Bisexual Behaviors, HIV Knowledge, and Stigmatizing/Discriminatory Attitudes among Men Who Have Sex with Men

Utilization of post-exposure prophylaxis potentially contributed to the changes of risk behaviors among men who have sex with men in China

Background

The HIV infection status among men who have sex with men (MSM) in China is a cause for concern. Post-exposure prophylaxis (PEP) serves as a highly effective biomedical preventive measure against HIV infection. Substantial evidence has established an association between PEP utilization and risk behaviors among MSM, but whether the utilization of PEP has an impact on risk behaviors remains unknown. This study sought to elucidate the impact of PEP usage on risk behaviors among MSM and provide recommendations for developing targeted HIV prevention programs.

Methods

A cohort study was conducted in Qingdao, China, from April 2021 to January 2022. Participants were enlisted by volunteers from community-based organizations through a snowball sampling method. Face-to-face interviews were conducted to collect sociodemographic and behavioral information of participants. The study encompassed a retrospective investigation, baseline survey, and follow-up survey, representing periods before, during, and after PEP usage, respectively. Generalized estimating equations, fitting a Poisson regression model, were applied to scrutinize changes in risk behaviors of MSM during and after PEP usage, in comparison to before PEP usage.

Results

A total of 341 MSM were recruited in the cohort study, with 179 individuals completing the follow-up survey. In comparison to before PEP usage, there was a significant increase in the proportion of Rush Popper usage (17.6% vs. 23.8% vs. 29.6%) and commercial sexual partners (10.9% vs. 17.6% vs. 21.8%) among MSM during and after PEP usage. Before PEP usage, 88.7% of MSM reported having ≥3 temporary sexual partners in the last 6 months. This proportion exhibited no significant change during PEP usage (91.8%), but it significantly increased to 97.8% after PEP usage (P < 0.05). Notably, there was a significant decrease in group sex during and after PEP usage compared to before PEP usage (30.8% vs. 21.4% vs. 21.2%).

Conclusion

The utilization of PEP may impact risk behaviors among MSM, potentially leading to increased Rush Popper usage, temporary sexual partners, and commercial sexual partners after PEP usage, accompanied by a decrease in group sex. Further research is imperative to elucidate the impact of PEP utilization on MSM and develop targeted HIV prevention programs.

Behavioral verification and risk factors of HIV cross-population transmission in China: analysis of national surveillance data 1989-2022

INTRODUCTION

The dynamic HIV/AIDS epidemic significantly impacts China, particularly affecting injection drug users (IDUs), former plasma donors (FPDs), men who have sex with men (MSM), and those engaging in high-risk heterosexual behavior (HRHB). This study specifically focuses on identifying the risk factors and influences that drive the spread of HIV among these population groups by performing a comprehensive analysis of contact histories of individuals diagnosed with HIV.

METHODS

Data for this research were gathered from China's HIV/AIDS Comprehensive Response Information Management System (CRIMS). Contact histories were described using bar and venn diagram. Trend in engaging in HBRB among MSM were identify potential change using the Cochran-Armitage test. Logistic regression was employed to analyze the factors influencing HBRB in MSM.

RESULTS

From 1989 through to 2022, a total of 1,457,218 individuals aged 15 years or older in China, who reported being infected with HIV, indicated they had one or more types of contact histories including injecting drug use, male homosexual behavior, commercial plasma donation, and high-risk heterosexual behavior. Among these, 97.0% reported a single type of contact history, while 3.0% reported having multiple contact histories. Of those with multiple contact histories, 98.0% (42,258 individuals) had engaged in HRHB. Among all HIV-infected IDUs, MSM, and FPDs, their respective proportions of engagement in HRHB were 11.8%, 5.7% and 6.2%. Prior to 2012, most were reported to be IDUs; however, subsequent to this, most reported being MSM. Factors that heightened the risk of engaging in HRHB among HIV-infected MSM included being of age between 25-34 years [adjusted odds ratio (AOR) = 1.29] or 35-44 years (AOR = 1.22), marital status such as being married (AOR = 1.23) or being divorced/widowed (AOR = 1.17), belonging to an ethnic minority (AOR = 1.29), receiving diagnosis in hospitals (AOR = 1.81), residing in rural areas (AOR = 1.12), among others. However, the risk of HRHB decreased when age ≥ 55 years (55-64 years: AOR = 0.82; ≥ 65 years: AOR = 0.64).

CONCLUSION

The potential for HIV transmission among diverse populations is substantial. As such, it is imperative that strategies are implemented to mitigate the propagation of HIV to the general populace via heterosexual intercourse.

HIV Prevalence and Risk Factors Among Young Men Who Have Sex With Men in Southwest China: Cross-sectional Questionnaire Study

BACKGROUND

Previous studies showed an increase in HIV prevalence among young men who have sex with men aged 25 years or younger in China.

OBJECTIVE

This study aimed to assess HIV prevalence and associated factors among young men who have sex with men in the Guangxi Zhuang Autonomous Region.

METHODS

This study was conducted in 4 cities (Guilin, Liuzhou, Beihai, and Nanning) in the Guangxi Zhuang Autonomous Region between June 2014 and May 2016. Participants were reached through web-based and site recruitment approaches. Laboratory tests were performed to detect HIV and syphilis infections. A self-administered questionnaire was used to collect data from 632 eligible young men who have sex with men.

RESULTS

The prevalence of HIV and syphilis was 9.3% (59/632) and 11.4% (72/632), respectively. Multivariable logistic analysis showed that ethnic minority (adjusted odds ratio [AOR] for Han Chinese vs other minorities 0.28, 95% CI 0.11-0.71, P=.007), receptive sexual positioning in the past 6 months (AOR 2.94, 95% CI 1.32-6.53, P=.008), current syphilis infection (AOR for individuals without vs those with infection 0.38, 95% CI 0.19-0.75, P=.005), inconsistent condom use in the past 6 months (AOR 1.91, 95% CI 1.06-3.45, P=.03), and psychotropic drug use before last anal intercourse (AOR 16.70, 95% CI 2.34-119.18, P=.005) were independently associated with HIV infection.

CONCLUSIONS

There is an urgent need to scale up HIV and syphilis interventions in young men who have sex with men. Some subgroups might need specific attention for HIV prevention, including ethnic minority men, individuals with a history of sexually transmitted infections, and individuals who have been engaging in receptive anal sex.

User Experience and Usability of Neumorphism and Gamification User Interface Designs in an HIV Self-Test Referral Program for Men Who Have Sex With Men: Prospective Open-Label Parallel-Group Randomized Controlled Trial

Background

Digital interventions have been applied for promoting HIV prevention and care among men who have sex with men (MSM). As user interface (UI) design plays a role in determining usability and user experience (UX), the intervention outcome could be affected.

Objective

In this study, we hypothesized that 2 UI design styles, namely gamification and neumorphism, could impact usability and be differentially preferred by distinct groups of MSM.

Methods

A prospective parallel-group open-label randomized controlled trial was conducted in Hong Kong. Eligible participants were adult MSM recruited by the research team or referred by enrolled participants, who followed instructions for performing an HIV self-test and promoted its use within their social network. Participants were randomized in a 1:1 ratio into either a gamification or neumorphism arm, with primarily visual differences in the UI only. The primary outcome was usability measured by the System Usability Scale (SUS) between the 2 arms. Distinct characteristics of promoters in the 2 arms who gave an SUS score of 80 or above were identified.

Results

Of 463 MSM registered in the study, 232 and 231 were randomized to the gamification and neumorphism arms, respectively. Excluding those who did not request a self-test kit, data from 218 and 216 participants in the gamification and neumorphism arms, respectively, were analyzed (totally 434 participants). With a median SUS score of 80 overall, participants in the neumorphism arm gave a higher score (P<.001), with a higher proportion giving a promoter-level SUS score (P=.002). Promoters used social media for sex networking (P=.02), used pre-exposure prophylaxis in the preceding year (P=.006), had higher satisfaction in UI design (P<.001), and had made a self-test referral (P=.04). In general, higher usability was recorded among participants who were confident in performing the HIV self-test (P<.001), and this was associated with a promoter-level SUS score in both arms. While no other personal characteristics were associated with promoters in the neumorphism arm, those in the gamification arm had higher HIV-related knowledge (P=.01), preferred a specific partner body image type (P=.03), and progressed toward peer referral by completing online training (P=.04).

Conclusions

Both gamified and neumorphic UI designs were well-accepted by MSM. UX and satisfaction of UI were both crucial in influencing the willingness of MSM to promote the application by referring their peers in the community to participate. The simplistic visual design of neumorphism conferred a more general acceptance in the community, whereas gamification was preferred in certain MSM subcommunities. Appropriate UI/UX design should be considered when developing digital interventions targeting the MSM community.

User Preferences for an mHealth Approach to Support HIV Self-Testing and Linkage to HIV Prevention or Care Services for MSM in China

This research qualitatively explored user preferences for an app-based mHealth approach to support HIV self-testing and linkage to HIV prevention or care services developed for men who have sex with men (MSM) in China. We conducted 12 online focus group discussions with MSM participants (N = 48) about their preferences for using an app to meet their HIV self-testing and service linkage needs. Data were examined using thematic analysis. Participants specified four domains to align program delivery with their preferences for app-based intervention: (1) expanding HIV prevention/antiretroviral therapy concepts beyond basic knowledge; (2) enhancing the style and presentation of app-based messages; (3) incorporating interactive and dynamic app-engagement features; and (4) creating a "one station" app that covers the continuum of HIV services. Given the changing landscapes of HIV knowledge and community/user preferences for app-based interaction, findings underscore how engagement with end-user participants is essential to optimize mHealth interventions for HIV.

Factors associated with low knowledge about sexually transmitted infections in subnormal agglomerate, in the Brazilian Amazon

BACKGROUND

Populations living in subnormal agglomerates in urban areas are more vulnerable to infections, including sexually transmitted infections (STIs). In these groups, inadequate knowledge about sexually transmitted infections can further increase the risk of contracting STIs.

AIM

We investigated the factors associated with low knowledge about STIs in a peripheral population in the Brazilian Amazon.

METHODS

This cross-sectional study was conducted in Belém, in the Amazon region that has a high percentage of subnormal agglomerates in an urban area and a high incidence of STIs. Random sampling was adopted which resulted in a sample of 320 participants. To assess knowledge about STIs, the self-administered Sexually Transmitted Disease Knowledge Questionnaire was used. To assess aspects of vulnerability, a questionnaire was constructed which is linked to individual, social, and programmatic factors. The chi-square test, G test, and ordinal regression analyses were all performed.

FINDINGS

The sample of this study was composed of 320 participants. The mean age of the participants was 46.09 years. 37.5% (120), 50.6% (162), and 11.9% (38) showed low, medium, and high knowledge, respectively. Multiple analysis revealed that the factors associated with higher chance of having smaller knowledge about sexually transmitted infections were single/separated/divorced/widow(er) marital status (AOR: 1.80, CI: 1.15-2.84, P = 0.01); income equal to or less than one minimum wage (1.98, CI: 1.21-3.17, P = 0.00); equal to or over than 52 years old (AOR: 1.99, CI: 1.25-3.17, P = 0.00); lack of guidance by a health professional (AOR: 1.59, CI: 1.01-2.51, P = 0.04). Our results show that this community suffer from suboptimal levels of knowledge on STIs, which are linked to individual, social, and programmatic factors. Characterising the risk and vulnerabilities factors allows for carrying out appropriate interventions for populations living in subnormal agglomerates in urban area.

Methodologies of Stigma-Related Research Amongst Men Who Have Sex With Men (MSM) and Transgender People in Asia and the Pacific Low/Middle Income Countries (LMICs): A Scoping Review

Much stigma-related research focuses on marginalized populations, including men who have sex with men (MSM) and transgender people. The importance of research in this area is widely recognized, however methodologies and measures vary between studies. This scoping review will collate existing information about how stigma-related research has been conducted in low/middle income countries (LMICs) within the Asia Pacific region, and will compare research designs, sampling frameworks, and measures. Strengths and limitations of these studies will inform recommendations for future stigma-related health research. A methodological framework for scoping studies was applied. Searches of Psych INFO, Scopus, ProQuest, Global Health and PubMed were used to identify articles. Stigma-related research amongst MSM and transgender communities, published between 2010 and 2019 in LMICs within the Asia Pacific region were included. A total of 129 articles based on 123 different studies were included. Of the 129 articles 51.19% (n = 66) were quantitative; 44.96% (n = 57) were qualitative and 3.88% (n = 5) were mixed methods studies. The majority of studies (n = 57; 86.36%) implemented a cross sectional survey. In-depth interviews (n = 20, 34.48%) were also common. Only 3.88% of studies utilized mixed-methods design. Non-probabilistic and probabilistic sampling methods were employed in 99.22 and 0.78% of studies respectively. The most common measures used in quantitative studies were the Center for Epidemiological Study on Depression (CES-D) (n = 18) and the Self Stigma Scale (SSS) (n = 6). Strengths and limitations proposed by researchers included in this review are summarized as lesson learnt and best practices in stigma-related research.

The Holistic Health Status of Chinese Homosexual and Bisexual Adults: A Scoping Review

Background: Same-sex marriage is currently not legalized in China, despite the considerably large number of homosexual and bisexual Chinese populations. At the same time, their holistic health status remains unclear. This is the first scoping review conducted to comprehensively examine all the available literature and map existing evidence on the holistic health of homosexual and bisexual Chinese. Methods: This scoping review used the framework of Arksey and O'Malley and followed the Preferred Reporting Items for Systematic Review and Meta-Analysis extension for scoping reviews (PRISMA-ScR). A comprehensive search strategy was carried out across 20 English (EN) and Chinese (both traditional and simplified) electronic databases from January 1, 2001, to May 31, 2020. Two reviewers conducted the reference screening and study selection independently and consulted a third senior reviewer whenever a consensus must be achieved. Data extraction was conducted using a structured data form based on the Cochrane template, after which a narrative synthesis of the findings was performed. Results: A total of 2,879 references were included in the final analysis, with 2,478 research articles, 167 reviews, and 234 theses. Regarding the study populations, the vast majority of studies centered on men only (96.46%), especially men who have sex with men (MSM). Only 1.32% of the studies targeted female sexual minorities. The geographical distribution of all research sites was uneven, with most of them being conducted in mainland China (95.96%), followed by Hong Kong (2.05%), Taiwan (2.02%), and Macau (0.06%). Regarding the specific study focus in terms of the health domain, around half of the studies (45.93%) focused on sexual health only, and an additional quarter of the studies (24.15%) investigated both sexual health and social well-being. Meanwhile, the studies focusing on mental health only accounted for approximately 15% of the total. Conclusions: This scoping review revealed that previous research focused more on male than female sexual minorities, on disease-centered surveys than person-centered interventions, and investigations on negative health conditions than positive health promotion. Therefore, investigations centered on the female sexual minorities and corresponding person-centered interventions are highly needed. Review Registration: The protocol of this review has been registered within Open Science Framework (https://osf.io/82r7z) on April 27, 2020.

Relationship between sexual sensation seeking and condom use among young men who have sex with men in China: testing a moderated mediation model

The present study incorporated a moderated mediation model to explore the role of attitude towards condom use in mediating the link between sexual sensation seeking (SSS) and condom use and whether this indirect link was modified by HIV-related knowledge among Chinese YMSM. Survey data were collected from a cross-sectional study conducted in Wuhan, China and 373 YMSM were recruited. The mediation and moderated mediation modelling analyses were performed with the software SPSS PROCESS macro. Mediation analysis indicated that attitude towards condom use partly mediated the link between SSS and condom use (indict effect = -0.158, P < 0.001). Moderation analysis found HIV-related knowledge acted as a moderator in the relationship between SSS and attitude towards condom use (interact effect = 0.089, P = 0.001). Final moderated mediation analysis demonstrated that the indirect effect from SSS to condom use through attitude towards condom use was moderated by HIV-related knowledge, that is the interaction between HIV-related knowledge and SSS was positively associated with attitude towards condom use (β = 0.101, P < 0.001). Therefore, increased YMSM-specific HIV-related knowledge education programs need to be conducted. Further longitudinal research is required to verify the findings of this study.

Seizing opportunities for intervention: Changing HIV-related knowledge among men who have sex with men and transgender women attending trusted community centers in Nigeria

BACKGROUND

Knowledge of HIV risk factors and reduction strategies is essential for prevention in key populations such as men who have sex with men (MSM) and transgender women (TGW). We evaluated factors associated with HIV-related knowledge among MSM and TGW and the impact of engagement in care at trusted community health centers in Nigeria.

METHODS

The TRUST/RV368 cohort recruited MSM and TGW in Lagos and Abuja, Nigeria via respondent driven sampling. During study visits every three months, participants underwent structured interviews to collect behavioral data, received HIV education, and were provided free condoms and condom compatible lubricants. Five HIV-related knowledge questions were asked at enrollment and repeated after 9 and 15 months. The mean number of correct responses was calculated for each visit with 95% confidence intervals (CIs). Multivariable Poisson regression was used to calculate adjusted risk ratios and CIs for factors associated with answering more knowledge questions correctly.

RESULTS

From March 2013 to April 2018, 2122 persons assigned male sex at birth were enrolled, including 234 TGW (11.2%). The mean number of correct responses at enrollment was 2.36 (95% CI: 2.31-2.41) and increased to 2.95 (95% CI: 2.86-3.04) and 3.06 (95% CI: 2.97-3.16) after 9 and 15 months in the study, respectively. Among 534 participants who completed all three HIV-related knowledge assessments, mean number of correct responses rose from 2.70 (95% CI: 2.60-2.80) to 3.02 (95% CI: 2.93-3.13) and then 3.06 (95% CI: 2.96-3.16). Factors associated with increased overall HIV-related knowledge included longer duration of study participation, HIV seropositivity, higher education level, and more frequent internet use.

CONCLUSIONS

There was suboptimal HIV-related knowledge among Nigerian MSM and TGW at that improved modestly with engagement in care. These data demonstrate unmet HIV education needs among Nigerian MSM and TGW and provide insights into modalities that could be used to address these needs.

HIV/AIDS knowledge among MSM in Brazil: a challenge for public policies

INTRODUCTION

High level of HIV/AIDS knowledge is required for an effective adoption of preventive strategies.

OBJECTIVE

To assess HIV/AIDS knowledge among men who have sex with men (MSM) in 12 Brazilian cities.

METHODS

Respondent-Driven Sampling method was used for recruitment. HIV/AIDS knowledge was assessed by Item Response Theory. Difficulty and discrimination parameters were estimated, and the knowledge score was categorized in three levels: high, medium, and low. Logistic regression was used for analysis.

RESULTS

Among 4,176 MSM, the proportion of high level of knowledge was 23.7%. The following variables were positively associated with high knowledge (p < 0.05): age 25+ years old, 12+ years of schooling, white skin color, having health insurance, having suffered discrimination due to sexual orientation, having had a syphilis test, and having received educational material in the previous 12 months. Exchanging sex for money was negatively associated.

CONCLUSIONS

The proportion of only 23.7% of high HIV/AIDS knowledge was low. We should note that the only potential source of knowledge acquisition associated with high level of knowledge was receiving educational materials. Our study indicates the need for expansion of public prevention policies focused on MSM and with more effective communication strategies, including the development of knowledge that involves motivation and abilities for a safer behavior.

Out of the Closet, Into the Clinic: Opportunities for Expanding Men Who Have Sex With Men-Competent Services in China

BACKGROUND

Despite the high human immunodeficiency virus (HIV) burden among men who have sex with men (MSM), there is little research on health services provided to MSM in China and other low- and middle-income countries. Discrimination and inadequate services may discourage MSM from seeking health care services. This study examined essential services provided to MSM and health care discrimination among MSM in China.

METHODS

A nationwide cross-sectional online survey was conducted among MSM who saw a physician in the last 24 months in China. The survey included items on sociodemographic information, HIV testing, experiences from the last physician encounter, and history of perceived health care discrimination. We defined MSM-competent physicians as physicians who asked their patient about having sex with other men, asked about anal sex, and either asked about or recommended HIV testing at the most recent visit.

RESULTS

Among the 503 participants, 35.0% (176/503) saw an MSM-competent physician. In multivariate analyses, respondents who saw an MSM-competent physician were more likely to be younger (adjusted odds ratio [AOR], 0.87; 95% confidence interval [CI], 0.81-0.94), have a primary care physician (AOR, 3.24; 95% CI, 1.85-5.67), and be living with HIV (AOR, 2.01; 95% CI, 1.13-3.56). 61.2% (308/503) of MSM had ever experienced health care discrimination.

CONCLUSIONS

Our data suggest that there is variability in the extent to which physicians are meeting the needs of MSM in China. There is an urgent need to evaluate and expand MSM-competent services in China.

Assessing consistent condom use among migrant men who have sex with men in Shanghai, China: validation of an information-motivation-behavioural skills model

BACKGROUND

In China, high prevalence of risky sexual behaviours and inequity in health services lead to situations in which migrant men who have sex with men face higher risk of contracting the human immunodeficiency virus. Consistent condom use is a primary means of preventing HIV infection during anal sex among MSM. This study aimed to apply the information-motivation-behavioural skills model to examine the predictors of consistent condom use among migrant MSM in Shanghai, and tested the associations between model constructs.

METHODS

A cross-sectional study was conducted among 412 migrant MSM in Shanghai. Data on HIV-related information, motivation, behavioural skills, and behaviours were collected via structured questionnaires. A structural equation model was used to assess the IMB model.

RESULTS

Of the 412 participants, 4.4% reported HIV-positive status, and prevalence of consistent condom use in the previous 6 months was 44.9%. A restricted IMB model provided an acceptable fit to the data. Behavioural skills were found to directly predict consistent condom use (β = 0.629, P < 0.01). Neither information nor motivation could directly predict consistent condom use (P > 0.05), but motivation predicted it indirectly and was mediated by behavioural skills.

CONCLUSION

The prevalence of consistent condom use was found to be relatively low among migrant MSM in Shanghai. The restricted IMB model was found to be a good predictor of consistent condom use among them. The results of this study indicate that intervention strategies for safer sexual behaviour should not only include information dissemination, but also emphasize motivation and behavioural skills among this population.

Socio-demographic Characteristics, Sexual and Test-Seeking Behaviours Amongst Men Who have Sex with Both Men and Women: Results from a Bio-behavioural Survey in 13 European Cities

Within the MSM population, men who have sex with both men and women (MSMW) are identified as a high-risk group both worldwide and in Europe. In a multi-centred bio-behavioural cross-sectional study, we aimed to assess the relationship(s) between socio-demographic factors, stigma, sexual behavioural patterns, test seeking behaviour and sero-status amongst MSMW. A multi-level analysis was conducted to identify factors associated with being MSMW versus Men who have Sex with Men Only (MSMO). A total of 4901 MSM were enrolled across the 13 study sites. Participants were categorised as MSMW in the 12.64% of the cases. Factors such as educational status, perceived homonegativity, testing facilities knowledge and HIV testing lifetime seem to be relevant factors when characterising the MSMW group. The results highlight the vulnerability of MSMW and the wide spectrum of risky behavioural and psycho-social patterns, particularly in terms of HIV testing, 'outness', and perceived stigma.

Associated factors of self-reported psychopathology and health related quality of life among men who have sex with men (MSM) with HIV/AIDS in Dalian, China: a pilot study

Background

Despite the availability of Anti-Retroviral Therapy (ART), the health-related quality of life (HRQoL) among HIV-positive men who have sex with men (HIVMSM) in China remains poor. This study aimed to explore the relationship between self-reported psychopathology and HRQoL among HIVMSM in Dalian, China.

Methods

A cross-sectional study was conducted in 112 HIVMSM. Symptom check list 90 (SCL 90): a measure of psychopathology and World Health Organization quality of life in HIV infection (WHOQOL-HIV-Bref): a measure of HRQoL were used. Correlation and multiple regression analysis were employed to explore the association between self-reported psychopathology and HRQoL in HIVMSM.

Results

Out of the total 112 HIVMSM cases, 9 (8 %) cases were homosexuals and 103 (92 %) ones were bisexuals. The participants who had low family income (P = 0.001), perceived discrimination (P = 0.001) and lack of regular attendance in medical follow-ups (P = 0.014) reported poorer HRQoL than their counterparts. Somatization, obsession, depression, phobia and overall SCL 90 scores in self-reported psycholpathology had a negative impact on the domains of HRQoL among HIVMSM.

Conclusions

Total quality of life was predicted by family income, perceived discrimination, and medical follow-up attendance. Self-reported psychopathology was negatively correlated with HRQoL in HIVMSM. The Strategies that target MSM focusing on linking and engaging HIV-positive patients in medical care is the key step to improve their HRQoL. More emphasis is needed on the newly diagnosed HIVMSM in Dalian in order to develop a more targeted intervention to prevent perceived discrimination and lack of proper medical follow-up services.

Trial registration

The trial registration number does not require for this manuscript. The study is cross-sectional design that do not involve intervention at all, it is not a clinical trial.

Associations between sexual sensation seeking and AIDS-related knowledge, attitudes and behaviors among young men who have sex with men in China

Young men who have sex with men (YMSM) have become high risk groups for HIV infection in China. Recent researches suggest that sexual sensation seeking is significantly associated with AIDS-related knowledge, attitudes and behaviors, but the relationship is not clear in the field of YMSM in China. The present study aimed to evaluate the relationship between sexual sensation seeking and AIDS-related knowledge, attitudes, and behaviors among YMSM in China. A cross-sectional study was conducted in Wuhan, China from May to November 2013. 403 YMSM were recruited and 373 of them completed the questionnaire. Regression analyses indicated that YMSM with high sexual sensation seeking score are more likely to have low awareness of knowledge and negative attitude about condom use, as well as more risky sexual behaviors.
