Prevalence estimates of health risk behaviors of immigrant latino men who have sex with men

Purpose: Little is known about the health status of rural immigrant Latino men who have sex with men (MSM). These MSM comprise a subpopulation that tends to remain “hidden” from both researchers and practitioners. This study was designed to estimate the prevalence of tobacco, alcohol, and drug use, and sexual risk behaviors of Latino MSM living in rural North Carolina. Methods: A community‐based participatory research (CBPR) partnership used respondent‐driven sampling (RDS) to identify, recruit, and enroll Latino MSM to participate in an interviewer‐administered behavioral assessment. RDS‐weighted prevalence of risk behaviors was estimated using the RDS Analysis Tool. Data collection occurred in 2008. Results: A total of 190 Latino MSM was reached; the average age was 25.5 years and nearly 80% reported being from Mexico. Prevalence estimates of smoking everyday and past 30‐day heavy episodic drinking were 6.5% and 35.0%, respectively. Prevalence estimates of past 12‐month marijuana and cocaine use were 56.0% and 27.1%, respectively. Past 3‐month prevalence estimates of sex with at least one woman, multiple male partners, and inconsistent condom use were 21.2%, 88.9%, and 54.1%, respectively. Conclusions: Respondents had low rates of tobacco use and club drug use, and high rates of sexual risk behaviors. Although this study represents an initial step in documenting the health risk behaviors of immigrant Latino MSM who are part of a new trend in Latino immigration to the southeastern United States, a need exists for further research, including longitudinal studies to understand the trajectory of risk behavior among immigrant Latino MSM.

Abstract：

Objective To study the incidence and risk factors of HIV and syphilis seroconversion among men who have sex with men(MSM) in Beijing. Methods A total of 550 MSM were recruited on the basis of community and followed up after 6 and 12 months in Beijing.Each subject was investigated by only one investigator at one time to collect information on demographics and behaviors.Blood samples were collected to test HIV and syphilis seroconversion.ELISA was used for screening test,west blotting(WB) and Particle agglutination were used for confirmatory test. Results A total of 550 MSM investigated,among which 4.5% (25/550) were HIV-positive and 29.3% (161/550) were syphilis-positive.For 525 HIVnegative MSM,87.0% (457/525) retained during the 12-month investigation.Seroincidences for HIV and syphilis were 3.37/100 person-years (95% CI = 1.66-5.08) and 9.32/100 person-years (95% CI =5.87-12.77) respectively.HIV seroconversions for those who performed and did not perform rectal douching after homosexual anal intercourse in the past 3 months were 7.11/100 and 0.76/100 person-years respectively.Multivariate Cox regression analysis revealed that rectal douching after homosexual anal intercourse in the past 3 months(HR=9.23,95%CI =2.08-40.88) was significantly associated with HIV seroconversion.Syphilis seroconversions for those who met male sex partners in parks,public washrooms or bathhouses in the past 3 months were 41.77/100 and 7.97/100 person-years respectively.Syphilis seroconversions for those who performed and did not perform rectal douching after homosexual anal intercourse in the past 3 months were 16.17/100 and 4.92/100 person-years respectively.In the past 3 months,meeting male sex partners in parks,public washrooms or bathhouses (HR=4.67,95% CI = 1.77-12.34) and performing rectal douching after homosexual anal intercourse (HR = 3.09,95% CI=1.40-6.83) were significantly associated with syphilis seroconversion. Conclusion The seroconversions of HIV and syphilis during the follow-up visits in this MSM cohort study in Beijing were very serious,and that the associated factors for seroconversions were rectal douching after homosexual anal intercourse and meeting male sex partners in parks,public washrooms or bathhouses.     

Use of reality "female condoms" for anal sex by US men who have sex with men. HIVNET Vaccine Preparedness Study Protocol Team.

OBJECTIVES: This study assessed use of Reality "female condoms" for anal sex by HIV-seronegative men who have sex with men and are at high risk for HIV infection. METHODS: Self-administered questionnaires were completed by 2277 participants in a 6-city prospective cohort study. RESULTS: Of the 1084 (48%) men who had heard of using the female condom for anal sex, 145 (13%) reported using it in the prior 6 months. Users were at greater risk than nonusers: 47 receptive and 35 insertive users reported problems, including bleeding by the receptive partner (4). CONCLUSIONS: Redesign of the female condom could increase acceptability and use by men who have sex with men and could address possible safety concerns.     

High-risk behaviors among men who have sex with men in 6 US cities: baseline data from the EXPLORE Study

OBJECTIVES: We describe the prevalence of risk behaviors at baseline among men who have sex with men (MSM) who were enrolled in a randomized behavioral intervention trial conducted in 6 US cities. METHODS: Data analyses involved MSM who were negative for HIV antibodies and who reported having engaged in anal sex with 1 or more partners in the previous year. RESULTS: Among 4295 men, 48.0% and 54.9%, respectively, reported unprotected receptive and insertive anal sex in the previous 6 months. Unprotected sex was significantly more likely with 1 primary partner or multiple partners than with 1 nonprimary partner. Drug and alcohol use were significantly associated with unprotected anal sex. CONCLUSIONS: Our findings support the continued need for effective intervention strategies for MSM that address relationship status, serostatus of partners, and drug and alcohol use.     

Time-space sampling in minority communities: results with young Latino men who have sex with men

OBJECTIVES: This study addressed methodological issues influencing the feasibility of time-space sampling in HIV prevention studies targeting hard-to-reach populations of minority young men who have sex with men (MSM). METHODS: We conducted interviews with 400 men in 32 venues where young Latino MSM congregate in New York City. Response rates and demographic and sexual risk profiles are compared by venue type. RESULTS: More than 90% of the men approached were screened. Among eligible men, participation rates exceeded 82%. Participation was higher at special events and gay venues compared with nongay venues (P < .05). Young MSM in nongay venues were less likely to self-identify as gay (P < .01) or to report recent anal sex with a male (P < .10). Condom use did not vary by venue type but was lower with women than with men. If surveys had been limited to gay venues, about half of the young MSM surveyed in nongay venues would have been missed. CONCLUSIONS: Time-space sampling of a relatively "hidden" minority young MSM population can be successful across a range of venues. However, the benefits of greater outreach must be weighed against the costs incurred recruiting participants in nongay venues.

江苏省男男性行为者HIV新发感染状况及影响因素研究

目的了解江苏省男男性行为者（menwhohavesexwithmen,MSM）HIV新发感染状况及影响因素。方法2011年在江苏省8个地级市招募MSM,并进行问卷调查及实验室检测,应用BEDHIV一1IgG捕获酶免疫（BED-CEIA）法检出其中的新发感染者,以HIV阴性MSM为对照,采用多因素Logistic回归模型分析HIV新发感染的影响因素。结果共招募2432名MSM,HIV新发感染率为4．67％（95％CI：3．44％～5．89％）,HIV阴性和新发感染者之间在户籍省、文化程度、最近6个月是否与同性发生肛交、最近1次同性肛交是否使用安全套、最近6个月同性肛交安全套使用率及是否正在感染梅毒等变量上差异有统计学意义（均有P〈0．05）,多因素分析外省籍、文化程度低、最近1次同性肛交未使用安全套及正在感染梅毒是MSM人群HIV新发感染的主要危险因素。结论江苏省MSM人群中HIV新发感染率较高,提示HIV在该人群中正快速传播,必须加大防控力度;影响新发感染的主要因素仍为无保护性肛交及正在感染梅毒等。     

广西地区650 名男男性行为者对暴露前预防HIV感染接受意愿及其影响因素研究

目的 了解广西地区男男性行为者(MSM)对暴露前预防(PrEP)HIV感染的接受意愿及其影响因素.方法 采用滚雪球法招募650名MSM,利用自行设计的调查问卷一对一面访,了解MSM与艾滋病相关的高危行为、对PrEP的知晓情况及接受意愿.结果 假设PrEP使用的药物安全、有效且免费提供,有91.9%的MSM表示愿意服用药物.自述愿意服药的原因主要为可降低HⅣ感染的风险,不愿意服用药物的原因主要为担心药物的副作用和怀疑药物的效果.logistic回归分析显示,与接受PrEP意愿有关的因素为"是否通过朋友介绍性伴"(OR=6.21,P=0.020)、"是否有能力预防HIV感染"(OR=O.32,P=0.010)、"是否拒绝与不使用安全套的人发生性行为"(OR=0.34,P=0.010)、"是否建议朋友接受PrEP"(OR=39.32,P=0.000).结论 药物的安全性、有效性及费用可能是影响广西地区MSM接受PrEP的主要因素,免费提供安全、有效且副作用小的药物可能是推广PrEP的较好方式;以同伴教育的方式宣传PrEP可能会提高其接受意愿.

Abstract：

Objective To study the acceptability of pre-exposure prophylaxis (PrEP) to prevent the transmission of HIV among men who have sex with men (MSM) in Guangxi, China.Methods Snow-balling methods were used to recruit 650 MSM in Guangxi. Questionnaires and interview were administrated to these 650 men, using a self-designed questionnaire and face to face interviews to collect information on HIV-related risk behaviors, knowledge and acceptability of PrEP.effective, safe and free of charge', 597 (91.9%) of the 650 MSM claimed that they would accept it,who refused to use it, most of them said that were afraid of the side-effect and doubted on the effectiveness of PrEP. Data from logistic regression analysis showed that those who had found partners through friends (OR=6.21, P=0.020) and those who would advise his friend to use PrEP (OR=39.32, P=0.000) were more likely to accept PrEP. Those who thought they could protect themselves from HIV infection (OR=0.32, P=0.010) or not having sex with the ones who refused to use a condom (OR=0.34, P=0.010) were less likely to accept PrEP. Conclusion Effectiveness, safety and cost seemed to be the main influential factors related to the acceptability of PrEP. Peer education might improve the acceptability of PrEP.     

Serosorting sexual partners and risk for HIV among men who have sex with men

OBJECTIVE: The purpose of the current study was to assess whether men who have sex with men (MSM) who limit their unprotected anal sexual partners to those who are of the same HIV status (serosort) differ in their risk for HIV transmission than MSM who do not serosort. METHODS: Cross-sectional surveys administered at a large Gay Pride festival in June 2006 (80% response rate) were collected from MSM. Univariate and multivariate logistic regressions were used to identify predictors of serosorting. Analyses were conducted in 2006. RESULTS: Participants were self-identified as HIV-negative MSM (N=628); about one third of them engaged in serosorting (n=229). Men who serosort were more likely to believe that it offered protection against HIV transmission, perceived themselves as being at no relatively higher risk for HIV transmission, and had more unprotected anal intercourse partners. Over half the sample reported their frequency of HIV testing as yearly or less frequently; this finding did not differ between serosorters and nonserosorters. CONCLUSIONS: Men who identify as HIV-negative and serosort are no more likely to know their HIV status than men who do not serosort and are at higher risk for exposure to HIV. Interventions targeting MSM must address the limitations of serosorting.     

深圳市男男性行为者安全套使用影响因素分析

目的了解深圳地区男男性行为者（MSM）安全套使用情况,分析MSM肛交时安全套使用影响因素。方法应用同伴推动抽样（RDS）法进行抽样调查,收集MSM人群人口学和安全套使用等资料。结果共抽样调查351例MSM。最近半年,57．0％MSM肛交时每次均使用安全套,13．1％口交时每次均使用安全套,36．8％与女性发生性行为时每次均使用安全套,75．8％与男男性工作者发生性行为时每次均使用安全套。肛交时使用安全套受未婚、有女性性伴、HIV风险感知、性伴数≥5等因素影响。未婚、有女性性伴的MSM在最近半年肛交时安全套使用率高;HIV风险感知高、性伴数≥5的MSM在最近半年肛交时安全套使用率低。结论应有针对性地开展健康教育及行为干预,提高MSM安全套使用率。

A study of the STD/AIDS related attitudes and behaviors of men who have sex with men in Hong Kong

A random population based study was carried out to understand HIV-related attitudes and behaviors and self-reported sexually transmitted diseases (STDs) among men who have had sex with men (MSM) in Hong Kong. A special computerized telephone survey method was used and 85 MSM were identified (from a total sample of 2,074 men), 47.1% of whom had at least one male sex partner in the past 6 months. Among these 85 MSM, 29.4% had multiple partners and 37.5% had had anal sex in the last 6 months (67% of them were inconsistent condom users). MSM were more likely to have contracted at least one STD in the last 6 months (10.6%) and were less likely to perceive susceptibility for contracting HIV (62.4%) than those other respondents who visited a female sex worker (FSW) in the past 6 months (4.3% and 43%, respectively). About 45% of the MSM did not perceive condom use to be efficacious for HIV prevention (vs. 30% for male clients of FSW). The study is limited by its small number; however, it suggests that MSM in Hong Kong may be at high risk of contracting HIV. Prevention programs should attempt to change attitudes (e.g., perceived efficacy of condom use, perceived susceptibility, awareness of risk involved, etc.) as well as behaviors. The feasibility for establishing a behavioral surveillance system for this population was demonstrated.
