外来务工子弟学校学生乙肝病毒感染状况及防治对策

Hepatitis B infection in school children of migrant workers and strategy of its prevention and control

目的了解外来打工子弟学校学生乙肝病毒感染情况,为制定防治策略提供依据。方法采用多阶段整群系统抽样法,检测调查对象HBsAg和抗-HBc两项指标。结果外来打工子弟学校学生HBsAg和抗-HBc阳性率高于本市儿童水平;2项指标阳性率在性别间差异均无统计学意义(χ2=0.143,P=0.705;χ2=0.025,P=0.873);2项指标阳性率呈现随年龄增长而上升趋势(χ2=6.733,P=0.009;χ2=22.04,P<0.01);不同经济发达程度的现居住地间,2项指标阳性率差异无统计学意义(χ2=0.111,P=0.739;χ2=2.92,P=0.087)。结论外来打工子弟学校学生乙肝病毒感染状况较本地学生严重,应将流动人口纳入本地人口的管理体系。

Objective To figure out current status of viral hepatitis B （HB） infection in the school children of migrant workers to provide information for developing the strategy of its prevention and control. Methods Multi-phase cluster sampling was used to detected serum HBsAg and anti-HBc in the target groups. Results （1） Prevalence of positive HBsAg and anti-HBc among school children of migrant workers was higher than that in children of permanent residents. （2） No remarkable difference in prevalence of serum HBsAg and anti-HBc between boys and girls was found （ x^2 = 0. 143, P = 0. 705 ; x^2 = 0.025, P = 0. 873 ）. （3） Prevalence of serum positive HBsAg and anti-HBc increased with the age of children （x^2 = 6.733, P = 0.009; x^2 = 22.04, P 〈 0.01）. （4） No remarkable difference in HBsAg and anti-HBc between cities of different level of economic development, where they are living now （x^2 = 0.111, P = 0.739 ; x^2 = 2.92, P = 0. 087）. Conclusion （ 1 ） HB infection in school children of migrant workers was more serious than in those of local residents. （2） Children of migrant workers should be managed as children of local residents.
