摘　　要：目的调查某医学院校新生油性皮肤者面部人体蠕形螨的感染情况,并分析人体蠕形螨感染的影响因素,为特定人群蠕形螨的防治提供依据。方法对部分新生进行问卷调查,并对油性皮肤者面部蠕形螨的感染进行检查,采用透明胶带粘贴过夜法查螨虫。胶带置于光镜下检查,阳性片计数虫数并进行虫种鉴定。结果共调查804名学生,其中油性皮肤者308名,占38.3%。油性皮肤者面部蠕形螨感染情况如下,总感染率为34.4%(106/308),单纯毛囊蠕形螨感染占50.9%(54/106),单纯皮脂蠕形螨感染占20.8%(22/106),二者差异有统计学意义(χ2=21.0,P<0.01),混合感染占28.3%(30/106)。轻度感染占94.3%(100/106)。鼻侧感染54.7%(58/106)较额部47.1%(50/106)、鼻尖35.8%(38/106)高,前二者与鼻尖差异有统计学意义(χ2=7.61,P<0.01)。结论该校新生油性皮肤者人体蠕形螨普遍,但以轻度感染为主,毛囊蠕形螨感染高于皮脂蠕形螨,感染以鼻侧、额部为主,感染与生活习惯有关。Aim To survey the current status of Demodex infections in Xingtai Medical College students with oily skin.Methods Transparent adhesive tape was used for survey of Demodex infection in students of Xintai Medical College.Results A total of 804 students were surveyed and 306 students were with oily skin,accounted for 38.3%.The total infection rate of Demodex was 34.4%（106/308）.The infection of Demodex folliculorum accounted for 50.9%（54/ 106） was higher than that of Demodex brevis（20.8%,22/106）（P0.01,）and mixed infection occupied 28.3%（30/106）.Conclusion Demodex folliculorum and Demodex brevis infection predominated in students and preventive and control measures be taken.
