Abstract
BACKGROUND Observational studies suggest that voluntary medical male circumcision (VMMC) may lower HIV risk among men who have sex with men (MSM). A randomized controlled trial (RCT) is needed to confirm this. OBJECTIVE To assess the efficacy of VMMC in preventing incident HIV infection among MSM. DESIGN An RCT with up to 12 months of follow-up. (Chinese Clinical Trial Registry: ChiCTR2000039436). SETTING 8 cities in China. PARTICIPANTS Uncircumcised, HIV-seronegative men aged 18 to 49 years who self-reported predominantly practicing insertive anal intercourse and had 2 or more male sex partners in the past 6 months. INTERVENTION VMMC. MEASUREMENTS Rapid testing for HIV was done at baseline and at 3, 6, 9, and 12 months. Behavioral questionnaires and other tests for sexually transmitted infections were done at baseline, 6 months, and 12 months. The primary outcome was HIV seroconversion using an intention-to-treat analysis. RESULTS The study enrolled 124 men in the intervention group and 123 in the control group, who contributed 120.7 and 123.1 person-years of observation, respectively. There were 0 seroconversions in the intervention group (0 infections [95% CI, 0.0 to 3.1 infections] per 100 person-years) and 5 seroconversions in the control group (4.1 infections [CI, 1.3 to 9.5 infections] per 100 person-years). The HIV hazard ratio was 0.09 (CI, 0.00 to 0.81; P = 0.029), and the HIV incidence was lower in the intervention group (log-rank P = 0.025). The incidence rates of syphilis, herpes simplex virus type 2, and penile human papillomavirus were not statistically significantly different between the 2 groups. There was no evidence of HIV risk compensation. LIMITATION Few HIV seroconversions and limited follow-up period. CONCLUSION Among MSM who predominantly practice insertive anal intercourse, VMMC is efficacious in preventing incident HIV infection; MSM should be included in VMMC guidelines. PRIMARY FUNDING SOURCE The National Science and Technology Major Project of China.

Abstract
There are certain demographic characteristics that may serve as risk factors for exposure to a contact allergen. Volatile alkyl nitrites, colloquially known as "poppers," are commonly inhaled by men who have sex with men (MSM) for their psychoactive and muscle-relaxing effects. They have been reported to cause either allergic contact Dermatitis® (ACD) or irritant contact Dermatitis® (ICD), termed "poppers Dermatitis®." We searched PubMed, Embase, and Web of Science to understand the patient population, clinical presentation, diagnosis, and clinical course of poppers Dermatitis®. Our search returned 13 articles detailing 18 patients total. Most patient cases were male (n = 13/15; 87%), of whom 5 were MSM. The reports on the remaining 8 men did not disclose their sexual behaviors. The chemicals deemed responsible for adverse cutaneous side effects included amyl nitrite (6/18; 33%), butyl nitrite (3/18; 167%), isobutyl nitrite (2/18; 11%), and an unspecified alkyl nitrite (7/18, 39%). The most common diagnosis was ICD (10/18; 56%). Only 3 patients underwent alkyl nitrite patch testing, with 2 testing positive for ACD. The most commonly involved anatomic sites were perinasal (13/18; 72%) and perioral regions (10/18; 56%). Rash morphology has been described as yellow crusting, impetigo-like, eczematous, vesicular, edematous, and erythematous. Ulceration can occur with direct skin contact to concentrated nitrite solution. Poppers Dermatitis® was often self-limited with complete resolution. Dermatologists should consider poppers Dermatitis® in those presenting with a characteristic midfacial rash, especially in MSM.

Homoprejudiced Violence Experiences and High-Risk Sexual Behaviors among Chinese Men Who Have Sex with Men: Depression Severity and Recreational Drug Usage as Potential Mediators. ARCHIVES OF SEXUAL BEHAVIOR 2024; 53:1265-1276. [PMID: 38172350 DOI: 10.1007/s10508-023-02775-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 11/29/2023] [Accepted: 11/29/2023] [Indexed: 01/05/2024]
Abstract
Homoprejudiced violence is a type of aggression against an individual or a community based on their actual or perceived sexual orientation. It may be linked to risks of acquiring HIV/STI via psychosocial variables. This study explored the association between homoprejudiced violence experiences and high-risk sexual behaviors, and potential psychosocial mediators. Using cross-sectional survey data collected in China through Blued among men who have sex with men (MSM) in January 2021, this study conducted multiple mediation analyses. Standard instruments were used to collect data on depressive symptoms in the last two weeks (PHQ-9), recreational drug usage in the last three months, and ever experiencing homoprejudiced violence (12-item survey instrument). Dependent variables were having condomless anal sex and having three or more sexual partners in the last three months. Among 1828 MSM, nearly half (847, 46%) had experienced homoprejudiced violence. Twenty-three percent (427) reached a score that suggested moderate or severe depression and 35% (644) had used recreational drugs. In the last three months, 40% (731) had condomless anal sex and 34% (626) had three or more sexual partners. The indirect mediational coefficients through depression on condomless anal sex and multiple sexual partners were 0.04 (95% CI: [0.02, 0.07]) and 0.02 (95% CI: [0.001, 0.05]), respectively. The indirect mediational coefficient of homoprejudiced violence experience on multiple sexual partners through recreational drug use was 0.05 (95% CI: [0.03, 0.08]). These findings suggest that more comprehensive interventions are needed to address the syndemic of homoprejudiced violence, mental health issues, and HIV/STI-related risks.

Abstract
OBJECTIVES The sociocultural context of China gives rise to unique experiences of HIV-related stigma and adverse impacts on mental health among men who have sex with men (MSM) living with HIV. However, few studies have explored the stigma among families in the cultural context of China and the role of social support as a mediator to explain how HIV-related stigma results in poor psychological well-being. This study aims to test the mediating effect of social support between HIV-related stigma and family stigma on the mental health of MSM. METHODS This cross-sectional study recruited newly MSM with HIV in two cities (Beijing and Wuhan) in China as participants from February 2021 to August 2022. A total of 257 MSM with HIV were recruited for the study. The mediating effects were examined using mediation models (SAS PROC CAUSALMED). RESULTS The overall total effect of HIV-related stigma on mental health was β = -1.483 (bootstrap 95% CI = -1.881, -1.104 p < 0.001), and the mediating effect of social support was β = -0.321 (bootstrap 95% CI = -0.571, -0.167 p = .001). A higher level of stigma from family predicts lower mental health with an overall total effect of β = -1.487 (bootstrap 95% CI = -1.823, -1.101 p < 0.001), while the indirect effect (mediation effect) of social support on mental health is β = -0.281 (bootstrap 95% CI = -0.477, -0.142 p = .003). CONCLUSIONS Given the mediating effect of social support on mental health, programs enhancing social support and decreasing stigmatization should be designed to improve the mental health of MSM with HIV, the interventions are needed at both the family and community levels. Public health campaigns in China that frame HIV and same-sex behavior as chronic issues and normal phenomena can correct misinformation related to HIV and MSM that leads to stigma and negative emotional reactions.

J Med Internet Res 2023; 25:e49137. [PMID: 37910154 PMCID: PMC10652192 DOI: 10.2196/49137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 09/25/2023] [Accepted: 09/29/2023] [Indexed: 11/03/2023] Open
Abstract
BACKGROUND Gay geosocial networking apps, also known as "gay apps," have gained increasing popularity in the men who have sex with men (MSM) community. Certain sexuality traits and gay app use are both associated with high-risk sexual behaviors among MSM. However, little is known about the underlying mechanism of such relationships. OBJECTIVE Based on the uses and gratifications theory, this study aimed to test the mediation effect of gay app use on the relationship between sexuality traits (sexual compulsivity and sexual sensation seeking) and high-risk sexual behaviors (multiple sexual partners and unprotected anal intercourse) among MSM. METHODS A cross-sectional, multicenter study was conducted in Wuhan and Changsha, China, from August to October 2020. A representative sample of 402 MSM was recruited through respondent-driven sampling. A self-administered web-based structured questionnaire was used to collect data on sociodemographic information, high-risk sexual behaviors, gay app use, sexual compulsivity, and sexual sensation seeking. Path analysis was conducted to assess the mediation effect. RESULTS Our study revealed that 67.42% (n=271) of MSM used gay apps for seeking potential sexual partners, with 37.06% (n=149) of them engaging in unprotected anal intercourse, and 45.42% (n=218) of them having multiple sexual partners. Of the participants, 17.16% (n=69) reported significant sexual compulsivity, while 29.10% (n=117) reported significant sexual sensation seeking. Notably, gay app usage partially mediated the relationship between sexual compulsivity and multiple sexual partners but fully mediated the relationship between sexual compulsivity and unprotected anal intercourse. Furthermore, gay app usage partially mediated the relationship between sexual sensation seeking and multiple sexual partners but fully mediated the relationship between sexual sensation seeking and unprotected anal intercourse. CONCLUSIONS High-risk sexual behaviors are common among MSM. Most MSM rely on gay apps to find sexual partners, which, when combined with higher levels of sexual compulsivity and sexual sensation seeking, can increase the likelihood of engaging in high-risk sexual behaviors. Therefore, interventions aimed at reducing these behaviors among MSM should focus on addressing the use of gay apps, while also considering the influence of their sexuality traits on gay app use.

Abstract
BACKGROUND Systematic reviews and meta-analyses based on observational studies have shown voluntary medical male circumcision (VMMC) may reduce HIV risk among men who have sex with men (MSM). There is a lack of randomized controlled trial (RCT) data assessing the efficacy of VMMC. OBJECTIVE The primary objective of this study was to assess the efficacy of VMMC for preventing HIV acquisition among MSM who primarily engage in insertive anal sex. METHODS A multicenter RCT will be conducted among MSM in 8 cities in China. Eligible participants are men aged 18-49 years who self-report ≥2 male sex partners in the past 6 months, predominantly practice insertive anal sex, and are willing to undergo circumcision. Interested men who satisfy inclusion criteria will be tested for HIV 1 month before enrollment and at enrollment, and only those who are HIV negative will be enrolled. At baseline, all enrolled participants will be asked to report sociodemographic characteristics and sexual behaviors; provide a blood sample for HIV, syphilis, and herpes simplex virus type 2 testing; and provide a penile swab for human papillomavirus testing. Participants will be randomly assigned to the intervention or control group. Those in the intervention group will receive VMMC and undergo a web-based weekly follow-up assessment of postsurgery healing for 6 consecutive weeks. All participants will be tested for HIV at 3-, 6-, 9-, and 12-month follow-ups. All participants will also be asked to report sexual behaviors and undergo repeat herpes simplex virus type 2 and human papillomavirus testing at 6- and 12-month follow-ups. The primary end point is HIV seroconversion. Secondary end points are the safety and satisfaction with VMMC and the changes in sexual behaviors after VMMC. The grouped censored data will be analyzed by intention-to-treat approach. RESULTS Recruitment for the RCT began in August 2020 and continued through July 2022. Data collection is expected to be completed by July 2023, and full data analysis is going to be completed by September 2023. CONCLUSIONS This study will be the first RCT to assess the efficacy of VMMC in preventing HIV infection among MSM. Results from this trial will provide preliminary evidence for the potential efficacy of VMMC to reduce incident HIV infection among MSM.

Abstract
A man in his 60s with no relevant previous medical history presented to an urban, major trauma centre by ambulance after being found with a head injury in a nightclub. The paramedics reported he was hypoxic, hypotensive and tachycardic with altered mental status. At the emergency department, he had oxygen saturations of 85% despite high-flow oxygen and was hypotensive at 88/43mmHg. We were concerned the patient was haemorrhaging given the lack of response to oxygen therapy and their hypotension. However, an arterial blood gas (ABG) established a diagnosis of methemoglobinaemia. Methylthioninium chloride was promptly administered, and the patient's condition improved. He later reported using recreational drugs, including alkyl nitrites ('poppers'). He was monitored until his fraction of methaemoglobin returned to normal baseline levels with serial ABGs. He was discharged 24 hours later. It was suspected that his use of alkyl nitrites was the most likely cause of methaemoglobinaemia.

Abstract
INTRODUCTION Sexualized drug use (SDU), the use of psychoactive drugs in the context of sexual intercourse, has been identified as a risk factor for HIV among men who have sex with men (MSM) in Asia. Given the distinct social and cultural context of same-sex relationships and drug-using practice in Asia, we aimed to describe the prevalence of SDU in East and South Asian countries and its associations with condomless anal sex (CAI) and HIV status. Synthesizing SDU research in this region, including SDU definitions, prevalence and outcomes, provides insights to inform future research and improved programme planning, resourcing and advocacy. METHODS We systematically searched OVID Medline, OVID EMBASE, OVID Global Health, CINAHL, PsycINFO and SCOPUS publication databases for scientific articles published from 1990 to 2022 measuring SDU among MSM in East and South Asian countries. A narrative synthesis was utilized to describe key study attributes and findings, and meta-analyses using random pooled effect models were used to estimate SDU prevalence and its associations with CAI and HIV status. Subgroup meta-analyses, sensitivity analysis and assessment of publication bias examined potential sources of heterogeneity for the pooled SDU prevalence estimates. RESULTS AND DISCUSSION Of the 1788 publications screened, 49 publications met the selection criteria and 18 were suitable for meta-analyses. Findings highlight SDU definitions distinct from other regions but inconsistencies in the definition of SDU between studies that have been highlighted in research elsewhere. The pooled prevalence of recent SDU (past 12 months) was 13% (95% CI = 10-16%; I2 = 97.6) but higher when studies utilized self-administered surveys (15%; 95% CI = 12-19%; p<0.05). SDU was associated with greater odds of CAI (pooled odds ratio [OR] = 3.21; 95% CI = 1.82-5.66) and living with diagnosed HIV (OR = 4.73; 95% CI = 2.27-8.21). CONCLUSIONS SDU is common among MSM in East and South Asian countries, but varying SDU definitions limit between-study comparisons. Responses to SDU-related harms should consider local contexts, including specific drug types used and their relative risks.

Abstract
BACKGROUND Short tandem repeats (STRs) are important as common genetic markers in forensic identification and population genetics due to their highly polymorphic nature. AIMS To explore genetic polymorphisms of the Chinese Hunan Han population and further dissect genetic relationships among the Hunan Han and other populations from China. SUBJECTS AND METHODS In this study, samples of 394 unrelated healthy individuals from the Chinese Hunan Han population were analysed using 46 autosomal-STRs (A-STRs). Thirteen previously reported populations (6,378 individuals) from China were subsequently collected for population genetic analyses based on 23 shared A-STRs. RESULTS In the Hunan Han population, a total of 452 alleles were detected in 46 A-STRs with allelic frequencies spanning from 0.0013 to 0.5571. Except for the Penta D locus in linkage disequilibrium, the combined power of discrimination and combined power of exclusion for 45 A-STRs in the Hunan Han population were 0.999999999999999999999999999999999999999999999999510314 and 0.999999999999999726596, respectively. Results of interpopulation differentiations, principal component analysis, and phylogenetic relationship analyses uniformly showed that the Hunan Han have closer genetic affinities with Han populations from different Chinese regions and a geographically close ethnic minority group, namely the Hubei Tujia. CONCLUSION To summarise, these 46 A-STRs showed high polymorphism in the Chinese Hunan Han population for forensic practice.

HIV incidence and sexual behavioral correlates among 4578 men who have sex with men (MSM) in Chengdu, China: a retrospective cohort study. BMC Public Health 2021; 21:802. [PMID: 33902499 PMCID: PMC8077884 DOI: 10.1186/s12889-021-10835-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Accepted: 04/13/2021] [Indexed: 01/22/2023] Open
Abstract
Background The prevalence of HIV among men who have sex with men (MSM) in southwest China is still increasing. This study aimed to investigate the trend in HIV incidence and its associated risk factors among MSM in Chengdu, China. Method Incidence data were collected from the largest local non-governmental organization (NGO) serving MSM in Chengdu between 2012 and 2018, while information on sexual behaviors was collected from 2014. All MSM who received voluntary counseling and testing services (VCT) in the collaborating NGO at least twice during the study period were included. We calculated the HIV incidence density among MSM every 2 years and the overall incidence rate. A Cox proportional hazards regression model was employed to identify risk factors for HIV infection. Result A total of 4578 HIV-negative participants were included in the cohort. The total incidence density was 5.95 (95% CI: 5.37–6.56)/100 person-years (PYs) between 2012 and 2018. The segmented incidence density was 9.02 (95% CI: 7.46–10.78), 5.85 (95% CI: 4.86–6.97), 5.43 (95% CI: 4.53–6.46), and 3.09 (95% CI: 2.07–4.41)/100 PYs in 2012–2013, 2014–2015, 2016–2017, and 2018, respectively. After adjusting for sociodemographic characteristics, compared to participants without sexual partners within 6 months, MSM with one fixed partner (Adjusted Hazard Ratio, AHR = 1.18, 95% CI: 0.44–3.19) and more than five partners (AHR = 2.24, 95% CI: 0.81–6.20) had increased risk of HIV infection. MSM who used condom inconsistently had a higher risk of HIV infection (AHR = 1.87, 95% CI: 1.46–2.38) compared to consistent condom users. Conclusion The decreased HIV incidence density among MSM was potentially related to the successful comprehensive HIV prevention strategies in Chengdu. Multiple male sexual partnerships and inconsistent condom use during anal intercourse were risk factors associated with HIV occurrence.

Abstract
OBJECTIVES Inhalants are substances with underestimated abuse potential associated with cardiac problems, dizziness, seizures, and decreased level of consciousness. Inhalants are commonly used by the LGB population, who are vulnerable to their harms. US epidemiologic inhalants data are scarce. The aims of this study are to: i) investigate associations between inhalant use and sexual identity groups; ii) examine associations with use of other drugs among lesbian/gays who use inhalants. METHODS Data came from the 2015-2018 NSDUH (n = 168,560). Participants ages 18 or older were asked if they had used any inhalants in their lifetime and past-year. We investigated the associations between inhalant use with sexual identity categories heterosexual, lesbian/gay, and bisexual using logistic regression models with complex survey design. RESULTS Total prevalences of lifetime and past-year use of inhalants were 9.4% and 0.5%, respectively. Lesbian/gay population (L/G) and bisexuals (B) reported higher odds of lifetime (L/G: aOR = 3.71, 95%CI = [3.19,4.30], B: aOR = 1.82, 95%CI = [1.64,2.03) and past-year (L/G: aOR = 11.57, 95%CI = [8.95,14.96], B: aOR = 2.81, 95%CI = [2.02,3.92]) inhalant use compared to heterosexuals. Among L/G, men had higher odds of lifetime (aOR = 4.11, 95%CI = [3.06,5.52]) and past-year (aOR = 15.67, 95%CI = [7.27,33.76]) inhalant use versus women. Use of marijuana (aOR = 2.76, 95%CI = [1.48,5.16]), other illegal drugs (aOR = 2.70, 95%CI = [1.60,4.56]), and non-medical use of psychotherapeutics (aOR = 2.67, 95%CI = 1.77,4.05) were associated with past-year use of inhalants among L/G. CONCLUSION LGB population is at elevated risk of inhalant use and of concurrent use with other drugs. Gay men had significantly higher odds of inhalant use compared to lesbians and bisexuals. Informative and in-site harm reduction measures are warranted to prevent harms from inhalant use.

Abstract
BACKGROUND Findings from specific countries indicated group sex was common among men who have sex with men (MSM), and men who reported group sex participation were at increased risk of human immunodeficiency virus (HIV)/sexually transmitted infections (STIs). The purpose of the current analysis was to describe the prevalence and correlates of group sex participation among a community-based sample of MSM in Chongqing, southwestern China. METHODS Convenience sampling method was used to recruit participants and data were collected through an anonymous questionnaire. Logistic regression analysis was employed to identify correlates of group sex participation. RESULTS Overall, 1151 eligible participants were enrolled in the study. 14.7% of MSM reported participating in group sex in their lifetime, and 5.8% reported group sex participation in the prior 6 months. Factors positively associated with group sex participation in both the prior 6 months and the lifetime included: monthly income ≥3000 Yuan (adjusted odds ratios [aOR] = 3.67, 95% confidence interval [CI] 1.25-10.75; aOR = 2.30, 95% CI 1.21-4.35), initiating anal sex before 18 years old (aOR = 1.86, 95% CI 1.03-3.34; aOR = 2.00, 95% CI 1.31-3.05), using gay apps to seek sex partners (aOR = 7.41, 95% CI 2.57-21.33; aOR = 9.75, 95% CI 4.92-19.33), recreational drug use (aOR = 10.10, 95% CI 5.52-18.49; aOR = 4.75, 95% CI 3.20-7.05) and having condomless internal ejaculation (CIE) (aOR = 3.66, 95% CI 2.01-6.68; aOR = 1.61, 95% CI 1.11-2.35). Factors only associated with group sex participation in the lifetime were older age (age between 26 and 35 years old: aOR = 2.06, 95% CI 1.30-3.26; age > 35 years old: aOR = 1.95, 95% CI 1.10-3.46) and history of STIs (aOR = 2.51, 95% CI 1.37-4.62). CONCLUSIONS The results of this study suggested that group sex participation was a potentially risky context for acquisition and transmission of HIV/STIs. Close attention should be given to MSM who participated in group sex, and appropriate risk reduction interventions should be developed specific to this subgroup of MSM.

Social capital and chemsex initiation in young gay, bisexual, and other men who have sex with men: the pink carpet Y cohort study. SUBSTANCE ABUSE TREATMENT PREVENTION AND POLICY 2021; 16:18. [PMID: 33608005 PMCID: PMC7893730 DOI: 10.1186/s13011-021-00353-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Accepted: 02/08/2021] [Indexed: 02/02/2023]
Abstract
Background Young gay, bisexual, and other men who have sex with men (YMSM) are especially vulnerable to the risks associated with sexualized substance use, or ‘chemsex’. Engaging in chemsex established as a major risk factor for Human Immunodeficiency Virus (HIV) acquisition, and is thus a public health issue of increasing urgency. This paper attempts to explore the association between measures of social capital and patterns of sexualized substance use among a sample of YMSM in Singapore. Methods Results of this study were derived from baseline data of the Pink Carpet Y Cohort Study in Singapore, comprising a sample of 570 HIV-negative YMSM aged 18 to 25 years old. Latent class analysis was employed to identify classes with similar patterns of sexualized substance use, and multinomial logistic regression was employed to examine associations between class membership and proxy measures of social capital, including age of sexual debut, bonding and bridging social capital, connectedness to the lesbian, gay, bisexual and transgender community, and outness. Results Latent class analysis revealed three classes of YMSM based on their histories of sexualized substance use, which we labelled as ‘alcohol’, ‘poppers’, and ‘chemsex’. Multivariable analyses revealed that participants who were older (aOR = 1.19, p = 0.002) and who identified as gay (aOR = 2.43, p = 0.002) were more likely to be in the poppers class compared to the alcohol class. Participants with a later age of sexual debut were increasingly less likely to be in the poppers (aOR = 0.93, p = 0.039) and chemsex classes (aOR = 0.85, p = 0.018), compared to the alcohol class. Conclusions Varying measures of social capital such as an earlier age of exposure to sexual networks may predispose YMSM to greater opportunities for sexualized substance use. Future interventions should target YMSM who become sexually active at an earlier age to reduce the risks associated with sexualized substance use.

The use of inappropriate anal douching tool associates with increased HIV infection among men who have sex with men: a cross-sectional study in Shenyang, China. BMC Public Health 2021; 21:235. [PMID: 33509136 PMCID: PMC7844917 DOI: 10.1186/s12889-021-10276-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Accepted: 01/19/2021] [Indexed: 11/10/2022] Open
Abstract
Background Rectal douching (RD) is widely practiced by men who have sex with men (MSM), and is associated with increased risk of HIV infection. However, the mechanism of how RD increases the risk of HIV infection is not well understood, and there is limited data on RD behavior in MSM practicing anal sex in China. We examine the purpose of RD, its timing in relation to anal sex, the types of RD products used, and risky sexual behaviors among MSM reporting anal sex. Methods Between August 2017 and December 2018, a cross-sectional study was conducted among adult MSM in Shenyang, China. Data were collected on demographics, sexual behaviors, and RD for the most recent sexual intercourse by means of interviewer-administered face-to-face questionnaires. Blood samples were collected to test for antibodies to HIV and syphilis. Multivariable logistic regression models were used to assess the risk factors associated with HIV infection. Results A total of 515 eligible MSM participated in this survey (median age: 31 years). During the most recent anal intercourse, 28.3% (146/515) had condomless receptive anal intercourse (CRAI), 21.4% (110/515) practiced serosorting, and more than half (61.6%, 317/515) reported RD before or after anal sex. Of those practicing RD, 96.8% (307/317) conducted RD before sex, while 62.5% (198/317) conducted RD after sex. The douching devices used were primarily shower hoses (85.3%, 262/307), and relatively few MSM used commercial RD products (8.1%, 25/307) before sex. The prevalence of HIV-1 and syphilis was 11.7% and 13.2%, respectively. HIV infection was positively associated with RD, practicing RD before sex, the interaction between RD and CRAI using a shower hose for RD and other risk factors, practicing RD after sex, CRAI, using nitrite inhalants, main sexual role with males as bottom and syphilis infection. Conclusions RD is popular among Chinese MSM. Improper noncommercial RD tools use (such as shower hose), the interaction effect between RD and CRAI associated with HIV infection. Public health workers and the MSM community should publicize scientific knowledge and prevention approaches relating to RD and HIV transmission to MSM. We recommend that further studies should be conducted to understand the detailed mechanism between RD and increased HIV prevalence.

[PMID: 32887643 PMCID: PMC7650275 DOI: 10.1186/s40249-020-00748-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Accepted: 08/31/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Emerging evidence indicates nitrite inhalants have become increasingly prevalent among men who have sex with men (MSM). The present study aimed to describe the prevalence and correlates of nitrite inhalants use and its association with risky sexual behaviors and human immunodeficiency virus (HIV)/syphilis infection among MSM in Chongqing, a city in China where MSM were burdened with the highest pooled HIV prevalence in the country. METHODS This cross-sectional study was conducted in Chongqing between March 2019 and February 2020. Information of demographics, drug use, sexual behaviors and HIV testing was collected through an anonymous survey. Blood samples were drawn from each participant for the diagnoses of HIV and syphilis. Logistic regression analysis was performed to evaluate factors correlated with nitrite inhalants use and its relationship with risky sexual behaviors and HIV/syphilis infection. RESULTS Of the 1151 eligible participants, 18.9% (218) reported use of at least one type of recreational drugs in the past 6 months, and nitrite inhalants were the most commonly used substance (17.7, 95% confidence interval [CI]: 15.6-20.2%). The proportions of participants reported engaging in group sex and practicing condomless internal ejaculation during anal sex in the past six months were 5.8% (95% CI: 4.4-7.2%) and 41.7% (95% CI: 38.7-44.7%), respectively. The general prevalence of HIV and syphilis infection among the enrolled MSM were 16.8% (95% CI: 14.7-19.0%) and 12.6% (95% CI: 10.7-14.4%), respectively. Factors positively associated with nitrite inhalants use included: age ≤ 25 (adjusted odds ratio [aOR] = 2.08, 95% CI: 1.10-3.94), monthly individual income ≥ CNY 3000 (Chinese Yuan) (aOR = 1.95, 95% CI: 1.18-3.22), preferring receptive anal intercourse (aOR = 2.27, 95% CI: 1.34-3.84) and versatile anal intercourse (aOR = 2.60, 95% CI: 1.64-4.13), age at first anal intercourse < 18 (aOR = 1.79, 95% CI: 1.21-2.67), engaging in group sex in the past six months (aOR = 9.34, 95% CI: 4.95-17.63), having multiple male sex partners in the past 6 months (aOR = 2.32, 95% CI: 1.50-3.58), practicing CIE during anal sex in the past six months (aOR = 1.71, 95% CI: 1.19-2.46), HIV infection (aOR = 1.72, 95% CI: 1.11-2.66) and syphilis infection (aOR = 1.98, 95% CI: 1.23-3.17). CONCLUSIONS This study found that nitrite inhalants were the most commonly used recreational substance among MSM and nitrite inhalants use were associated with higher probability of HIV and syphilis infection. Therefore, increased attention and counselling should be given to nitrite inhalants-using MSM.

Abstract
INTRODUCTION Pre-exposure prophylaxis (PrEP) reduces the risk of HIV infection among men who have sex with men by up to 99%. However, in real-world settings, PrEP users may exhibit risk compensation after uptake of PrEP, including more condomless anal intercourse (CAI) and increased sexually transmitted infection (STI) acquisition. HIV self-testing (HIVST) decreases CAI among men who have sex with men (MSM) by providing awareness of the HIV status of oneself and one's sexual partners. Here, we describe the rationale and design of a randomised waitlist-controlled trial to examine the impact of HIVST on risk compensation among PrEP users. METHODS AND ANALYSIS The study is a two-arm randomised waitlist-controlled trial with 1000 HIV-negative MSM in four major cities in China who will be taking oral PrEP (involving tenofovir disoproxil fumarate/emtricitabine) either daily (n=500) or in an event-driven regimen (n=500). The participants will be randomised (1:1) to either the immediate HIVST intervention arm (HIVST plus standard facility-based counselling and testing from 0 to 12 months) or the waitlist arm (standard facility-based counselling and testing from 0 to 6 months, then crossover to receive the HIVST intervention in months 7-12). Participants will provide blood samples to assess the incidence of syphilis and herpes simplex virus type 2 (HSV-2) during a follow-up. The primary outcomes will be the occurrence of CAI, number of sexual partners and incidence of syphilis and HSV-2 during a follow-up. The secondary outcomes will be the HIV and STI testing frequency and STI treatment adherence during a follow-up. The planned start and end dates for the study is 26 December 2018 and 31 December 2020. ETHICS AND DISSEMINATION The Medical Science Research Ethics Committee of The First Affiliated Hospital of China Medical University has approved the study (IRB(2018)273). TRIAL REGISTRATION NUMBER ChiCTR1800020374.

Abstract
We sought to estimate the prevalence as well as demographic and drug use-related correlates of poppers use among adults in the United States. Data were analyzed from adult participants (ages 18-64) in the 2015-2017 National Survey on Drug Use and Health (N = 115,744), a nationally representative survey of non-institutionalized adults in the US. An estimated 3.3% of adults have ever used poppers. Over a third (35.1%) of gay men are estimated as having ever used poppers. Estimates were lower for heterosexual (3.7%) and bisexual males (11.3%), and for heterosexual (1.8%), bisexual (4.8%), and lesbian women (6.3%). In the multivariable model, compared to male heterosexuals, gay men were at increased odds for reporting lifetime popper use (aOR = 24.64, p<.001), and bisexual men (aOR = 3.55, p <.001), lesbian women (aOR = 1.86, p =.010), and bisexual women (aOR = 1.33, p =.049) were at increased odds for lifetime use. Having a college degree was associated with increased odds for use, and lifetime use of marijuana, ecstasy/MDMA/Molly, cocaine, LSD, methamphetamine, tranquilizers, and/or opioids were associated with higher odds for use. Gay men in particular are at high risk for use. Results can help inform prevention efforts, particularly in sexual minority populations.

Abstract
BACKGROUND There is increasing evidence that HIV-1 genetic diversity can have an impact on drug resistance. The aim of this study is to investigate the epidemiological situation of CRF65_cpx and the impact of natural polymorphisms of this variant on genotypic resistance. METHODS We used the BLAST search program followed by phylogenetic analysis to identify additional CRF65_cpx pol sequences from the Los Alamos HIV Sequence Database. Maximum likelihood phylogeny was estimated to clarify the epidemiological relationship of CRF65_cpx strains. Genotypic resistance was determined by submitting sequences to the Stanford HIV Drug Resistance Database. RESULTS A total of 32 CRF65_cpx pol sequences were obtained. The CRF65_cpx strains were detected in seven provinces with large geographic distance. Yunnan CRF65_cpx sequences were mainly derived from a heterosexual risk group, whereas the CRF65_cpx sequences in other provinces were almost exclusively derived from an MSM population. With one exception of V179E, the other 31 strains harbored V179D mutation. The combination of V179D and K103R, conferring intermediate resistance to EFV and NVP, was detected in seven treatment-naive MSM patients. CONCLUSIONS This study confirmed the expansion CRF65_cpx in China. Furthermore, we found the natural presence of the V179D and K103R/V179D mutations associated with resistance to NNRTIs in HIV-1 CRF65_cpx. Our findings highlight the contribution of polymorphic mutations to drug resistance and underscore the challenges in treating patients harboring CRF65_cpx strains.

Network Evolution of a Large Online MSM Dating Community: 2005-2018. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16224322.

Abstract
Due to multiple sexual partners and low rates of condom use, the HIV infection rate among MSM (men who have sex with men) is much higher than that of the general population. In order to analyze the characteristics of online activities of MSM, and to understand the evolution of their social networks, in this study we collect a comprehensive dataset, covering the period from January 2005 to June 2018, from the largest Chinese online community, Baidu Tieba. We build an online dating network for MSM-related individuals in the gay-bar community, and analyze the network from static and dynamic aspects. It is found that there is a strong homophily regarding the cities where users reside when developing interactions with others, and that most network measurements tend to be stable at the later stages of evolution, while the size of the largest community fluctuates. This is an indication that the network is formed of rapidly flexible interactions which changes quickly. In comparison with studies on heterosexual networks, we find that the MSM dating network shows differences in many aspects, such as the positive degree-degree correlation and high clustering coefficient, suggesting different thinking and measures should be taken in the policy making of public health management towards the MSM population.

Abstract
Prospective cohort studies have been conducted to estimate HIV incidence among men who have sex with men (MSM) in first-line megacities cities (>10 million residents) in China, but few in the second-line large- or middle-size cities. This study was to investigate HIV incidence and cohort retention among MSM in a second-line city Hangzhou in eastern China.A total of 523 HIV-seronegative MSM were recruited during September 2014 to September 2015, and were followed up prospectively at 3, 6, 9, and 12 months. Questionnaire interviews were conducted, and laboratory tests were performed to evaluate baseline syphilis infection and HIV seroconversions. Chi-square test and logistic regression model were used to identify factors associated with cohort retention rate and syphilis prevalence.Of 523 participants, 137 (26.2%) completed 6-month follow-up, and use of Internet for recruiting study participants (vs other recruitments: adjusted odds ratio [AOR] = 0.5; 95% confidence interval [CI]: 0.3-0.8) and being homosexual (vs heterosexual or bisexual: AOR = 0.6; 95% CI: 0.4-0.9) were associated with lower cohort retention. The overall HIV incidence during 12 months of follow-up was 6.6 per 100 person-years (95% CI: 3.4-9.8/100 PY). The prevalence of syphilis at baseline was 6.5% (95% CI: 4.4%-8.6%), and disclosing sexual orientation (AOR = 0.4, 95% CI: 0.2-0.9) was associated with lower risk of syphilis infection.HIV is spreading rapidly among MSM in the second-line Chinese city. Effective interventions are needed to target this population in both first-line megacities and second-line large and middle-size cities.

Abstract
OBJECTIVES Limited research has been conducted to investigate the characteristics of money boys (MBs) in China. This study was aimed to identify the subgroups of MBs based on sexual behaviors, Net-based venue sex-seeking, and substance abuse. STUDY DESIGN Cross-sectional study. METHODS Convenience sampling was used to recruit MBs from December 2014 to June 2015 in Tianjin, China. Face-to-face interviews were conducted for 330 MBs, and trained interviewers collected data. RESULTS The laboratory-confirmed human immunodeficiency virus (HIV)-positive rate was 11.52% among 330 MBs. Four classes were identified through latent class analysis (LCA) method: 'relatively safe behavior' group, 'higher sexual risk' group, 'multiple sexual-partners' group, and 'unprotected sex and substance abuse' group, and there is a significant difference based on the HIV status. Significant differences were found in original residence, monthly income, duration in sex trade, employment, history of sexually transmitted infection (STI), HIV testing, knowledge of free antiviral treatment policy, and awareness of free AIDS testing between the four latent classes (P < 0.05). MBs who used Net-based venues to seek sexual partners; who have inconsistent condom use, substance abuse, a longer duration in sex trade, multiple sexual clients, and multiple anal sex; and who were full-time employed had the highest risk of HIV infection. CONCLUSIONS The utility of LCA to identify subgroups based on risky behaviors attributes to formulating targeted intervention strategy.
