HIV, syphilis infection, and sexual practices among transgenders, male sex workers, and other men who have sex with men in Jakarta, Indonesia

OBJECTIVES: To establish the prevalence of HIV, syphilis, and sexual risk behaviour among three groups of men who have sex with men in Jakarta, Indonesia, and to investigate sexual links between these men and broader heterosexual populations. METHODS: Anonymous, cross sectional surveys among community recruited transgender and male sex workers and self recognised men who have sex with men (MSM) were undertaken in mid-2002 in Jakarta, Indonesia. Places where transgender and male sex workers sell sex and where men go to meet non-commercial male sex partners were mapped. Probability samples were selected for the sex worker populations, while a mixed probability and convenience sample was drawn for self recognised MSM. Blood was drawn for HIV and syphilis serology and community interviewers administered a standardised questionnaire. RESULTS: HIV prevalence was 22% among transgender sex workers, 3.6% among male sex workers, and 2.5% among self recognised MSM, and syphilis prevalence was 19.3%, 2.0% and 1.1% respectively. 59.3% of transgender sex workers and 64.8% of male sex workers reported recent unprotected anal intercourse with clients, and 53.1% of other MSM reported unprotected anal sex with male partners. Some 54.4% of male sex workers and 18.3% of other MSM reported female partners in the preceding year. CONCLUSION: HIV has reached substantial levels among transgender sex workers, and is not negligible in other MSM groups. Risk behaviour is high in all subpopulations, and bisexual behaviour is common, meaning the threat of a wider epidemic is substantial. Prevention programmes targeting male-male sex are needed to reduce this threat.

Unsafe sexual behavior and correlates of risk in a probability sample of men who have sex with men in the era of highly active antiretroviral therapy

OBJECTIVE: To assess the levels and correlates of potential exposure to and transmission of HIV in a contemporary, community-based probability sample of men who have sex with men (MSM). METHODS: In 2003, 311 sexually active MSM participated in a random-digit dial telephone survey in Seattle neighborhoods with a high prevalence of MSM. The primary outcomes were potential exposure to and transmission of HIV, defined as unprotected anal intercourse with a man of opposite or unknown HIV status in the preceding 12 months. RESULTS: Fourteen percent of respondents reported being HIV-positive, 77% reported being HIV-negative, and 8% had not been tested. Of 241 HIV-negative MSM, 25 (10%; 95% confidence interval [CI], 7-15%) were potentially exposed to HIV; among 45 HIV-positive MSM, 14 (31%; 95% CI, 20-46%) were potential HIV-transmitters. Among HIV-negative men, the strongest bivariate correlates of potential exposure to HIV were recent bacterial sexually transmitted disease (odds ratio [OR], 5.8), number of recent male sexual partners (OR, 1.01 per partner), recent sex at a bathhouse (OR, 9.1), and recent use of sildenafil (OR, 4.4), amyl nitrite (OR, 6.2), and methamphetamine (OR, 8.0). Among HIV-infected men, the strongest correlates of potential HIV transmission were recent use of amyl nitrite (OR, 3.1), number of recent male sex partners (OR, 1.07 per partner), and having a male spouse or domestic partner (OR, 0.3). CONCLUSIONS: Most MSM knew their HIV status and adopted safer sexual behaviors to reduce their risk of HIV acquisition or transmission. However, 10% of HIV-negative MSM and 31% of HIV-positive MSM recently engaged in behaviors that placed them at high risk for acquiring or transmitting HIV.     

High prevalence of sexually transmitted diseases among men who have sex with men in Jiangsu Province, China

OBJECTIVE:: The objective of this study was to investigate the prevalence of sexually transmitted diseases (STDs), including HIV infection, and sexual risk behaviors among men who have sex with men (MSM) in Jiangsu Province, China. DESIGN:: The authors conducted a cross-sectional study. METHODS:: From February to July 2003, men who attended 10 participating gay bars in five cities in Jiangsu Province were asked to complete a self-administered questionnaire, including measures of alcohol use and sexual risk behaviors. Blood samples and urethral swabs were taken to examine the presence of STDs, including HIV infection. RESULTS:: A total of 144 men were recruited in the study. Forty-six percent of men reported unprotected anal intercourse with their male sexual partners in the past 3 months. No one was found to be HIV-infected, but the prevalence of STDs was high: gonorrhea 2.7%, chlamydial infection 8.0%, nonchlamydial nongonococcal urethritis 27.7%, active syphilis 6.9%, hepatitis B virus infection 9.1%, herpes simplex virus-2 infection 7.8%, and genital warts 13.2%. CONCLUSIONS:: Given that HIV prevalence among MSM in some other parts of China has been as high as 3%, STDs facilitate the transmission of HIV, and high prevalence of STDs and sexual risk behaviors among MSM exist in Jiangsu Province, the potential for the future spread of HIV is of concern, and it is urgent to provide MSMs with STD healthcare services and HIV/AIDS/STD prevention education and intervention.     

Relationship between syphilis and HIV infections among men who have sex with men in Beijing, China

BACKGROUND: Little is known about risk of HIV and other STDs among men who have sex with men (MSM) in China. OBJECTIVE: To survey the prevalence and risk factors of HIV and syphilis and evaluate correlation of two infections among MSM in the Chinese capital city. METHODS: A community-based sample of 526 MSM was recruited in 2005 through Internet advertising, community outreach, and peer referring. Interviewer-administered interviews were conducted to collect information on demographics and sexual and other risk behaviors, and blood samples were collected to test for syphilis and HIV infections. RESULTS: Seventeen (3.2%) participants were HIV seropositive and 59 (11.2%) syphilis seropositive. Sixty-four percent of participants were migrants who did not have Beijing residence. Forty percent had >10 lifetime male sex partners and 28.8% reported having ever had sex with women. Consistent condom use with primary male sex partners ranged from 21% to 24%, with nonprimary male sex partners from 35% to 42%, and with female partners around 33%. Illicit drug use was not common; only 2.5% reported using Ecstasy or ketamine in the past 6 months. Multivariate logistic regression analyses demonstrated that >10 lifetime male sex partners were independently associated with seropositivity of both syphilis (OR, 1.9; 95% CI, 1.1-3.4) and HIV (OR, 4.3; 95% CI, 1.4-13.6). In addition, HIV infection is significantly associated with syphilis seropositivity (OR, 3.8; 95% CI, 1.3-10.8). CONCLUSIONS: High mobility, multiple sexual partners, and high prevalence of unprotected sex behaviors and syphilis infection suggest a potential rapid spread of HIV in Chinese MSM.
