Abstract
Female entertainment and sex workers (FESW) have high rates of alcohol and amphetamine-type stimulant (ATS) use, increasing risk for HIV/sexually transmitted infections (STI), and other negative outcomes. A prospective cohort of 1,198 FESW in a HIV/ATS use prevention intervention in Cambodia was assessed for alcohol and stimulant use disorders (AUD and SUD) using the Alcohol and Substance Use Involvement (ASSIST) scale. STI history was measured by self-report at baseline and at quarterly follow-up visits. Participants were asked if they had been diagnosed with an STI by a medical provider in the past 3 months. Marginal structural models were used to estimate joint effects of AUD and SUD on recent STI. At baseline, one-in-four screened AUD positive and 7% screened positive for SUD. At 18-months, 26% reported ≥1 recent STI. Accounting for time-varying and other known confounders, the adjusted odds ratio (AOR) for recent STI associated with AUD alone and SUD alone were 2.8 (95% CI:1.5-5.1) and 3.5 (95% CI:1.1-11.3), respectively. The AOR for joint effects of AUD and SUD was 5.7 (95% CI:2.2-15.2). AUD and SUD are independently and jointly associated with greater odds of STI among Cambodian FESW. Further research is critical for understanding how AUD and SUD potentiate biological and behavioural pathways that influence STI acquisition and to inform HIV risk-reduction interventions in FESW.

Abstract
Targeted HIV interventions for female sex workers (FSW) combine biomedical technologies, behavioural change and community mobilization with the aim of empowering FSW and improving prevention and treatment. Understanding how to deliver combined interventions most effectively in sub-Saharan Africa is critical to the HIV response. The Sisters' Antiretroviral Programme for Prevention of HIV: an Integrated Response (SAPPH-Ire) randomized controlled trial in Zimbabwe tested an intervention to improve FSW engagement with HIV services. After 2 years, results of the trial showed no significant difference between study arms in proportion of FSW with HIV viral load ≥1000 copies/ml as steep declines occurred in both. We present the results of a process evaluation aiming to track the intervention's implementation, assess its feasibility and accessibility, and situate trial results within the national HIV policy context. We conducted a mixed methods study using data from routine programme statistics, qualitative interviews with participants and respondent driven surveys. The intervention proved feasible to deliver and was acceptable to FSW and providers. Intervention clinics saw more new FSW (4082 vs 2754), performed over twice as many HIV tests (2606 vs 1151) and nearly double the number of women were diagnosed with HIV (1042 vs 546). Community mobilization meetings in intervention sites also attracted higher numbers. We identified some gaps in programme fidelity: offering pre-exposure prophylaxis took time to engage FSW, viral load monitoring was not performed, and ratio of peer educators to FSW was lower than intended. During the trial, reaching FSW with HIV testing and treatment became a national priority, leading to increasing attendance at both intervention and control clinics. Throughout Zimbabwe, antiretroviral therapy coverage improved and HIV-stigma declined. Zimbabwe's changing HIV policy context appeared to contribute to positive improvements across the HIV care continuum for all FSW over the course of the trial. More intense community-based interventions for FSW may be needed to make further gains.

Abstract
The objective of this paper was to identify factors related to the use of HIV testing among cross border migrants in Thailand. Two measures of vulnerability (social integration and legal/economic status) as well as HIV knowledge, risk behaviour, and demographic factors were tested for association with HIV testing. Data were drawn from a survey of 2600 sexually active migrants age 15-59 in multiple provinces of Thailand. The measures of social integration (AOR = 1.14(95 % CI 1.09, 1.20) female; AOR = 1.12 (95 %CI 1.05, 1.19) male) and legal-income status (AOR = 1.12 (95 % CI 1.07, 1.18) female; AOR = 1.31 (95 %CI 1.20, 1.42) male) were positively related to the odds of reporting an HIV test for both male and female migrants. Exposure to AIDS programming including attending an AIDS meeting and possessing AIDS knowledge was also related to an increase in HIV testing. In addition, reproductive health factors including sexual risk behavior and childbirth increased the rate of HIV testing.

Abstract
OBJECTIVE To assess contraceptive uptake and method choice among women living with HIV (WLHIV) attending an HIV care clinic serving most-at-risk women in Phnom Penh, Cambodia, before and after the implementation of family planning (FP) services. METHODS Semistructured questionnaires were administered to clients before (July, 2011) and after (July, 2012) FP service implementation with provision of contraceptive methods (pills, injectables, implants, and intrauterine device [IUD]). RESULTS Among 250 and 249 clients interviewed before and after implementation respectively, 24.5% of women reported selling sex for money during the last 6 months before and 35.3% after implementation. Awareness about contraceptive methods significantly increased among clients postimplementation. Among sexually active women, male condom remained the contraceptive method of choice with an overall condom use during the last 6 months at 91% postimplementation vs. 95.6% preimplementation (P = 0.11). Although the use of noncondom FP methods increased but not significantly (16.4% after vs. 12.6% before implementation, P = 0.8), the use of dual method (condom plus another method) remained low and did not significantly increase after implementation (14.8% after vs. 11.0% before, P = 0.28). CONCLUSIONS Our results show that FP practices of WLHIV attending an HIV care clinic for most-at-risk populations did not significantly change after integration on-site provision of a wide range of FP methods. Innovative strategies and further research are needed to better understand how to promote the use of noncondom FP methods and prevent unwanted pregnancies and abortions among most-at-risk women and WLHIV.

Abstract
BACKGROUND Accurate measurement of unprotected sex is essential in HIV prevention research. Since 2001, the 100% Condom Use Program targeting female sex workers (FSWs) has been a central element of the Cambodian National HIV/AIDS Strategy. We sought to assess the validity of self-reported condom use using the rapid prostate-specific antigen (PSA) test among Cambodian FSWs. METHODS From 2009 to 2010, we enrolled 183 FSWs in Phnom Penh in a prospective study of HIV risk behavior. Prostate-specific antigen test results from the OneStep ABAcard were compared with self-reported condom use in the past 48 hours at quarterly follow-up visits. RESULTS Among women positive for seminal fluid at the first follow-up visit, 42% reported only protected sex or no sex in the detection period. Discordant results were more likely among brothel and street-based FSW versus entertainment (56% vs. 17%), recent (last 3 months) amphetamine-type stimulant (ATS) users (53% vs. 20%), and those with 5 or more partners in the past month (58% vs. 13%). In multivariable regression models, positive PSA results were associated with recent ATS use (adjusted risk ratio [ARR], 1.5; 95% confidence interval [CI], 1.1-2.2), having a nonpaying last sex partner (ARR, 1.7; CI, 1.2-2.5), and sex work venue (ARR, 3.0; CI, 1.4-6.5). Correspondingly, women with a nonpaying last sex partner were more likely to report unprotected sex (ARR, 1.5; CI, 1.1-2.2), but no associations were found with sex work venue or ATS use. CONCLUSIONS Results confirm the questionable validity of self-reported condom use among FSW. The PSA biomarker assay is an important monitoring tool in HIV/sexually transmitted infection research including prevention trials.

Abstract
OBJECTIVES HIV prevalence among Cambodian female sex workers (FSW) is among the highest in Southeast Asia. We describe HIV prevalence and associated risk exposures in FSW sampled serially in Phnom Penh, Cambodia (Young Women's Health Study (YWHS)), before and after the implementation of a new law designed to combat human trafficking and sexual exploitation. DESIGN Cross-sectional analysis of baseline data from two prospective cohorts. SETTING Community-based study in Phnom Penh, Cambodia. PARTICIPANTS Women aged 15-29 years, reporting ≥2 sexual partners in the last month and/or engaged in transactional sex in the last 3 months, were enrolled in the studies in 2007 (N=161; YWHS-1), and 2009 (N=220; YWHS-2) following information sessions where 285 and 345 women attended. PRIMARY OUTCOMES HIV prevalence, sexual risk behaviour, amphetamine-type stimulant (ATS) and alcohol use, and work-related factors were compared in the two groups, enrolled before and after implementation of the new law. RESULTS Participants in the two cohorts were similar in age (median 25 years), but YWHS-2 women reported fewer sex partners, more alcohol use and less ATS use. A higher proportion of YWHS-2 compared with YWHS-1 women worked in entertainment-based venues (68% vs 31%, respectively). HIV prevalence was significantly lower in the more recently sampled women: 9.2% (95% CI 4.5% to 13.8%) vs 23% (95% CI 16.5% to 29.7%). CONCLUSIONS Sex work context and risk have shifted among young FSW in Phnom Penh, following implementation of anti-prostitution and anti-trafficking laws. While both cohorts were recruited using the same eligibility criteria, more recently sampled women had lower prevalence of sexual risk and HIV infection. Women engaging more directly in transactional sex have become harder to sample and access. Future prevention research and programmes need to consider how new policies and demographic changes in FSW impact HIV transmission.

Abstract
Cambodia's 100% Condom Use Programme is credited with an increase in consistent condom use in commercial sexual interactions and a decrease in HIV prevalence among female sex workers (FSWs). There has been little improvement in condom use between FSWs and non-commercial partners, prompting calls for more innovative approaches to increasing condom use in these relationships. To understand why condoms are used or not used in sexual interactions involving FSWs, we examined condom negotiation across different types of relationships. We conducted 33 in-depth interviews with young (15 to 29 years) women engaged in sex work in Phnom Penh. There was an important interplay between the meanings of condom use and the meanings of women's relationships. Commercial relationships were characterised as inherently risky and necessitated condom use. Despite a similar lack of sexual fidelity, sweetheart relationships were rarely construed as risky and typically did not involve condom use. Husbands and wives constructed their sexual interactions with each other differently, making agreement on condom use difficult. The lack of improvement in condom use in FSWs' non-commercial sexual relationships needs to be understood in relation to both sex work and the broader Cambodian sexual culture within which these relationships are embedded.

Abstract
We examined condom-use negotiation strategies and condom use among 81 female sex workers (FSWs) in Phnom Penh, Cambodia. Percentages of FSWs who did not negotiate condom use or could not describe a negotiation strategy with native clients, foreign clients, and non-paying partners were 15.0, 29.0 and 67.6 %, respectively. The most common negotiation strategy used was "provision of risk information" for native clients (43.8 %) and non-paying partners (26.5 %), and "direct request" for foreign clients (39.5 %). About half could not describe more than one negotiation strategy. Consistent condom use was high with native clients (98.8 %), yet comparatively lower with foreign clients (86.9 %) and non-paying partners (26.5 %). FSWs who did not negotiate or did not know how to negotiate condom use were less likely to report condom use with non-paying regular partners. Future interventions should enhance condom negotiation strategies between FSWs and all partner types.

Abstract
This study uses multilevel analysis to examine individual, organizational and community levels of influence on condom use among female commercial sex workers (FSW) in the Philippines. A randomized controlled study involving 1,382 female commercial sex workers assigned to three intervention groups consisting of peer education, managerial training, combined peer and managerial intervention and a usual care control group was conducted. The results of the multilevel analysis show that FSWs who work in establishments with condom use rules tend to have a higher level of condom use (β = .70, P < 0.01). Among the different intervention groups, the combined peer and managerial intervention had the largest effect on condom use (β = 1.30, P < 0.01) compared with the usual care group. Using a three-level hierarchical model, we found that 62% of the variation lies within individuals, whereas 24% and 14% of the variation lies between establishments, and communities, respectively. Standard errors were underestimated when clustering of the FSWs in the different establishments and communities were not taken into consideration. The results demonstrate the importance of using multilevel analysis for community-based HIV/AIDS intervention programs to examine individual, establishment and community effects.

Abstract
BACKGROUND Various interventions have been adopted to reduce HIV transmission among sex workers and their clients but the effectiveness of these strategies has yet to be investigated using meta-analytic techniques. OBJECTIVES To evaluate the effectiveness of behavioral interventions to reduce the transmission of HIV infection among sex workers and their clients in low- and middle-income countries. SEARCH METHODS The Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane HIV/AIDS group specialized register, the Cochrane Database of Systematic Reviews, MEDLINE, PsycINFO, Sociological Abstracts, CINAHL, Dissertation Abstract International (DAI), EMBASE, LILACS, BIOSIS, SciSearch, INDMED, Proquest, and various South Asian abstracting databases were included in the database list. The publication sites of the World Health Organization, the US Centers for Disease Control and Prevention, and other international research and non-governmental organizations also appeared in the database list. SELECTION CRITERIA Randomized controlled trials (RCTs) and quasi-RCTs examining the effects on HIV transmission risk of different behavioral interventions or comparing behavioral interventions with no intervention, where described any one of the outcome measures, such as HIV incidence and prevalence, STI incidence and prevalence, change in self-reported of condom use, and other HIV-related outcome. DATA COLLECTION AND ANALYSIS Two authors independently assessed trials, extracted data and assessed the risk bias. Heterogeneity amongst trials was also tested. MAIN RESULTS A total of 13 trials with 8,698 participants were included. Primary outcomes (HIV and STI prevalence and incidence) were reported in seven trials. Of these, HIV incidence was reported in only three trials. After a 6-month follow-up assessment, there was no evidence that social cognitive behavioral intervention was effective in reducing HIV incidence (RR 0.12, 95% CI 0.01 to 2.22). However, there was a reduction in HIV incidence at 3-month follow-up assessment of promotion of female and male condom (RR 0.07, 95% CI 0.00 to 1.38). Social cognitive interventions and promotion of female and male condom use were significantly reduced STIs incidence (RR 0.57, 95% CI 0.34 to 0.96) and (RR 0.63, 95% CI 0.45 to 0.88), respectively. Secondary outcomes were identified in 13 trials. Meta-analyses showed evidence that interventions to promote the use of female and male condoms do reduce non-condom use (RR 0.83, 95% CI 0.65 to 1.05) compared to promotion of male condoms alone, and that social cognitive interventions reduced drug use among sex workers (RR 0.65, 95% CI 0.36 to 1.16) compared to standard care. AUTHORS' CONCLUSIONS Available evidence nevertheless suggests that compared with standard care or no intervention, behavioral interventions are effective in reducing HIV and the incidence of STIs amongst female sex workers (FSWs). Given the benefits of social cognitive theory and the promotion of condom use in reducing HIV/STI and the public health need to control transmission amongst FSWs, there is a clear finding in favour of behavioral interventions. However, it should be recognized that there is a lack of information about most other outcomes and target populations, and that all of the trials were conducted in low- and middle-income countries.

Abstract
OBJECTIVES To estimate prevalence and incidence of HIV and sexually transmitted infections (STI) and associated risk factors among young women working as sex workers (SWs) in Phnom Penh, Cambodia. METHODS A prospective study of young (<29 years) women working as SWs in brothels, entertainment establishments, and freelance. Sociodemographics, sexual risk, and use of amphetamine-type stimulants (ATS) ("yama" and "crystal") were assessed by self-report. HIV and STI (Chlamydia trachomatis and Neisseria gonorrhoeae) testing were conducted on blood and urine specimens, respectively. RESULTS Baseline prevalences of HIV, C. trachomatis, and N. gonorrhoeae were 23%, 11.5%, and 7.8%, respectively. HIV incidence was 3.6 per 100 person-years (95% confidence interval [CI], 1.2%-11.1%); STI incidence was 21.2 per 100 person-years (95% CI, 12.6%-35.8%). At baseline, 26.5% reported recent ATS use. HIV infection was associated with freelance SW (adjusted odds ratio, 5.85; 95% CI, 1.59-21.58) and younger age of first sex (≤15 years; adjusted odds ratio, 3.06; 95% CI, 1.01-8.46). Incident STI was associated with duration (per year) of SW (adjusted hazard ratio, 1.1; 95% CI, 1.1-1.2) and recent yama use (adjusted hazard ratio, 3.9; 95% CI, 1.5-10.3). CONCLUSIONS HIV and STI infection rates were high among SWs working in various settings; freelancers had highest risk. ATS use was associated with incident STI. Venue of sex work and drug prevention should be considered in prevention programs.

Abstract
To determine the prevalence of HIV and correlates of HIV infection among female sex workers (FSWs) in Soc Trang province, Vietnam, a survey of 406 FSWs in Soc Trang province was conducted between May and August, 2003. The participants were interviewed, using a standardized interview, to obtain information about socio-demographic and behavioral characteristics, and gynecologic and sexually transmitted infection (STI) history. The prevalence of HIV was 3.3%. An increased risk for HIV was associated with ever using illicit drugs, direct sex work, early sexual debut, age of FSWs, and infection with candidiasis and trichomoniasis. Reduced likelihood of HIV was only associated with withdrawal as a contraceptive method. A strong association of HIV with drug use and candidiasis and trichomoniasis infection among FSWs was found. Needle/syringe exchange, STI treatment, and methadone programs targeting FSWs should be implemented, and should include 100% condom use promotion.

Sopheab H, Morineau G, Neal JJ, Saphonn V, Fylkesnes K. Sustained high prevalence of sexually transmitted infections among female sex workers in Cambodia: high turnover seriously challenges the 100% Condom Use Programme. BMC Infect Dis 2008; 8:167. [PMID: 19077261 PMCID: PMC2640393 DOI: 10.1186/1471-2334-8-167] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2008] [Accepted: 12/12/2008] [Indexed: 11/10/2022] Open
Abstract
Background Cambodia's 100% Condom-Use Programme (CUP), implemented nationally in 2001, requires brothel-based female sex workers (FSWs) to use condoms with all clients. In 2005, we conducted a sexually transmitted infection (STI) survey among FSWs. This paper presents the STI prevalence and related risk factors, and discusses prevalence trends in the context of the 100% CUP in Cambodia. Methods From March-May, 1079 FSWs from eight provinces consented to participate, provided specimens for syphilis, chlamydia, and gonorrhoea testing, and were interviewed. Univariate and multivariate logistic regression analysis was used to determine factors associated with STIs. STI prevalence was compared with data from the 1996 and 2001 STI surveys. Results Most FSWs were young (55% aged 15–24) and new to sex work (60% had worked 12 ≤ months). Consistent condom use with clients was reported by 80% of FSWs, but only 38% of FSWs always used condoms with sweethearts or casual partners. Being new to sex work was the only factor significantly associated with "any STI" (OR = 2.1). Prevalence of syphiliwas 2.3%; chlamydia, 14.4%; gonorrhoea, 13.0%; and any STI, 24.4%. Prevalence of each STI in 2005 was significantly lower than in 1996, but essentially the same as prevalence observed in 2001. Conclusion New FSWs were found to have substantially higher prevalence than those with longer experience. The percent of FSWs who used condoms consistently was high with clients but remained low with non-paying sex partners. Because of the high turnover of FSWs, the prevention needs of new FSWs should be ascertained and addressed. Despite 100% CUP implementation, the prevalence of STIs among FSWs was the same in 2005 as it was in 2001. Limited coverage and weak implementation capacity of the programme along with questionable quality of the STI services are likely to have contributed to the sustained high prevalence. The programme should be carefully reviewed in terms of intensity, quality and coverage.

Abstract
OBJECTIVES To document the pilot experience of provision of safe abortion/post-abortion services implemented in 2002 at the Mother Child Health clinic in Sihanoukville, Cambodia, and to profile clients and assess their uptake of post-abortion contraception. METHODS The initial package of safe abortion/post-abortion clinics (SAPAC) services included counselling on family planning and prevention of sexually transmitted infections, pain management, Manual Vacuum Aspiration procedure and standard universal precautions at an affordable price (US$12.5). SAPAC services became operational in August 2002. The data of medical records from 1 August 2002 to 31 December 2005 (2224 clients) were analysed. RESULTS The mean number of clients per month attending SAPAC services ranged from 26 in 2002 to 64 in 2005. Fifty-three per cent were housewives, 24% worked in sales or services, 8% in factories, 11% in bars or karaoke lounges and 3% were brothel-based sex workers. Ninety-three per cent of clients came for induced abortion and 7% sought post-abortion care. Pain management was used in 99% of cases. The overall rate of complications during intervention was 2.1% and dropped from 9.4% in 2002 to 1.3% in 2005. After SAPAC implementation, fewer women in Sihanoukville sought abortion services without any quality control and a safer technique was used. On average, 40% of patients took up contraception after the abortion. CONCLUSIONS Integrating comprehensive abortion-care services at a peripheral government health facility is feasible. There is a demand for such services provided at an affordable price in Sihanoukville, Cambodia.

Abstract
Background Efforts at HIV prevention that focus on high risk places might be more effective and less stigmatizing than those targeting high risk groups. The objective of the present study was to assess risk behaviour patterns, signs of current preventive interventions and apparent gaps in places where the risk of HIV transmission is high and in communities with high HIV prevalence. Methods The PLACE method was used to collect data. Inhabitants of selected communities in Lusaka and Livingstone were interviewed about where people met new sexual partners. Signs of HIV preventive activities in these places were recorded. At selected venues, people were interviewed about their sexual behaviour. Peer educators and staff of NGOs were also interviewed. Results The places identified were mostly bars, restaurants or sherbeens, and fewer than 20% reported any HIV preventive activity such as meetings, pamphlets or posters. In 43% of places in Livingstone and 26% in Lusaka, condoms were never available. There were few active peer educators. Among the 432 persons in Lusaka and 676 in Livingstone who were invited for interview about sexual behaviour, consistent condom use was relatively high in Lusaka (77%) but low in Livingstone (44% of men and 34% of women). Having no condom available was the most common reason for not using one. Condom use in Livingstone was higher among individuals socializing in places where condoms always were available. Conclusion In the places studied we found a high prevalence of behaviours with a high potential for HIV transmission but few signs of HIV preventive interventions. Covering the gaps in prevention in these high exposure places should be given the highest priority.

Abstract
OBJECTIVES To assess HIV prevalence and risk factors for HIV infection, to investigate condom use among registered female commercial sex workers (CSWs) in Senegal, West Africa, and to examine the association between previous HIV testing, knowledge of HIV serostatus and condom use with both regular sex partners and clients within this population. METHODS A cross-sectional study was conducted at three sexually transmitted disease clinics among 1052 Senegalese registered CSWs between 2000 and 2004. Inperson interviews soliciting information concerning demographic characteristics, medical history, sexual behaviour with clients and regular partners, and previous HIV testing history were performed. Blood samples were collected for determination of HIV-1 and/or HIV-2 serostatus. Multivariable, Poisson and log-binomial models were used to calculate prevalence ratios. RESULTS The overall HIV prevalence was 19.8%. Over 95% of CSWs reported always using a condom with clients, but only 18% reported always using a condom with their regular partners. A history of previous HIV testing was not associated with condom use with clients (adjusted prevalence ratio (APR) = 0.98, 95% confidence intervals, CI: 0.90 to 1.06). However, prior HIV testing was associated with decreased condom use with their regular partners (APR = 0.44, 95% CI: 0.28 to 0.69), especially in women who tested HIV negative (APR = 0.17, 95% CI: 0.08 to 0.36). CONCLUSIONS CSWs in Senegal have a high HIV prevalence; therefore preventing HIV transmission from this population to the general population is important. Condom use with regular partners is low among registered CSWs in Senegal, and a prior HIV negative test is associated with even less condom use with regular partners. Intervention efforts to increase condom use with regular sexual partners are needed.
