不同行业人群中肺螨病流行情况的调查研究

目的 调查不同行业人群中肺螨病的流行特征。方法 询问病史、螨渗液皮试及对螨渗液皮试阳性者进行痰检。结果 对1409人作螨渗液皮试,皮试阳性429人,阳性率30.45％;对皮试阳性或有明显呼吸道症状的457人痰检,痰螨阳性107例,检出率为23.41％,总患病率7.59％(107/1409)。检出的螨经鉴定分5科10属12种。农村磨坊人员患病率为14.10％,其次为面粉厂11.11％,粮库8.28％等。患病率随工作年限及年龄的增加而上升;性别间患病差别无显著性。结论 肺螨病流行与职业有密切关系,工作年限越长,工龄越长,患病率越高。对特定人群要加强个人劳动保护。
