摘要
目的通过了解湖北省郧县乙型病毒性肝炎(下称乙肝)流行病学特征,为制定防制对策提供科学依据。方法采用Excel(2003)对疫情作描述流行病学统计分析。结果 2004—2011年共报告乙肝6 896例,年均发病率为137.86/10万;总体发病率呈上升趋势(χ2=7.87,P<0.01);发病无明显的季节性,但3—8月份报告病例较多;农民所占的比例最大,15～59岁年龄组为高发人群,病例占总数的86.83%,儿童与老年人较少;男女性别发病率有较大差异(χ2=747.16,P<0.01);15岁以下人群乙肝报告发病率由2004年的47.50/10万降至2011年的14.62/10万(χ2=19.16,P<0.01)。结论各年份的乙肝报告发病率均高于全省,说明郧县乙肝防治形势严峻,今后应加强乙肝疫苗接种在内的综合防治干预措施。
[Objective]To understand the epidemiological characteristics of viral hepatitis B in Yunxian County of Hubei,provide a scientific basis for developing the prevention and control measures.[Methods]By using Excel（2003）,the epidemic situation of viral hepatitis B was analyzed with descriptive epidemiology.[Results]A total of 6 896 cases of viral hepatitis B were reported during 2004-2011,the average annual incidence rate was 137.86/lakh,and the incidence rate showed an upward trend（χ2=7.87,P0.01）.There was no obvious seasonality,but more cases were reported March to August.Farmers accounted for a large proportion.86.83% of cases were in 15-59 year-old age group,and patients of children and old people were rare.There was a significant difference in incidence rate between males and females（χ2=747.16,P0.01）.The reported incidence rate of hepatitis B in people under 15 years old decreased from 47.50/lakh in 2004 to 14.62/lakh in 2011（χ2=19.16,P0.01）.[Conclusion]The reported incidence rate of hepatitis B every year in Yunxian County is higher than that in Hubei,which indicates that situation of hepatitis B control is grim,so the comprehensive prevention and intervention（including hepatitis B vaccination） should be strengthened in the future.
