Prevalence of HCV risk factors in Hispanic-American sub populations.

To assess the prevalence of HCV risk factors among Hispanic-American subpopulations in Philadelphia. Patients from four primary care practices in Philadelphia were enrolled. Demographics and HCV risk factors were ascertained using a self-administered questionnaire. Five hundred and three patients who identified themselves as Hispanic or Latino were included in the study. Approximately half were born in Puerto Rico or mainland US and the remaining participants were born in 19 other countries. One quarter or less of individuals born in these countries reported having a HCV risk factor. In comparison, 45% of individuals born in Puerto Rico and mainland US reported having a HCV risk factor. With each year individuals born outside the US live in the US, odds of having a risk factor increased by approximately 7% (P = 0.014). US born Hispanics are more likely to have a HCV risk factor than Hispanics born outside the US. Furthermore, the prevalence of risk factors increase among Hispanic immigrants after living in the US. These findings have a direct public health impact by providing rationale to focus HCV prevention efforts on recent immigrants.
