摘　　要：目的探讨气候因素对粉尘螨皮试结果的影响。方法应用阿罗格粉尘螨皮肤点刺液对崇明岛2005年1月至2008年12月290例过敏性疾病患儿进行检测。记录当地的每日平均气温和相对湿度。分析不同月份、不同季节皮试前1个月的平均温度与湿度下粉尘螨皮试阳性率的差异。结果290例过敏性疾病患儿粉尘螨皮试总阳性率达81.7%,以哮喘合并鼻炎患儿为高。不同月份及不同季度粉尘螨皮试阳性率有差异,以7～11月份及夏秋季皮试阳性率为高,差异具有统计学意义。皮试前1个月平均温度在18℃以上及平均湿度在70%以上时阳性率更高,差异均具有统计学意义。结论崇明岛过敏性疾病患儿粉尘螨皮试阳性率高,不同月份及季节粉尘螨皮试阳性率有差异,皮试前1个月平均温度及湿度不同粉尘螨皮试结果也有差异。温度、湿度等气候因素可能对粉尘螨皮试结果有影响。Objective To explore the relation between climatic factor and dermatophagoides farinae positive rate of skin prick tests（SPT） on Chongming island. Methods The 290 children patient who were diagnosed with allergic diseases were examined by skin prick tests（SPT） with dermatophagoides farinae provided by Allergopharm Corporation from January 2005 to December 2008 on Chongming island, at the same time the climatic data were collected every day. The positive rate of dermatophagoides farinae examined by skin prick tests （SPT） of different months and seasons , different monthly average air temperature and relative humidity before skin prick tests were analyzed.The data were analyzed by SPSS15.0. Results The general dermatophagoides farinae positive rate of 290 children with allergic diseases was 81.7% （238/290）, and the positive rate of children with asthma and allergic rhinitis was higher than the others （X^2= 21.51, P = 0.000）. The positive rate of dermatophagoides farinae of different months and seasons were different. The positive rate from July to November, both summer and autumn,was higher than the others （Z = 2.789,P = 0.005 and x2= 11.959, P = 0.008）.When the monthly average air temperature exceeded 18℃ and the monthly average relative humidity surpassed 70%; the positive rate of dermatophagoides farinae was higher than the others（X^2= 6.643,P = 0.036 and X^2= 5.138 ,P = 0.023 ）. All of the differences were significant. Conclusion The general dermatophagoides farinae positive rate of SPT with allergic diseases is 81.7% on Chongming Island. The positive rate of dermatophagoides farinae of different months and seasons are different. The dennatophagoides farinae positive rate of SPT under different monthly average air temperature and relative humidity are different too. The climatic factor, such as air temperature and relative humidity, may impact the results on SPT of dermatophagoides farinae.
