Differences in HIV risk behaviors among black and white men who have sex with men

OBJECTIVES: Surveillance findings consistently indicate that black men who have sex with men (MSM) experience a disproportionate burden of HIV/AIDS compared with white MSM. This study tested the hypothesis that black MSM engage in greater levels of HIV risk behaviors than white MSM and sought to determine if self-reported HIV serostatus moderated any of the observed differences. METHODS: A cross-sectional study of MSM was conducted by recruiting men from gay-identified venues in a large metropolitan area of the southern United States. Data were collected by face-to-face interview. RESULTS: The hypothesis was only supported for one measure of HIV risk behavior: The average number of main (steady) sex partners in the past year was significantly greater among black men (P < 0.0001). However, black and white MSM did not significantly differ in unprotected sex with serodiscordant partners. Racial differences in sexual risk behavior were found only for HIV-negative men and indicated greater protective behavior for black men. DISCUSSION: These findings suggest that fewer black MSM, compared with white MSM, engage in HIV sexual risk behaviors but only among HIV-negative men. Identifying the epidemiologic dynamics driving HIV infection among black MSM that go beyond individual-level risk behaviors may be warranted.     

Men who have sex with men and human immunodeficiency virus/sexually transmitted disease control in China

OBJECTIVES: To address the role of men who have sex with men (MSM) in the human immunodeficiency virus (HIV)/sexually transmitted disease (STD) epidemic in China. GOAL: To explore the prevalence of risky sexual behaviors and the existing prevention efforts among men who have sex with men (MSM) in China. STUDY DESIGN: Review of behavioral and STD/HIV prevention studies addressing MSM in China. RESULTS: Sexual risk behaviors including unprotected group sex, anal sex, casual sex, and commercial sex were prevalent among Chinese MSM. Many Chinese MSM also engaged in unprotected sex with both men and women. Most MSM either did not perceive that they were at risk of HIV/AIDS or underestimated their risk of infection. Surveillance and intervention research among these men are still in the preliminary stages. CONCLUSIONS: Chinese MSM are at risk for HIV/STD infection and potential transmission of HIV to the general population. In addition to sexual risk reduction among MSM, reduction of homosexuality- related stigma should be part of effective intervention efforts. Volunteers from the MSM community and health care workers in primary health care system may serve as valuable resources for HIV/STD prevention and control among MSM.     

Prevalence of bisexual behaviors among men who have sex with men (MSM) in China and associations between condom use in MSM and heterosexual behaviors

OBJECTIVES: This study investigated the prevalence of bisexual behaviors and marital status among Chinese men who have sex with men (MSM) and the associations between MSM's condom use and their heterosexual behaviors. METHODOLOGY: Eight hundred ninety-six adult males in Yunnan Province, China, who reported to ever have engaged in MSM behaviors were interviewed. Data were acquired through the China-UK HIV/AIDS Prevention and Care Project from 2003 to 2006. RESULTS: Of all respondents, one-third had ever been married, 59% had ever engaged in bisexual behaviors, and 31% had done so in the past 6 months. High prevalence of inconsistent condom use was reported in heterosexual behaviors (71.9%), as well as with those who had engaged in MSM sexual behaviors in the past 6 months (30.8% with commercial sex workers and 54.7% with noncommercial sex partners) in the past 6 months. Those who did not use condoms with MSM partners were also more likely than others to not use condoms with their female sex partners (FSP). Those who had voluntary counseling and testing services were more likely than others to have used a condom in the last episode of sex with their FSP (multivariate odds ratio = 1.66). CONCLUSIONS: The clustering of unprotected sexual behaviors with male and FSP among bisexual MSM is revealed. The bridging effects of the risk for human immunodeficiency virus transmission from the MSM population to the female population are evident.     

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.

Incidence of sexually transmitted diseases and HIV infection related to perceived HIV/AIDS threat since highly active antiretroviral therapy availability in men who have sex with men

OBJECTIVE: Concerns have been expressed regarding increase in risky sex because of the availability of antiretroviral treatments in Western countries. GOAL: The goal of this longitudinal study was to investigate the association between highly active antiretroviral therapy (HAART)- and postexposure prophylaxis-related beliefs and the incidence of sexually transmitted diseases (STDs) and new HIV infections in men who have sex with men (MSM). STUDY: Data on the incidence of STDs and new HIV infection, and the level of agreement with different HAART- and PEP-related beliefs from 151 HIV-negative MSM were compiled. RESULTS: Of all MSM, 65.6% tested negative for any STDs and 7 men HIV seroconverted. Perceiving less HIV/AIDS threat since HAART availability and younger age were significantly associated with a higher incidence of STDs. Perceiving less need for safe sex since HAART availability was significantly associated with an increased likelihood of HIV seroconversion. CONCLUSIONS: The results support the assumption that there is an association between the incidence of STDs and a decreased perception of HIV/AIDS threat resulting from HAART availability. Less perceived need for safe sex since HAART availability was associated with HIV seroconversion.

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.     

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.
