A Plausible Causal Model of HAART-Efficacy Beliefs, HIV/AIDS Complacency, and HIV-Acquisition Risk Behavior Among Young Men Who Have Sex with Men

Despite considerable research, the causal relationship remains unclear between HIV/AIDS complacency, measured as reduced HIV/AIDS concern because of highly active antiretroviral therapy (HAART), and HIV risk behavior. Understanding the directionality and underpinnings of this relationship is critical for programs that target HIV/AIDS complacency as a means to reduce HIV incidence among men who have sex with men (MSM). This report uses structural equation modeling to evaluate a theory-based, HIV/AIDS complacency model on 1,593 MSM who participated in a venue-based, cross-sectional survey in six U.S. cities, 1998?C2000. Demonstrating adequate fit and stability across geographic samples, the model explained 15.0% of the variance in HIV-acquisition behavior among young MSM. Analyses that evaluated alternative models and models stratified by perceived risk for HIV infection suggest that HIV/AIDS complacency increases acquisition behavior by mediating the effects of two underlying HAART-efficacy beliefs. New research is needed to assess model effects on current acquisition risk behavior, and thus help inform prevention programs designed to reduce HIV/AIDS complacency and HIV incidence among young MSM.     

“家庭式同伴教育”干预模式对男男性接触者行为干预效果研究

目的探索建立针对男男同性恋（MSM）人群预防艾滋病高危行为的干预模式。方法采用“家庭式同伴教育”的方式,针对300名MSM进行预防艾滋病健康教育及高危行为干预,通过干预前后艾滋病知识知晓率、性取向及性行为的改变,评估该干预模式的效果。结果干预前后,300名MSM对艾滋病知识知晓率,同性间安全套使用率情况明显改善。结论“家庭式同伴教育”模式能够有效地提高MSM人群艾滋病知识水平并相应改变其高危行为,同时应该将坚持使用安全套作为MSM人群防控工作的重点。     

High Rates of Late HIV Diagnosis Among People Who Inject Drugs Compared to Men Who Have Sex with Men and Heterosexual Men and Women in Australia

We aimed to estimate temporal trends in the proportion of HIV diagnoses which could be characterized as recent infections in Australia for men who have sex with men (MSM), people who inject drugs (PWID), and heterosexual men and women using modified back-projection methodology based on data sources from HIV/AIDS Surveillance database. The proportion of HIV diagnoses among MSM that can be classified as recent infections increased in MSM, heterosexual men and women consistently. However, after initial increases during 1996–2000, the proportion of overall recent infections estimated among PWID declined by 50% in 2007 compared to 2000 (from 23 to 11%). These data suggest that late HIV diagnoses were more common among PWID compared to other groups. Ongoing prevention efforts need to be coupled with targeted testing and treatment efforts to increase the diagnosis of recent infection in PWID and reduce apparent inequities in access to screening.     

Adapting the VOICES HIV Behavioral Intervention for Latino Men Who Have Sex with Men

Latino men who have sex with men (MSM) are disproportionately impacted by HIV/AIDS, but few behavioral interventions address their prevention needs. Adaptation of evidence-based interventions is a pragmatic strategy that builds upon lessons learned and has the potential to fill gaps in prevention programming. Yet there are few reports of how transfers are executed and whether effectiveness is achieved. This research reports on the adaptation of VOICES/VOICES, a single-session intervention designed for heterosexual adults, into No Excuses/Sin buscar excuses for Latino MSM. To test the adapted intervention, 370 at-risk Latino MSM were enrolled in a randomized trial. At a three-month follow-up, there was a sharper decrease in unprotected intercourse in the intervention group compared to controls (59 % vs. 39 %, ANOVA p < 0.05, F = 4.10). Intervention participants also reported more condom use at last intercourse (AOR = 1.69; 95 % CI 1.02–2.81, p < 02). Findings support use of adapted models for meeting prevention needs of high-priority populations.     

High HIV Risk but Inadequate Prevention Services for Men in China Who Have Sex with Men: An Ethnographic Study

China is facing an emerging HIV epidemic among men who have sex with men (MSM). However, the HIV risk and prevention needs of these men are not well understood. We conducted in-depth qualitative interviews between August and October 2000 with 38 persons who identified as being MSM or knowledgeable about the MSM population in Beijing. Our ethnographic study identified 20 different segments of the population of MSM in Beijing and 14 distinct types of venues where these men congregate. Despite high levels of sexual risk taking, few men perceived themselves to be at risk for HIV. The main reasons cited for engaging in unsafe sex were economic survival, misconceptions about HIV, inaccurate assessment of a partner's risk, trusting a partner or needing to prove a partner trustworthy, meeting an attractive partner, and cruising in public sex environments. The HIV prevention services currently available in Beijing include mass media education, hotline information and counseling services, venue-based outreach, hospital-based services, and Internet sites, but few of these programs specifically targeted the MSM population. The major barriers to utilizing exiting services were lack of perceived risk, lack of privacy and anonymity, uninteresting program content, and distrust and questionable credibility of providers. Programs need to address issues broader than AIDS, be peer-designed and peer-led, be entertaining, and receive more government support. Our data suggest that many MSM are at high risk for HIV, but receive inadequate services. More effective and sustainable programs must be developed and implemented to prevent the further spread of HIV in this population.     

Online Sex-Seeking Behaviors Among Men Who have Sex with Men: Implications for Investigation and Intervention

To investigate factors associated with online sex-seeking behaviors among men who have sex with men (MSM) in Beijing, China. MSM participants were recruited from two cohort studies with multiple enrollment methods from November 2006 to February 2007 and from March to June 2008, respectively. Data collected included demographics and sexual behaviors. Of the 901 participants, 68.1% were single; 69.3% were non-Beijing residents; 94.4% considered themselves to be homosexual; 65.2% received college or higher levels of education; the median age was 26 years; 73.0% sought male sex partners via the Internet in the past 3 months; 66.2% had ≥2 sex partners. Younger age, higher levels of education and having had ≥2 male sex partners in the past 3 months were independently associated with seeking sex partners on the Internet. These findings indicate that Internet-based intervention programs could encourage younger high-risk MSM to use condoms and reduce their numbers of sexual partners.     

Prospective Predictors of Unprotected Anal Intercourse Among HIV-Seropositive Men Who Have Sex with Men Initiating Antiretroviral Therapy

Contemporary HIV prevention efforts are increasingly focused on those already living with HIV/AIDS (i.e., “prevention with positives”). Key to these initiatives is research identifying the most risky behavioral targets. Using a longitudinal design, we examined socio-demographic and psychosocial factors that prospectively predicted unprotected anal intercourse (UAI) in a sample of 134 HIV-seropositive men who have sex with men (MSM) initiating, changing, or re-starting an antiretroviral therapy regimen as part of a behavioral intervention study. Computer-based questionnaires were given at baseline and 6 months. In a sequential logistic regression, baseline measures of UAI (step 1), socio-demographic factors such as Latino ethnicity (step 2), and psychosocial factors such as crystal methamphetamine use, greater life stress, and lower trait anxiety (step 3) were predictors of UAI at 6 months. Problem drinking was not a significant predictor. Prevention efforts among MSM living with HIV/AIDS might focus on multiple psychosocial targets, like decreasing their crystal methamphetamine use and teaching coping skills to deal with life stress.

金华市MSM队列HIV阳转及高危行为变化情况

目的了解金华市男男性行为人群（MSM）的艾滋病病毒（HIV）抗体阳转及高危行为变化情况。方法采用前瞻性队列研究,招募符合纳入标准的MSM组建队列。纳入队列的MSM每隔3个月进行一次随访调查,并采集血样检测HIV抗体。结果共纳入90名HIV抗体阴性的MSM,队列基线调查艾滋病防治核心知识知晓率为83.3%,队列保持率为78.9%（71/90）,比较基线调查和随访到的性行为情况,随着随访次数增加,最近3个月与同性性伴发生安全性行为所占构成比增加;最近3个月与固定同性性伴和临时同性性伴发生性行为时都采取保护措施的比例有明显提高,与异性性伴发生性行为时安全套使用情况无变化。HIV血清抗体阳转率为3.9/100人年。结论参与队列定期随访和检测后,MSM的高危性行为有所下降。由MSM社会组织鼓励动员参加定期随访和检测是值得推广的有效干预措施。     

Psychosocial,Behavioral, and Cultural Predictors of Sexual Risk for HIV Infection Among Latino Men Who Have Sex with Men

This study sought to replicate and extend an investigation by Diaz et al. (1999) on determinants of HIV risk among Latino gay and bisexual men living in San Francisco who were predominantly English-speaking. Compared to the Diaz et al. study, the current study sample consisted of predominantly Spanish-speaking MSM, who resided outside of HIV/AIDS epicenters and whose countries of origin were primarily Central & South American. The relationships of unprotected anal sex and multiple sexual partners with demographic, developmental, behavioral, cultural and psychosocial variables were examined. Data were collected in a convenience sample of 250 participants (primarily immigrants from El Salvador) residing in Virginia. Most men in the sample had more than one sexual partner in the last 3 months (62%) and more than a third had unprotected anal sex with a casual partner in the same time period. Communication about HIV, sexual attraction, machismo, and experiences of discrimination based on homosexual behavior were predictive of HIV risk behaviors. The findings support an integrative approach to investigating HIV risk among Latino MSM. Implications for prevention programs are discussed.     

HIV Prevention Altruism and Sexual Risk Behavior in HIV-Positive Men Who Have Sex with Men

An understanding of men's motivations to avoid risk behavior is needed to create efficacious HIV prevention programs for HIV-positive men who have sex with men (MSM). This study investigates the relationship between sexual risk behavior and HIV prevention altruism, which is defined as the values, motivations, and practices of caretaking towards one's sexual partners to prevent the transmission of HIV. In a sample of 637 HIV-positive MSM, HIV prevention altruism significantly protects against serodiscordant unprotected anal intercourse (SDUAI) in crude analysis, but not after adjustment for drug use and compulsive sexual behavior. HIV prevention altruism is also related to not engaging in anal intercourse, but is not related to serodisclosure to secondary partners. Lack of altruism appears related to sexual risk behavior in HIV-positive MSM, although other psychological and contextual factors play significant roles. The promotion of HIV prevention altruism may provide a formidable new direction for HIV prevention programs.     

Men Who have Sex with Men: Racial/Ethnic Disparities in Estimated HIV/AIDS Prevalence at the State and County Level, Florida

Population-based HIV/AIDS prevalence estimates among men who have sex with men (MSM) have been unavailable, but have implications for effective prevention efforts. Prevalent (living) Florida HIV/AIDS cases reported through 2006 (numerators) were stratified by race/ethnicity and HIV exposure category. Based on previous research, MSM populations were posited as 4–10% of all males aged ≥13 years in each subgroup (denominators). At the estimated lower and upper plausible bounds, respectively, HIV/AIDS prevalence per 100,000 MSM was significantly higher among black (8,292.6–20,731.4); Hispanic (5,599.5–13,998.7); and Asian/Pacific Islander, American Indian or multi-racial (4,942.6–12,356.8) MSM than among white MSM (3,444.9–8,612.3). HIV/AIDS prevalence among all MSM was 13.8–36.9 times that among all other males. Across 19 high-morbidity counties, MSM HIV/AIDS prevalence was highest among those in the most populous counties and highest among blacks. This methodology, adaptable by other states, facilitates calculation of plausible MSM HIV/AIDS prevalence to guide HIV prevention/care community planners and MSM.     

Vengeance,Condomless Sex and HIV Disclosure Among Men Who Have Sex with Men Living with HIV

Vengeance has been shown to be a risk factor for HIV nondisclosure. Research examining the associations between vengeance, condomless sex, and HIV nondisclosure is lacking. The aim of the current study was to explore the association between vengeance, condomless sex and disclosure (behavior, attitude and intention) among men who have sex with men (MSM) living with HIV. Participants included 266 MSM who were a part of a disclosure intervention study. Men were recruited from local and state AIDS service organizations (ASOs), HIV-related venues and forums, and at local eating and drinking establishments in Tampa, Florida, and Columbus and Dayton, Ohio metropolitan statistical areas (MSAs). Advertisements were also placed in local daily newspapers. Vengeance was operationalized into three groups based on percentiles (least, more, and most vengeful) and as a continuous variable. Crude and multivariable logistic regression models were used to examine the association between vengeance and condomless sex in the past 30 days. Simple and multiple linear regression models were used to determine the association between vengeance and HIV disclosure. After adjusting for demographic and geographic characteristics, participants who were “most vengeful” had, on average, an approximate six-point decrease (β: ?5.46; 95% CI ?9.55, ?1.36) in disclosure intention compared to MSM who were “least vengeful.” Prevention and intervention programs geared towards improving disclosure among MSM should address vengeance.

Efficacy of an HIV/STI Prevention Intervention for Black Men Who Have Sex with Men: Findings from the ManyMen, ManyVoices (3MV) Project

Black men who have sex with men (MSM) in the United States experience disproportionately high rates of HIV and other sexually transmitted infections (STIs); however, the number of evidence-based interventions for Black MSM is limited. This study evaluated the efficacy of Many Men, Many Voices (3MV), a small-group HIV/STI prevention intervention developed by Black MSM-serving community-based organizations and a university-based HIV/STI prevention and training program. The study sample included 338 Black MSM of HIV-negative or unknown HIV serostatus residing in New York city. Participants were randomly assigned to the 3MV intervention condition (n = 164) or wait-list comparison condition (n = 174). Relative to comparison participants, 3MV participants reported significantly greater reductions in any unprotected anal intercourse with casual male partners; a trend for consistent condom use during receptive anal intercourse with casual male partners; and significantly greater reductions in the number of male sex partners and greater increases in HIV testing. This study is the first randomized trial to demonstrate the efficacy of an HIV/STI prevention intervention for Black MSM.     

Feasibility and Promise of a Couple-Based HIV/STI Preventive Intervention for Methamphetamine-Using,Black Men Who have Sex with Men

Accumulating evidence supports couple-based approaches for HIV/STI preventive interventions. Yet, to date, no studies have examined couple-based sexual risk reductions intervention specifically for men who have sex with men (MSM) from populations with elevated rates of HIV/STI transmission, such as black MSM and methamphetamine-involved MSM. We pilot tested—using a pre-/post-test design—a seven-session couple-based intervention for black, methamphetamine-using, black MSM couples engaging in sexual risk. Feasibility was assessed via recruitment and retention rates; potential efficacy relied on self-reported sexual risk and drug use prior to and two months following intervention delivery. We enrolled 34 couples (N = 68 men). Over 80% attended all seven intervention sessions, and retention exceeded 95% at two-month follow-up. At follow-up, participants reported significantly fewer sexual partners, fewer episodes of unprotected anal sex, and greater condom use with their main partner; participants also reported significantly less methamphetamine use, any illicit drug use, and number of illicit drugs used. These findings indicate that couple-based HIV/STI intervention is feasible and promising for at-risk black MSM couples.     

Potential Bridges for HIV Infection to Men Who Have Sex With Men in Guangzhou,China

To assess the potential for HIV acquisition among men who have sex with men (MSM) in Guangzhou, China, we conducted a cross-sectional, anonymous, face-to-face survey of MSM in the metropolitan area of Guangzhou, China. As a pilot recruitment for a cohort study, participants were recruited by convenience sampling through newspaper and television advertising, website information, and respondent referral. Blood samples were tested for HIV, hepatitis B (HBV), hepatitis C (HCV), and syphilis. Client-centered HIV and STD counseling was provided.A total of 201 MSM were interviewed and 200 blood samples were tested. The prevalence of HIV antibody was 0% (97.5% CI 0–1.8%); 17.5% of MSM were HBV surface antigen positive; 1.0% had HCV antibodies; 10.5% had antibodies to syphilis. Syphilis seropositivity was associated with sex with a foreign MSM in the last six months and 10.4% reported sex with a foreign MSM overall. The majority (54.7%) reported unprotected anal sex with other men. Nearly one-third (31.8%) had regular female partners; 25.9% were currently married to a woman; 6% had casual female partners; 4.5% had sex with a female sex worker; 4.5% had sex with a male sex worker; and 12.9% had unprotected vaginal sex and unprotected anal sex with a man in the past six months. Only one MSM reported injection drug use (0.5%). The currently low prevalence of HIV but high level of unprotected anal sex, high prevalence of syphilis infection, and sexual networks that include foreign MSM point to a transient window for HIV prevention among MSM in Guangzhou. We recognize challenges to recruiting a representative sample of MSM and retaining them in longitudinal cohort studies.     

HIV Prevalence and Correlates of Unprotected Anal Intercourse Among Men Who Have Sex with Men, Jinan, China

China’s HIV epidemic may be shifting towards predominantly sexual transmission and emerging data point to potential increases in HIV prevalence among men who have sex with men (MSM). There is particular need to assess the extent of risk behavior among MSM outside of China’s most cosmopolitan cities. We conducted a respondent-driven sampling survey (N = 428) to measure HIV seroprevalence and risk behavior among MSM in Jinan, China, the provincial capital of Shandong. HIV prevalence was 0.5% (95% confidence interval [CI] 0.1–1.0). Unprotected anal intercourse (UAI) in the last 6 months (reported by 61.4%) was associated with buying or selling sex to a man in the last 6 months, syphilis infection, multiple partners in the last month, low HIV knowledge and migrant status. No participant had previously tested for HIV. Risk for HIV transmission is widespread among MSM throughout China; basic prevention programs are urgently needed.
