目的:探讨15岁以下儿童的乙肝血清学检测与乙肝疫苗接种状况。方法:随机抽取2012年9月~2014年12月入学的学生作为本次研究对象,共计1000例学生,学生来源为我5个市区、4个直辖村,分别定义为市区组和直辖村组。分析(1)市区组和直辖村组乙肝血清学检测结果。(2)不同年龄学生乙肝疫苗接种率。结果:(1)市区组和直辖村组HBsAg阳性率、HBsAb阳性率分别为(2%、59%)、(8%、43.4%),结果比较有差异(P<0.05)。(2)小于9岁组、10~11岁组、12~13岁组、大于13岁组乙肝疫苗接种阳性率分别为94.9%、88.8%、82.8%、74.4%,结果比较有差异(P<0.05)。结论:本次研究认为市区学生HBsAg阳性率明显低于农村学生;市区学生HBsAb阳性率高于农村学生;随着年龄的增加,学生乙肝疫苗接种率明显下降。
Objective: To investigate the serological detection of hepatitis B and hepatitis B vaccination in children under 15 years of age. Methods: Students randomly selected from September 2012 to December 2014 were enrolled in this study. A total of 1000 students were enrolled. The students were from 5 urban areas and 4 directly administered villages, which were defined as urban district groups and directly under the jurisdiction of the village group. Analysis (1) Hepatitis B serological test results in urban area and directly under the village group. (2) Hepatitis B vaccination rate of students of different ages. Results: (1) The HBsAg positive rate and HBsAb positive rate in urban district group and directly administered village group were (2%, 59%) and (8%, 43.4%, respectively). (2) The positive rates of hepatitis B vaccination in patients younger than 9 years old, 10 to 11 years old, 12 to 13 years old and older than 13 years old were 94.9%, 88.8%, 82.8% and 74.4%, respectively (P < 0.05). Conclusion: This study suggests that the positive rate of HBsAg in urban students is significantly lower than that in rural students. The positive rate of HBsAb in urban students is higher than that of rural students. With the increase of age, the HBsAg vaccination rate of students drops obviously.
