Hepatitis C Clinical Trial
Official title:
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
This is an online randomized controlled trial (RCT) comparing men who have sex with men (MSM) exposed to a crowdsourced intervention to MSM who did not receive the intervention to determine the effect on Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) testing. Participants will be randomly assigned in a 1:1 ratio to intervention or control using a computer-based allocation system. Participants will be assessed for primary and secondary outcomes four weeks after randomization.
700 MSM will be recruited through social media operated by gay organizations in China. Eligible participants will be born biologically male, age 16 years or older, report previous anal sex with another man, and reside in China. Men self-reporting previous HBV vaccination, HBV testing, or HCV testing will be excluded. After completing a baseline online survey, participants will be randomly assigned to intervention or control arms with a 1:1 allocation ratio. The intervention will include two components: (1) a multimedia component will deliver two videos and two images promoting HBV and HCV testing developed through a crowdsourcing contest in China. (2) A participatory component will invite men to submit suggestions for how to improve crowdsourced videos and images. The control arm will not view any images or videos and will not be invited to submit suggestions. All participants will be offered reimbursement for HBV and HCV testing costs. The primary outcome is HBV and HCV test uptake confirmed through electronic submission of test report photos within four weeks of enrollment. Secondary outcomes include self-reported HBV and HCV test uptake, HBV vaccination uptake, and change in stigma toward people living with HBV measured through a follow-up survey after four weeks. Men with primary and secondary outcomes will be calculated using intention to treat and as-exposed analyses and compared using two-sided 95% confidence intervals. ;
