Heavy Alcohol Use Among Migrant and Non-Migrant Male Sex Workers in Thailand: A Neglected HIV/STI Vulnerability.

Background: There is scarce research on male sex workers in the context of alcohol use. While heavy alcohol use has been established as a risk factor for HIV and STI infections among men who have sex with men (MSM), men who engage in sex work with other men, particularly from the Global South, have not been included in these studies. Moreover, studies among male sex workers in Asia often do not explore migration contexts of these men.

HIV and other STIs in male sex workers: Findings from a sexual health promotion intervention in Vietnam.

Male sex workers (MSWs) in Vietnam are at high risk for acquisition and transmission of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs), yet are extremely disengaged from the healthcare system. This contributes to large numbers of untreated or late-treated infections and increased secondary transmission. We enrolled 995 MSWs in Hanoi and Ho Chi Minh City (HCMC) in a Sexual Health Promotion intervention that included face-to-face delivery of seven content modules, a clinical examination and testing for HIV, syphilis, gonorrhea and Chlamydia.

Human Trafficking and Emerging Sex Risk Environments in Vietnam: A Preliminary Profile of a Sex Work "Shared House".

Young male sex workers (YMSW) in Vietnam have high rates of HIV and STIs, yet have poor access to healthcare due low knowledge, stigma, and economic constraints. In the process of implementing a Sexual Health Promotion intervention to engage YMSW in Ho Chi Minh City in healthcare, we identified a unique sex work venue, known as a "Shared House," in which YMSW provide sex under the direction of a manager who negotiates the terms of the transaction directly with the client. Survey data reveal that compared with YMSW recruited in other locations, those interviewed in Shared Houses reported lower levels of substance use, less contact with the police, and fewer nights spent sleeping in pubic places.

Sexually transmissible infection and HIV prevention and treatment for young male sex workers in Vietnam: findings from the SHEATH intervention.

Unlabelled: Background Urban centres in Vietnam have high rates of HIV infection, especially among men who have sex with men (MSM). A subgroup of MSM, young male sex workers (YMSW), are at especially high risk due to concurrent sex with multiple male and female partners, low levels of knowledge regarding HIV and sexually transmissible infection (STI) transmission, and limited engagement with health services, including STI and HIV screening and treatment.

Methods: A targeted intervention (SHEATH) derived from Harm Reduction and Sexual Health Promotion intervention technology was implemented in an out-of-treatment population of YMSW in Hanoi and Ho Chi Minh City (n=919).

Sexual Initiation and Complex Recent Polydrug Use Patterns Among Male Sex Workers in Vietnam: A Preliminary Epidemiological Trajectory.

Little is known about the age of onset of sexual and drug risk and their association with complex patterns of recent drug use among male sex workers (MSW) in a developing country, such as Vietnam. The aim of this study was to determine whether latent class analysis (LCA) would aid in the detection of current individual and polydrug use combinations to predict how different trajectories of sexual and drug initiation contribute to different patterns of current illicit drug use. Data were collected from a cross-sectional survey administered to young MSWs between 2010 and 2011 in Vietnam (N = 710).

Injection and sexual risk practices among young heroin users in Hanoi, Vietnam.

Epidemiological data in Vietnam shows high HIV prevalence rates among injection drug users, especially in urban centres. However, there are limited data on specific practices used to prepare and inject drugs or on sexual practices among Vietnamese injectors. A street-based cross-sectional interview was conducted with 862 heroin injectors in Hanoi, Vietnam, to collect such data.

Prevalence and Behavioral Correlates of Depression and Anxiety Among Male Sex Workers in Vietnam.

Objectives: This study assessed depression and anxiety symptoms, and their association with high-risk sexual and drug behaviors, among male sex workers in three Vietnamese cities.

Methods: Male sex workers ages 16 to 35 completed an interview that included the CES-D to assess depressive symptoms and the BAI to assess anxiety symptoms, as well as questions assessing drug and sexual risk practices.

Results: A majority of participants reported depressive symptomatology although fewer report symptoms of anxiety.

Sexual practices, partner concurrency and high rates of sexually transmissible infections among male sex workers in three cities in Vietnam.

Unlabelled: Background This paper examines sexual practices, partner concurrency and sexually transmissible infections (STI)/HIV infection among male sex workers (MSWs) in Vietnam.

Methods: Six hundred and fifty-four MSWs, aged 16-35 years, were recruited in Hanoi, Nha Trang and Ho Chi Minh City between 2009 and 2011. Survey measures included demographic characteristics, drug use, types of sexual partners and sexual practices.

Health care practices and associated service needs in a sample of HIV-positive incarcerated men in Puerto Rico: implications for retention in care.

Objective: This report describes the HIV-related health care practices and associated support service needs of a sample of HIV-positive incarcerated men in Puerto Rico.

Methods: Data are derived from a random sample of HIV-positive incarcerated men (n = 37) in Puerto Rico who completed a brief survey. Analysis included descriptive statistics to examine lifetime prevalence of substance use, selected health care practices, receipt of services, and hepatitis C virus (HCV) infection.

Epidemiology of anal HPV infection in high-risk men attending a sexually transmitted infection clinic in Puerto Rico.

Purpose: Recent studies in Puerto Rico have reported an increasing incidence of anal cancer in Puerto Rican men. The objective of this study was to determine the prevalence, genotype distribution and risk factors associated with anal HPV infection among men attending an STI clinic in Puerto Rico.

Methods: We conducted a cross-sectional study among 205 men 18 years and older.

Awareness and knowledge of human papillomavirus (HPV) infection among high-risk men of Hispanic origin attending a sexually transmitted infection (STI) clinic.

Background: Genital human papillomavirus (HPV) is one of the most commonly diagnosed sexually transmitted infection (STIs) in men and women. Knowledge about HPV infection among men is limited. This study aims to determine correlates of adequate knowledge of HPV infection among men who attend an STI clinic in Puerto Rico.

A preliminary profile of HIV risk in a clinic-based sample of MSM in Puerto Rico: implications for sexual health promotion interventions.

Objective: Puerto Rico has one of the fastest growing HIV epidemics in the United States and--consistent with patterns observed in the Caribbean region as a whole--data on new infections shows the increased influence of sexual transmission in the local epidemic. Historically, both epidemiology and prevention activities have focused primarily on the islands' large heroin injector population. Although the available surveillance data indicate high rates of STIs and HIV among men who have sex with men (MSM), there has been little social and behavioral research among MSM and hence little empirical information to inform intervention development and planning.

More than foreskin: circumcision status, history of HIV/STI, and sexual risk in a clinic-based sample of men in Puerto Rico.

Introduction: Circumcision among adult men has been widely promoted as a strategy to reduce human immunodeficiency virus (HIV) transmission risk. However, much of the available data derive from studies conducted in Africa, and there is as yet little research in the Caribbean region where sexual transmission is also a primary contributor to rapidly escalating HIV incidence.

Aim: In an effort to fill the void of data from the Caribbean, the objective of this article is to compare history of sexually transmitted infections (STI) and HIV diagnosis in relation to circumcision status in a clinic-based sample of men in Puerto Rico.

Sexually transmitted infections clinics as strategic venues for targeting high risk populations for HIV research and sexual health interventions.

Puerto Rico has one of the highest incidence rates of HIV in the U.S. Concurrent with increases in sexually transmitted infections (STI), an increasing share of the new infections in PR are associated with sexual transmission.

Preliminary Evidence of Significant Gaps in Continuity of HIV Care among Excarcerated Populations in Puerto Rico.

Objective: Puerto Rico has high HIV prevalence and incidence rates, including a large prison population living with HIV. While HIV treatment is available within the prisons, there are no linkages to care or treatment preparedness interventions following release.

Methods: In an effort to assess the risk of treatment discontinuity in this group, we examined data from an ongoing epidemiological study in the largest, publicly funded HIV/sexually transmitted infection (STI) treatment center in the San Juan area.

Prevalence of sexually acquired antiretroviral drug resistance in a community sample of HIV-positive men who have sex with men in New York City.

To examine antiretroviral (ARV) drug resistance, we recruited a community sample (n=347) of sexually active HIV-positive men who have sex with men (MSM) in New York City, each of whom completed a structured interview and donated a blood sample for HIV genotyping. Participants reported high levels of sexual activity, with 94.6% reporting at least one sexual contact in the past month, and an average of 3.

Accelerated transition to injection among male heroin initiates in Hanoi, Vietnam: implications for early harm reduction interventions.

This paper examines changes in the interval between first heroin smoking and onset of injection in a large, out-treatment sample of male heroin users in Hanoi, Vietnam (n = 1,115). Mean age at initiation of heroin use (smoking) was 18.4 and mean age of onset of heroin injection was 20.

Prevalence and incidence of HCV infection among Vietnam heroin users with recent onset of injection.

HCV infection continues to spread at an alarming rate among IDU populations. The available evidence suggests that HCV is acquired relatively quickly following onset of injection. However, there are few prospective studies of HCV acquisition, particularly among IDU populations in resource-poor settings.

New injectors and the social context of injection initiation.

Background: Preventing the onset of injecting drug use is an important public health objective yet there is little understanding of the process that leads to injection initiation. This paper draws extensively on narrative data to describe how injection initiation is influenced by social environment. We examine how watching other people inject can habitualise non-injectors to administering drugs with a needle and consider the process by which the stigma of injecting is replaced with curiosity.

Male sex work and HIV risk among young heroin users in Hanoi, Vietnam.

The present study describes complex drug and sexual risk in a group of male sex workers (n = 79) who were recruited in the context of a larger study of young heroin users in Hanoi, Vietnam (n = 1270). Male sex workers were significantly more likely than male non-sex workers to be migrants (P < 0.001) and to have unstable housing (P < 0.
