Abstract:
Objective To analyze and discuss the epidemiological characteristics of HBV infection in people with hepatitis B virus (HBV) surface antigen (HBsAg) positive in Deyang Area. Methods The health checkup information of the region in 2020 was selected to screen the subjects with the results of HBV serological markers, and 1645 HBsAg-positive patients were selected as the main subjects to analyze the epidemiological characteristics of the population. Use Epidata to enter data, and use SPSS statistical software package to analyze the data. Results Except for the differences in occupational distribution between the sexes, the differences in age, education level, family history, and vaccination history (hepatitis B vaccine) were not statistically significant among men and women in this study. Among the 1645 HBsAg-positive subjects, 41 were double-positive for anti-HBs at the same time, and the double-positive rate was 2.49%. Compared with HBs-negative people, HBs-positive people have a relatively higher proportion of males, junior high school education level, occupation as a farmer, unvaccinated, and positive family history. AmpliPrep/COBAS quantitative detection reagent was used for HBV DNA viral load detection, 92.69% were quantitatively positive (38 cases), of which 23 cases (60.53%) with HBV DNA < 20 IU/mL, and 15 cases (39.47%) with HBV DNA >20 IU/mL). The epidemiological characteristics of the double-positive population suggest that the proportion of males, junior high school education level, occupation as a farmer, unvaccinated and positive family history is relatively higher. Analyzing the potential influencing factors of anti-HBs positive (double positive) in HBsAg-positive people, it can be seen that the increase in age, the occupation is a farmer, the first injection of hepatitis B vaccine is not in time, and the family history of liver disease is positive as potential risk factors for the occurrence of double positive. Conclusion In the future, this region should pay special attention to farmers who are older, have a family history of liver disease, and lack or incomplete hepatitis B vaccination for hepatitis B prevention and control.
