Abstract:
To analyze the test results of five serum markers of hepatitis B virus (HBV) among university freshmen from 2007 to 2012.Among a total of 10 827 freshmen,there were 5 021 freshmen from 2007 to 2009 with all five serum markers.The overall ratio of HBsAg positive was 4.5％,4.8％,4.8％ and 4.0％ for each year.And it had no statistically significant difference.The overall ratio of single-HBsAb positive was 34.8％,37.4％,29.0％ and 37.9％ for each year and the figure of 2008 was lower than those of 2007 and 2009 (P ＜ 0.01).The overall ratio of five markers all negative were 58.3％,55.4％,63.9％ and 55.8％ for each year and the figure of 2008 was higher than those of 2007 and 2009 (P ＜ 0.01).And 34.5％ of HBsAg positive freshmen were HBsAg(+),HBeAg (+),HBcAb (+) and 44.2％ HBsAg(+),HBeAb(+),HBcAb(+).The prevalence ratio of HBsAg for males was higher than that for females (5.1％ vs.3.2％,P ＜0.01).Among 5 806 freshmen tested during 2010-2012,522(9.0％) had a serum level of alanine transaminase (ALT) ＞ 40 U/L,including HBsAg positive (n =12),single anti-HBs positive (n =213) and five negatives (n =288).Approximate 50％ university freshmen have no anti-HBs indicating a low level of immunity.And the students should acquire the knowledge of hepatitis B,improve the ratio of vaccination,strengthen the monitoring and prevent its spread through concerted measures.
