目的了解成都铁路局辖区饮食从业人员、公共场所从业人员乙肝病毒感染状况。方法以2003-2008年铁路辖区47 105名从业人员为研究对象,检测HBsAg。结果 2003-2008年共检查47105人次,检出HBsAg阳性携带者1344人次,阳性率为2.9%,最高2004年为4.0%,最低2007年为1.9%,各年度HBsAg阳性率差异具有统计学意义(P<0.05)。成都地区、宝成沿线、成渝沿线HBsAg阳性率分别为3.0%、2.2%和3.9%,3个地区HBsAg阳性率差异具有统计学意义(P<0.01)。饮食从业人员、公共场所从业人员HBsAg阳性率分别为2.8%、3.0%,各年度阳性率差异无统计学意义(P>0.05)。男性和女性在各年度中的年龄组比较差异具有统计学意义(P<0.05),其中20岁以下组的阳性率最高,分别为6.8%和4.8%。40~50岁年龄组阳性率相对较低。结论 2003-2008年成都铁路局辖区的从业人员HBsAg阳性携带情况呈现阳性率低,男性高于女性,低年龄组高及成渝沿线较高的特点。
Objectives To understand the status of hepatitis B virus infection among employees engaged in catering and public places in Chengdu Railway Bureau. Methods A total of 47 105 workers in the railway area from 2003 to 2008 were selected as the research object to detect HBsAg. Results A total of 47105 person-times were detected in 2003-2008, of which 1344 were HBsAg-positive carriers. The positive rate was 2.9%, the highest rate was 4.0% in 2004 and the lowest rate was 1.9% in 2007. The positive rate of HBsAg in each year was statistically significant P <0.05). The positive rates of HBsAg in Chengdu, Baocheng and Chengdu-Chongqing areas were 3.0%, 2.2% and 3.9%, respectively. The positive rates of HBsAg in three areas were statistically significant (P <0.01). The positive rates of HBsAg in diet practitioners and public places employees were 2.8% and 3.0% respectively, there was no significant difference in the positive rates of each year (P> 0.05). There was significant difference between male and female age groups in each year (P <0.05), of which the highest positive rate was 6.8% and 4.8% in the group of 20 years and younger respectively. The positive rate of 40 ~ 50 age group is relatively low. Conclusion From 2003 to 2008, the HBsAg positive carriers of employees in Chengdu Railway Bureau area showed a low positive rate, which was higher in males than in females, in low age groups, and higher in Chengdu-Chongqing area.
