Abstract:
Objective To understand the current risk factors of hepatitis B virus(HBV) transmission in Jilin City, in order to provide a scientific basis for formulating targeted prevention and control strategies.Methods A total of 111 patients with hepatitis B were randomly selected as the case group from the China Information System for Disease Control and Prevention during the period from January 1, 2021 to December 31, 2022 in Jilin City, at the same time, one family member of every patient who lived in the same household and was not infected with HBV was selected as the control group. A retrospective questionnaire survey was conducted to collect data on demographic characteristics, clinical information, hepatitis B vaccination history, knowledge of HBV transmission, and potential infection risk behaviors inside and outside the family. The related factors of HBV infection were analyzed by using χ2 test, univariate and multivariate Logistic regression models.Results The case and control groups were comparable in demographic characteristics. In the case group, 55. 86% were HBsAg positive,21. 88% had abnormal liver function, and 14. 41% had clinical symptoms. The definite vaccination rate of hepatitis B vaccine in the case group(5. 41%) was lower than that in the control group(11. 71%). The overall accurate awareness rate of the two groups for HBV transmission routes was only 45. 50%, and 82. 89% of the patients did not know the source of their own infection or had misconceptions. Univariate analysis showed that the risk factors for transmission within the family included sharing toothbrushes(OR = 6. 363, P = 0. 011) and tooth cups(OR = 4. 253, P = 0. 004), and the protective factor was complete vaccination(OR = 0. 028, P = 0. 001). Risk factors for out-of-family transmission included a history of oral cavity(OR = 6. 075, P = 0. 014), a history of other diseases(OR = 3. 178, P = 0. 008), and a history of acupuncture(OR =1. 693, P = 0. 016) and beauty treatment(OR = 1. 657, P = 0. 033). Multivariate Logistic regression analysis determined that the dental history(OR = 5. 075, 95% CI: 1. 665-10. 587) and other medical history(OR = 2. 178, 95% CI: 2. 050-5. 633)were risk factors for HBV infection, while having a history of vaccination was a protective factor(OR = 0. 609, 95% CI: 0. 388-1. 081).Conclusion The vaccination rate of hepatitis B vaccine and the awareness rate of prevention and control knowledge of adult hepatitis B patients and their families in Jilin City had been both low. Sharing personal hygiene products(toothbrushes and tooth cups) in the family and invasive medical services and beauty behaviors outside the family(such as dental treatment and acupuncture) are important risk factors for local HBV transmission. Hepatitis B vaccination is an effective protective measure. According to these risk factors, health education and behavioral intervention for key populations should be strengthened, and the vaccination coverage rate of hepatitis B vaccine should be improved.
