RESUMO

Artificial Intelligence (AI) applications have shown promise in the management of pandemics. In response to the global Monkeypox (Mpox) outbreak, the HeHealth.ai team leveraged an existing tool to screen for sexually transmitted diseases (STD) to develop a digital screening test for symptomatic Mpox using AI. Before the global Mpox outbreak, the team developed a smartphone app (HeHealth) where app users can use a smartphone to photograph their own penises to screen for symptomatic STD. The AI model initially used 5000 cases and a modified convolutional neural network to output prediction scores across visually diagnosable penis pathologies including syphilis, herpes simplex virus, and human papillomavirus. A total of about 22,000 users had downloaded the HeHealth app, and ~21,000 images were analysed using HeHealth AI technology. We then used formative research, stakeholder engagement, rapid consolidation images, a validation study, and implementation of the tool. A total of 1000 Mpox-related images had been used to train the Mpox symptom checker tool. Based on an internal validation, our digital symptom checker tool showed specificity of 87% and sensitivity of 90% for symptomatic Mpox. Several hurdles identified included issues of data privacy and security for app users, initial lack of data to train the AI tool, and the potential generalisability of input data. We offer several suggestions to help others get started on similar projects in emergency situations, including engaging a wide range of stakeholders, having a multidisciplinary team, prioritising pragmatism, as well as the concept that 'big data' in fact is made up of 'small data'.

RESUMO

OBJECTIVES: Monkeypox (mpox) was declared as a global health emergency by the WHO, with most reported cases disproportionately involving gay, bisexual and other men who have sex with men (GBMSM). This study explored the willingness of Singaporean GBMSM to receive mpox vaccines and engage in changes to sexual behaviour, and analysed the factors influencing both decisions. METHODS: An online cross-sectional study was disseminated through community groups and Grindr from September to October 2022 among GBMSM in Singapore, where we surveyed respondents' demographics, stigma associated with mpox, perceived risks of sexually transmitted infections (STIs) and changes to sexual behaviours in response to mpox. Descriptive statistics and multivariable linear and logistics regression analyses, as well as thematic analysis of data, were also conducted. RESULTS: 237 GBMSM community members responded to the survey, with the majority being receptive to vaccine and 67.5% indicating changes to sexual behaviour in view of rising mpox infections. Predictors of vaccine receptivity among GBMSM included self-perceived mpox risk (adjusted OR (aOR)=0.44, 95% CI 0.07, 0.82) and self-perceived STI risk (aOR=0.39, 95% CI 0.03, 0.76). Predictors for changes to sexual behaviour included self-perceived mpox stigma (aOR=1.17, 95% CI 1.08, 1.27), self-perceived mpox risk (aOR=1.22, 95% CI 1.03,1.44), age (aOR=0.96, 95% CI 0.93, 1.00) and race (aOR=0.31, 95% CI 0.10, 0.93). In the thematic analysis, respondents raised concerns about vaccine effectiveness, side effects, cost and privacy. CONCLUSIONS: Our findings suggest that the rise in mpox infections have prompted changes to GBMSM's sexual practices. In general, GBMSM are willing to receive the mpox vaccine but are concerned about the physical and social consequences of uptake. These concerns should be addressed when vaccines are released.

RESUMO

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.

RESUMO

BACKGROUND: In Singapore, where drug use is a highly stigmatized and criminalized issue, there is limited understanding of the challenges faced by individuals, particularly sexual minority men, in their journey towards recovery from substance dependence or addiction. This qualitative study aimed to investigate the driving forces behind drug use, the factors contributing to drug cessation, and the elements influencing the recovery process. METHODS: Data were extracted from clinical records provided by  The Greenhouse Community Services Limited between January 2020 to May 2022. These records encompassed information from four distinct forms: the intake assessment, progress notes, case closing summary, and the care plan review. Thematic analysis was employed to identify and categorize recurring themes within the data. RESULTS: Data from beneficiaries (n = 125) were analyzed and yielded a series of themes related to facilitators of drug use, motivations to cease drug use, and managing one's ongoing recovery. Within the facilitators of drug use, two sub-themes were identified: (a) addressing trauma and triggers and (b) managing emotions. Additionally, managing one's recovery was marked by four significant sub-themes: (a) uncovering personal identities, (b) losing motivation and drive, (c) overcoming obstacles, and (d) preparing for aftercare. CONCLUSIONS: The study contributes valuable insights into the dynamics of ongoing recovery management, offering potential avenues for interventions that could enhance support for individuals in their journey to overcome substance dependence. Enhancing psychoeducation and fostering peer support have the potential to facilitate the recovery process. Clearly, a holistic approach is needed to address these complex issues that cuts across our societies.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Chinese gay, bisexual, and other men who have sex with men (GBMSM) face discrimination in many facility-based health services, thus increasing the importance of online engagement. The purpose of this study was to examine online GBMSM community spaces and implications for HIV/sexually transmitted disease prevention services. METHODS: We conducted a total of 6 online focus group discussions with Chinese GBMSM from Guangdong province on the chat-based platform WeChat in 2021. Focus group discussions were asynchronous, and participants were able to provide and map out online spaces that they had participated in and share their perspectives on online engagement. Data were analyzed through framework analysis. RESULTS: Overall, 48 participants participated. Most were mainly sexually attracted to men (n = 43; 90.0%) and never participated in in-person LGBTQ-related events (n = 29; 60.4%). Participants articulated a typology of online spaces along the axes of whether such spaces were Chinese platforms (vs. non-Chinese) or whether they were GBMSM-specific (vs. non-GBMSM-specific). Participants articulated several advantages of online spaces, including greater anonymity, opportunities for community building, sharing of sexual health information, and being able to meet other GBMSM more efficiently. Drawbacks included the lack of personal connection, lack of safety measures for youth, encountering deception and the use of fake profile pictures, and needing a virtual proxy network to access some websites. Participants provided suggestions to further improve their experiences of online spaces. CONCLUSIONS: Although broad-based, GBMSM-specific messaging can be implemented in Chinese, GBMSM-specific spaces, sexual health messaging may also reach niche GBMSM communities in a variety of non-GBMSM spaces.

RESUMO

Importance: Prosocial interventions encourage voluntary actions that benefit others. Community solidarity in response to the COVID-19 pandemic, expanding mutual aid programs, and health workforce issues have accelerated prosocial health interventions. Objective: To investigate the association of prosocial interventions with health outcomes in clinical trials and observational studies. Data Sources: In this systematic review and meta-analysis informed by the Cochrane Handbook for Systematic Reviews of Interventions, 5 databases (MEDLINE [via PubMed], Embase, CINAHL, PsycInfo, and Scopus) were searched from database inception through February 23, 2023. The search included terms for altruism and prosocial behaviors, health outcomes, and study type. Study Selection: Included studies, determined by multiple reviewers, compared health outcomes in a prosocial intervention group with a nonintervention group. Data Extraction and Synthesis: Following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline, data extraction and synthesis captured quantitative and qualitative data. To pool data from quantitative studies, random-effects meta-analyses were used to estimate the impact of prosocial interventions. To combine data from quantitative and qualitive studies, data were transformed into qualitative narratives using meta-aggregation. Main Outcomes and Measures: The main outcome was whether prosocial interventions were associated with improved health outcomes. Barriers to and facilitators of implementation of these interventions were assessed. Results: The search identified 5229 citations; 30 studies were included in the synthesis. Studies indicated that prosocial interventions were associated with positive health outcomes for givers (17 studies [56.7]) and recipients (8 [26.7%]). Prosocial interventions included acts of kindness (12 studies [40.0%]), cash gifts (7 [23.3%]), pay-it-forward approaches (6 [20.0%]), and expressions of kindness (5 [16.7%]). Improvements were reported in depression, testing for sexually transmitted diseases, vaccine uptake, physical activity, and individual biomarkers. Data from 6 studies (20.0%) demonstrated that pay-it-forward approaches were associated with increased uptake of diagnostic tests or vaccines among vulnerable groups (moderate certainty of evidence). Data from 14 studies (46.7%) suggested that community connectedness facilitated prosocial interventions. Shared vulnerabilities among groups (eg, sexual minority individuals, older adults) may provide a context for collective mobilization to improve health in local communities. Conclusions and Relevance: This systematic review and meta-analysis found that prosocial interventions were associated with improved health outcomes among vulnerable groups and have been useful for addressing health disparities. Further research is needed to develop and evaluate prosocial interventions.

RESUMO

BACKGROUND: Gonorrhea and chlamydia are the most common sexually transmitted diseases (STDs) among men who have sex with men (MSM) in China. Previous studies have shown pay-it-forward (PIF) interventions to be associated with a substantial increase in gonorrhea and chlamydia test uptake compared to standard-of-care. We propose a 'pay-it-forward' gonorrhea and chlamydia testing randomized controlled trial (PIONEER). The trial would evaluate the effectiveness of two pay-it-forward strategies in promoting testing uptake compared to the standard of care (in which men pay for their tests out-of-pocket) among MSM and male STD patients in China. METHODS: PIONEER will be a three-armed, pragmatic cluster randomized controlled trial (RCT), conducted across 12 clinics (six MSM-led and six public STD clinics) to compare the effectiveness of three implementation strategies. Each facility will be randomized to a standard pay-it-forward intervention of gonorrhea/ chlamydia testing with minimal encouragement for testing, a community-engaged pay-it-forward arm, or a control arm where men pay for their tests out-of-pockets. The primary outcome will be dual gonorrhea/chlamydia test uptake. Secondary outcomes will include syphilis testing, amount donated in pay-it-forward, number of positive gonorrhea and chlamydia tests, and measures of antimicrobial resistance. A sequential transformative mixed methods design will be used to evaluate the implementation process in type 2 effectiveness-implementation hybrid design. Data sources will include survey on acceptability, and feelings and attitudes towards the interventions among participants; testing and treatment uptake data from clinic records, WeChat records, and qualitative data to gain insights into men's perceptions and attitudes towards the pay-it-forward, mechanisms driving uptake, and donating behaviors. Implementers and organizers will be interviewed about fidelity and adherence to protocol, sustainability of pay-it-forward intervention, and barriers and facilitators of implementing the intervention. DISCUSSION: PIONEER will substantially increase gonorrhea/chlamydia testing among MSM in China, providing an innovative and new financial mechanism to sustain STD screening among sexual minorities in low- and middle-income countries. This study will answer compelling scientific questions about how best to implement pay-it-forward and the individual and organizational characteristics that moderate it. TRIAL REGISTRATION: The study with identification number NCT05723263 has been registered on clinicaltrials.gov/.

RESUMO

Syndemics of poor mental health also drive poorer sexual health outcomes. This study used three scales, the Alcohol Use Disorders Identification Test (AUDIT), the Drug Abuse Screening Test (DAST-10), and the Depression Anxiety Stress Scale (DASS-21) among beneficiaries of sexual health services in Singapore (n =975), respectively. We found that a prevalence of 20.4% and 18.6% of hazardous and moderate-severe alcohol use disorders and substance use risks, respectively. About 13.7%, 18.1% and 10.5% of participants reported severe to extremely severe symptoms of depression, anxiety, and stress, respectively. Further investigation and integrated interventions for mental health in sexual health settings are warranted.

RESUMO

INTRODUCTION: Singapore lacks robust data on the sizes of the key populations that are most at risk for HIV. Using the network scale-up method for hidden or hard-to-reach populations, we estimate the sizes of five key populations-male clients of female sex workers (MCFSW), men who have sex with men (MSM), female sex workers (FSW), people who inject drugs (PWID) and transgender people-and profile the ages and ethnicities of respondents with the high-risk contacts they report knowing. METHODS: We conducted a cross-sectional online survey between March and May 2019 (n = 2802) using a network scale-up instrument previously developed for Singapore. Participants were recruited using an existing panel and online advertising, and the sample reweighted by age, sex, ethnicity and education attained to represent the general adult population. We built a Bayesian hierarchical model to estimate the sizes of the five key populations for HIV in Singapore. RESULTS: After adjustment, the sizes of the at-risk populations are estimated to be: 76,800 (95% credible interval [CI]: 64,200-91,800) MCFSW; 139,000 (95% CI: 120,000-160,000) MSM; 8030 (95% CI: 3980-16,200) FSW; 3470 (95% CI: 1540-7830) PWID and 18,000 (95% CI: 14,000-23,200) transgender people. Generally, men reported knowing more people in all the high-risk groups; older people reported knowing more MCFSW, FSW and transgender people; and younger people reported knowing more MSM. There was a bimodal effect of age on those who reported knowing more PWIDs: people in their 20s and 60s reported more contacts. CONCLUSIONS: This study demonstrates that a size estimation study of hidden populations is quickly and efficiently scalable through using online surveys in a socially conservative society, like Singapore, where key populations are stigmatized or criminalized. The approach may be suitable in other countries where stigma is prevalent and where barriers to surveillance and data collection are numerous.

RESUMO

Globally, gender-neutral Human Papillomavirus (HPV) vaccination programmes are gaining traction. Although cervical cancer remains the most prevalent, other HPV-related cancers are increasingly recognised as important, especially among men who have sex with men. We assessed if including adolescent boys in Singapore's school-based HPV vaccination programme is cost-effective from the healthcare perspective. We adapted a World Health Organization-supported model, Papillomavirus Rapid Interface for Modelling and Economics, and modelled the cost and quality-adjusted life years (QALY) associated with vaccinating 13-year-olds with the HPV vaccine. Cancer incidence and mortality rates were obtained from local sources and adjusted based on the expected direct and indirect vaccine protection for various population subgroups at an 80 % vaccine coverage. Moving to a gender-neutral vaccination programme with a bivalent or nonavalent vaccine could avert 30 (95 % uncertainty interval [UI]: 20-44) and 34 (95 % UI: 24-49) HPV-related cancers per birth cohort, respectively. At a 3 % discount rate, a gender-neutral vaccination programme is not cost-effective. However, with a 1.5 % discount rate, which puts more value on long-term health gains from vaccination, moving to a gender-neutral vaccination programme with the bivalent vaccine is likely cost-effective, with an incremental cost-effectiveness ratio of SGD$19 007 (95 % UI: 10 164-30 633) per QALY gained. The findings suggest the need to engage experts to examine, in detail, the cost-effectiveness of gender-neutral vaccination programmes in Singapore. Issues of drug licensing, feasibility, gender equity, global vaccine supplies, and the global trend towards disease elimination/eradication should also be considered. This model provides a simplified method for resource-strapped countries to gain a preliminary estimate of the cost-effectiveness of a gender-neutral HPV vaccination programme before investing resources for further research.

RESUMO

PURPOSE OF REVIEW: Understanding stigma is important for improving HIV care services and gaps in HIV service delivery have been attributed to stigma. This review article synthesizes recent evidence on stigma and its implications for HIV service design and delivery. Given the intersectional nature of stigma, we will focus on HIV stigma as well as related forms of stigma based on one's race, sexual identity, gender identity and other identities. RECENT FINDINGS: Stigma remains a barrier to achieving equity in HIV services. Individualistic measures of stigma remain influential and are associated with barriers to accessing HIV health services. Recent work also highlights stigma measured at a structural level and its impact on HIV services contexts. Individuals situated at intersections of marginalized identities continue to face greatest injustices, and although intersectional approaches have been adapted to design services at a micro level, few focus on structural change. Recent evidence for mitigating stigma indicates some success for psychosocial interventions that target internalized stigma. Furthermore, community-led approaches show promise in addressing stigma that manifests in HIV health services settings. SUMMARY: Interventions that address individual-level stigma and structural stigma are needed. Theoretical and applied antistigma research is needed to make HIV services more equitable.

RESUMO

BACKGROUND: Misinformation related to the COVID-19 pandemic has accelerated global public concern and panic. The glut of information, or "infodemic," has caused concern for authorities due to its negative impacts on COVID-19 prevention and control, spurring calls for a greater scholarly focus on health literacy during the pandemic. Nevertheless, few studies have sought to qualitatively examine how individuals interpreted and assimilated health information at the initial wave of COVID-19 restrictions. OBJECTIVE: We developed this qualitative study adopting chat-based focus group discussions to investigate how individuals interpreted COVID-19 health information during the first wave of COVID-19 restrictions. METHODS: We conducted a qualitative study in Singapore to investigate how individuals perceive and interpret information that they receive on COVID-19. Data were generated through online focus group discussions conducted on the mobile messaging smartphone app WhatsApp. From March 28 to April 13, 2020, we held eight WhatsApp-based focus groups (N=60) with participants stratified by age groups, namely 21-30 years, 31-40 years, 41-50 years, and 51 years and above. Data were thematically analyzed. RESULTS: A total of four types of COVID-19 health information were generated from the thematic analysis, labeled as formal health information, informal health information, suspicious health information, and fake health information, respectively. How participants interpreted these categories of information depended largely on the perceived trustworthiness of the information source as well as the perceived veracity of information. Both factors were instrumental in determining individuals' perceptions, and their subsequent treatment and assimilation of COVID-19-related information. CONCLUSIONS: Both perceived trustworthiness of the information source and perceived veracity of information were instrumental concepts in determining one's perception, and thus subsequent treatment and assimilation of such information for one's knowledge of COVID-19 or the onward propagation to their social networks. These findings have implications for how policymakers and health authorities communicate with the public and deal with fake health information in the context of COVID-19.

RESUMO

Although sexual health programming and clinical sexually transmitted infections (STIs) services have traditionally been developed through 'top-down' approaches, there is emerging evidence that participatory approaches benefit the development and implementation of such services. Although other studies have already highlighted the benefits of participation in research and implementation of clinical STIs services delivery, this narrative review focuses on how community participation in clinical STIs services delivery has been operationalised and on the various aspects of clinical STIs services delivery in which participatory processes have been implemented. A PubMed search was conducted in January 2022 using the search terms that reflected the topic of participatory processes in clinical STIs services delivery to identify relevant papers. Only peer-reviewed papers published in English were reviewed, and no timeframe was selected. After reviewing existing studies, we identified how community participation has been incorporated across stages of clinical STIs service delivery, including planning, developing, delivering, evaluating, and scaling up, as well as gaps and challenges faced in implementing such approaches. This review highlighted how a wide range of participatory processes characterised by varying depths of participation have been used in the above processes. Challenges such as funding, socio-cultural barriers, technical barriers and the digital divide, issues of quality assurance, and standardising the measurement of participation remain, which may impede the uptake of participatory processes in clinical STIs services.

RESUMO

BACKGROUND: The coronavirus diseases 2019 (COVID-19) pandemic resulted in lockdowns worldwide, with reports suggesting a concomitant increase in the incidence of intimate partner violence (IPV). This study was part of the International Sexual and Reproductive Health (I-SHARE) Consortium, examining IPV and its correlates before and during lockdown in April 2020. METHODS: This cross-sectional observational study, conducted online during August-September 2020, recruited 259 participants from Singapore who reported having a steady partner. Alongside socio-demographic data before and during COVID-19 lockdown, the respondents self-reported their encounters with partner violence. Partner violence was measured using an adapted six-item version of the WHO IPV scale. RESULTS: Data revealed an incidence of 17.2%, 25.0%, 16.7%, 17.6%, 17.5% and 18.5% of restriction of contact with others, verbal abuse, restriction of access to finances, physical violence, pressured sex and forced sex, respectively, before COVID-19 lockdown. During lockdown, incidences of these forms of violence were 17.4%, 19.8%, 14.7%, 13.5%, 14.7% and 15.2%, respectively. Multivariable analyses showed that being younger, being non-heterosexual, and having more children and adolescents at home were significantly associated with partner violence both before and during lockdown. Analyses also revealed that being of Chinese ethnicity and having a monthly income above SGD3000 were not significantly correlated to partner violence before lockdown but emerged as significant during lockdown. CONCLUSIONS: Some sociodemographic factors were associated with violence regardless of lockdown, while other factors were exacerbated by lockdown. Interventions should consider these key correlates of partner-based violence, ensuring adequate and appropriate support for vulnerable populations both within and outside of lockdown contexts.

RESUMO

BACKGROUND: Gay, bisexual, and other men who have sex with men (GBMSM) are at disproportionately higher risk of acquiring HIV and other sexually transmitted infections (STI). While HIV/STI testing rates among GBMSM are increasing worldwide, they remain suboptimal in a variety of settings. While many studies have attempted to evaluate the efficacy of a variety of community-based campaigns, including peer and reminder-based interventions on HIV/STI testing, however few have attempted to do so for a web drama series. OBJECTIVE: This study evaluates the effectiveness of a popular web drama video series developed by a community-based organization in Singapore for GBMSM on HIV and other STI testing behaviors. METHODS: The study is a pragmatic, randomized controlled trial to evaluate a popular web drama video series developed by a community-based organization in Singapore for GBMSM. A total of 300 HIV-negative, GBMSM men in Singapore aged 18 to 29 years old were recruited and block-randomized into the intervention (n=150) and control arms (n=150). Primary outcomes included changes in self-reported intention to test for, actual testing for, and regularity of testing for HIV, syphilis, chlamydia or gonorrhea, while secondary outcomes include changes in a variety of other knowledge-based and psychosocial measures at the end of the study period. RESULTS: Overall, 83.3% (125/150) of participants in the intervention arm completed the proof of completion survey, compared to 88.7% (133/150) in the control arm. We found improvements in self-reporting as a regular (at least yearly) tester for HIV (15.9% difference, 95% CI, 3.2% to 28.6%; P=.02), as well as chlamydia or gonorrhea (15.5% difference, 95% CI, 4.2% to 26.9%; P=.009), indicating that the intervention had positively impacted these outcomes compared to the control condition. We also found improvements in participants' intentions to test for HIV (16.6% difference, 95% CI, 4.3% to 28.9%; P=.009), syphilis (14.8% difference, 95% CI, 3.2% to 26.4%; P=.01), as well as chlamydia or gonorrhea (15.4% difference, 95% CI, 4.2% to 26.6%; P=.008), in the next 3 months, indicating that the intervention was effective in positively impacting intention for HIV and other STI testing among participants. CONCLUSIONS: There are clear benefits for promoting intentions to test regularly and prospectively on a broad scale through this intervention. This intervention also has potential to reach GBMSM who may not have access to conventional HIV and other STI prevention messaging, which have typically been implemented at sex-on-premises venues, bars, clubs, and in sexual health settings frequented by GBMSM. When coupled with community or population-wide structural interventions, the overall impact on testing will likely be significant.
