Crowdsourced partner services among men who have sex with men living with HIV: A pilot randomized controlled trial in China.

BACKGROUND: This study aimed to assess the acceptability, feasibility, and preliminary effectiveness of a crowdsourced HIV partner services (PS) intervention among men who have sex with men living with HIV (MLWH) in China. METHODS: A pilot two-arm randomized controlled trial (RCT) was conducted in three HIV testing clinics in China. The control arm received conventional HIV PS while the intervention arm received a crowdsourced intervention, including HIV self-testing kits for secondary distribution (HIVST-SD), digital education materials, and assisted PS. The intervention was developed through two-phase crowdsourcing events including an open call and a Designathon. The primary outcomes were measured by the 3-month follow-up rate (i.e., the proportion of participants who completed the follow-up survey to report HIV PS outcomes three months after enrollment) and the frequency of using intervention components (feasibility), index evaluation of intervention components (acceptability), and the proportion of partners getting HIV testing (preliminary effectiveness). RESULTS: The study enrolled 121 newly diagnosed MLWH between July 2021 and May 2022. The 3-month follow-up rates were 93% (75/81) and 83% (33/40) in the intervention and control arms, respectively. Crowdsourced intervention components demonstrated feasibility, with all indexes utilizing digital educational materials, 23 successfully using HIVST-SD, and six employing provider-referral to notify nine sexual partners. Acceptability was high, with HIVST-SD and digital educational materials rated 4·4 and 4.1 out of 5. The proportion of partners receiving HIV testing was 11% higher in the intervention arm than in the control arm (marginal significance with 95% CI = [-2%, 24%], 38% vs. 27%). CONCLUSION: The crowdsourced HIV PS intervention was acceptable and feasible, suggesting the potential to facilitate partner HIV testing among Chinese MLWH. Further implementation research is recommended to expand HIV PS among key populations in low- and middle-income countries.Clinical trial registration ID: NCT04971967 (Protocol ID: 19-0496).

Intimate partner violence and its correlates in middle-aged and older adults during the COVID-19 pandemic: A multi-country secondary analysis.

Intimate partner violence (IPV) may have been exacerbated during the COVID-19 pandemic. Middle-aged and older adults, ages 45 years or older, are at higher risk of COVID-19 mortality and social isolation. However, most studies on IPV during the pandemic do not focus on this important subpopulation. Informed by the social-ecological theory, this study examines individual, household, community, and country-level correlates of IPV among middle-aged and older adults in multiple countries using a cross-sectional online survey. Data from 2867 participants aged 45 or older in the International Sexual Health and Reproductive Health (I-SHARE) survey from July 2020 to February 2021 were described using univariate analysis. IPV was defined using four validated WHO measures. Individual characteristics included self-isolation and food security. At the country-level, we examined social distancing stringency. Logistic regression models with a random intercept for country were conducted to explore IPV correlates among 1730 eligible individuals from 20 countries with complete data. Most participants were heterosexual (2469/2867), cisgender (2531/2867) females (1589/2867) between the ages of 45-54 (1539/2867). 12.1% (346/2867) of participants experienced IPV during social distancing measures. After adjustment, participants who self-isolated experienced 1.4 (95% CI 1.0, 2.0, p = 0.04) times the odds of IPV compared to those who had not isolated. Those who reported an increase in food insecurity compared to pre-pandemic experienced 2.2 times the odds (95% CI 1.6, 3.0, p<0.0001) of IPV compared to those who did not report increased food insecurity. People in countries with more stringent social distancing policies were less likely to experience IPV compared to people in countries with lower levels of stringency (aOR = 0.6, 95% CI 0.4, 0.9, p = 0.04). IPV was common among middle-aged and older adults during the COVID-19 pandemic. Our data suggest the need for further crisis management and social protection measures for middle-aged and older adults who have intersecting vulnerabilities to IPV to mitigate COVID-19 impact.

A Machine Learning Model for Identifying Sexual Health Influencers to Promote the Secondary Distribution of HIV Self-Testing Among Gay, Bisexual, and Other Men Who Have Sex With Men in China: Quasi-Experimental Study.

BACKGROUND: Sexual health influencers (SHIs) are individuals actively sharing sexual health information with their peers, and they play an important role in promoting HIV care services, including the secondary distribution of HIV self-testing (SD-HIVST). Previous studies used a 6-item empirical leadership scale to identify SHIs. However, this approach may be biased as it does not consider individuals' social networks. OBJECTIVE: This study used a quasi-experimental study design to evaluate how well a newly developed machine learning (ML) model identifies SHIs in promoting SD-HIVST compared to SHIs identified by a scale whose validity had been tested before. METHODS: We recruited participants from BlueD, the largest social networking app for gay men in China. Based on their responses to the baseline survey, the ML model and scale were used to identify SHIs, respectively. This study consisted of 2 rounds, differing in the upper limit of the number of HIVST kits and peer-referral links that SHIs could order and distribute (first round ≤5 and second round ≤10). Consented SHIs could order multiple HIV self-testing (HIVST) kits and generate personalized peer-referral links through a web-based platform managed by a partnered gay-friendly community-based organization. SHIs were encouraged to share additional kits and peer-referral links with their social contacts (defined as "alters"). SHIs would receive US $3 incentives when their corresponding alters uploaded valid photographic testing results to the same platform. Our primary outcomes included (1) the number of alters who conducted HIVST in each group and (2) the number of newly tested alters who conducted HIVST in each. We used negative binomial regression to examine group differences during the first round (February-June 2021), the second round (June-November 2021), and the combined first and second rounds, respectively. RESULTS: In January 2021, a total of 1828 men who have sex with men (MSM) completed the survey. Overall, 393 SHIs (scale=195 and ML model=198) agreed to participate in SD-HIVST. Among them, 229 SHIs (scale=116 and ML model=113) ordered HIVST on the web. Compared with the scale group, SHIs in the ML model group motivated more alters to conduct HIVST (mean difference [MD] 0.88, 95% CI 0.02-2.22; adjusted incidence risk ratio [aIRR] 1.77, 95% CI 1.07-2.95) when we combined the first and second rounds. Although the mean number of newly tested alters was slightly higher in the ML model group than in the scale group, the group difference was insignificant (MD 0.35, 95% CI -0.17 to -0.99; aIRR 1.49, 95% CI 0.74-3.02). CONCLUSIONS: Among Chinese MSM, SHIs identified by the ML model can motivate more individuals to conduct HIVST than those identified by the scale. Future research can focus on how to adapt the ML model to encourage newly tested individuals to conduct HIVST.

Crowdsourcing to increase hepatitis B and C testing and reduce hepatitis stigma among medical students in Bangladesh.

This study addresses the pervasive challenges of low hepatitis B (HBV) and hepatitis C (HCV) testing rates coupled with the stigma associated with these diseases in low- and middle-income countries (LMICs) with a special focus on Bangladesh. This study aims to introduce an innovative crowdsourcing intervention that involves medical students, a crucial cohort with the potential to shape healthcare attitudes. Through a structured crowdsourcing approach, the study designs and implements a digital intervention to counter stigma and promote testing among medical students in Dhaka, Bangladesh. Participants submitted brief videos or texts aiming to encourage hepatitis testing and reduce stigma. The call, advertised through meetings, emails, and social media, welcomed entries in English or Bengali over 3 weeks. A panel of six judges evaluated each entry based on clarity, impact potential, innovation, feasibility, and sustainability, awarding prizes to students behind the highest-rated submissions. Seventeen videos and four text messages received an average score of 5.5 among 440 surveyed medical students, predominantly 22 years old (16%) and in their fourth year (21%). After viewing, 360 students underwent screening, identifying two previously undiagnosed HBV cases referred for care; no HCV infections were found. Notably, 41% expressed concerns about individuals with HBV working in hospitals or having a doctor living with HBV. In conclusion, this pilot showcases the power of medical students in spearheading campaigns to counter hepatitis stigma and encourage testing. By utilizing crowdsourcing, the study introduces an innovative approach to a persistent issue in LMICs specially in Bangladesh, offering a model that could potentially be adapted by other regions grappling with similar challenges.

Sexual attitudes and utilization of sexual and reproductive health services among older women in southern China: a qualitative study.

Objective: Sexual health plays a vital role in healthy aging. However, little is known about the sexual attitudes of and the utilization of sexual and reproductive health services by older women in China. This article is based on a qualitative study of older Chinese women in suburban areas to examine their attitudes toward sexuality and their utilization of sexual and reproductive health services. Methods: Face-to-face semi-structured interviews were conducted with older women (ages 50 to 74) from suburbs of southern China. Participants were purposively sampled on a convenience basis and recruited when they were visiting community health facilities between June and December 2021. Inclusion criteria were older women aged 50 years and older who had sexual experience. A topic guide was used that focused on sexual activity, sexual attitudes, the utilization of sexual and reproductive health services, and the factors that influence these. Interviews were audio recorded and transcribed verbatim. We coded the data inductively and conducted a thematic analysis. Results: Twenty-six Chinese women participated in the study. These older women had varying attitudes regarding sexual activity and its significance for older adults. The gender norms they held concerning sexual desire deemed that men had higher sexual desire than women. Most asymptomatic women did not actively seek sexual and reproductive health services. In most cases, women only sought professional services when they started to have sexual and reproductive health problems. Factors influencing the uptake of sexual and reproductive health services by older women were cost (affordability), availability, distance (accessibility), and conservative cultural norms towards sexuality. Conclusion: The attitudes of older women towards sexual activity are diverse. While some view sexual activity as common and essential for maintaining a sense of well-being in older age, others may hold different perspectives, considering it less significant. The utilization of sexual and reproductive health services by older Chinese women, except for when they were having a specific health issue, was low. Sexual health messages and services tailored for older women are needed.

A behavioral economics approach to enhancing HIV preexposure and postexposure prophylaxis implementation.

PURPOSE OF REVIEW: The 'PrEP cliff' phenomenon poses a critical challenge in global HIV PrEP implementation, marked by significant dropouts across the entire PrEP care continuum. This article reviews new strategies to address 'PrEP cliff'. RECENT FINDINGS: Canadian clinicians have developed a service delivery model that offers presumptive PEP to patients in need and transits eligible PEP users to PrEP. Early findings are promising. This service model not only establishes a safety net for those who were not protected by PrEP, but it also leverages the immediate salience and perceived benefits of PEP as a natural nudge towards PrEP use. Aligning with Behavioral Economics, specifically the Salience Theory, this strategy holds potential in tackling PrEP implementation challenges. SUMMARY: A natural pathway between PEP and PrEP has been widely observed. The Canadian service model exemplifies an innovative strategy that leverages this organic pathway and enhances the utility of both PEP and PrEP services. We offer theoretical insights into the reasons behind these PEP-PrEP transitions and evolve the Canadian model into a cohesive framework for implementation.

A Conference Designathon to Spark Innovation: Actionable Ideas to Enhance STD Control.

BACKGROUND: Designathons can be used to enhance public health training and spur innovation. A designathon is a three-stage participatory activity that includes preparation, intensive collaboration, and follow-up activities. We organized a designathon focused on developing actionable sexually transmitted disease (STD) control strategies and examined the content of ideas resulting from an STD designathon. METHODS: For this designathon we created four groups: early career researchers, silver group (people with >10 years of experience), travelers (people from low- and middle-income countries and those who received a conference scholarship) and a community group. Each group developed its own plan to consult members, iteratively develop ideas, and aggregate insights. Each group developed STD control strategies that were presented. Cross-cutting themes across these ideas were identified. RESULTS: Designathon participants included a subset of conference participants. Cross-cutting themes from final ideas included co-creating STD interventions with end-users, using sex-positive framing, enhancing open access digital STD resources, and reducing STD stigma. Early career researchers presented a call for community ideas focusing on ending STD epidemics by increasing accessibility to STD care services among all populations. The silver group proposed digital innovations, including an AI-powered tool for testing and treatment and a social game to promote sex positivity. The traveler group conceptualized an information hub to support implementation of STD programs. Community members underscored the importance of a more human-centered approach to STD control which reduces stigma and normalizes sex and sexual pleasure. CONCLUSION: Sex positive campaigns and open access digital resources should be considered within STD programs. Implementation research studies are needed to evaluate these ideas.

Correlates of sexual and reproductive health service utilization among older adults in China: Findings from the sexual well-being (SWELL) study.

BACKGROUND: Sexual and reproductive health (SRH) is critical to the overall health of older adults. We assessed the utilization of SRH services and its correlates among older adults in China. METHODS: We recruited community-dwelling adults aged 50 and above in five Chinese cities between June 2020 and December 2022. In this study SRH services included reproductive health examination, cervical cancer screening, and sexual life counselling. Logistic regression was used to assess correlates of SRH services utilization. RESULTS: A total of 3001 older adults (1819 men and 1182 women) were enrolled. Among them, 11.4 % (343/3001) of participants received a reproductive health examination, 35.4 % (418/1182) of female participants received cervical cancer screening, and 30.1 % (401/1332) of sexually active participants sought help for their sexual lives. Older men with an annual income of USD 7500 or more (aOR = 3.21, 95%CI: 1.39-7.44), two or more chronic conditions (2.38, 1.39-4.08), and reproductive health problems (2.01, 1.18-3.43) were more likely to receive a urological examination. For older women, individuals who were younger (aged 50-59 years: 5.18, 2.84-9.43; aged 60-69 years: 2.67, 1.49-4.79), lived in an urban area (1.88, 1.31-2.71), were employed (1.73, 1.21-2.47), had two or more chronic conditions (2.04, 1.37-3.05), were sexually active (1.72, 1.15-2.58) and talked about sex (1.69, 1.21-2.36) were more likely to receive a gynecological examination. CONCLUSION: SRH services utilization among older adults was low, with urological examination among older men particularly low. SRH messages and services tailored for older adults are needed to enhance their utilization of SRH services.

HIV Services Uptake Among People Living with HIV in Jiangsu Province, China: A Cross-Sectional Study.

Healthcare disparities are common among people living with HIV (PLWH) in China and likely impact access to HIV services. This study aimed to assess the current status of access to HIV services among PLWH and explore the correlates of service uptake using baseline data from a prospective cohort study among PLWH in Jiangsu Province. Guided by Andersen's behavioral model, univariable and multivariable logistic regressions were conducted to identify factors associated with access to HIV services. Out of 8989 eligible PLWH included in this study, 46.4% perceived difficulty in seeing a healthcare professional for HIV treatment services in 2021-2022. PLWH aged 18-34 years (adjusted odds ratio [AOR] = 1.69, 95% CI 1.32-2.15), 35-39 years (AOR = 1.33, 95% CI 1.08-1.65), identified as a bisexual/other (AOR = 1.14, 95% CI 1.01-1.29), had a college and above education (AOR = 1.32, 95% CI 1.07-1.63), and perceived moderate (AOR = 1.70, 95% CI 1.51-1.91) and severe (AOR = 2.20, 95% CI 1.94-2.49) levels of HIV stigma were more likely to perceive difficulty in seeing healthcare professionals for HIV treatment in 2021-2022. Living in northern Jiangsu was also associated with increased odds of perceiving difficulty in seeing healthcare professionals for HIV treatment (AOR = 1.12, 95% CI 1.00-1.26). These findings underscore the need for innovative solutions to eliminate the practical barriers to HIV services utilization among PLWH who are bisexual, well-educated, and effective HIV-related stigma reduction interventions.

Social innovation in health training to engage researchers in resource-limited settings: process description and evaluation.

Research on social innovations in health has increased in recent years. However, little training is geared toward enhancing social innovation research capacity. Most health training for low- and middle-income countries (LMICs) is developed by individuals in high-income countries, disregarding LMIC researchers' wisdom and insights and the communities' needs. Our team organized a multi-phase investigation involving a series of surveys and co-creation group discussions to assess individuals' training needs that directly informed a subsequent co-created training workshop series. We conducted a Hennessy-Hicks Training Needs Assessment among the Social Innovation in Health Initiative (SIHI) network and formed a co-creation group comprising SIHI fellows to design related training workshops. We ran a final evaluation survey and analyzed the workshop series' strengths, weaknesses and threats. Descriptive and thematic analysis were employed to analyze survey data and open-ended responses. The final evaluation survey captured data from 165 learners in 35 countries, including 26 LMICs. Most participants (67.3%, 111/165) rated the training workshop series as excellent, and 30.3% (50/165) rated it as good on a five-point scale. The need for writing research grants and manuscripts was rated the highest priority. Learners were interested in community-engaged research and diversity, equity and inclusion. This workshop illustrated how co-creation could be an effective tool for developing training materials tailored for LMIC researchers. We also offer a template for conducting a needs assessment and subsequent training workshops for LMICs. The ground-up, locally developed courses may be more effective than externally developed training programs intended for LMICs.

Designathons in health research: a global systematic review.

INTRODUCTION: A designathon is a three-stage participatory activity informed by design thinking. There is a growing literature on designathons in health. This study synthesised designathons' effectiveness and implementation-related factors to address health challenges. METHODS: We searched Cochrane Library, Embase, PubMed, Scopus and the ClinicalTrials.gov registry for articles containing primary data on designathons for health from their dates of inception to 29 November 2022. We retrieved additional studies from citation searching and a complementary open call. We synthesised data on designathons' effectiveness (ie, engagement, outputs and implementation), required resources and implementation-related factors (ie, resources, facilitators, barriers, strengths and limitations). We assessed the risk of bias using a checklist adapted from Joanna Briggs Institute Critical Appraisal tools. RESULTS: In total, 4973 citations were identified, and 42 studies were included. In total, 26 studies (62%) were from high-income countries. The median number of total participants was 49, divided into a median of 8 teams. The duration of the intensive collaboration phase ranged from 3 hours to 7 days. Common evaluation criteria were feasibility, innovation and impact. Idea and prototype outputs included mobile phone applications, educational programmes and medical devices. Interventions developed from a designathon was estimated to be highly cost-effective. The most common facilitators were interdisciplinary participants and high-quality mentorship. The most common barriers were suboptimal execution of the events, difficulties in balancing interdisciplinary participants across teams and limited support for participants along the process. There were limited data on required resources and further implementation of solutions after designathons. CONCLUSION: Given designathons' adaptability in terms of budget, mode of delivery, type of output and involvement of diverse participants, including end users, designathons can be implemented in a wide range of contexts to address various health issues.

Catching lightning in a bottle: the STI and HIV 2023 World Congress Participatory Designathon.

The International Society for STD Research (ISSTDR) STI/HIV 2023 World Congress convened a participatory designathon to engage attendees in a problem-solving crowdsourcing event with the mission to design innovative solutions for improving sexually transmitted infection (STI) control. Designathons are three-phase crowdsourcing events consisting of a pre-planning phase, an active and intensive collaborative phase, and denouement phase for implementation and dissemination. Given escalating STI concerns, the Congress organisers recognised the opportunity to harness the collective expertise of the attendees by actively engaging them to generate innovative solutions for STI control by hosting a designathon during the scientific meeting. Designathon activities occurred during the Congress, and innovative solutions were presented during the closing plenary. Organisers prioritised participant diversity and engagement by creating four distinct groups based on lived experiences (Silver, Early Career, Traveller, and Community). Although competing priorities through the Congress were a challenge, participation from the attendees was high. Dedicated time and space for the event allowed for a successful designathon event, and the lack of restrictions, as might be encountered from funders or other stakeholder agencies, allowed participants to creatively develop innovative solutions for STI control. This designathon serves as an exemplar for successfully hosting a designathon at a large scientific meeting to engage attendees and contribute their intellect and voice to collectively solving significant problems.

Ignored and undervalued in public health: a systematic review of health state utility values associated with syphilis infection.

BACKGROUND: Syphilis is a sexually transmitted infection causing significant global morbidity and mortality. To inform policymaking and economic evaluation studies for syphilis, we summarised utility and disability weights for health states associated with syphilis. METHODS: We conducted a systematic review, searching six databases for economic evaluations and primary valuation studies related to syphilis from January 2000 to February 2022. We extracted health state utility values or disability weights, including identification of how these were derived. The study was registered in the international prospective register of systematic reviews (PROSPERO, CRD42021230035). FINDINGS: Of 3401 studies screened, 22 economic evaluations, two primary studies providing condition-specific measures, and 13 burden of disease studies were included. Fifteen economic evaluations reported outcomes as disability-adjusted life years (DALYs) and seven reported quality-adjusted life years (QALYs). Fourteen of 15 economic evaluations that used DALYS based their values on the original Global Burden of Disease (GBD) study from 1990 (published in 1996). For the seven QALY-related economic evaluations, the methodology varied between studies, with some studies using assumptions and others creating utility weights or converting them from disability weights. INTERPRETATION: We found a limited evidence base for the valuation of health states for syphilis, a lack of transparency for the development of existing health state utility values, and inconsistencies in the application of these values to estimate DALYs and QALYs. Further research is required to expand the evidence base so that policymakers can access accurate and well-informed economic evaluations to allocate resources to address syphilis and implement syphilis programs that are cost-effective.

The HI V O pen Call on I nformed C onsent and E thics in Research (VOICE) for Adolescents and Young Adults: A Digital Crowdsourcing Open Call in Low- and Middle-Income Countries.

BACKGROUND: Many adolescents and young adults (AYAs; 10-24 years old) are excluded from HIV research because of social, ethical, and legal challenges with informed consent, resulting in limited AYA-focused data. We use a participatory approach to identify strategies for improving AYA consent processes in HIV research in low- and middle-income countries (LMICs). METHODS: We conducted a digital crowdsourcing open call for ideas to improve AYA consent to HIV research in LMICs. Crowdsourcing involves engaging a group of people in problem-solving, then sharing emergent solutions. Submissions were evaluated by 3 independent judges using predefined criteria, with exceptional strategies receiving prizes. Demographic data were collected, and textual data were qualitatively analyzed for emergent themes in barriers and facilitators for improving AYA consent in HIV research, guided by a socioecological model. RESULTS: We received 110 strategies total; 65 were eligible for evaluation, 25 of which were identified as finalists. Fifty-eight participants from 10 LMICs submitted the 65 eligible submissions, of which 30 (52%) were 18 to 24 years old. Thematic analysis identified 10 barriers to AYA consent, including HIV stigma, limited education, and legal/regulatory barriers. Strategies for improving AYA consent processes revealed 7 potential facilitators: enhancing AYA engagement in research, involving parents/guardians, improving education/awareness, improving institutional practices/policy, making research participation more AYA-friendly, enhancing engagement of other key communities of interest, and empowering AYA. CONCLUSIONS: Diverse communities of interest in LMICs developed compelling strategies to enhance informed consent that may improve AYA inclusion in HIV research. These data will be used to develop practical guidance on improving AYA consent processes.

A designathon to co-create HPV screening and vaccination approaches for mothers and daughters in Nigeria: findings from a community-led participatory event.

Background: Oncogenic types of human Papillomavirus (HPV) infection cause substantial morbidity and mortality in Nigeria. Nigeria has low cervical cancer screening and vaccination rates, suggesting the need for community engagement to enhance reach and uptake. We organised a designathon to identify community-led, innovative approaches to promote HPV screening and vaccination for women and girls, respectively, in Nigeria. A designathon is a three-phase participatory process informed by design thinking that includes the preparation phase that includes soliciting innovative ideas from end-users, an intensive collaborative event to co-create intervention components, and follow-up activities. Methods: We organised a three-phase designathon for women (30-65yrs) and girls (11-26yrs) in Nigeria. First, we launched a national crowdsourcing open call for ideas on community-driven strategies to support HPV screening among women and vaccination among girls. The open call was promoted widely on social media and at in-person gatherings. All eligible entries were graded by judges and 16 exceptional teams (with 4-6members each). All six geo-political zones of Nigeria were invited to join an in-person event held over three days in Lagos to refine their ideas and present them to a panel of expert judges. The ideas from teams were reviewed and scored based on relevance, feasibility, innovation, potential impact, and mother-daughter team dynamics. We present quantitative data on people who submitted and themes from the textual submissions. Results: We received a total of 612 submissions to the open call from mother-daughter dyads. Participants submitted ideas via a website designated for the contest (n=392), in-person (n=99), email (n=31), or via an instant messaging application (n=92). Overall, 470 were eligible for judging after initial screening. The average age of participants for daughters was 19 years and 39 years for mothers. Themes from the top 16 proposals included leveraging local leaders (5/16), faith-based networks (4/16), educational systems (4/16), and other community networks (7/16) to promote awareness of cervical cancer prevention services. After an in-person collaborative event, eight teams were selected to join an innovation training boot camp, for capacity building to implement ideas. Conclusions: Innovative strategies are needed to promote HPV screening for mothers and vaccination for girls in Nigeria. Our designathon was able to facilitate Nigerian mother-daughter teams to develop cervical cancer prevention strategies. Implementation research is needed to assess the effectiveness of these strategies.

Sexual function and correlates among adults aged 50+ years in China: Findings from the sexual well-being (SWELL) study.

BACKGROUND: Sexual function is an important yet understudied aspect of overall health and well-being in older adults. We aimed to examine sexual function and its correlates among people 50 years and older in China. METHODS: We enrolled people aged 50 years and older recruited from four regions in China between September 2021 and July 2022 in a multicenter cross-sectional study. Data were collected through an investigator-administered questionnaire about demographic characteristics, health characteristics, and sexual function status. Logistic regression was used to assess correlates of lower sexual function (the highest quintile of the sex-specific population distribution of Natsal-SF scores [i.e., lower functioning compared with the remaining]). RESULTS: A total of 465 women and 832 men who were sexually active in the past year were included in the analysis (mean age: 60.4 ± 7.2) [Correction added after first online publication on 12 Feb 2024. The word "years" has been changed to "year" in this sentence.]. Over a quarter of all participants were dissatisfied with their sex life. Notably, 92 women and 167 men were categorized as having a lower sexual function. Age (in men only), living in urban areas, general health status, being underweight or overweight (in men only), and having depressive symptoms were associated with lower sexual function. Among all participants, 43.1% of men and 54.0% of women experienced sexual response problems lasting 3 months or more. Less than one-third of all participants had sought help or advice for sex life in the past year. CONCLUSIONS: Sexual dysfunction and sexual dissatisfaction are prevalent among older adults in China and are associated with self-assessed poor health. More efforts are needed to better understand sexual health needs and tailor service provision.

Homoprejudiced Violence Experiences and High-Risk Sexual Behaviors among Chinese Men Who Have Sex with Men: Depression Severity and Recreational Drug Usage as Potential Mediators.

Homoprejudiced violence is a type of aggression against an individual or a community based on their actual or perceived sexual orientation. It may be linked to risks of acquiring HIV/STI via psychosocial variables. This study explored the association between homoprejudiced violence experiences and high-risk sexual behaviors, and potential psychosocial mediators. Using cross-sectional survey data collected in China through Blued among men who have sex with men (MSM) in January 2021, this study conducted multiple mediation analyses. Standard instruments were used to collect data on depressive symptoms in the last two weeks (PHQ-9), recreational drug usage in the last three months, and ever experiencing homoprejudiced violence (12-item survey instrument). Dependent variables were having condomless anal sex and having three or more sexual partners in the last three months. Among 1828 MSM, nearly half (847, 46%) had experienced homoprejudiced violence. Twenty-three percent (427) reached a score that suggested moderate or severe depression and 35% (644) had used recreational drugs. In the last three months, 40% (731) had condomless anal sex and 34% (626) had three or more sexual partners. The indirect mediational coefficients through depression on condomless anal sex and multiple sexual partners were 0.04 (95% CI: [0.02, 0.07]) and 0.02 (95% CI: [0.001, 0.05]), respectively. The indirect mediational coefficient of homoprejudiced violence experience on multiple sexual partners through recreational drug use was 0.05 (95% CI: [0.03, 0.08]). These findings suggest that more comprehensive interventions are needed to address the syndemic of homoprejudiced violence, mental health issues, and HIV/STI-related risks.

Factors Associated with the First-time HIV Testing Among Chinese men who have sex with men Who Received HIV Self-tests from Partners or Friends.

Secondary distribution of HIV self-testing (HIVST) among individual social networks was an effective approach to expanding HIV testing among men who have sex with men (MSM). However, understanding the factors associated with first-time HIV testing behaviors in the secondary distribution of HIVST programs is limited. Hence, this study aims to identify factors related to first-time testers in the secondary distribution of HIVST. Participants were recruited from five provinces in southern China through Blued, a geo-social gay networking app in China from January 2021 to December 2021. Eligible consented participants (referred to as "seeds") finished a baseline survey and then applied for up to five HIVST kits. They were encouraged to distribute HIVST kits to other MSM (referred to as "alters") and alters were encouraged to scan a QR code to return their photographed testing results. All alters were invited to finish an online survey. In total, 229 seeds reached 292 alters, among whom 126 (43.2%) were first-time testers whereas 166 (56.8%) were non-first-time testers. Importantly, our results demonstrated that the first-time HIV testers were more likely to self-report as heterosexual (aOR = 4.88, 95% CI 1.01-23.61), disclose sexual orientation and/or SSB (aOR = 1.73, 95% CI 1.01-2.96), and receive HIVST knowledge from the seeds (aOR = 3.25, 95% CI 1.02-10.34). However, those who had sex with male partners in the last three months were less likely to be first-time testers (aOR = 0.43, 95% CI 0.23-0.82). Practical implications and limitations were also discussed to improve future HIV prevention programs.

Acute facial neuralgia related to initiation of emtricitabine/tenofovir for HIV PrEP: a report of two cases in a PrEP demonstration trial.

BACKGROUND: Emtricitabine (FTC) and tenofovir disoproxil fumarate (TDF) fixed-dose combination (FTC/TDF) is generally well-tolerated, although treatment-related adverse events have been reported. METHODS: We report two cases of persons using FTC/TDF PrEP who had acute neuralgia in a Chinese PrEP demonstration trial. RESULTS: Neurological symptoms subsided upon treatment discontinuation. Symptoms were reported as similar to one case's previous experiences with dolutegravir (DTG)+FTC+tenofovir alafenamide (TAF) (for PEP), leading to permanent discontinuation of PrEP. CONCLUSION: Acute facial neuralgia appears to be a rare idiosyncratic adverse event to FTC/TDF.
