Relationships of work stress and interpersonal needs with industrial workers' mental health: a moderated mediation model.

OBJECTIVES: This study explores whether feelings of defeat (i.e., a sense of failed struggle and losing rank; referred to as defeat for simplicity) mediated the effect of work stress on depression/anxiety, the effect of interpersonal needs on depression/anxiety for Chinese industrial workers, and the possible moderating role of social support. METHOD: A cross-sectional study was conducted in Shenzhen, China in 2019, in total, 2023 industrial workers (of 2700 invited; response rate = 75%) completed a self-administered survey consisted of Job Stress Scale, Interpersonal Needs Questionnaire, Defeat Scale, Centre for Epidemiological Studies Depression Scale, Generalized Anxiety Disorder Scale, two face-valid questions for social support, as well as sociodemographic information. Moderated mediation model was tested and loop plots were applied to probe into the conditional effects of work and interpersonal stress on depression and anxiety symptoms. RESULT: Both the direct and indirect effect of work stress on depression and anxiety through defeat were significant (Work stress→ Depression: B = 0.035, p < .001, Work stress→ Defeat→ Depression: B = 0.034, p < .001; Work stress→ Anxiety: B = 0.038, p < .001, Work stress→ Defeat→ Anxiety: B = 0.045, p < .001). Meanwhile, defeat mediated the relationship of interpersonal needs with depression partially and the relationship of interpersonal needs with anxiety totally (Interpersonal needs→ Anxiety: B = 0.133, p < .001, Interpersonal needs→ Defeat→ Anxiety: B = 0.010, p = .537). Social support moderated the indirect path between interpersonal needs and depression/anxiety and buffered the effect. CONCLUSION: The mediating role of defeat and the moderator role of social support in the relationship between stress and depression/anxiety were confirmed in industrial workers. Workers who reported more work and interpersonal stress would report more defeat feelings, and then exhibited more depression and anxiety symptoms; this mediation effect was stronger for those who had lower social support, respectively.

When Epidemic Outbreaks Meet Social Media: Collective Illness Narratives on WeChat During COVID-19 Omicron Infection in China.

This study investigates the landscape of collective illness narratives on social media in China during December 2022 and January 2023, when nearly one billion people were infected with the COVID-19 Omicron virus. By analyzing 655 private social media posts, conducting in-depth interviews with 50 individuals, and organizing 6 focus group discussions with 24 participants, this study explores how COVID-19 Omicron infection became normalized and widely discussed on private social media platforms, notably WeChat Moments. This study unveils distinct features that arise when illness narratives and social media intersect and reveals how people exercised moral imagination and depathologized perception in social media illness narratives. The article provides narrative dynamics during the pandemic in a collective manner and sheds light on the reshaping of illness narratives in the era of social media, offering insights for future pandemic responses.

Sexual risk behaviours among factory workers in Shenzhen, China: a cross-sectional study.

BACKGROUND: Factory workers are a key population for HIV transmission in China, as they often engage in sexual risk behaviours. This study aims to evaluate sexual risk behaviours and associated factors among factory workers in Shenzhen, China. METHODS: A cross-sectional study was conducted by using multi-stage stratified cluster random sampling. Full-time workers aged ≥18years were eligible to participate in the study. A self-administered questionnaire was used to collect information. Univariate and multivariable logistic regression were applied to assess factors associated with sexual risk behaviours. RESULTS: A total of 2029 factory workers were included. Mean age was 37.2 (±4.4)years; 48.5% were men. Two-thirds (64.9%) had had vaginal intercourse. Their sexual risk behaviours included condomless sex with casual partners in the last sex episode (23.6%), multiple sex partners (11.5%) and engaging in commercial sex (8.4%), in the past year. Having HIV/AIDS knowledge (adjusted odds ratio (AOR) 0.41, 95% confidence interval (CI) 0.24-0.70) and using a condom at sexual debut (AOR 0.08, 95% CI 0.05-0.13) were factors associated with condomless sex with casual partners in the last sex episode. Males (AOR 3.03, 95% CI 1.96-4.69 and AOR 2.19, 95% CI 1.33-3.60), local workers (AOR 2.11, 95% CI 1.01-4.42 and AOR 3.42, 95% CI 1.63-7.21), being single (AOR 2.04, 95% CI 1.39-3.01 and AOR 2.49, 95% CI 1.61-3.87), having sexual debut aged Conclusions : Sexual risk behaviours were prevalent despite most participants having basic HIV/AIDS knowledge. Future workplace-based prevention programs should target factory workers and there should be a focus on enhanced sexual education to reduce HIV transmission in China.

The association between entrapment and depression among migrant workers in China: a social rank theory based study.

BACKGROUND: Migrant workers are a group susceptible for depression evolution due to occupational maladaptive triggers. The social rank theory illustrates the pathology process from defensive adaptation to depression, pointing out the early prevention of depression by discovering entrapment. This study aims to reveal the relationship between migrant workers' entrapment and depressive symptoms. METHODS: A total of 1805 migrant workers in Shenzhen were recruited by stratified multi-stage sampling. Sample's demographic, behavioral and psychosocial characteristics were described and analyzed to reveal the relationship between entrapment and depressive symptoms. The Receiver Operator Characteristic was performed to find the optimal cut-off point of Entrapment Scale for predicting depressive symptoms. RESULTS: In the binary logistic regression of sociodemographic variables, migrant workers who were married (univariate odds ratio (ORu) = 0.69, 95% Confidence Interval (CI) = 0.56-0.84), owned 1 or 2 children (ORu = 0.71, 95% CI = 0.58-0.86), had been working over 10 years (ORu = 0.71, 95% CI = 0.54-0.95), earned > 4999 yuan per month (ORu = 0.68, 95% CI = 0.47-0.99; multivariate odds ratio (ORm) = 0.57, 95% CI = 0.38-0.87) or with low risks of alcohol use disorders (ORu = 0.51, 95% CI = 0.34-0.75) had lower risks of depressive symptoms. After adjusted the aforementioned significant sociodemographic variables, migrant workers with severer entrapment were more likely to have depressive symptoms (adjusted odds ratio (ORa) = 1.13, 95% CI = 1.12-1.15). Besides, the study proved the reliability and validity of the Chinese version Entrapment Scale, preferring a two-dimensional structure, and 11 was the optimal cut-off value of this scale for predicting depressive symptoms among migrant workers. CONCLUSIONS: This result indicates the potential value of entrapment according to the social rank theory on facilitating early prevention of migrant works' depression and the application value of Entrapment Scale for effectively measuring mental status among migrant workers.

Patient Activeness During Online Medical Consultation in China: Multilevel Analysis.

BACKGROUND: Online medical consultation is an important complementary approach to offline health care services. It not only increases patients' accessibility to medical care, but also encourages patients to actively participate in consultation, which can result in higher shared decision making, patient satisfaction, and treatment adherence. OBJECTIVE: This study aims to explore multilevel factors that influence patient activeness in online medical consultations. METHODS: A data set comprising 40,505 patients from 300 physicians in 10 specialties was included for multilevel analysis. Patient activeness score (PAS) was calculated based on the frequency and the proportion of patient discourses to the total frequency of doctor-patient interactions. Intraclass correlation coefficients were calculated to identify between-group variations, and the final multilevel regression model included patient- and physician-level factors. RESULTS: Patients were not equally active in online medical consultations, with PASs varying from 0 to 125.73. Patient characteristics, consultation behavioral attributes, and physician professional characteristics constitute 3 dimensions that are associated with patient activeness. Specifically, young and female patients participated more actively. Patients' waiting times online (ß=-.17; P<.001) for physician responses were negatively correlated with activeness, whereas patients' initiation of conversation (ß=.83; P<.001) and patient consultation cost (ß=.52; P<.001) in online medical consultation were positively correlated. Physicians' online consultation volumes (ß=-.10; P=.01) were negatively associated with patient activeness, whereas physician online consultation fee (ß=.03; P=.01) was positively associated. The interaction effects between patient- and physician-level factors were also identified. CONCLUSIONS: Patient activeness in online medical consultation requires more scholarly attention. Patient activeness is likely to be enhanced by reducing patients' waiting times and encouraging patients' initiation of conversation in online medical consultation. The findings have practical implications for patient-centered care and the improvement of online medical consultation services.

Exploring subtypes and correlates of internet gaming disorder severity among adolescents during COVID-19 in China: A latent class analysis.

The WHO recently included Gaming Disorder as a psychiatric diagnosis. Whether there are distinct groups of adolescents who differ based on severity of gaming disorder and their relationships with other mental health and addictive behavior outcomes, including problematic smartphone use (PSU), remains unclear. The current study explored and identified subtypes of Internet Gaming Disorder (IGD) severity and estimated the association between these subtypes and other disorders. Participants completed online questionnaires assessing the severity of IGD, PSU, depression, and anxiety during COVID-19. We conducted a latent class analysis of IGD symptoms among 1,305 Chinese adolescents (mean age = 15.2; male = 58.5%) from 11 secondary schools in Macao (SAR), China. Multinomial logistic regression estimated correlates of latent class membership and PSU. A 4-class model adequately described the sample subgroups. Classes were labeled as normative gamers (30.9%), occasional gamers (42.4%), problematic gamers (22.7%), and addictive gamers (4.1%). Relative to normative gamers, PSU severity, depression, and being male were significantly higher among problematic gamers, addictive gamers, and occasional gamers. Only problematic gamers showed significant positive associations with anxiety severity compared to the other groups. The study revealed the differences in severity of gaming disorder and its association with psychopathology outcomes. Application in screening for IGD and comorbidity is discussed. Supplementary Information: The online version contains supplementary material available at 10.1007/s12144-022-03133-8.

Moderating effect of people-oriented public health services on depression among people under mandatory social isolation during the COVID-19 pandemic: a cross-sectional study in China.

BACKGROUND: Public health measures, such as social isolation, are vital to control the spread of the coronavirus disease 2019 (COVID-19), but such measures may increase the risk of depression. Thus, this study examines the influencing and moderating factors of depressive symptoms among individuals subjected to mandatory social isolation. METHODS: An online cross-sectional survey was conducted to collect data from people under mandatory home or centralized social isolation in Shenzhen, China, from February 28 to March 6, 2020. The perceived risk of infection with COVID-19, perceived tone of media coverage, perceived quality of people-oriented public health services, and their depressive symptoms were assessed. Three rounds of stepwise multiple regression were performed to examine the moderating effects after controlling various variables, such as demographics, duration and venue of mandatory social isolation, infection and isolation status of family, time spent on COVID-related news, and online social support. RESULTS: Among the 340 participants, 57.6% were men, the average age was 35.5 years old (SD = 8.37), and 55.6% held a bachelor's degree or above. Individuals subjected to mandatory social isolation generally reported low levels of depressive symptoms. Perceived susceptibility to infection was relatively low, whereas perceived tone of media coverage was mainly positive. In terms of perceived quality of public health services, 12 (3.5%), 103 (30.3%), and 225 (66.2%) participants reported low, medium, and high quality of people-oriented services, respectively. Perceived susceptibility was positively associated with depression, whereas perceived tone of media coverage was negatively associated. The quality of people-centered public health services moderated the association between perceived risk and depressive symptoms and between perceived tone of media coverage and depressive symptoms. CONCLUSIONS: This study revealed the depressive symptoms among individuals subjected to mandatory social isolation during the COVID-19 pandemic and highlighted that frontline public health workers play a critical role in protecting public mental health.

Turn to the Internet First? Using Online Medical Behavioral Data to Forecast COVID-19 Epidemic Trend.

The surveillance and forecast of newly confirmed cases are important to mobilize medical resources and facilitate policymaking during a public health emergency. Digital surveillance using data available online has increasingly become a trend with the advancement of the Internet. In this study, we assessed the predictive value of multiple online medical behavioral data, including online medical consultation (OMC), online medical appointment (OMA), and online medical search (OMS) for the regional outbreak of coronavirus disease 2019 in Shenzhen, China during January 1, 2020 to March 5, 2020. Multivariate vector autoregression models were used for the prediction. The results identified a novel predictor, OMC, which can forecast the disease trend up to 2 days ahead of the official reports of confirmed cases from the local health department. OMS data had relatively weaker predictive power than OMC in our model, and OMA data failed to predict the confirmed cases. This study highlights the importance of OMC data and has implication in providing evidence-based guidelines for local authorities to evaluate risks and allocate resources during the pandemic.

Open eyes and closed eyes elicit different temporal properties of brain functional networks.

The eyes are our windows to the brain. There are differences in brain activity between people who have their eyes closed (EC) and eyes open (EO). Previous studies focused on differences in brain functional properties between these eyes conditions based on an assumption that brain activity is a static phenomenon. However, the dynamic nature of the brain activity in different eyes conditions is still unclear. In this study, we collected resting-state fMRI data from 21 healthy subjects in the EC and EO conditions. Using a sliding time window approach and a k-means clustering algorithm, we calculated the temporal properties of dynamic functional connectivity (dFC) states in the eyes conditions. We also used graph theory to estimate the dynamic topological properties of functional networks in the two conditions. We detected two dFC states, a hyper-connected State 1 and a hypo-connected State 2. We showed the following results: (i) subjects in the EC condition stayed longer in the hyper-connected State 1 than those in the EO; (ii) subjects in the EO condition stayed longer in the hypo-connected State 2 than those in the EC; and (iii) the dFC state transformed into the other state more frequently during EC than during EO. We also found the variance of the characteristic path length was higher during EC than during EO in the hyper-connected State 1. These results indicate that brain activity may be more active and unstable during EC than during EO. Our findings may provide insights into the dynamic nature of the resting-state brain and could be a useful reference for future rs-fMRI studies.

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.

Leveraging Crowdsourcing for Human Immunodeficiency Virus Testing Posters: A Visual Content Analysis and Cognitive Responses Among Chinese Men Who Have Sex With Men.

INTRODUCTION: Extensive marketing and advertising research has informed a deep understanding of the link between visual design and consumer behaviors, providing a useful framework for assessing associations between human immunodeficiency virus (HIV)-related health posters and viewer responses. METHODS: Crowdsourced posters included finalist submissions from a series of nationwide crowdsourcing contests. Centers for Disease Control (CDC) images were sampled from an online poster database maintained by the National Center for acquired immune deficiency syndrome (AIDS). Once coded according to a set of 27 visual features, posters were shown to an online sample of Chinese men who have sex with men-a group currently experiencing the highest HIV incidence in China-to assess their viewer response. RESULTS: The CDC posters were more likely to use positive facial expressions (65%; 95% confidence interval [CI], 40.9-83.7] vs 12.5%; 95% CI, 2.2-4%) and an educational messaging style (85%; 95% CI, 61.1-96% vs 31.3%; 95% CI, 12.1-58.5). Crowdsourced posters exhibited better craftsmanship than CDC posters (more design simplicity, image diversity, color choice, design quality, and moderate use of text) used more visual metaphors (56.3%; 95% CI, 30.6-79.2 vs 5%; [95% CI, 0.2-26.9%]). Several differences in visual complexity were identified but these lacked statistical significance. CONCLUSION: Crowdsourced posters were of higher craftsmanship, possibly due to their ability to recruit skills of professional designers. The CDC posters' use of positive visual reinforcement (smiling faces) and educational messaging may be a legacy of their role in the early days of the epidemic in disseminating basic HIV/AIDS knowledge and dispelling misinformation. Crowdsourcing posters' used more metaphors, suggesting better ability to leverage in-group codes and language.

Anticipated HIV stigma among HIV negative men who have sex with men in China: a cross-sectional study.

BACKGROUND: Anticipated HIV stigma, i.e., the expectation of adverse experiences from one's seroconversion, is associated with both negative psychological and behavioral outcomes. We know little about anticipated HIV stigma's relationship with emerging technologies, such as HIV self-testing (HIVST) and online sex-seeking platforms, that have become popular among populations that are disproportionately affected by HIV/AIDS. This study examined correlates of anticipated HIV stigma among Chinese men who have sex with men (MSM). METHODS: In July 2016, MSM, who were ≥ 16 years old and self-reported as HIV negative or unknown, were recruited from a gay mobile phone application in China. Information regarding socio-demographics, sexual behaviors, sexual health service utilization, and anticipated HIV stigma were collected. Anticipated HIV stigma (i.e., negative attitude toward future stigmatization of HIV seroconversion by others) was measured as the mean score from a 7-item Likert-scale ranging from 1 (low) to 4 (high). Generalized linear models were conducted to examine the factors associated with the anticipated HIV stigma scores. RESULTS: Overall, 2006 men completed the survey. Most men completed high school (1308/2006, 65.2%) and had an annual personal income of ≤9200 USD (1431/2006, 71.3%). The mean anticipated HIV stigma score for the participants was 2.98 ± 0.64. Using social media to seek sexual partners was associated with higher anticipated HIV stigma (Adjusted ß = 0.11, 95% confidence interval (CI): 0.05 to 0.17, p = 0.001). HIV self-testing (Adjusted ß = - 0.07, 95%CI: - 0.13 to - 0.01, p = 0.02) and having disclosed one's sexual orientation to a healthcare provider (Adjusted ß = - 0.16, 95%CI: - 0.22 to - 0.96, p < 0.001) were associated with lower anticipated HIV stigma. CONCLUSION: Our data suggested that anticipated HIV stigma is still common among Chinese MSM not living with HIV. Tailored anti-HIV stigma campaigns on social media are especially needed, and the promotion of HIVST may be a promising approach.

Efficacy of HIV interventions among factory workers in low- and middle-income countries: a systematic review.

BACKGROUND: Factory workers in low- and middle-income countries (LMICs) are vulnerable to HIV transmission. Interventions are needed to prevent HIV in this population. We systematically reviewed published literature on the efficacy of various HIV interventions in reducing stigma, risk behaviors and HIV transmission among factory workers. METHODS: A systematic review was performed using predefined inclusion and exclusion criteria. Four databases (PubMed, PsycINFO, Scopus and EMBASE) were searched for relevant publications between January 1, 1990 and December 31, 2018. Two independent reviewers assessed the methodological quality of studies. RESULTS: Thirteen articles were included, with 2 randomized controlled trials and 11 cohort studies. Five interventions and their combinations were summarized. Educational intervention increased condom use and reduced the use of recreational drugs and alcohol before sex. Community intervention that proactively provide HIV counselling and testing (HCT) services could increase the detection rate of HIV and other sexually transmitted diseases (STDs). Lottery intervention increased HCT uptake and decreased HIV public stigma. Education combined with community intervention reduced the proportion of workers with casual sex and enhanced HIV knowledge. Peer education combined with community intervention increased the proportion of workers who were willing to take their partners to HCT. Policy intervention combined with peer education enhanced HIV knowledge, perceived condom accessibility and condom use with regular partners. CONCLUSIONS: Various interventions improved HIV knowledge, decreased HIV stigma and reduced HIV-related risk behaviors among factory workers in LMICs. The combination of multiple interventions tended to achieve better efficacy than a single intervention. Persistent combination interventions are essential to address HIV in this population.

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.

MSM Behavior Disclosure Networks and HIV Testing: An Egocentric Network Analysis Among MSM in China.

Men who have sex with men (MSM) disclose same-sex behaviors with others, creating disclosure networks. This study examined the characteristics of disclosure networks that are associated with HIV testing among MSM in China through an online nationwide survey. Name-generator questions were used to ask each participant ("ego") to nominate up to five social network members ("alters") with whom he had disclosed same-sex behaviors. Among the 806 men, the average disclosure network size was 4.05. MSM who reported larger disclosure networks were more likely to have been tested for HIV (aOR 1.21, 95% CI 1.08-1.34). The most common disclosure network alters were friends (45.1%), followed by sex partners (18.7%) and healthcare professionals (2.5%). Men who disclosed to healthcare professionals were more likely to test for HIV compared to men who disclosed to family members (aOR 5.43, 95% CI 2.11-14.04). Our findings can inform disclosure network-based interventions to promote MSM HIV testing.

Recalling, Sharing and Participating in a Social Media Intervention Promoting HIV Testing: A Longitudinal Analysis of HIV Testing Among MSM in China.

Social media interventions may enhance HIV services among key populations, including men who have sex with men (MSM). This longitudinal analysis examined the effect of recalling, sharing, and participating in different components of a social media intervention on HIV testing among MSM. The social media intervention included six images/texts and information about an online local community contest to promote testing. Of the 1033 men, they recalled a mean of 2.7 out of six images and shared an average of one image online. 34.5% of men recalled information on the online local community contest and engaged in a mean of 1.3 contest. Recalling images/texts (aOR = 1.13, 95% CI 1.02-1.25) and recalling a local contest (aOR = 1.59, 95% CI 1.13-1.24) were associated with facility-based HIV testing. This study has implications for the development and evaluation of social media interventions to promote HIV testing.

What happens after HIV self-testing? Results from a longitudinal cohort of Chinese men who have sex with men.

BACKGROUND: HIV self-testing (HIVST) is a promising approach to expand HIV testing. HIVST is a process in which a person performs an HIV test and interprets the result. Negative HIVST results may encourage men who have sex with men (MSM) to use HIV prevention services. The objective of this study was to examine behaviors (e.g., facility-based HIV testing, condom use) after a negative HIVST test result among Chinese MSM. METHODS: We collected data from MSM in eight Chinese cities over a 12-month period. This is a secondary analysis of longitudinal cohort data collected as part of an intervention trial to increase HIV testing. Men completed a survey that described sociodemographic information, sexual behaviors, HIV self-testing, and facility-based HIV testing. Men who completed at least one follow-up survey were included in this analysis. Generalized linear mixed models were used to evaluate whether HIVST increased subsequent facility-based HIV testing and consistent condom use. RESULTS: We included 1219 men. Most men (78.7%) were under 30 years old and had never been married (87.0%). 755 (61.9%) men tested for HIV and 593 (49.3%) men self-tested during the study period. At baseline, among men who had never been tested for HIV, 44.9% (314/699) initiated HIVST during the study period. HIVST was associated with subsequent facility-based testing (aOR of 1.87, 95% CI: 1.47-2.37). HIVST was also associated with subsequent consistent condom use (aOR = 1.53, 95% CI: 1.13-2.06). CONCLUSION: HIVST was associated with subsequent facility-based HIV testing and consistent condom use. HIVST may enhance uptake of related HIV prevention services at facilities, suggesting the need for more implementation research.

Leading by Example: Web-Based Sexual Health Influencers Among Men Who Have Sex With Men Have Higher HIV and Syphilis Testing Rates in China.

BACKGROUND: The spread of healthy behaviors through social networks may be accelerated by influential individuals. Previous studies have used lay health influencers to prevent sexually transmitted infections (STIs) among internet-using men who have sex with men (MSM). However, there is a lack of understanding of the characteristics of this key subset of MSM. OBJECTIVE: This study aimed to examine sociodemographic characteristics, HIV and syphilis testing, and sexual behaviors of Web-based MSM sexual health influencers (SHIs) in China, defined as individuals with relatively stronger influence on spreading HIV and STI information online. METHODS: A Web-based survey of MSM was conducted in August 2017 as a final follow-up of a randomized controlled trial promoting HIV testing in 8 Chinese cities. Men were recruited through a gay social networking mobile phone app and were included if they were born biologically male, aged 16 years and above, ever had sex with another man, and HIV negative or with unknown HIV status. Information regarding sociodemographic characteristics, sexual behaviors, and HIV and syphilis testing was obtained. We assessed men's Web-based sexual health influence using a standardized 6-item opinion leadership scale focused on HIV and STI information. Influencers were defined as those whose mean score ranked within the top 13% (a higher score means greater influence). We used multivariable linear and logistic regression models to measure Web-based sexual health influence's association with HIV and syphilis testing, controlling for intervention trial effects, age, education, income, and marital status. RESULTS: Overall, 1031 men completed the survey. Most men were younger than 30 years (819/1031, 79.43%) and had at least college education (667/1031, 64.69%). Influencers were more likely to get tested for HIV (73/132, 55.3% vs 337/899, 37.5%; P<.001) and syphilis (35/132, 26.5% vs 137/899, 15.2%; P=.001) in the last 3 months compared with noninfluencers. There were no significant differences in condomless sex with male partners (26/132, 19.7% vs 203/899, 22.6%; P=.46), mean number of male sex partners (1.32 vs 1.11; P=.16) in the last 3 months, and mainly meeting male sex partners online in the last 12 months (97/132, 73.5% vs 669/899, 74.4%; P=.82) between influencers and noninfluencers. Regression analyses showed that influencers had higher odds of HIV testing (adjusted odds ratio, AOR 2.16, 95% CI 1.48-3.17) and syphilis testing (AOR 1.99, 95% CI 1.28-3.10) in the last 3 months. CONCLUSIONS: We identified Web-based SHIs who might be more likely to help promote healthy HIV and syphilis testing behaviors through MSM populations. Leveraging existing influencers may help improve HIV and syphilis testing among their networks.

Providing competent, comprehensive and inclusive sexual health services for men who have sex with men in low- and middle-income countries: a scoping review.

Although men who have sex with men (MSM) are disproportionately affected by HIV and other sexually transmissible infections, sexual health services for MSM in low- and middle-income countries (LMIC) remain under-resourced and are poorly understood. A scoping review of literature on MSM sexual health in LMIC was conducted in order to identify key clinical services and gaps in knowledge. Three databases were searched, in addition to hand-reviewing key journals and bulletins, to identify literature with a focus on MSM sexual health. Key services related to providing care to MSM in LMIC that emerged from our review are described. These services include creation of safe and confidential clinic environments, HIV testing services, behavioural interventions, HIV pre-exposure prophylaxis (PrEP), rapid antiretroviral therapy (ART) initiation and STI services. Compared with high-income settings, major differences in LMIC include lack of diagnostic technology, unfavourable legal environments and lack of funding for MSM health. Innovative approaches to healthcare delivery, such as harnessing mobile technology, self-testing and crowdsourcing interventions, can improve health services among MSM in LMIC. There are gaps in the evidence about how best to provide sexual health services for MSM in LMIC settings. Implementation research and scale-up of existing biomedical and behavioural interventions, such as HIV/STI testing services, PrEP and early antiretroviral initiation are urgently needed in LMIC.

Crowdsourcing to expand HIV testing among men who have sex with men in China: A closed cohort stepped wedge cluster randomized controlled trial.

BACKGROUND: HIV testing rates are suboptimal among at-risk men. Crowdsourcing may be a useful tool for designing innovative, community-based HIV testing strategies to increase HIV testing. The purpose of this study was to use a stepped wedge cluster randomized controlled trial (RCT) to evaluate the effect of a crowdsourced HIV intervention on HIV testing uptake among men who have sex with men (MSM) in eight Chinese cities. METHODS AND FINDINGS: An HIV testing intervention was developed through a national image contest, a regional strategy designathon, and local message contests. The final intervention included a multimedia HIV testing campaign, an online HIV testing service, and local testing promotion campaigns tailored for MSM. This intervention was evaluated using a closed cohort stepped wedge cluster RCT in eight Chinese cities (Guangzhou, Shenzhen, Zhuhai, and Jiangmen in Guangdong province; Jinan, Qingdao, Yantai, and Jining in Shandong province) from August 2016 to August 2017. MSM were recruited through Blued, a social networking mobile application for MSM, from July 29 to August 21 of 2016. The primary outcome was self-reported HIV testing in the past 3 months. Secondary outcomes included HIV self-testing, facility-based HIV testing, condom use, and syphilis testing. Generalized linear mixed models (GLMMs) were used to analyze primary and secondary outcomes. We enrolled a total of 1,381 MSM. Most were ≤30 years old (82%), unmarried (86%), and had a college degree or higher (65%). The proportion of individuals receiving an HIV test during the intervention periods within a city was 8.9% (95% confidence interval [CI] 2.2-15.5) greater than during the control periods. In addition, the intention-to-treat analysis showed a higher probability of receiving an HIV test during the intervention periods as compared to the control periods (estimated risk ratio [RR] = 1.43, 95% CI 1.19-1.73). The intervention also increased HIV self-testing (RR = 1.89, 95% CI 1.50-2.38). There was no effect on facility-based HIV testing (RR = 1.00, 95% CI 0.79-1.26), condom use (RR = 1.00, 95% CI 0.86-1.17), or syphilis testing (RR = 0.92, 95% CI 0.70-1.21). A total of 48.6% (593/1,219) of participants reported that they received HIV self-testing. Among men who received two HIV tests, 32 individuals seroconverted during the 1-year study period. Study limitations include the use of self-reported HIV testing data among a subset of men and non-completion of the final survey by 23% of participants. Our study population was a young online group in urban China and the relevance of our findings to other populations will require further investigation. CONCLUSIONS: In this setting, crowdsourcing was effective for developing and strengthening community-based HIV testing services for MSM. Crowdsourced interventions may be an important tool for the scale-up of HIV testing services among MSM in low- and middle-income countries (LMIC). TRIAL REGISTRATION: ClinicalTrials.gov NCT02796963.
