We extracted and aggregated data on HCV antibody test, sociodemographic characteristics, alcohol and drug use, depression, sexual behaviour and sexually transmitted illnesses from 2005-2006 to 2011-2012. The study sample was restricted to men and women aged 20-59 years given the upper age limit of the risk factors used for the analysis.</p><p><strong>Results: </strong>Overall, 11,593 people were included in the analysis (52.2% female). Higher prevalence of HCV, excessive alcohol consumption and drug use were found in men. Men also had higher odds of HCV in comparison to women among younger (20-39 years old) OR 1.37 (95%CI 1.36-1.37) and middle-aged adults (40-59 years old) OR 2.04 (95%CI 2.03-2.04). Among younger adults, non-Hispanic black and Hispanic people were found to have a lower likelihood of testing positive, OR 0.35 (95%CI 0.35-0.35) and OR 0.30 (95%CI 0.30-0.30), respectively. However, in the middle-aged adults non-Hispanic black people were found to have a higher likelihood of testing positive OR 1.45 (95%CI 1.45-1.46). Analysis showed that for each additional risk factor associated with HCV infection there is an additional increase in the risk OR 1.55 (95%CI 1.55-1.55).</p><p><strong>Conclusions: </strong>For every additional risk factor for HCV a person is exposed to, the overall risk of HCV increases.</p> ER -
