【摘要】 目的了解内蒙古自治区(内蒙古)近20年乙型病毒性肝炎(乙肝)的流行特征,科学评价内蒙古乙肝流行状况,为下一步的乙肝防治工作提供理论依据。方法应用Excel软件对1991～2010年内蒙古乙肝监测资料进行统计分析。结果 1995年以后乙肝发病呈快速上升阶段,2003年后呈直线上升阶段,2008年开始呈现下降趋势;年均发病率为79.41/10万,最高发病率为140.58/10万;散发为主;男性发病多于女性;以农民发病最多;15～59岁年龄组的发病人数最多,占86.35%;15岁以下人群发病呈逐年下降趋势;急性发病的人数有所下降,慢性发病的人数有所上升,可明确分类诊断的比例有所提高;慢性病例集中在15～64岁人群,60岁以上人群慢性发病呈明显上升趋势。结论乙肝疫苗逐步纳入儿童免疫规划对内蒙古地区人群乙肝发病率的降低起到重要作用,乙肝的防治工作任重道远。更多还原

【Abstract】 OBJECTIVE To understand the epidemiological features of hepatitis B and evaluate the prevalence of hepatitis B in Inner Mongolia Autonomous Region from1991 to 2010,and provide a theoretical basis of prevention and treatment of hepatitis B in future.METHODS Statistical analysis was conducted to analyze the monitoring data of hepatitis B in Inner Mongolia from1991 to 2010 with Excel software.RESULTS The incidence of hepatitis B was rapidly rose since 1995,a linearly and rapidly upswing stage was showed after 2003.The downward trend was begin in 2008;The average annual incidence of hepatitis B was 79.41 /lakh,and the highest incidence was 140.58 /lakh;The epidemics areas of hepatitis B were general sporadic distribution;The incidences of male were more than female;Farmer was the highest incidences in all occupations;The incidences of 15-59 age group was the maximum,accounting for 86.35%;The incidence was showing declining trend in 0-14 age group;The acute cases showed annually declining trend and chronic cases showed annually rising trend,and the ratio of clearly diagnostic classification improved year by year;Chronic cases were concentrated in 15-64 age group,and chronic disease have showed a clear upward trend after 60 years old.CONCLUSION Results revealed that the hepatitis B vaccine was gradually introduced into the expanded program on immunization(EPI),and this performance could effectually reduce incidence of hepatitis B,especially for 0-14 age group in Inner Mongolia.Prevention and control of hepatitis B have a long way to go.更多还原
