[目的]了解大连市男男性行为者（MSM）的性行为特征、艾滋病病毒（HIV）感染状况及其影响因素,为MSM人群行为干预工作提供依据。[方法]2009年4-6月,在大连市采用定向抽样方法,对402名MSM进问卷调查和HIV抗体检测。[结果]调查402人,最近半年发生同性肛交的357人,占88.81%。这357人中,同性肛交时安全套从未使用的占9.52%,有时使用的占35.29%,每次都用的占55.18%;付钱寻找男男性服务的占2.24%,平均2.38个性伴;提供商业男男性服务的占21.01%,平均服务17人。调查的402人中,最近半年发生异性性行为的136人,占33.83%。这136人中,安全套从未使用的占41.91%,有时使用的占21.32%,每次都用的占36.76%。检测402人,HIV抗体阳性检出率为4.48%,梅毒感染率为13.93%,有4名同时感染HIV和梅毒。多因素非条件Logistic回归分析结果,年龄大、未接受过艾滋病干预服务者是促进HIV感染的因素。[结论]MSM人群存在感染HIV的危险行为,艾滋病干预服务措施有效,中老年MSM是艾滋病预防控制工作的重点人群。     

HIV Testing among Men Who Have Sex with Men-Results of a Telephone Survey

Background.This article describes the testing behavior for human immunodeficiency virus (HIV) antibody among an urban population of men who have sex with men (MSM) and the reasons given for not being tested for HIV.Methods.A random digit dialing telephone survey of men living in selected neighborhoods of Seattle, Washington, was conducted from June through August 1992.Results.Of 603 MSM interviewed, 82% had ever been tested for HIV; 19% of tested men were seropositive. MSM who were older, nonwhite, with lower income, or not currently sexually active were less likely to have been tested. Among nontesters, 57% believed their risk of infection was too low to justify testing; 52% said they had not tested due to fear of learning the result. Testers and nontesters had similar rates of unprotected sexual behavior.Conclusions.Most MSM who had not been tested for HIV believed they were not at risk of infection and/or were fearful of learning the result. To increase the proportion of MSM who test, public health agencies may need to emphasize that unexpected infection does occur and that new therapies are available for those testing positive. Innovative programs may be necessary to reach those who have not yet decided to be tested.     

Population Size Estimates for Men who Have Sex with Men and Persons who Inject Drugs

Understanding geographic variation in the numbers of men who have sex with men (MSM) and persons who inject drugs (PWID) is critical to targeting and scaling up HIV prevention programs, but population size estimates are not available at generalizable sub-national levels. We analyzed 1999–2010 National Health and Nutrition Examination Survey data on persons aged 18–59 years. We estimated weighted prevalence of recent (past 12 month) male-male sex and injection drug use by urbanicity (the degree to which a geographic area is urban) and US census region and calculated population sizes. Large metro areas (population ≥1,000,000) had higher prevalence of male-male sex (central areas, 4.4 % of men; fringe areas, 2.5 %) compared with medium/small metro areas (1.4 %) and nonmetro areas (1.1 %). Injection drug use did not vary by urbanicity and neither varied by census region. Three-quarters of MSM, but only half of PWID, resided in large metro areas. Two-thirds of MSM and two-thirds of PWID resided in the South and West. Efforts to reach MSM would benefit from being focused in large metro areas, while efforts to reach PWID should be delivered more broadly. These data allow for more effective allocation of funds for prevention programs.     

Pervasive Heavy Alcohol Use and Correlates of Increasing Levels of Binge Drinking among Men Who Have Sex with Men,San Francisco, 2011

Heavy episodic drinking, “binge drinking”, is highly prevalent among men who have sex with men (MSM) and is associated with sexual risk behaviors and HIV seroconversion in this population. We characterized the magnitude of binge drinking and explored correlates of increasing levels of binge drinking among MSM in San Francisco. In this study, 67 % of MSM reported binge drinking in the prior year. The mean number of drinking days in the past month was 11.6. On average, we estimate that 2,699,372 drinks are consumed by MSM in San Francisco every month. Increasing levels of binge drinking was independently associated with younger age, modest income, being born in the United States, never accessing alcohol treatment and reporting unprotected insertive anal intercourse. Our findings underscore the need to target effective strategies to address heavy alcohol consumption and highlight the urgent need to develop novel interventions beyond traditional alcohol treatment settings among MSM.     

A Comparison of the Social and Sexual Networks of Crack-Using and Non-Crack Using African American Men who Have Sex with Men

The role of crack cocaine in accelerating the HIV epidemic among heterosexual populations has been well documented. Little is known about crack use as an HIV risk factor among African American men who have sex with men (AA MSM), a group disproportionately infected with HIV. We sought to compare the social and sexual network characteristics of crack-using and non-crack using AA MSM in Baltimore, MD, USA and to examine associations of crack use with sexual risk. Participants were recruited using street-based and internet-based outreach, printed advertisements, word of mouth. Inclusion criteria were being aged 18 years or older, African American or of black race/ethnicity, and have self-reported sex with another male in the prior 90 days. Crack use was operationalized as self-report of crack in the prior 90 days. Logistic regression was used to identify variables that were independently associated with crack use. Of 230 enrolled AA MSM, 37% (n = 84) reported crack use. The sexual networks of crack-using AA MSM were composed of a greater number of HIV-positive sex partners, exchange partners, and partners who were both sex and drug partners and fewer networks with whom they always use condoms as compared to non-crack using AA MSM. Crack use was independently associated with increased odds of bisexual identity and networks with a greater number of exchange partners, overlap of drug and sex partners, and lesser condom use. Results of this study highlight sexual network characteristics of crack-smoking AA MSM that may promote transmission of HIV. HIV interventions are needed that are tailored to address the social context of crack-smoking AA MSM risk behaviors.     

某区男男性行为人群性伴网络特征与高危行为分析

[目的]了解男男性行为（MSM）人群性伴网络特征及该人群中高危性行为的发生情况,探讨性病（STDs）、人类免疫缺陷病毒（HIV）在该人群中传播及向普通人群传播的模式,为开展性病、艾滋病预防控制提供依据。[方法]通过艾滋病自愿咨询检测门诊、同性恋人群活动场所、同性恋QQ群内动员、＂滚雪球＂等途径寻找MSM人群,招募151人,采用面对面匿名问卷调查方式收集信息。[结果]151名被调查者中最近6个月有30人（19.9%）与异性发生过性行为,高危性行为的发生率为53.3%;与同性性活动情况,其中91人（60.3%）有同性固定性伴,76人（50.3%）与非固定同性性伴的人发生过多次男男性行为（简称有多次男性伴）,77人（51.0%）发生过偶遇性行为（简称有偶遇男性伴）,10人（6.6%）从事商业性行为。而在与固定性伴、多次男性伴、偶遇男性伴、商业性行为中高危性行为的发生率依次是69.2%、57.9%、50.6%、70.0%。与固定男性伴高危性行为的发生率高于与偶遇男性伴高危性行为的发生率（P=0.014）。最近6个月有2种及以上性伴类型占58.9%。30名已感染HIV者中有多次男性伴及偶遇男性伴类型的比例分别为53.3%和63.3%;有过多次男性伴、偶遇男性伴性行为者中发生高危性行为的比例分别为50.0%和63.2%。感染HIV者与固定男性伴发生高危性行为的率低于未感染HIV者（P=0.029）。[结论]MSM人群性伴网络复杂多样,高危性行为发生率高。不仅使HIV在该人群中容易传播,且该人群已成为向普通人群传播HIV的＂桥梁＂人群。     

Sexual Partnering and HIV Risk among Black Men Who Have Sex with Men: New York City

Black men who have sex with men (MSM) are disproportionately affected with HIV in the US. Limited event-specific data have been reported in Black MSM to help understand factors associated with increased risk of infection. Cross-sectional National HIV Behavioral Surveillance Study data from 503 MSM who reported ≥1 male sexual partner in the past year in New York City (NYC) were analyzed. Case-crossover analysis compared last protected and last unprotected anal intercourse (UAI). A total of 503 MSM were enrolled. Among 349 tested for HIV, 18% were positive. Black MSM (N = 117) were more likely to test HIV positive and not know their HIV-positive status than other racial/ethnic groups. Case-crossover analysis of 208 MSM found that men were more likely to engage in protected anal intercourse with a first time partner and with a partner of unknown HIV status. Although Black MSM were more likely to have Black male partners, they were not more likely to have UAI with those partners or to have a partner aged >40 years. In conclusion, HIV prevalence was high among Black MSM in NYC, as was lack of awareness of HIV-positive status. Having a sexual partner of same race/ethnicity or older age was not associated with having UAI among Black MSM.

Estimation of HIV Prevalence,Risk Factors,and Testing Frequency among Sexually Active Men Who Have Sex with Men,Aged 18–64 Years—New York City, 2002

Population-based estimates of human immunodeficiency virus (HIV) prevalence and risk behaviors among men who have sex with men (MSM) are valuable for HIV prevention planning but not widely available, especially at the local level. We combined two population-based data sources to estimate prevalence of diagnosed HIV infection, HIV-associated risk-behaviors, and HIV testing patterns among sexually active MSM in New York City (NYC). HIV/AIDS surveillance data were used to determine the number of living males reporting a history of sex with men who had been diagnosed in NYC with HIV infection through 2002 (23% of HIV-infected males did not have HIV transmission risk information available). Sexual behavior data from a cross-sectional telephone survey were used to estimate the number of sexually active MSM in NYC in 2002. Prevalence of diagnosed HIV infection was estimated using the ratio of HIV-infected MSM to sexually active MSM. The estimated base prevalence of diagnosed HIV infection was 8.4% overall (95% confidence interval [CI] = 7.5–9.6). Diagnosed HIV prevalence was highest among MSM who were non-Hispanic black (12.6%, 95% CI = 9.8–17.6), aged 35–44 (12.6%, 95% CI = 10.4–15.9), or 45–54 years (13.1%, 95% CI = 10.2–18.3), and residents of Manhattan (17.7%, 95% CI = 14.5–22.8). Overall, 37% (95% CI = 32–43%) of MSM reported using a condom at last sex, and 34% (95% CI = 28–39%) reported being tested for HIV in the past year. Estimates derived through sensitivity analyses (assigning a range of HIV-infected males with no reported risk information as MSM) yielded higher diagnosed HIV prevalence estimates (11.0–13.2%). Accounting for additional undiagnosed HIV-infected MSM yielded even higher prevalence estimates. The high prevalence of diagnosed HIV among sexually active MSM in NYC is likely due to a combination of high incidence over the course of the epidemic and prolonged survival in the era of highly active antiretroviral therapy. Despite high HIV prevalence in this population, condom use and HIV testing are low. Combining complementary population-based data sources can provide critical HIV-related information to guide prevention efforts. Individual counseling and education interventions should focus on increasing condom use and encouraging safer sex practices among all sexually active MSM, particularly those groups with low levels of condom use and multiple sex partners At the time this work was conducted, Manning and Marx were with the Epidemic Intelligence Service, Office of Workforce and Career Development, Centers for Disease Control and Prevention, Atlanta, GA, USA; Thorpe, Ramaswamy, Hajat, Marx, Karpati, Mostashari, and Pfeiffer are with the New York City Department of Health and Mental Hygiene, New York, NY, USA; Nash is with the Department of Epidemiology and International Center for AIDS Care and Treatment Programs, Columbia Mailman School of Public Health, New York, NY, USA; Manning is with the Massachusetts Department of Public Health, Bureau of Family and Community Health, Boston, MA, USA.

Knowledge,Attitudes, and Sexual Behaviors in HIV/AIDS and Predictors Affecting Condom Use among Men Who Have Sex with Men in South Korea

ObjectivesIn South Korea, men who have sex with men (MSM) are rather understudied, but are known to be at high risk for human immunodeficiency virus infection (HIV)/acquired immunodeficiency syndrome (AIDS). This study was to access HIV/AIDS knowledge, attitudes, and risk behaviors, and to identify the factors of condom use in HIV prevention.MethodsWe recruited 1070 MSM in Korea, using the Internet to maximize the confidentiality of the MSM.ResultsThe prevalence of self-reported and sexually transmitted infections and HIV in the total sample was 10.7% and 2.7%, respectively. Factual knowledge and phobias regarding HIV/AIDS and self-efficacy were relatively high among the MSM. After controlling for age, education, marital status, and sexual identity, predictors of condom use at most recent anal sex included knowledge (OR = 1.25; p < 0.0001); self-efficacy (OR = 1.33; p = 0.02), additionally, having HIV testing (OR = 1.45; p = 0.02); and having a regular partner (OR = 0.53; p < 0.0001) were also positively associated with condom use.ConclusionThe intervention programs for MSM in Korea may need to take the idiosyncratic societal and cultural pressures of the region into consideration in order to reduce infection risk.
