Risk factors for hepatitis B and C among healthy population: a community-based survey from four districts of Southern Italy

In Southern Italy, viral hepatitis B and C still represent an important public health problem, with a serious social impact, and significant economic consequences. The objective of our community-based study was to assess the prevalence of risk factors and access to the test for viral hepatitis to get information for guiding prevention and screening strategies in our setting. The study was conducted among population of four selected districts in Southern Italy during May 2019. An anonymous structured questionnaire consisting of multiple-choice questions was administered by trained research assistants in order to assess any possible risk factor for HCV or HBV acquisition, and if any screening was previously performed. Six-hundred participants were included: 367 (61.2%) were females, with a mean age of 51 years (standard deviation, SD: 18 years). The three most frequent risk factors were: dental treatments in 425/600=70.8% (of whom 76/425=17.8% were previously tested), unprotected sexual intercourses in 340/600=56.6% (of whom 54/340=15.8% were previously tested), and injections with glass syringes in 162/600=27% (of whom 32/162=19.7% were previously tested). Only 47/502 (9.3%) patients who were never been tested, did not report any risk factors for HCV or HBV acquisition, while 433 (86.2%) reported at least one risk factor, 293 (58.3%) at least two, 97 (19.3%) at least three, 16 (3.1%) at least four, and 2 reported to have at least five risk factors for HBV/HCV acquisition.
