[目的]调查某部新兵乙肝表面抗体(抗-HBs)携带情况,为进一步作好乙肝疫苗接种工作提供依据。[方法]选取某部2007、2008、2009年度入伍新兵共计755人,分别按入伍时间和年龄分为3组,采用酶联免疫吸附试验进行乙肝表面抗体(抗-HBs)检测。应用方差分析作统计学处理。[结果]755名被检新兵共检出抗-HBs阳性210人,阳性率为27.81%。按入伍时间分组显示:2007年阳性率22.09%,2008年阳性率25.44%,2009年阳性率35.86%,抗-HBs阳性率逐年增高,三组间比较差异有统计学意义(P<0.01);按年龄分组显示:1990年出生的新兵阳性率29.65%,1991年出生的新兵阳性率27.27%,1992年出生的新兵阳性率23.30%,抗-HBs阳性率逐年降低,3组间比较差异有统计学意义(P<0.01)。[结论]入伍新兵抗-HBs阳性率有逐年上升趋势,但低年龄新兵有下降趋势,应加强监测和疫苗接种工作。
[Objective] To investigate the situation of carrying HBsAg (anti-HBs) in some recruits and provide basis for further hepatitis B vaccination. [Method] A total of 755 recruits from 2007-2008 were enrolled in this study. They were divided into three groups according to the age and age of enlistment. Enzyme-linked immunosorbent assay (ELISA) was used to detect the anti-HBs. Analysis of variance was used for statistical analysis. [Results] A total of 210 positive anti-HBs were detected in 755 recruits, the positive rate was 27.81%. According to the time of enlistment, the positive rate was 22.09% in 2007, the positive rate was 25.44% in 2008, the positive rate was 35.86% in 2009, the positive rate of anti-HBs increased year by year, the difference was statistically significant among the three groups (P <0.01); According to the age group, the recruit rate was 29.65% in 1990, the recruit rate was 27.27% in 1991, the recruit rate was 23.30% in 1992, and the positive rate of anti-HBs was decreasing year by year Significance (P <0.01). [Conclusion] The positive rate of anti-HBs among newly recruits recruited has a rising trend year by year, but the recruits with lower age have a declining trend. Monitoring and vaccination should be strengthened.
