Factors associated with violence against female sex workers in ten Brazilian cities

Gender-Based Violence and Factors Associated with Victimization among Female Entertainment Workers in Cambodia: A Cross-Sectional Study

Women working in the entertainment industry are confronted with various forms of gender-based violence (GBV). However, their vulnerability remains understudied, particularly in resource-limited settings. This study aims to examine the prevalence of GBV among female entertainment workers (FEWs) in Cambodia and identify factors associated with victimization. We conducted a cross-sectional study in November 2018 for the impact evaluation of a randomized controlled trial. We used a stratified random sampling method to recruit 600 FEWs from different entertainment venues in the capital city and three other provinces. Female data collectors administered a structured questionnaire, and we performed multiple logistic regression analyses. Of the total, 60.5% had experienced a form of GBV during their lifetime; of whom, 37.5% experienced the GBV in the past 6 months. The prevalence of emotional abuse, forced substance use, physical abuse, and forced sex was 51.5%, 25.0%, 20.6%, and 2.9%, respectively. Forced substance use and forced sex were mainly perpetrated by clients, physical abuse by intimate partners, and emotional abuse by others such as entertainment establishment owners or managers. FEWs victimized by clients (relative risk ratio [RRR] = 0.19, 95% confidence interval [CI] = [0.07, 0.53]) and others (RRR = 0.11, 95% CI = [0.03, 0.44]) were less likely to be married compared with victims of intimate partner violence. Factors associated with sexual harassment were working in beer gardens (adjusted odds ratio [aOR] = 2.39, 95% CI = [1.20, 4.73]) and restaurants/cafés (aOR = 1.65, 95% CI = [1.01, 2.69]), and having higher acceptance of violence against women (aOR = 1.12, 95% CI = [1.01, 1.24]). FEWs in Cambodia experience high levels and unique forms of GBV as they are confronted with different types of perpetrators. Interventions need to be tailored to fit the specific needs of FEWs. Interventions aimed at reducing client-perpetrated violence should specifically focus on forced substance use and forced sex, while physical abuse by intimate partners should also be addressed.

Determinants and consequences of heavy episodic drinking among female sex workers in Ethiopia: A respondent-driven sampling study

Background

Female sex workers (FSW), due to their working conditions, have an increased likelihood of heavy episodic drinking (HED), which is associated with risky sexual behavior. Nevertheless the specific contribution of HED to risky sexual behavior among FSWs in Ethiopia is not well documented for prevention activities.

Objective

The purpose of this study was to explore the determinants and consequences of HED among FSWs in Ethiopia.

Methods

A cross-sectional study using respondent-driven sampling was conducted among 4886 FSWs in 11 major towns in Ethiopia in 2014. A structured interview was performed, and data were examined using descriptive statistics and multiple logistic regression analyses.

Results

Most (66%) FSWs consumed alcohol, and the prevalence of HED was 29.1%. Compared to street-based FSWs, those who worked in bars/hotels and local drinking houses had 2.19 and 1.29 times higher odds of HED, respectively. FSWs who started selling sex when younger than 18 years (compared to those who started when older than 25 years) and those who were forced into selling sex had 1.48 and 2.91 times higher odds of HED, respectively. FSWs with more income from selling sex and FSWs who chewed khat reported increased odds of HED. Moreover, FSWs with experience of HED reported 1.27 and 1.44 times higher odds of physical beating and condom breakage/slippage, respectively. Furthermore, the population attributable risk fraction of HED among FSWs showed that 6.2% of physical beating and 8.9% of condom breakage/slippage could be attributed to HED.

Conclusion

In general, several factors increase the experience of HED, and HED in turn increases the likelihood of violence and condom breakage. These factors could inform programs and intervention activities among FSWs populations.

Female Sex Workers' Experiences of Violence and Substance Use on the Haitian, Dominican Republic Border

Background

Female sex workers (FSW) are socially and economically marginalized, and this vulnerability can be exacerbated when they hold the intersectional identity of also being an immigrant, such as in the case of Haitian FSWs in the Dominican Republic.

Objective

Considering that half of migratory young women and girls relocating across the Latin American and Caribbean region do so without their families, increasing the likelihood of experiencing abuses, our primary objective was to test the hypothesis that Haitian FSWs in the Dominican Republic have higher odds of being physically abused by sexual partners compared to Haitian FSWs in Haiti.

Methods

We conducted bivariate analyses and multivariate analyses on 2014 Hispaniola Sex Workers Study (N = 232).

Findings

Approximately 80% of Haitian FSWs in the Dominican Republic reported experiencing violence by a regular partner (80.3%), compared with 60.0% of Haitian FSWs in Haiti (χ2 = 11.34, p < 0.001). Controlling for socio-demographics, substance use, childhood abuse, and sexual behaviors, Haitian FSWs in Haiti maintained lower odds of experiencing violence by a regular partner (OR:0.37, p < 0.01) and higher odds of experiencing violence from a coworker (OR:6.38, p < 0.001) compared to FSWs in the Dominican Republic. Using sex to avoid arrest is associated with higher odds of experiencing violence by a client and violence by a coworker (OR:2.18, p < 0.05; OR:3.74, p < 0.001; respectively). Accepting payment in the form of drugs/alcohol is associated with higher odds of experiencing physical violence by a regular partner but lower odds of experiencing violence by a client (OR:3.99, p < 0.05; OR:0.43, p < 0.05; respectively).

Conclusions

Assuming health is a human right, then practitioners and scholars must actively collaborate to fortify vulnerable populations against injurious structural and sociocultural forces examining the intersectionality and compound effects of multiple stigmatized identities, in this study being an FSW and an immigrant, that moderate the potential positive effects of public health interventions.

Unweighted regression models perform better than weighted regression techniques for respondent-driven sampling data: results from a simulation study

Background

It is unclear whether weighted or unweighted regression is preferred in the analysis of data derived from respondent driven sampling. Our objective was to evaluate the validity of various regression models, with and without weights and with various controls for clustering in the estimation of the risk of group membership from data collected using respondent-driven sampling (RDS).

Methods

Twelve networked populations, with varying levels of homophily and prevalence, based on a known distribution of a continuous predictor were simulated using 1000 RDS samples from each population. Weighted and unweighted binomial and Poisson general linear models, with and without various clustering controls and standard error adjustments were modelled for each sample and evaluated with respect to validity, bias and coverage rate. Population prevalence was also estimated.

Results

In the regression analysis, the unweighted log-link (Poisson) models maintained the nominal type-I error rate across all populations. Bias was substantial and type-I error rates unacceptably high for weighted binomial regression. Coverage rates for the estimation of prevalence were highest using RDS-weighted logistic regression, except at low prevalence (10%) where unweighted models are recommended.

Conclusions

Caution is warranted when undertaking regression analysis of RDS data. Even when reported degree is accurate, low reported degree can unduly influence regression estimates. Unweighted Poisson regression is therefore recommended.

Sex work stigma and non-disclosure to health care providers: data from a large RDS study among FSW in Brazil

Background

Stigma in health services may be detrimental to health seeking attitudes and practices. This study investigates non-disclosure of sex work to health care providers among female sex workers (FSW) in Brazil and its association with the utilization of health care services.

Methods

This study used cross-sectional respondent-driven sampling, carried out in 12 Brazilian cities to identify HIV risk behaviors among FSW. We first assessed statistical associations of sociodemographic, human right violations, health service access and utilization, and discrimination variables with non-disclosure of FSW status to health care providers as outcome. Secondly, we investigated the association of non-disclosure of FSW status with selected preventive health care outcomes: HIV testing, PAP smear exam, and post-exposure prophylaxis (PEP). Adjusted odds ratio with 95% confidence intervals were calculated by multivariable logistic regressions.

Results

Among 4245 recruited FSW, a high percentage received free condoms (82%) but only 24.4% were counseled on STI. Most FSW used non-specialized public healthcare routinely (62.6%), but only 51.5% had a Pap smear exam in the last two years and less than 40% were tested for HIV in the last 12 months. Among FSW who engaged in risky behavior (49.6%), only 8.3% used PEP. Regarding human rights violations, approximately 15% were required to give part of their earnings to owners of workplace establishments, 38% started sex work under 18 years old and 6% were required to periodically present their HIV test results. 21.3% reported having faced discrimination in health services, and 24.3% always disclosed their FSW status. Multivariable logistic models indicated significant associations of non-disclosure on the four healthcare outcomes, with lower odds of using preventive health services among women who did not disclose their sex work status, even after controlling for age, educational level, NGO affiliation, and type of health care routinely used.

Conclusions

Our results indicate that sex work stigmatization within health services may be one of the main barriers to STI control and HIV response among FSW. It is essential to combat stigmatization and discrimination against FSW in health services to guarantee the appropriate uptake of preventive services available in the public health system in Brazil.

Prevalence estimates of HIV, syphilis, hepatitis B and C among female sex workers (FSW) in Brazil, 2016

BACKGROUND

Female sex workers (FSW) bear a high burden of sexually transmitted infections (STI). In this paper, we estimate the prevalence of human immunodeficiency virus (HIV), HBV = hepatitis B virus (HBV), HCV = hepatitis C virus (HCV), syphilis and co-infections in the second Biological and Behavioral Surveillance Survey among FSW in Brazil.

METHOD

The survey was conducted in 12 Brazilian cities from July to November 2016. We used respondent-driven sampling (RDS) to recruit 350 FSW in each city. Rapid tests were used for screening HIV, syphilis, HCV, and HBV. Confirmatory tests were performed on all samples with reactive rapid test result. All testing algorithms and interpretations were done according to the recommendations of the Department of STI/AIDS and viral hepatitis, Ministry of Health. The STI diagnoses were given by: confirmed HIV infection by a positive result on Western blot; active syphilis infection, defined by a RPR titer equal or greater than 1/8; viremia period of HBV and HCV infections, characterized by a detectable (or quantifiable) viral load. Prevalence estimates and standard errors were calculated using statistical procedures suitable for data collected by RDS.

RESULTS

Excluding the seeds, 4245 FSW were enrolled. Prevalence estimates were: HIV 5.3% (95% CI: 4.4%-6.2%); active syphilis 8.5% (95% CI: 7.3%-9.7%); HBV 0.4% (95% CI: 0.2%-0.7%); and, HCV 0.9% (95% CI: 0.6%-1.3%). Among the 4154 FSW tested for the 4 infections, 13.3%; (95% CI 12.0%-14.8%) were diagnosed with at least one of the infections, of which 87.6% (95% CI: 83.3%-90.9%) had single infections. The prevalence of HIV/syphilis co-infection was 1.09% (95% CI: 0.7%- 1.6%) and of HIV/HCV or HBV infections was 0.4% (95% CI: 0.2%-0.7%).

CONCLUSIONS

Our results reveal the need to conduct more studies to estimate the prevalence of STI and co-infections among FSW in Brazil. Longitudinal trends in the prevalence estimates of HIV and other STI provide information to monitor changes in this high-risk population. Additionally, the study highlights the importance of measuring the hepatitis burden among FSW living with HIV, and the need of including FSW in all aspects of STI prevention, care, and treatment programs.

Factors associated with HIV infection among female sex workers in Brazil

BACKGROUND

Female sex workers (FSWs) are one of the most-at-risk population groups for human immunodeficiency virus (HIV) infection. This paper aims at identifying the main predictors of HIV infection among FSW recruited in the 2nd Biological and Behavioral Surveillance Survey in 12 Brazilian cities in 2016.

METHOD

Data were collected on 4245 FSW recruited by respondent driven sampling (RDS). Weights were inversely proportional to participants' network sizes. To establish the correlates of HIV infection, we used logistic regression models taking into account the dependence of observations resultant from the recruitment chains. The analysis included socio-demographic sex work characteristics, sexual behavior, history of violence, alcohol and drug use, utilization of health services, and occurrence of other sexually transmitted infections (STIs).

RESULTS

HIV prevalence was estimated as 5.3% (4.4%-6.2%). The odds ratio (OR) of an HIV-positive recruiter choosing an HIV-positive participant was 3.9 times higher than that of an HIV-negative recruiter (P < .001). Regarding socio-demographic and sex work characteristics, low educational level, street as the main work venue, low price per sexual encounter, and longer exposure time as a sex worker were found to be associated with HIV infection, even after controlling for the homophily effect. The OR of being HIV infected among FSW who had been exposed to sexual violence at least once in a lifetime (OR = 1.5, P = .028) and the use of illicit drugs at least once a week were highly significant as well, particularly for frequent crack use (OR = 3.6, P < .001). Among the sexual behavior indicators, not using condoms in some circumstances were significantly associated with HIV infection (OR = 1.8, P = .016). Regarding the occurrence of other STI, the odds of being HIV infected was significantly higher among FSW with a reactive treponemal test for syphilis (OR = 4.6, P < .001).

CONCLUSIONS

The main factors associated with HIV infection identified in our study characterize a specific type of street-based sex work in Brazil and provided valuable information for developing interventions. However, there is a further need of addressing social and contextual factors, including illicit drug use, violence, exploitation, as well as stigma and discrimination, which can influence sexual behavior.
