HIV Prevalence and Risk Behaviours from Three Consecutive Surveys Among Men Who Have Multiple Female Sexual Partners in Cape Town

HIV bio-behavioural surveillance surveys conducted at regular intervals are critical for monitoring of, and informing a targeted response to the HIV pandemic. We used Respondent-driven Sampling in 2006, 2008 and 2010 to recruit men who have multiple female sexual partners. We performed several logistic regression analyses to compare HIV sexual risk behaviours, and HIV infection over time. Decreases in inconsistent condom use with main partners were not sustained in 2010. Inconsistent condom use with non-main partners, partner numbers and having one-time partners continued to decrease over time. Levels of alcohol consumption in 2010 reverted to a level higher than in 2006. Non-significant increases in HIV prevalence and reporting a symptom of a sexually transmitted infection (STI) were found. The decrease in numbers of and one-time sexual partners, and in inconsistent condom use with non-main partners augers well for decreasing HIV incidence among men in the study community, but might be offset by decreases in consistent condom use with main partners, and increases in alcohol consumption and STIs.     

HIV Risk Behaviours and their Relationship to Intimate Partner Violence (IPV) Among Men Who Have Multiple Female Sexual Partners in Cape Town,South Africa

HIV/AIDS and intimate partner violence (IPV) are growing public health concerns in South Africa. Knowledge about adult men’s perpetration of IPV and links between HIV risk behaviours and IPV is limited. Respondent driven sampling was used to recruit men who have multiple concurrent female sexual partners. Forty-one percent of the 428 recruited men had perpetrated IPV. Inconsistent condom use was associated with physical IPV; experiencing a symptom of a sexually transmitted infection and engaging in transactional sex were associated with physical and sexual IPV; problem alcohol use was associated with physical, and any IPV, but not sexual IPV; having five or more partners was associated with sexual IPV; perceptions of partners’ infidelity were associated with physical and any IPV. HIV risk reduction interventions among men, especially those with multiple female sex partners, should incorporate strategies to change the underlying construction of masculinity that combines the anti-social and risky behaviours of IPV perpetration, inconsistent condom use, transactional sex and heavy alcohol consumption.     

HIV Prevalence and Related Risk Factors in Men Who Have Sex with Men in Bamako,Mali: Findings from a Bio-behavioral Survey Using Respondent-Driven Sampling

Using respondent driven sampling, we conducted a cross-sectional bio-behavioral survey among men who have sex with men (MSM) in Bamako, Mali. Eligibility criteria included age ≥18 years and having had sex with another man in the last 6 months. We enrolled 552 MSM, 99.6% were tested for HIV. MSM in Bamako were young (69.6% ≤24 years) and educated (63.7% ≥secondary). HIV prevalence among MSM in Bamako was 13.7; 90.1% of HIV-infected men were unaware of their HIV status. Almost one-third had never been tested for HIV. Factors associated with higher odds of HIV included younger age, being receptive with last partner, condom breaking during anal sex in last 6 months, talking to peer educator about HIV, and having sexually transmitted infection symptoms in past year. The results suggest the need for enhanced HIV prevention and treatment services targeted at MSM in Bamako, with emphasis on repeated HIV testing.     

HIV Risk and Prevention Behaviors in Men Who Have Sex With Men and Women: A Respondent-Driven Sampling Study in Shenzhen,China

Men who have sex with men and women (MSMW) may expand the HIV epidemic from men who have sex with men to the female population. From a respondent-driven sampling survey in Shenzhen, China, we quantified the burden of HIV/syphilis and studied patterns of risk and prevention behaviors in 107 MSMW, and compared these with those of 542 men who have sex with men only (MSM-only). HIV prevention behaviors and consistent condom use with male partners did not differ between the two groups. However, HIV risk behaviors were more common among MSMW than MSM-only. Moreover, among MSMW, the HIV prevalence was as high as 6 % and consistent condom use was extremely low with female partners in MSMW. We conclude that there is risk of HIV transmission from MSMW to the female population. Special efforts are needed to convince MSMW they should refrain from HIV risk behaviors.     

Possible Increase in HIV and Syphilis Prevalence Among Men Who Have Sex with Men in Guangzhou, China: Results from a Respondent-Driven Sampling Survey

A respondent-driven sampling survey was conducted to investigate HIV related serological and behavioral characteristics of men who have sex with men (MSM) in Guangzhou, China, and to identify associated factors potentially driving the epidemic. Respondent- Driven Sampling Analysis Tool and SPSS were used to generate adjusted estimates and to explore associated factors. Three hundred seventy-nine eligible participants were recruited. The adjusted prevalence of HIV and current syphilis infection are 5.2% and 17.5% respectively. 60.3% have unprotected anal sex in the past 6 months. Unprotected anal sex, having receptive anal sex and current syphilis infection are significant factors associated with HIV infection. The potential for a rapid rise of HIV and syphilis infections among MSM in Guangzhou exists. Targeted interventions with voluntary counseling and testing (VCT) and sexually transmitted infection (STI) services are needed to address the epidemic, with a focus on such subgroups as those of with current syphilis, and non-official Guangzhou residence status.     

Sexual Risk Taking,STI and HIV Prevalence Among Men Who Have Sex with Men in Six Indonesian Cities

Using surveillance data on men who have sex with men (MSM) from six Indonesian cities, this article reports prevalence of sexual risk taking, HIV and other sexually transmitted infections. Factors associated with HIV, other STIs and consistent condom use were assessed. Behavioral data were collected from 1,450 MSM, among whom 749 were tested for HIV and syphilis and 738 for gonorrhea and Chlamydia. Associations were assessed using multivariate logistic regression. Over 80% of MSM knew HIV transmission routes, 65% of MSM had multiple male sexual partners, 27% unprotected anal sex with multiple male partners, and 27% sex with a female in the prior month. Consistent condom use ranged from 30 to 40% with male partners and 20 to 30% with female partners, depending upon partner type. HIV prevalence averaged 5.2%, but was 8.0% in Jakarta. Prevalence of rectal gonorrhea or Chlamydia was 32%. Multivariate analyses revealed recent methamphetamine use and current rectal gonorrheal or chlamydial infection to be associated with HIV infection. The data confirm diverse sexual networks and substantial sexual risk-taking, despite relatively high levels of education and HIV-related knowledge. In addition to promoting partner reduction and more consistent condom and lubricant use, prevention efforts must also address substance abuse.     

Middle-Aged and Older Men Who Have Sex With Men Exhibit Multiple Trajectories With Respect to the Number of Sexual Partners

This study aimed to examine trajectories with respect to the number of sexual partners among older men who have sex with men and to determine characteristics associated with trajectory groups. Nagin’s group-based modeling was used to identify trajectories for 237 men from the Pitt Men’s Study with respect to the number of male intercourse partners from age 50.0 to 59.5. Three distinct trajectory groups were identified. Most men (69.2%) had a median of two sexual partners in the past 6 months across the age range of the study. A smaller group (19.4%) had low or no sex partners. The smallest group (11.4%) had 30 or more sexual partners in the past 6 months at age 50. The groups were statistically different with respect to race, HIV status, drug use (marijuana, poppers, crack cocaine, and Viagra), the number of unprotected anal sex partners, and personal attitudes towards sex.     

Seeking Male Sexual Partners via Internet and Traditional Venues among Chinese Men Who Have Sex with Men: Implications for HIV Risk Reduction Interventions

The dynamic nature of finding male sexual partners (sex-finding) among Chinese men who have sex with men (MSM) may play a substantial role in the HIV epidemic. We compared characteristics and behaviors of MSM who mostly sought sex via the Internet versus traditional venues in a cross-sectional survey among 3588 Chinese MSM. We assessed the sociodemographic predictors and compared high-risk behaviors of using Internet versus traditional venues for sex-finding. Compared to non-Internet MSM, Internet-user MSM were more likely to have been: younger, currently single, better educated, health-insured, with higher income, with Beijing residency (‘Hukou’), living longer in the city, HIV-positive, ever using drug and engaging in condomless receptive anal sex. Internet sex-finding users were less likely to be sexually active for longer duration, drink alcohol, drink alcohol before sex, or ever have sex with women. Knowledge of differential characteristics of various sex-finding MSM can help design targeted interventions.     

HIV Prevalence and Sexual Risk Behaviors Associated with Awareness of HIV Status Among Men Who Have Sex with Men in Paris, France

A cross-sectional survey, using self-sampled finger-prick blood on blotting paper and anonymous behavioral self-administrated questionnaires was conducted in Paris in 2009 among MSM attending gay venues. Paired biological results and questionnaires were available for 886 participants. HIV seroprevalence was 17.7 % (95 % CI: 15.3–20.4). Four groups were identified according to their knowledge of their HIV biological status. Among the 157 found to be seropositive, 31 (19.7 %) were unaware of their status and reported high levels of sexual risk behaviors and frequent HIV testing in the previous 12 months. Among the 729 MSM diagnosed HIV-negative, 183 were no longer sure whether they were still HIV-negative, or had never been tested despite the fact that they engaged in at-risk sexual behaviors. This study provides the first estimate of HIV seroprevalence among MSM in Paris and underlines the specific need for combined prevention of HIV infection in this MSM population.     

HIV Risk Behaviors Among Black/African American and Hispanic/Latina Female Partners of Men Who Have Sex With Men and Women

We examined the frequencies of HIV-related risk factors among women reporting and not reporting sex with a man who has sex with men and women (MSMW). We used data from 15,625 visits of Black and Hispanic/Latina females, ages 15–64 years, to Los Angeles County HIV testing sites (2007–2008). The following risk factors were associated with reporting an MSMW partner: number of sex partners, use of party drugs, anal sex, and sexual partners with other risk factors. Overall, females who reported an MSMW partner differed little in their likelihood of testing HIV positive (0.93%) compared to those who did not (0.58%, p value = 0.19). Among females reporting one male sex partner, having an MSMW partner was strongly associated with HIV (2.8 vs. 0.63%, p = 0.03). Interventions targeting women who report other risky behaviors may reach many who have been with MSMW. Women with one partner are an important focus of such efforts.     

Stigmatizing Policies Interact with Mental Health and Sexual Behaviours to Structurally Induce HIV Diagnoses Among European Men Who Have Sex with Men

AIDS and Behavior - Structural stigma shapes men who have sex with men’s (MSM’s) mental health and sexual behaviours. The aim of this study was to examine how stigmatizing policies...     

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.     

Intimate Partner Violence and HIV Sexual Risk Behaviour Among Women Who Inject Drugs in Indonesia: A Respondent-Driven Sampling Study

Women who inject drugs are disproportionately affected by HIV and intimate partner violence (IPV); however, the link between IPV and HIV remains under-researched among substance-using women in low- and middle-income countries. This study examined associations and additive effects of different forms of IPV victimization (psychological, physical and/or injurious, and sexual) on HIV sexual risk behavior among women who inject drugs in Indonesia. Respondent-driven sampling (RDS) was used to recruit 731 women from Greater Jakarta and Bandung, West Java. RDS-II weighted prevalence of any past-year IPV was 68.9% (95% CI 65.0, 72.6) in Jakarta and 55.9% (95% CI 48.0, 63.5) in Bandung. In separate logistic regressions controlling for socio-demographic covariates, all three forms of IPV showed statistically significant associations with sexual risk behavior. After adjusting for all IPV types, psychological (OR 1.87; 95% CI 1.17, 2.99; p?=?0.009) and sexual (OR 1.98; 95% CI 1.22, 3.21; p?=?0.006) IPV independently predicted women’s sexual risk behavior. Marginal effects models suggested that co-occurrence of multiple forms of IPV had greater adverse consequences: sexual risk behavior was reported by 64.1% of women who did not experience any IPV, but increased to 89.9% among women exposed to all three types. Comprehensive harm reduction services that integrate IPV monitoring and prevention are urgently needed to reduce both HIV and IPV.     

Psychosocial Characteristics and Sexual Behaviors of People in Care for HIV Infection: An Examination of Men Who Have Sex with Men, Heterosexual Men and Women

Few studies have examined the psychosocial factors associated with sexual transmission behaviors among HIV-positive men who have sex with men (MSM), heterosexual men (MSW) and women. We enrolled 1,050 sexually active HIV-positive patients at seven HIV clinics in six US cities as part of a clinic-based behavioral intervention. We describe the sexual transmission behaviors and examine demographic, clinical, psychosocial, and clinic prevention variables associated with unprotected anal or vaginal intercourse (UAVI). Twenty-three percent of MSM, 12.3% of MSW and 27.8% of women engaged in UAVI with partners perceived to be HIV-negative or of unknown serostatus. Among MSM and MSW, having multiple partners and lower self-efficacy were associated with increased odds of UAVI. Self-rating one’s health status as excellent/very good was a risk factor for UAVI among MSM. Among women, binge drinking and stressful life events were associated with UAVI. These findings identify variables that warrant attention in targeted interventions.     

HIV Testing and Preventive Services Accessibility Among Men Who Have Sex With Men at High Risk of HIV Infection in Beijing,China

The HIV epidemic among men who have sex with men (MSM) has been increasing at an alarming rate in most areas of China in recent years. Many Chinese MSM still lack sufficient access to HIV prevention services, despite ongoing scale-up of comprehensive HIV testing and intervention services. The purpose of this study was to investigate utilization of HIV testing and prevention services, and related factors that influence the MSM people to access HIV test or other services to prevent HIV among MSM in Beijing, China.Three successive cross-sectional surveys of MSM were conducted in Beijing from September 2009 to January 2010, September 2010 to January 2011, and September 2011 to January 2012. Demographic and behavioral data were collected and analyzed. Blood samples were tested for HIV and syphilis. Three models were established to analyze factors associated with HIV testing and preventive services.Of the 1312 participants, prevalence of HIV and syphilis was 7.9% and 15.4%, respectively. Sixty-nine percent ever had an HIV test, 56.2%, 78.7%, and 46.1% received HIV test, free condom/lubricants, and sexually transmitted infection services in the past 12 months (P12M), respectively. MSM with larger social networks and who knew someone infected with HIV were more likely to receive HIV testing and preventive services; lower degrees of stigma and discriminatory attitudes toward HIV/AIDS were positively associated with having an HIV test, whereas unprotected anal intercourse in the past 6 months (P6M) was associated with less preventive services participation. The most reported barriers to HIV testing were fear of testing HIV positive (79.3%) and perceiving no risk for HIV (75.4%). Almost all participants felt that ensuring confidentiality would encourage more MSM to have an HIV test. The two main reasons for not seeking HIV test was not knowing where to go for a test (63.2%) and perceiving low risk of HIV infection (55.1%).Given a high prevalence of HIV, syphilis, and risky behaviors and a relatively low HIV testing rate among MSM in Beijing, more efforts are urgently needed to address barriers to HIV testing and improve accessibility of prevention services.     

HIV and Sexual Risk Among Men Who Have Sex With Men and Women in Asia: A Systematic Review and Meta-Analysis

We performed a systematic review to estimate the proportion of men who have sex with men (MSM) in Asia who are bisexual and compare prevalence of HIV and sexual risk between men who have sex with men and women (MSMW) and men who have sex with men only (MSMO). Forty-eight articles based on 55 unique samples were identified from nine countries in Asia. Bisexual behaviour was common among MSM (pooled prevalence 32.8 %). Prevalence of HIV (pooled OR 0.90; 95 % CI 0.77–1.05), recent syphilis infection (pooled OR 0.99; 95 % CI 0.93–1.06) and unprotected anal intercourse (pooled OR 0.80; 95 % CI 0.57–1.11) were similar between MSMW and MSMO, but heterogeneity was high. MSMW had lower odds of reporting a prior HIV test than MSMO (OR 0.82; 95 % CI 0.70–0.95; p = 0.01, I² = 0 %). Targeted interventions are needed to increase uptake of HIV testing among MSMW. Increased reporting of disaggregated data in surveillance and research will help improve understanding of risk in MSMW and inform targeted interventions.     

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.
