138所中小学校入学新生结核病筛查情况

Tuberculosis screening results of freshmen in 138 primary and secondary schools

目的了解北京市西城区中小学入学新生结核感染及患病情况,为学校结核病控制工作提供参考依据。方法对2018年西城区中小学入学新生开展结核病筛查。所有学生均进行肺结核密切接触史和肺结核可疑症状调查,对全部高中生和住宿初中生以及有肺结核密切接触史或肺结核可疑症状的小学生和非住宿初中生开展结核菌素皮肤试验(PPD试验),对PPD试验强阳性者或有肺结核可疑症状者进行X线胸片检查。结果 138所学校的35 437名新生完成了肺结核可疑症状及接触史调查,6 111人进行了PPD试验,163人进行了胸部X线检查,未发现活动性肺结核患者。其中PPD阳性955人,阳性率15.63%(955/6 111)。在进行PPD试验的学生中,小学组的PPD阳性率为14.28%(1/7),初中组的PPD阳性率为19.94%(64/321),高中组的PPD阳性率为15.39%(890/5 783);结核感染者458人,结核感染比例为7.49%(458/6 111),其中小学组未发现结核感染者,初中组的结核感染比例为10.28%(33/321),高中组的结核感染比例为7.35%(425/5 783);PPD强阳性158人,PPD强阳性率2.59%(158/6 111),小学组未发现PPD强阳性者,初中组的PPD强阳性率为1.87%(6/321),高中组的PPD强阳性率为2.63%(152/5 783);PPD阳性率、强阳性率、结核感染比例各组间差异无统计学意义(P> 0.05)。结论开展入学新生结核病筛查可以及早发现结核感染者,是落实学校结核病防控工作的重要措施。

Objective To know the the conditions of tuberculosis infection and the prevalence of tuberculosis in primary and secondary schools freshmen in Beijing Xicheng District,and to provide reference for tuberculosis control in schools.Methods We conducted the screening for tuberculosis for primary and secondary school freshmen in Xicheng District in 2018.All students were investigated questionnaires on suspicious symptoms of tuberculosis and history of exposure to tuberculosis.The non-boarding middle school students and pupils with suspicious symptoms or history of exposure were examined with PPD test.The boarding middle school students and all high school students were also examined with PPD test.The students with strong positive results or suspicious symptoms were checked with chest X-ray.Results Totally 35 437 students in 138 primary and secondary schools were investigated,6 111 students were examined with PPD test,163 students were further examined with chest X-ray.No active tuberculosis patient was found.The positive rate of PPD test was 15.63%(955/6 111).The positive rates in primary,middle and high school groups whose students were examined with PPD test were respectively 14.28%(1/7),19.94%(64/321),15.39%(890/5 783).The tuberculosis infection accounted for 7.49%(458/6 111).No tuberculosis infected student was found in primary school group.The tuberculosis infection in middle and high school groups respectively accounted for 10.28%(33/321),7.35%(425/5 783).The strong positive rate was 2.59%(158/6 111).No strong positive student was found in primary school group.The strong positive rates in middle and high school groups were respectively 1.87%(6/321),2.63%(152/5 783).There is no statistically significant of PPD positive rate,strong positive rate,and tuberculosis infection rate in groups(P>0.05).Conclusion Screening for tuberculosis for primary and secondary school freshmen can find potential tuberculosis infected person early.It is an important tuberculosis control measure in schools.
