摘　　要：目的为了解本校医学生蠕形螨感染情况,探讨蠕形螨感染的相关因素,为蠕形螨的预防提供科学的依据。方法用透明胶纸粘贴过夜法对学生进行蠕形螨感染调查,同时对他们进行基本情况、生源地、脸部皮肤性质、脸部皮肤疾患状况、卫生习惯的问卷调查。结果蠕形螨总感染率为18.97%(77/406),男生、女生感染率分别为20.43%(47/230)和17.05%(30/176),两者差异无统计学意义(χ2=0.75,P>0.05)。城市学生感染率为15.60%(22/141),农村学生感染率为20.75%(55/265),两者差异无统计学意义(χ2=1.59,P>0.05)。脸部皮肤性状油性者感染率为24.75%(49/198),中性者感染率为15.00%(21/140),干性者感染率为10.29%(7/68),不同皮肤性状者蠕形螨感染率差异有统计学意义(χ2=9.05,P<0.01)。脸部皮肤正常者181人,蠕形螨感染阳性23人,感染率为12.71%(23/181),有脸部皮肤疾病者感染率为24.00%(54/225),两者差异有统计学意义(χ2=8.32,P<0.01)。常与他人混用洗具者感染率为29.23%(19/65),不与他人混用洗具者感染率为17.01%(58/341),两者差异有统计学意义(χ2=5.31,P<0.05)。常用肥皂或洗脸液洗脸者感染率为16.29%(43/264),不用或很少用肥皂或洗脸液洗脸者,感染率为23.94%(34/142),两者差异无统计学意义(χ2=3.52,P>0.05)。结论蠕形螨的感染与脸部皮肤性状、脸部皮肤疾病、卫生习惯密切相关,学生应该科学保养皮肤、改变不良卫生习惯。Objective The study aimed to assess the prevalence of demodex infection among medical students of our University and explore the relevant factors for the infection, so to provide a scientific reference for the prevention of demodex. Methods Cellophane tape impressions were used to determine the presence of demodex infection among the students. The students were also surveyed by a questionnaire inquiring about their general information, place of birth or origin, facial skin type, facial skin problems, and hygiene habits. Results The overall positive rate of demodex infection was 18.97% （77/406）, with 20.43% （47/230） and 17.05% （30/176） a- mong male and female students, respectively; no significant gender difference was observed （%2=0.75, P〉0.05）. The infection rates a- mong students from urban areas and those from rural areas were 15.60% （22/141） and 20.75% （55/265）, respectively; the difference was not statistically significant （X2=1.59, P〉0.05）. The infection rates among students with oily, neutral, or dry facial skin type was 24.75% （49/198）, 15.00% （21/140）, and 10.29% （7/68）, respectively, suggesting that positive rate of demodex infection significantly varied among students with different facial skin types （X2=9.05, P〈0.O1）. Among the 181 students with normal facial skin, 23 stu- dents were tested demodex-positive, resulting in a positive rate of 12.71% （23/181） ; on the other hand, the infection rate among students with facial skin problems was 24.00% （54/225）, indicating a statistically significant difference between the two groups （%2--8.32, P〈0.01）. The infection rates among students who frequently use or have never used shared toiletries were 29.23% （19/65） and 17.01% （58/341）, respectively; the difference was statistically significant （X2=5.31, P〈0.01）. The infection rates among students who regularly wash their face with soap or facial cleansers and those who never or seldom do so were 16.29% （43/264） and 23.94% （34/14
