阜阳市某高职大学生蠕形螨感染情况调查

A survey on prevalence of demodex infection in vocational college students in fuyang city

目的了解安徽省阜阳职业技术学院在校大学生蠕形螨感染情况,分析蠕形螨感染的影响因素。方法以安徽省阜阳职业技术学院大一、大二学生为研究对象,采用随机抽样的方法 ,对442名在校高职大学生通过透明胶纸粘贴法进行蠕形螨检查,同时对调查对象的个人习惯、洁面方式、皮肤类型、面部疾患等方面进行问卷调查。结果以阜阳市某职业技术学院442名在校大学生为调查对象,蠕形螨感染者为86人,总感染率为19.46%(86/442),单纯毛囊蠕形螨感染占82.56%(71/86),高于单纯皮脂蠕形螨感染及混合感染;面颊部位感染率23.26%(20/86)较鼻部感染率高;面部有疾患者如痤疮、皮炎、毛囊炎等感染率25.70%(55/214),高于面部正常者;油性皮肤学生感染率为27.94%(38/136),高于混合性皮肤及干性皮肤学生;在调查季节方面夏季感染率为26.57%(38/143),高于冬季感染率;在感染程度方面,轻度面部蠕形螨感染率高达82.56%,经χ2检验分析,显示季节、皮肤类型、面部疾患为蠕形螨感染的影响因素,多因素非条件logistic回归分析,面部疾患为蠕形螨感染的危险因素。结论安徽省阜阳职业技术学院大学生蠕形螨感染较为普遍,以毛囊蠕形螨感染为主,多为轻度感染,男女生蠕形螨感染率无显著差异,其感染率与皮肤性质、面部疾患、季节温度有关。

Objective To investigate the prevalence of demodex infection in vocational college students in Fuyang city, and study the influencing factors of demodex infection. Methods A random sample survey of demodex infection rate among 442 freshman and sophomore in Fuyang vocational college was carried out. Demodex was examined by using the cellophane tape method（CTP）. A questionnaire on their daily personal habits, facial cleansing, skin type and facial skin disease was performed simultaneously. Results 86 students were with demodex infection with a total infection rate of 19.46% （86/442） ;the rate of simple infection of Demodex foliiculorum was 82.56% （71/86） , which was higher than that of simple infection of Demodex brevis and multi-infection. The rate of cheeks infection was 23.26% （ 20/86 ）, which was higher than that of nasal infection. The infection rate in patients with facial skin diseases, such as aene, dermatitis and follieulitis,was 25.70% （55/214） ,which was higher than that of subjects without facial skin diseases. The infection rate of students with oily skin was 27.94% （38/136） ,which was higher than that of individuals with mix skin or dry skin. The infection rate in summer was 26.57% （38/143）, which was higher than that in winter. The rate of mild facial demodex in- fection was up to 82.56% in terms of the degree of infection The chi square test showed that season, skin type and facial skin disorders were the contributory factors. The multivariate unconditional logistic regression result showed that facial skin disorders were the risk factors of demodex infection. Conclusion Facial demodex infection is more common in vocational college students. The mild infection caused by Demodex follieulorum is common. There is no difference between girls and boys. The infection rate is positive related with the type of skin, facial skin disorders and seasonal temperature.
