Background: The US Baby Boomer (BB) generation is associated with high rates of Hepatitis C virus (HCV) infection. There is limited literature detailing age-specific risk factors for HCV infection. Using a nationally representative sample, this study examines US adult HCV prevalence and age-specific risk factors for chronic HCV infection. Methods: We analyzed data from National Health and Nutrition Examination Survey (NHANES) for years 1999-2012. Age was divided into three categories: BB, younger than BB (YG) and older than BB (OG). HCV status was determined by the presence of a positive HCV antibody and a positive HCV RNA. Sociodemographic variables were analyzed by HCV status. Multivariable logistic regression models adjusting for sociodemographic variables were fitted to identify age-specific risk factors for HCV positivity. Results: The overall prevalence of chronic HCV was 1.19% with a US population estimate of 2,347,852 US adults. BB had the highest prevalence at 2.23%, accounting for over 74% of all chronic HCV cases. HCV prevalence was highest among all ages (1.83%) and BB (2.71%) in 2001-2002 survey cycle. Among BB, males, non-Hispanic blacks, positive blood transfusion history, current and former smoker, and living below the poverty line were significant predictors of chronic HCV positivity. Conclusion: This study highlights the elevated prevalence of chronic HCV among BB and identifies age-specific risk factors for chronic HCV infection. As the BB population ages, it is important to use these generation-specific risk factors that can guide health professionals in targeted screening and public health prevention efforts.
