面部蠕形螨感染与饮食习惯关系的研究

Study on Relationship Between Facial Demodex Infections and Dietary Habits

目的了解饮食习惯与蠕形螨感染的关系。方法以本科医学生为研究对象,采用透明胶纸挤粘法采集鼻唇沟及鼻尖部位蠕形螨,显微镜下检测虫体,发现成虫、幼虫或者虫卵均为阳性。结果 254名学生蠕形螨总感染率为18.50%,其中单一毛囊蠕形螨感染率为14.96%,占总感染数的80.85%;单一皮脂蠕形螨感染率为2.36%,占总感染数的12.77%;两种蠕形螨混合感染率为1.18%,占总感染数的6.38%。农村学生感染率为20.70%,城市学生感染率为10.71%,城市与农村学生感染率差异无统计学意义(P>0.05)。喜欢食用咸香辛辣食物者感染率为16.92%,不喜欢食用咸香辛辣食物者感染率为20.16%,两种饮食习惯者感染率差异无统计学意义(P>0.05)。结论人面部蠕形螨感染虫种主要是毛囊蠕形螨,蠕形螨感染与饮食习惯无关。
