Article Synopsis
  • The study addresses the growing public health issue of herpes simplex type 2 (HSV-2) infections in China, highlighting the need for better intervention strategies based on epidemiological data.
  • A systematic review of 23,999 articles resulted in 402 publications being analyzed, revealing a general HSV-2 seroprevalence of 7.7%, with higher rates among intermediate-risk (14.8%) and key populations (31.7%), particularly among female sexual workers.
  • Findings indicate significant regional disparities in HSV-2 prevalence, with northeastern China having higher rates, and a notable difference in prevalence estimates between Chinese and English publications among key populations.

Background: This study aimed to assess the acceptability, feasibility, and preliminary effectiveness of a crowdsourced HIV partner services (PS) intervention among men who have sex with men living with HIV (MLWH) in China.

Methods: A pilot 2-arm randomized controlled trial was conducted in 3 HIV testing clinics in China. The control arm received conventional HIV PS, whereas the intervention arm received a crowdsourced intervention, including HIV self-testing kits for secondary distribution (HIVST-SD), digital education materials, and assisted PS.

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.

Background: Research on the health and economic costs due to insufficient sleep remains scant in developing countries. In this study we aimed to estimate the years of life lost (YLLs) due to short sleep and quantify its economic burden in China.

Methods: We estimated both individual and aggregate YLLs due to short sleep (ie, ≤6 hours) among Chinese adults aged 20 years or older by sex and five-year age groups in 2010, 2014, and 2018.

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.

Introduction: A Chinese clinical trial has demonstrated that a prosocial pay-it-forward intervention that offered subsidized vaccination and postcard messages effectively increased influenza vaccine uptake and vaccine confidence. This secondary analysis explored the potential mediating role of vaccine confidence on the association between a pay-it-forward intervention and influenza vaccine uptake, and how this might vary by individual annual income levels.

Methods: Data from 300 participants (150 standard-of-care and 150 pay-it-forward participants) were included in the analysis.

Objectives: We provide a guide to conducting a crowdsourcing activity at an international sexually transmitted infection (STI) conference to design public messaging about STI testing and disseminating that messaging via social media.

Methods: A speaker gave a presentation at a conference plenary session on the concepts of cocreation, crowdsourcing and designathons, and the application of these participatory approaches in public health research. To illustrate one of these approaches (crowdsourcing), attendees in the audience were asked to take part in a voluntary participatory activity, in which they would pair up with a fellow attendee sitting nearby and write down an idea on a blank notecard.

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 and subsequently sharing them with people (defined as "alters") in their social networks. However, identifying key influencers is difficult.

Background: People living with HIV(PLWH) are deemed more vulnerable to the SARS-CoV-2 infection than the uninfected population. Vaccination is an effective measure for COVID-19 control, yet, little knowledge exists about the willingness of men who have sex with men (MSM) living with HIV in China to be vaccinated.

Methods: This cross-sectional study evaluated the willingness of MSM living with HIV to receive COVID-19 vaccination in six cities of Guangdong, China, from July to September 2020.

Objectives: Despite a high risk of human papillomavirus (HPV) infection among men who have sex with men (MSM), few have ever tested. This study aimed to evaluate the feasibility and accuracy of HPV self-sampling among Chinese MSM, with the purpose of measuring the feasibility of self-sampling as an alternative in HPV testing scenarios.

Methods: Eligible participants were those who were assigned male at birth, aged 18 or above, had sex with men in the past year and had never gotten HPV vaccine.

Background: HIV partner notification services (HIV PS) have been poorly implemented in most low- and middle-income countries, including China. Understanding the social context of partner services for key populations is important for scaling up HIV testing services. This study aims to examine facilitators and barriers of HIV PS using qualitative analysis.
