Prevalence of HIV and syphilis and their co-infection among men having sex with men in Asia: A systematic review and meta-analysis. Heliyon 2023; 9:e13947. [PMID: 36895383 PMCID: PMC9988516 DOI: 10.1016/j.heliyon.2023.e13947] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 02/08/2023] [Accepted: 02/15/2023] [Indexed: 02/23/2023] Open
Abstract
Background Studies found that the group of men who have sex with men (MSM) is at a very high level of risk of HIV and sexually transmitted infections (STIs) in Asian regions due to multiple reasons. Although the prevalence of HIV among general people in Asia is considered low, the prevalence of HIV and Syphilis among MSM in this region was found very high and usually, it goes unnoticed. This study aimed to inspect the prevalence of and trends in HIV, Syphilis, and their co-infection among MSM in Asia. Methods A systematic search was performed on January 5, 2021, in PubMed, Web of Science, and Google Scholar databases. To evaluate the heterogeneity, Q-tests, and I 2 were used. To explore the publication bias, Eggers' test and funnel plot were used. The random-effect model and subgroup analysis were performed due to the significant heterogeneity. Results A total of 2872 articles were identified, and 66 articles were included in the final analysis. The overall prevalence of HIV and Syphilis among MSM was estimated considering 69 estimates from 66 studies whereas 19 estimates of co-infection were found in 17 studies. The pooled HIV prevalence was 8.48% (CI: 7.01-9.95) and the pooled Syphilis prevalence was 9.86% (CI: 8.30-11.41) with significant heterogeneity and publication bias. The pooled prevalence of HIV and Syphilis co-infection was 2.99% (CI: 1.70-4.27) with significant heterogeneity and no publication bias. The HIV, Syphilis, and HIV-Syphilis co-infection prevalence estimates exhibited an upward trend during 2002-2017. Conclusions HIV, Syphilis, and their co-infection are quite prevalent among MSM in the Asia-Pacific region. Integrated and intensified intervention strategies, HIV testing, and improved access to antiretroviral treatment as well as increased awareness are needed to reduce HIV, Syphilis, and their co-infection among the discussed vulnerable group.

Front Med (Lausanne) 2022; 9:904873. [PMID: 35721088 PMCID: PMC9205561 DOI: 10.3389/fmed.2022.904873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Accepted: 05/09/2022] [Indexed: 11/13/2022] Open
Abstract
Background Men who have sex with men (MSM) are at high risk for human papillomavirus (HPV) infection. A community-based organization (CBO)-private clinic service model promoting HPV vaccination among MSM was implemented in Hong Kong. The aim of this study was to evaluate the effectiveness of this service model in increasing HPV screening among MSM. Methods This was a secondary analysis of the CBO-private clinic service model in increasing HPV screening among MSM. Participants were Hong Kong Chinese-speaking MSM aged 18–45 years who had never received HPV vaccination. All participants completed a telephone survey at baseline before receiving online intervention promoting HPV vaccination and completed another telephone survey 12 months afterward. Results A total of 350 participants completed a baseline telephone survey and received interventions promoting HPV vaccination. Among 274 participants being followed up at Month 12, 33 (12.0%) received any type of HPV screening during the study period. Such uptake rate was similar to the prevalence of HPV screening in the past year measured at baseline (12.0 vs. 9.9%, p = 0.43). More MSM preferred HPV vaccination or HPV vaccination plus HPV screening, and very few preferred HPV screening alone. After adjusting for significant baseline characteristics, higher perceived susceptibility to HPV (adjusted odds ratio (AOR): 1.16, 95% confidence interval (CI): 1.00–1.34) and receiving HPV vaccination during the study period (AOR: 7.03, 95% CI: 3.07–16.13) were significantly associated with higher HPV screening uptake. Conclusions The CBO-private clinic service model promoting HPV vaccination had limited impact in increasing HPV screening among MSM in Hong Kong. MSM in Hong Kong may not use HPV screening as an alternative prevention strategy to HPV vaccination. Future programs preventing HPV-related diseases among MSM in Hong Kong should focus on HPV vaccination promotion.

Abstract
BACKGROUND Risk of anal squamous cell carcinoma (anal cancer) is greater among men who have sex with men (MSM) living with human immunodeficiency virus (HIV). We describe the frequency of and factors associated with abnormal anal cytology results in Colombian MSM living with HIV. METHODS This retrospective observational cohort study included MSM ≥18 years old living with HIV screened with anal cytology at Hospital Universitario San Ignacio in Bogotá, Colombia between January 2019 and February 2020. A multivariable log-binomial regression model estimated associations with abnormal anal cytology. RESULTS A total of 211 patients were included. Mean age was 35.6 years. Sixty-eight (32.3%) had an abnormal anal cytology result: ASC-US 33.8% (n = 23); LSIL 60.3% (n = 41); and HSIL 5.9% (n = 4). MSM with an STI diagnosis in the previous 12 months (RR 1.48, [95% CI 1.03-2.12], p = 0.032) or with a CD4+ T cell count <200 (RR 2.08 [95% CI 1.16-3.73], p = 0.014) were significantly more likely to have abnormal anal cytology. CONCLUSIONS These data provide crucial information to guide scale up of anal cancer screening at select centers in Colombia. Our results also suggest STI prevention efforts and improved virological control among MSM living with HIV may have the secondary benefit of reducing the risk of anal cancer.

Abstract
Objective Men who have sex with men (MSM) are at increased risk for Human papillomavirus (HPV) infection compared to women and heterosexual men. We aimed to assess the incidence, clearance and duration of anal human papillomavirus (HPV) infection in HIV-negative MSM and the influencing factors in a 5-year prospective cohort study. Methods From April 2016 to April 2021, HIV-negative MSM were recruited and followed every 6 months in Urumqi, Xinjiang, China. Questionnaires and anal swabs were collected at baseline and every 6 months. We detected 37 anal HPV genotypes using the HPV Geno Array Diagnostic Kit Test. Incidence and clearance rates of anal HPV infection and the influencing factors were estimated using a two-state Markov model. Results A total of 585 MSM were included with a median age of 37 years [interquartile range (IQR): 31–43 years] and were followed for a median 2.8 years (IQR: 1.8–3.6 years). Incidence rates for any HPV and high-risk HPV (Hr-HPV) were 53.4 [95% confidence interval (CI): 49.1–58.0] and 39.0 (95% CI: 35.7–42.5)/1,000 person-months. Median duration of infection was 9.67 (95% CI: 8.67–10.86) and 8.51 (95% CI: 7.57–9.50) months, respectively. Clearance rates for any HPV and Hr-HPV were 50.9 (95% CI: 46.7–55.3) and 62.1 (95% CI: 56.8–66.7)/1,000 person-months, respectively. HPV16 and HPV6 had the highest incidence, lowest clearance rate and longest duration of infection among Hr-HPV and low-risk HPV (Lr-HPV) types, respectively. Receptive anal sex is a risk factor for any HPV [hazard ratio (HR) = 1.66, 95% CI: 1.16–2.38] and Hr-HPV infection (HR = 1.99, 95% CI:1.39–2.85). Recent anal sex without condom use was significantly associated with any HPV (HR = 1.80, 95% CI: 1.10–2.94) and Hr-HPV infection (HR = 2.60, 95% CI: 1.42–4.77). Age ≥35 years was significantly associated with Lr-HPV HPV infection only (HR = 1.40, 95% CI: 1.02–1.93). Both inserted and receptive anal sex (HR = 0.60, 95% CI: 0.40–0.89) and anal sex ≥2 times per week (HR = 0.61, 95% CI: 0.43–0.87) were associated with reduced Hr-HPV clearance. Six of the nine-valent vaccine types (HPV6, 11, 16, 18, 52 and 58) occurred most frequently, which indicates the need for high vaccination coverage in MSM. Conclusions In this cohort study, high incidence and low clearance of any HPV, Hr-HPV and individual HPV infections emphasize the importance of MSM vaccination. Modifiable behavioral factors such as condoms and drug use should be incorporated into HPV prevention strategies.

Abstract
This study evaluated the effectiveness of the community-based organization (CBO)-private clinic service model in increasing human papillomavirus (HPV) vaccination uptake among unvaccinated men who have sex with men (MSM) in Hong Kong during a 12-month follow-up period. A CBO-private clinic model was implemented to promote HPV vaccination among Chinese MSM. A CBO with good access to MSM approached MSM aged 18–45 years who had never received an HPV vaccination, invited them to receive an online health promotion, and referred them to receive HPV vaccination at gay-friendly private clinics. A baseline survey and a follow-up evaluation at Month 12 were conducted. A total of 350 participants completed the baseline survey. Among 274 participants who were followed up at Month 12, 46 (16.8%) had taken up at least one dose of HPV vaccination. After adjusting for significant baseline characteristics, the perceived susceptibility (AOR:1.25, p = 0.002) and perceived severity (AOR:1.21, p = 0.003) of HPV and HPV-related diseases, perceived benefits (AOR:1.16, p = 0.03), self-efficacy to receive HPV vaccination (AOR:1.37, p = 0.001), and behavioral intention to take up HPV vaccination at baseline (AOR:6.99, p < 0.001) significantly predicted HPV vaccination uptake. The process evaluation of the program was positive. The CBO-private clinic service model was helpful in increasing HPV vaccination uptake among MSM.

Abstract
Currently, homosexual transmission has become one of the main routes of HIV-1 spread in China. Furthermore, about 80% Chinese men, who have sex with men (MSM), feel forced to enter eventually into heterosexual marriages due to the Chinese traditional marriage culture, which may cause HIV-1 infection in families. In this study, we identified HIV-1 transmission in a family and the direction of HIV-1 transmission from a MSM to his wife and infant, which indicated Chinese MSM may have become a potential bridge of HIV-1 transmission to their wives and children. Therefore, we need to develop more effective defence measures to prevent the spread of HIV-1 in MSM families in China.

Abstract
Regular tests for human papillomavirus (HPV) and early treatment could represent an important strategy for preventing anal cancers among men who have sex with men (MSM). This study investigated facilitators and barriers to take up clinician-collected and self-collected HPV tests among Chinese MSM. This study was based on the baseline sample of a longitudinal study promoting HPV vaccination among 350 Chinese MSM who had never received an HPV vaccination. The baseline survey was conducted from August 2019 to April 2020. The prevalence of any HPV tests uptake in lifetime was 19.1%; 4.9% had HPV infection in anus, genital, oral cavity, and other places. Among the participants, 20% and 76.8% intended to take up self-financed and free clinician-collected HPV tests, and 76.8% intended to use free self-collected HPV tests. After adjusting for significant background characteristics, perceived risk of HPV infection, and perceived benefits, barriers, cue to action, and self-efficacy related to HPV tests in general and/or specific to self-collected HPV tests were associated with behavioral intention to take up free clinician-collected and/or self-collected HPV tests. Less than 20% of Chinese MSM reported HPV tests uptake. Modifying perceptions related to HPV tests may be useful to increase HPV tests coverage in this group.

Abstract
A co-infection model for human papillomavirus (HPV) and syphilis with cost-effectiveness optimal control analysis is developed and presented. The full co-infection model is shown to undergo the phenomenon of backward bifurcation when a certain condition is satisfied. The global asymptotic stability of the disease-free equilibrium of the full model is shown not to exist when the associated reproduction number is less than unity. The existence of endemic equilibrium of the syphilis-only sub-model is shown to exist and the global asymptotic stability of the disease-free and endemic equilibria of the syphilis-only sub-model was established, for a special case. Sensitivity analysis is also carried out on the parameters of the model. Using the syphilis associated reproduction number, [Formula: see text], as the response function, it is observed that the five-ranked parameters that drive the dynamics of the co-infection model are the demographic parameter [Formula: see text], the effective contact rate for syphilis transmission, [Formula: see text], the progression rate to late stage of syphilis [Formula: see text], and syphilis treatment rates: [Formula: see text] and [Formula: see text] for co-infected individuals in compartments [Formula: see text] and [Formula: see text], respectively. Moreover, when the HPV associated reproduction number, [Formula: see text], is used as the response function, the five most dominant parameters that drive the dynamics of the model are the demographic parameter [Formula: see text], the effective contact rate for HPV transmission, [Formula: see text], the fraction of HPV infected who develop persistent HPV [Formula: see text], the fraction of individuals vaccinated against incident HPV infection [Formula: see text] and the HPV vaccine efficacy [Formula: see text]. Numerical simulations of the optimal control model showed that the optimal control strategy which implements syphilis treatment controls for singly infected individuals is the most cost-effective of all the control strategies in reducing the burden of HPV and syphilis co-infections.

Abstract
Background Human papillomavirus (HPV) vaccination is effective in the prevention of vaccine-type genital warts and cancers among men who have sex with men (MSM). Objective The primary objective of this randomized controlled trial (RCT) is to evaluate the efficacies of 2 web- and theory–based interventions with and without brief motivational interviewing (MI) over the phone to increase the completion of HPV vaccination among unvaccinated participants within a 24-month follow-up period compared with the control group. Methods A 3-arm parallel-group RCT was conducted between July 2017 and December 2019. Five telephone surveys were conducted at baseline and at 3, 6, 9, and 24 months by blinded interviewers. Participants were Hong Kong Chinese–speaking MSM aged between 18 and 45 years with regular internet access who were recruited from outreaching at venues, web-based recruitment, and peer referral. Those who had ever received HPV vaccination were excluded. A total of 624 participants were randomized into either the online tutorial (OT) only group (n=208), the OT plus MI group (OT-MI; n=208), or the control group (n=208). In total, 459 (459/624, 73.6%) completed the follow-up evaluation at 24 months. Participants in the OT group received a fully automated OT developed based on the health belief model. On top of the same OT, the OT-MI group received brief MI over the phone. Reminders were sent to the participants of the OT and OT-MI groups after 1, 2, 4, 6, and 8 months. Participants in the control group received web-based health communication messages unrelated to HPV or HPV vaccination. The research team validated the self-reported HPV vaccination uptake. Intention-to-treat analysis was used for outcome analyses. Logistic regression models and multivariable linear regression models were used to test the between-group differences in primary and secondary outcomes. Baron and Kenny’s methods were used to test the mediation hypothesis. Results The participants in the OT-MI group reported a significantly higher validated completion of HPV vaccination at 24 months than the control group (36/208, 17.3% vs 15/208, 7.2%; P=.006). However, the difference in HPV vaccination completion between the OT and the control groups (24/208, 11.5% vs 15/208, 7.2%; P=.17), or between OT-MI and OT groups (P=.13), was not statistically significant. The association between randomization status (OT-MI group vs control group) and HPV vaccination completion became statistically nonsignificant after controlling for changes in the perceived susceptibility to HPV (24 months vs baseline), whereas perceived susceptibility remained strongly associated with HPV vaccination uptake in the model (P<.001). Changes in perceived susceptibility fully mediated the intervention effect. Conclusions Theory-based OT with brief MI over the phone was effective in increasing HPV vaccination completion among Chinese MSM. Perceived susceptibility is an active theoretical component that causes behavioral changes. Trial Registration ClinicalTrials.gov NCT03286907; https://clinicaltrials.gov/ct2/show/NCT03286907

Farahmand M, Monavari SH, Tavakoli A. Prevalence and genotype distribution of human papillomavirus infection in different anatomical sites among men who have sex with men: A systematic review and meta-analysis. Rev Med Virol 2021; 31:e2219. [PMID: 33527636 DOI: 10.1002/rmv.2219] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 01/07/2021] [Accepted: 01/12/2021] [Indexed: 12/15/2022]
Abstract
Men who have sex with men (MSM) are at increased risk of human papillomavirus (HPV) infection because of their high-risk sexual behaviours. In this study, a meta-analytic approach was used to systematically analyse the literature to elucidate the prevalence and genotype distribution of anal, penile, oral and urethral HPV infection among MSM in the world. To carry out this systematic review, five electronic databases including Web of Science, PubMed, Scopus, Embase, and Google Scholar were searched for relevant studies published from January 2012 to November 2019, and pertinent data were collected from the eligible articles. The pooled HPV prevalence was calculated for each anatomical region using a random-effect model weighted by the inverse variance method. The meta-analysis was performed using the "Metaprop" function in the R package Meta. The overall pooled prevalence of anal, penile, oral and urethral HPV infection among MSM were 78.4% (95% confidence interval [CI]: 75.6%-81.0%), 36.2% (95% CI: 29.1%-44.0%), 17.3% (95% CI: 13.6%-21.7%) and 15.4% (95% CI: 7.8%-27.9%), respectively. Stratified analyses showed that the prevalences of HPV were significantly higher in HIV-positive than HIV-negative MSM. The most frequent HPV high-risk type detected in the anus, penis and oral cavity was HPV-16 (19.9%, 4.9% and 3.1%, respectively). HPV infection is rising in MSM because of high-risk sexual behaviours, suggesting an increased future risk of developing HPV-related diseases and malignancies in this population.

[PMID: 32911499 PMCID: PMC7482923 DOI: 10.1371/journal.pone.0238564] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2019] [Accepted: 08/19/2020] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND The prevalence of human immunodeficiency virus (HIV) varies markedly among different risk groups in China, spreading fromhigh-risk populations to the general population. Indeed, China is in a critical period of HIV/acquired immunodeficiency syndrome (AIDS) prevention and control; however, data regarding HIV testing, infection and coinfection among infertile couples are lacking. This study aimed to estimate the HIV/AIDS prevalence to identify risk factors among infertile couples in Hunan, China. METHODS A cross-sectional hospital-based study was conducted to evaluate the prevalence of HIV/other infections (hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis, and Chlamydia trachomatis, Neisseria gonorrhoeae, and Mycoplasma genitalium (MG) infections) among 338,432 infertile individuals in Hunan, China, from 2012 to 2018. We calculated linear trends in prevalence using bivariate linear regression. RESULTS The overall prevalence rates of HIV, chlamydia, gonorrhea, MG, syphilis, and HBV and HCV antibody positivity in this study were 0.04%, 1.73%, 0.05%, 2.60%, 2.15%, 12.01% and 0.56%, respectively. The predominant infection was HBV, followed by MG, syphilis, and chlamydia. Only 1.13% of the participants (382/338432) reported sexually transmitted disease (STD) signs and symptoms suggesting genital tract infection. However, from 2012-2018, the variation in HIV prevalence was not significant (β = 0.000, PTREND = 0.907). The characteristics of the HIV-infected infertile population have not shifted dramatically, with women accounting for 32.56% of HIV cases in China. Overall, 87.60% of HIV-infected individuals have a relatively low education. In total, 37.98% of HIV-positive patients engage in high-risk behaviors. CONCLUSIONS This study expands upon existing knowledge of HIV prevalence in the infertile Chinese population. However, much work is needed to achieve popularization of prevention knowledge and change concept. Routine HIV screening is urgently needed for all adults with high-risk behaviors.

Abstract
Background Factory workers in low- and middle-income countries (LMICs) are vulnerable to HIV transmission. Interventions are needed to prevent HIV in this population. We systematically reviewed published literature on the efficacy of various HIV interventions in reducing stigma, risk behaviors and HIV transmission among factory workers. Methods A systematic review was performed using predefined inclusion and exclusion criteria. Four databases (PubMed, PsycINFO, Scopus and EMBASE) were searched for relevant publications between January 1, 1990 and December 31, 2018. Two independent reviewers assessed the methodological quality of studies. Results Thirteen articles were included, with 2 randomized controlled trials and 11 cohort studies. Five interventions and their combinations were summarized. Educational intervention increased condom use and reduced the use of recreational drugs and alcohol before sex. Community intervention that proactively provide HIV counselling and testing (HCT) services could increase the detection rate of HIV and other sexually transmitted diseases (STDs). Lottery intervention increased HCT uptake and decreased HIV public stigma. Education combined with community intervention reduced the proportion of workers with casual sex and enhanced HIV knowledge. Peer education combined with community intervention increased the proportion of workers who were willing to take their partners to HCT. Policy intervention combined with peer education enhanced HIV knowledge, perceived condom accessibility and condom use with regular partners. Conclusions Various interventions improved HIV knowledge, decreased HIV stigma and reduced HIV-related risk behaviors among factory workers in LMICs. The combination of multiple interventions tended to achieve better efficacy than a single intervention. Persistent combination interventions are essential to address HIV in this population.

Abstract
Men who have sex with men (MSM) attending university are a high-risk population for human papillomavirus (HPV) infection and are a neglected population of HPV vaccination programs in China. To provide evidence for HPV vaccination policies, we conducted this study to examine the prevalence and factors associated with anal HPV infection among MSM attending university in China. A self-administered online questionnaire was conducted to collect information on social demographics and sexual behaviors. A self-collected rectal swab specimen was collected to test for 37 HPV types. A total of 426 participants were tested for HPV. The median age was 20 years. HPV prevalence was 37.5% for any type, 29.8% for nine-valent vaccine types, 24.6% for four-valent vaccine types, 11.5% for HPV-16/18, and 15.7% for HPV-6/11. Men enrolled in a technical diploma, living in Northern China, having more than two sex partners, being bottom or versatile in anal sex, and having a human immunodeficiency virus (HIV) testing history were more likely to have positive anal HPV of any type. Our study found a high prevalence of anal HPV infection among MSM attending university in China, with HPV vaccine-preventable types being the most popular types in this group. Thus, our findings highlight the urgency of promoting HPV vaccination among teenage MSM.

Brief Report: Onward Transmission of Multiple HIV-1 Unique Recombinant Forms Among Men Who Have Sex With Men in Beijing, China. J Acquir Immune Defic Syndr 2019; 81:1-4. [PMID: 30768488 DOI: 10.1097/qai.0000000000001983] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
BACKGROUND Unique recombinant forms (URFs) were generated in dually infected or multiply infected individuals, and some of URFs can be transmitted to many people resulting in the emergence of circulating recombinant forms (CRFs). We examined whether there was evidence for onward transmission of multiple URFs among men who have sex with men (MSM) in Beijing. METHODS A total of 146 MSM subjects with acute/early HIV-1 infection were recruited from the Beijing PRIMO clinical cohort between September 2010 and July 2012. HIV-1 full-length gag and partial pol, env genes were amplified and sequenced separately. Phylogenetic analysis and recombination analysis were performed to determine the viral genotypes. Single genome amplification and direct sequencing were used to confirm onward transmission of URFs. RESULTS CRF01_AE was the most common genotype (51.9%), followed by CRF07_BC (23.0%), subtype B (14.8%), URFs (7.4%), CRF65_cpx (2.2%), and CRF55_01B (0.7%). Multiple forms of URFs were identified, including CRF01_AE/BC, CRF01_AE/B, and CRF01_AE/C. Nine of the 10 individuals harboring URFs were infected by onward transmission of URFs. The remaining one individual was coinfected with CRF01_AE and CRF07_BC variants. CONCLUSIONS We introduced a new method to provide evidence for onward transmission of URF strains by examining the absence of intersubtype coinfection among early infected individuals. Onward transmission of multiple URFs was found among MSM in Beijing, China. Our findings call for a program of continuous molecular surveillance and have implications to prevention programs among MSM in China.

Abstract
PURPOSE OF REVIEW To describe HIV epidemic and interventions for improving HIV continuum of care in China. RECENT FINDINGS The reported HIV epidemic has been continuously increasing, partially due to the expansion of active HIV testing campaign. Public health intervention programs have been effective in containing HIV spread among former plasma donors and people who inject drugs (PWID), but more infections occur among heterosexual men and women and young men who have sex with men. Of 1.25 million Chinese people are living with HIV, one-third do not know their status. About two-thirds of diagnosed individuals have used antiretroviral therapy (ART) and two-thirds of those on ART have achieved viral suppression, but some risk groups such as PWID have lower rates. The national free ART program has reduced adult and pediatric mortality and reduced heterosexual transmission. China faces great challenges to reduce HIV sexual transmission, improve the HIV continuum of care, and close the gaps to the UNAIDS Three "90" Targets.

Abstract
BACKGROUND The prevalence of HIV among men who have sex with men (MSM) has become a significant public health challenge. The aim was to comprehensively estimate the national prevalence of HIV among MSM and its time trends through a large-scale systematic analysis. METHODS Systematic search of Cochrane Library, PubMed, EMBASE, CNKI, VIP, and Wanfang Data databases without language restriction for studies on the prevalence of HIV among MSM published before Dec.31, 2018. Studies were eligible for inclusion if they were published in the peer-reviewed literature and used validated assessment methods to assess the prevalence of HIV among MSM. Estimates were pooled using random-effects analysis. RESULTS Data were extracted from 355 cross-sectional studies (571,328 individuals) covered 59 cities from 30 provinces and municipalities of China. The overall national prevalence of HIV among MSM from 2001 to 2018 was estimated to be 5.7% (95% CI: 5.4-6.1%), with high between-study heterogeneity (I2 = 98.0%, P < 0.001). Our study showed an increased tendency in the HIV prevalence as time progressed by meta-regression analysis (I2 = 95.9%, P < 0.0001). HIV prevalence was the highest in those aged 50 years and older with HIV prevalence of 19.3% (95%CI: 13.1-27.4%, N = 13). HIV was more prevalent in the illiterate population (16.8%), than in those who had received an education. Although the internet was a major venue for Chinese MSM seeking male sex partners (35.6, 95%CI: 32.3-39.9%, N = 101), seeking MSM in bathhouses/saunas had the highest associated prevalence of HIV (13.4, 95%CI: 10.3-17.1%, N = 22). The HIV prevalence among MSM varied by location: compared with other regions in China, HIV was highly prevalent among MSM in the southwest (10.7, 95%CI: 9.3-12.2%, N = 91). Compared to participants who sometimes or always used condoms, participants who had never used a condom in the past 6 months had a higher risk of HIV infection, with odds ratios of 0.1 (95%CI: 0.08-0.14). CONCLUSIONS Our analysis provided reliable estimates of China's HIV burden among MSM, which appears to present an increasing national public health challenge. Effective government responses are needed to address this challenge and include the implementation of HIV prevention.

Abstract
Men who have sex with men (MSM) are recommended to take up human papillomavirus (HPV) vaccination. There are concerns that MSM would increase sexual risk behaviors after taking up HPV vaccination, a phenomenon known as risk compensation. This study investigated the prevalence of and factors associated with behavioral intention to reduce the frequency of condom use with men after receiving the HPV vaccination. The study was based on the baseline sample of an ongoing randomized controlled trial promoting HPV vaccination among MSM in Hong Kong. Hong Kong Chinese-speaking MSM who have never vaccinated against HPV were recruited from multiple sources. A total of 624 participants completed the baseline survey during July to December 2017. The prevalence of behavior intention to reduce the frequency of condom use with regular and non-regular male sex partners after receiving HPV vaccination was 6.9% and 4.0%; 8.0% of them intended to reduce condom use with either type of male partners after receiving the HPV vaccination. Adjusting for significant background variables (education level and condomless anal intercourse with men in the last six months), two constructs of the pre-intentional phase of Health Action Process Approach model were significantly associated with the dependent variable in the expected direction. They were (1) positive outcome expectancies of condomless anal intercourse after receiving HPV vaccination (adjusted odds ratios [AOR]: 1.29, 95% confidence interval [CI]: 1.12, 1.48, p < 0.001) and (2) perceived self-efficacy of consistent condom use after receiving HPV vaccination (AOR: 0.83, 95% CI: 0.70, 0.92, p = 0.001). Risk compensation may not be a major concern when promoting HPV vaccination among MSM. The results should be assuring health-care providers and policymakers.

Background China faces a serious HIV epidemic among men who have sex with men (MSM), and a large proportion of new infections are attributed to their regular male sex partners (RP). The objective of this study was to investigate the association between intimate relationship characteristics and HIV-related behaviors among MSM with RP in Guangzhou, China. Methods A convenience-sampling method was used in data collection. A total of 608 MSM were screened, of whom 406 HIV negative MSM with at least one RP in the past six months were used for data analysis. Three-step logistic regressions were used to analyze the data. Results The prevalence of unprotected anal intercourse (UAI) with regular male sex partners, non-regular male sex partners, and concurrent UAI in the past six months was 53.9%, 23.6%, 20.7%, respectively. Variables associated with UAI with regular male sex partners included expectations for this relationship (adjusted odds ratio in multiple forward stepwise logistic regression, ORm = 1.66) and open communication about the sexual relationship (ORm = 1.79), while expectations for the relationship (ORm = 0.46 to 0.54) and conflicts of interest (ORm = 5.46 to 5.97) were associated with concurrent UAI and UAI with non-regular male sex partners. Conclusion Intimate relationship characteristics were related to HIV-related risk behaviors. Future HIV prevention interventions should take MSM couples into consideration, include a focus on the quality of their intimate relationships, and encourage open communication about their sexual relationships.

Abstract
BACKGROUND The HIV epidemic continues to expand among men who have sex with men (MSM) in China. The NIMH Project Accept/HPTN 043 trial suggested a borderline significant trend toward HIV incidence reduction among persons with higher testing rates. METHODS We assessed HIV testing histories and infection status among a community-based Beijing MSM. HIV serostatus was lab confirmed. We ascertained demographic/behavioral factors through questionnaire-based interviews. Associations of previous HIV testing with odds of current HIV infection were assessed, seeking improved like-with-like risk comparisons through multivariable logistic regression analysis with propensity score adjustment and restricted cubic spline modeling. RESULTS Among 3588 participants, 12.7% were HIV infected; 70.8% reported having ever tested for HIV. Compared with MSM who never tested, those ever testing had a 41% reduction in the odds of being HIV positive [adjusted odds ratio (aOR): 0.59; 95% confidence interval (CI): 0.48 to 0.74. Higher HIV testing frequencies were associated with a decreasing trend in the odds of being infected with HIV vs. a referent group with no previous testing [>6 tests (aOR: 0.27; 95% CI: 0.18 to 0.41); 4-6 (aOR: 0.55; 95% CI: 0.39 to 0.78); 2-3 (aOR: 0.61; 95% CI: 0.45 to 0.82); P for trend <0.001]. The multivariable-adjusted model with restricted cubic spline of HIV testing frequency showed a higher frequency of previous HIV testing associated with lower odds of HIV infection, particularly among men with ≥10 lifetime male sexual partners. CONCLUSIONS Using risk probability adjustments to enable less biased comparisons, frequent HIV testing was associated with a lower HIV odds among Chinese MSM.

Abstract
Grassroots non-governmental organizations (NGOs) played pivotal roles in HIV prevention among men who have sex with men (MSM) in China. Their governance and sustainability issues were under-studied. This nation-wide study surveyed leaders of 202 of the HIV related NGOs in China.58.4% of the leaders believed that their NGO would last for ≤5 years; which was negatively associated with perceived good relationship with CDC. 65.3% mentioned ≥3 non-sustainability issues; associated factors included perceived inadequacies in prevention skills, management skills, policy support, technical support, operational support, and CDC's support; a reverse association was found for frequent collaboration with organizations in China. 30.6% of the leaders mentioned ≥7 governance issues; a stepwise model found a positive association with having no office and negative associations with number of full-time staff and core volunteers. These problems would severely limit the effectiveness of HIV prevention among MSM. Related improvements and support are warranted.

Abstract
Background. The epidemiology of HPV in men who have sex with men (MSM) in Guangzhou, China, had not been reported previously. Methods. HIV-infected and HIV-uninfected MSM were recruited from a Guangzhou-based MSM clinic in 2013. Sociodemographic characteristics and sexual behaviors were collected. An anal cytological sample was taken for HPV testing. Results. We recruited 79 HIV-infected and 85 HIV-uninfected MSM. The median age was 26 years in both groups. The positivities of anal HPV of any type (81.0% versus 48.2%), any high risk type (50.6% versus 27.1%), any low risk type (55.7% versus 31.8%), and any 9-valent vaccine type (74.7% versus 36.5%) were all significantly higher among HIV-infected compared to that among HIV-negative MSM (p for all < 0.05). The great majority of HPV-infected MSM were infected with 9-valent vaccine types (59 out of 64 HIV-infected and 31 out of 41 HIV-uninfected). Anal bacterial infections were associated with higher anal HPV positivity and greater number of anal HPV types. Conclusion. Sexually active MSM in Guangzhou, especially those infected with HIV, had high and multiple HPV detections. The majority of these cases were potentially preventable by HPV vaccine. Regular anal exams and early HPV vaccination are warranted in this population.

Abstract
We performed a systematic review to estimate the proportion of men who have sex with men (MSM) in Asia who are bisexual and compare prevalence of HIV and sexual risk between men who have sex with men and women (MSMW) and men who have sex with men only (MSMO). Forty-eight articles based on 55 unique samples were identified from nine countries in Asia. Bisexual behaviour was common among MSM (pooled prevalence 32.8 %). Prevalence of HIV (pooled OR 0.90; 95 % CI 0.77-1.05), recent syphilis infection (pooled OR 0.99; 95 % CI 0.93-1.06) and unprotected anal intercourse (pooled OR 0.80; 95 % CI 0.57-1.11) were similar between MSMW and MSMO, but heterogeneity was high. MSMW had lower odds of reporting a prior HIV test than MSMO (OR 0.82; 95 % CI 0.70-0.95; p = 0.01, I(2) = 0 %). Targeted interventions are needed to increase uptake of HIV testing among MSMW. Increased reporting of disaggregated data in surveillance and research will help improve understanding of risk in MSMW and inform targeted interventions.

Abstract
High risk MSM are recommended to take up HIV voluntary counseling and testing (VCT) once every 6 months. 809 HIV-negative MSM in Beijing, China entered the 18-month prospective cohort study; 228 joined an extended study at month 21. The majority (92.5 %) of the participants had taken up four rounds of VCT over the study period. HIV prevalence at months 0, 6, 12, 18 and 21 ranged from 2.5 to 6.3 %; HIV incidences for the four intervals between the five visits ranged from 5.00 to 14.28 per 100-person year. Despite experiencing repeated VCT, high levels of risk behaviors were reported at month 21. 18 % of the participants interviewed at month 21 self-reported increased in UAI and other risk behaviors, comparing recent and pre-baseline experiences. HIV transmission and risk behaviors had not been reduced by multiple rounds of VCT. Reasons behind apparent ineffectiveness and tailored repeated testing strategies need to be investigated.

Abstract
High HIV prevalence and incidence burdens have been reported in men who have sex with men (MSM) in Chongqing, China. We aimed to estimate the prevalence of HIV and other sexually transmitted infections (STIs), to appraise the knowledge and risk behaviors related to HIV/AIDS among MSM, and to analyze the possible causes of deviation between behavior and knowledge to make better strategies. We recruited 617 MSM from February to July in 2008 by using a respondent-driven sampling (RDS) method in Chongqing, China. Through the collection of questionnaire-based data and biological testing results from all objects, we launched a cross-sectional survey. STATA/SE was used for data analysis by frequency, ANOVA, rank sum test and logistic regression models. MSM with syphilis (OR=4.16, 95%CI: 2.35-7.33, P<0.0001) were more likely to be HIV infected. Being a company employee (OR=3.64, 95%CI: 1.22-10.08, P<0.0001) and having bought male for sex (OR=3.52, 95%CI: 1.10-11.32, P < 0.034) were associated with a higher probability of syphilis. MSM with younger age, higher education and greater monthly income had a higher mean knowledge score. MSM who had HIV testing had a higher mean knowledge score than those who never had. Students, venues for finding sex partners by Internet and homosexuals in MSM had a higher mean knowledge score compared to other occupations, venues for finding sex partners and sexual orientation. There is an urgent need for delivery of barrier and biomedical interventions with coordinated behavioral and structural strategies to improve the effect of HIV interventions among MSM.

Abstract
Background Anal human papillomavirus (HPV) infection and its related diseases are relatively common in men who have sex with men (MSM), especially in those HIV positive. In China, molecular epidemiology of anal HPV infection among HIV-positive MSM has been sparsely studied. Methods A cross-sectional study was conducted among HIV-positive MSM in Xi’an, China between April and July 2014. Anal swabs were collected for HPV genotyping. Results A total of 195 HIV-positive MSM were included in this study. HPV genotyping showed that 99.0% (191/193) of participants were positive for at least one of the targeted 37 HPV genotypes. 183 (94.8%) of them were infected with multiple high-risk types and 154 (79.8%) of them with low-risk HPV types. HPV 18 was the most frequently identified high-risk type, followed by HPV 16 and HPV 51. As for low-risk types, HPV11, HPV 6 and HPV 81 were most commonly observe. High-risk HPV infection was found to be associated with the status of antiretroviral therapy (ART), the distribution of low-risk types was observed to be varied by CD4+ T cell level. Conclusion Almost all HIV-positive MSM were anal HPV infected in our study. It is highly recommended to consider regular active screening and preventive intervention of HPV infection among this high risk population.

Abstract
The HIV prevalence and incidence among men who have sex with men (MSM) in China are high. Unprotected anal intercourse (UAI) with a regular male sex partner (RP), a significant predictor of HIV sero-conversion, was high yet under-emphasized among MSM having RP (MSMRP). The present cross-sectional survey interviewed 307 HIV negative MSMRP recruited through convenient sampling from multiple sources, including venue-based outreaching, online recruitment, and referrals made by peers, in Beijing and Chengdu, China. Among MSMRP, the prevalence of UAI with RP in the last three months was 52.4%. The results of the multivariate analysis showed that trust and intimacy within the relationship with RP and presence of clinical depression symptoms were positively associated with UAI with RP in the last three months. Other associated scalar factors derived from the Theory of Planned Behavior were related to perceptions on condom use, including positive attitudes toward condom use (a negative association), subjective norm of the perception that MSM do not usually use condoms during anal intercourse with RP (a positive association), perceived behavioral control over condom use with RP (a negative association), and behavioral intention to use condoms with RP in the coming three months (a negative association). It is seen that MSMRP were at high risk of HIV/STD transmission. The associated factors hence involved those related to perceptions about condom use, mental health, and interpersonal relationship. Future interventions should take these multi-dimensional factors into account. In particular, future research to test the efficacy of couple-based interventions that include mental health elements needs to be conducted, as trust and intimacy within the relationship were associated with UAI among MSMRP, and mental health problems may exist for both the MSMRP and their RP.

Abstract
Bisexual men (men who have sex with men and women) are potential epidemiological bridges responsible for the spread of HIV and other sexually transmitted infections from men who have sex with men only to the heterosexual population. We aimed to estimate the prevalence of syphilis and HIV and the factors associated with syphilis infection among men who have sex with men and women and men who have sex with men only from Shijiazhuang, China. In 2011-2013, a cross-sectional cohort of 427 men who have sex with men was recruited by a snowball sampling method and tested for syphilis and HIV. Chi square and logistic regression were performed to identify syphilis risk factors. Among the 427 men who have sex with men, 71 (16.6%) cases were syphilis-positive and 16 cases (3.7%) were HIV-positive. The proportions of men who have sex with men and women and men who have sex with men only in the total sample were 31.4% and 68.6%, respectively. Men who have sex with men and women exhibited double the syphilis prevalence of men who have sex with men only and were more likely to practice insertive anal sex. Higher education level, being married, having more male partners, and both receptive and insertive anal sex roles were associated with syphilis among men who have sex with men and women. Residing in suburban areas, being married, being HIV positive, and an absence of desire to change sexual orientation were associated with syphilis among men who have sex with men only. Therefore, men who have sex with men and women represent an important sub-group in the syphilis epidemic and further interventions should be developed to reduce risk among different sub-sets of men who have sex with men.

Abstract
Background An increasing incidence of anal cancer among men, especially men who have sex with men (MSM) suggests a need to better understand anal human papillomavirus (HPV) infection among this group. Methods A cross-sectional study was conducted among MSM in Shenzhen, China. Blood was collected for HIV serological testing and syphilis serological screening, and anal swabs were collected for HPV genotyping. Difference of HPV prevalence between HIV seropositive and HIV seronegative MSM was assessed by chi-square test. Factors associated with anal canal HPV infection were assessed by univariate and multivariate logistic regression. Results A total of 408 MSM were recruited. HIV and HPV prevalence were 6.9% and 36.4%, respectively. HPV was detected in the anal canal in 71.4% of the HIV-positive MSM and in 33.8% of the HIV-negative MSM (P<0.001). Oncogenic types were seen more often in anal specimens of HIV-positive MSM than in specimens of HIV-negative MSM (P = 0.001). The HPV genotypes detected most frequently were HPV06 (8.2%), HPV16 (7.2%), HPV11 (6.4%), HPV18 (4.7%), HPV58 (4.7%), and HPV52 (4.2%). Conclusions In this study, HIV positive MSM had a higher burden of HPV infection, especially oncogenic HPV infection. HPV types 52 and 58 were as popular as those types designed for the currently available vaccine (HPV6, 11, 16, 18).

ARCHIVES OF SEXUAL BEHAVIOR 2014; 43:789-800. [PMID: 23982568 DOI: 10.1007/s10508-013-0172-3] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/19/2012] [Revised: 11/20/2012] [Accepted: 12/29/2012] [Indexed: 06/02/2023]
Abstract
The prevalence of HIV and HPV is high among men who have sex with men (MSM) in China. It is unclear whether cognitive and affective responses related to HPV and HPV-related diseases are negatively associated with HIV-related risk behaviors among MSM. This cross-sectional study interviewed 449 adult Chinese MSM in Hong Kong. The prevalence of unprotected anal intercourse (UAI) and having had anal sex with more than one man in the last 6 months (multiple male sex partnerships) was 39.0 and 71.3 %, respectively. After adjusting for four significant background variables (education level, cohabitation with a man, exposure to HIV prevention materials, and HIV voluntary counseling and testing), variables negatively associated with UAI and/or multiple male sex partnerships included (1) correct HPV-related knowledge (AOR = 0.48-0.66), (2) perceived susceptibility (AOR = 0.32-0.55) and perceived severity (AOR = 0.12-0.60) related to HPV and HPV-related diseases, and (3) fear towards contracting genital warts and penile/anal cancer (AOR = 0.40-0.55). Perceived high chance of contracting HPV was positively associated with multiple partnerships (AOR = 4.74). It is possible to reduce HIV-related risk behaviors by increasing levels of knowledge, cognitions, and fear related to HPV and related diseases. It is important to integrate prevention of HIV with prevention of sexually transmitted infections. Such interventions are warranted.

Abstract
Objectives. To figure out the most current prevalence of HIV and syphilis in MSM in China. Methods. A meta-analysis was conducted on the studies searched through PubMed, CNKI, and Wanfang published between 1 January 2009 and 11 April 2013. Results. Eighty-four eligible studies, either in Chinese or in English, were included in this review. The pooled prevalence of HIV and syphilis infection in MSM in China was 6.5% and 11.2%, respectively. The subgroup analyses indicated that the prevalence of HIV infection was higher in the economically less developed cities than that in the developed cities (7.5% versus 6.1%, P < 0.05). In contrast, the prevalence of syphilis infection was lower in less developed cities than in developed cities (8.6% versus 15.1%). Studies with a sample size smaller than 500 had a lower prevalence of HIV and syphilis infection than those with a sample size greater than 500 (5.9% versus 7.2% for HIV; 11.0% versus 11.5% for syphilis, respectively). Conclusions. HIV and syphilis infection are prevalent in MSM in China. The different prevalence of HIV and syphilis infection between developing and developed cities underscores the need to target prevention strategies based on economic conditions.

Abstract
The growing HIV/AIDS epidemic in China appears to be related to the vast rural-to-urban migration, with rural migrants serving as a “living bridge” for the spread of HIV. The purpose of this study is to examine whether migrants' wives remaining in rural homes play a role in spreading the virus. Participants were recruited from 12 rural villages. Social and demographic factors, sexual behaviour, and HIV/AIDS knowledge were assessed using survey questionnaire. Reproductive tract infection (RTI; syphilis, chlamydia, gonorrhea, vaginalis trichomonas, and candidiasis) were assessed using blood and vaginal specimens. Among the total 63 participants, 28 (44.4%) were wives remaining behind while their husbands migrated to a city (“remaining”) and 35 were women whose spouses remained in the rural setting (“comparison”). The reported median duration (inter-quarter range (IQR)) since the last episode of sex with husband was nine months (IQR: 7–15) for the remaining women and three months (IQR: 2–7) for the comparison women (Z = 3.95, p < 0.01). RTI was 32.1% for remaining women and 17.1% for the comparison women (Odds ratio = 2.28, 95%CI: 0.70–7.48, p = 0.165). The high rate of RTI suggests that remaining women in rural areas may be at increased risk for acquiring HIV infection compared to women whose husbands remained in rural homes.

Abstract
This study was conducted to examine the prevalence of syphilis among blood donors in the Xi'an region of China. All blood donors were unremunerated volunteers recruited from 2006 to 2010. Anti-Treponema pallidum and anti-HIV serology responses were determined using ELISA kits. Among 159 902 voluntary blood donors tested, a total of 575 syphilis (0.36%) and 55 HIV (0.03%) infections were identified. While an increasing trend was shown for the prevalence of both syphilis and HIV over the 5-year period, there was no statistical correlation between the two infections. Our results indicate that syphilis and HIV infections are increasing risk factors for the spread of blood-borne infections. Further investigations and improvements in blood collection and testing procedures are needed to help ensure the safety of donated blood in China.

Abstract
BACKGROUND In light of China's unique ethnic and sociocultural context, and a marked rise in HIV prevalence among MSM, it is important to determine prevalence, genotypes and predictors of anal human papillomavirus (HPV) among HIV-infected and uninfected men who have sex with men (MSM) in Beijing, China. METHODS In 2010-2011, we recruited MSM (age range 18-61; median 28 years) through peer volunteers, and collected demographic/behavioral information via interviewer-administrated questionnaires. Trained health workers collected anal swabs for HPV genotyping by PCR and blood samples for HIV/syphilis serologies. RESULTS We obtained anal specimens from 212 HIV-infected and 459 HIV-uninfected participants. Among HIV-infected MSM, 82.1% were HPV-infected vs. 57.5% in HIV-uninfected (p<0.01). HIV-infected men had the greatest likelihood of multiple types: 17.9% uninfected; 36.3% with one type; 36.8% with 2-3; 9.0% with ≥4. Oncogenic HPV prevalence was higher among HIV- infected (61.3%) than uninfected participants (39.7%; p<0.01). HIV-uninfected MSM reporting always using condoms during insertive anal intercourse (past 6 months) were less likely to be HPV-infected (OR=0.49, 95%CI: 0.31-0.77). Among HIV-uninfected MSM, HPV infection was associated with unprotected receptive anal intercourse (past 6 months; OR=1.92, 95%CI: 1.19-3.11) and being forced to have sex (previous year; OR=3.32, 95%CI: 1.10-10.0). Multivariable logistic analysis among HIV infected MSM suggested that unprotected oral intercourse (past 6 months) was associated with HPV (adjusted OR=2.12, 95%CI: 1.00-4.48). Syphilis occurred in 55.8% of HIV-infected/HPV-infected, 50.0% of HIV-infected/HPV-uninfected, 19.6% of HIV-uninfected/HPV-infected, and 13.0% of HIV-uninfected/HPV-uninfected MSM. CONCLUSIONS HPV anal infections were more common among HIV-infected than uninfected MSM in China, including oncogenic and multiple types. Unprotected oral and receptive anal sex were was independently associated with HPV infection. Promotion of safer sex and HPV vaccination is strongly recommended among MSM.

Abstract
Men who have sex with men (MSM) are at high risk of contracting HIV and developing genital warts and penile/anal cancers. HPV vaccines are efficacious in preventing such HPV-related diseases among males and WHO recommends its use to young MSM. In a cross-sectional survey, 542 MSM were interviewed. After being briefed about the vaccines' efficacies and the market price, the prevalence of acceptability of HPV vaccination was 29.2%. Adjusted by significant background variables, perceived high/very high chances of contracting genital warts [adjusted odds ratio (AOR)=2.04, 95%CI=1.11-3.72] and penile/anal cancers (AOR=1.89, 95%CI=1.09-3.29) among local MSM, perceived moderately high mortality rate of penile/anal cancers (AOR=1.78, 95%CI=1.13-2.81), fear toward penile/anal cancers (moderate: AOR=1.75, 95%CI=1.07-2.86; high/very high: AOR=1.82, 95%CI=1.13-2.92) and disagreement with the statement "MSM in general are not willing to take HPV vaccines" (AOR=1.82, 95%CI=1.24-2.68) were associated with the conditional acceptability. Acceptability of this new measure is reasonably high and there are rooms for improvement. Implementation trials to promote HPV vaccination by changing cognitions such as HPV-related risk perceptions, norms and perceptions toward anal/penile cancer are greatly warranted.

Abstract
Human Papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) worldwide. Incidence rates of HPV infection among human immunodeficiency virus (HIV)-infected individuals are well documented and are several-fold higher than among HIV-uninfected individuals. Few studies have demonstrated an increased risk for acquiring HIV infection in those with HPV infection, and this risk seems to be higher when HPV strains are of high-risk oncogenic potential. The estimated prevalence of high-risk oncogenic HPV infection is highest in men who have sex with men (MSM), a particularly vulnerable group with high prevalence rates of HIV infection and other STIs. In this paper, we provide a comprehensive review of the available literature on the role of HPV infection in HIV acquisition. Our review includes data from cross-sectional and longitudinal studies.
