长沙市2007-2008年食品及公共场所从业人员乙肝表面抗原携带率分析

Analysis on Carrier Rate of Hepatitis B Surface Antigen Among Foodstuff and Public Place Practitioner in Changsha from 2007 to 2008

目的了解长沙市食品及公共场所从业人员乙肝表面抗原（HBsAg）携带情况，为该市乙肝防控提供依据。方法对2007—2008年长沙市从业人员健康体检资料进行统计分析。结果2007—2008年从业人员HBsAg阳性率分别为3．80％、3．27％，HBsAg阳性率男性为4．31％，女性为2．78％，性别差异有统计学意义（P〈0．001）；不同年龄组中31～40岁年龄段为最高3．82％，51～岁以上为2．52％；2007—2008年二年HBsAg阳性率差异有统计学意义（P〈0．001）。结论长沙市食品及公共场所从业人员乙肝表面抗原（HBsAg）携带阳性率呈逐年下降趋势，反映在加强乙肝预防的健康教育、从业人员健康体检率提高、对易感人群进行乙肝疫苗接种所取得的成效，但保持人群低水平乙肝表面抗原（HBsAg）携带率仍需要加强乙肝预防的健康教育，提高乙肝疫苗接种率等干预措施。

Objective To know the carrier rate of hepatitis B surface antigen （HBsAg） in foodstuff and public place practitioners in Changsha, and to provide a basis for hepatitis B prevention and control. Method The health physical examination data of practitioners in Changsha during the period of 2007--2008 were statistically analyzed. Results The HBsAg positive rate of the practitioners was 3.80 % in 2007 and 3.27 % in 2008 respectively. The HBsAg positive rates of males and females were 4.31% and 2. ？8% respectively, and the gender difference was statistically significant （P 〈 0.001 ）. Among the different age groups, the age group of 31 --40 years was the highest （3.82%）, followed by the age group of over 51 years （2..52%）. There was statistically significant difference in the HBsAg positive rate between 2007 and 2008 （P 〈 0.001）. Conclusions The HBsAg carrier rate of foodstuff and public place practitioners in Changsha decreases year by year, which is the achievement resulted from enhancing health education on hepatitis B prevention, increasing health examination rate of practitioners, and carrying out hepatitis B vaccine inoculation in susceptible population; butto keep the low level of HBsAg carrier rate, it is still necessary to strengthen health education on hepatitis B prevention and increase hepatitis B vaccine inoculation rate.
