[目的]了解2004～2009年大连市乙肝、麻疹、风疹、流行性腮腺炎等部分免疫可预防传染病流行特征。[方法]利用传染病疫情数据库资料,运用描述流行病学方法对大连市部分免疫可预防传染病流行特征进行统计分析。[结果]2004年与2009年比较,乙肝发病呈明显下降态势(P﹤0.01);麻疹发病率2005年有所回升,2006年达高峰以后逐年下降(P﹤0.01);风疹发病率自2007年以后逐年下降(P﹤0.01);流行性腮腺炎发病率2009年与2008年比较下降了52.6%。2004～2009年城区、郊区、农村4种免疫可预防传染病年均发病率分别为77.83/10万、135.44/10万、32.91/10万,郊区﹥城市﹥农村(P﹤0.01);男性、女性年均发病率分别为90.72/10万、51.52/10万,男性发病明显高于女性(P﹤0.01);乙肝年均发病率20～44岁最高,麻疹年均发病率﹤1岁最高,流行性腮腺炎和风疹发病主要集中在5～20岁年龄段。[结论]2004～2009年大连市乙肝、麻疹、风疹、流行性腮腺炎发病率呈明显下降趋势。
[Objective] To understand the epidemic characteristics of infectious diseases that can prevent some hepatitis B, measles, rubella and mumps in Dalian from 2004 to 2009. [Method] With the information of epidemic situation database of infectious diseases, the descriptive epidemiological method was used to analyze the epidemiological characteristics of some immune-preventable infectious diseases in Dalian. [Results] Compared with 2009, the incidence of hepatitis B decreased significantly (P <0.01). The incidence of measles rose in 2005 and declined year by year after reaching its peak in 2006 (P <0.01). The incidence of rubella has been increasing since 2007 Year after year (P <0.01). The incidence of mumps dropped 52.6% in 2009 compared with 2008. The average annual incidence rates of four kinds of immunodeficiency preventable infectious diseases in urban, suburban and rural areas from 2004 to 2009 were 77.83 / 100000, 135.44 / 100000 and 32.91 / 100000, respectively; suburbs> cities> rural areas (P <0.01) The annual average incidence of hepatitis B was 90.72 / 100000, 51.52 / 100000, the incidence was significantly higher in males than in females (P <0.01). The annual average incidence of hepatitis B was the highest in 20-44 years, the average annual incidence of measles was <1 year, Mumps and rubella incidence mainly concentrated in the 5 to 20 age group. [Conclusion] The incidence of hepatitis B, measles, rubella and mumps in Dalian from 2004 to 2009 showed a significant decrease.
