Background
Secondary distribution of human immunodeficiency virus (HIV) self-testing (HIVST) kits offers a promising strategy to expand testing among marginalized men who have sex with men (MSM). We compared characteristics of kit distributors (index participants) and recipients, and identified predictors of HIV testing and kit distribution.
Methods
We analyzed data from a randomized controlled trial among MSM in Zhuhai, China (2019–2020). Regression models identified predictors of HIV testing and kit distribution.
Results
A total of 303 index participants and 264 recipients were included. Index participants were more likely than recipients to have previously tested for HIV (84.5% vs 62.5%), report recent (past 3 months) male-male anal intercourse (83.2% vs 60.6%), and have multiple male partners (52.8% vs 40.6%). Among index participants, HIV testing was associated with older age (per year increase: adjusted odds ratio [aOR], 1.14; 95% confidence interval [CI], 1.05–1.24), higher education (college vs high school or below: aOR, 4.71; 95% CI, 1.94–11.6), and condomless sex (aOR, 3.90; 95% CI, 1.37–12.9). Among recipients, higher income ($451–750: aOR, 2.58; 95% CI, 1.11–6.00; $751–1200; aOR, 2.35; 95% CI, 1.04–5.36, vs
