HIV-Related Risk Behaviors Among Labor Migrants,Their Wives and the General Population in Nepal

Nepalese labor migrants and their wives are considered as at-risk populations for HIV infection. There may be a risk of HIV transmission from the labor migrant and their wives to the general population due to HIV-related risk behaviors, but so far empirical evidence to support this hypothesis is scarce. Therefore, this study was conducted to compare HIV-related risk behaviors between labor migrants, their wives, and males and females from the general population in the far-western region of Nepal. This was a cross-sectional study, in which structured face-to-face interviews were conducted with 261 male labor migrants, 262 wives of labor migrants, 123 males and 122 females from the general population. We found that the proportion of the labor migrants and their wives reporting having had extramarital sex in the previous year did not differ significantly with the males (11.9 vs. 13.4?%, p value 0.752) and females (2.0 vs. 1.7?%, p value 0.127) from the general population. However, the labor migrants compared with the males from the general population were 1.51 times and the wives of labor migrants compared with the females from the general population were 2.37 times more likely to have been tested for HIV. Both the males from the general population and the labor migrants are equally engaged in unprotected extramarital sex. Therefore, it is recommended that the prevention programs, including access to condoms and HIV testing, should be scaled up targeting a broader range of individuals in the far-western region of Nepal.     

HIV Sexual Risk Behaviors and Multilevel Determinants Among Male Labor Migrants from Tajikistan

The purpose of this study was to investigate HIV risk behaviors and their multilevel determinants in male labor migrants from Tajikistan to Moscow. In Russia and Central Asia, where AIDS rates are amongst the world’s highest, conditions in both sending and receiving countries pose serious challenges to HIV prevention. A survey of Tajik married male seasonal labor migrants in Moscow was completed by 200 workers from 4 bazaars and 200 workers from 18 construction sites as part of a mixed method study. The quantitative results indicated that male labor migrants were at risk for HIV due to higher sexual behaviors including sexual relations with sex workers (92 %), multiple partnering in the past month (86 %), unprotected sex with sex workers (33 %), and reduced frequency of condom use while drinking alcohol (57 %). Multivariate tests indicated the multilevel factors that increased HIV sexual risks including: pre-migration factors (e.g. used sex workers in Tajikistan); migrant work and lifestyle factors (e.g. greater number of times visited Moscow); migrant sexual and relational factors (e.g. regular partner in Moscow); and migrant health and mental health factors (e.g. increased frequency of alcohol use). Qualitative findings from longitudinal ethnographic interviews and observations of a subset of 40 purposively sampled Tajik male migrants demonstrated how these multilevel pre-migration and migration factors account for HIV risk and protective behaviors in context. These findings underscore the seriousness of HIV risk for labor migrants and call both for multilevel approaches to prevention and for further study.     

Female Migrant Sex Workers in Moscow: Gender and Power Factors and HIV Risk

This study aimed to build formative knowledge regarding HIV risks in female migrant sex workers in Moscow, focusing on gender and power. This was a collaborative ethnographic study, informed by the theory of gender and power, in which researchers conducted minimally structured interviews with 24 female sex workers who were migrants to Moscow and who provided sexual services to male migrant laborers. Overall, the female migrant sex workers engaged in HIV risk behaviors and practiced inadequate HIV protection with their clients. These behaviors were shaped by gender and power factors in the realms of labor, behavior, and cathexis. In the labor realm, because some female migrants were unable to earn enough money to support their families, they were pushed or pulled into sex work providing service to male migrants. In the behavior realm, many female migrant sex workers were intimidated by their male clients, feared violence, and lacked access to women's health care and prevention. In the cathexis realm, many had a sense of shame, social isolation, emotional distress, and lacked basic HIV knowledge and prevention skills. To prevent HIV transmission requires addressing the gender and power factors that shape HIV/AIDS risks among female migrant sex workers through multilevel intervention strategies.     

HIV Vulnerability and Condom Use Among Migrant Women Factory Workers in Puebla,Mexico

International migration is associated with increased HIV vulnerability, but little is known about the vulnerability of internal migrants. This qualitative study explored perceptions of HIV and condom use among Mexican migrant female factory workers. Migration and male sexual infidelity contributed to increased HIV vulnerability and unprotected sex was ubiquitous. The dominant cultural discourse that dichotomizes “good” (monogamous) and “bad” (sexually stigmatized) women, and male partner's resistance, were barriers to condom use. Women's positive attitudes toward the dual protection (pregnancy and sexually transmitted infections) offered by condoms and sexual agency expressed by refusing unwanted sexual contact are resources for HIV prevention.

Male migrants' non-spousal sexual partnerships in the place of origin: an in-depth investigation in two rural settings of India

Male migrants in India are at disproportionately high risk for HIV, not only because of their sexual behaviours in destination areas but also due to their risk behaviours in their place of origin. While studies have documented male migrants' risky behaviours in the home setting, few have attempted to understand the underlying socio-cultural context in which they engage in such behaviours. This paper examines the patterns and context of male migrants' non-spousal sexual partnerships in two high-out-migration districts of India. Data, drawn from a cross-sectional behavioural mixed-methods study conducted in 2008, included a structured survey with 1272 migrants, followed by in-depth interviews with 33 male migrants. Results suggest that sexual activity was common in the place of origin: around 50% of migrants had sex with a non-spousal female partner and two-fifths had initiated sex in this setting. Migrants' non-spousal sexual behaviours in the home village were influenced by the prevailing socio-cultural context, including migrants' enhanced socio-economic status, attitudes to non-spousal sex and accessibility of sexual partners. Male migrants' non-spousal sexual partnerships in source areas are influenced by socio-cultural factors, which must be considered when designing HIV programmes in India and elsewhere.     

The role of housing in determining HIV risk among female sex workers in Andhra Pradesh, India: considering women's life contexts

Recent research on HIV prevention, regardless of the population, has increasingly recognized the relevance of contextual factors in determining HIV risk. Investigating such factors among female sex workers (FSW) is especially relevant in the South Indian state of Andhra Pradesh, where HIV rates are among the highest across Indian states and where HIV has largely affected FSW. Stable housing is a particular contextual challenge experienced by female sex workers in this region (as well as elsewhere); however, local studies have not examined the impact of this issue on HIV risk. In this paper, we examine residential instability, defined as a high frequency of reported evictions, among FSW and relation to experiences of violence (as a factor increasing risk for HIV) and sexual risk factors for HIV. Women were recruited through respondent-driven sampling for a survey on HIV risk. Using logistic regression models, we assessed: (1) residential instability and association with HIV sexual risk variables (including unprotected sex, reported STIs, and recent physical and sexual victimization) and (2) whether the association between residential instability and reported STI (as an indicator of HIV risk) was attenuated by individual risk behaviors and violence. In adjusted logistic regression models, FSW who reported residential instability were more likely to report: sexual violence, physical violence, accepting more money for unprotected sex, and a recent STI symptom. Violence associated with residential instability contributed to reported STIs; however, residential instability remained significantly associated with STIs beyond the influence of both violence and unprotected sex with clients. Findings highlight the interrelation among residential instability, violence, and HIV risk. Residential instability appears to be associated with women's HIV risk, above and beyond its association with individual risky sexual behaviors.     

HIV risks among women who are married to men who have sex with men in India: a qualitative investigation

In countries such as India, men who have same-sex partnerships may marry women due to cultural pressures regardless of their sexual desires and preferences. The wives of such men may be at risk for HIV but limited existing research addresses this issue. This qualitative study used in-depth interviews to investigate HIV-related risk among married men who have sex with men (n = 34) and women who were aware of their husband’s same-sex behaviour (n = 13) from six research sites in five states and a Union Territory in India: Delhi (Delhi), Visakhapatnam (Andhra Pradesh), Hyderabad (Telangana), Bengaluru (Karnataka), Chennai and Madurai (Tamil Nadu). Thematic analysis revealed that wives of men who have sex with men were at risk for HIV from their husbands’ sexual practices, which are often hidden to avoid the potential consequences of stigmatisation, as well as from gender-based inequities that make husbands the primary decision-makers about sex and condom use, even when wives are aware of their husband’s same-sex behaviour. Innovative interventions are needed to address HIV-related risk in couples where wives remain unaware of their husband’s same-sex behaviour, and for wives who are aware but remain within these marriages.     

Exploring HIV Knowledge,Risk and Protective Factors Among West African Forced Migrants in New York City

Because of ongoing political and social instability throughout the continent, many Africans have become forced migrants. Unlike immigrants who choose to migrate, forced migrants flee their countries in search of safety and often endure multiple traumatic events during their migration. They are often unprepared for new risks in their adopted country. There is a high incidence of newly-diagnosed HIV cases among West African immigrants in the New York City metropolitan area, but little research to date to understand why this might occur. In order to gain insight, the current pilot study explored HIV knowledge, risk and protective behaviors among 52 West African-born forced migrants in New York City. HIV risk behavior came primarily from unprotected heterosexual activities. While most participants were very knowledgeable about HIV transmission and risk factors, almost half reported that they had not used condoms during sexual activities in the past 6 months. Women were more knowledgeable about HIV transmission, yet reported significantly more STDs than men. Many participants did not know about HIV/AIDS treatments and could not identify HIV/AIDS services and resources within their immigrant communities. Factors influencing HIV risk and protective behaviors among this population are identified and discussed. Suggestions for future research and strategies to reduce risky behaviors while enhancing protective ones among forced West African migrants are highlighted.     

Risk behaviours for HIV infection among travelling Mexican migrants: The Mexico–US border as a contextual risk factor

The Mexico–US border region is a transit point in the trajectory of Mexican migrants travelling to and from the USA and a final destination for domestic migrants from other regions in Mexico. This region also represents a high-risk environment that may increase risk for HIV among migrants and the communities they connect. We conducted a cross-sectional, population-based survey, in Tijuana, Mexico, and compared Mexican migrants with a recent stay on the Mexico–US border region (Border, n?=?553) with migrants arriving at the border from Mexican sending communities (Northbound, n?=?1077). After controlling for demographics and migration history, border migrants were more likely to perceive their risk for HIV infection as high in this region and regard this area as a liberal place for sexual behaviours compared to Northbound migrants reporting on their perceptions of the sending communities (p?p?相似文献   

HIV infection in mobile populations: the case of Mexican migrants to the United States.

OBJECTIVE: Previous studies have indicated varying rates of HIV infection among labor migrants to the United States of America. Most of these studies have been conducted with convenience samples of farmworkers, thus presenting limited external validity. This study sought to estimate the prevalence of HIV infection and risk factors among Mexican migrants traveling through the border region of Tijuana, Baja California, Mexico, and San Diego, California, United States. This region handles 37% of the migrant flow between Mexico and the United States and represents the natural port of entry for Mexican migrants to California. METHODS: From April to December 2002 a probability survey was conducted at key migrant crossing points in Tijuana. Mexican migrants, including ones with a history of illegal migration to the United States, completed an interview on HIV risk factors (n = 1 429) and an oral HIV antibody test (n = 1,041). RESULTS: Despite reporting risk factors for HIV infection, none of the migrants tested positive for HIV. CONCLUSIONS: Our findings contrast with previous estimates of HIV among labor migrants in the United States that were based on nonprobability samples. Our findings also underline the need for early HIV prevention interventions targeting this population of Mexican migrants.     

Incarceration and High-Risk Sex Partnerships among Men in the United States

Incarceration is associated with multiple and concurrent partnerships, which are determinants of sexually transmitted infections (STI), including HIV. The associations between incarceration and high-risk sex partnerships may exist, in part, because incarceration disrupts stable sex partnerships, some of which are protective against high-risk sex partnerships. When investigating STI/HIV risk among those with incarceration histories, it is important to consider the potential role of drug use as a factor contributing to sexual risk behavior. First, incarceration’s influence on sexual risk taking may be further heightened by drug-related effects on sexual behavior. Second, drug users may have fewer economic and social resources to manage the disruption of incarceration than nonusers of drugs, leaving this group particularly vulnerable to the disruptive effects of incarceration on sexual risk behavior. Using the 2002 National Survey of Family Growth, we conducted multivariable analyses to estimate associations between incarceration in the past 12 months and engagement in multiple partnerships, concurrent partnerships, and unprotected sex in the past 12 months, stratified by status of illicit drug use (defined as use of cocaine, crack, or injection drugs in the past 12 months), among adult men in the US. Illicit drug users were much more likely than nonusers of illicit drugs to have had concurrent partnerships (16% and 6%), multiple partnerships (45% and 18%), and unprotected sex (32% and 19%). Analyses adjusting for age, race, educational attainment, poverty status, marital status, cohabitation status, and age at first sex indicated that incarceration was associated with concurrent partnerships among nonusers of illicit drugs (adjusted prevalence ratio (aPR) 1.55, 95% confidence interval (CI) 1.06–2.22) and illicit drug users (aPR 2.14, 95% CI 1.07–4.29). While incarceration was also associated with multiple partnerships and unprotected sex among nonusers of illicit drugs (multiple partnerships: aPR 1.66, 95% CI 1.43–1.93; unprotected sex: aPR 1.99, 95% CI 1.45–2.72), incarceration was not associated with these behaviors among illicit drug users (multiple partnerships: aPR 1.03, 95% CI 0.79–1.35; unprotected sex: aPR 0.73, 95% CI 0.41–1.31); among illicit drug users, multiple partnerships and unprotected sex were common irrespective of incarceration history. These findings support the need for correctional facility- and community-based STI/HIV prevention efforts including STI/HIV education, testing, and care for current and former prisoners with and without drug use histories. Men with both illicit drug use and incarceration histories may experience particular vulnerability to STI/HIV, as a result of having disproportionate levels of concurrent partnerships and high levels of unprotected sex. We hypothesize that incarceration works in tandem with drug use and other adverse social and economic factors to increase sexual risk behavior. To establish whether incarceration is causally associated with high-risk sex partnerships and acquisition of STI/HIV, a longitudinal study that accurately measures incarceration, STI/HIV, and illicit drug use should be conducted to disentangle the specific effects of each variable of interest on risk behavior and STI/HIV acquisition.     

Psychosocial Correlates of Unprotected Sex Without Disclosure of HIV-Positivity among African-American,Latino, and White Men Who Have Sex with Men and Women

African-American, Latino, and White men who have sex with men and women (MSMW) may be a bridge of HIV transmission from men to women. Very little research has directly compared culturally specific correlates of the likelihood of unprotected sex among MSMW. The present study examined psychosocial correlates of unprotected sex without disclosure of HIV status with male and female partners among 50 African American, 50 Latino, and 50 White HIV-positive MSMW recruited from AIDS service organizations in Los Angeles County. Multivariate logistic regressions were conducted to examine relationships of race/ethnicity and psychosocial variables (e.g., condom attitudes, self-efficacy for HIV disclosure, sexual identification) to unprotected sex without disclosure of HIV status, for male and female partners separately. For female partners, different effects emerged by race/ethnicity. Among African-Americans, less exclusively homosexual identification and low self-efficacy for disclosure of HIV status to female partners were associated with unprotected sex without disclosure; among Latinos, less exclusively homosexual identification and negative attitudes about condoms were significant. Participants who were more exclusively homosexually identified, who held less positive condom attitudes, and who had low self-efficacy for disclosure to female partners were more likely to have unprotected sex without disclosure of HIV status to male partners. Culturally tailored community-level interventions may help to raise awareness about HIV and bisexuality, and decrease HIV and sexual orientation stigma, thereby increasing African-American and Latino MSMW's comfort in communicating with their female partners about sexuality, HIV and condoms. Addressing norms for condom use and disclosure between male partners is recommended, especially for homosexually identified MSMW.

The Potential for Bridging of HIV Transmission in the Russian Federation: Sex Risk Behaviors and HIV Prevalence among Drug Users (DUs) and their Non-DU Sex Partners

The HIV epidemic that began in Russia in the mid-1990s has been concentrated mostly among drug users (DUs). Recent evidence of increasing HIV cases among non-DUs attributed to sexual behavior raises potential concern about a more generalized epidemic. The purpose of this analysis is to examine the potential for HIV transmission from DUs to their non-DU sex partners. Analyses are conducted using data collected during 2005–2008 in St. Petersburg, Russia. A total of 631 DUs were recruited into the sample with an HIV prevalence of 45%. A majority (84%) of DUs reported being sexually active in the past 6 months, and the DU status of their sex partners was reported as follows: 54% DU, 40% non-DU, and 6% unknown DU status. In 41% of partnerships with an HIV-negative or unknown status partner not known to be DU (potential bridging partnerships), the last reported intercourse was unprotected. Female DUs with potential bridging partnerships were more likely than male DUs to be younger and report homelessness and to have multiple or new sex partners. Many non-DU sex partners of DUs enrolled in the study reported new sex partners in the past 6 months (66%), unprotected intercourse at last sex (60%), and multiple sex partners in the past 6 months (48%). HIV prevalence in this group was 15% (eight out of 53). The high prevalence of HIV among DUs, their sexual contact with non-DUs, and the high-risk sexual behaviors of this potential bridging population together indicate the real potential for an increasingly generalized epidemic. The degree to which there will be further transmission from non-DU sex partners of DUs who exhibit high levels of sex risk behaviors to other non-DU sex partners deserves further study.

Reaching hard-to-reach migrants by letters: an HIV/AIDS awareness programme in Nepal

We assessed the impact of an HIV/AIDS programme for Nepalese migrants to India that involved writing letters. The programme created opportunities for sending HIV/AIDS-related messages to the migrants in India, and encouraging them practicing safer sex. Initially, they received the messages only from the programme, but later from their colleagues, spouses or other family members. They discussed the messages in groups, disseminated them, and sought more knowledge in their destinations. These findings indicated that using letters could be an effective way to reach inaccessible migrants at their destinations, and help them to improve their HIV/AIDS-related knowledge, and safer sex practices.     

Gender, migration, risky sex, and HIV infection in China

Gender differences in sexual behavior as a consequence of migration have been ignored in both the migration and the HIV literature in China. This study examines differences among temporary migrants in terms of sexual behavior and factors that make female migrants more vulnerable to the risk of acquiring HIV infection. Results suggest that the interplay of migration and gender renders female temporary migrants particularly vulnerable to engaging in casual and commercial sex. Although male temporary migrants do not differ from male nonmigrants in prevalence of casual and commercial sex, the prevalence rates of casual and commercial sex for female temporary migrants are found to be 14 and 80 times those for female nonmigrants, respectively. Female temporary migrants' higher unemployment rate and concentration in the service and entertainment sectors are keys to understanding differences in the prevalence of casual and commercial sex among temporary migrants according to sex. Policy measures to promote female temporary migrants' equal access to employment are urgently needed to improve their economic well-being and to reduce their risky sexual behavior.
