摘要
目的探讨山东省急性乙型病毒性肝炎（乙肝）发病趋势和特征，为评价控制效果，制定乙肝综合防治措施提供参考。方法利用国家法定传染病信息报告系统2005～2012年山东省急性乙肝病例监测数据，采用描述流行病学方法，分析急性乙肝发病趋势和病例分布特征。结果2005～2010年山东省急性乙肝报告发病率呈逐年下降趋势，从2005年的6．02／10万下降至2010年的2．11／10万；2010年后稳定在2／10万左右。病例季节分布不明显。各地区间发病率差异较大，威海市最高，为18．35／10万；泰安、聊城、菏泽三市2010～2012发病率呈上升趋势。病例以25～59岁为主，占全年病例的54．99％（2006年）～62．34%（2011年）；O～14、15～24和40～49岁人群发病率呈逐年下降趋势，但2010年后25～39岁和60岁以上人群报告发病率呈上升趋势。农民发病率较高且其所占构成比呈逐年上升趋势。结论山东省急性乙肝发病逐年下降，应关注泰安、聊城、菏泽等发病率上升地区和25～39岁发病率上升人群。
Objective To explore the epidemicological trend and characteristics and trend of reported acute hepatitis B in Shandong province,during 2005-2010, so as to, to providee reference for policy-making of hepatitis B controlthe sugges- tions for. measures for the prevention and control of hepatitis B. Methods Data about acute hepatitis B cases reported in 2005-2012 in Shandong province were obtained from Using the data from the National Notifiable Disease Reporting Sys- tem （NNDRS） and were analyzed using descriptive epidemiological method~ in Shandong province from 2005 to 2012, using descriptive epidemiological method,analyze the acute hepatitis B incidence trend and epidemiological characteristics. Re- suits Before 2010, Tthe incidence of acute hepatitis B reported incidence decreased year year by year in Shandong pProv- ince,2005-2010,from the 6.02/105 in 2005 to 2.11/10s in 2010,and then,after 2010,itkept＇s stable at around 2/105 after that 10 million. There was no obviously seasonal peak for the incidence of acute hepatitis B. The average incidence was highest in Weihai city,which was as high as 18.35/105. The incidence slowly increased in three cities including Tai＇an,Li- aocheng and Heze,2010-2012. Most cases occurred in the age of 25 to 49,accounting for 54.99~ to 62.34% in the year of 2006 and 2011 respectively. The incidence decreased year by year in the age groups of 0-14 years, 15-24 years and 40-49 years,while it increased in the age groups of 25-39 years and above 60 years after 2010. Farmers accounted for the largest part of the reported cases, seasonal distribution of reported cases of acute hepatitis B is not obvious, the incidence is higher in eastern coastal areas and in 20 to 34 years age group,the incidence of children under the age of 15 decreased by 83.78% Farmers have a higher prevalence and its constituent ratio is rising year by year. Conclusion The incidence of acute hepatitis B in Shandong province shows a downward trend. More attention should be paid to the cities with increased inci- dence including Liaoeheng,Tai＇an and Heze and the young population aged 25 to 39 years.
