目的 了解不同年级、不同性别及不同民族学生 ,在校集体生活期间人体蠕形螨感染率的差异。 方法 用透明胶带法检查两侧鼻沟处寄生的蠕形螨。 结果 2 2 48名学生的感染率为 5 1.5 %。其中 ,一年级感染率为 42 .6 % ,二年级为 49.6 % ,三年级为 6 6 .8% ;男性感染率为 5 5 .7% ,女性为 48.7% ;蒙古族感染率为49.8% ,汉族为 5 2 .8% ,其他民族为 6 4.3%。 结论 高年级感染率明显高于低年级感染率 (P<0 .0 1) ,男性高于女性 (P<0 .0 1) ,汉族略高于蒙古族 ,但无显著性差异。

Objective To understand the difference of Demodex prevalence among medical students living and studying together with different classes, sexes and nationalities. \ Methods\ Demodex folliculorum and Demodex brevis were detected by using cellophane tape on the nasolabial grooves. \ Results\ The overall prevalence was 51\^5% in 2 248 medical students. Prevalence in different classes and sexes was: freshman 42\^6%, sophomore 49\^6% and third year students 66\^8%; 55\^7% in males and 48\^7% in females. Prevalence in students with different nationalities was: Mongolian 49\^8%, Han 52\^8% and other minorities 64\^3%. \ Conclusion\ The Demodex prevalence in students of senior classes was higher than those from junior ones (P<0\^01), higher in males than in females (P<0\^01). Prevalence in Han students was slightly higher than in Mongolian with no statistical difference.
