目的掌握内蒙古自治区近几年乙肝发病水平和流行特征,为卫生行政部门制定乙肝防治策略提供科学依据。方法采用描述性流行病学方法对内蒙古自治区2004-2012年乙肝的发病情况进行分析,采用spss 13.0对资料进行统计学分析,计数资料使用χ2检验。结果 2004-2012年内蒙古自治区共报告乙肝发病数276 694例,发病率127.3/10万,死亡61例,死亡率0.03/10万,病死率0.02%;全年各月均有乙肝发病,病例呈散发分布,无明显季节高峰;男性发病162 014例,女性114 680例,男女性别比为1.41∶1,不同性别间乙肝发病差异有统计学意义(χ2=4877.44,P<0.01);农民乙肝发病率最高为32.36%,其次为家政(家务、待业)和工人,发病率分别为17.65%和9.30%;发病集中在青高年人群,主要集中在20~65岁年龄组,其中25~岁组平均发病率最高为159.07/10万。结论应加强乙肝重点人群和高发人群乙肝疫苗的主动接种,进一步在不同人群中建立免疫屏障,阻断乙肝的传播。
Objective To grasp the epidemic characteristics of hepatitis B in Inner Mongolia Autonomous Region in recent years and provide a scientific basis for the development of hepatitis B prevention and control strategies by health administrative departments. Methods The descriptive epidemiological method was used to analyze the incidence of hepatitis B in Inner Mongolia Autonomous Region from 2004 to 2012. The data were analyzed by SPSS 13.0, and the count data were analyzed by χ2 test. Results A total of 276 694 hepatitis B cases were reported in Inner Mongolia Autonomous Region from 2004 to 2012, with an incidence rate of 127.3 / 100 000 and 61 deaths, with a death rate of 0.03 / 100,000 and a case fatality rate of 0.02%. There were 162 014 males and 114 680 females with a male / female ratio of 1.41:1. There were significant differences in the incidence of hepatitis B between different sexes (χ2 = 4877.44, P <0.01) The highest incidence was 32.36%, followed by housekeeping (domestic work, unemployed) and workers, the incidence rates were 17.65% and 9.30% respectively. The incidence was concentrated in the elderly population, mainly in the 20-65 age group, of which 25- The highest average incidence was 159.07 / 100,000. Conclusion Hepatitis B vaccine should be actively vaccinated in key hepatitis B patients and high-risk populations, and further to establish immune barrier in different populations to block the spread of hepatitis B.
