reported a past STI and 33.3% (95%CI: 2.0–64.6%) had currently HIV/STI co-infection. The socioeconomic, relational or partnering, and structural contexts conducive to increased risk are warranting further investigation. This knowledge would be valuable to inform prevention programs. HIV interventions, including secondary prevention, should address specific needs of TSW. Outreach initiatives aimed to reach TSW who are difficult to access can play a role in promoting access to health services and reducing HIV infection and transmission.     

Prevalence and Correlates of Female Condom Use and Interest Among Injection Drug-Using Female Sex Workers in Two Mexico–US Border Cities

Little is known about female condom use among female sex workers who inject drugs (FSW-IDUs) in Northern Mexico, where HIV/STI prevalence is high. We examined the prevalence and correlates of female condom use and interest in female condom use among FSW-IDUs aged?>18?years in Tijuana and Ciudad Juárez, Mexico enrolled in a behavioral intervention designed to reduce high-risk sexual and injection behaviors. Of 621 FSW-IDUs, 8?% reported ever using female condoms, and 67.2?% expressed interest in trying female condoms. Factors independently associated with female condom use were having had a client become angry at the suggestion of using condoms and having engaged in unprotected vaginal sex with non-regular clients. Factors independently associated with interest in using female condoms were lifetime physical abuse and lifetime sexual abuse. Increasing the availability of female condoms and providing education on their use in the context of drug use and violence is recommended.     

Declining sexually transmitted infections among female sex workers: the results of an HIV and sexually transmitted infection prevention strategy in Honduras, 2006-08

In 2006, we implemented an HIV and sexually transmitted infection (STI) prevention programme for female sex workers (FSWs) in three Honduran cities. All FSW attending STI clinics underwent regular examinations and STI testing. Information on condom use with different partners was collected at each visit. After three years, we detected a significant decline in the prevalence of syphilis from 2.3% at the first screening to 0.0% at the third screening (P = 0.05), and of chlamydia, from 6.1% to 3.3% (P = 0.01). No changes were observed in the prevalence of gonorrhoea or trichomoniasis. The cumulative HIV prevalence remained constant (P = 0.44). Reports of condom use with clients increased from 93.8% to 98.9% (P < 0.001). The implementation of an HIV/STI prevention programme in FSW has contributed to increases in condom use with clients and the reduction in syphilis and chlamydia prevalence. The intervention should be strengthened and considered as part of a national health policy strategy.     

Does the use of HIV testing and counseling services influence condom use among low-paid female sex workers in Guangxi,China?

HIV testing and counseling (HTC) are increasingly used in China during routine medical care visits to health facilities. However, limited data are available regarding the association between the utilization of HTC services and condom use among low-paid female sex workers (FSWs) who are at high risk of HIV infection but are hard to reach. A cross-sectional study was conducted among 794 low-paid FSWs in a city of Guangxi Zhuang Autonomous Region in 2011. Results showed that 71.7% of low-paid FSWs had utilized HTC services in the previous year and 65.7% reported having used a condom during the last sexual intercourse with their clients. Multivariate logistic regression analysis showed that utilizing HTC services was significantly and positively associated with the condom use. It also indicated that low-paid FSWs who were older, married, had higher education, earned less money, had high number of clients, had a history of sexually transmitted diseases, or had little or no HIV knowledge were less likely to use a condom during the last sexual encounter. The study suggests that HTC services need to be scaled up and made more accessible for this vulnerable population.     

HIV Infection, Syphilis, and Behavioral Risks in Brazilian Male Sex Workers

To describe the epidemiology of HIV and syphilis infection and sexual practices among male sex workers, we studied 434 transvestites and 96 hustlers recruited by peers in the metropolitan area of São Paulo, Brazil, from 1992 to 1998. Participants were young adults with low education levels who had recently immigrated to São Paulo and supported themselves primarily through sex work. The prevalence of HIV infection among transvestites and hustlers was 40% and 22% respectively, and the prevalence of current or past syphilis was 43% and 27%, respectively. Infection was associated more with gender performance and duration of sex work than to recent unsafe sexual practices or recent condom use. As opposed to hustlers, whose clients came primarily from São Paulo and were homosexual, transvestites were more likely to have foreign and heterosexual clients. HIV and syphilis among sex workers are urgent public health problems that require continuous prevention programs for male sex workers and their clients.     

2006-2008年北京市暗娼人群梅毒和HIV感染率及梅毒感染率影响因素

目的了解暗娼人群梅毒、艾滋病病毒（HIV）感染率及梅毒感染率的影响因素。方法根据《国家级HIV综合监测点监测方案》,2006—2008年,每年对北京市性服务场所进行分层抽样,对抽中的性服务场所内的暗娼进行HIV抗体检测、梅毒快速血浆反应素试验（RPR）检测和问卷调查。结果2006、2007、2008年,暗娼人群HIV抗体阳性检出率分别为0．12％、0、0．04％,梅毒RPR阳性率分别为1．2％、1．4％和0．8％。影响梅毒阳性率的因素包括：文化程度、婚姻状况、从事性服务的时间、最近一周客人数、与固定性伴发生性行为时安全套使用情况。结论暗娼的性病艾滋病风险不仅来源于商业性行为,还可能来源于非商业性关系。在开展艾滋病行为干预工作时,需要提示暗娼注意与固定性伴性关系中的疾病风险,并鼓励她们坚持使用安全套。文化程度低的暗娼应成为预防干预工作的重点。     

Sexually transmitted infections among brothel-based sex workers in Tel-Aviv area, Israel: high prevalence of pharyngeal gonorrhoea

Sex workers play a major role in spreading sexually transmitted infections (STIs). We studied the prevalence rates and risk factors for STIs among 300 brothel-based sex workers in Tel-Aviv. Throat swabs were cultured for Neisseria gonorrhoeae, urine samples were tested by polymerase chain reaction (PCR) for Chlamydia trachomatis and N. gonorrhoeae, and sera were tested for syphilis, human immunodeficiency virus (HIV) and type 2 herpes simplex virus (HSV) antibodies. N. gonorrhoeae was cultured from throat samples of 9.0% of participants; PCR testing of urine was positive for C. trachomatis in 6.3% and for N. gonorrhoeae in 5.0%. Syphilis serology was positive (Venereal Disease Research Laboratory [VDRL] titres > 1:8) in 1.3% of women, HSV-2-specific immunoglobulin G was detected in 60% and HIV serology was positive in a single case (0.3%). Having STI was significantly associated with age, number of years in Israel, number of clients a week and condom use for vaginal sex. In a multivariate analysis, having STI was significantly associated with number of clients per week and condom use for vaginal sex. The high prevalence of pharyngeal gonorrhoea reflects most probably the expanding demand of clients for oral sex and the insufficient condom use in this form of sex.     

Effectiveness of interventions for the prevention of HIV and other sexually transmitted infections in female sex workers in resource poor setting: a systematic review

Objective To systematically review the evidence for effectiveness of HIV and sexually transmitted infection (STI) prevention interventions in female sex workers in resource poor settings. Method Published and unpublished studies were identified through electronic databases (Cochrane database, Medline, Embase, and Web of Science), hand searching and contacting experts. Randomized‐controlled‐trials and quasi‐experimental studies were included if they were conducted in female sex workers from low and middle income settings; if the exposure was described; if the outcome was externally measurable, it was after the discovery of HIV, and if follow‐up was longer than 6 months. A priori criteria were used to extract data. Meta‐analysis was not performed due to the heterogeneity of studies. Results Twenty‐eight interventions were included. Despite methodological limitations, the evidence suggested that combining sexual risk reduction, condom promotion and improved access to STI treatment reduces HIV and STI acquisition in sex workers receiving the intervention. Strong evidence that regular STI screening or periodic treatment of STIs confers additional protection against HIV was lacking. It appears that structural interventions, policy change or empowerment of sex workers, reduce the prevalence of STIs and HIV. Conclusion Rigorous evaluation of HIV/STI prevention interventions in sex workers is challenging. There is some evidence for the efficacy of multi‐component interventions, and/or structural interventions. The effect of these interventions on the wider population has rarely been evaluated.
