Background: Despite multiple years of government HIV educational efforts, the growing trend of new cases among women in Indonesia runs parallel with their seemingly overall lack of comprehensive knowledge about HIV. A major prevention challenge for the Indonesian government lies in delivering HIV prevention education across the world's largest archipelago. This study investigates comprehensive HIV knowledge among reproductive-age women in Southwest Sumba, Indonesia, and the sources through which they report having learned about HIV along with potential mediators of the relationship between socioeconomic status (SES) and HIV knowledge., Methods: This cross-sectional study using convenience sampling recruited 159 married women ages 15-49 years old living in 4 selected church parishes in Southwest Sumba on March 12-20, 2023. The HIV Knowledge Questionnaire-18 and items from the 2017 Indonesian Demographic and Health Survey (24 total) measured the women's comprehensive knowledge about HIV. Additional items asked about sources through which the women had received information about HIV. One-way ANOVA examined differences in the level of HIV knowledge obtained through one or more information sources (healthcare providers, media, schools, and social network members). Mediation analysis investigated potential mediators of the relationship between SES and HIV knowledge., Results: Comprehensive HIV knowledge scores ranged from 0 to 21 (mean = 10.6). About 65% of the 159 women could only correctly answer 50% or less of the questions. Most incorrect answers pertained either to Mother-to-Child HIV Transmission (MTCT) or misconceptions about the virus. One-way ANOVA revealed that the mean of HIV knowledge increased as the number of informational sources increased (p < .001). Structural Equation Modelling found that social network members, healthcare providers, and the media all had significant direct effects on HIV knowledge. In addition, an indirect positive relationship between SES and comprehensive HIV knowledge was mediated by information obtained through the media and marginally through healthcare providers., Conclusions: The study's results suggest that more extensive in-depth HIV education is greatly needed to help prevent transmission among women living in small and outlying islands in Indonesia. Wider promotion of HIV information through the media and more intensively through local healthcare providers appears a promising and likely effective means to reach these women., Competing Interests: Declarations. Ethics approval and consent to participate: This study was performed in line with the principles of the Declaration of Helsinki. Approval was granted by The Institutional Review Board (IRB) University of Illinois at Chicago (STUDY2022-1016, approved on November 10, 2022), Atma Jaya Catholic University of Indonesia (approved on January 18, 2023), The Southwest Sumba Agency of National Unity, Politics, and Community Protection, Southwest Sumba Health District Office, and selected parishes. Informed consent was obtained from all participants included in the study. Our sample consists solely of married or previously married women between 15–49 years of age. As Indonesian Civil Code article 330 specifies that a person is considered an adult upon reaching age 21 or marrying, all participants were defined by law as legally able to give informed consent; none needed parental consent or childhood assent to do so.

Background: In a cluster-randomized controlled trial, the "Migrants' Approached Self-Learning Intervention in HIV/AIDS for Tajiks" (MASLIHAT) reduced intervention participants' sexual risk behaviour including any condomless sex, condomless sex with female sex workers, and multiple sexual partners. This analysis investigates if observed changes in sexual risk behaviors translated into fewer reported STIs among participants over 12-month follow-up., Methods: The MASLIHAT intervention was tested in a cluster-randomized controlled trial with sites assigned to either the MASLIHAT intervention or comparison health education training (TANSIHAT). Participants and network members (n=420) were interviewed at baseline and 3-month intervals for one year to assess HIV/STI sex and drug risk behaviour. We conducted mixed effects robust Poisson regression analyses to test for differences between conditions in self-reported STIs during 12 months of follow-up, and to test the contribution of sexual risk behaviours to STI acquisition. We then tested the mediating effects of sexual behaviours during the first six months following the intervention on STIs reported at the 9 and 12-month follow-up interviews., Results: Participants in the MASLIHAT condition were significantly less likely to report an STI during follow-up (IRR=0.27, 95% CI 0.13-0.58). Condomless sex with a non-main (casual or commercial) partner was significantly associated with STI acquisition (IRR=2.30, 95% CI 1.26-4.21). Adjusting for condomless sex with a non-main partner, the effect of MASLIHAT intervention participation was reduced (IRR=0.36, 95% CI 0.16-0.80), signalling possible mediation. Causal mediation analysis indicated that the intervention's effect on reported STI was partially mediated by reductions among MASLIHAT participants in condomless sex with a non-main partner., Conclusions: The MASLIHAT peer-education intervention reduced reported STIs among Tajik labour migrants partly through reduced condomless sex with casual and commercial partners., Clinical Trial Registration: ClinicalTrials.gov, 2021-04-16, NCT04853394.

Introduction: The "Migrants' Approached Self-Learning Intervention in HIV/AIDS for Tajiks" (MASLIHAT) recruits and trains Tajik labour migrants who inject drugs as peer educators (PEs) in delivering HIV prevention information and encouragement to adopt risk-reduction norms and practices within their diaspora social networks while reducing their own HIV risk., Methods: The MASLIHAT intervention was tested in Moscow in a cluster-randomized controlled trial with 12 recruitment sites assigned to either the MASLIHAT intervention or an equal-time peer-educator training focused on other health conditions (TANSIHAT). From October 2021 to April 2022, 140 male Tajik migrants who inject drugs were recruited as PEs to attend the 5-session MASLIHAT training or the TANSIHAT non-HIV comparison condition. Each participant in both groups recruited two network members (NMs) who inject drugs with the intent to share with them the information and positive strategies for change they had learned (n = 280). All PEs and NMs (n = 420) participated in baseline and follow-up interviews at 3-month intervals for 1 year. All received HIV counselling and testing. Modified mixed effects Poisson regressions tested for group differences in injection practices, sexual risk behaviours and heavy alcohol use over time., Results: At baseline, across both groups, 75% of participants reported receptive syringe sharing (RSS), 42% reported condomless sex and 20% reported binge drinking at least once a month. In contrast to TANSIHAT where HIV risk behaviours remained the same, significant intervention effects that were sustained over the 12 months were observed for receptive syringe and ancillary equipment sharing among both MASLIHAT PEs and NMs (p < 0.0001). Significant declines in the prevalence of sexual risk behaviours were also associated with the MASLIHAT intervention (p < 0.01), but not the comparison condition. Binge alcohol use was not affected in either condition; the MASLIHAT intervention had a transitory effect on drinking frequency that dissipated after 9 months., Conclusions: The MASLIHAT peer-education intervention proved highly effective in reducing HIV-related injection risk behaviour, and moderately effective in reducing sexual risk behaviour among both PEs and NMs. Network-based peer education is an important tool for HIV prevention among people who inject drugs, especially in environments that are not amenable to community-based harm reduction., (© 2024 The Author(s).

Introduction: Assisted partner notification (APN) safely and effectively increases partner awareness of HIV exposure, testing and case identification in community settings. Nonetheless, it has not been specifically developed or evaluated for use in prison settings where people with HIV often are diagnosed and may have difficulty contacting or otherwise notifying partners. We developed Impart, a prison-based APN model, and evaluated its efficacy in Indonesia to increase partner notification and HIV testing., Methods: From January 2020 to January 2021, 55 incarcerated men with HIV were recruited as index participants from six jail and prison facilities in Jakarta in a two-group randomized trial comparing the outcomes of self-tell notification (treatment as usual) versus Impart APN in increasing partner notification and HIV testing. Participants voluntarily provided names and contact information for sex and drug-injection partners in the community with whom they had shared possible HIV exposure during the year prior to incarceration. Participants randomized to the self-tell only condition were coached in how to notify their partners by phone, mail or during an in-person visit within 6 weeks. Participants randomized to Impart APN could choose between self-tell notification or anonymous APN by a two-person team consisting of a nurse and outreach worker. We compared the proportion of partners in each group who were notified of exposure by the end of 6 weeks, subsequently tested and HIV diagnosed., Results: Index participants (n = 55) selected 117 partners for notification. Compared to self-tell notification, Impart APN resulted in nearly a six-fold increase in the odds of a named partner being notified of HIV exposure. Nearly two thirds of the partners notified through Impart APN (15/24) completed HIV testing within 6 weeks post notification compared to none of those whom participants had self-notified. One-third of the partners (5/15) who completed HIV testing post notification were diagnosed as HIV positive for the first time., Conclusions: Voluntary APN can be successfully implemented with a prison population and within a prison setting despite the many barriers to HIV notification that incarceration presents. Our findings suggest that the Impart model holds considerable promise to increase partner notification, HIV testing and diagnosis among sex and drug-injecting partners of HIV-positive incarcerated men., (© 2023 The Authors.

The human immunodeficiency virus (HIV) epidemic in Eastern Europe and Central Asia continues to grow with most infections occurring in high-risk groups including people who inject drugs and their sexual partners. Labor migrants from this region who inject drugs while in Russia are at especially high HIV risk. Male Tajik migrant workers who inject drugs in Moscow (N = 420) were interviewed prior to a randomized trial of the Migrants' Approached Self-Learning Intervention in HIV/AIDS (MASLIHAT) peer-education HIV-prevention intervention. Participants were interviewed about their sex and drug use behavior and tested for HIV and hepatitis C (HCV) prior to the intervention. Only 17% had ever been tested for HIV. Over half of the men reported injecting with a previously used syringe in the past month, and substantial proportions reported risky sexual behavior. Prevalence rates of HIV (6.8%) and HCV (2.9%) were elevated, although lower than expected when compared to estimates of prevalence among people who inject drugs at the national level in Tajikistan. Risk behavior in diaspora varied across the men's regional area of origin in Tajikistan and occupation in Moscow, with HIV prevalence rates highest among those working at the bazaars. Evidence-based prevention approaches and messaging that specifically address the drug- and sex-related risk behavior of migrants with varying backgrounds are needed.

Background . The HIV epidemic in Eastern Europe and Central Asia continues to grow with most infections occurring in high-risk groups including people who inject drugs and their sexual partners. Labor migrants from this region who inject drugs while in Russia are at especially high HIV risk. Methods . We recruited 420 male Tajik migrant workers who inject drugs in Moscow for a peer-education HIV prevention intervention trial. Participants were interviewed about their sex and drug use behavior and tested for HIV and hepatitis C prior to the intervention. Results . Over half of the men reported injecting with a previously used syringe in the past month. Many men reported condomless sex (42%), multiple sex partners (30%), and sex with sex workers (42%). Only 17% had ever been tested for HIV. Despite substantial risk behavior, prevalence rates of HIV (6.8%) and HCV (2.9%) although elevated were lower than expected when compared to estimates of prevalence among PWID at the national level in Tajikistan. Risk behavior in diaspora varied across the men’s regional area of origin in Tajikistan and occupation in Moscow with HIV prevalence rates highest among those working at the bazaars. Conclusion . Tajik male migrants who inject drugs in Moscow are at heightened risk for HIV and hepatitis C. Evidence-based prevention approaches and messaging that specifically address the drug- and sex-related risk behavior of migrants from different parts of Tajikistan, employment sectors within the destination city, and socio-demographic background are needed.

Background: Assisted partner notification (APN) is recommended as a public health strategy to increase HIV testing in people exposed to HIV. Yet its adoption in many countries remains at an early stage. This qualitative study sought the opinions of HIV health service providers regarding the appropriateness and feasibility of implementing APN in Indonesia where such services are on the cusp of adoption., Methods: Four focus group discussions totaling 40 health service providers were held in Jakarta, Indonesia to consider APN as an innovative concept and to share their reactions regarding its potential implementation in Indonesia. Voice-recorded discussions were conducted in Bahasa, transcribed verbatim, and analyzed., Results: Participants recognized APN's potential in contacting and informing the partners of HIV-positive clients of possible viral exposure. They also perceived APN's value as a client-driven service permitting clients to select which of three partner notification methods would work best for them across differing partner relationships and settings. Nonetheless, participants also identified personal and health system challenges that could impede successful APN adoption including medical and human resource limitations, the need for specialized APN training, ethical and equity considerations, and lack of sufficient clarity concerning laws and government policies regulating 3 rd party disclosures. They also pointed to the job-overload, stress, personal discomfort, and the ethical uncertainty that providers might experience in delivering APN., Conclusion: Overall, providers of HIV services embraced the concept of APN but forecast practical difficulties in key service areas where investments in resources and system change appeared necessary to ensure effective and equitable implementation., (© 2023.

Intimate partner violence (IPV) in China is a largely understudied, major health risk among women living with HIV. Using structured face-to-face interviews, this research examined partner and couple relationship characteristics associated with physical and sexual IPV among 219 HIV-positive women living with a male partner in Ruili, China. Twenty-nine women (13%) reported past-year occurrences of physical IPV, and 24 (11%) reported sexual IPV. Physical IPV was more common when the woman's partner was of Jingpo ethnicity, drank weekly, or learned of her HIV status indirectly from a third person. Reduced risk of physical IPV was associated with a woman's perceived confidant support that was available through either her partner or a minimum of 2 non-partner confidants. Sexual IPV was more often reported among women with a partner who drank frequently or was concurrently HIV-positive, or in situations where the woman was employed and the partner was not. Sexual IPV was less likely with a partner of Dai ethnicity than Han, the major ethnicity in China. Identifying determinants of IPV vulnerability among women living with HIV may help future interventions to achieve greater impact in similar settings., (© 2022.

We developed and pilot-tested the Migrants' Approached Self-Learning Intervention in HIV/AIDS for Tajiks (MASLIHAT). We recruited 30 Tajik labor migrants who inject drugs in Moscow as peer educators (PEs) to attend the 5-session intervention, then share what they learned with their peers. Each PE recruited two drug-injecting network members for interviewing about their drug and sexual behavior at baseline, 6 weeks, 3 months, and 6 months post-intervention. GEE and mixed effects regression tested time and participant type effects on each outcome. HIV knowledge and risk perception increased among both PEs and network peers, while use of shared syringes, condomless sex, sex with a sex worker, and alcohol use decreased significantly for both groups at 6 weeks and 3 months with a sustained effect through 6 months. The MASLIHAT intervention proved successful in disseminating HIV prevention information and reducing HIV risk behavior over 6 months among both PEs and network members., (© 2021.

Objectives: To understand key factors influencing Chilean health care providers' perceived comfort performing oral rapid HIV testing., Design: One hundred and fifty health care providers completed a self-administered questionnaire that included a five-item scale measuring self-perceived comfort in conducting HIV pretest counseling, oral rapid testing, finger-prick testing, and delivering test results., Results: Most participants (60%) envisioned good overall comfort performing oral rapid HIV testing (mean score of 16.21; range 0-20), including doing at least four of the five steps. They perceived least comfort delivering HIV-positive test results during posttest counseling. HIV stigmatizing attitudes reduced self-perceived comfort., Conclusions: Providing training to counter HIV stigmatization while increasing comfort in performing oral rapid testing would help facilitate its successful implementation.

We examined virological non-suppression (VLN) among youth ages 13-24 years receiving HIV treatment in public health facilities in six southern Malawi districts. We also tested three ART adherence measures to determine how well each identified VLN: pill counts, a Likert scale item, and a visual analogue scale. VLN was defined as HIV RNA > 1000 copies/ml. Of the 209 youth, 81 (39%) were virally non-suppressed. Male gender and stigma were independently associated with VLN; social support and self-efficacy were independently protective. Pill count had the highest positive predictive value (66.3%). Using a pill count cut-off of < 80% nonadherence, 36 (17%) of the youth were non-adherent. Of the adherent, 120 (69%) were viral suppressed. Results indicate the need to address HIV-related stigma and to bolster social support and selfefficacy in order to enhance viral suppression. In the absence of viral load testing, pill count appears the most accurate means to assess VLN.

Partner services provide a safe and humane way for people living with HIV (PLWH) to alert their sex and/or drug-injecting partners to the possibility of HIV exposure and the need for HIV testing, yet little is known about the ethical challenges of delivering partner services in prisons. In this article, we consider 7 key ethical and methodological questions that should be considered when developing, testing, or implementing partner services in prison settings. These questions relate to the ethics of: (1) mandatory HIV testing, (2) health illiteracy, (3) level of prison staff involvement, (4) protecting confidentiality, (5) minimizing harm, (6) achieving equivalency with community standards of care, and (7) providing HIV prevention and treatment services to index patient and their partners. By assisting PLWH in prison to inform partners with whom they may have shared HIV exposure either before or during incarceration, partner services can help to identify cases of undiagnosed HIV infection for testing and linkage to medical care. The acceptability and effectiveness of a future partner services model for PLWH in prison depends critically on answering these 7 questions to assure the highest ethical standards of research and practice.

Using an ecological model, we describe substance use and sexual risk behaviors of young male laborers at a roadside market in Malawi. Data included observations and interviews with 18 key market leaders and 15 laborers (ages 18-25 years). Alcohol, marijuana, and commercial sex workers (CSWs) were widely available. We identified three patterns of substance use: 6 young men currently used, 6 formerly used, and 3 never used. Substance use was linked to risky sex, including sex with CSWs. The market supported risky behaviors through availability of resources; supportive norms, including beliefs that substance use enhanced strength; and lack of restraints. Community-level poverty, cultural support for alcohol, interpersonal family/peer influences, early substance use, and school dropout also contributed to risky behaviors. Parental guidance was protective but not often reported. Local programs addressing substance use and risky sex simultaneously and better national substance use policies and mental health services are needed., (Copyright © 2015 Association of Nurses in AIDS Care.

Objective: This study identified the personal characteristics that affect Chilean health care providers' readiness to adopt HIV Oral Rapid Testing (ORT) in Chile as a new clinical evidence-based practice (EBP)., Methods: Using a cross-sectional research design, the study sampled 150 nurses, midwives, and physicians employed at four clinics within the Pontifícia Universidad Católica de Chile Health Network in Santiago. Participants completed a self-administered survey asking about their demographic background, EBP attitudes and experience, personal beliefs related to HIV, the importance of HIV testing, and perceived self-comfort in performing a rapid HIV test., Results: Of the participants, 90% believed that incorporating ORT would make a positive difference in their practice and said that they would be willing to adopt the technology for that reason. Nonetheless, the providers reported a mean "readiness to implement ORT" score of 15.1 out of a possible value of 20, suggesting only moderate self-perceived readiness to adopt the EBP. Education, beliefs about evidence-based practice, perceived comfort in performing ORT, and perceived importance of HIV testing explained 43.6% of the variance in readiness to adopt ORT., Conclusion: The findings of this first ORT pre-implementation study in Chile can help guide policy makers and HIV stakeholders to prepare for and increase primary health care providers' readiness to successfully adopt this evidence-based technology. Successful adoption of ORT could increase Chile's capacity to reach HIV-vulnerable Chileans for testing and referral to care if infected, thus helping the country to reduce further transmission of the virus and its medical complications.

Objectives. The HIV epidemic has drastically increased among older adults in China, yet little research has examined the psychological impacts among older and younger people living with HIV/AIDS (PLWHAs). This study examined and compared self-efficacy, depression, well-being, and quality of life among older and younger PLWHAs in China. Method. A two-stage sampling procedure was used to recruit a final sample of 148 participants. Older adults were defined as age 50 and older. Result. Compared to younger PLWHAs aged 18-49 years old, older PLWHAs reported lower levels of well-being (7.6 versus 11.4), higher levels of depression (18.6 versus 15.8), and poorer quality of life. Self-efficacy was similar among older (23.9) and younger (24.6) PLWHAs. A higher level of depression among older PLWHAs was associated with much lower levels of subjective well-being and quality of life (physical health and psychological health). Conclusion. The findings suggest that older PLWHAs face psychological problems and mental health challenges beyond those experienced by younger PLWHAs. Intervention programs dedicated to improving mental health and quality of life are greatly needed for HIV infected older adults.

Background: This study examines the influence of the double jeopardy of being both a migrant and an injection drug user on the social marginalization of male Tajik labor-migrants working in Moscow and the influence of this dual-marginalization on HIV risk., Methods: Three focus group discussions of 8 participants each were conducted in Moscow with a total of 24 Tajik male migrants who regularly inject drugs (IDUs)., Results: Results suggest that male Tajik IDUs are at double jeopardy for social marginalization from both Russian society and their own Tajik migrant community. In the absence of adequate knowledge about HIV risk through needle-borne infection, such dual social rejection can help to push Tajik migrant IDUs toward forging close social alliances with their drug-using peers based on a sense of community through sharing drugs and injection equipment. Sexual contact with Russian female sex workers, many of whom use drugs, further contributes to HIV vulnerability and forms a potential bridge for the cross-over of the virus between both populations. With little to no access to formal health services, family and friends living in Moscow can form a sole source of social support at a personal level that can over-ride general community censure but which can lessen or disappear as drug dependency increases., Conclusion: Both drug and health services are sorely needed for this highly vulnerable population., (Copyright © 2013 Elsevier Ireland Ltd.

This paper examines the structural influence of sex work venues on condom use among female sex workers in the Senggigi area of Lombok, Indonesia. A cross-sectional design employing ethnographic observation, structured interviews and hierarchical linear modelling was used to examine condom use among female sex workers who solicited clients at three types of sex work venues: (1) freelance locations, (2) brothels and (3) entertainment places (karaoke bars and massage parlours). The sample consisted of 115 women 'nested' within 16 sex work venues drawn from the three venue types. Rate (39%) of condom use varied across sex work venues. Perceived management style, HIV/AIDS-related policies and risk-reduction services differed by venue, but this variation did not explain differences in condom use. At the individual level, higher condom use was associated with female sex workers having ever been married. At the client level, condoms were more likely to be used with foreign rather than domestic/local Indonesian clients. Low rates of condom use among Indonesian female sex workers during commercial sex suggests the need for increased HIV-prevention efforts that acknowledge sex worker characteristics and relationships with clients that place them at risk. Future research into the effects of social context on HIV risk should also be considered.

Border areas are important locations for understanding HIV transmission. This study examines individual and network correlates of border crossing and equipment sharing among methadone maintenance clients in Ruili City, a Chinese city on the Myanmar border. Data are from 298 clients enrolled in the Ruili Methadone Treatment Center. Clients were interviewed about drug use, HIV/AIDS knowledge, treatment motivation, and their social networks. Multinomial and logistic regression analysis were performed. Thirty percent of clients reported injecting in Myanmar. Compared to drug networks that usually inject in China, networks that inject equally in both places (border crossing) are more likely to share equipment. The association between HIV positive status and border-crossing was marginally significant and robust. Results indicate some added degree of risk among clients and drug networks who border-cross to use drugs. More research is needed to understand this phenomenon.

The number of people ages 50 or older living with HIV in the United States is increasing. Yet, few older adults see themselves at risk of infection. This study examines the heuristic reasoning that low income, minority adults, ages 50 or older use in calculating the likelihood of infection. The data are drawn from face-to-face interviews with a sample of 134 African American and Latino residents, ages 50 to 86, living in low-income housing in Chicago, Illinois, and Hartford, Connecticut. Results show that nearly half of the study's participants thought themselves to be at some level of risk for HIV. In self-assessing their risk, they relied on seven heuristic categories: self-imperilment, social imperilment, fate, incidental contact, situational safety, medical iatrogenesis, and self-protection. These findings extend our understanding of how individuals make sense of their likelihood of experiencing a major health threat and provide insight into more effective HIV prevention programming for older adults., (Copyright © 2011 Association of Nurses in AIDS Care.

Background: Female sex workers' (FSWs') use of alcohol, a known disinhibitor to risk behaviour, has been largely understudied. Knowledge of how various sex work venues influence FSW's alcohol consumption before engaging in commercial sex is even rarer. Our analysis identifies those factors across three types of sex-work venues that predict alcohol use among FSWs prior to paid sexual intercourse with clients. Our data were collected through structured interviews with FSWs engaging in commercial sex in Senggigi Beach, Lombok Island in the eastern Indonesian province of West Nusa Tenggara., Methods: Employing a cross-sectional and multilevel design, three categories of venues where FSWs meet clients in Senggigi were sampled: (1) discotheques and bars (freelance), (2) brothels, and (3) recreational enterprises such as karaoke establishments and massage parlors. The sample consisted of 115 women "nested" within 16 sex work venues. The FSWs reported on 326 clients interactions., Results: Results show that FSWs consumed alcohol before commercial sex with 157 (48%) of the 326 clients interactions. Alcohol use varied by differences in HIV policies and services offered at the sex work venue, the FSW's educational level and age, and client characteristics., Conclusion: Alcohol use is common prior to sexual intercourse among FSWs and their clients in Senggigi, and the venue where FSWs meet their clients influences the women's alcohol use. Freelancers were likelier to use alcohol than those who work at brothels and recreational enterprises. Given the recognized links between alcohol use prior to sex and high risk behaviour, HIV prevention programmes that discourage alcohol use should be introduced to both women who engage in commercial sex and also sex-work venue managers, owners, and clients., (Copyright © 2010 Elsevier B.V.

After nearly three decades of being virtually drug free, use of heroin and other illicit drugs has re-emerged in China as a major public health problem. One result is that drug abuse, particularly heroin injection, has come to play a predominant role in fueling China's AIDS epidemic. The first outbreak of HIV among China's IDUs was reported in the border area of Yunnan province between China and Myanmar where drug trafficking is heavy. Since then drug-related HIV has spread to all 31 provinces, autonomous regions and municipalities. This paper provides an overview to HIV/AIDS transmission through injection drug use in China. It begins with a brief history of the illicit drug trade in China, followed by a discussion of the emergence of drug related AIDS, and a profile of drug users and their sexual partners who have contracted the virus or who are vulnerable to infection. It ends by summarizing three national strategies being used by China to address both drug use and AIDS as major health threats.

Despite the rising number of cases of HIV in adults over age 50, older persons rarely are considered to be at risk for HIV/AIDS, and even though they may be involved in risky behavior, such as unprotected penetrative sex, they may not consider themselves vulnerable to becoming infected. Informed awareness of risk is essential to making positive decisions about adopting preventive measures. We examined demographic, sociobehavioral, and contextual factors that predict urban, low-income older adults' perception of HIV/AIDS risk. Logistic regression results from 398 residents aged 50-93 living in six buildings in two American cities found that males, younger participants (aged 50-61), those living in higher risk buildings, and those who worried more about contracting HIV/AIDS were more likely to perceive themselves to be at HIV/AIDS risk. Findings accounted for 32% of the variance and the prediction success rate was 72%. Results point to the importance of considering sociodemographic characteristics and environmental (contextual) factors as they influence heuristic decision making in understanding HIV/AIDS risk perception among low-income urban older adults and when designing HIV/AIDS education and intervention strategies targeting this population.

Community-based research brings together researchers and community members as partners to conduct research of mutual concern. This article describes the components necessary to implement a successful research partnership, taking as an example a study of human immunodeficiency virus (HIV) risk among residents of senior housing sites in two North American cities. The article describes important aspects of building and sustaining partnerships, the methods implemented to conduct research on sensitive topics, share resources, disseminate results and collaborate on programs and interventions to benefit the health and well-being of older adults.

Studies of HIV/AIDS in people older than age 50 typically must address a series of distinct, age-related methodological concerns if they are to develop and implement age-sensitive research designs and measures. In this article, the authors identify and discuss seven methodological challenges that researchers confront when planning and conducting studies of how HIV/AIDS affects older adults. These challenges involve the following: defining who qualifies as an older adult in studies of HIV/AIDS and aging; determining which subset of older adults to study; selecting an appropriate level of analysis; measuring age and aging as research constructs; confronting the practical problems of studying people whose ages are nearing the end of the human life course; resolving the ethical dilemmas of HIV/AIDS research that targets older adults; and successfully going from research to practice in disseminating study findings.

Drawing on both domestic and global international perspectives, this special issue is devoted to articles that confront the challenges of understanding, preventing, and intervening, with HIV/AIDS as an epidemic that carries increasingly serious consequences for a growing number of adults who are 50 years of age or older. This issue builds on papers first presented at an HIV/AIDS and aging conference sponsored in the fall of 2000 by the National Institute on Aging of the National Institutes of Health. The editors have selected articles that focus dually on what is currently known and what needs to be known to successfully address the needs of persons 50 years of age or older who are vulnerable to the virus's effects. This special issue is organized around a series of subsections representing key issues and research findings related to HIV/AIDS and aging issues, including the epidemiology of HIV/AIDS and aging, HIV/AIDS risk and risk behavior, settings and situations as social contexts of risk, clinical challenges with older populations, living with and managing HIV/AIDS, interventions and research methods, new frontiers and challenges, and strategies for action. Some articles are data driven, whereas others are reflective pieces that recount personal experiences in living with the virus or point to new directions for research and practice. In this introduction, the editors highlight findings and approaches from each article and further add to our knowledge by setting these articles within the context of major themes relevant to the study of HIV/AIDS in an aging population.

Aims: As conceptualized by Robert Park in 1928, the 'marginal man' occupies simultaneously an intermediate point between two distinct cultures that embody some level of contradictory normative expectations, behaviors and beliefs. This paper explores the influence of ageing and social change on the creation of marginality among injection drug users over age 50 who have been chronic heroin users since their youth., Design: Our data are drawn from in-depth interviews with 40 (28 male and 12 female) not-in-drug-treatment, active injecting drug users between the ages of 18 and 68., Setting: Our sample was recruited using street outreach as part of a larger, community-based study conducted from a converted storefront in a high crime, economically depressed neighborhood on the west side of Chicago., Findings: As they aged, and under the pressures of social change, the older users whom we studied moved from center positioning in the illicit drug culture of their youth to the margins of a differing drug culture of today where they participate largely unseen by others. Nostalgic for the 'Old School' mores of the past, and unable to transcend or assimilate fully into the cultural practices and norms of the 'New', they respond to their predicament by embracing 'poise' in the face of loneliness, stress and fear of victimization., Conclusions: Our respondents' experiences draw attention to the need to refine the field's theoretical and practical understandings of what it means to be marginal and its consequences for older drug users and people in general. The results also point to what happens when society changes but some of its members do not.

This study examines the influence of individual, contextual (building location and characteristics), and social network characteristics on HIV prevalence and risk behavior among people older than 50 years of age living in low-income senior housing in two cities, Hartford, Connecticut and Chicago, Illinois. The authors' study focuses on older residents of six buildings located in impoverished neighborhoods with high rates of HIV transmission through injection drug use and unprotected sexual activity, including the exchange of sex for drugs and money. The article is organized into three sections. First, the authors explore the HIV prevalence, distribution, and risk behaviors that may contribute to new infections among the buildings' older residents in general. These practices include unprotected sexual intercourse, sex with commercial sex workers, casual or multiple partners, regular use of alcohol and/or illicit drugs, and other high-risk activities that expose older residents to HIV, sexually transmitted diseases, and other negative health consequences. Next, the authors examine the relationship between building and neighborhood characteristics, the internal social organization of buildings, and the risk behaviors of individual residents by building residency. Finally, the authors use a social network analysis to identify possible entry points and transmission routes for HIV infection through drug and sexual exchanges between and among building residents and visitors. This approach also reveals variations in building structures that may facilitate the diffusion of HIV prevention efforts.

The linking of the Internet with health and medicine involves all levels of society, including individuals, health care providers, professional organizations, communities, and local and federal governments. A growing body of evidence suggests that despite the benefits of the Internet, this means of communication also figures into the creation of new forms of health risk for some users. This paper examines the effects of the Internet on the promotion of both health and illness. The discussion focuses on those factors of online communication that produce positive health outcomes and also the potential for health risk. Implications for health providers and for better serving patients are analyzed together with recommendations for improving services for those who go online to access health information.

The relationship between injection drug use and HIV was established early in the HIV epidemic, and injection drug use has continued to be an important risk factor for HIV throughout the world. This panel included 4 papers related to HIV prevention among drug users, focusing on effective prevention strategies, the importance of organizing the AIDS-affected community, the impact of knowledge of serostatus on risk behaviors, and developing interventions for drug-using homosexual and bisexual men. These papers, addressing various aspects of the epidemic and methods to enhance prevention efforts, all indicate that although extensive knowledge regarding how to reduce HIV risks among drug users has accumulated, many areas for further research and intervention development remain.
