目的了解古交市乙型病毒性肝炎(乙肝)的流行规律,为开展乙肝防控工作提供依据。方法查阅中国疾病预防控制信息系统的疾病监测信息报告管理系统获得疫情资料,按发病日期、本县区分年度统计,病例全部为实验室诊断病例。人口资料来源于中国疾病预防控制信息系统的基本信息系统。对统计资料进行描述性分析,发病率和构成比及相关图表用WPS表格计算生成,计数资料用χ2检验,P<0.05为差异有统计学意义。结果 2004—2012年每年每月都有病例报告,1—2月发病数最少,发病数分别为211例、224例;3月份发病数最高,发病数371例。月份发病数中位数为304.5例,无明显的月份差异(均P>0.05)。除151例地区不详外,每年每个地区都有病例报告。发病率最高的是马兰镇(392.49/10万),邢家社乡最低(57.88/10万)。总体上市区街道和山西焦煤集团矿区所在的乡镇高于其他乡镇(P<0.05)。病例主要集中于工人(25.92%)、家政家务与待业(22.26%)和农民(20.17%)。年龄别累积发病率50～59岁组最高(264.30/10万),0～9岁组最低(26.82/10万)。性别分布男高于女,男性累积发病率为225.55/10万,女性累积发病率为137.53/10万,男女发病率之比为1.64:1。结论古交市通过加强儿童乙肝疫苗免疫,有效控制了儿童乙肝发病率,但发病率仍然很高,同时存在病例报告不规范等问题,需继续巩固儿童乙肝疫苗的免疫接种成果,重点加强医疗机构管理。
Objective To understand the prevalence of hepatitis B virus (HBV) in Gujiao City and provide the basis for hepatitis B prevention and control work. Methods Access to disease surveillance information reporting management system of China’s disease prevention and control information system Obtain epidemic information, according to the date of onset, the county is divided into annual statistics, all cases of laboratory diagnosis. Population information comes from the basic information system of China’s disease prevention and control information system. The descriptive analysis of statistical data, morbidity and composition ratio and related charts generated using the WPS table, counting data using χ2 test, P <0.05 for the difference was statistically significant. Results The cases were reported from January to February every year from 2004 to 2012, with the lowest number of cases in January-February. The number of cases was 211 cases and 224 cases respectively. The highest incidence in March was 371 cases. The median incidence of the month was 304.5 cases, no significant differences in the month (all P> 0.05). With the exception of 151 districts, there are case reports in each region each year. The highest incidence of Malan town (392.49 / 100000), Xing community lowest (57.88 / 100000). In general, the townships in the downtown streets and the Shanxi Coking Coal Mine are located higher than the other towns (P <0.05). The cases mainly focused on workers (25.92%), housekeeping and unemployed (22.26%) and peasants (20.17%). The cumulative incidence of age group 50 to 59 years old was the highest (264.30 / 100,000), 0 to 9 years old the lowest (26.82 / 100,000). The male sex ratio was higher than that of female, with a cumulative incidence rate of 225.55 / lakh for males and 137.53 / lakh for females. The ratio of male to female was 1.64: 1. Conclusions Gujiao City has effectively controlled the incidence of hepatitis B in children through strengthening the immunization of children’s hepatitis B vaccine, but the incidence rate is still high. At the same time, there are some problems such as non-standard case reports. The immunization results of children’s hepatitis B vaccine need to be further strengthened, with a focus on strengthening the medical institutions management.
