A survey of knowledge about hepatitis B among new military recruits in China

Background: Hepatitis B is a disease that affects the liver and is caused by the hepatitis B virus(HBV). Hepatitis B is a serious public health problem in China. The objective of this study was to assess knowledge of and behaviours towards the transmission and prevention of hepatitis B of new military recruits in China.Methods: A cross-sectional study was conducted among 800 new military recruits. A self-administered, structured questionnaire was used to collect information, and 727 questionnaires were returned completed. Analysis was performed using SPSS 18.0, and P<0.05 was considered statistically significant.Results: Of the respondents, 665(91.5%) were male and 62(8.5%) were female. The mean age was 18.9±1.7 years. A total of 608 respondents(83.6%) demonstrated poor knowledge and 119(16.4%) adequate knowledge about HBV. Older age, female and higher education level were statistically associated with a higher mean knowledge score. Multivariate logistic regression showed that age(OR=3.040, 95%CI 1.724–5.359, P<0.001) and gender(OR=1.791, 95%CI 1.325–2.421, P<0.001) were significantly associated with appropriate behavioural practices towards prevention of HBV.Conclusion: Against a backdrop of high HBV prevalence in China, new military recruits had poor knowledge of HBV. New recruits need better education about HBV to assist in reducing and preventing HBV infection.
