摘　　要：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，检验。结果2004—2012年内蒙古自治区共报告乙肝发病数276694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162014例，女性114680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（x^2=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25一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 evaluate the prevalence of hepatitis B and master the epidemiological features of hepa- titis B in Inner Mongolia in recent years , provide scientific basis of prevention and treatment strategy of hepa- titis B in the future. Methods Descriptive epidemiology was conducted to analyze the incidence of hepatitis B during 2004 - 2012 with spssl3.0, to count data by using the chi - square test. Results From 2004 to 2012, a total of 276, 694 cases of hepatitis B were reported in Inner Mongolia with the incidence of 127.3/lakh, 61 cases died, the mortality rate was 0. 03/lakh, the mortality rate was 0.02% ; incidence of hepatitis B cases were dissemination of distribution each month throughout the year, no significant seasonal peaks ; the incidence of male were 162, 014 cases, female were 114, 680 cases, the male to female ratio of 1.41： 1, the incidence of hepatitis B in the different gender was statistically significant （ X^2 = 4877.44, P 〈 0.01 ） ; farmers inci-dence of hepatitis B up to average incidence rate of 32. 36% , followed by housekeeping （ housework, unem- ployed） and workers, the incidence rate were 17.65% and 9.3% respectively; the incidence is concentrated in the youth age group, mainly concentrated in the 20 - 65 years age group, of which 25 years old group up to 159.07/lakh. Conclusions Active vaccination of hepatitis B should be strengthen to key population and high incidence group, build the immune barrier further, to block the transmission of hepatitis B .
