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

HIGHLIGHTS
  • Almost half the women engaged in sex work reported violence in the past 12 months.
  • Prior physical violence exposure associated with subsequent sexual risk taking.
  • Physical violence was associated with amphetamine type stimulant (ATS) use.
  • Sexual violence was associated lower levels of condom use with non-paying partners.

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.

Culturally Embedded Risk Factors for Cambodian Husband-Wife HIV Transmission: From Women's Point of View

PURPOSE:
The purpose of this study was to use interview data to examine the validity of a recently published theoretical model of HIV transmission between husband and virginal wives in rural Cambodia.

DESIGN:
This study used a qualitative description method with a sample of women diagnosed with HIV/AIDS in Phnom Penh, Cambodia.

METHODS:
Data were collected through in-depth interviews conducted with 15 women who self-identified as having contracted HIV from their HIV-positive husbands. Interviews were conducted in Khmer, translated and back-translated for accuracy, and then coded using deductive content analysis. Trustworthiness of study results was protected through peer debriefing, coding to consensus, and maintaining an audit trail.

FINDINGS:
Each conceptual domain of the prior published theoretical model of HIV transmission was validated and further elaborated by current study data: wives' acceptance of their husbands' involvement with commercial sex workers, the common practice of unprotected sex between HIV-infected spouses and uninfected wives, and wives' beliefs about the value of the ideal Khmer woman. In addition, the current study findings identified a new domain that substantially distinguished between the beliefs and attitudes held about marriage and sex by wives and spouses.

CONCLUSIONS:
Women were not passive recipients of HIV transmission; they reciprocated with behaviors that were consistent with being a good Khmer woman in rural Cambodia, all of which increased their vulnerability to HIV transmission from their HIV-infected spouses. Future interventions or programs should consider all these factors and not overly rely on simplistic educational messages about wearing barriers for HIV transmission during sex.

CLINICAL RELEVANCE:
The refined theoretical model of HIV transmission from this qualitative research can be used to formulate culturally sensitive and embedded programs for curbing intramarital HIV transmission in Cambodia among the rural poor.

Intravaginal Practices in Female Sex Workers in Cambodia: A Qualitative Study

Intravaginal practices (IVPs) are associated with several adverse health outcomes, including HIV infection. However, few studies have examined this topic in Asian cultures, particularly in female sex workers (FSWs). 

This theory-based qualitative study aimed to describe the IVPs and to identify salient determinants of these practices in FSWs in Phnom Penh, Cambodia. We conducted in-depth interviews using open-ended questions with 30 FSWs in July-August 2014. We analyzed data using thematic content analysis, with thematic codes based on the constructs of the theory of planned behavior. 

The results showed that the most common IVP was a combination of intravaginal washing and wiping, to which we refer as intravaginal cleansing. There was a clear and close connection between IVP and sex work. Perceived benefits of intravaginal cleansing were numerous, while the perceived risks were few. As a result, the attitude toward intravaginal cleansing was favorable. 

A common misperception of benefit was that intravaginal cleansing could prevent sexually transmitted infections. Local physicians considerably influenced the subjective norm related to IVP. Intention to quit IVPs was suboptimal. 

In conclusion, the psychological factors associated with IVPs in FSWs were somewhat different from those in the general population of Cambodian women and women in other countries. Behavioral beliefs, attitude, and subjective norms appeared salient and important factors in IVPs. Interventions aimed at reducing IVPs should target these constructs as well as the sex-work-associated economic motives. Local physicians may be an agent to change IVP and an effective channel to deliver interventions.

Advanced HIV Disease at Enrolment in HIV Care: Trends and Associated Factors over a Ten Year Period in Cambodia

Background
Early HIV diagnosis and enrolment in care is needed to achieve early antiretroviral treatment (ART) initiation. Studies on HIV disease stage at enrolment in care from Asian countries are limited. We evaluated trends in and factors associated with late HIV disease presentation over a ten-year period in the largest ART center in Cambodia.

Methods
We conducted a retrospective analysis of program data including all ARV-naïve adults (> 18 years old) enrolling into HIV care from March 2003-December 2013 in a non-governmental hospital in Phnom Penh, Cambodia. We calculated the proportion presenting with advanced stage HIV disease (WHO clinical stage IV or CD4 cell count <100 cells/μL) and the probability of ART initiation by six months after enrolment. Factors associated with late presentation were determined using multivariate logistic regression.

Results
From 2003–2013, a total of 5642 HIV-infected patients enrolled in HIV care. The proportion of late presenters decreased from 67% in 2003 to 44% in 2009 and 41% in 2013; a temporary increase to 52% occurred in 2011 coinciding with logistical/budgetary constraints at the national program level. Median CD4 counts increased from 32 cells/μL (IQR 11–127) in 2003 to 239 cells/μL (IQR 63–291) in 2013. Older age and male sex were associated with late presentation across the ten-year period. The probability of ART initiation by six months after enrolment increased from 22.6% in 2003–2006 to 79.9% in 2011–2013.

Conclusion
Although a gradual improvement was observed over time, a large proportion of patients still enroll late, particularly older or male patients. Interventions to achieve early HIV testing and efficient linkage to care are warranted.

Douching Practices among Female Sex Workers in Phnom Penh, Cambodia

Several studies indicate that douching has few benefits but numerous adverse health outcomes, including increased risk for sexually transmitted infections and HIV. No published study explores douching practices among Cambodian female sex workers. 

This report provides preliminary data about the prevalence and frequency of douching among female sex workers in Phnom Penh, Cambodia. Survey data were obtained from 81 female sex workers who were taken into custody due to engagement in commercial sex from March to June 2011. 

Results showed that 91% of participants douched. The mean numbers of times douched before sex and after sex per 10 sex episodes were 4.43 (SD = 3.87) and 4.63 (SD = 3.94), respectively. Half of the participants thought that douching could help to prevent sexually transmitted infections including HIV; 24% were unsure about this. 

Usually, douching after sex was associated with ever obtaining an HIV test and was marginally associated (although not statistically significant) with a higher average number of clients per week and consistent condom use with clients. This suggests that these practices may be related to individual perceptions of sexually transmitted infections/HIV risk or susceptibility. 

Given the commonness of douching and related misperceptions among Cambodian female sex workers, future studies and interventions are needed to prevent adverse health problems.

Factors Associated with Induced Abortion among Female Entertainment Workers: A Cross-Sectional Study in Cambodia

OBJECTIVE:
To explore risk factors associated with induced abortion among sexually active female entertainment workers (FEWs) in Cambodia.

PARTICIPANTS:
This study included 556 FEWs aged 18-47 years randomly selected from entertainment establishments in the two cities in 2014 using a two-stage cluster sampling method. Data were collected through face-to-face interviews using a structured questionnaire.

RESULTS:
Of the total sample, 45.6% reported currently using a contraceptive method with condom (42.4%) being the most common method, followed by pills (25.6%). One-fourth (25%) of the respondents reported having been pregnant at least once, and 21.4% reported having at least one induced abortion during the time working as a FEW. After controlling for other covariates in a multivariate logistic regression model, FEWs with a history of induced abortion remained significantly more likely to be currently working in a karaoke bar, to have worked longer as a FEW, to have had a greater number of sexual partners in the past 12 months, to be currently using a contraceptive method, to be able to find condoms when they needed them, and to report inconsistent condom use with non-commercial partners in the past 3 months.

CONCLUSIONS:
This study highlights the high rates of unwanted pregnancies that ended in induced abortions among FEWs in Cambodia. Access of FEWs to quality sexual and reproductive healthcare services is deemed a high priority. Integrated interventions to improve sexual and reproductive health among these vulnerable women should be tailored to reach the most-at-risk groups.

Conflicting Rights: How the Prohibition of Human Trafficking and Sexual Exploitation Infringes the Right to Health of Female Sex Workers in Phnom Penh, Cambodia

While repressive laws and policies in relation to sex work have the potential to undermine HIV prevention efforts, empirical research on their interface has been lacking. In 2008, Cambodia introduced antitrafficking legislation ostensibly designed to suppress human trafficking and sexual exploitation

Based on empirical research with female sex workers, this article examines the impact of the new law on vulnerability to HIV and other adversehealth outcomes. Following the introduction of the law, sex workers reported being displaced to streets and guesthouses, impacting their ability to negotiate safe sex and increasing exposure to violence. Disruption of peer networks and associated mobility also reduced access to outreach, condoms, and health care. 

Our results are consistent with a growing body of research which associates the violation of sex workers' human rightswith adverse public health outcomes. Despite the successes of the last decade, Cambodia's AIDS epidemic remains volatile and the current legal environment has the potential to undermine prevention efforts by promoting stigma and discrimination, impeding prevention uptake and coverage, and increasing infections. Legal and policy responses which seek to protect the rights of the sexually exploited should not infringe the right to healthof sex workers.

Pharmacology, Physiology & Performance: Occupational Drug Use & HIV Risk among Female Entertainment & Sex Workers in Cambodia

In Cambodia, HIV prevalence among female entertainment and sex workers (FESW) is up to twenty times higher than in the general population. Use of amphetamine-type stimulants (ATS) has been associated with increased risk of HIV and other sexually transmitted infections in key populations, including FESW. While one in four Cambodian FESW report recent ATS use, little attention has been paid to how the occupational contexts of sex work shape patterns of use. Currently, no HIV prevention interventions target ATS use in this population.

We conducted in-depth interviews with FESW (n = 30) with the goal of exploring experiences and motivations for ATS use and informing the development of a conditional cash transfer (CCT) intervention designed to reduce ATS use and HIV risk. Interviews were conducted and transcribed in Khmer and translated into English. Interview narratives were read and re-read and emerging themes reviewed and refined to develop an initial coding scheme. Data were formally coded using both open and axial coding to clarify and consolidate initial themes.

The most common driver of ATS use among FESW was increased functionality. ATS was seen as a performance enhancer, acting as an appetite suppressant and enabling women to meet the physiological demands of sex work, including long working hours, multiple clients and extended sexual transactions. While our results are consistent with studies linking ATS use to heightened sexual risk, via unprotected and/or prolonged sex, for women in the current study, the negative consequences of ATS use were outweighed by perceived functional benefits.

FESW in Cambodia harness the pharmacological properties of ATS to meet the physiological demands of sex work in a context of limited economic opportunities. There is an urgent need to both provide Cambodian women with options for income generation that do not risk their health and to better regulate the conditions of sex work to provide safer working environments. Structural and economic interventions, including CCT programmes, combined with awareness and enforcement of sex workers’ rights, are also necessary to facilitate harm reduction and occupational health and work safety within the Cambodian sex and entertainment industry...

Participants highlighted the salience of ATS in the context of sex and entertainment work. Women reported using ATS for occupational performance—to stay awake longer and to work more hours, enabling them to see more clients.
[M]ost importantly if we don’t use it, it makes us rather sleepy. We could not stand [solicit clients] feeling sleepy until dawn as we could earn no money (Vanna, 32 year-old FESW, Battambang).
For those who work in entertainment services, when we smoke it, we can earn money. How can we earn money? We can stand till dawn. Stand all night till dawn. It is up to us. When the substances are in our body we cannot sleep so we stand earning money (Rumdoul, 23 year-old FESW, Phnom Penh).
The reason is that I first separated from my husband and I don’t have money to support my children so I decided to do so because I don’t have energy to work at night then I have to use it (Channa, 20 year-old FESW, Phnom Penh).
ATS were valued for their pharmacological properties, primarily the inducement of insomnia and increased energy or strength. Outside the occupational setting and without this functional purpose, women indicated that they were less likely to use ATS.
I use it a little not to feel sleepy so that I can earn money to support my children. Most importantly, I am happy as I sleep with my children at home. I ate rice. I went to the market to buy clothes for my children. This makes me happy (Sopha, 32 year-old FESW Battambang).
Sometimes we don’t have enough power so no matter how much we use it [yama] we must sleep. At that time we could not have more sex, so we don’t use it when we could not have more sex because we would waste our money. We just sleep to gain power and eat fully and wait until the time we earn money and we use it then we have power (Chorphum, 30 year-old FESW, Banteay Meanchey).
While insomnia, increased energy and endurance were not seen as functional outside the workplace, within the context of sex work functionality, the performance-enhancing aspects of ATS were the most commonly mentioned motivations for use.
[S]ometimes when we don’t smoke it, we can’t earn money. When we smoke it, we don’t feel sleepy, then we can work… [W]e just want to smoke it to earn money (Chorvy, 22 year-old FESW, Phnom Penh).
I used it not to feel sleepy as I sought to work overtime only to earn more money (Mala, 20 year-old FESW, Siem Reap)...

Characteristics, Risk Behaviors & Factors Associated with Abortion among Female Entertainment Workers in Cambodia

Background

Linkages between HIV and reproductive health (RH) among female entertainment workers (EWs) have not been addressed well in most developing countries. In Cambodia, there has been considerable research on HIV epidemiology among EWs. However, there have been limited studies on RH and specifically factors related to abortion. We examine socio-behavioral characteristics, and RH practices as determinants of abortion among Cambodian EWs.

Methods

A survey was conducted in Siem Reap and Battambang and Phnom Penh provinces/city among EWs in September 2012. Trained female interviewers administered the survey to 595 EWs. Two-stage cluster sampling was used to select EWs. Bivariate associations were examined using chi-squares; univariate and multivariate logistic regression were used to assess factors independently associated with reporting having at least one abortion while working as an EW.

Results

Three-quarters (75 %) of EWs were sexually active, of which nearly one third reported at least one abortion while working as an EW. About 40 % of EWs reported recent an abortion in the past six months. Contraceptive use in the past year was low. Factors found to be independently associated with reporting a recent abortion included: ages 25–29 (OR = 2.2, 95 % CI: 1.2–4.0), living with spouse/cohabitated partner (OR = 2.2, 95 % CI: 1.1–4.2), longer duration of entertainment work (OR = 4.8, 95 % CI: 2.5–9.2), higher number of partners (OR = 4.4, 95 % CI: 2.2–8.7) and being a karaoke worker (OR = 2.2, 95 % CI: 1.1–4.4).

Conclusion

This study highlights a high proportion of EWs reporting abortion. While HIV vulnerability of EWs has been clearly established, broader RH needs have gone largely unrecognized and not prioritized. Though HIV/RH integrated initiatives have been introduced by the HIV program, challenges for EWs with multiple risks from professional and partners are profound. Therefore, there is an urgent need for practical programmatic approaches to help address their RH needs.
