2010～2012年广西部分地区在校学生结核病筛查结果分析

Analysis on tuberculosis screening results among school students in some area of Guangxi during 2010 to 2012

目的了解学校结核菌素(PPD)试验开展情况、结核病发病水平及强阳性结果相关影响因素,为广西学生结核病体检制度的建立提供理论依据。方法对参与调查学生开展PPD筛查;对所有PPD试验强阳性学生及有肺结核可疑症状学生、疑似病例进行胸部X线片及痰涂片检查;对PPD强阳性与非强阳性学生的相关因素进行比较分析。结果接受PPD筛查学生53217例,阳性率5.74%(3 055例),强阳性率1.46%(775例);活动性肺结核检出率0.03%(15例)。经过χ2及Logistic逐步回归统计分析,年龄与地区分布是PPD试验强阳性的影响因素(P<0.05)。结论通过PPD初筛,再行胸部X线片及痰涂片检查是在学校及结核病防治门诊发现结核病行之有效的方法。同时,应加强结核病高疫情地区的学校,特别是大专院校学生的结核病筛查力度。

Objective To understand the development situation of the purified protein derivative of tuberculin （PPD） test ,the prevalence of tuberculosis（TB） among the school students in Guangxi and the related influence factors of strong positive result in order to provide the basis for establishing the physical examination system of student TB in Guangxi .Methods The PPD test was conducted in the students participating in the survey firstly ,then the students with strong positive PPD test results and the TB sus-picious symptoms and the suspected TB cases were performed chest X-ray and sputum smear examination .The related factors in the students with strong positive PPD test results and non-strong positive PPD test results were comparatively analyzed .Results To-tally ,53 217 students received the PPD test with the positive rate of 5 .74% （3 055 cases） and the strong positive rate of 1 .46%（775 cases） .The detection rate of active TB was 0 .03% （15 cases） .The χ2 test and the Logistic regression analysis showed that the age group and the regional distribution were the influence factors of strong positive PPD test result （P〈0 .05） .Conclusion The preliminary screening by the PPD test and then conducting chest X-ray and sputum smear examination are the effective method for find TB in school and the TB clinic .At the same time the TB screening should be strengthened in the schools in high epidemic areas of TB ,especially the college students .
