Objective: The purpose of this study is to develop a model predicting Hepatitis A (HAV) infection among Black, Hispanic and White injection drug users. Methods: Current and former injection drug users in western Los Angeles County were recruited through the Hepatitis Demonstration Project. Participants were tested for Hepatitis A, B, C and HIV and completed the Risk Behavior Assessment (RBA). We modeled hepatitis A infection using a multiple logistic regression model. Results: Risk factors for HAV infection are positive test result for Hepatitis B (HBV) (OR= 3.5, 95% CI=2.45,5.14) and Hepatitis C (HCV) infection (OR=2.2, 95% CI=1.44, 3.32), Hispanic ethnicity (OR=1.9, 95% CI=1.28, 2.88), ever traded sex for money (OR=1.66, 95% CI=1.14, 2.41). The only protective factor against HAV infection is self -reported crack use (OR=.49, 95% CI=.29, .83). Conclusions: These findings further support the promotion of HAV and HBV vaccination of IDUs due to the strong relationship between infection with these three forms of Hepatitis. Further research is necessary to explore the relationship between HAV and Hispanic ethnicity.
