Leveraging social networks to expand HIV self-testing among culturally diverse MSM in Australia
Background: HIV self-testing (HIVST) can help overcome barriers to clinic-based testing among men who have sex with men (MSM). Peer-led distribution through existing social networks may further extend reach and acceptability. Objective: Guided by the Consolidated Framework for Implementation Research (CFIR), this study evaluated a social network-based HIVST intervention in Australia, in which "test promoters" distributed HIVST kits to friends and…
HIV Self-Test Program Preferences Among Non-Hispanic Black and Hispanic Men Who Have Sex with Men in the Southern United States
Non-Hispanic Black and Hispanic men who have sex with men (BHMSM) in the Southern United States (US) have the highest rates of new HIV diagnoses in the country. Self-testing can increase detection and contribute to decreasing diagnoses, but it is unclear which self-test program characteristics encourage the highest engagement. To inform the design of self-test programs, we conducted an online discrete choice experiment with BHMSM in this region w…
It’s Not Secret—It’s Not Advertised” – Content, Format, and Platform Preferences to Promote PrEP Use in the Southern United States
Gay, bisexual, and other men who have sex with men (GBM) in the Southern United States (US) experience high HIV incidence yet have relatively lower HIV pre-exposure prophylaxis (PrEP) uptake, especially among GBM of color. Despite awareness, PrEP use remains insufficient to meaningfully impact the HIV epidemic in the Southern US. PrEP promotions largely focus on PrEP messaging, especially product awareness. Theory-based health promotion research …
Evaluation of artificial intelligence (AI) chatbots for providing sexual health information
Prompt-tuned AI chatbots demonstrated superior performance in providing sexual health information compared to base ChatGPT, with high safety scores particularly noteworthy. However, all AI chatbots showed susceptibility to generating incorrect information. These findings suggest the potential for AI chatbots as adjuncts to human healthcare providers for providing sexual health information while highlighting the need for continued refinement and h…
Identifying subgroups of Chinese men who have sex with men based on sexual behavior and drug use patterns using a clustering analysis approach
SDU is a stratum for identifying MSM subgroups, and MSM who reported SDU demonstrated higher sexual risk behaviors and PrEP usage. Among those not practicing SDU, self-masturbation is a key behavioral indicator for subgrouping
Anxiety responses and testing intentions among gay and bisexual men using an AI-powered HIV/STI risk assessment tool
While MySTIRisk increased anxiety in some users, it maintained high acceptability and did not deter testing intentions. These findings support implementing such tools with appropriate anxiety management strategies

Determinants and prediction of Chlamydia trachomatis re-testing and re-infection within 1 year among heterosexuals with chlamydia attending a sexual health clinic
Background: (chlamydia) is one of the most common sexually transmitted infections (STI) globally, and re-infections are common. Current Australian guidelines recommend re-testing for chlamydia 3 months after treatment to identify possible re-infection. Patient-delivered partner therapy (PDPT) has been proposed to control chlamydia re-infection among heterosexuals. We aimed to identify determinants and the prediction of chlamydia re-testing and re…
Preferences for HIV prevention strategies among newly arrived Asian-born men who have sex with men living in Australia
The HIV epidemic in Australia is changing with higher risk for HIV among newly-arrived Asian-born men who have sex with men (MSM) compared to Australian-born MSM. We evaluated the preferences for HIV prevention strategies among 286 Asian-born MSM living in Australia for <5 years. A latent class analysis uncovered three classes of respondents who were defined by their preferences: “PrEP” (52%), “Consistent condoms” (31%), and “No strategy” (17%). …
ESexualHealth
Objectives: Gay, bisexual and other men who have sex with men (GBMSM) and trans and gender diverse (TGD) people are disproportionately affected by poorer sexual health outcomes compared to heterosexual populations. We aimed to explore the preferences of GBMSM and TGD for using eHealth for sexual health (eSexualHealth). Methods: We distributed an anonymous online survey from April to August 2021among the lesbian, gay, bisexual, transgender, inters…
Pay-it-forward influenza vaccination among older adults and children
A quasi-experimental study was conducted to evaluate the effectiveness of a pay-it-forward strategy for increasing influenza vaccination among children and older adults compared to a self-paid vaccination strategy in China. Pay-it-forward is an innovative community-engaged intervention in which participants receive a free influenza vaccination and are then asked if they would like to donate or create a message to support subsequent vaccinations. …
Cost-effectiveness of Hepatitis C virus self-testing in four settings
Globally, there are approximately 58 million people with chronic hepatitis C virus infection (HCV) but only 20% have been diagnosed. HCV self-testing (HCVST) could reach those who have never been tested and increase uptake of HCV testing services. We compared cost per HCV viraemic diagnosis or cure for HCVST versus facility-based HCV testing services. We used a decision analysis model with a one-year time horizon to examine the key drivers of eco…

We collected the following sexual activities: tongue-kissing, penises touching, using saliva during mutual masturbation, performed rimming, received rimming, performed fellatio, received fellatio, insertive anal sex, and …
Prevalence of and Characteristics Associated with Use Of Withdrawal Among Women in Victoria, Australia
Withdrawal use is common, but there is a need for better education on proper use. Health professionals should discuss the risks and benefits of withdrawal, along with those of other methods, when discussing con-traception with their patients. Further research is needed into why women choose withdrawal
Contraception matters
Despite reported high contraceptive usage, nearly 40% of women were at risk for unintended pregnancy primarily due to inconsistent contraceptive use and use of ineffective contraception. Strategies for improving consistency of effective contraception use or greater emphasis on long-acting contraception may be needed for certain subpopulations at higher risk for unintended pregnancy
Prevalence of and Characteristics Associated with Use Of Withdrawal Among Women in Victoria, Australia
Withdrawal use is common, but there is a need for better education on proper use. Health professionals should discuss the risks and benefits of withdrawal, along with those of other methods, when discussing con-traception with their patients. Further research is needed into why women choose withdrawal
Exploring anal self-examination as a means of screening for anal cancer in HIV positive men who have sex with men
ASE may be an acceptable means for anal cancer detection in HIV-positive MSM but training in detecting abnormalities is needed. The preference for health professional examination and inadequate physical flexibility may preclude its use for some men. Future trials to confirm its wider acceptability will be needed before undertaking an effectiveness trial for detecting anal cancer
Why are we not screening for anal cancer routinely - HIV physicians’ perspectives on anal cancer and its screening in HIV-positive men who have sex with men
HIV physicians remain ambivalent regarding the most effective means to screen for anal cancer. More research is needed to address the physicians' concerns before anal cancer screening can be implemented into routine HIV care
Receiving HIV Serostatus Disclosure from Partners Before Sex
No Place Like Home? Disentangling Preferences for HIV Testing Locations and Services Among Men Who Have Sex with Men in China
In China, some health departments and gay community-based organizations have begun to offer home-based HIV testing kits in order to augment test uptake among men who have sex with men (MSM). However, HIV test preferences and motivations for home-testing among MSM in China are not well understood. The HIV testing preferences of 803 MSM throughout China were evaluated using single-item assessment and a discrete choice experiment (DCE). In both the …
Supernatural explanatory models of health and illness and healthcare use in China among men who have sex with men
People's beliefs in supernatural explanatory models of health and illness - beliefs in divine and/or supernatural forces to inform how they perceive, interpret, and respond to health and illness - may have important implications for their use of healthcare services, especially among individuals with lower socioeconomic status (SES). However, the relevance of such research for contexts with strong Confucian and Buddhist traditions and sexual minor…
Driving force of condomless sex after online intervention among Chinese men who have sex with men
The intervention appeared to be effective among MSM who reported viewing additional condom promotion videos by themselves and more community engagement after the intervention. In MSM who reported risky sexual behaviors at baseline, the intervention appeared less effective. Tailored intervention videos that target particular subgroups, active in-person community engagement, and optimized intervention frequency should be considered in future sexual…

The objective of this study was to examine the impact of the Australian COVID-19 lockdown restrictions on access to antiretroviral therapy (ART) for people living with HIV in Melbourne. Using data from the Melbourne Sexual Health Centre (MSHC), we assessed the changes in rates of ART postal delivery, controlled viral load, and ART dispensing …
Comparing HIV Post-Exposure Prophylaxis, Testing, and New Diagnoses in Two Australian Cities with Different Lockdown Measures during the Covid-19 Pandemic
Australia introduced a national lockdown on 22 March 2020 in response to the COVID-19 pandemic. Melbourne, but not Sydney, had a second COVID-19 lockdown between July and October 2020. We compared the number of HIV post-exposure prophylaxis (PEP) prescriptions, HIV tests, and new HIV diagnoses during these lockdown periods. The three outcomes in 2020 were compared to 2019 using incidence rate ratio. There was a 37% and 46% reduction in PEP prescr…
Examining potential effects of non-occupational post-exposure prophylaxis (nPEP) on sexual behaviors of Chinese men who have sex with men
These findings identify a high-risk subgroup of MSM, who reported they would use condoms less and/or have more sexual partners when nPEP becomes available. This subgroup of MSM might benefit from targeted health interventions. Moreover, there is a clear discrepancy between anticipated individual and population behavioral changes regarding future routinization of nPEP services, suggesting incorporating nPEP services as a means of community develop…
Young people’s preferences for HIV self-testing services in Nigeria
HIV self-testing preferences among Nigerian youth appear to be influenced by several factors including lower cost, less invasive testing method, location of testing, and linkage to care and support post testing. Findings underscore the need to address young people's HIV self-testing preferences as a foundation for implementing programs and research to increase the uptake of HIVST
The duration and body position during tongue-kissing among heterosexual men and women

We aim to examine the duration or body position of heterosexual men and women during tongue-kissing (henceforth, known as kissing). Methods A cross-sectional survey among heterosexual men and women attending the Melbourne Sexual Health Centre in Australia between May 2019 and March 2020 collected data on the duration and body position (i.e., on top of or lying down underneath…
HCV Self-Testing to Expand Testing
Background: Hepatitis C virus self-testing (HCVST) may increase test uptake especially among marginalized key populations such as men who have sex with men (MSM). We conducted an observational study to assess the usability, acceptability and feasibility of HCVST among MSM in China. Methods: An observational study with convenience sampling was performed among MSM in Guangzhou, China in 2019. The OraQuick® HCV Rapid Antibody Test kits were used in …
“How PrEPared are you?”
Introduction: Overseas-born and newly arrived gay and bisexual men and men who have sex with men (GBMSM) are at higher risk of acquiring HIV in comparison to Australian-born GBMSM. Pre-exposure prophylaxis (PrEP) is subsidized by the Australian government under Medicare, Australia's universal health insurance scheme, however many members of this population are Medicare-ineligible, which could prevent them from accessing PrEP. We wanted to explore…

Sexualized Drug Use Among Female Sex Workers from Eight Cities in China
There is a rich literature on sexualized drug use (i.e., drug use before or during sex) for men who have sex with men but less data from female sex workers (FSW), particularly from low- and middle-income countries. We describe the sexual and reproductive health outcomes in FSW reporting sexualized drug use. In 2019, we conducted a cross-sectional study in eight cities from seven provinces in China. We recruited FSW through community organizations…
Improving Access to Sexual Health Services in General Practice Using a Hub-and-Spoke Model
Improving access to sexual health services is critical in light of rising sexually transmitted infections (STIs). We evaluated a hub-and-spoke model for improving access to sexual health services in three general practices in Victoria, Australia. The primary outcome was the impact on HIV and STI (chlamydia, gonorrhoea, syphilis) testing. Segmented linear regression analysis was conducted to examine the trends in the total HIV/STI tests pre- (from…
Point-of-Care Diagnostics for Diagnosis of Active Syphilis Infection
Syphilis, a curable sexually transmitted infection, has re-emerged as a global public health threat with an estimated 5.6 million new cases every year. Pregnant women and men who have sex with men are key target populations for syphilis control and prevention programs. Frequent syphilis testing for timely and accurate diagnosis of active infections for appropriate clinical management is a key strategy to effectively prevent disease transmission. …
Exploring the Use of “Nudges” to Improve HIV and Other Sexually Transmitted Infection Testing Among Men Who Have Sex with Men
Behavioral economics and its applied branch “nudging” can improve individual choices in various health care settings. However, there is a paucity of research using nudges to improve regular testing for HIV and other sexually transmitted infections (STIs). The study examined which reminder system and message type men who have sex with men (MSM) preferred to remind them to undergo regular 3-monthly HIV and STI testing. A cross-sectional survey stud…
