Anal sex and associated HIV-related sexual risk factors among female sex workers in Andhra Pradesh, India

The Moderating Effects of HIV Relevant Factors on the Relationship Between Intimate Partner Violence and Intention to Start HIV Pre-exposure Prophylaxis (PrEP) Among Cisgender Women

Intimate partner violence (IPV) and HIV are serious and related public health problems that detrimentally impact women's health. Because women who experience IPV are more likely to acquire HIV, it is critical to promote HIV prevention strategies, such as HIV pre-exposure prophylaxis (PrEP), that increase autonomy. This study of cisgender women eligible for HIV PrEP took place between 2017 and 2019 in Philadelphia and New York City. This study aimed to examine the relationship between four types of IPV (control, psychological, physical, sexual) and intention to start PrEP among PrEP-eligible cisgender women and assess the extent to which HIV relevant factors moderated the association between IPV experience and intention to start PrEP. In this sample of PrEP-eligible women (n = 214), 68.7% indicated intention to start PrEP in the next 3 months. Ethnicity was strongly associated with intention to start PrEP, with Hispanic women having the highest odds of intending to start PrEP in the next 3 months. Having a controlling partner significantly predicted intention to start PrEP. Women with more than one sex partner and a controlling partner had higher odds of intending to start PrEP as compared with those who had one or no partners and had no IPV control. These findings point to a need for patient-centered interventions that address the need for safety and autonomy among cisgender, PrEP-eligible women.

Lifetime and past-month alcohol use and related factors among female sex workers in Iran

OBJECTIVE

Alcohol use is more common among female sex workers (FSWs). This study assessed the prevalence of lifetime and past-month alcohol use and related factors among FSWs in Iran.

METHODS

We conducted a cross-sectional survey among 1464 women from 8 major cities in Iran. Behavioral data were collected by trained interviewers and conducted face-to-face in a private room. Weighted analysis was used to determine the lifetime and past-month alcohol use prevalence. Univariate and multivariate logistic regression was used to investigate the association between alcohol use and independent variables.

RESULTS

The most alcohol used in lifetime and past-month (weekly, less than once a week, and daily) in FSWs was 52.7% (12.25%, 12.94%, and 1.83%), respectively. In the final model, factors that were independently associated with alcohol use included the 31-40 years (AOR = 2.41, 95% CI: 1.13-5.15), education level of diploma (AOR = 2.43, 95% CI: 1.31-4.51), history of lifetime drug use (AOR = 2.79, 95% CI: 2.01-3.89), history of lifetime group sex (AOR = 2.07, 95% CI: 1.41-3.03), history of intentional abortion (AOR = 1.42, 95% CI: 1.06-1.92), six or more sexual clients in the last month (AOR = 3.25, 95% CI: 1.80-5.87), history of lifetime anal sex (AOR = 2.47, 95% CI: 1.82-3.35), and FSWs the married, temporarily married, and living with partner were positively associated with lifetime alcohol use.

CONCLUSION

Alcohol use is prevalent among FSWs in Iran. Further prevention programs are needed to address and reduce harms associated with alcohol use among this vulnerable population in Iran. Designing intervention programs, it is suggested to consider other variables affecting alcohol use in FSWs.

Prevalence and determinants of heterosexual anal-intercourse among female sex workers in India: Findings from nationwide cross-sectional biological and behavioural survey

BACKGROUND

The vulnerability of female sex workers (FSWs) to HIV infection increases if unprotected heterosexual anal intercourse (HAI) is practiced.

OBJECTIVES

To estimate the prevalence of HAI among FSWs, and associated factors, and prevalence of consistent condom use (CCU) during HAI and associated factors.

METHODS

Analysis of cross-sectional data from nationwide biological and behavioural survey, conducted at 73 randomly selected domains with sample size of 27,000 in India.

RESULTS

A total of 25,932 FSWs were included in the analysis, after excluding 1075 (3.9%) FSWs for which the data were incomplete. The prevalence of HAI was 29.9% (95% CI, 29.3, 30.4); The CCU during HAI in the last one month was 58.9%. Younger age at the start of sex work, use of mobile phone/internet for soliciting client, home as a place of sex work, consumption of alcohol/drug, and physical violence against FSWs were associated with higher odds of HAI. Frequent contact with outreach workers, awareness of sexually transmitted infection, and older age at the start of sex work was associated with CCU.

CONCLUSION

Prevalence of HAI was high among FSW in India. The national program could target those factors that reduce the odds of HAI and/or promote CCU.

Sustaining consistent condom use among female sex workers by addressing their vulnerabilities and strengthening community-led organizations in India

Introduction

Between 2014 and 2017, a program aimed at reducing HIV risk and promoting safe sex through consistent use of condoms sought to work through addressing social and economic vulnerabilities and strengthening community-led organizations (COs) of female sex workers (FSWs). This study examines if the program was effective by studying relationship between strengthening of COs, vulnerability reduction, and sustaining of consistent condom use behavior among FSWs.

Methods

We used a longitudinal study design to assess the change in outcomes. A three-stage sampling design was used to select FSWs for the study. Panel data of 2085 FSWs selected from 38 COs across five states of India was used to examine the change in various outcomes from 2015 (Survey Round 1) to 2017 (Survey Round 2). The CO level program pillar measuring institutional development assessed performance of COs in six domains critical for any organization’s functionality and sustainability: governance, project management, financial management, program monitoring, advocacy and networking, and resource mobilization. Overall, 32 indicators from all these domains were used to compute the CO strength score. A score was computed by taking mean of average dimension scores. The overall score was divided into two groups based on the median cutoff; COs which scored below the median were considered to have low CO strength, while COs which scored above or equal to median were considered to have high CO strength. Multivariable regression modeling techniques were used to examine the effect of program pillars on outcome measures.

Results

Analyses showed a significant improvement in the strength of the COs over time; percentage of COs having high strength improved from 50% in 2015 to 87% in Round 2. The improvement in CO’s strength increased financial security (Adjusted Odds Ratio [AOR]: 2.18, p<0.01), social welfare security (AOR: 1.71, p<0.01), and socio-legal security (AOR: 2.20, p<0.01) among FSWs. Further, improvement in financial security led to significant increase in consistent condom use with client among FSWs (AOR: 1.69, p<0.01) who were members of COs having high strength. Sustained consistent condom use was positively associated with young age (<30 years), ability to negotiate with clients for condom use, membership in self-help groups, high self-efficacy, self-confidence, and client solicitation in streets and brothels.

Conclusions

Improving financial security and strengthening FSW led CO can improve sustained and consistent condom use. In addition, the program should focus on enhancing ability of FSWs to negotiate with clients for condom use, promote membership in self-help groups and target FSWs who are 30 years or older, and soliciting from homes to sustain consistent condom use across all FSWs.

What Proportion of Female Sex Workers Practise anal Intercourse and How Frequently? A Systematic Review and Meta-analysis

HIV is more efficiently acquired during receptive anal intercourse (AI) compared to vaginal intercourse (VI) and may contribute substantially to female sex workers' (FSW) high HIV burden. We aim to determine how common and frequent AI is among FSW globally. We searched PubMed, Embase and PsycINFO for studies reporting the proportion of FSW practising AI (prevalence) and/or the number of AI acts (frequency) worldwide from 01/1980 to 10/2018. We assessed the influence of participant and study characteristics on AI prevalence (e.g. continent, study year and interview method) through sub-group analysis. Of 15,830 identified studies, 131 were included. Nearly all (N = 128) reported AI prevalence and few frequency (N = 13), over various recall periods. Most studies used face-to-face interviews (N = 111). Pooled prevalences varied little by recall period (lifetime: 15.7% 95%CI 12.2-19.3%, N = 30, I2 = 99%; past month: 16.2% 95%CI 10.8-21.6%, N = 18, I2 = 99%). The pooled proportion of FSW reporting < 100% condom use tended to be non-significantly higher during AI compared to during VI (e.g. any unprotected VI: 19.1% 95%CI 1.7-36.4, N = 5 and any unprotected AI: 46.4% 95%CI 9.1-83.6, N = 5 in the past week). Across all study participants, between 2.4 and 15.9% (N = 6) of all intercourse acts (AI and VI) were anal. Neither AI prevalence nor frequency varied substantially by any participant or study characteristics. Although varied, AI among FSW is generally common, inconsistently protected with condoms and practiced sufficiently frequently to contribute substantially to HIV acquisition in this risk group. Interventions to address barriers to condom use are needed.

Prevalence and correlates of anal intercourse among female sex workers in eSwatini

INTRODUCTION

As HIV is very effectively acquired during condomless receptive anal intercourse (AI) with serodiscordant and viremic partners, the practice could contribute to the high prevalence among female sex workers (FSW) in eSwatini (formerly known as Swaziland). We aim to estimate the proportion reporting AI (AI prevalence) among Swazi FSW and to identify the correlates of AI practice in order to better inform HIV prevention interventions among this population.

METHODS

Using respondent-driven sampling (RDS), 325 Swazi FSW were recruited in 2011. We estimated the prevalence of AI and AI with inconsistent condom use in the past month with any partner type, and inconsistent condom use during AI and vaginal intercourse (VI) by partner type. Univariate and multivariable logistic regression models were used to identify behavioural and structural correlates associated with AI and AI with inconsistent condom use.

RESULTS

RDS-adjusted prevalence of AI and AI with inconsistent condom use was high, at 44%[95% confidence interval (95%CI):35-53%]) and 34%[95%CI:26-42%], respectively and did not vary by partner type. HIV prevalence was high in this sample of FSW (70%), but knowledge that AI increases HIV acquisition risk low, with only 10% identifying AI as the riskiest sex act. Those who reported AI were more likely to be better educated (adjusted odds ratio(aOR) = 1.92[95%CI:1.03-3.57]), to have grown up in rural areas (aOR = 1.90[95%CI:1.09-3.32]), have fewer new clients in the past month (aOR = 0.33[95%CI:0.16-0.68]), and for last sex with clients to be condomless (aOR = 2.09[95%CI:1.07-4.08]). Although FSW reporting AI in past month were more likely to have been raped (aOR = 1.95[95%CI:1.05-3.65]) and harassed because of being a sex worker (aOR = 2.09[95%CI:1.16-3.74]), they were also less likely to have ever been blackmailed (aOR = 0.50[95%CI:0.25-0.98]) or been afraid to walk in public places (aOR = 0.46[95%CI:0.25-0.87]). Correlates of AI with inconsistent condom use were similar to those of AI.

CONCLUSIONS

AI is commonly practised and condom use is inconsistent among Swazi FSW. Sex act data are needed to determine how frequently AI is practiced. Interventions to address barriers to condom use are needed, as are biomedical interventions that reduce acquisition risk during AI.

Anal Intercourse Among Female Sex Workers in Côte d'Ivoire: Prevalence, Determinants, and Model-Based Estimates of the Population-Level Impact on HIV Transmission

Current evidence suggests that anal intercourse (AI) during sex work is common in sub-Saharan Africa, but there have been few studies in which the contribution of heterosexual AI to human immunodeficiency virus (HIV) epidemics has been investigated. Using a respondent-driven sampling survey of female sex workers (FSWs; n = 466) in Abidjan, Côte d'Ivoire, in 2014, we estimated AI prevalence and frequency. Poisson regressions were used to identify AI determinants. Approximately 20% of FSWs engaged in AI during a normal week (95% confidence interval: 15, 26). Women who performed AI were generally younger, had been selling sex for longer, were born in Côte d'Ivoire, and reported higher sex-work income, more frequent sex in public places, and violence from clients than women not reporting AI. Condom use was lower, condom breakage/slippage more frequent, and use of water-based lubricants was less frequently reported for AI than for vaginal intercourse. Using a dynamic transmission model, we estimated that 22% (95% credible interval: 11, 37% of new HIV infections could have been averted among FSWs during 2000-2015 if AI had been substituted for vaginal intercourse. Despite representing a small fraction of all sex acts, AI is an underestimated source of HIV transmission. Increasing availability and uptake of condoms, lubricants, and pre-exposure prophylaxis for women engaging in AI could help mitigate HIV risk.

Anal sexual experience and HIV risk awareness among female sex workers in Dire Dawa, eastern Ethiopia

Background

Female sex workers have been disproportionately affected with HIV and anal sexual experience elevate their vulnerability. Anal intercourse has more risk of HIV transmission than vaginal intercourse for receptors that coupled with low condom and proper lubricant use behavior during anal sex. Besides majority of them did not understand HIV transmission risk of anal intercourse. In Ethiopia, studies on anal sexual experience is almost none existent, so the purpose of this study is to explored anal sexual experience and HIV transmission risk awareness among female sex worker in Dire Dawa, Eastern Ethiopia.

Method

Qualitative study with thematic analysis approach was conducted among 18 female sex workers and recruitment of study participants performed until saturation of information. The principal investigator conducted in-depth interviews using local language (Amharic) and it was recorded on audio recorder. Tape recorded data was transcribed and translated to English and entered into open code version 3.4 for coding and theme identification. Data collection conducted simultaneously with data analysis.

Result

Female sex workers practiced anal sex for different themes like financial influence, coercion, intentionally, peer pressure and as a sign of intimacy and love. Coercion, negative attitudes, poor awareness about HIV transmission risks of anal sex and protection capacity of condom and proper lubricants are the identified themes for not using condom and proper lubricants during anal sex by female sex workers. Inaccessibility and unavailability of health services for issues related to anal sex was the core reason for female sex workers’ misperception and risk anal sexual experience.

Conclusion

Female sex workers practiced anal sex without risk reduction approaches and they did not understand exacerbated risk of anal sex to HIV transmission. Stakeholders including ministry of health need to incorporate potential awareness raising tasks and programs about risk of anal sex and methods of risk reduction for female sex workers.

Prevalence of HIV Infection and Risk Factors Among Female Sex Workers in a Southeast Province of Vietnam

Female sex workers (FSWs) are at heightened risk of HIV infection. This research aims to determine the prevalence of HIV and relevant risk factors and related behavior among FSWs in Ba Ria - Vung Tau, a southeast province of Vietnam. 420 FSWs were interviewed using a structured questionnaire and biological samples tested for HIV. 2.6 % were found to be HIV positive. HIV infection was significantly higher in FSWs who had low income (≤AUD 200 per month), have had anal sex, have had sex with injecting drug users, and had a low level of HIV/AIDS-related knowledge. Improved employment opportunities and income are important to reduce the pressure for young women to engage in sex work for income purposes, but in public health terms, existing HIV treatment, prevention and intervention programs needs better targeting and improvements to reduce the risk of HIV infection.

Reducing violence and increasing condom use in the intimate partnerships of female sex workers: study protocol for Samvedana Plus, a cluster randomised controlled trial in Karnataka state, south India

BACKGROUND

Female sex workers (FSWs) are at increased risk of HIV and STIs compared to women in the general population, and frequently experience violence in their working and domestic lives from a variety of perpetrators, which can enhance this risk. While progress has been made in addressing violence by police and clients, little work has been done to understand and prevent violence by intimate partners (IPs) among FSW populations.

METHODS

Samvedana Plus is a multi-level intervention programme that works with FSWs, their IPs, the sex worker community, and the general population, and aims to reduce violence and increase consistent condom use within these 'intimate' relationships. The programme involves shifting norms around the acceptability of beating as a form of discipline, challenging gender roles that give men authority over women, and working with men and women to encourage new relationship models based on gender equity and respect. The programme will aim to cover 800 FSWs and their IPs living in 47 villages in Bagalkot district, northern Karnataka. The study is designed to assess two primary outcomes: the proportion of FSWs who report: (i) physical or sexual partner violence; and (ii) consistent condom use in their intimate relationship, within the past 6 months. The evaluation will employ a cluster-randomised controlled trial design, with 50 % of the village clusters (n = 24) randomly selected to receive the intervention for the first 24 months and the remaining 50 % (n = 23) receiving the intervention thereafter. Statisticians will be blinded to treatment arm allocation. The evaluation will use an adjusted, cluster-level intention to treat analysis, comparing outcomes in intervention and control villages at midline (12 months) and endline (24 months). The evaluation design will involve quantitative and qualitative assessments with (i) all FSWs who report an IP (ii) IPs; and process/ implementation monitoring. Baseline data collection was completed in April 2015, and endline data collection is anticipated in May 2017.

CONCLUSIONS

This is an innovative intervention programme that aims to address violence by IPs as part of HIV prevention programming with FSWs. Reducing violence is expected to reduce vulnerability to HIV acquisition, and help women to work and live without fear of violence.

Pornography, Sexual Enhancement Products, and Sexual Risk of Female Sex Workers and their Clients in Southern India

Despite their large numbers, and important role in the HIV epidemic in India, male clients of female sex workers (FSWs) are a difficult to reach population and little is known about their sexual behaviors. Using data from an integrated behavioral and biological assessment of 684 clients in Bangalore in 2012, we examined factors associated with their reports of having sex with three or more different female sex workers in the last month, and anal sex with sex workers. We included sociodemographic and sexual behavior factors and, for the first time in client studies in India, included data on the use of pornography and sexual enhancement products (SEPs) such as pills, oils, and sprays, in our multivariable analyses of client risk. Seventy-eight percent of clients had seen pornographic material and 8% reported ever having used SEPs. The profiles of men practicing the two risk behaviors examined were quite different. Travel in the past year, drunkenness in the past month, young age at first commercial sex, non-use of condoms at last sex, and finding sex workers in public places (but not use of pornography and SEPs) were independently associated with multiple partnering. Sex with a man or transsexual, being a white collar worker, seeking out FSWs at home, pornography and SEP use, and condom use at last FSW sex, were all independently associated with anal sex with an FSW. More research is needed to better understand the links between pornography and SEPs, and HIV risk behaviors, and HIV prevention programs need to be cognizant of the importance of ensuring that condom use is adequately promoted and supported in the context of anal sex in female sex worker-client interactions.

Degree and correlates of sexual mixing in female sex workers in Karnataka, India

Background The degree of sexual mixing plays an important role in understanding disparities in sexually transmissible infections and HIV across social groups. This study examines the degree of sexual age mixing, and explores its individual and partnership level correlates among female sex workers (FSWs) in Karnataka, India.

METHODS

Data were drawn from special behavioural surveys conducted in 2006-07 among 577 FSWs in two districts of Karnataka: Belgaum and Bangalore. Sexual mixing in age was assessed as the difference in age between FSWs and their sexual partners, and the degree of assortativeness in sexual mixing was assessed using Newman's assortativity coefficient.

RESULTS

A total of 577 FSWs were interviewed; 418 of whom reported two or more partnerships, resulting in 942 partnerships. In about half (52%) of these partnerships, the age difference between the FSW and her sexual partner was 5 years or more. The degree of assortativity in age mixing was 0.098, indicating minimally assortative mixing. The disassortativeness in age mixing was positively associated with young age and no formal education, and negatively with duration in sex work. Partnerships which were of a commercial nature were more likely to be disassortative than noncommercial partnerships.

CONCLUSION

The minimally assortative age mixing indicates sexually transmissible infections can transfer from members of one age group to another. Efforts are required to limit the transmission of infection from one group to other by promoting safer sexual behaviour.

The impact of violence on sex risk and drug use behaviors among women engaged in sex work in Phnom Penh, Cambodia

BACKGROUND

Violence, substance use, and HIV disproportionately impact female entertainment and sex workers (FESW), but causal pathways remain unclear.

METHODS

We examined data from an observational cohort of FESW age 15-29 in Phnom Penh, Cambodia for associations between violence exposure and sexual risk and drug use. Validated measures of physical and sexual violence were assessed at baseline. Self-reported outcomes measured quarterly over the next 12-months included past month sexual partners, consistent condom use by partner type, sex while high, and amphetamine type stimulant (ATS) use. Biomarkers measured quarterly included prostate specific antigen (PSA) and urine toxicology. Generalized estimating equations were fit adjusting for age, education, marital status and sex work venue.

RESULTS

Of 220 women, 48% reported physical or sexual violence in the preceding 12-months. Physical violence was associated with increased number of sex partners (adjusted incidence rate ratio [aIRR] 1.33; 95% CI: 1.04-1.71), greater odds of sex while high (adjusted odds ratio [aOR] 2.42; 95% CI: 1.10-5.33), increased days of ATS use (aIRR 2.74; 95% CI: 1.29-5.84) and increased odds of an ATS+ urine screen (aOR 2.80, 95%CI: 1.38-5.66). Sexual violence predicted decreased odds of consistent condom use with non-paying partners (aOR 0.24; 95% CI: 0.10-0.59) and greater odds of a PSA+ vaginal swab (aOR 1.83; 95% CI: 1.13-2.93).

CONCLUSIONS

Physical and sexual violence are prevalent among Cambodian FESW and associated with subsequent sexual risk and drug use behaviors. Clinical research examining interventions targeting structural and interpersonal factors impacting violence is needed to optimize HIV/AIDS prevention among FESW.

Declines in violence and police arrest among female sex workers in Karnataka state, south India, following a comprehensive HIV prevention programme

Introduction

Female sex workers (FSWs) frequently experience violence, harassment and arrest by the police or their clients, but there is little evidence as to the impact that such factors may have on HIV risk or whether community interventions could mitigate this impact.

Methods

As part of the evaluation of the Avahan programme in Karnataka, serial integrated behavioural and biological assessment (IBBA) surveys (four districts) (2005 to 2011) and anonymous polling booth surveys (PBS) (16 districts) (2007 to 2011) were conducted with random samples of FSWs. Logistic regression analysis was used to assess 1) changes in reported violence and arrests over time and 2) associations between violence by non-partners and police arrest and HIV/STI risk and prevalence. Mediation analysis was used to identify mediating factors.

Results

5,792 FSWs participated in the IBBAs and 15,813 participated in the PBS. Over time, there were significant reductions in the percentages of FSWs reporting being raped in the past year (PBS) (30.0% in 2007, 10.0% in 2011, p<0.001), being arrested in the past year [adjusted odds ratio (AOR) 0.57 (0.35, 0.93), p=0.025] and being beaten in the past six months by a non-partner (clients, police, pimps, strangers, rowdies) [AOR 0.69 (0.49, 0.95), p=0.024)] (IBBA). The proportion drinking alcohol (during the past week) also fell significantly (32.5% in 2005, 24.9% in 2008, 16.8% in 2011; p<0.001). Violence by non-partners (being raped in the past year and/or beaten in the past six months) and being arrested in the past year were both strongly associated with HIV infection [AOR 1.59 (1.18, 2.15), p=0.002; AOR 1.91 (1.17, 3.12), p=0.01, respectively]. They were also associated with drinking alcohol (during the past week) [AOR 1.98 (1.54, 2.53), p<0.001; AOR 2.79 (1.93, 4.04), p<0.001, respectively], reduced condom self-efficacy with clients [AOR 0.36 (0.27, 0.47), p<0.001; AOR 0.62 (0.39, 0.98), p=0.039, respectively], symptomatic STI (during the past year) [AOR 2.62 (2.07, 3.30), p<0.001; AOR 2.17 (1.51, 3.13), p<0.001, respectively], gonorrhoea infection [AOR 2.79 (1.51, 5.15), p=0.001; AOR 2.69 (0.96, 7.56), p=0.060, respectively] and syphilis infection [AOR 1.86 (1.04, 3.31), p=0.036; AOR 3.35 (1.78, 6.28), p<0.001, respectively], but not with exposure to peer education, community mobilization or HIV testing uptake. Mediation analysis suggests that alcohol use and STIs may partially mediate the association between violence or arrests and HIV prevalence.

Discussion

Violence by non-partners and arrest are both strongly associated with HIV infection among FSWs. Large-scale, comprehensive HIV prevention programming can reduce violence, arrests and HIV/STI infection among FSWs.

Mediation analysis suggests that alcohol use and STIs may partially mediate the association between violence or arrests and HIV prevalence.

DISCUSSION

Violence by non-partners and arrest are both strongly associated with HIV infection among FSWs. Large-scale, comprehensive HIV prevention programming can reduce violence, arrests and HIV/STI infection among FSWs.

Inconsistent condom use by male clients during anal intercourse with occasional and regular female sex workers (FSWs): survey findings from southern states of India

OBJECTIVES

Self-reported anal intercourse by female sex workers (FSWs) documented in recent studies from India range between 11.9% and 22%. However, comparable data on anal intercourse and condom use from male clients of FSWs is lacking. Using data from a bio-behavioural survey (2009-2010), we examined prevalence of anal intercourse, male clients' self-reported inconsistent condom use during anal intercourse with FSWs, and correlates of this behaviour in India's high HIV prevalence southern states (Andhra Pradesh, Maharashtra and Tamil Nadu combined).

METHODS

Using two-stage time location cluster sampling, we recruited 4803 clients of FSWs, ages 18-60 years, who had purchased sex from an FSW in the past month. After obtaining informed consent, respondents were interviewed and tested for HIV and sexually transmitted infections (syphilis, gonorrhoea and chlamydia). Logistic regression analysis was used to identify the factors associated with inconsistent condom use during anal intercourse (in the past 6 months) with FSWs.

RESULTS

Overall, 12.3% clients reported anal intercourse in the past 6 months, of whom 48.4% used condoms inconsistently. Clients of FSWs who were ages 26 years or older (AOR 2.68, p=0.032); employed as manual labourers (AOR 2.43, p=0.013); consumed alcohol (AOR 2.63, p=0.001); reported five or more sex acts with FSWs in the past month (AOR 2.53, p=0.031); and perceived themselves to be at higher risk for HIV (AOR 4.82, p=0.001) were more likely to inconsistently use condoms during anal intercourse.

CONCLUSIONS

The results suggest that sex workers and their clients commonly practice anal intercourse, but a relatively high proportion of clients do not consistently use condoms, leading to a greater risk of acquiring HIV and its further transmission to other male and female sexual partners. Given the multidirectional risk, safer sex communication on heterosexual anal intercourse must be incorporated into HIV prevention programmes.

Heterosexual anal sex among female sex workers in high HIV prevalence states of India: need for comprehensive intervention

INTRODUCTION

Role of vaginal sex in heterosexual transmission of HIV has been investigated but that of heterosexual anal sex (HAS) is not fully understood. This paper examines practice of HAS among Female Sex Workers (FSWs) and its correlates in India where the HIV epidemic is being primarily driven by core groups like FSWs.

METHODS

Data for this paper are drawn from Round I survey of 9667 FSWs in the Integrated Biological and Behavioral Assessment (IBBA) from 23 districts of 4 high HIV prevalent states of India. Bivariate and multivariate analysis identified factors associated with HAS.

RESULTS

Ever having anal sex was reported by 11.9% FSWs (95% CI: 11.3%-12.6%). Typology (AOR 2.20, 95% CI 1.64-2.95) and literacy (AOR 1.28, 95% CI 1.10-1.49) were positively associated with practice of HAS. Longer duration in sex trade (AOR 1.69, 95% CI 1.44-1.99), entertaining larger number of clients the previous week (AOR 1.78, 95% CI 1.47-2.15), alcohol consumption (AOR 1.21, 95% CI 1.03-1.42) and inability to negotiate condom use (AOR 1.53, 95% CI 1.28-1.83) were also correlated with HAS. Self-risk perception for HIV (AOR 1.46, 95% CI 1.25-1.71) did not impede HAS. Although symptoms of sexually transmitted infections (STIs) in the last 12 months were associated with anal sex (AOR 1.39, 95% CI 1.13-1.72) there was no significant association between laboratory confirmed HIV and other STIs with HAS.

CONCLUSION

Practice of HAS by FSWs might significantly contribute to HIV transmission in India. This study also shows that despite self-risk perception for HIV, even literate FSWs with longer duration in sex work report HAS. General messages on condom use may not influence safe HAS. FSWs need to be targeted with specific messages on HIV transmission during anal sex. Women controlled prevention methods, such as rectal microbicides and vaginal microbicides are needed.

Violence against women in sex work and HIV risk implications differ qualitatively by perpetrator

Background

Physical and sexual violence heighten STI/HIV risk for women in sex work. Against this backdrop, we describe the nature of abuse against women in sex work, and its STI/HIV implications, across perpetrators.

Methods

Adult women involved in sex work (n = 35) in Baltimore, MD participated in an in-depth interview and brief survey.

Results

Physical and sexual violence were prevalent, with 43% reporting past-month abuse. Clients were the primary perpetrators; their violence was severe, compromised women’s condom and sexual negotiation, and included forced and coerced anal intercourse. Sex work was a factor in intimate partner violence. Police abuse was largely an exploitation of power imbalances for coerced sex.

Conclusions

Findings affirm the need to address physical and sexual violence, particularly that perpetrated by clients, as a social determinant of health for women in sex work, as well as a threat to safety and wellbeing, and a contextual barrier to HIV risk reduction.

Factors associated with risky sexual practices among female sex workers in Karnataka, India

Introduction

The objectives of this study are to develop a summary measure of risky sexual practice and examine the factors associated with this among female sex workers (FSWs) in Karnataka, India.

Materials and Methods

Data were drawn from special behavioral surveys (SBS) conducted in 2007 among 577 FSWs in two districts of Karnataka, India: Belgaum and Bangalore. FSWs were recruited using the two-stage probability sampling design. FSWs' sexual practice was considered risky if they reported inconsistent condom use with any sexual partner and reported experience of one of the following vulnerabilities to HIV risk: anal sex, alcohol consumption prior to sex and concurrent sexual relationships.

Results

About 51% of FSWs had engaged in risky sexual practice. The odds of engaging in risky sex were higher among FSWs who were older (35+ years) than younger (18–25 years) (58% vs. 45%, Adjusted Odds Ratio (AOR): 2.0, 95% confidence interval (CI): 1.2–3.4), who were currently married than never married (61% vs. 51%, AOR: 4.8, 95% CI: 2.5–9.3), who were in sex work for 10+ years than those who were in sex work for less than five years (66% vs. 39%, AOR: 2.6, 95% CI: 1.6–4.2), and who had sex with 3+ clients/day than those who had sex with fewer clients (67% vs. 38%, AOR: 3.7, 95% CI:2.5–5.5).

Conclusion

FSWs who are older, currently married, practicing sex work for longer duration and with higher clientele were more likely to engage in risky sexual practices. HIV prevention programs should develop strategies to reach these most-at risk group of FSWs to optimize the effectiveness of such programs.
