ABSTRACT
Objective To understand the status quo and analyze the influencing factors of new hepatitis B virus(HBV) infection in Anzhou district,Mianyang city,Sichuan province,so as to provide a scientific basis for the formulation of hepatitis B prevention and control measures.Methods This study enrolled 71 418 residents of Anzhou District,Mianyang City,who participated in the physical examination of “Mianyang Comprehensive Prevention and Control Demonstration Study of Major Infectious Diseases” in 2013 and were tested negative for the hepatitis B surface antigen.The residents were followed for 5 years and underwent serological test again in 2018.The new infection rate of HBV was calculated and the influencing factors were analyzed by multivariate Logistic regression analysis.Results In 2018,the new infection rate of HBV among 71 418 residents in Anzhou district was 1.61%.The new infection rate varied with the differences in gender,age,occupation,marital status,smoking status,drinking frequency,place of residence,family history of hepatitis B,and history of hepatitis B vaccination(P<0.001).Multivariate Logistic regression results showed that male(OR=1.29,95%CI=1.12-1.48,P<0.001),farmer(OR=2.01,95%CI=1.39-2.90,P<0.001),and family history of hepatitis B(OR=1.97,95%CI=1.44-2.70,P<0.001)were the independent risk factors for new HBV infection(P<0.001).Conclusions The new infection rate of HBV is high in Anzhou district of Mianyang city.Males,farmers,and those with family history of hepatitis B are high-risk groups of HBV infection.
