泰州市2005-2010年20岁以下人群肺结核流行特征分析

Analysis on reported tuberculosis among population younger than 20 years in Taizhou City,2005-2010

目的分析泰州市2005-2010年20岁以下人群肺结核报告特征,探讨青少年儿童肺结核病流行趋势,为控制肺结核在青少年儿童中的流行提供依据。方法从年龄、性别、报告时间和痰菌检测结果等方面对国家疾病监测信息报告管理系统报告的泰州市2005-2010年20岁以下人群肺结核相关资料进行描述性分析。结果泰州市2005-2010年20岁以下人群肺结核报告病例861例,男女比例1.47∶1,为同期全人群平均报告肺结核病例的3.8%,2005、2010年报告发病率分别为13.06/10万、7.12/10万,2010年比2005年下降45.48%。2005-2010年20岁以下人群中,15岁以下人群发病率低于8/10万,15~19岁出现发病突增现象;肺结核报告集中在3~10月,报告病例数占78.4%,且涂阳病例构成比在33.9%~45.7%之间波动,平均为37.5%,低于同年全人群报告涂阳病例构成比45.9%~59.3%,平均为53.1%。结论 3~10月是肺结核高发季节。20岁以下人群肺结核发病率远低于全人群,2007年后呈下降趋势。涂阳病例构成比低于全人群,15岁以下人群低发,15~19岁组发病机会增加,其中男性较女性高发。

Objective To master tuberculosis epidemiology among population younger than 20 years in Taizhou City,2005-2010.Methods Tuberculosis cases of younger than 20 years in Taizhou（2005-2010） were collected for analysis of descriptive epidemiology.Results During 2005 to 2010,861 cases were reported,consisting of 3.8% of all cases reported,male accounted 59.5%（512/861） while female accounted 40.5%（349/861）.The incidence of 2010 was 7.12/100 000,45.48% lower than that of 2005（13.06/100 000）.The incidence of population younger than 15 years was lower than 8/100 000,while that of 15~19 increased greatly.78.4% cases occurred between March and October,smear positive cases accounted 33.9%~45.7% of all cases reported,37.5% averagely,which was lower than that of the whole population.Conclusions Population younger than 20 years was not at high risk of tuberculosis and the decreasing tendency of incidence continued since 2007.Most cases occurred between March and October,the incidence of population younger than 15 years was rather low,but it increased rapidly after age of 15 and there is no need to conduct tuberculin screening among primary and junior students.
