摘要:
了解石家庄市鹿泉区中小学新生结核病感染情况,探索学校发现和预防肺结核的办法.方法 对鹿泉区2011-2015年51 528名中小学新生进行结核菌素试验(PPD),并分析其肺结核发病情况.结果 BCG-PPD组与TB-PPD组的阳性率及强阳性率差异均有统计学意义(x2值分别为58.424,13.995,P值均<0.05).不同年级学生PPD阳性率及强阳性率间差异有统计学意义(2011-2013年X2值分别为348.501,279.369,2014-2015年x2值分别为203.289,111.693,P值均<0.05).818名强阳性者进一步检查691名(84.47%).发现活动性肺结核高中生4名、初中生2名、无小学生,肺结核检出率为0.73%.420名强阳性者使用“母牛分支杆菌”双向免疫调节剂进行预防.结论 中学生结核分枝杆菌感染不容忽视,应将结核病筛查和结核病健康教育纳入学校的制度化管理.
