A crowdsourced intervention to promote hepatitis B and C testing among men who have sex with men in China: study protocol for a nationwide online randomized controlled trial

Differences in willingness to pay for various types of carbon-labeled products: A dynamic perspective

Carbon labeling (CL) is a carbon reduction policy with development potential that has not yet been widely promoted worldwide. This study explores the trend of consumers' willingness to pay (WTP) for different types of carbon-labeled products from a dynamic perspective, to provide a reference for future pilot projects. The research team collected 3788 valid questionnaires from China's first-tier cities spanning a five-year period and used interval regression to analyze the impact and change of consumer traits on WTP for the four types of carbon-labeled products in 2019 and 2024. The bootstrap method was further used to examine the impact mechanisms to explore ways to improve the current situation. This study found that (1) WTP for food, textiles, electronics, and other household products with CL generally decreased from 2019 to 2024. Textiles and electronics experienced a smaller decline, while food and other household products witnessed larger decreases. (2) The effect of consumer characteristics on WTP changes from 2019 to 2024. Consumers' frequency of low-carbon behaviors no longer significantly affects WTP across all product categories, while attitudes toward CL only affect textiles and electronics. (3) Consumers' perceived environmental value is the mechanism by which personal traits affect WTP. Finally, based on the findings, this study suggests that the selection of textiles and electronics as a pilot product is more likely to be accepted by consumers and that emphasis should be placed on the promotion of the environmental values of CL.

Hurting myself to cope: Using network analysis to understand the association between perceived stigma and non-suicidal self-injury functions among men who have sex with men in China

Prior studies have demonstrated that perceived stigma is robustly associated with risky and life-threatening behaviors, including non-suicidal self-injury (NSSI), among men who have sex with men (MSM). However, studies regarding the relationship between perceived stigma and NSSI are limited. The present study aimed to investigate the network structure of perceived stigma and NSSI functions, along with bridge nodes, to elucidate how they co-exist. A sample of 2610 Chinese MSM (mean age = 23.99, age range: 18-68 years) was recruited from an online survey platform. All participants completed a web-based survey with measures of perceived stigma and NSSI functions. Results indicated that 'negative attitudes towards homosexuality' and 'disappointment in gay son' were identified as the most central nodes in the perceived stigma network, whereas 'seeking attention' and 'influencing others to change' ranked highest on centrality in the NSSI network. Two bridge connections were exhibited within the combined perceived stigma and NSSI network model: 'unwelcoming in public' and 'avoiding unpleasant tasks' from perceived stigma and NSSI communities, respectively. This is among the first studies investigating the co-occurrence between perceived stigma and NSSI from the network approach. Our findings provide an empirically-based perspective on the importance of family- and community-based interventions, with potential clinical implications for reducing NSSI among sexual and gender minority groups.

Associations among internalized and perceived stigma, state mindfulness, self-efficacy, and depression symptoms among men who have sex with men in China: A serial mediation model

Previous research has demonstrated that stigma is strongly related to depressive symptoms among men who have sex with men (MSM). However, data are limited regarding the associations between stigma, state mindfulness, self-efficacy, and depression symptoms. The current study aimed to analyze state mindfulness and self-efficacy as possible mediators between internalized and perceived stigma and depression symptoms. A sample of 2610 Chinese MSM (Mage = 23.99, SD = 6.09, age range: 18-68 years) was recruited from an online survey platform and completed the HIV and Homosexuality Related Stigma Scale, Patient Health Questionnaire-9, the short version of Five Facet Mindfulness Questionnaire, and the Chinese General Self-Efficacy Scale. Results indicated that state mindfulness significantly mediated the linkage between internalized and perceived stigma and depressive symptoms, and self-efficacy significantly mediated the relation between state mindfulness and depression symptoms. Furthermore, internalized and perceived stigma were associated with depression symptoms through a serial mediation of state mindfulness and self-efficacy. This study highlights that state mindfulness and self-efficacy might play important roles in the psychological response of MSM to stigmatization and psychopathology symptoms.

A randomized controlled trial enhancing viral hepatitis testing in primary care via digital crowdsourced intervention

Despite the availability of hepatitis B virus (HBV) and hepatitis C virus (HCV) testing in primary care, testing rates in China remain low. Social media is an inexpensive means of disseminating information and could facilitate hepatitis testing promotion. We evaluated the capacity of digitally crowdsourced materials to promote HBV/HCV testing uptake via a randomized controlled trial (identifier: ChiCTR1900025771), which enrolled 750 Chinese primary care patients. We randomized patients (1:1) to receive crowdsourced HBV/HCV promotion materials through social media or facility-based care without promotional materials for four weeks. Exposure to all intervention materials was associated with increased odds of HBV (aOR = 1.79, 95% CI: 1.09–3.00) and HCV (aOR = 1.95, 95% CI: 1.29–2.99) testing compared to facility-based care. There was a significant reduction in hepatitis stigma among intervention group participants (HBV slope: −0.15, p < 0.05; and HCV slope: −0.13, p < 0.05). Digitally crowdsourced promotion messages could enhance hepatitis testing uptake and should be considered in hepatitis reduction strategies.

Ethical Issues in Social Media Recruitment for Clinical Studies: Ethical Analysis and Framework

BACKGROUND

Social media recruitment for clinical studies holds the promise of being a cost-effective way of attracting traditionally marginalized populations and promoting patient engagement with researchers and a particular study. However, using social media for recruiting clinical study participants also poses a range of ethical issues.

OBJECTIVE

This study aims to provide a comprehensive overview of the ethical benefits and risks to be considered for social media recruitment in clinical studies and develop practical recommendations on how to implement these considerations.

METHODS

On the basis of established principles of clinical ethics and research ethics, we reviewed the conceptual and empirical literature for ethical benefits and challenges related to social media recruitment. From these, we derived a conceptual framework to evaluate the eligibility of social media use for recruitment for a specific clinical study.

RESULTS

We identified three eligibility criteria for social media recruitment for clinical studies: information and consent, risks for target groups, and recruitment effectiveness. These criteria can be used to evaluate the implementation of a social media recruitment strategy at its planning stage. We have discussed the practical implications of these criteria for researchers.

CONCLUSIONS

The ethical challenges related to social media recruitment are context sensitive. Therefore, social media recruitment should be planned rigorously, taking into account the target group, the appropriateness of social media as a recruitment channel, and the resources available to execute the strategy.

'Mindfulness Living with Insomnia': an mHealth intervention for individuals with insomnia in China: a study protocol of a randomised controlled trial

INTRODUCTION

Insomnia has a remarkably negative effect on the work, quality of life and psychosomatic health of individuals, and imposes a substantial economic burden on society. Mindfulness-based interventions (MBIs) have proven beneficial in the treatment of insomnia. However, the effect of mobile or online-based (mHealth) MBIs requires further verification. This study will evaluate the effectiveness of an mHealth MBI, 'Mindful Living with Insomnia' (MLWI), relative to that of mHealth cognitive behavioural therapy for insomnia (CBT-I).

METHODS AND ANALYSIS

The study is an mHealth, randomised controlled trial. Two hundred and fifty participants will be allocated randomly and equally to either the MLWI or CBT-I group. The intervention will involve 12 sessions over a 6-week course, with 2, 30 min sessions per week. The primary outcomes are sleep quality, severity of insomnia symptoms and sleep activity, according to the Pittsburgh Sleep Quality Index, Insomnia Severity Index and sleep tracker Mi Smart Band, respectively. The secondary outcomes are perceived stress, anxiety, depression and mindfulness. Outcomes will be evaluated at the baseline, end of the intervention period and at the 3-month follow-up. Data analyses will include covariance, regression analysis, χ², t-test and Pearson's correlations. Participants will be recruited from January to June 2022, or until the recruitment process is complete. The follow-up will be completed in December 2022. All trial results should be available by the end of December 2022.

ETHICS AND DISSEMINATION

Full approval for this study has been obtained from the Ethics Committee at The Third Xiangya Hospital, Central South University, Changsha, China (21010). Study results will be disseminated via social media and peer-reviewed publications.

Feasibility and Acceptability of a Cognitive Behavioral Therapy-Based Smartphone App for Smoking Cessation in China: A Single-Group Cohort Study

BACKGROUND

Previous research has suggested that mobile phone applications (apps) may potentially increase quit rates. The purpose of this single-group cohort study sought to examine the feasibility and acceptability of a novel smartphone-based smoking cessation app designed for smoking cessation in China: smoking quit rate.

METHODS

A total of 180 smokers from two cities of mainland China with willingness to make a quit attempt were invited to this smoking cessation app program, a cognitive behavioral theory (CBT)-based smoking cessation intervention via a smartphone app. Participants received 37- to 44-day intervention (including 7- to 14-day pre-quit preparation and 33-day intervention from quit date). Feasibility and acceptability of the program, and smoking status were assessed at baseline stage (initial installation), pre-quit stage, and post-quit stage (days 7, 15, and 33 after quit date).

RESULTS

A total of 163 (90.6%) participants completed the study. Among them, 76-89% of the participants logged into the app ≥1 time per day across stages (at baseline, during pre-quit stage, and on days 7, 15, and 33 of post-quit stage); approximately 90% of the participants were satisfied with the app across stages. A significant rise in self-reported overall satisfaction with the app is observed from baseline (93% at Time 1) to the end of the program (98% at Time 2, 33 days after quit date) (p = 0.021). Participants who believed/agreed this app can help them to quit smoking significantly increased from 69% at baseline to 97% at day 33 after quit date (p < 0.001). Participants were satisfied with most (80-90%) of the features, especially the information feature. Intention-to-treat analysis showed that the percentage of 33-day self-reported continuous prevalence abstinence was 63.9%, and 7-day point prevalence abstinence rate was 81.7, 87.2, and 77.8% on days 7, 15, and 33 after quit date, respectively.

CONCLUSIONS

This study demonstrated the feasibility and acceptability of the smartphone app intervention for smoking cessation and introduced a new digital treatment model, which is expected to overcome barriers facing accessing traditional in-person smoking cessation services and extend nationwide smoking cessation services in China.

Brief mindfulness-based intervention of 'STOP (Stop, Take a Breath, Observe, Proceed) touching your face': a study protocol of a randomised controlled trial

INTRODUCTION

Face-touching behaviour often happens frequently and automatically, and poses potential risk for spreading infectious disease. Mindfulness-based interventions (MBIs) have shown its efficacy in the treatment of behaviour disorders. This study aims to evaluate an online mindfulness-based brief intervention skill named 'STOP (Stop, Take a Breath, Observe, Proceed) touching your face' in reducing face-touching behaviour.

METHODS AND ANALYSIS

This will be an online-based, randomised, controlled, trial. We will recruit 1000 participants, and will randomise and allocate participants 1:1 to the 'STOP touching your face' (both 750-word text and 5 min audio description by online) intervention group (n=500) and the wait-list control group (n=500). All participants will be asked to monitor and record their face-touching behaviour during a 60 min period before and after the intervention. Primary outcome will be the efficacy of short-term mindfulness-based 'STOP touching your face' intervention for reducing the frequency of face-touching. The secondary outcomes will be percentage of participants touching their faces; the correlation between the psychological traits of mindfulness and face-touching behaviour; and the differences of face-touching behaviour between left-handers and right-handers. Analysis of covariance, regression analysis, χ² test, t-test, Pearson's correlations will be applied in data analysis. We will recruit 1000 participants from April to July 2020 or until the recruitment process is complete. The follow-up will be completed in July 2020. We expect all trial results to be available by the end of July 2020.

ETHICS AND DISSEMINATION

The study protocol has been approved by the Ethics Committee of Sir Run Run Shaw Hospital, an affiliate of Zhejiang University, Medical College (No. 20200401-32). Study results will be disseminated via social media and peer-reviewed publications.

When Public Health Research Meets Social Media: Knowledge Mapping From 2000 to 2018

BACKGROUND

Social media has substantially changed how people confront health issues. However, a comprehensive understanding of how social media has altered the foci and methods in public health research remains lacking.

OBJECTIVE

This study aims to examine research themes, the role of social media, and research methods in social media-based public health research published from 2000 to 2018.

METHODS

A dataset of 3419 valid studies was developed by searching a list of relevant keywords in the Web of Science and PubMed databases. In addition, this study employs an unsupervised text-mining technique and topic modeling to extract research themes of the published studies. Moreover, the role of social media and research methods adopted in those studies were analyzed.

RESULTS

This study identifies 25 research themes, covering different diseases, various population groups, physical and mental health, and other significant issues. Social media assumes two major roles in public health research: produce substantial research interest for public health research and furnish a research context for public health research. Social media provides substantial research interest for public health research when used for health intervention, human-computer interaction, as a platform of social influence, and for disease surveillance, risk assessment, or prevention. Social media acts as a research context for public health research when it is mere reference, used as a platform to recruit participants, and as a platform for data collection. While both qualitative and quantitative methods are frequently used in this emerging area, cutting edge computational methods play a marginal role.

CONCLUSIONS

Social media enables scholars to study new phenomena and propose new research questions in public health research. Meanwhile, the methodological potential of social media in public health research needs to be further explored.

Targeted client communication via mobile devices for improving sexual and reproductive health

BACKGROUND

The burden of poor sexual and reproductive health (SRH) worldwide is substantial, disproportionately affecting those living in low- and middle-income countries. Targeted client communication (TCC) delivered via mobile devices (MD) (TCCMD) may improve the health behaviours and service use important for sexual and reproductive health.

OBJECTIVES

To assess the effects of TCC via MD on adolescents' knowledge, and on adolescents' and adults' sexual and reproductive health behaviour, health service use, and health and well-being.

SEARCH METHODS

In July/August 2017, we searched five databases including The Cochrane Central Register of Controlled Trials, MEDLINE and Embase. We also searched two trial registries. A search update was carried out in July 2019 and potentially relevant studies are awaiting classification.

SELECTION CRITERIA

We included randomised controlled trials of TCC via MD to improve sexual and reproductive health behaviour, health service use, and health and well-being. Eligible comparators were standard care or no intervention, non-digital TCC, and digital non-targeted communication.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures recommended by Cochrane, although data extraction and risk of bias assessments were carried out by one person only and cross-checked by a second. We have presented results separately for adult and adolescent populations, and for each comparison.

MAIN RESULTS

We included 40 trials (27 among adult populations and 13 among adolescent populations) with a total of 26,854 participants. All but one of the trials among adolescent populations were conducted in high-income countries. Trials among adult populations were conducted in a range of high- to low-income countries. Among adolescents, nine interventions were delivered solely through text messages; four interventions tested text messages in combination with another communication channel, such as emails, multimedia messaging, or voice calls; and one intervention used voice calls alone. Among adults, 20 interventions were delivered through text messages; two through a combination of text messages and voice calls; and the rest were delivered through other channels such as voice calls, multimedia messaging, interactive voice response, and instant messaging services. Adolescent populations TCCMD versus standard care TCCMD may increase sexual health knowledge (risk ratio (RR) 1.45, 95% confidence interval (CI) 1.23 to 1.71; low-certainty evidence). TCCMD may modestly increase contraception use (RR 1.19, 95% CI 1.05 to 1.35; low-certainty evidence). The effects on condom use, antiretroviral therapy (ART) adherence, and health service use are uncertain due to very low-certainty evidence. The effects on abortion and STI rates are unknown due to lack of studies. TCCMD versus non-digital TCC (e.g. pamphlets) The effects of TCCMD on behaviour (contraception use, condom use, ART adherence), service use, health and wellbeing (abortion and STI rates) are unknown due to lack of studies for this comparison. TCCMD versus digital non-targeted communication The effects on sexual health knowledge, condom and contraceptive use are uncertain due to very low-certainty evidence. Interventions may increase health service use (attendance for STI/HIV testing, RR 1.61, 95% CI 1.08 to 2.40; low-certainty evidence). The intervention may be beneficial for reducing STI rates (RR 0.61, 95% CI 0.28 to 1.33; low-certainty evidence), but the confidence interval encompasses both benefit and harm. The effects on abortion rates and on ART adherence are unknown due to lack of studies. We are uncertain whether TCCMD results in unintended consequences due to lack of evidence. Adult populations TCCMD versus standard care For health behaviours, TCCMD may modestly increase contraception use at 12 months (RR 1.17, 95% CI 0.92 to 1.48) and may reduce repeat abortion (RR 0.68 95% CI 0.28 to 1.66), though the confidence interval encompasses benefit and harm (low-certainty evidence). The effect on condom use is uncertain. No study measured the impact of this intervention on STI rates. TCCMD may modestly increase ART adherence (RR 1.13, 95% CI 0.97 to 1.32, low-certainty evidence, and standardised mean difference 0.44, 95% CI -0.14 to 1.02, low-certainty evidence). TCCMD may modestly increase health service utilisation (RR 1.17, 95% CI 1.04 to 1.31; low-certainty evidence), but there was substantial heterogeneity (I2 = 85%), with mixed results according to type of service utilisation (i.e. attendance for STI testing; HIV treatment; voluntary male medical circumcision (VMMC); VMMC post-operative visit; post-abortion care). For health and well-being outcomes, there may be little or no effect on CD4 count (mean difference 13.99, 95% CI -8.65 to 36.63; low-certainty evidence) and a slight reduction in virological failure (RR 0.86, 95% CI 0.73 to 1.01; low-certainty evidence). TCCMD versus non-digital TCC No studies reported STI rates, condom use, ART adherence, abortion rates, or contraceptive use as outcomes for this comparison. TCCMD may modestly increase in service attendance overall (RR: 1.12, 95% CI 0.92-1.35, low certainty evidence), however the confidence interval encompasses benefit and harm. TCCMD versus digital non-targeted communication No studies reported STI rates, condom use, ART adherence, abortion rates, or contraceptive use as outcomes for this comparison. TCCMD may increase service utilisation overall (RR: 1.71, 95% CI 0.67-4.38, low certainty evidence), however the confidence interval encompasses benefit and harm and there was considerable heterogeneity (I2 = 72%), with mixed results according to type of service utilisation (STI/HIV testing, and VMMC). Few studies reported on unintended consequences. One study reported that a participant withdrew from the intervention as they felt it compromised their undisclosed HIV status.

AUTHORS' CONCLUSIONS

TCCMD may improve some outcomes but the evidence is of low certainty. The effect on most outcomes is uncertain/unknown due to very low certainty evidence or lack of evidence. High quality, adequately powered trials and cost effectiveness analyses are required to reliably ascertain the effects and relative benefits of TCC delivered by mobile devices. Given the sensitivity and stigma associated with sexual and reproductive health future studies should measure unintended consequences, such as partner violence or breaches of confidentiality.

Crowdsourcing to promote hepatitis C testing and linkage-to-care in China: a randomized controlled trial protocol

Background

Hepatitis C virus (HCV) is a growing public health problem with a large disease burden worldwide. In China many people living with HCV are unaware of their hepatitis status and not connected to care and treatment. Crowdsourcing is a technique that invites the public to create health promotion materials and has been found to increase HIV testing uptake, including in China. This trial aims to evaluate crowdsourcing as a strategy to improve HCV awareness, testing and linkage-to-care in China.

Methods

A randomized controlled, two-armed trial (RCT) is being conducted in Shenzhen with 1006 participants recruited from primary care sectors of The University of Hong Kong-Shenzhen Hospital. Eligible participants are ≥30 years old; a resident in Shenzhen for at least one month after recruitment; no screening for HCV within the past 12 months and not known to have chronic HCV; and, having a WeChat social media account. Allocation is 1:1. Both groups will be administered a baseline and a follow-up survey (4-week post-enrollment). The intervention group will receive crowdsourcing materials to promote HCV testing once a week for two weeks and feedback will be collected thereafter, while the control group will receive no promotional materials. Feedback collected will be judged by a panel and selected to be implemented to improve the intervention continuously.

Those identified positive for HCV antibodies will be referred to gastroenterologists for confirmation and treatment. The primary outcome will be confirmed HCV testing uptake, and secondary outcomes include HCV confirmatory testing and initiation of HCV treatment with follow-ups with specialist providers. Data will be collected on Survey Star^@ via mobile devices.

Discussion

This will be the first study to evaluate the impact of crowdsourcing to improve viral hepatitis testing and linkage-to-care in the health facilities. This RCT will contribute to the existing literature on interventions to improve viral hepatitis testing in primary care setting, and inform future strategies to improve HCV care training for primary care providers in China.

Social innovation in diagnostics: three case studies

Background

Diagnostics are essential for identifying and controlling diseases. However, limited access to diagnostics hinders public health efforts in many settings. Social innovation may provide a framework for expanding access to diagnostics in the global south. Here social innovation is defined as implementing a known public health tool via a novel, community-driven technique.

Main Body

In this article, we discuss three diverse cases that show the potential for using social innovation in diagnostics. The cases chosen for inclusion here demonstrate the importance of social innovation in diagnostics across different geographic, cultural, and health system contexts. They include malaria testing via schools in Malawi, cervical human papillomavirus (HPV) sample self-collection in Peru, and crowdsourcing human immunodeficiency virus (HIV) testing in China. For each case, we present the public health problem and the impact of using social innovation to increase accessibility of diagnostics. We discuss implications of each diagnostic approach and the importance of social innovation in creating these potential solutions. We argue that social innovation is useful in improving the delivery of essential diagnostic tools in low- and middle-income countries.

Conclusions

Interventions in Malawi, Peru, and China suggest social innovation increases uptake of diagnostics. The same tools and principles utilized in these cases can be adapted for use in other contexts. Such diagnostic innovations may help improve identification of and linkage to care for many diseases. The approach presents a unique opportunity to better address public health issues and increase accessibility in LMIC health systems.

Digital health for sexually transmitted infection and HIV services: a global scoping review

PURPOSE OF REVIEW

The current study aimed to review how digital health has been used for sexually transmitted infection (STI)/HIV prevention, testing, and treatment.

RECENT FINDINGS

A scoping review was conducted by searching five databases for peer-reviewed literature published between March 2018 to August 2019. 23 out of 258 studies met the inclusion criteria and were assessed. Six studies used digital platform to enhance STI/HIV prevention messaging; four studies found that digital health can provide vivid promotional information and has been instrumental in increasing the accessibility and acceptability of STI/HIV testing; three studies reported digital health provides a channel to understand and interpret the discourses on preexposure prophylaxis (PrEP) and increase PrEP uptake; three studies focused on refining big data algorithms for surveillance; four studies reported on how digital interventions could be used to optimize clinical interventions; and four studies found digital interventions can be used to assist mental health services.

SUMMARY

Digital health is a powerful and versatile tool that can be utilized in the production of high-quality, innovative strategies on STIs and HIV services. Future studies should consider focusing on strategies and implementations that leverage digital platforms for network-based interventions, in addition to recognizing the norms of individual digital intervention platforms.

A crowdsourced intervention to decrease hepatitis B stigma in men who have sex with men in China: A cohort study

Stigma against people with hepatitis B virus (HBV) is a barrier to prevention, diagnosis and treatment of HBV in China. Our study examined an innovative intervention to reduce HBV stigma among men who have sex with men (MSM) in China. We extracted data from a randomized controlled trial conducted in May 2018, where the intervention consisted of crowdsourced images and videos to promote viral hepatitis testing and reduce HBV stigma. HBV stigma was assessed using a 20-item scale at baseline and four weeks post-enrolment. Participants were divided into three groups based on their exposure to intervention: full exposure, partial exposure and no exposure. Linear regression was used to determine associations between baseline stigma and participant characteristics. Data from 470 MSM were analysed. Mean participant age was 25 years old and 56% had less education than a college bachelor's degree. Full exposure to intervention was associated with significant stigma reduction (adjusted beta = -3.49; 95% CI = -6.11 to -0.87; P = .01), while partial exposure led to stigma reduction that was not statistically significant. The mean stigma score was 50.6 (SD ± 14.7) at baseline, and stigma was most prominent regarding physical contact with HBV carriers. Greater HBV stigma was associated with not having a recent doctor's visit (adjusted beta = 4.35, 95% CI = 0.19 to 8.52; P = .04). In conclusion, crowdsourcing can decrease HBV stigma among MSM in China and may be useful in anti-stigma campaigns for vulnerable populations in low- and middle-income countries.

A crowdsourced intervention to promote hepatitis B and C testing among men who have sex with men in China: A nationwide online randomized controlled trial

BACKGROUND

Crowdsourcing may be an effective strategy to develop test promotion materials. We conducted an online randomized controlled trial (RCT) to evaluate a crowdsourced intervention to promote hepatitis B virus (HBV) and hepatitis C virus (HCV) testing among men who have sex with men (MSM) in China.

METHODS

MSM never previously tested for hepatitis were recruited through social media. Eligible men were randomized to receive an online crowdsourced intervention or no testing promotion materials. Outcomes including self-reported and confirmed HBV and HCV test uptake were assessed after four weeks. Odds ratios (OR) with 95% confidence intervals (95% CI) of men achieving primary and secondary outcomes between the intervention and control arms were calculated.

FINDINGS

556 eligible men were enrolled. Overall, 17•4% (97/556) of men self-reported HBV and HCV testing and 7•9% (44/556) confirmed HBV and HCV test uptake. The intervention was seen by 72•1% and 29•0% of men in the intervention and control arms, respectively. In intention-to-treat analysis, confirmed HBV and HCV test uptake was similar between the two arms, both when using a missing=failure approach (OR 0•98, 95% CI 0•53-1•82) or multiple imputation (OR 1•46, 95% CI 0•72-2•95).

INTERPRETATION

This RCT extends the literature by developing and evaluating an intervention to spur hepatitis testing in a middle-income country with a high burden of hepatitis. Overall test uptake among MSM in China was similar to previous interventions promoting hepatitis testing in high-income countries. We found frequent intervention sharing, complicating interpretation of the results, and the role of crowdsourcing to promote hepatitis testing remains unclear.

Crowdsourcing to Improve HIV and Sexual Health Outcomes: a Scoping Review

PURPOSE OF REVIEW

This review synthesizes evidence on the use of crowdsourcing to improve HIV/sexual health outcomes.

RECENT FINDINGS

We identified 15 studies, including four completed randomized controlled trials (RCTs), one planned RCT, nine completed observational studies, and one planned observational study. Three of the four RCTs suggested that crowdsourcing is an effective, low-cost approach for improving HIV testing and condom use among key populations. Results from the observational studies revealed diverse applications of crowdsourcing to inform policy, research, and intervention development related to HIV/sexual health services. Crowdsourcing can be an effective tool for informing the design and implementation of HIV/sexual health interventions, spurring innovation in sexual health research, and increasing community engagement in sexual health campaigns. More research is needed to examine the feasibility, acceptability, and effectiveness of crowdsourcing interventions, particularly in low- and middle-income countries.

Crowdsourcing in medical research: concepts and applications

Crowdsourcing shifts medical research from a closed environment to an open collaboration between the public and researchers. We define crowdsourcing as an approach to problem solving which involves an organization having a large group attempt to solve a problem or part of a problem, then sharing solutions. Crowdsourcing allows large groups of individuals to participate in medical research through innovation challenges, hackathons, and related activities. The purpose of this literature review is to examine the definition, concepts, and applications of crowdsourcing in medicine. This multi-disciplinary review defines crowdsourcing for medicine, identifies conceptual antecedents (collective intelligence and open source models), and explores implications of the approach. Several critiques of crowdsourcing are also examined. Although several crowdsourcing definitions exist, there are two essential elements: (1) having a large group of individuals, including those with skills and those without skills, propose potential solutions; (2) sharing solutions through implementation or open access materials. The public can be a central force in contributing to formative, pre-clinical, and clinical research. A growing evidence base suggests that crowdsourcing in medicine can result in high-quality outcomes, broad community engagement, and more open science.
