Exploring the seasonality and optimal control strategy of HIV/AIDS epidemic in China: The impact of seasonal testing

In this work, we investigate how the seasonal variation in the number of individuals who are tested for an HIV antibody in outpatient clinics affects the HIV transmission patterns in China, which has not been well studied. Based on the characteristics of outpatient testing data and reported cases, we establish a periodic infectious disease model to study the impact of seasonal testing on HIV transmission. The results indicate that the seasonal testing is a driving factor for the seasonality of new cases. We demonstrate the feasibility of ending the HIV/AIDS epidemic. We find that the diagnostic rates related to testing play a crucial role in controlling the size of the epidemic. Specifically, when considering minimizing both infected individuals and diagnostic rates, the level of attention paid to undiagnosed infected individuals is always positively correlated with the optimal diagnostic rates, while the optimal diagnostic rates are negatively correlated with the size of the epidemic at the terminal time.

Behaviour changes following HIV diagnosis among men who have sex with men in the era of treatment as prevention: data from a prospective study

We described the longitudinal changes in sexual behaviour and associated factors among newly diagnosed with HIV men who have sex with men participating in a prospective observational study from a London HIV clinic (2015-2018). Participants self-completed questionnaires at baseline, months 3 and 12. Information collected included socio-demographic, sexual behaviour, health, lifestyle and social support. Trends in sexual behaviours over one year following diagnosis and associated factors were assessed using generalized estimating equations with logit link. Condomless sex (CLS) dropped from 62.2% at baseline to 47.6% at month-three but increased again to 61.8% at month-12 (p-trend = 0.790). Serodiscordant-CLS increased between month-three and month-12 (from 13.1% to 35.6%, p-trend < 0.001). The prevalence of serodiscordant-CLS with high risk of transmitting to their partners at month-three was 10.7%. CLS was higher among men who reported recreational drug use (adjusted Odds Ratio (aOR) 3.03, 95%CI 1.47-6.24, p = 0.003), those with undetectable viral load (aOR 2.17, 95%CI 1.22-3.84, p = 0.008) and those who agreed with a statement "condoms are not necessary when HIV viral load is undetectable" (aOR 3.41, 95%CI 1.58-7.38, p = 0.002). MSM continued to engage in CLS after HIV diagnosis, which coincided with U = U publications and increased throughout the study.

Determinants of HIV Testing Among Migrant Men Who Have Sex With Men from Sub-Saharan Africa and Other Regions Residing in 10 European Countries

Migrant men who have sex with men (mMSM) from sub-Saharan Africa (SSA) and other regions outside Europe are highly vulnerable to HIV. However, research on the determinants of HIV testing among mMSM from SSA, and how these differ across the categories of mMSM living in Europe, is limited. Using data from the European MSM Internet Survey (EMIS-2017), we assessed HIV testing prevalence and recency in mMSM from SSA and other mMSM residing in ten European countries, as well as the determinants of HIV testing across different mMSM categories with logistic regression analyses. Ever-testing for HIV was slightly higher in mMSM from SSA (83%) compared to other mMSM categories (75-80%), except for mMSM from Latin America and Caribbean region (84%). Overall, 20% of mMSM had never tested. In multivariable analysis, higher age (adjusted odds ratio [AOR] 1.05, 95% confidence interval [CI] 1.01-1.10), higher HIV knowledge (AOR 1.45, 95%-CI 1.11-1.90), and residence in smaller settlements (AOR 0.45, 95%-CI 0.21-0.96) were significantly associated with ever testing for HIV in mMSM from SSA. Comparing mMSM from SSA to mMSM from other regions, we found varying significant similarities (higher age, residence in smaller settlements and HIV knowledge) and differences (lower educational attainment, not identifying as gay, being a student, and limited disclosure of homosexual attraction) in the determinants of ever-testing for HIV. Community-specific interventions addressing identified sociodemographic and behavioral determinants to increase HIV testing uptake in the different mMSM categories and better data for further research are warranted.

Impact of COVID-19 pandemic on Tuberculosis and HIV services in Ghana: An interrupted time series analysis

INTRODUCTION

The Coronavirus disease 2019 (COVID-19) burden, coupled with unprecedented control measures including physical distancing, travel bans, and lockdowns of cities, implemented to stop the spread of the virus, have undoubtedly far-reaching aftereffects on other diseases. In low and middle-income countries (LMICs), a particular worry is the potential impact on Human Immunodeficiency Virus (HIV) and Tuberculosis (TB), as a consequence of possible disruption to health services and limiting access to needed life-saving health care. In Ghana, there is a paucity of information regarding the impact of COVID-19 on disease control, particularly TB and HIV control. This study sought to contribute to bridging this knowledge gap.

METHOD

The study involved the analysis of secondary data obtained from the District Health Information Management System-2 (DHIMS-2) database of Ghana Health Service, from 2016 to 2020. Data were analysed using an interrupted time-series regression approach to estimate the impact of COVID-19 on TB case notification, HIV testing, and Antiretroviral Therapy (ART) initiations, using March 2020 as the event period.

RESULTS

The study showed that during the COVID-19 pandemic period, there was an abrupt decline of 20.5% (955CI: 16.0%, 24.5%) in TB case notifications in April and 32.7% (95%CI: 28.8%, 39.1%) in May 2020, with a median monthly decline of 21.4% from April-December 2020. A cumulative loss of 2,128 (20%; 95%CI: 13.3%, 26.7%) TB cases was observed nationwide as of December 2020. There was also a 40.3% decrease in people presenting for HIV tests in the first month of COVID-19 (April 2020) and a cumulative loss of 262620 (26.5%) HIV tests as of December 2020 attributable to the COVID-19 pandemic. ART initiations increased by 39.2% in the first month and thereafter decreased by an average of 10% per month from May to September 2020. Cumulatively, 443 (1.9%) more of the people living with HIV initiated ART during the pandemic period, however, this was not statistically significant.

CONCLUSION

This study demonstrated that the COVID-19 pandemic negatively impacted TB case notifications and HIV testing and counselling services, However, ART initiation was generally not impacted during the first year of the pandemic. Proactive approaches aimed at actively finding the thousands of individuals with TB who were missed in 2020 and increasing HIV testing and counselling and subsequent treatment initiations should be prioritised.

Changes in COVID-19 Vaccine Acceptability among Parents with Children Aged 6-35 Months in China-Repeated Cross-Sectional Surveys in 2020 and 2021

China is considering to offer COVID-19 vaccination for children aged 6−35 months. This study investigated the changes in COVID-19 vaccine acceptability and associated factors among parents with children aged 6−35 months in 2020 and 2021. Two rounds of cross-sectional online surveys were conducted among adult factory workers in Shenzhen, China. A subset of 208 (first round) and 229 (second round) parents with at least one child aged 6−35 months was included in the study. Parental acceptability of COVID-19 vaccination increased significantly from 66.8% in the first round to 79.5% in the second round (p = 0.01). Positive attitudes, perceived subjective norm, and perceived behavioral control were associated with higher parental acceptability in both rounds of surveys (p values ranged from <0.001 to 0.003). A negative association of negative attitudes with parental acceptability was observed in the second round (p = 0.02). No significant associations of exposure to information related to COVID-19 vaccination on social media with parental acceptability was found in either round of survey. Expanding the existing COVID-19 vaccination programs to cover children aged 6−35 months is necessary in China. Future programs should focus on modifying perceptions among parents to promote COVID-19 vaccination for children in this age group.

Behavioural intervention to reduce sexually transmitted infections in people aged 16–24 years in the UK: the safetxt RCT

Background

The prevalence of genital chlamydia and gonorrhoea is higher in the 16–24 years age group than those in other age group. With users, we developed the theory-based safetxt intervention to reduce sexually transmitted infections.

Objectives

To establish the effect of the safetxt intervention on the incidence of chlamydia/gonorrhoea infection at 1  year.

Design

A parallel-group, individual-level, randomised superiority trial in which care providers and outcome assessors were blinded to allocation.

Setting

Recruitment was from 92 UK sexual health clinics.

Participants

Inclusion criteria were a positive chlamydia or gonorrhoea test result, diagnosis of non-specific urethritis or treatment started for chlamydia/gonorrhoea/non-specific urethritis in the last 2 weeks; owning a personal mobile phone; and being aged 16–24 years.

Allocation

Remote computer-based randomisation with an automated link to the messaging system delivering intervention or control group messages.

Intervention

The safetxt intervention was designed to reduce sexually transmitted infection by increasing partner notification, condom use and sexually transmitted infection testing before sex with new partners. It employed educational, enabling and incentivising content delivered by 42–79 text messages over 1 year, tailored according to type of infection, gender and sexuality.

Comparator

A monthly message regarding trial participation.

Main outcomes

The primary outcome was the incidence of chlamydia and gonorrhoea infection at 12 months, assessed using nucleic acid amplification tests. Secondary outcomes at 1 and 12 months included self-reported partner notification, condom use and sexually transmitted infection testing prior to sex with new partner(s).

Results

Between 1 April 2016 and 23 November 2018, we assessed 20,476 people for eligibility and consented and randomised 6248 participants, allocating 3123 to the safetxt intervention and 3125 to the control. Primary outcome data were available for 4675 (74.8%) participants. The incidence of chlamydia/gonorrhoea infection was 22.2% (693/3123) in the intervention group and 20.3% (633/3125) in the control group (odds ratio 1.13, 95% confidence interval 0.98 to 1.31). There was no evidence of heterogeneity in any of the prespecified subgroups. Partner notification was 85.6% in the intervention group and 84.0% in the control group (odds ratio 1.14, 95% confidence interval 0.99 to 1.33). At 12 months, condom use at last sex was 33.8% in the intervention group and 31.2% in the control group (odds ratio 1.14, 95% confidence interval 1.01 to 1.28) and condom use at first sex with most recent new partner was 54.4% in the intervention group and 48.7% in the control group (odds ratio 1.27, 95% confidence interval 1.11 to 1.45). Testing before sex with a new partner was 39.5% in the intervention group and 40.9% in the control group (odds ratio 0.95, 95% confidence interval 0.82 to 1.10). Having two or more partners since joining the trial was 56.9% in the intervention group and 54.8% in the control group (odds ratio 1.11, 95% confidence interval 1.00 to 1.24) and having sex with someone new since joining the trial was 69.7% in the intervention group and 67.4% in the control group (odds ratio 1.13, 95% confidence interval 1.00 to 1.28). There were no differences in safety outcomes. Additional sensitivity and per-protocol analyses showed similar results.

Limitations

Our understanding of the mechanism of action for the unanticipated effects is limited.

Conclusions

The safetxt intervention did not reduce chlamydia and gonorrhoea infections, with slightly more infections in the intervention group. The intervention increased condom use but also increased the number of partners and new partners. Randomised controlled trials are essential for evaluating health communication interventions, which can have unanticipated effects.

Future work

Randomised controlled trials evaluating novel interventions in this complex area are needed.

Trial registration

This trial is registered as ISRCTN64390461.

Re-assessing the late HIV diagnosis surveillance definition in the era of increased and frequent testing

OBJECTIVES

Late HIV diagnosis (CD4 <350 cells/mm³ ) is a key public health metric. In an era of more frequent testing, the likelihood of HIV diagnosis occurring during seroconversion, when CD4 counts may dip below 350, is greater. We applied a correction, considering markers of recent infection, and re-assessed 1-year mortality following late diagnosis.

METHODS

We used national epidemiological and laboratory surveillance data from all people diagnosed with HIV in England, Wales, and Northern Ireland (EW&NI). Those with a baseline CD4 <350 were reclassified as 'not late' if they had evidence of recent infection (recency test and/or negative test within 24 months). A correction factor (CF) was the number reclassified divided by the number with a CD4 <350.

RESULTS

Of the 32 227 people diagnosed with HIV in EW&NI between 2011 and 2019 with a baseline CD4 (81% of total), 46% had a CD4 <350 (uncorrected late diagnosis rate): 34% of gay and bisexual men (GBM), 65% of heterosexual men, and 56% of heterosexual women. Accounting for recency test and/or prior negative tests gave a 'corrected' late diagnosis rate of 39% and corresponding CF of 14%. The CF increased from 10% to 18% during 2011-2015, then plateaued, and was larger among GBM (25%) than heterosexual men and women (6% and 7%, respectively). One-year mortality among people diagnosed late was 329 per 10 000 after reclassification (an increase from 288/10 000).

CONCLUSIONS

The case-surveillance definition of late diagnosis increasingly overestimates late presentation, the extent of which differs by key populations. Adjustment of late diagnosis is recommended, particularly for frequent testers such as GBM.

Recent HIV Infection: Diagnosis and Public Health Implications

The early period of infection with human immunodeficiency virus (HIV) has been associated with higher infectiousness and, consequently, with more transmission events. Over the last 30 years, assays have been developed that can detect viral and immune biomarkers during the first months of HIV infection. Some of them depend on the functional properties of antibodies including their changing titers or the increasing strength of binding with antigens over time. There have been efforts to estimate HIV incidence using antibody-based assays that detect recent HIV infection along with other laboratory and clinical information. Moreover, some interventions are based on the identification of people who were recently infected by HIV. This review summarizes the evolution of efforts to develop assays for the detection of recent HIV infection and to use these assays for the cross-sectional estimation of HIV incidence or for prevention purposes.

Evidence and implication of interventions across various socioecological levels to address HIV testing uptake among men who have sex with men in the United States: A systematic review

Objectives

Strengthening HIV testing uptake is critical to curtail the HIV epidemics among men who have sex with men in the United States. Despite the implementation of various interventions to promote HIV testing among men who have sex with men, few aggregated evidence is presented to reflect the "lessons learned" and inform future directions. The objective of this systematic review is to comprehensively summarize published studies that described, tested, and evaluated outcomes (e.g. efficacy, effectiveness, acceptability, feasibility and/or qualitative opinions) associated with an HIV testing intervention and identify gaps as well as opportunities to inform the design and implementation of future interventions to enhance HIV testing uptake among men who have sex with men in the United States.

Methods

We followed the PRISMA guidelines and conducted a systematic review of articles (published by 23 July 2021) by searching multiple databases (PubMed, MEDLINE, Web of Science and PsycINFO).

Results

Among the total number of 3505 articles found through multiple databases, 56 papers were included into the review. Interventional modules that demonstrated acceptability, feasibility and efficacy to improve HIV testing uptake among men who have sex with men include: HIV self-testing, interpersonal-level (e.g. peer-led, couple-based) interventions, personalized interventions and technology-based interventions (e.g. mHealth). Aggregated evidence also reflects the lack of individualized interventions that simultaneously address time-varying needs across multiple socioecological levels (e.g. individual, interpersonal, community, structural and societal).

Conclusion

Development of interventions to improve HIV testing rates and frequency of men who have sex with men has proliferated in recent years. Our review presents important implications in sustaining and improving interventions to address HIV testing uptake among men who have sex with men in the United States.

Exploring Contextual Differences for Sexual Role Strain Among Transgender Women and Men Who Have Sex with Men in Lima, Peru

Sexual and gender politics inform relational expectations surrounding sexual experiences of Peruvian transgender women (TW) and men who have sex with men (MSM). We used the framework of sexual role strain, or incongruence between preferred sexual role and actual sexual practices, to explore potential conflicts between personally articulated identities and externally defined norms of gender and sexuality and its potential to increase HIV/STI risk. Cross-sectional individual- and dyad-level data from 766 TW and MSM in Lima, Peru were used to assess the partnership contexts within which insertive anal intercourse was practiced despite receptive role preference (receptive role strain), and receptive anal intercourse practiced despite insertive role preference (insertive role strain). Sexual role strain for TW was more common with non-primary partners, while for MSM it occurred more frequently in the context of a primary partnership. Receptive role strain was more prevalent for TW with unknown HIV status (reference: without HIV) or pre-sex drug use (reference: no pre-sex drug use). For homosexual MSM, receptive role strain was more prevalent during condomless anal intercourse (reference: condom-protected) and with receptive or versatile partners (reference: insertive). Among heterosexual or bisexual MSM, insertive role strain was more prevalent with insertive or versatile partners (reference: receptive), and less prevalent with casual partners (reference: primary). Our findings suggest TW and MSM experience different vulnerabilities during sexual role negotiation with different partner-types. Future studies should explore the impact of sexual role strain on condom use agency, HIV/STI risk, and discordances between public and private presentations of gender and sexual orientation.

Structural Stigma and Sexual Health Disparities Among Gay, Bisexual, and Other Men Who Have Sex With Men in Australia

BACKGROUND

Discrimination and stigmatization at the institutional and sociocultural level (conceptualized as "structural stigma") has been associated with adverse health outcomes among sexual and gender minorities. However, few studies explore whether structural stigma is associated with sexual health outcomes. Addressing this gap, here, we explore this relationship among Australian gay, bisexual, and other men who have sex with men (GBM)-a population disproportionately affected by HIV.

SETTING AND METHODS

Using responses from the 2017 Australian Marriage Law Postal Survey, we operationalized structural stigma related to sexual minority status as the regional percentage of votes against legalizing same-sex marriage. These responses were then linked to national HIV behavioral surveillance data from Australian GBM (43,811 responses between 2015 and 2019). Controlling for a rich set of individual and regional level confounders, regression analyses were used to estimate the extent to which structural stigma was associated with testing for, and diagnoses of, HIV and sexually transmitted infections (STIs), and awareness and use of HIV prevention and treatment interventions (pre-exposure and postexposure prophylaxis, combination therapy, and HIV-related clinical care).

RESULTS

Australian GBM living in regions with higher levels of structural stigma were less likely to undergo HIV/STI testing, receive HIV/STI diagnoses, and be taking, or aware of, biomedical prevention strategies. Among GBM living with HIV, structural stigma was associated with a reduced likelihood of being on combination therapy and fewer HIV-related clinical visits.

CONCLUSIONS

Altogether, these results suggest that structural stigma may undermine HIV prevention strategies as well as adequate management of HIV infection among GBM.

Ethical considerations for HIV remission clinical research involving participants diagnosed during acute HIV infection

HIV remission clinical researchers are increasingly seeking study participants who are diagnosed and treated during acute HIV infection—the brief period between infection and the point when the body creates detectable HIV antibodies. This earliest stage of infection is often marked by flu-like illness and may be an especially tumultuous period of confusion, guilt, anger, and uncertainty. Such experiences may present added ethical challenges for HIV research recruitment, participation, and retention. The purpose of this paper is to identify potential ethical challenges associated with involving acutely diagnosed people living with HIV in remission research and considerations for how to mitigate them. We identify three domains of potential ethical concern for clinicians, researchers, and ethics committee members to consider: 1) Recruitment and informed consent; (2) Transmission risks and partner protection; and (3) Ancillary and continuing care. We discuss each of these domains with the aim of inspiring further work to advance the ethical conduct of HIV remission research. For example, experiences of confusion and uncertainty regarding illness and diagnosis during acute HIV infection may complicate informed consent procedures in studies that seek to recruit directly after diagnosis. To address this, it may be appropriate to use staged re-consent procedures or comprehension assessment. Responsible conduct of research requires a broad understanding of acute HIV infection that encompasses its biomedical, psychological, social, and behavioral dimensions. We argue that the lived experience of acute HIV infection may introduce ethical concerns that researchers and reviewers should address during study design and ethical approval.

Association of experienced and internalized stigma with self-disclosure of HIV status by youth living with HIV

We examined patterns of disclosure among youth living with HIV (YLHIV) in Kenya, and the association between self-disclosure and antiretroviral therapy adherence, stigma, depression, resilience, and social support. Of 96 YLHIV, 78% were female, 33% were ages 14-18, and 40% acquired HIV perinatally. Sixty-three (66%) YLHIV had self-disclosed their HIV status; 67% to family and 43% to non-family members. Older YLHIV were 75% more likely to have self-disclosed than those 14-18 years. Of the 68 either married or ever sexually active, 45 (66%) did not disclose to their partners. Those who had self-disclosed were more likely to report internalized stigma (50% vs. 21%, prevalence ratio [PR] 2.3, 1.1-4.6), experienced stigma (26% vs. 3%, PR 11.0, 1.4-86), and elevated depressive symptoms (57% vs. 30%, PR 1.8, 1.0-3.1). The association with stigma was stronger with self-disclosure to family than non-family. Support should be provided to YLHIV during self-disclosure to mitigate psychosocial harms.

HIV Infection: Time from Diagnosis to Initiation of Antiretroviral Therapy in Portugal, a Multicentric Study

The benefits of antiretroviral therapy (ART) for persons living with HIV (PLWH) are well established. Rapid ART initiation can lead to improved clinical outcomes. Portugal has one of the highest rates of new HIV diagnoses in the European Union, and an average time until ART initiation above the recommendations established by the national guideline according to data from the first two years after its implementation in 2015, with no more recent data available after that. This study aimed to evaluate time from the first hospital appointment until ART initiation among newly diagnosed HIV patients in Portugal between 2017 and 2018, to investigate differences between hospitals, and to understand the experience of patient associations in supporting the navigation of PLWH throughout referral and linkage to the therapeutic process. To answer to these objectives, a twofold design was followed: a quantitative approach, with an analysis of records from five Portuguese hospitals, and a qualitative approach, with individual interviews with three representatives of patient associations. Overall, 847 and 840 PLWH initiated ART in 2017 and in 2018, respectively, 21 days (median of the two years) after the first appointment, with nearly half coming outside the mainstream service for hospital referral, and with observed differences between hospitals. In 2017-2018, only 38.0% of PLWH initiated ART in less than 14 days after the first hospital appointment. From the interviews, barriers of administrative and psychosocial nature were identified that may hinder access to ART. Patient associations work to offer a tailored support to patients' navigation within the health system, which can help to reduce or overcome those potential barriers. Indicators related to time until ART initiation can be used to monitor and improve access to specialized care of PLWH.

Childhood Sexual Trauma and Antiretroviral Therapy Adherence: A Mixed-Methods Systematic Review

Childhood sexual abuse (CSA) has been shown to be more prevalent among populations living with HIV. Antiretroviral therapy (ART) adherence is crucial for populations living with HIV as it significantly increases the likelihood of attaining and maintaining viral suppression. Previous findings on the association between CSA and ART adherence have been mixed. The current mixed-methods systematic review aimed to identify quantitative and qualitative studies from CINAHL, PsycInfo, PubMed, and Web of Science examining the relationship between CSA and ART adherence. Authors were also contacted if relevant data were unpublished. Studies had to be published from January 1, 2000 to April 1, 2019, written in English, and examined CSA as an exposure and ART adherence as an outcome. Four domains were combined: 1) childhood sexual abuse; 2) child; 3) antiretroviral; and 4) adherence. Eight quantitative and two qualitative studies were retained. The results showed that four quantitative studies found no association while the other four found factors such as timing of victimization, mental health and gender influenced the association between CSA and ART adherence. Themes emerging from the qualitative studies included use of ART evoking memories of CSA; CSA impacting mental health; and mental health treatment improving ART adherence. Mixed insights included the intricate links between CSA and ART adherence and the role of external factors on the relationship. ART adherence intervention programs may be needed for people who have experienced CSA. However, future studies are needed that will examine the association between CSA and ART adherence and include subgroup analyses.

The Politics of LGBT+ Health Inequality: Conclusions from a UK Scoping Review

This scoping review of UK evidence aimed to describe what is known about Lesbian, Gay, Bisexual, and Trans (LGBT+) health inequalities in relation to cancer, mental health, and palliative care to inform research, policy and public health interventions. Using a scoping review methodology, we identified studies from database searches, citation tracking, and expert consultation. The in/exclusion criteria was based on the PICOS framework. The data were charted and then summarised to map the theoretical approaches and the main types of evidence and identify knowledge gaps. In total, 279 articles were screened and 83 were included in the final review. We found that there is limited UK research examining LGBT+ health inequality in cancer, mental health and palliative care. We would argue that this thin evidence base is partly due to national policy discussions of LGBT+ health inequality that are framed within a depoliticised ‘it’s getting better’ narrative, and an unwillingness to adequately acknowledge the unjust social and economic relations that produce LGBT+ health inequality. In addition, LGBT+ health inequality is depoliticised by existing public health explanatory theories, models and frameworks that exclude sexual orientation and gender diversity as dimensions of power that interlock with those of socio-economic, race and ethnicity. This is a barrier to developing public health interventions that can successfully tackle LGBT+ health inequality

Barriers and Facilitators for HIV Testing Practice Among Ethiopian Women Aged 15-24 years: Analysis of the 2016 Ethiopian Demographic and Health Survey

BACKGROUND

In developing countries, youth women are most at risk of HIV infection. Center for Disease Control recommends that people who participate in high-risk behaviors get tested for HIV at least annually. In 2016, the Ethiopian Ministry of Health set goals to identify 90% of the people living with HIV by 2030. But undiagnosed HIV infections are still high in the country. To alleviate the problem, it is vital to identify the factors that hinder HIV testing practice. Therefore, this study aimed to identify the facilitators and barriers of HIV testing practice among Ethiopian youth women.

METHODS

The analysis was done on 6401 women aged 15-24 years using data from the 2016 Ethiopia Demographic Health Survey (EDHS). The main outcome variable was self-reported HIV testing practice. Multivariable logistic regression was used to identify the facilitators and barriers of HIV testing practice.

RESULTS

In this study, 37.7% [95% CI: (33.6, 39.1)] of youth women were tested for HIV in their life. Being married (AOR=4.7; 95% CI: (3.67, 6.01)), divorced [AOR=6.2; 95% CI: (3.98-9.54)], having primary level of education [AOR=2.4;95% CI: (1.79-3.13)], and secondary level of education [AOR=4.0; 95% CI: (2.87-5.63)], being rich [AOR=2.3;95% CI: (1.39-3.91)] and being in the highest wealth index catagory [AOR=2.6;95% CI: (1.30-5.16)] increase the odds of HIV testing. However, lack of media acccess [AOR = 0.7; 95 CI %: (0.54-0.87)], lack of comprehensive HIV knowledge [AOR = 0.68; 65% CI: (0.53-0.86)] and having discriminatory attitude towards PLHIV[AOR=0.79;95% CI: (0.64-0.97)] decrease the odds of HIV testing.

CONCLUSION

The practice of HIV testing among youth populations was low as compared to national recommendations. Lack of media access, lack of comprehensive knowledge about HIV, and having discriminatory attitudes were the barriers to HIV testing practice. Marriage, secondary or higher education attainment, and high wealth index category were the facilitators for HIV testing. Improving HIV-related knowledge, improving media access, and minimizing discriminatory attitudes are strongly recommended to promote HIV testing practice.

Sexual Behavior and Sexually Transmitted Infection Outcomes Among Men Who Have Sex With Men and Transgender Women Participating in a Study of the Timing of Antiretroviral Therapy in Lima, Peru

BACKGROUND

We assessed sexual behavior and incidence of sexually transmitted infections (STIs) among men who have sex with men and transgender women participating in Sabes, a study of an expanded treatment as prevention strategy focused on early diagnosis and treatment of HIV infection in Lima, Peru (2013-2017).

METHODS

Sabes participants were tested monthly for HIV to identify acute or early infections, and HIV-positive participants were randomized to receive antiretroviral therapy immediately (immediate arm) or after 24 weeks (deferred arm) during a 48-week follow-up period. Sexual behavior was assessed at randomization (baseline) and every 12 weeks thereafter. Participants were tested for urethral and rectal chlamydia and gonorrhea and for syphilis at baseline, 12, 24, and 48 weeks. We describe patterns of sexual behavior during the 48-week follow-up period and compare sexual behavior and STI incidence between study arms.

RESULTS

After randomization, 207 HIV-positive participants completed questionnaires and STI testing at 2 or more visits. After HIV diagnosis, participants in both arms reported increases in condom use with main and casual partners and decreased drug and alcohol use before or during anal sex. We observed no between-arm differences in sexual behavior. Deferred arm participants had higher incidence of chlamydia (incidence rate ratio, 2.33; 95% confidence interval, 1.14-4.77) but not gonorrhea or syphilis.

CONCLUSIONS

Despite reported increases in condom use, the overall high incidence of STIs reflects some ongoing condomless sex among HIV-positive men who have sex with men and transgender women, highlighting the importance of regular STI screening and counseling to support consistent condom use among HIV-positive individuals at risk for STIs.

Attitudes to disclosure of HIV-serostatus to new sexual partners and sexual behaviours among HIV-diagnosed gay, bisexual and other men who have sex with men in the UK

We assessed attitudes to disclosure to new sexual partners and association with sexual behaviours among HIV-diagnosed gay, bisexual, and other men who have sex with men (GBMSM) in the UK Antiretrovirals, Sexual Transmission Risk and Attitudes (ASTRA) study in 2011-12. Among 1373 GBMSM diagnosed with HIV for ≥3 months and reporting sex in the past three months (84% on antiretroviral therapy (ART), 75% viral load (VL) ≤50c/mL), 56.3% reported higher sexual disclosure ("agree" or "tend to agree" with "I'd expect to tell a new partner I'm HIV-positive before we have sex"). GBMSM on ART with self-reported undetectable VL had lower disclosure than those on ART without self-reported undetectable VL and those not on ART. Higher sexual disclosure was associated with higher prevalence of CLS in the past three months; this was due to its association with CLS with other HIV-positive partners. Higher sexual disclosure was more common among GBMSM who had CLS with other HIV-positive partners only (72.1%) compared to those who had higher-risk CLS with HIV-serodifferent partners (55.6%), other CLS with HIV-serodifferent partners (45.9%), or condom-protected sex only (47.6%). Findings suggest mutual HIV-disclosure and HIV-serosorting were occurring in this population. Knowledge of VL status may have impacted on disclosure to sexual partners.

HIV Testing and Risks of Sexual Behavior among HIV-Negative Men Who Have Sex with Men in Ningbo, China

Human immunodeficiency virus (HIV) testing is confirmed as a preventive strategy for HIV control. However, the testing rate and risk behaviors of HIV-negative men who have sex with men (MSM) remain unclear. We aimed to examine factors associated with HIV testing and high-risk behaviors among HIV-negative MSM. From July 2016 to June 2017, participants were recruited by snowball sampling from WeChat groups, bars, and other venues. HIV testing was performed to exclude HIV-positive MSM. Face-to-face questionnaires regarding HIV testing and high-risk behaviors were conducted; 988 MSM were included, and 57.1% of participants underwent HIV testing in the past year. The proportion of high-risk behaviors was 49.9%. Factors associated with HIV testing were bisexual orientation, substance use to adjust psychiatric disorders, and receiving acquired immune deficiency syndrome (AIDS) interventions. Being married, bisexual orientation, and receiving AIDS interventions were risk factors for high-risk sexual behaviors, while college or higher degree was a protective factor. We determined that HIV transmission factors are widespread, and the rate of HIV testing is relatively low. Attention should be given to marital status, using substances to adjust psychiatric disorders, or bisexual HIV-negative MSM, and AIDS interventions should be strengthened to promote HIV testing and reduce high-risk behaviors.

Genetic clustering analysis for HIV infection among MSM in Nigeria: implications for intervention

BACKGROUND

The HIV epidemic continues to grow among MSM in countries across sub-Saharan Africa including Nigeria. To inform prevention efforts, we used a phylogenetic cluster method to characterize HIV genetic clusters and factors associated with cluster formation among MSM living with HIV in Nigeria.

METHODS

We analyzed HIV-1 pol sequences from 417 MSM living with HIV enrolled in the TRUST/RV368 cohort between 2013 and 2017 in Abuja and Lagos, Nigeria. A genetically linked cluster was defined among participants whose sequences had pairwise genetic distance of 1.5% or less. Binary and multinomial logistic regressions were used to estimate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for factors associated with HIV genetic cluster membership and size.

RESULTS

Among 417 MSM living with HIV, 153 (36.7%) were genetically linked. Participants with higher viral load (AOR = 1.72 95% CI: 1.04-2.86), no female partners (AOR = 3.66; 95% CI: 1.97-6.08), and self-identified as male sex (compared with self-identified as bigender) (AOR = 3.42; 95% CI: 1.08-10.78) had higher odds of being in a genetic cluster. Compared with unlinked participants, MSM who had high school education (AOR = 23.84; 95% CI: 2.66-213.49), were employed (AOR = 3.41; 95% CI: 1.89-10.70), had bacterial sexually transmitted infections (AOR = 3.98; 95% CI: 0.89-17.22) and were not taking antiretroviral therapy (AOR = 6.61; 95% CI: 2.25-19.37) had higher odds of being in a large cluster (size > 4).

CONCLUSION

Comprehensive HIV prevention packages should include behavioral and biological components, including early diagnosis and treatment of both HIV and bacterial sexually transmitted infections to optimally reduce the risk of HIV transmission and acquisition.

Does HIV infection increase male sexual behavior?

After 40 years of intense study on HIV/AIDS, scientists have identified, among other things, at risk populations, stages of disease progression and treatment strategies. What has received less attention is the possibility that infection might elicit an increase in sexual behavior in humans. In 2000, Starks and colleagues speculated that HIV infection could alter host behavior in a manner that facilitated the spread of the virus. Retrospective and self-report data from five studies now support this hypothesis. Individuals with acute—versus nonacute—stage infections report more sexual partners and more frequent risky sex. Additionally, male sexual behavior increases nonlinearly with HIV viral load, and data suggest a potential threshold viral level above which individuals are more likely to engage in risky sexual behavior. Taken together, these data suggest that HIV infection influences male sexual behavior in a manner beneficial to the virus. Here, we present these findings, highlight their limitations and discuss alternative perspectives. We argue for increased testing of this hypothesis and advocate for increased public health measures to mitigate the putative impact on male sexual behavior.

Impact of early antiretroviral treatment on sexual behaviour: a randomised comparison

Background:

Antiretroviral treatment (ART) reduces HIV infectiousness but the effect of early ART on sexual behaviour is unclear.

Methods:

We assessed, within the START randomized trial that enrolled HIV-positive adults with CD4⁺ cell count greater than 500 cells/μl, the effect of early (immediate) versus deferred ART on: condomless sex with HIV-serodifferent partners (CLS-D); all condomless sex (CLS); HIV transmission-risk sex (CLS-D-HIV risk, defined as CLS-D and: not on ART or started ART <6 months ago or viral load greater than 200 copies/ml or no viral load in past 6 months), during 2-year follow-up. Month-12 CLS-D (2010–2014) was the primary outcome.

Results:

Among 2562 MSM, there was no difference between immediate and deferred arms in CLS-D at month 12 [12.6 versus 13.1%; difference (95% CI): −0.4% (−3.1 to 2.2%), P = 0.75] or month 24, or in CLS. Among 2010 heterosexual men and women, CLS-D at month 12 tended to be higher in the immediate versus deferred arm [10.8 versus 8.3%; difference:2.5% (−0.1 to 5.2%), P = 0.062]; the difference was greater at month 24 [9.3 versus 5.6%; difference: 3.7% (1.0 to 6.4%), P = 0.007], at which time CLS was higher in the immediate arm (20.7 versus 15.7%, P = 0.013). CLS-D-HIV risk at month 12 was substantially lower in the immediate versus deferred arm for MSM [0.2 versus 11%; difference: −10.7% (−12.5 to −8.9%), P < 0.001] and heterosexuals [0.6% versus 7.7%; difference: −7.0% (−8.8 to −5.3%), P < 0.001], because of viral suppression on ART.

Conclusion:

A strategy of early ART had no effect on condomless sex with HIV-serodifferent partners among MSM, but resulted in modestly higher prevalence among heterosexuals. However, among MSM and heterosexuals, early ART resulted in a substantial reduction in HIV-transmission-risk sex, to a very low absolute level.

Prevalence and protective factors of HIV and syphilis infection among men who have sex with men in Northwest China

BACKGROUND

Men who have sex with men (MSM) continue to be disproportionately impacted by human immunodeficiency virus (HIV) and syphilis in China. Little is known about HIV and syphilis infections among MSM in Xi'an, a developing city in Northwest China. A cross-sectional study with recruitment via snowball sampling was conducted to collect HIV and syphilis infection status and risk factors among MSM in Xi'an between April 2013 to December 2016. Among the 5000 participants, the mean age was 29.0 years (SD 7.7) and the prevalence of HIV, syphilis, and coinfection was 6.5%, 2.2%, and 0.4%, respectively. There was no significant change in HIV prevalence from 2013 to 2016, while the prevalence of syphilis and coinfection showed a downward trend. Multiple logistic regression analyses found that being over 25 years old (OR = 1.647), junior high school/middle school education and below (OR = 3.085), with a sexual role of passive or versatile (OR = 3.300; OR = 2.337), rush poppers use during the last 6 months (OR = 1.660) and syphilis infection (OR = 2.235) were more likely to acquire HIV infection, whereas used condoms in the last episode of anal sex (OR = 0.572) and tested HIV antibody previously (OR = 0.252) were protective factors for HIV infection. HIV prevalence among MSM in Xi'an was stable, whereas the prevalence of syphilis and coinfection showed a downward trend. Interventions to promote HIV and sexually transmitted disease testing and condom use should be strengthened, especially for MSM with low education.

HIV DNA Measurement and Improved Detection of HIV Infection Among Men Who Have Sex with Men: A Strategic Implication

Rapid test (RT) is the principal screening method in the HIV control practice. However, this method may lead to inaccurate detection, primarily due to the more than 4 weeks of window phase. In the present study, we performed a HIV DNA screening method to show its application prospects in men who have sex with men (MSM). From July 2017 to April 2018, we recruited 1,301 MSM from Beijing who were not previously diagnosed as HIV positive. Both HIV DNA detection and RT were performed. In total, 141 and 135 HIV-positive results were detected by DNA detection and RT, respectively. By repetitive and confirmative tests (Western blot), we verified that DNA detection detected 10 more true positives than RT and 4 false positives were corrected from RT. This represents 14 inaccurate RT results that were corrected by DNA measurement. Therefore, DNA measurement should be fully considered as a screening method in the detection of HIV among MSM in the future.

Undiagnosed HIV infections among gay and bisexual men increasingly contribute to new infections in Australia

Introduction

We determined the contribution of undiagnosed HIV to new infections among gay and bisexual men (GBM) over a 12‐year period in Australia where there has been increasing focus on improving testing and HIV treatment coverage.

Methods

We generated annual estimates for each step of the HIV cascade and the number of new HIV infections for GBM in Australia over 2004 to 2015 using relevant national data. Using Bayesian melding we then fitted a quantitative model to the cascade and incidence estimates to infer relative transmission coefficients associated with being undiagnosed, diagnosed and not on ART, on ART with unsuppressed virus, or on ART with suppressed virus.

Results

Between 2004 and 2015, we estimated the percentage of GBM with HIV in Australia who were unaware of their status to have decreased from 14.5% to 7.5%. During the same period, there was a substantial increase in the number and proportion of GBM living with HIV on treatment and with suppressed virus, with the number of virally suppressed GBM increasing from around 3900 (30.2% of all GBM living with HIV) in 2004 to around 14,000 (73.7% of all GBM living with HIV) in 2015. Despite the increase in viral suppression, the annual number of new infections rose from around 660 to around 760 over this period. Our results have a wide range due to the uncertainty in the cascade estimates and transmission coefficients. Nevertheless, undiagnosed GBM increasingly appear to contribute to new infections. The proportion of new infections attributable to undiagnosed GBM almost doubled from 33% in 2004 to 59% in 2015. Only a small proportion (<7%) originated from GBM with suppressed virus.

Discussion

Our study suggests that an increase in HIV treatment coverage in Australia has reduced the overall risk of HIV transmission from people living with HIV. However, the proportion of infections and the rate of transmission from undiagnosed GBM has increased substantially. These findings highlight the importance of HIV testing and intensified prevention for Australian GBM at high risk of HIV.

Changes of sexual risk behaviors and sexual connections among HIV-positive men who have sex with men along their HIV care continuum

BACKGROUND

While HIV incidence among men who have sex with men (MSM) is increasing in Hong Kong, unprotected sex apparently remains prevalent among those infected but virally non-suppressed. Little is known about how sexual behaviours and sexual connections may change among MSM along their HIV care continuum.

METHODS

In this retrospective cross-sectional study, HIV-positive MSM attending the largest HIV specialist clinic in Hong Kong between October and December 2014 were invited to complete a self-administrated structured questionnaire. Their behavioural profile and partner sourcing patterns during the one-year period respectively (a) before HIV diagnosis, (b) after HIV diagnosis, (c) after initiation of antiretroviral treatment and (d) preceding the survey were examined.

RESULTS

Of 345 recruited MSM, 304 (88.1%) had treatment initiated and 272 (78.8%) had viral load suppressed. In the first year after HIV diagnosis, the proportion reporting inconsistent condom use dropped from 47.0% to 17.5% (p<0.05) and from 49.6% to 17.8% (p<0.01) for anal sex with main and casual partners respectively. Except for mobile applications, usage of most sex-networking venues decreased significantly after diagnosis. Inconsistent condom usage rate remained at around 20% after treatment initiation and viral load suppression, but the frequency of use of sex-networking venues further varied among virally suppressed MSM.

CONCLUSIONS

Most HIV-positive MSM had persistently low level of sexual risk behaviours along their care continuum and achieved viral load suppression, conferring a general reduction of secondary transmission risk in Hong Kong. To increase the effectiveness of Treatment as Prevention strategy, uptake of HIV testing for undiagnosed HIV-positive MSM shall be emphasised.

High subsequent and recurrent sexually transmitted infection prevalence among newly diagnosed HIV-positive Thai men who have sex with men and transgender women in the Test and Treat cohort

We determined subsequent and recurrent sexually transmitted infections (STIs) among men who have sex with men (MSM) and transgender women (TGW) in the Test and Treat cohort. Thai MSM and TGW adults with previously unknown HIV status were enrolled and tested for HIV. Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and syphilis were tested at baseline, month 12, and month 24 to identify subsequent STIs (any STIs diagnosed after baseline) and recurrent STIs (any subsequent STIs diagnosed among those with positive baseline STIs). Among 448 participants, 17.8% were HIV-positive, the prevalence of subsequent STIs and recurrent STIs was 42% (HIV-positive versus HIV-negative: 66.3% versus 36.7%, p < 0.001) and 62.3% (81% versus 52.5%, p < 0.001), respectively. Common subsequent STIs by anatomical site were rectal CT infection (21.7%), rectal NG infection (13.8%), pharyngeal NG infection (13.1%), and syphilis (11.9%). HIV-positive status was associated with both subsequent STIs (adjusted hazard ratio [aHR] 2.38; 95%CI 1.64-3.45, p < 0.001) and recurrent STIs (aHR 1.83; 95%CI 1.16-2.87, p = 0.01). The results show that newly diagnosed HIV-positive MSM and TGW were at increased risk of STIs despite being in the healthcare system. STI educational counseling is necessary to improve STI outcomes among MSM and TGW in both HIV prevention and treatment programs.

Latent Classes of Sexual Risk Among Black Men Who Have Sex with Men and Women

Black men who have sex with men and women (BMSMW) are at high risk for HIV and other sexually transmitted infections (STIs). Despite knowing that HIV/STI risk varies by sexual positioning practices, limited data have characterized the risk profiles of BSMW. This study utilized latent class analysis (LCA) to explore BMSMW's sexual risk profiles regarding condomless sexual positioning practices. Participants were BMSMW in intervention studies in Los Angeles, Chicago, and Philadelphia. LCA was used to characterize their sexual risk profiles. Age, study location, HIV status, social support, and internalized homophobia were used as covariates in a multinomial regression model predicting the likelihood of class membership. Among the 546 participants, three latent classes of risk were identified: Seropositive Serosorters, Seronegative/unknown Serosorters, and Main Partners Only. All groups had the greatest probabilities of condomless sex with main partners. Seropositive Serosorters had the highest probabilities of condomless sex with HIV-positive partners. Seronegative/unknown Serosorters had the highest probabilities of condomless sex with HIV-negative or unknown status partners. HIV-positive BMSMW had 87% lower odds of being classified as Seronegative/unknown Serosorters than Seropositive Serosorters than HIV-negative/unknown status BMSMW (AOR = 0.13, 95% CI 0.06, 0.28). HIV-positive BMSMW had 71% lower odds of being classified as Main Partners Only than Seropositive Serosorters than HIV-negative/unknown status BMSMW (AOR = 0.29, 95% CI 0.16, 0.51). Findings highlight opportunities for clinicians to promote condom use and risk reduction among BMSMW with differing sexual risk profiles. Increased understanding of sexual positioning practices among BMSMW might help address HIV/STIs among this group.

Human Immunodeficiency Virus Partner Notification Services Among a Representative Sample of Young Black Men Who Have Sex With Men Demonstrates Limited Service Offering and Potential Benefits of Clinic Involvement

BACKGROUND

Partner notification (PN) is commonly offered to persons recently diagnosed with human immunodeficiency virus (HIV) to improve linkage to care and prevent onward transmission. Yet, much remains unknown about the factors associated with successful PN participation in populations at highest risk.

METHODS

Data were collected during the first 2 waves (2013-2015) of "uConnect," a population-based cohort study of young black men who have sex with men in Chicago (N = 618). Participants completed a biobehavioral survey and were tested for HIV. Among HIV-infected participants (N = 187), weighted logistic regression models examined the relationship between participant characteristics and being offered PN and providing partner names.

RESULTS

30.3% (n = 187) of the sample was HIV-positive, of which 71.7% (n = 134) were offered PN, including: 8.2% (n = 11) by the city health department; 51.5% (n = 69) by health care providers; and 40.3% (n = 54) by both. Being offered PN was significantly associated with criminal justice involvement history (adjusted odds ratio [aOR], 2.49; 95% confidence interval [CI], 1.38-4.49), volatile nitrates usage (aOR, 2.88; 95% CI, 1.20-6.94), and recent conversations with HIV outreach workers (aOR, 2.68; 95% CI, 1.25-5.77). Providing partner names was significantly associated with intermittent (aOR, 7.26; 95% CI, 1.75-30.07) and heavy (aOR, 11.47; 95% CI, 2.57-51.22) marijuana use, and being offered PN by both the city health department and health care provider (aOR, 8.36; 95% CI, 2.73-25.62).

CONCLUSIONS

A substantial proportion of HIV-diagnosed individuals were never offered PN. Being offered PN by multiple sources is associated with participation, and improved collaboration within health systems may improve participation rates.

"An Evil Lurking Behind You": Drivers, Experiences, and Consequences of HIV-Related Stigma Among Men Who Have Sex With Men With HIV in Manila, Philippines

The Philippines has a rapidly growing HIV epidemic, with men who have sex with men (MSM) accounting for a majority of known cases. Currently, there is little understanding about MSM's experiences of HIV-related stigma in the Philippines and how they influence behavior and quality of life. Twenty-one interviews with MSM living with HIV and with communitybased organization workers were conducted in Manila from June to August 2017. MSM participants were affected by the intersection of HIV-related stigma and stigma toward homosexuality that are rooted in connotations of morality, "dirtiness," and sin. We identified specific patterns by which MSM living with HIV experienced enacted, felt, and internalized stigma and discuss implications of stigma for mental health, delays in HIV testing, and avoidance of HIV health services. Findings support the development of public health strategies in the Philippines that address stigma at societal and individual levels to reduce stigma-related harms.

Acceptability of Peer-Delivered HIV Testing and Counselling Among Men Who Have Sex with Men (MSM) and Transgender Women (TW) in Myanmar

Men who have sex with men (MSM) and transgender women (TW) are a priority population for HIV prevention in Myanmar but report sub-optimal HIV testing frequency. Previous studies have shown that peer involvement in HIV testing can normalize stigmatized sexualities and reduce barriers to testing. We explored the acceptability of peer-delivered HIV testing among 425 undiagnosed MSM and TW in Yangon and Mandalay. An overwhelming majority of participants (86%) reported being 'comfortable/very comfortable' with peer-delivered HIV testing. Logistic regression identified reporting sexual identity as Apone [adjusted odds ratio (aOR) 3.8; 95% CI 1.2-11.7], recent HIV testing (aOR 3.1; 95% CI 1.4-6.5), reporting a high likelihood of HIV acquisition (aOR 3.6; 95% CI 1.7-7.6), and reporting ≥ 5 casual partners in the past 3 months (aOR 0.2; 95% CI 0.1-0.6) as associated with peer-delivered HIV testing acceptability. Given ongoing HIV vulnerability among MSM and TW in Myanmar, peer-delivered testing may offer prevention benefits by increasing testing rates and identifying undiagnosed infection earlier.

A workforce in jeopardy: identifying the challenges of ensuring a sustainable advanced HIV nursing workforce

Background

HIV services in England face substantial challenges arising from financial pressures and changes to commissioning. A sustainable HIV specialist nursing workforce will be vital to enable them to respond to those challenges.

Aims

This paper examines the current workforce situation in HIV services across the country.

Methods

This mixed-method study involved semi-structured interviews with 19 key stakeholders and with 44 nurses/physicians from 21 purposively selected HIV services across England. Data were interpreted using a framework analysis approach.

Results

'Building a career in HIV nursing' identified problems associated with retention and recruitment. Changes in commissioning are disrupting common career routes from sexual health to HIV nursing, and a perceived lack of a clear career pathway was seen as a barrier to recruitment. 'Developing a specialist workforce' explored the professional development of the current workforce, which was hampered by poor access to funding or study time for advanced study and the absence of an HIV-specific advanced nursing qualification.

Conclusions

The HIV nursing workforce, which provides an increasing proportion of HIV care, is facing serious recruitment and retention challenges. A strategic approach to workforce development and training is essential to overcome systemic barriers and secure the next generation of skilled practitioners.

Meta-Analysis of Alcohol and Serodiscordant Condomless Sex Among People Living with HIV

While observational studies have found that alcohol consumption is associated with serodiscordant condomless sex among people living with HIV (PLHIV), no meta-analysis has yet examined this trend. We conducted a meta-analysis to synthesize empirical evidence on the association between alcohol and condomless sex with partners at risk of HIV acquisition. To meet inclusion criteria, studies: (1) specifically targeted PLHIV or provided stratified data for HIV-infected participants; (2) provided a quantitative measure of alcohol use; (3) provided a quantitative measure of condomless sex with serodiscordant partners; and (4) reported the results of statistical tests examining the relationship between alcohol use and serodiscordant condomless sex. Using random-effects models, weighted effect sizes were calculated. Three separate analyses were conducted to examine serodiscordant condomless sex in association with any alcohol consumption, binge/problematic drinking, and alcohol in a sexual context. A total of 36 independent effect sizes from 27 studies (including 25,065 HIV-infected participants) were pooled in the meta-analysis. Any alcohol consumption, binge/problematic drinking, and alcohol use in a sexual context were each associated with condomless sex with serodiscordant partners [OR 1.64 (95% CI 1.46-1.85); OR 1.65 (95% CI 1.14-2.39); OR 2.88 (95% CI 2.01-4.12), respectively]. Meta-analytic findings demonstrate a consistent positive relationship between alcohol use and serodiscordant condomless sex among PLHIV. Future public health programming for HIV-infected individuals needs to address the role of alcohol consumption in sexual risk-taking behavior.

Sexualised drug use in the United Kingdom (UK): A review of the literature

BACKGROUND

Sexualised drug use (SDU) refers to the use of drugs in a sexual context. This includes 'Chemsex'- the use of drugs (specifically crystal methamphetamine, GHB/GBL and mephedrone) before or during planned sexual activity to sustain, enhance, disinhibit or facilitate the experience. Here we aimed to synthesise available UK prevalence data for Chemsex, SDU and the use of Chemsex drugs in an undefined context (CDU) in men who have sex with men (MSM).

METHODS

Papers published between January 2007 and August 2017 reporting Chemsex, SDU and/or Chemsex drug use (CDU) prevalence in MSM were identified through PubMed. Citations were searched for further eligible publications. We also conducted a review of national surveillance data, extracting prevalence data for Chemsex, SDU or CDU. Synthesized data were then assessed to determine the time at which these drugs were taken, in this case just prior to or during sexual activity (event-level).

RESULTS

Our search identified 136 publications, of which 28 were included in the final data synthesis. Three of the four surveillance systems assessed provided SDU or CDU data in MSM. Few publications included event-level data for Chemsex (n = 4), with prevalence estimates ranging from 17% among MSM attending sexual health clinics (SHC) to 31% in HIV-positive MSM inpatients. Prevalence estimates for SDU (n = 7 publications) also varied considerably between 4% in MSM receiving HIV care to 41% among MSM attending SHC for HIV post-exposure prophylaxis (PEP). Eighteen publications provided data for CDU.

CONCLUSION

Prevalence estimates varied considerably due to differences in the definition used and population assessed. Standardised definitions and studies with representative national samples of MSM are required to improve our understanding of the extent of Chemsex and its associated risks. Longitudinal event-level data for SDU and Chemsex are needed to monitor impact of interventions.

Prosecution of non-disclosure of HIV status: Potential impact on HIV testing and transmission among HIV-negative men who have sex with men

Background

Non-disclosure criminal prosecutions among gay, bisexual and other men who have sex with men (MSM) are increasing, even though transmission risk is low when effective antiretroviral treatment (ART) is used. Reduced HIV testing may reduce the impact of HIV “test and treat” strategies. We aimed to quantify the potential impact of non-disclosure prosecutions on HIV testing and transmission among MSM.

Methods

MSM attending an HIV and primary care clinic in Toronto completed an audio computer-assisted self-interview questionnaire. HIV-negative participants were asked concern over non-disclosure prosecution altered their likelihood of HIV testing. Responses were characterized using cross-tabulations and bivariate logistic regressions. Flow charts modelled how changes in HIV testing behaviour impacted HIV transmission rates controlling for ART use, condom use and HIV status disclosure.

Results

150 HIV-negative MSM were recruited September 2010 to June 2012. 7% (9/124) were less or much less likely to be tested for HIV due to concern over future prosecution. Bivariate regression showed no obvious socio/sexual demographic characteristics associated with decreased willingness of HIV testing to due concern about prosecution. Subsequent models estimated that this 7% reduction in testing could cause an 18.5% increase in community HIV transmission, 73% of which was driven by the failure of HIV-positive but undiagnosed MSM to access care and reduce HIV transmission risk by using ART.

Conclusions

Fear of prosecution over HIV non-disclosure was reported to reduce HIV testing willingness by a minority of HIV-negative MSM in Toronto; however, this reduction has the potential to significantly increase HIV transmission at the community level which has important public health implications.

Care continuum entry interventions: seek and test strategies to engage persons most impacted by HIV within the United States

: The current review re-conceptualizes seek and test strategies, particularly given the changing importance of HIV testing as care continuum entry for persons irrespective of their HIV status. Care continuum entry advances previous seek and test strategies for client engagement with two next-generation functions: use of testing to engage (or re-engage) HIV negative clients in preexposure prophylaxis (PrEP) care; and testing individuals who may already be known positives for care continuum re-entry. We review existing seek and test strategies for most impacted community members with a goal of optimizing care continuum entry as we move towards HIV transmission elimination. These strategies are context, sub-group, community and epidemic-specific. This review is timely, given the initiation of routine PrEP care, which shifts and broadens our conceptualization of care continuum entry triggered by the HIV testing event. In addition, as the epidemic becomes more concentrated, focusing on re-engagement of HIV-infected persons becomes increasingly important given that transmission events involve both those acutely and newly infected as well as the large numbers who may not be virally suppressed. We start with examination of routine testing in healthcare settings, emphasizing its potential role in re-engagement for persons out of care. Subsequently, we describe risk-based testing to identify key populations. We then review network-based approaches and their impact on the epidemic. We close with future directions for individual and combination care continuum entry strategies most relevant to elimination of HIV transmission in the United States.

A systematic review of psychological correlates of HIV testing intention

Undiagnosed HIV infection is associated with onward HIV transmission and delays in accessing HIV care and treatment. As a significant proportion of HIV tests are self-initiated, it is important to assess correlates of the intention to test for HIV. Psychological correlates of HIV testing intention are more likely to be the feasible target of interventions than structural determinants. A systematic review of psychological correlates of HIV testing intention was conducted. Twenty studies were included in the review, covering a range of populations and geographical regions. The most commonly assessed variables were HIV risk perception and HIV knowledge rather than HIV test-specific psychological factors. There was evidence that HIV risk perception and pro-testing attitudes were consistently associated with HIV testing intention across a number of studies. There is a need for longitudinal designs, including experimental studies, allowing for more confident casual inferences to be made. Theoretical, research and practice implications are outlined.

Opt-Out Referral of Men Who Have Sex With Men Newly Diagnosed With HIV to Partner Notification Officers: Results and Yield of Sexual Partners Being Contacted

BACKGROUND

Given its potential for reducing the proportion of people with human immunodeficiency virus (HIV) unaware of their diagnosis, partner notification for HIV has been underutilized. This study aimed to determine if the implementation of opt-out referral of men who have sex with men, newly diagnosed with HIV, to partner notification officers (PNO) increased the proportion of sexual partners notified.

METHODS

In April 2013, all individuals newly diagnosed with HIV at the Melbourne Sexual Health Centre, Australia were referred to Department of Health PNO to facilitate partner notification. The number of sexual partners reported by men and the proportion contacted in the 12 months before (opt-in period) and after (opt-out period) this policy change were determined through review of the clinical PNO records.

RESULTS

Overall, 111 men were diagnosed with HIV during the study period. Compared with men in the opt-in period (n = 51), men in the opt-out period (n = 60) were significantly more likely to accept assistance from the PNO (12 [24%] vs 51 [85%]; P < 0.001). A significantly higher proportion of reported partners were notified with opt-out referral (85/185, 45.9%; 95% confidence interval, 38.6-53.4) compared with opt-in referral (31/252, 12.3%; 95% confidence interval, 8.5-17.0) (P < 0.001).

DISCUSSION

Opt-out referral to PNO was associated with a substantially higher proportion of partners at risk of HIV being contacted.

The role of frequent HIV testing in diagnosing HIV in men who have sex with men

OBJECTIVES

In the UK, quarterly HIV testing is recommended for high-risk men who have sex with men (MSM). In this manuscript we determined the risk of being newly diagnosed with HIV in MSM by their HIV testing history, considering both the frequency and periodicity of testing.

METHODS

Data on HIV incidence in MSM attending a sexual health clinic (SHC) in England in 2013-2014 with testing history (previous 2 years) were obtained from GUMCAD, the national sexually transmitted infection (STI) surveillance system in England. HIV testing patterns among MSM were defined using the frequency and periodicity of testing, based on 3 month intervals, in the year preceding the first attendance during the study period. Cox proportional hazards regression was used to determine the association between HIV testing pattern and time to HIV diagnosis with and without adjustment for demographic confounders. Analyses were stratified by risk stratum, with 'high risk' defined as a history of a bacterial STI in the past year. Adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) are reported.

RESULTS

Among the 37 702 HIV-negative MSM attending an SHC in 2013-2014, 1105 (3%) were diagnosed with HIV infection within 1 year of their first attendance. The probability of HIV diagnosis was highest in MSM who were tested quarterly compared with those who were not tested in the past year (aHR 2.51; 95% CI 1.33-4.74); this increased 1.8-fold among high-risk MSM (aHR 4.48; 95% CI 0.97-21.17).

CONCLUSIONS

The probability of subsequent HIV diagnosis was greatest in high-risk MSM who were tested most frequently. Quarterly HIV testing increased the likelihood of identifying undiagnosed HIV infection and should remain a continued recommendation for high-risk MSM.

Disclosure of newly diagnosed HIV infection and condom use at first sex after diagnosis: a study of young Black men who have sex with men

Background The first purpose of the present study was to determine whether young Black men who have sex with men (YBMSM) disclose their newly diagnosed HIV infection to a male or female partner, and to determine whether this disclosure is related to condom use; the second was to identify correlates of disclosing newly diagnosed HIV infection to male sex partners, including a measure of partner-related barriers to condom use.

METHODS

A sample of 125 HIV-infected YBMSM (age 15-29 years) provided cross-sectional data used for both study purposes. Recruitment occurred in a mid-size city in the southern US experiencing inordinately high prevalence and incidence rates of HIV among YBMSM. Significance was defined by an α level of <0.05.

RESULTS

Eighty-eight YBMSM (70.4%) indicated disclosing their newly diagnosed HIV status to the first male partner they had sex with after being diagnosed. Of these, nine (9.1%) reported that condoms were not used during ensuing sex with that partner. However, of the men not disclosing, 27.0% reported not using condoms for ensuing sex (P=0.009). Similar findings were observed relative to sex with females (P=0.057). Regarding the second study purpose, in addition to a protective effect of advancing age, men scoring at or above the median on a measure of partner-related barriers to condom use were 2.4-fold more likely to not disclose compared with men scoring below the median (P=0.04).

CONCLUSION

For YBMSM, a beneficial counselling objective relative to disclosing newly diagnosed HIV may be to help men resolve perceptions of partner-related barriers to condom use.

Pilot RCT Results of an mHealth HIV Prevention Program for Sexual Minority Male Adolescents

BACKGROUND

Guy2Guy (G2G) is the first comprehensive HIV prevention program developed for sexual minority males as young as 14 years old and is delivered nationally via text messaging. Here, we report the results of the pilot randomized control trial.

METHODS

G2G was tested against an attention-matched "healthy lifestyle" control (eg, self-esteem). Both programs lasted 5 weeks and delivered 5 to 10 text messages daily. A 1-week booster was delivered 6 weeks subsequently. Participants were cisgender males ages 14 to 18 years old who were gay, bisexual, and/or queer and had an unlimited text messaging plan. Youth were recruited across the United States via Facebook and enrolled by telephone from October 2014 to April 2015. Ninety-day postintervention outcomes were condomless sex acts (CSA) and abstinence and, secondarily, HIV testing. We also examined these outcomes at intervention end and stratified them by sexual experience.

RESULTS

At 90 days postintervention, there were no significant differences in CSAs or abstinence noted. Among participants who were sexually active at baseline, intervention participants were significantly more likely to report getting an HIV test (adjusted odds ratio = 3.42, P = .001). They were also less likely than control youth to be abstinent (adjusted odds ratio = 0.48, P = .05). CSAs were significantly lower for those in the intervention versus control at intervention end (incident rate ratio = 0.39, P = .04), although significance was lost once age was added to the analysis (incident rate ratio = 0.58, P = .26).

CONCLUSIONS

G2G appears promising in increasing adolescent HIV testing rates. Sex-positive intervention messages appear to have increased the participants' comfort with having sex (ie, less abstinence) while not increasing their potential for HIV transmission (ie, more CSAs). Additional content or features may be needed to invigorate condom use.

A Qualitative Assessment of Alcohol Consumption and Sexual Risk Behaviors Among Men Who Have Sex With Men and Transgender Women in Peru

BACKGROUND

Peruvian men who have sex with men (MSM) and transgender women (TGW) experience the double burden of a highly concentrated HIV epidemic with a high prevalence of alcohol use disorders (AUDs). Recent research has associated both with risky sexual behaviors, including unprotected sex, having multiple sexual partners, engaging in sex work, having recent sexually transmitted infections, and having HIV-infected partners. AUDs have also been associated in MSM/TGW with being unaware of HIV+ status.

OBJECTIVES

This study aims to further examine issues associated with alcohol consumption, HIV infection, and risk behaviors in a qualitative analysis of focus groups conducted with MSM/TGW in Peru.

METHODS

A total of 26 MSM/TGW participants with AUDs participated in three semi-structured focus groups in Lima, Peru. Content analysis was facilitated by software, and specific themes were elucidated.

RESULTS

Participants described their drinking patterns, including the types of alcoholic drinks they consumed. They depicted drinking frequently and over multiple-day sessions. Problematic drinking behaviors were described, as well as the perceived characteristics of alcohol dependence. Interestingly, HIV-infected participants who were prescribed antiretroviral therapy did not believe that their drinking affected their medication adherence. These insights can aid in the design of future interventions aiming to reduce problematic drinking as well as HIV-related risk behaviors and, subsequently, HIV incidence.

CONCLUSIONS

Peruvian MSM/TGW exhibit problematic drinking, which may be associated with risky sexual behaviors and HIV transmission. Interest in reducing alcohol consumption was high, suggesting the need for targeted behavioral and pharmacological interventions.

Changes in Condomless Sex and Serosorting Among Men Who Have Sex With Men After HIV Diagnosis

BACKGROUND

Among men who have sex with men (MSM) diagnosed with HIV, high-risk sexual behaviors may decline in the year after diagnosis. The sustainability of these changes is unknown.

METHODS

We created a retrospective cohort (Seroconversion Cohort) of MSM attending an STD clinic in Seattle, Washington who tested HIV positive between 2001 and 2013 and had a negative HIV test <2 years before diagnosis. We randomly selected 1000 HIV-negative controls (men who always tested HIV negative) who were frequency-matched to the Seroconversion Cohort based on HIV diagnosis year. 12-month sexual behavior data were collected at each clinic visit. We examined condomless anal intercourse (CAI) with HIV-negative, HIV-positive, and HIV unknown-status partners before diagnosis and up to 4 years thereafter.

RESULTS

Of the 26,144 clinic visits where MSM tested for HIV, there were 655 (2.5%) new HIV diagnoses. Of these, 186 (28%) men had previously tested HIV negative and were included in the Seroconversion Cohort. The proportion (of the 186) reporting CAI with HIV-negative partners declined from 73% at diagnosis to 12% after diagnosis (P < 0.001), whereas CAI with HIV-positive partners increased (11%-67%; P < 0.001). The proportion who serosorted (ie, CAI only with HIV-concordant partners) did not change before or after diagnosis (34%-40%; P = 0.65). These 3 behaviors remained stable for up to 4 years after diagnosis. Among HIV-negative controls, serosorting and CAI with HIV-positive and HIV-negative partners was constant.

CONCLUSIONS

MSM substantially modify their sexual behavior after HIV diagnosis. These changes are sustained for several years and may reduce HIV transmission to HIV-uninfected men.

Impact of Peer Support on Behavior Change Among Newly Diagnosed Australian Gay Men

INTRODUCTION

Treatment as prevention relies on early uptake of HIV treatment, but onward transmission during primary HIV infection may be affected by changes in sexual risk behavior after diagnosis. What factors are associated with these changes in sexual risk behavior among gay and bisexual men?

METHODS

We surveyed gay and bisexual men recently diagnosed with HIV about changes to their sexual behavior since their diagnosis. In 2008-2010, 263 men described their sexual behavior during the 4 weeks before, and during the 4 weeks after, their HIV diagnosis. In 2010-2015, 301 men reported how they had changed their sexual behavior since their HIV diagnosis.

RESULTS

During 2008-2010, 26.6% engaged in condomless anal intercourse with non-HIV-positive casual partners during the 4 weeks before diagnosis, and 9.7% did so during the 4 weeks after diagnosis (P < 0.001). Only peer support from other people with HIV was associated with this change in behavior (OR = 1.42; 95% confidence interval = 1.07 to 1.88; P = 0.014). Peer support was also associated with partner reduction after diagnosis (P = 0.010). During 2010-2015, 31.9% reported that they had increasingly disclosed their HIV status to sex partners since their diagnosis, and 74.1% reported having reduced the number of men with whom they had sex. Peer support was associated with both these changes in behavior (P = 0.003 and P = 0.015, respectively).

CONCLUSIONS

The risk of onward transmission is likely to be less affected by immediate versus early treatment than it is by earlier diagnosis and peer support for those newly diagnosed with HIV. Enhanced peer support may further reduce the likelihood of onward transmission after diagnosis.

Significant association between perceived HIV related stigma and late presentation for HIV/AIDS care in low and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Late presentation for human immunodeficiency virus (HIV) care is a major impediment for the success of antiretroviral therapy (ART) outcomes. The role that stigma plays as a potential barrier to timely diagnosis and treatment of HIV among people living with HIV/AIDS (acquired immunodeficiency syndrome) is ambivalent. This review aimed to assess the best available evidence regarding the association between perceived HIV related stigma and time to present for HIV/AIDS care.

METHODS

Quantitative studies conducted in English language between 2002 and 2016 that evaluated the association between HIV related stigma and late presentation for HIV care were sought across four major databases. This review considered studies that included the following outcome: 'late HIV testing', 'late HIV diagnosis' and 'late presentation for HIV care after testing'. Data were extracted using a standardized Joanna Briggs Institute (JBI) data extraction tool. Meta- analysis was undertaken using Revman-5 software. I2 and chi-square test were used to assess heterogeneity. Summary statistics were expressed as pooled odds ratio with 95% confidence intervals and corresponding p-value.

RESULTS

Ten studies from low- and middle- income countries met the search criteria, including six (6) and four (4) case control studies and cross-sectional studies respectively. The total sample size in the included studies was 3,788 participants. Half (5) of the studies reported a significant association between stigma and late presentation for HIV care. The meta-analytical association showed that people who perceived high HIV related stigma had two times more probability of late presentation for HIV care than who perceived low stigma (pooled odds ratio = 2.4; 95%CI: 1.6-3.6, I2 = 79%).

CONCLUSIONS

High perceptions of HIV related stigma influenced timely presentation for HIV care. In order to avoid late HIV care presentation due the fear of stigma among patients, health professionals should play a key role in informing and counselling patients on the benefits of early HIV testing or early entry to HIV care. Additionally, linking the systems and positive case tracing after HIV testing should be strengthened.
