目的掌握漯河市中小学新生结核病免疫现状,为做好新生结核病防治工作提供依据。方法漯河市4所市直小学,10所市直初中,6所市直高中共13 847人进行结核菌素(PPD)试验。结果漯河市小学新生PPD阳性率为36.76%,初中新生PPD阳性率为56.24%,高中新生PPD阳性率为54.83%,差异有统计学意义(P<0.05)。小学新生强阳性率为3.19%,初中新生强阳性率为5.18%,高中新生强阳性率为3.90%,差异有统计学意义(P<0.05)。中小学新生中,男生强阳性率4.97%,女生强阳性率3.41%,差异有统计学意义(P<0.05)。结论漯河市初、高中新生阳性率较高,初中新生强阳性率较高,男生的强阳性率比女生高。由结核病感染率可知漯河市中小学新生对结核菌有一定抵抗力,但PPD试验强阳性仍较高,结核病防治工作不容乐观,需制定更加详细的结核病防控计划。
Objective To master the status quo of tuberculosis immunization among primary and secondary freshmen in Luohe City and provide the basis for the prevention and treatment of newborn tuberculosis. Methods Totally 13 847 people from 4 primary schools, 4 middle schools and 6 middle schools in Luohe City were enrolled in the tuberculin (PPD) test. Results The positive rate of PPD in primary school freshmen was 36.76%, the positive rate of PPD in junior high school was 56.24%, and the positive rate of PPD in high school freshmen was 54.83%. The difference was statistically significant (P <0.05). The strong positive rate of primary freshmen was 3.19%, the positive rate of junior high school freshmen was 5.18%, and the strong positive rate of freshmen was 3.90%, the difference was statistically significant (P <0.05). Primary and secondary freshmen, male strong positive rate of 4.97%, female strong positive rate of 3.41%, the difference was statistically significant (P <0.05). Conclusions The positive rate of neonatal freshmen and high school freshmen in Luohe City is high, the positive rate of freshmen in junior high school is higher, and that of male students is higher than that of female students. From the TB infection rate we can see that primary and secondary freshmen have a certain resistance to TB in Luohe City, but the strong positive PPD test is still high. The prevention and treatment of tuberculosis is not optimistic and a more detailed TB prevention and control plan needs to be formulated.
