Background: Regular testing for hepatitis C virus (HCV) provides an opportunity for HCV prevention and treatment efforts. In Thailand, the barriers and facilitators of HCV testing among people who inject drugs (IDU) are not known.
Methods: Using data derived from the Mitsampan Community Research Project between July and October 2011, we assessed the prevalence and factors associated with ever having been tested for HCV antibodies using bivariate statistics and multivariate logistic regression.
Results: Among 427 participants, 141 (33.0%) reported a history of HCV antibody testing. In multivariate analyses, factors positively associated with receiving an HCV antibody test included higher than secondary education [adjusted odds ratio (AOR) = 2.20; 95% confidence interval (CI): 1.35-3.64], binge drug use (AOR = 1.81; 95% CI: 1.12-2.93), methadone treatment enrollment (AOR = 3.47; 95% CI: 1.85-6.95) and having received peer-based education on HCV (AOR = 4.22; 95% CI: 2.66-6.77).
Conclusions: We found one-third of Thai IDU in our sample reporting a history of HCV testing. The finding that IDU who received peer-based HCV education were more likely to access HCV testing provides evidence for the value of peer-based interventions for this population.
