Analysis of tuberculin test results of freshmen enrolled in high school and boarding junior middle school in Huacao Town of Minhang District

目的本研究分析上海市闵行区华漕镇高中及寄宿制初中入学新生结核病感染及发病情况,为学校结核病防控工作提供科学依据。方法对2018学年华漕镇高中及寄宿制初中入学新生进行结核菌素(PPD)试验,对PPD试验强阳性学生转诊到医疗机构开展胸部X射线检查,对试验结果进行统计学分析。结果638名入学新生PPD试验阳性率为21.94%,其中强阳性率为1.41%。公立学校学生阳性率为24.40%,私立学校学生阳性率为19.21%,差异无统计学意义,P>0.05。男生阳性率为19.54%,女生阳性率为24.17%,差异无统计学意义,P>0.05。六年级学生阳性率为19.59%,高一年级学生阳性率为26.96%,差异有统计学意义,χ2=4.41,P=0.036。结论采用PPD试验有助于了解新生结核病感染情况,及时采取有效的防控措施,防止结核病在校园内传播,从而阻断学校发生聚集性结核病疫情。

Objective This study analyzed the tuberculosis infection and incidence of high school and boarding junior high school freshmen in Huacao Town,Minhang District,Shanghai,and provided a scientific basis for school tuberculosis prevention and control.Methods Conducted a tuberculosis(purified protein derivative,PPD)test for the new students enrolled in Huacao Town High School and boarding junior high school in the 2018 school year.Referred to the medical institution for a chest X-ray examination of students with strong positive PPD test,and statistically analyzed the test results.Results The positive rate of PPD test for 638 freshmen was 21.94%,of which the strong positive rate was 1.41%.The positive rate of students in public schools was 24.40%,and the positive rate of students in private schools was 19.21%,the difference was not statistically significant,P>0.05.The positive rate of male students was 19.54%,and the positive rate of female students was 24.17%,the difference was not statistically significant,P>0.05.The positive rate of sixth grade students was 19.59%,and the positive rate of high grade students was 26.96%.The difference was statistically significant,χ2=4.41,P=0.036.Conclusion The use of the PPD test helps to understand the status of new tuberculosis infections,and takes effective prevention and control measures in a timely manner to prevent the spread of tuberculosis on campus,thereby blocking the occurrence of clustered tuberculosis outbreaks in schools.
