目的了解平泉县2004-2008年乙肝流行趋势,为进一步控制乙肝的发病和流行提供科学依据。方法采用描述性流行病学方法对2004-2008年平泉县乙肝疫情资料进行统计分析。结果2004-2008年平泉县共报告乙肝1463例,其中当年新发病例是1 014例,占报告乙肝病例的69.31%,新发病例年平均发病率为43.35/10万。发病率有下降趋势,最高年发病率是最低年的4.7倍。男性发病率高于女性,男女发病率比为1.37∶1。高发年龄在20 49岁组。职业分布以农民、学生为主,发病率分别为24.8/10万、6.11/10万。地区分布以平泉镇最多,发病率为9.92/10万。结论平泉县乙肝发病率虽有下降趋势但还未稳定控制,发病主要以青壮年农民及学生为主,主要分布在人口密集、人员流动性大的城镇,还应加大预防控制力度。
Objective To understand the epidemic trend of hepatitis B in Pingquan County from 2004 to 2008 and to provide a scientific basis for further controlling the incidence and prevalence of hepatitis B. Methods Descriptive epidemiological methods were used to analyze the data of hepatitis B in Pingquan County from 2004 to 2008. Results A total of 1463 cases of hepatitis B were reported in Pingquan County from 2004 to 2008, of which 1 014 cases were newly diagnosed in that year, accounting for 69.31% of the reported hepatitis B cases. The average annual incidence of new cases was 43.35 / 100000. The incidence has a downward trend, the highest annual incidence rate is 4.7 times the minimum year. The incidence of males is higher than that of females, the incidence rate of males and females is 1.37: 1. High in the age group of 20 49 years old. Occupation distribution to farmers, students, the incidence rates were 24.8 / 100,000, 6.11 / 100,000. The most area is Pingquan town, with a prevalence of 9.92 / 100,000. Conclusions Although the incidence of hepatitis B in Pingquan County has been declining, the incidence of hepatitis B has not yet been steadily controlled. The incidence is mainly dominated by young and middle-aged peasants and students, mainly in cities and towns with dense population and large staff turnover, and prevention and control should also be intensified.
