目的了解沧州市某县初中在校学生结核病发病情况,以控制结核病在学校传播流行。方法选择该县初中学校在校的1 900名学生进行结核菌素(PPD)试验筛检。结果在1 900名学生中,PPD试验阳性率为13.74%,其中一般阳性率为9.74%,强阳性率为4.00%。一般阳性者男女生差异无统计学意义(χ2=0.014,P>0.05),强阳性者男女生之间差异亦无统计学意义(χ2=1.18,P>0.05)。肺结核患病率为2.65‰,男女生差异亦无统计学意义(χ2=0.31,P>0.05)。结论应加强对PPD试验阳性者的监督、管理和治疗,定期开展结核病的筛检,减少结核病在学校中的发生与传播;另外,在学校中应加强结核病知识的宣传教育。
Objective To understand the incidence of tuberculosis in junior high school students in a county in Cangzhou to control the prevalence of tuberculosis in schools. Methods A total of 1 900 students in the county junior high school were enrolled in the screening test for tuberculin (PPD). Results Among 1 900 students, the positive rate of PPD was 13.74%, with a positive rate of 9.74% and a strong positive rate of 4.00%. There was no significant difference between male and female who were generally positive (χ2 = 0.014, P> 0.05). There was also no significant difference between male and female with strong positive (χ2 = 1.18, P> 0.05). The prevalence of tuberculosis was 2.65 ‰, and there was no significant difference between boys and girls (χ2 = 0.31, P> 0.05). Conclusion The surveillance, management and treatment of PPD positive patients should be strengthened. The TB screening should be regularly carried out to reduce the occurrence and spread of tuberculosis in schools. In addition, the publicity and education on TB knowledge should be strengthened in schools.
