农村老年人群呼吸道症状与肺结核病检出率

目的：探讨农村老年人群呼吸道症状与肺结核病检出的关系。方法：采取整群随机抽样方法，对本市农村地区老年人群进行结核病流行病学抽样调查。结果：受检人群呼吸道症状率为13．7％，其中男性为16．8％，女性为11．6％。人群X线异影率为2．89％，而有可疑症状者的异影检出率为5．5％。流调新发现病人可疑症状率仅为64．14％，39．86％的活动性病人，33．3％菌阳病人在发现之前并未有明显的症状。男性人群有症状者中新发现活动性肺结核病人检出率为8．33‰，菌阳检出率为2．21‰。结论：农村老年人群因症就诊被动发现工作效果较差。有必要经常持久地开展针对此重点人群的主动发现工作。
