Social media and secondary distribution (distributing self-testing kits by indexes through their networks) both show strong promise to improve human immunodeficiency virus (HIV) uptake. We assessed an implementation program in Zhuhai, China, which focused on the of HIV/syphilis self-test among men who have sex with (MSM) via social media.
Background Digital network–based methods may enhance peer distribution of HIV self-testing (HIVST) kits, but interventions that can optimize this approach are needed. We aimed to assess whether monetary incentives and referral could improve a secondary program for HIVST among men who have sex with (MSM) in China. Methods findings Between October 21, 2019 September 14, 2020, 3-arm randomized controlled, single-blinded trial was conducted online 309 individuals (defined as index participants)...
Human immunodeficiency virus (HIV) testing is a crucial strategy for HIV prevention. rates remain low among men who have sex with (MSM) in China. Digital network-based secondary distribution considered as an effective model to enhance self-testing (HIVST) key populations. platforms provide opportunities testers apply HIVST kits by themselves, and allows them multiple deliver their sexual partners or members within social network. We describe three-arm randomized controlled trial examine the...
Background Social network–based strategies can expand HIV/syphilis self-tests among men who have sex with (MSM). Sexual health influencers are individuals particularly capable of spreading information about HIV and other sexually transmitted infections (STIs) within their social networks. However, it remains unknown whether a sexual influencer encourage peers to self-test for HIV/syphilis. Objective The aims this study were examine the impact MSM on improving uptake networks compared that...
Background Men who have sex with men (MSM) face significant risks of Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (NG) infection. Nevertheless, only limited studies looked into the site-specific infection and clearance CT/NG. In order to prevent transmission, it is essential understand underlying factors that drive spontaneous clearance. Methods A 12-week cohort study examined association between CT/NG infection, self-clearance, sexual behaviors among MSM. The Willingness Service...
Abstract Background Understanding factors associated with antiretroviral treatment (ART) adherence is crucial for ART success among people living HIV (PLHIV) in the “test and treat” era. Multiple psychosocial tend to coexist have a syndemic effect on adherence. We aimed explore of multiple PLHIV newly starting Guangdong Province, China. Methods Newly diagnosed from six cities Province were recruited between May 2018 June 2019, then followed up 2019 August 2020. Baseline follow-up data...
Background HIV self-testing (HIVST) has been rapidly scaled up and additional strategies further expand testing uptake. Secondary distribution involves people (defined as “indexes”) applying for multiple kits subsequently sharing them with “alters”) in their social networks. However, identifying key influencers is difficult. Objective This study aimed to develop an innovative ensemble machine learning approach identify among Chinese men who have sex (MSM) secondary of HIVST kits. Methods We...
Background: Solidarity, such as community connectedness and social cohesion, may be useful in improving HIV testing uptake among men who have sex with (MSM). This study aimed to evaluate the impact of solidarity on before coronavirus disease 2019 (COVID-19) willingness during COVID-19 MSM China. Materials Methods: An online survey was conducted collect sociodemographic, sexual behavioral, items' information from participants. We first used factor analysis reveal principal component items...
Abstract Background Condom use at last intercourse is an effective indicator for human immunodeficiency virus (HIV) prevention. To identify at-risk individuals and improve prevention strategies, this study explored factors associated with condomless sex in the year developed a risk estimation model to calculate individual possibility of among college students Zhuhai, China. Methods A cross-sectional was conducted 1430 who had from six universities Zhuhai. The least absolute shrinkage...
Abstract Background HIV self-testing (HIVST), especially the secondary distribution of HIVST (SD-HIVST) initiated by sexual health influencers (SHIs), has been recognized as an effective strategy in promoting testing, among men who have sex with (MSM). This quasi-experimental study aimed to evaluate whether SHIs identified through ensemble machine learning approach can distribute more than those empiricalscale. Methods We will recruit eligible adults (≥18 years old) were assigned male gender...

Human immunodeficiency virus self-testing (HIVST) is an innovative and effective strategy important to the expansion of HIV testing coverage. Several implementations HIVST have been developed piloted among some high-risk populations like men who sex with (MSM) meet global target. One secondary distribution HIVST, in which individuals (defined as indexes) were given multiple kits for both self-use (i.e.self-testing) other people their MSM social network alters). Studies about mainly...
Abstract Background HIV self-testing (HIVST) has been rapidly scaled up and additional strategies further expand testing uptake. Secondary distribution people (indexes) apply for multiple kits pass these to (alters) in their social networks. However, identifying key influencers is difficult. This study aimed develop an innovative ensemble machine learning approach identify among Chinese men who have sex with (MSM) HIVST secondary distribution. Method We defined three types of influencers: 1)...
Background HIV self-testing (HIVST) is effective in improving the uptake of testing among key populations. Complementary data on economic evaluation HIVST critical for planning and scaling up HIVST. This study aimed to evaluate cost a community-based organisation (CBO)-led model implemented China. Methods An was conducted by comparing CBO-led with facility-based rapid diagnostics (HIV-RDT) model. The full cost, including fixed variable from health provider perspective using micro costing...
Abstract Background Sexual behavior drives the transmission of sexually transmitted infections, especially among men who have sex with (MSM). This study aims to evaluate sexual changed MSM during COVID-19. Methods An online survey was conducted collect socio-demographic, behavioral, and HIV testing information before Chi-square used determine differences We identified factors associated using logistic regression. Results Totally 506 participated in survey. Compared participants didn't reduce...
Background: Digital network-based methods may enhance peer distribution of HIV self-testing (HIVST) kits, but implementation research is needed to optimize this approach. We aimed assess whether monetary incentives and referral could improve a secondary program for HIVST among men who have sex with (MSM) in China.Method: A three-arm randomized controlled trial was conducted Guangdong Province, China. Individuals were born biologically as males, aged 18 years or older, ever had male-to-male...
Secondary distribution of HIV self-test is promising to increase testing uptake while the facilitators and barriers secondary remain unclear. In-depth interviews were conducted with 22 MSM who had participated in HIVST southern China. Data thematically analyzed capture participants' motivations, procedures, challenges when accessing distributing self-tests. China are willing distribute members their social network, but decision-making impacted by ability broach sexual health conversations,...
To assess whether HIV self-testing (HIVST) has a better performance in identifying HIV-infected cases than the facility-based testing (HIVFBT) approach. A cross-sectional study was conducted among men who have sex with (MSM) by using an online questionnaire (including information on sociodemographic, sexual biography, and history) blood samples (for limiting antigen avidity enzyme immunoassay, gene subtype testing, taking confirmed test). MSM were firstly identified as positive through HIVST...
