1992年7月至1993年1月于江苏地区用病例对照研究的方法着重对尘螨暴露、尘螨过敏与外源性哮喘的联系进行非条件Logistic回归分析。以对象床褥上鸟嘌呤含量为尘螨暴露水平的指标,血清中尘螨特异性IgE为尘螨过敏的指标。结果表明:尘螨暴露、尘螨过敏、双亲过敏史和出生于高螨密度月份均与外源性哮喘发生有显著联系。尘螨暴露的人群归因危险度百分比(PAR%)达70.29%。据此,对外源性哮喘的防治提出了建议。
July 1992 to January 1993 in Jiangsu Province with case-control study focused on dust mite exposure, dust mite allergy and extrinsic asthma were non-conditional Logistic regression analysis. The object of bedding guanine content for the dust mite exposure level indicators, dust-mite specific IgE serum dust mite allergy indicators. The results showed that dust dust mite exposure, dust mite allergy, the history of parents and parents were born in high mite density month were significantly associated with exogenous asthma. Dust mites exposed to the percentage of attributable attribution risk (PAR%) of 70.29%. Accordingly, the prevention and treatment of exogenous asthma made recommendations.
