Liu J, Liu S, Yu S, Du X, Hao J, Hui R, Buh A, Chen W, Chen J. Willingness to receive mpox vaccine among men who have sex with men: a systematic review and meta-analysis. BMC Public Health 2024; 24:1878. [PMID: 39010029 PMCID: PMC11247826 DOI: 10.1186/s12889-024-19260-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Accepted: 06/25/2024] [Indexed: 07/17/2024] Open
Abstract
BACKGROUND Since May 2022, mpox outbreaks have been occurring in non-mpox endemic areas, with the main population affected being men who have sex with men (MSM). Outbreak prevention and control depend not only on the effectiveness of vaccines but also on people's willingness to receive these vaccines. Currently, there is lack of synthesis on the overall rates and influence factors of MSMs' willingness to vaccinate against mpox. Therefore, we systematically reviewed studies that assessed the willingness of MSM to receive mpox vaccine. METHODS Studies reporting mpox vaccination intentions among MSM were included by searching five databases (PubMed, Web of Science, EMBASE, CINAHL, and SCOPUS) from inception to May 12, 2024. The quality of the included literature was assessed using Joanna Briggs Institute's critical appraisal tool. The data analysis software is Stata17. The systematic review has been registered with Prospero (registration ID: CRD42023452357). RESULTS Twenty cross-sectional studies were included in the review. Meta-analysis results showed that the pooled willingness rate of vaccinate against mpox was 77.0% (95% CI: 73-81%, I2 = 99.4%). According to subgroup analysis, study countries (P = 0.002), research sample size (P = 0.001), and whether participants were infected with HIV (P = 0.002) may be sources of heterogeneity. The results of the meta-analysis of influencing factors showed that more number of sexual partners (OR: 2.24, 95%CI: 1.86-2.69), pre-exposure prophylaxis use (OR: 6.04, 95%CI: 4.80-7.61), history of sexually transmitted infections (OR: 2.96, 95%CI: 2.33-3.76), confidence in the vaccine's effectiveness (OR: 2.79, 95%CI: 2.04-3.80) and safety (OR: 10.89, 95%CI: 5.22-22.72), fear of mpox infection (OR: 2.47, 95%CI: 2.11-2.89) and epidemics (OR: 2.87, 95%CI: 2.22-3.70), high mpox knowledge (OR: 2.35, 95%CI: 1.51-3.66), and the belief that people at high risk should be prioritized for vaccination (OR: 3.09, 95%CI: 1.40-6.84) were the facilitators of vaccine willingness. In addition, as a secondary outcome, meta-analysis results showed a pooled unwillingness rate of 16% (95% CI: 13-20%, I2 = 98.1%, 9 studies). CONCLUSION Willingness to vaccinate mpox was high among MSM, but some participants still had negative attitudes towards vaccination. Therefore, the Ministry of Public Health should develop targeted and effective strategies against those influencing factors to prevent and manage mpox outbreaks.

Abstract
The methodological issues of using self-reported human immunodeficiency virus (HIV) testing history to determine HIV infection status are understudied. This study aimed to assess the disparities between HIV testing history and self-reported HIV status, with a specific objective of estimating the prevalence of self-reported HIV-negative status in sexually active students who had never had an HIV test (inaccurate self-disclosure). Participants were recruited from four Hong Kong universities; 255 students were included in the analysis, with 16.1% of participants being men who have sex with men (MSM). Overall, 81.6% of participants reported they never had been tested for HIV, with inaccurate self-disclosure by 65.9% of participants. Among participants who used condoms inconsistently, only 20.2% had had HIV tests, with inaccurate self-disclosure by 66.7% of subjects. Among MSM students, only 36.6% had had HIV tests, with inaccurate self-disclosure by 61.0% of participants. Among MSM students who used condoms inconsistently, only 35.1% had had HIV tests, with inaccurate self-disclosure by 62.2% of participants. The findings raise concerns about the use of self-reported HIV status in clinical practice and research. The low prevalence of HIV testing found suggests that interventions to promote HIV testing should be continued.

Abstract
A scoping literature review to identify the multilevel HIV serosorting related elements was developed. Articles from EBSCO, PubMed, PsyNET and Science Direct with serosort* or serosorting at the tittle or abstract, written in English or Spanish were included. No restriction in type of population or design were applied. 239 records were retrieved after duplicates removed, but 181 references were extracted for full-text review. Individual level: HIV knowledge, serostatus, risk perceptions, abilities to disclose and for condom use negotiation, motivations, use of drugs, stigma, attitudes toward condom use, and perceptions/beliefs about the HIV and related treatments, HIV infection rates/testing and behavioral factors. Interpersonal level: social networks, abilities (sexual behavior negotiation, and communication). Community level: stigma, social norms, access to HIV related services. Structural level: political context, HIV related funding and public policies. HIV Serosorting is not solely an interpersonal behavior it involves multilevel elements that must be acknowledged by professionals and stakeholders.

Bacterial sexually transmitted infections among HIV-infected patients in the United States: estimates from the Medical Monitoring Project. Sex Transm Dis 2015; 42:171-9.

Abstract
BACKGROUND Bacterial sexually transmitted infections may facilitate HIV transmission. Bacterial sexually transmitted infection testing is recommended for sexually active HIV-infected patients annually and more frequently for those at elevated sexual risk. We estimated percentages of HIV-infected patients in the United States receiving at least one syphilis, gonorrhea, or chlamydia test, and repeat (≥2 tests, ≥3 months apart) tests for any of these sexually transmitted infections from mid-2008 through mid-2010. DESIGN The Medical Monitoring Project collects behavioral and clinical characteristics of HIV-infected adults receiving medical care in the United States using nationally representative sampling. METHODS Sexual activity included self-reported oral, vaginal, or anal sex in the past 12 months. Participants reporting more than 1 sexual partner or illicit drug use before/during sex in the past year were classified as having elevated sexual risk. Among participants with only 1 sex partner and no drug use before/during sex, those reporting consistent condom use were classified as low risk; those reporting sex without a condom (or for whom this was unknown) were classified as at elevated sexual risk only if they considered their sex partner to be a casual partner, or if their partner was HIV-negative or partner HIV status was unknown. Bacterial sexually transmitted infection testing was ascertained through medical record abstraction. RESULTS Among sexually active patients, 55% were tested at least once in 12 months for syphilis, whereas 23% and 24% received at least one gonorrhea and chlamydia test, respectively. Syphilis testing did not vary by sex/sexual orientation. Receipt of at least 3 CD4+ T-lymphocyte cell counts and/or HIV viral load tests in 12 months was associated with syphilis testing in men who have sex with men (MSM), men who have sex with women only, and women. Chlamydia testing was significantly higher in sexually active women (30%) compared with men who have sex with women only (19%), but not compared with MSM (22%). Forty-six percent of MSM were at elevated sexual risk; 26% of these MSM received repeat syphilis testing, whereas repeat testing for gonorrhea and chlamydia was only 7% for each infection. CONCLUSIONS Bacterial sexually transmitted infection testing among sexually active HIV-infected patients was low, particularly for those at elevated sexual risk. Patient encounters in which CD4+ T-lymphocyte cell counts and/or HIV viral load testing occurs present opportunities for increased bacterial sexually transmitted infection testing.

Abstract
African-American women with HIV are among the fastest growing populations with HIV. The psychosocial factors and beliefs/attitudes associated with disclosure and other un-safe sex practices are not fully understood in this population. A total of 158 HIV-positive women receiving primary care in an HIV clinic in Philadelphia who enrolled in a safe-sex intervention, completed a baseline questionnaire on their sexual activities with male partners and psychosocial factors that were potential protective/risk factors for unsafe sex. Women who were emotionally close and monogamous with their partner were most likely to disclose their HIV status and least likely to worry they had infected their partner. Women who were non-monogamous and who did not have an emotional connection to any of their partners were least likely to self-disclose. Partners were more likely to know each other's status when the woman felt she had a responsibility to talk about the importance of staying HIV-negative.

Abstract
The practice of unprotected anal intercourse (UAI) involves at least two partners. We examined the associations between insertive or receptive UAI and perceived HIV seroconcordance and partnership type in self-perceived HIV-negative and self-perceived HIV-positive men who have sex with men (MSM). MSM (age ≥ 18 years) were recruited for a cross-sectional survey at the sexually transmitted infections clinic in Amsterdam, the Netherlands, in 2008-2009. Participants completed a questionnaire concerning partnerships in the preceding 6 months. Associations were quantified via multinomial logistic regression models using generalized estimating equations. The outcomes were 'no, or safe anal intercourse', 'insertive UAI', and 'receptive UAI'. We included 5,456 partnerships from 1,890 self-perceived HIV-negative men and 1,861 partnerships from 558 self-perceived HIV-positive men. Within the partnerships, perceived HIV status of the partner was an important determinant of UAI (p < 0.001). Among HIV-negative men, perceived HIV discordance was negatively associated with receptive UAI compared with no or safe UAI (OR 0.57; 95 % CI 0.36-0.92); when the partners were more familiar with each other, the risk of receptive UAI was increased relative to no or safe anal intercourse. Among HIV-positive men, perceived HIV discordance was negatively associated with insertive UAI (OR 0.05; 95 % CI 0.03-0.08). Within partnerships, perceived HIV status of the partner was one of the strongest determinants of UAI among self-perceived HIV-negative and HIV-positive MSM, and discordant serostatus was negatively associated with UAI. The findings suggest that serosorting is one of the main strategies when engaging in UAI.

Abstract
In recent years, guidelines for HIV treatment have recommended initiation of combination antiretroviral therapy (cART) earlier in the course of the disease than was previously the case. These recommendations stem in part from growing evidence that treatment reduces the risk of sexual transmission. We used an epidemiological model of disease transmission and progression to assess HIV prevention through early treatment-that is, initiation of cART when CD4 white blood cell counts are in excess of 350 cells per cubic millimeter. (CD4 cells are involved in the immune system's defense against tumors and infection; the number of CD4 cells in a cubic millimeter of blood is a standard measure of immune response to antiretroviral therapy.) We estimated that the actual timing of treatment initiation in the United States prevented 188,000 HIV cases in the period 1996-2009. "Very early" treatment (at CD4 counts greater than 500) accounted for four-fifths of the prevented cases. For all of the prevented cases, the losses in life expectancy that were avoided were worth $128 billion, assuming that a life-year has a value of $150,000. These findings underscore the cost-effectiveness of early HIV treatment.

Abstract
BACKGROUND Most persons diagnosed as having HIV alter their sexual behavior in a way that reduces the risk of HIV transmission, but the durability of such behavior change is unknown. METHODS We conducted annual anonymous cross-sectional surveys in randomly selected patients with appointments at a large, public hospital HIV clinic in Seattle, Washington, from 2005 to 2009. We used logistic regression to assess the association between time since HIV diagnosis and self-report of unprotected anal or vaginal intercourse (UAVI) with partners of negative or unknown HIV status (nonconcordant UAVI), and quantile regression to evaluate the association between time since HIV diagnosis and number of anal or vaginal sex partners. RESULTS We analyzed 845 surveys collected for 5 years. Men who have sex with men (MSM) had been diagnosed as having HIV a mean (standard deviation) of 12 (7) years and non-MSM a mean of 11 (6) years. Among 597 MSM, longer time since HIV diagnosis was associated with lower age-adjusted odds of reporting nonconcordant UAVI (odds ratio, 0.96 [95% confidence interval, 0.92-0.99]) and a lower age-adjusted number of sex partners (β coefficient = -0.03, P = 0.007). Among 248 women and heterosexual men, time since HIV diagnosis was not significantly associated with age-adjusted odds of nonconcordant UAVI (odds ratio 0.99 [95% confidence interval, 0.93-1.04]) or number of sex partners (β coefficient = -0.01, P = 0.48). CONCLUSIONS These results indicate that HIV transmission-associated behavior is relatively stable following the first year after HIV diagnosis. Our findings suggest that behavior change in the first year after HIV diagnosis, reported in other studies, is durable.

Abstract
We assessed sexually transmitted infection risk behaviours and desire to discuss mental health, as reported by 426 HIV-infected men who have sex with men receiving HIV care in eight urban clinics. Most of these patients (90%) had begun HIV care >1 year ago. In the past year, 74% had multiple sexual partners, 75% engaged in anal intercourse, 48% had >1 HIV-uninfected partner and 82% used illegal psychoactive drugs. Among those reporting anal intercourse, approximately 61% reported using a condom during the most recent episode. Among all patients, 70% wanted to talk with their clinicians about how they felt mentally or emotionally. Using a two-tailed chi-squared test, we found that patients who engaged in unprotected receptive anal sex were more likely to want such a conversation than those who did not (80% versus 62%, P < 0.01); and those who engaged in unprotected insertive anal sex were also more likely to want such a conversation (81% versus 63%, P < 0.01). The findings highlight the prevalence of risky sexual behaviour and of mental health concerns in the participating patient population. Patients reporting risky sexual behaviour were more likely to want to discuss how they felt mentally or emotionally than those not reporting such behaviour.

Abstract
Understanding the experiences of youth living with HIV (YLH) is necessary for implementing interventions that mitigate HIV transmission. We conducted a survey of sexual behaviours and sources of knowledge among 107 youths aged 16-24 attending two HIV clinics in Kigali, Rwanda. Respondents were 72% women and 28% men, with median age 18 years. Of those sexually active in the past six months, 56% reported inconsistent condom use; 53% of sexually active respondents reported having sexually transmitted infection (STI) symptoms in the past six months. The median age difference between respondent and first sex partner was nine years for women, and 0.5 years for men (P = 0.006). Women more frequently reported being forced to have sex (29% girls versus 6.5% boys, P = 0.011) and exchanging sex for money (66% girls versus. 17% boys, P = 0.033). Strengthening female YLH's financial and material resources may reduce the number of sexual partners, asymmetries within partnerships and risk of HIV transmission.

Abstract
To investigate factors associated with online sex-seeking behaviors among men who have sex with men (MSM) in Beijing, China. MSM participants were recruited from two cohort studies with multiple enrollment methods from November 2006 to February 2007 and from March to June 2008, respectively. Data collected included demographics and sexual behaviors. Of the 901 participants, 68.1% were single; 69.3% were non-Beijing residents; 94.4% considered themselves to be homosexual; 65.2% received college or higher levels of education; the median age was 26 years; 73.0% sought male sex partners via the Internet in the past 3 months; 66.2% had ≥2 sex partners. Younger age, higher levels of education and having had ≥2 male sex partners in the past 3 months were independently associated with seeking sex partners on the Internet. These findings indicate that Internet-based intervention programs could encourage younger high-risk MSM to use condoms and reduce their numbers of sexual partners.

Abstract
OBJECTIVE This study examines factors associated with the acceptability of receiving sexually transmitted disease (STD) laboratory results by text message and e-mail among clinic attendees. SUBJECTS AND METHODS An anonymous self-administered survey was conducted with a convenience sample of STD clinic attendees in South Carolina and Mississippi in 2009-2010. In total, 2,719 individuals with a median age of 26 years (interquartile range, 21-32 years) completed the survey. RESULTS More than 70% had Internet access at home, and 80% reported using text messaging daily. Participants preferred receiving laboratory results by text message compared with e-mail (50.2% versus 42.3%; p<0.001). Acceptability of receiving laboratory results by text message was higher with younger age (adjusted odds ratio [aOR] 1.13; 95% confidence interval [CI] 1.10-1.26), daily use of text messaging (aOR 1.30; 95% CI 1.14-1.49), and reporting cell phone and text message as the preferred choice of regular communication with the clinic (aOR 2.31; 95% CI 1.50-3.58) and was significantly lower in female subjects (aOR 0.89; 95% CI 0.81-0.98) and those with college-level education (aOR 0.88; 95% CI 0.77-0.99). CONCLUSIONS A majority of STD clinic attendees have access to cell phones and Internet. The acceptability of receiving STD laboratory results electronically may facilitate test result delivery to patients and expedite treatment of infected individuals.

Abstract
OBJECTIVES Unprotected sexual intercourse between men who have sex with men (MSM) is the most common route of HIV infection in Germany. Approximately 70% of newly infected people are MSM. Substance use is a determinant of sexual risk behaviour in the general population, but also in the MSM subpopulation. There are only a few studies, from the USA, on the correlation between substance use and sexual risk behaviour in HIV-infected MSM in specialized care. METHODS In a German sample of 445 HIV-infected MSM treated in specialized out-patient clinics, the influence of substance use on sexual risk behaviour was investigated. Information was obtained from subjects using self-report questionnaires and a structured interview. RESULTS Recreational drug use was common. The prevalences of cannabis addiction (4.5%), harmful use of cannabis (4.3%) and harmful use of dissociative anaesthetics (0.4%) were higher than in the general German male population. A substantial proportion of patients reported unprotected insertive (32.9%) and receptive (34.6%) anal intercourse during the last 12 months. Use of cannabis, amyl nitrite, dissociative anaesthetics, cocaine, amphetamines and erectile dysfunction medication was significantly correlated with unprotected sexual contacts. Substance use in the context of sexual activity significantly increased sexual risk behaviour. CONCLUSIONS Substance use, especially in the context of sexual activity, should be taken into account when developing new prevention and intervention programmes aimed at reducing sexual risk behaviour in HIV-infected MSM currently in specialized care.

Abstract
PURPOSE OF REVIEW To highlight the latest developments in mathematical transmission modelling of HIV epidemics among men who have sex with men (MSM) and people who inject drugs (PWID). RECENT FINDINGS Mathematical approaches have been applied to a wide range of topics in recent HIV research. Epidemiological models have evaluated past and forecasted future trends in prevalence and incidence, evaluated innovative behaviour modification strategies and public health programmes aimed at minimizing risk, and explored the potential impact of various biomedical interventions. MSM have developed new risk reduction strategies which models have deemed to be effective at a population level only in certain settings, such as when there are high rates of HIV testing. Modelling has also indicated that persistent circulation of drug-resistant HIV strains is likely to become an inevitable public health issue in the near future in resource-rich settings among MSM. Models have also recently been used to demonstrate that needle and syringe programmes for harm reduction among PWID are effective and cost-effective. SUMMARY Mathematical modelling is particularly amenable to single population groups of concentrated HIV epidemics, such as among MSM and PWID. Models have been utilized to evaluate innovative areas in clinical, biomedical and public health research that cannot be conducted in other population groups. Future directions are likely to include evaluation of specific public health programmes and providing understanding of the importance of specific treatment regimens and incidence and interaction of comorbid conditions associated with HIV.

Abstract
In July 2010, the Obama Administration released a National HIV/AIDS Strategy for the United States to refocus national attention on responding to the domestic HIV epidemic. The goals of the strategy are to reduce HIV incidence; to increase access to care and optimize health outcomes among people living with HIV; and to reduce HIV-related disparities. The strategy identifies a small number of action steps that will align efforts across federal, state, local, and tribal levels of government, and maximally impact the domestic HIV epidemic. In this article, we outline key programmatic and research issues that must be addressed to accomplish the prevention goals of the National HIV/AIDS Strategy.

Abstract
BACKGROUND National guidelines for the care of human immunodeficiency virus (HIV)-infected persons recommend asymptomatic routine screening for sexually transmitted diseases (STDs). Our objective was to determine whether providers who care for HIV-infected men who have sex with men (MSM) followed these guidelines. METHODS We abstracted medical records to evaluate STD screening at 8 large HIV clinics in 6 US cities. We estimated the number of men who had at least one test for syphilis, chlamydia (urethral and/or rectal), or gonorrhea (urethral, rectal, and/or pharyngeal) in 2004, 2005, and 2006. Urethral testing included nucleic acid amplification tests of both urethral swabs and urine. We also calculated the positivity of syphilis, chlamydia, and gonorrhea among screened men. RESULTS Medical records were abstracted for 1334 HIV-infected MSM who made 14,659 visits from 2004-2006. The annual screening rate for syphilis ranged from 66.0% to 75.8% during 2004-2006. Rectal chlamydia and rectal and pharyngeal gonorrhea annual screening rates ranged from 2.3% to 8.5% despite moderate to high positivity among specimens from asymptomatic patients (3.0%-9.8%) during this period. Annual urethral chlamydia and gonorrhea screening rates were higher than rates for nonurethral sites, but were suboptimal, and ranged from 13.8% to 18.3%. CONCLUSIONS Most asymptomatic HIV-infected MSM were screened for syphilis, indicating good provider adherence to this screening guideline. Low screening rates for gonorrhea and chlamydia, especially at rectal and pharyngeal sites, suggest that substantial barriers exist for complying with these guidelines. The moderate to high prevalence of asymptomatic chlamydial and gonococcal infections underscores the importance of screening. A range of clinical quality improvement interventions are needed to increase screening, including increasing the awareness of nucleic acid amplification tests for nonurethral screening.

Abstract
OBJECTIVES As a result of the impact of HIV among men who have sex with men (MSM), multiple strategies for reducing HIV risks have emerged from within the gay community. One common HIV risk reduction strategy limits unprotected sex partners to those who are of the same HIV status (serosorting). We tested a novel, brief, one-on-one intervention, based on informed decision-making and delivered by peer counselors, designed to address the limitations of serosorting (e.g., risk for HIV transmission). METHODS In 2009, we recruited a group of 149 at-risk men living in Atlanta, Georgia, and randomly assigned them to an intervention condition addressing serosorting or a standard-of-care control condition. RESULTS Men in the serosorting intervention reported fewer sexual partners (Wald χ(2) = 8.79, P < .01) at the study follow-ups. Behavioral results were also consistent with changes in psychosocial variables, including condom use self-efficacy and perceptions of risk for HIV transmission. CONCLUSIONS With the current intervention, service providers can offer risk reduction for men arguably at the highest risk for HIV infection in the United States. Addressing risks associated with serosorting in a feasible, low-cost intervention has the potential to significantly affect the HIV epidemic.

Abstract
We assessed trends in behavioral risk for HIV infection among men who have sex with men (MSM). Seattle MSM participated in random digit dial telephone surveys in 2003 (n = 400) and 2006 (n = 400). Fourteen percent in 2003 and 9% in 2006 reported unprotected anal intercourse with a partner of different or unknown HIV status (non-concordant UAI; odds ratio [OR] = 0.7; 95% confidence interval [CI]: 0.5, 1.2). Compared to participants in 2003, participants in 2006 met a greater proportion of their anal sex partners through the Internet (OR = 2.0; 95% CI: 1.2, 3.1). Although the proportion of anal sex partnerships formed online increased between 2003 and 2006, Internet partnerships were not more risky than those initiated elsewhere. While the emergence of the Internet as a venue through which men meet partners demonstrates that sexual risk among MSM remains highly dynamic, our findings suggest that sexual risk behavior among MSM is currently stable.

Abstract
We examined antiretroviral therapy (ART) use among 501 previously diagnosed HIV-infected men who have sex with men who sought care at a sexually transmitted disease clinic in King County, WA, during 2004-2008. Overall, 42% of men were not taking ART, 71% of whom had CD4 counts >350 cells per microliter. Of those who reported unprotected anal intercourse with a partner of nonconcordant HIV status in the prior year, 48% were not taking ART (78% with CD4 counts >350 cells/μL). Sexually transmitted disease clinics may be an important venue in which to identify persons who are not taking ART. Treating these persons could help diminish HIV transmission.

Abstract
Serosorting, the practice of selectively engaging in unprotected sex with partners of the same HIV serostatus, has been proposed as a strategy for reducing HIV transmission risk among men who have sex with men (MSM). However, there is a paucity of scientific evidence regarding whether women engage in serosorting. We analyzed longitudinal data on women's sexual behavior with male partners collected in the Women's Interagency HIV Study from 2001 to 2005. Serosorting was defined as an increasing trend of unprotected anal or vaginal sex (UAVI) within seroconcordant partnerships over time, more frequent UAVI within seroconcordant partnerships compared to non-concordant partnerships, or having UAVI only with seroconcordant partners. Repeated measures Poisson regression models were used to examine the associations between serostatus partnerships and UAVI among HIV-infected and HIV-uninfected women. The study sample consisted of 1,602 HIV-infected and 664 HIV-uninfected women. Over the follow-up period, the frequency of seroconcordant partnerships increased for HIV-uninfected women but the prevalence of UAVI within seroconcordant partnerships remained stable. UAVI was reported more frequently within HIV seroconcordant partnerships than among serodiscordant or unknown serostatus partnerships, regardless of the participant's HIV status or types of partners. Among women with both HIV-infected and HIV-uninfected partners, 41% (63 HIV-infected and 9 HIV-uninfected) were having UAVI only with seroconcordant partners. Our analyses suggest that serosorting is occurring among both HIV-infected and HIV-uninfected women in this cohort.

Abstract
Guided by a modified information-motivation-behavioral skills model, this study identified predictors of condom use among heterosexual people living with HIV with their steady partners. Consecutive patients at 14 European HIV outpatient clinics received an anonymous, standardized, self-administered questionnaire between March and December 2007. Data were analyzed using descriptive statistics and two-step backward elimination regression analyses stratified by gender. The survey included 651 participants (n = 364, 56% women; n = 287, 44%). Mean age was 39 years for women and 43 years for men. Most had acquired HIV sexually and more than half were in a serodiscordant relationship. Sixty-three percent (n = 229) of women and 59% of men (n = 169) reported at least one sexual encounter with a steady partner 6 months prior to the survey. Fifty-one percent (n = 116) of women and 59% of men (n = 99) used condoms consistently with that partner. In both genders, condom use was positively associated with subjective norm conducive to condom use, and self-efficacy to use condoms. Having a partner whose HIV status was positive or unknown reduced condom use. In men, higher education and knowledge about condom use additionally increased condom use, while the use of erectile-enhancing medication decreased it. For women, HIV disclosure to partners additionally reduced the likelihood of condom use. Positive attitudes to condom use and subjective norm increased self-efficacy in both genders, however, a number of gender-related differences appeared to influence self-efficacy. Service providers should pay attention to the identified predictors of condom use and adopt comprehensive and gender-related approaches for preventive interventions with people living with HIV.

Abstract
PURPOSE OF REVIEW Sexual intercourse represents the majority of HIV transmission and is preventable. Overall, the risk of HIV transmission following a single sexual exposure is low especially in comparison with other sexually transmitted infections (STIs), with estimates of the average probability of male-to-female HIV transmission only 0.0005-0.0026 per coital act. The risk of acquiring HIV from a single contact varies enormously and is dependant upon the infectiousness of the HIV-positive individual and the susceptibility to HIV of their sexual partner. RECENT FINDINGS Of concern, unprotected sex among men who have sex with men (MSM) has increased in recent years and HIV incidence in both MSM and heterosexuals remains a considerable public health concern. Sexual practices and health optimism about HIV have changed, which have significantly impacted HIV risk behaviour. SUMMARY In this review article we summarize the current evidence regarding the observed relative risks of HIV transmission for each different types of sex act, relationship type and the strategies that have been tested to interrupt transmission.

Abstract
This paper compares the sexual and reproductive experiences and intentions of those adolescents aged 15-19 years in Uganda who are perinatally infected with HIV and know their sero-status with those of adolescents who do not know their sero-status. The analysis comprises a simple comparison of means and proportions, together with the relevant tests of significance, as well as estimation of Cox proportional hazards and random-effects logit models. The findings show that the two groups of adolescents do not differ significantly in terms of timing of sexual debut and whether they intend to have children in the future. However, adolescents who are HIV-positive and know their status are significantly more likely to use a modern method of contraception, including condoms. Nonetheless, the level of condom use among these adolescents is still limited (less than half of those sexually active) and inconsistent (less than half of those in relationships reported always using a condom).

Abstract
This mixed methods study evaluated the efficacy of an intervention to increase HIV status disclosure and condom use among 184 women living with HIV/AIDS (WLH/A). Participants were recruited from an HIV clinic and randomly assigned to: (1) a comparison group, who received brief messages from their health care providers (HCPs), or; (2) an intervention group, who received messages from HCPs, a group-level intervention, and peer-led support groups. Participants completed risk surveys at baseline, 6-, 12-, and 18-months. Quantitative analyses using hierarchical generalized linear models within a repeated measures framework indicated that intervention participants had significantly higher odds of reporting condom use with sexual partners in months 6 and 18. Grounded Theory-based qualitative analyses suggested that the opportunity to discuss the social context of their lives in addition to HIV/AIDS, including continued stigma and fear related to disclosure, are also essential components of a prevention strategy for WLH/A.

Abstract
Sexually transmitted diseases (STDs) occur often among sexually active persons with HIV infection. Incident STDs may complicate the course of HIV infection and potentiate HIV transmission in the coinfected individual by mucosal disruption and an increase in HIV concentration in ulcers and involved mucous membranes. Conducting ongoing periodic sexual risk assessments in HIV-positive patients in routine medical care is critical to identifying asymptomatic infections. HIV clinicians should be familiar with updated recommendations for screening, diagnosis, and treatment of bacterial and viral STDs, including those specific to HIV infection. This article addresses emerging issues in the management of STDs in HIV-infected persons and summarizes the latest evidence that can be applied to clinical decision-making in this population.

Abstract
BACKGROUND Commercial sex venues such as bathhouses and sex clubs have long been considered important facilitators of HIV transmission among men who have sex with men in the United States. Recent probability surveys of commercial-sex-venue patrons in King County, WA that included data on behavior both within and outside these venues provide an empirical basis for the development of mathematical models to estimate the role that commercial sex venues play in the HIV epidemic. METHODS We constructed deterministic compartmental mathematical models of HIV transmission to estimate both current incidence among King County men who have sex with men and incidence in 5 counterfactual scenarios in which commercial-sex-venues were presumed not to exist. We parameterized the models using a range of values for the proportion of commercial sex venues partnerships replaced in the absence of these venues, and the number of acts of unprotected anal intercourse per other types of partnership. Yearly attributable number was calculated as the difference between incident HIV cases in the main models and each corresponding counterfactual model. We performed extensive sensitivity analyses using Latin hypercube sampling. RESULTS Replacement of 25% of commercial sex venue partners in the absence of these venues resulted in attributable number values near zero per year. Replacement of 50% or more of commercial sex venue partners resulted in negative yearly attributable numbers, indicating a net increase in incident HIV infections in the absence of these venues. Results of the sensitivity analyses were consistent with the main findings. CONCLUSIONS Our findings imply that commercial sex venues contribute little to the burden of HIV among men who have sex with men in King County, WA.

Abstract
A common HIV/AIDS risk reduction strategy among men who have sex with men (MSM) is to limit their unprotected sex partners to those who are of the same HIV status, a practice referred to as serosorting. Decisions to serosort for HIV risk reduction are based on personal impressions and beliefs, and there is limited guidance offered on this community derived strategy from public health services. This paper reviews research on serosorting for HIV risk reduction and offers an evidence-based approach to serosorting guidance. Following a comprehensive electronic and manual literature search, we reviewed 51 studies relating to the implications of serosorting. Studies showed that HIV negative MSM who select partners based on HIV status are inadvertently placing themselves at risk for HIV. Infrequent HIV testing, lack of HIV status disclosure, co-occurring sexually transmitted infections, and acute HIV infection impede the potential protective benefits of serosorting. Public health messages should continue to encourage reductions in numbers of sexual partners and increases in condom use. Risk reduction messages should also highlight the limitations of relying on one's own and partner's HIV status in making sexual risk decisions.

Abstract
The sexual and reproductive health needs of young people perinatally infected with HIV in Uganda remain largely unaddressed by existing HIV/AIDS programs mostly because, such programs encourage young HIV-positive clients to refrain from or postpone sexual activity. This study examines the sexual expressions and experiences as well as the preventive practices of 732 adolescent boys and girls aged 15-19 years who were born with HIV with a view to identifying the preventive service needs of these young people and the implications of these needs for HIV/AIDS programs. The data come from a project on the sexuality of young people perinatally infected with HIV conducted in 2007 in four districts of Uganda, that is, Kampala, Wakiso, Masaka, and Jinja. The analysis involves both quantitative and qualitative approaches: the quantitative approach entails cross-tabulations with chi-square tests as well as significance tests of proportions while the qualitative approach involves an analysis of individual case stories, in-depth probes and focus group discussions for content. The findings show disconnect between: (1) the information the service providers give to the young people and their actual needs and desires; (2) the fears of the adolescents and their actual preventive practices; and (3) the high level of reported condom use and the frequency of use. Programs will therefore need to recognize that young people perinatally infected with HIV are sexually active or anticipate being so in future. Thus, both sexually active and non-sexually active young people require information and services on prevention of unwanted pregnancies as well as avoiding infecting their sexual partners with HIV and re-infecting themselves. Programs will need to devise ways of responding to these needs which should include emphasizing the disclosure of HIV status to the partner as well as the need to accompany such disclosure with consistent condom use.

Abstract
OBJECTIVE We sought to estimate how serosorting may affect HIV prevalence and individual risk among men who have sex with men in Seattle, Washington, and how the results vary under different assumptions of HIV testing frequency, heterogeneity in sexual behavior, and condom use. METHODS We developed a deterministic mathematical model of HIV transmission dynamics. Data from the 2003 random digit dial study of men who have sex with men conducted in Seattle, Washington (n = 400) are used to parameterize the model. RESULTS Predicted population-level HIV prevalence as well as an individual's risk of HIV acquisition decreases when the odds of serosorting are increased in the mathematical model. In our model based on observed levels of serosorting, we predict an HIV prevalence of 16%. In contrast, if serosorting were eliminated in the population, we predict that HIV prevalence would increase to 24.5%. However, our findings depend on rates of condom use, mean anal sex contact rates, and HIV testing in the population. CONCLUSION Under realistic scenarios of sexual behavior and testing frequency for men who have sex with men in the United States, serosorting can be an effective harm reduction strategy.

Abstract
OBJECTIVES To describe trends in the occurrence and frequency of HIV testing among men who have sex with men (MSM) receiving care in 4 US sexually transmitted disease (STD) clinics and to define factors associated with HIV testing frequency and positivity. STUDY DESIGN Routine clinical encounters during 57,131 visits by MSM to STD clinics in 4 cities (Seattle-King County, San Francisco, Denver, and District of columbia), 2002-2006, were examined. RESULTS From 2002 to 2006, a city-specific median of 69.1% of presumptive HIV-uninfected MSM were tested for HIV, of which, a median of 86.7% had previously tested (4.5% unknown) and a median of 3.9% were newly diagnosed with HIV. Between 2002 and 2006, the median percentage of tested MSM who reported no previous HIV testing decreased from 9.4% to 5.4% (P = 0.01) and the city-specific median intertest interval decreased from 302 to 243 days (P = 0.03). Among MSM with newly diagnosed HIV, the median intertest interval decreased from 531 days in 2002 to 287 days in 2006 (P = 0.001). Predictors of newly diagnosed HIV infection included the following: younger age, longer intertest interval, black or Hispanic race/ethnicity, clinic in San Francisco, and concurrent diagnosis with a bacterial STD. CONCLUSIONS In MSM seen at 4 STD clinics, the percentage of never previously HIV tested is decreasing and MSM are testing more frequently.

Abstract
Health departments inconsistently provide partner notification services to persons with HIV. We surveyed a randomly selected sample of 370 patients at the largest HIV clinic in Washington State, USA, using a self-administered anonymous questionnaire. Patients who reported talking to health department staff about partner notification were more likely to report notifying at least one sex partner following their HIV diagnosis than patients who did not talk to health department staff (68 vs. 45%, odds ratio = 2.5, 95% confidence interval = 1.6-3.9).

Abstract
BACKGROUND Little data exist on Internet and email use among STD clinic patients for research and clinical care communication. METHODS An anonymous cross-sectional survey of STD clinic patients aged >/=18 years in Seattle, WA, March 13 to 22, 2006. RESULTS Of 489 study period patients, 251 (51%) completed the questionnaire. Participants had a median age of 30 (range 18-66) years and were 69% male, 56% white, 19% black, 9% Hispanic, and 7% Asian/Pacific Islander. Of all participants, 75% had some postsecondary education but half reported an annual income of <US$15,000. Of 251 participants, 200 (80%) reported using the Internet from a private location at least once a week, 190 (76%) had their own email that they check at least 3 times a week, and 144 (57%) were willing to receive an email reminding them to come back for a follow-up appointment if diagnosed with an STD. Men who have sex with men were more likely than women and heterosexual men to be regular Internet and email users (92% vs. 70%, P = 0.001) and to have met a sex partner over the Internet during the past year (69% vs. 11%, P <0.001). Higher educational level and income, but not age or gender, were also associated with Internet and email use, as was racial/ethnic background (86% of whites, 48% of blacks, 73% of Hispanics, 100% of Asians/Pacific Islanders, and 57% of others, P <0.001). CONCLUSIONS Internet and email use are common and acceptable to many STD clinic patients for research and clinical purposes.

Abstract
Information about risky sexual behavior among people living with HIV/AIDS is important to prevent the spread of the disease. Using an anonymous, self-administrated questionnaire, we surveyed 185 HIV-infected patients about risk behaviors at the University Hospital for Infectious Diseases in Croatia. Unprotected anal or vaginal sex in the preceding 6 months with partners of uninfected/unknown HIV status was reported by 20% of men who have sex with men (MSM), about half of whom reported multiple casual partners of unknown HIV status; 6% of heterosexual men; and 3% of women. Heterosexual patients were potentially more likely to expose regular partners to HIV but reported no risk behaviors with casual, non-concordant partners. MSM reported more risk behaviors, which were strongly associated with having > or = 2 sexual partners in the last 6 months and both insertive and receptive anal sex. Educational interventions in Croatia should target MSM to prevent high rates of HIV transmission.
