目的了解内蒙古医科大学学生面部蠕形螨感染情况。方法 2015年9月至2016年1月,以该校2013级临床医学本科学生为调查对象,采用透明胶纸法对学生面部蠕形螨进行取样,同时就皮肤性质、面部皮损、洁面方式、民族等相关因素进行问卷调查。结果共调查434名学生,该人群总感染率为38.71%。168例蠕形螨感染者中,以单纯毛囊蠕形螨感染居多,占77.38%,额头检出率最高,占52.38%,Ⅰ度感染占80.36%,表明大多数为轻度感染。有面部皮损患者(46.11%)的感染率高于无面部皮损(34.08%)的人员,且有统计学方面的意义(P<0.05)。蠕形螨感染与性别、皮肤性质、洁面方式、民族(汉、蒙)等无关。结论内蒙古医科大学学生面部蠕形螨感染率高于全国平均水平,应针对性地进行预防和治疗。
