Abstract

Young male sex workers (YMSWs) in Vietnam have high rates of HIV and STIs, yet have poor access to health care due to low knowledge, stigma, and economic constraints. In the process of implementing a Sexual Health Promotion intervention to engage YMSWs in Ho Chi Minh City in health care, we identified a unique sex work venue, known as a “Shared House,” in which YMSWs 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 YMSWs 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 public places. However, observational data and informal interviews with YMSWs in Shared Houses revealed that the majority were trafficked through third-party brokers who connect youth with Shared House managers for the explicit purpose of sex work. These YMSWs had little or no control over their sex-work transactions and very low levels of knowledge regarding transmission of HIV and STIs. Further research is needed in these and other venues in which young men are trafficked for sex work.

Abstract

Background This article reports on the first web-based implementation of an opioid-overdose prevention, recognition and response training for professional first responders. The training was disseminated nationally over one listserv in November 2014. The same year, following Act 139, which mandated the provision of an online training for police officers in Pennsylvania, the Pennsylvania Department of Health approved the training. It was subsequently adopted as the primary training tool for police and other first responders in Pennsylvania and has been used as a training tool by first responders nationally. Methods Analyses employed descriptive statistics to report characteristics of a sample of 387 professional first responders who completed a survey about their experience with the online training. Z-ratios were used to compare independent proportions related to overdose, naloxone, and satisfaction with the training between key subgroups, and paired t-tests were used to compare participant responses to a range of items pre- and post-participation in the training. Results Between January–October 2015, 4804 first responders took the training; 1697 (35.3%) agreed to be contacted; of these, 387 (22.8%) completed a survey about the training and subsequent overdose response experiences. The majority (86.4%) were from Pennsylvania, with police representing over half of the sample. Analysis of the post-training survey indicates high satisfaction with content, format and mode of delivery, and high satisfaction with items related to confidence and overdose reversal preparedness. Conclusions This study demonstrates the feasibility and acceptability of implementing online training for first responders in overdose prevention, recognition and response.

Abstract

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). LCA clustered participants into recent drug use groups, incorporating both the specific types and overall count of different drugs used. Men reported drug use within a 1 month period from an 11-item drug use list. LCA identified three distinct drug use classes: (1) alcohol use, (2) alcohol and tobacco use, and (3) high polydrug use. The current drug use classes are associated with sex worker status, housing stability, income level, educational attainment, marital status, sexual identity, and sexual preferences. High levels of drug use are strongly associated with being a recent sex worker, not having recent stable housing, higher than median income, more than a high school education, less likely to be currently in school and more likely to have non-homosexual preferences and heterosexual partners. An event history analysis approach (time-event displays) examined the timing of the age of onset of drug and sexual risks. Early ages of drug and sexual initiation are seen for all three classes. High current drug users show earlier onset of these risks, which are significantly delayed for moderate and low current drug users. LCA incorporating an overall count of different drugs detected three distinct current drug use classes. The data illustrates that the complexity of drug factors that must be accounted for, both in advancing our epidemiological understanding of the complexity of drug use and the use of drug and sexual risk initiation data to predict current drug use subtypes among high-risk populations.

Abstract

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). Results: YMSW reported high levels of satisfaction with each of the seven core modules within the intervention and for the intervention as a whole. The intervention conferred significant benefit in relation to improved knowledge of STI and HIV transmission (P<0.001). Although only 36% of participants had seen a healthcare provider in the past year, following the intervention 81% intended to see one in the next 6 months. Similarly, although 71% of participants did not disclose that they were MSM the last time they visited a healthcare provider, following the intervention 71% intended to do so at their next visit. High rates of STIs (>10%) and HIV (9.5%) were also found. Conclusion: The data show that the SHEATH intervention can be implemented in this population and setting, is met with high rates of acceptability, and positively impacts STI and HIV knowledge and multiple health services outcomes (including knowledge of HIV status and disposition towards habituation of HIV screening).

Abstract

Young men who have sex with men (YMSM) younger than 18 years are often excluded from HIV prevention research in Thailand due to cultural attitudes toward youth sexuality, social stigma, and difficulties obtaining guardian permission. Culturally sensitive focus group discussions conducted with parents and YMSM in Bangkok, Thailand, identified barriers and facilitators related to minors’ participation in HIV prevention research. Although gender and class differences emerged, mothers and fathers were generally accepting of research to reduce HIV risk but not in favor of waiver. Youth’s positive attitude toward parental permission was tempered by concerns about harms posed by disclosing same-sex attraction through permission forms.

Abstract

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. Variability was seen in both injection and sexual risk, with 12.9% of current injectors reporting at least one unsafe method of drug sharing and 57.1% reporting unsafe sex in the past 30 days. These risks were strongly associated with those who engaged in unsafe injection significantly more likely to engage in unsafe sex (69.4% vs. 55.3%) and those engaging in unsafe sex significantly more likely to engage in unsafe injection (15.7% vs. 9.2%). These findings highlight the overlap of injection and sexual risk practices among Vietnamese heroin users and suggest the need for strong, broadly targeted HIV prevention activities among this population.

Abstract

ABSTRACT. Objectives: This study assessed depression and anxiety symptoms and their association with high-risk sexual and drug behaviors among male sex workers in 3 Vietnamese cities. Methods: Male sex workers ages 16 to 35 years old completed an interview that included the Center for Epidemiological Studies Depression Scale to assess depressive symptoms and the Beck Anxiety Inventory to assess anxiety symptoms, as well as questions assessing drug and sexual risk practices. Results: A majority of participants reported depressive symptomatology, although fewer reported symptoms of anxiety. Risky sexual and drug use practices predicted both types of symptoms. Conclusions: Mental distress is associated with drug and sexual risk among male sex workers.

Abstract

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. Subjects were screened for STIs, including HIV. Results: MSWs in Ho Chi Minh City (33%) were more likely than those from the other two sites to be current users of one or more types of illegal drugs (P<0.001). MSWs with both male and female elective partners (compared with other partnership types) were more likely to have anal sex with male client partners (P<0.001), elective male partners (P≤0.045) and elective female partners (P≤0.025). At last sex with a male client partner, only 30% used a condom during anal intercourse. At last sex with an elective female partner, only 31% used a condom during vaginal sex and only 3% during anal sex. Although rates of HIV are low (4%), other STIs are high, including chlamydia (17%), gonorrhoea (29%) and human papillomavirus (33%). Most (57.3%) have never been tested for HIV and only 17% have ever disclosed to a healthcare provider that they have sex with men. Conclusions: Complex patterns of sexual concurrency, coupled with high rates of STIs, signal the urgent need for health services interventions among MSWs, both to improve individual health outcomes and to reduce secondary STI/HIV transmission among sexual partner networks.

Abstract

Background: HIV research in Vietnam has focused primarily on its large heroin injector population. Data on men who have sex with men [MSM], particularly the large and growing population of men who exchange sex for money or other material rewards, male sex workers [MSWs], is very limited. Methods: Data derive from a cross-sectional study of MSW, age 16-35, recruited using community sampling methods in three cities in 2010-2011, including Hanoi, Ho Chi Minh City [HCMC], and Nha Trang City (n=710). Assessments included demographic characteristics, substance use, sexual risk, and use of health services. A series of "event" questions were used to assess the influence of alcohol and drugs on sexual risk. Results: Both tobacco and alcohol are initiated at a young age and most participants currently use both substances overall across all three cities. While alcohol and tobacco use precede the initiation of sex work, stimulant and opiate use are initiated following the initiation of sex work. There was substantial overlap between substance use and sexual risk, and this overlap was strongest in sexual events involving male and female elective partners rather than sex work clients. Conclusion: Although rates of HIV infection in this group are low, this may be an artifact of the young age of the sample. High rates of drug use, including alcohol, tobacco and illicit drugs, coupled with high rates of ulcerative STIs such as HPV, suggest the potential for rapid amplification of STI/HIV risk among MSW and their complex sex partnering networks.
