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 chlamydia and gonorrhoea among a population of men who have sex with men

OBJECTIVES: Few data are available on the prevalence of sexually transmitted diseases (STDs) in men who have sex with men (MSM), making it difficult to develop STD screening guidelines for this population. The objective of the study was to determine the prevalence of urethral infections caused by Chlamydia trachomatis and Neisseria gonorrhoeae within a large, community based population of MSM, and to assess the feasibility of rectal screening in this population. METHODS: This was a cross sectional study of 566 MSM, who were predominantly middle aged, white, asymptomatic, and engaged in sex with multiple partners. All provided a urine sample to screen for chlamydial and gonorrhoea infections using a PCR assay; rectal screening was performed on 48 participants. RESULTS: Urethral C. trachomatis infections were detected in 1/566 participants (prevalence 0.2%, 95% CI 0.004% to 1.0%), and rectal C. trachomatis infections were detected in 2/48 men (prevalence 4.2%, 95% CI 0.5% to 14.2%). No gonorrhoea infections were detected, and none of the 117 HIV positive men had either infection. CONCLUSIONS: Chlamydial and gonorrhoea infections were uncommon in this sample of MSM, even among those with multiple sexual partners or HIV infection. These data call into question recommendations to screen all MSM based on their individual sexual behaviours or HIV. Additional data are needed on the prevalence of these infections in MSM from different settings.     

2010-2019年云南省玉溪市男男性行为者艾滋病哨点监测结果及知行分离影响因素分析

目的了解2010-2019年云南省玉溪市MSM人群HIV、梅毒和HCV感染状况及艾滋病知晓情况并分析知行分离的影响因素。方法根据《全国艾滋病哨点监测方案》的要求,以每年4-7月为监测期,采用横断面调查法对玉溪市MSM人群的人口学特征、艾滋病知识知晓情况、行为学和接受艾滋病干预服务等情况进行连续监测,应用Logistic回归分析分析MSM人群知行分离的相关影响因素。结果2010-2019年玉溪市监测MSM共3765人次,98.94%(3725/3765)知晓艾滋病基本知识,25.42%(946/3721)存在知行分离。79.18%(2586/3266)的MSM最近6个月与同性肛交时坚持使用安全套,历年坚持使用安全套比例呈上升趋势(B=3.384,P=0.011)。HIV、梅毒和HCV感染率分别为4.54%(95%CI:3.88%~5.21%)、3.45%(95%CI:2.87%~4.04%)和0.64%(95%CI:0.38%~0.89%)。多因素Logistic回归分析显示,年龄越大、户籍为外省、文化程度为初中及以下、最近6个月与异性发生过性行为、最近1年患有性病和HIV抗体阳性者是知行分离的危险因素,而最近1年接受过艾滋病干预服务是保护因素。结论2010-2019年玉溪市MSM人群HIV感染率基本平稳,但坚持使用安全套的比例不高,存在知行分离现象,应提供精准干预,促进MSM坚持使用安全套。     

Prevalence of syphilis and HIV infections among men who have sex with men from different settings in Shenzhen, China: implications for HIV/STD surveillance

HIV/STD surveillance system data are important for developing prevention and control programmes for men who have sex with men (MSM), now a core group in Chinese HIV/STD surveillance activities. MSM were recruited from different settings in Shenzhen and were tested for HIV and syphilis. A substantial prevalence of HIV and syphilis infections was found in this population. However, risk behaviours and sociodemographic characteristics varied greatly among MSM recruited from the different settings (gay sauna, gay bar and MSM clinic), suggesting that carefully considering and selecting appropriate settings to represent the MSM population is critical for developing HIV and STD surveillance and prevention programmes.     

Prevalence and risk behaviors of Hong Kong males who seek cross-border same-sex partners in mainland China

BACKGROUND: Little is known about cross-border sex-networking behaviors among men who have sex with men (MSM) GOAL: The goal of this study was to determine the prevalence of cross-border sex-networking in mainland China among MSM in Hong Kong and the associated risk behaviors STUDY: A telephone survey was conducted. A total of 15,230 Hong Kong Chinese men aged 18 to 60 participated in the study. RESULTS: Of the 283 MSM engaged in some MSM behaviors in the last 6 months, 15.2% had engaged in sexual activity with a man in mainland China in the 6 months before the survey. These "cross-border MSM" were more likely than others to have practiced risk behaviors such as having patronized male commercial sex workers, having contracted a sexually transmitted disease (STD), having had > or = 3 MSM partners, and having higher prevalence of HIV testing in the last 6 months (adjusted odds ratio, 3.32-43.83). CONCLUSIONS: There is an urgent need for a regional approach to HIV/STD prevention for MSM in southern China.     

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.     

Men who have sex with men: perceptions about sexual risk, HIV and sexually transmitted disease testing, and provider communication

OBJECTIVES: This study was designed to gain a deeper understanding of the barriers and facilitators related to sexually transmitted diseases (STDs) and HIV screening among at-risk Boston men who have sex with men (MSM). STUDY DESIGN: The cohort was recruited by a modified respondent-driven sampling technique and used one-on-one semistructured interviews and a quantitative survey to examine participants' understanding of STDs and HIV, perceptions of risk for disease, reasons for getting (or not getting) tested, and experiences with testing. RESULTS: The study found that although most of the MSM knew the signs and symptoms of HIV, they were less familiar with STDs. MSM were most likely to be screened if they had symptoms or were told by a partner of a recent exposure. However, many barriers to STD/HIV screening among MSM still exist, including lack of awareness of symptoms, misperceptions about the ways STDs are transmitted, and perceived impediments from the healthcare system, including misgivings about provider sensitivity. CONCLUSIONS: To decrease current increases in HIV/STDs among MSM, new strategies that include community and provider education are needed.
