Area of Science:

  • Public Health
  • Social Psychology
  • Health Communication

Background:

  • Stigma against individuals with hepatitis B virus (HBV) presents a significant obstacle to effective prevention, diagnosis, and treatment in China.
  • Men who have sex with men (MSM) are a key population disproportionately affected by HBV and often face heightened stigma.

Purpose of the Study:

  • To evaluate the effectiveness of an innovative intervention using crowdsourced media in reducing HBV stigma among MSM in China.
  • To identify factors associated with HBV stigma within this population.

Main Methods:

  • A randomized controlled trial was conducted with 470 MSM in China.
  • Participants were exposed to crowdsourced images and videos designed to promote HBV testing and reduce stigma.
  • HBV stigma was measured using a 20-item scale at baseline and four weeks post-intervention, with data analyzed via linear regression.

Main Results:

  • Full exposure to the crowdsourced intervention was significantly associated with a reduction in HBV stigma (adjusted beta = -3.49, P = .01).
  • Partial exposure did not yield statistically significant stigma reduction.
  • Higher baseline stigma was linked to not having a recent doctor's visit (adjusted beta = 4.35, P = .04), with stigma most pronounced regarding physical contact.

Conclusions:

  • Crowdsourcing is an effective strategy for decreasing HBV stigma in vulnerable populations like MSM in China.
  • This approach holds potential for broader application in anti-stigma campaigns within low- and middle-income countries.
