High Frequency of Illegal Drug Use Influences Condom Use Among Female Transgender Sex Workers in Argentina: Impact on HIV and Syphilis Infections.

The high prevalence of HIV and syphilis found among female transgender sex workers (FTSWs) in Argentina calls for the study of factors leading to negative health consequences. Given the particular characteristics observed in this population (high marginalization, school dropout, and low adherence to healthcare services), we explored the association of several socio-demographic characteristics with syphilis and HIV infections, and the determinants of condom use. This study revealed that FTSWs from Argentina were exposed to several risk factors decreasing thus their ability to negotiate condom use and leading to increased risk for transmission of HIV and other sexually transmitted infections (STIs). Strategies to reduce HIV and syphilis in this population should consider interventions aimed at decreasing violence and substance use which appear to be the most important determinants. Results of this study will contribute to the global information among FTSWs.

[Prevalence of HIV infection and Treponema pallidum in Argentine female sex workers]. / Prevalencia de la infección por el VIH y de Treponema pallidum en mujeres trabajadoras sexuales de Argentina.

OBJECTIVE: Estimate the prevalence of human immunodeficiency virus (HIV) infection and Treponema pallidum in Argentine female sex workers (FSW), and describe the sociodemographic characteristics of this population group associated with HIV transmission. METHODS: A cross-sectional study and convenience sampling were conducted in FSW over 18 years of age in nine Argentine cities from October 2006 to December 2009. A total of 1 255 women participated in this study. A group of FSW was especially trained to invite other women to participate in the workshops and undergo screening for HIV and T. pallidum. RESULTS: The most noteworthy socioepidemiological characteristics of the FSW included a high percentage of sexual abuse, limited condom use with noncommercial sex partners, and a high percentage of violence. HIV prevalence was 2% (25/1 255, 95% confidence interval [95% CI]:1.2-2.8) and T. pallidum prevalence was 22.4% (245/1 094; 95% CI: 19.9-24.9). In the city of La Plata, HIV prevalence in FSW was significantly lower compared to that of other regions of the country (0.3% vs. 2.7%, P < 0.05, respectively). CONCLUSIONS: The lower HIV prevalence and the higher rate of condom use reported by the women from La Plata surveyed suggest that the presence of a health center for FSW has a direct influence on reducing risky behavior and, consequently, HIV infection. The creation of "friendly" health centers like the one already in this city contributes to providing a comprehensive response to the problems faced by these women and encourages use of the health system. It therefore helps reverse their vulnerability and higher risk of contracting HIV and other sexually transmitted infections.

Recognize sex work as legitimate work.

It is not sex work per se that makes sex workers vulnerable to HIV, but rather the policies that repress them. In this article, based on her presentation at a plenary session at the conference, Elena Reynaga, who is a sex worker, describes how these policies deprive sex workers of their rights and subject them to physical and sexual violence. The author concludes that at the heart of the problem lies the fact that sex work is not recognized as legitimate work.

Violence as a barrier for HIV prevention among female sex workers in Argentina.

BACKGROUND: Violence against female sex workers (FSWs) has been increasingly reported as an important determinant of HIV infection risk. This study explores the frequency of different violent experiences (sexual abuse, rejection, beating and imprisonment) among FSWs in Argentina and its association with condom use and HIV and T. pallidum prevalence. METHODS: A convenience sample of 1255 FSWs was included in a cross-sectional study conducted between October 2006 and November 2009. RESULTS: Sexual abuse was reported by 24.1% (219/907) of women. A total of 34.7% (42/1234) reported rejection experiences, 21.9% (267/1215) reported having been beaten and 45.4% (561/1236) stated having been arrested because of their sex work activity. There was a higher frequency of inconsistent condom use with clients among FSWs who had experienced sexual abuse, rejection, and police detention. A higher frequency of HIV and T. pallidum infection was detected among FSWs who reported having been arrested by the police. CONCLUSION: The study shows for the first time the frequency of different violent situations among FSWs in Argentina. The association between violence against sex workers, condom use and STI prevalence demonstrated here calls for measures to reduce stigma and violence against FSWs. Such violent experiences may increase vulnerability to STI through coerced unprotected sex.

First report on sexually transmitted infections among trans (male to female transvestites, transsexuals, or transgender) and male sex workers in Argentina: high HIV, HPV, HBV, and syphilis prevalence.

OBJECTIVES: Due to the scarce data on the prevalence of sexually transmitted infections (STIs) among male-to-female trans-sex workers (TSW) and male sex workers (MSW) in Argentina, the present study aimed to estimate the incidence of human immunodeficiency virus (HIV), and the prevalence of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and Treponema pallidum. Human papillomavirus (HPV) and Chlamydia trachomatis infections were tested among TSW. METHODS: Two hundred and seventy-three TSW and 114 MSW were recruited by nongovernmental organizations. HIV incidence was estimated by STARHS (serologic testing algorithm for recent HIV seroconversion). HPV and C. trachomatis infections were tested in anal cells from TSW. RESULTS: TSW showed significantly higher prevalences of HIV (34.1 vs. 11.4%), HBV (40.2 vs. 22.0%), and T. pallidum (50.4 vs. 20.4%) than MSW. TSW tested positive for HPV in 111/114 cases and for C. trachomatis in 4/80 cases. Investigation of HBV, HCV, HIV, and T. pallidum co-infections showed that 72% of TSW and 39% of MSW had at least one STI. T. pallidum was the most frequent mono-infection. The estimated HIV incidence was 10.7 per 100 person-years (95% confidence interval (CI) 3.8-17.7) for TSW and 2.3 per 100 person-years (95% CI 0-6.7) for MSW. CONCLUSIONS: The high prevalence of STIs and the high incidence of HIV demonstrate the great vulnerability of these high-risk populations and indicate the urgent need for preventive strategies on intervention and facilitation of access to healthcare programs.

Sexual practices, drug use behaviors, and prevalence of HIV, syphilis, hepatitis B and C, and HTLV-1/2 in immigrant and non-immigrant female sex workers in Argentina.

OBJECTIVE: To study socio-demographics, sexual practices, drug use behaviors, and prevalences of HIV, syphilis, hepatitis B and C, HTLV-1 and HTLV-2 in immigrant (foreigner) and non-immigrant (local/native) female sex workers (FSW). DESIGN: This was a cross-sectional study in immigrant and non-immigrant FSW living in Buenos Aires, Argentina. Participants were interviewed using a standardized questionnaire. RESULTS: A total of 625 FSW were enrolled, of whom 169 (27%) were immigrant FSW from Paraguay, the Dominican Republic, Brazil, Peru, and Uruguay. The prevalence of syphilis and hepatitis C was significantly higher among Argentinean FSW than among immigrant FSW. However, hepatitis B prevalence was higher among immigrant FSW. Adjusted risk factor analysis comparing immigrant FSW with Argentinean FSW indicated that marital status (single), occupation (none), fee per sex act (

Prevalencia de la infección por el VIH y de Treponema pallidum en mujeres trabajadoras sexuales de Argentina / Prevalence of HIV infection and Treponema pallidum in Argentine female sex workers

OBJETIVO: Estimar la prevalencia de infección por el virus de la inmunodeficiencia humana (VIH) y de Treponema pallidum en mujeres trabajadoras sexuales (MTS) de Argentina, y describir las características sociodemográficas de este grupo de población asociadas a la transmisión del VIH. MÉTODOS: Entre octubre de 2006 y diciembre de 2009 se realizó un estudio de corte transversal y un muestreo por conveniencia en MTS mayores de 18 años de nueve ciudades de Argentina. Un total de 1 255 mujeres participaron en este estudio. Se capacitó especialmente a un grupo de MTS para convocar a las otras mujeres a participar en talleres y a realizarse el diagnóstico del VIH y T. pallidum. RESULTADOS: Las características socio-epidemiológicas más destacadas de las MTS incluyeron un alto porcentaje de abuso sexual, escaso uso de preservativos con parejas sexuales no comerciales y un alto porcentaje de situaciones de violencia. La prevalencia del VIH fue de 2 por ciento (25/1 255, intervalo de confianza de 95 por ciento [IC95 por ciento]:1,2-2,8) y la de T. pallidum, de 22,4 por ciento (245/ 1 094, IC95 por ciento: 19,9-24,9). En las MTS de la ciudad de La Plata, la prevalencia del VIH fue significativamente más baja comparada con las participantes del resto del país (0,3 por ciento vs 2,7 por ciento, P < 0,05, respectivamente). CONCLUSIONES: La menor prevalencia del VIH y la mayor tasa de uso de preservativos informadas por las mujeres encuestadas de La Plata sugieren que la presencia de un lugar de atención sanitaria para MTS influye directamente en la disminución de sus conductas de riesgo y, por ende, en la infección por el VIH. La creación de centros de salud "amigables", como el que ya hay en dicha ciudad, contribuye a dar una respuesta integral al problema que enfrentan estas mujeres; asimismo, favorece su acercamiento al sistema de salud y contribuye así a revertir su situación de mayor vulnerabilidad y mayor riesgo frente al VIH y otras infecciones de transmisión sexual.
