Abstract: A survey indicated that the prevalence of Demodex infection among 512 college students in Tangshan was 36.3%（186/512）, that of males and females was 39.3%（81/206）and 34.3%（105/306）respectively（P＞0.05）. The infection of Demodex folliculorum accounted for 82.3%（153/186）, followed by D. brevis(7.5%, 14/186）and mixed infection（10.2%, 19/186）. The prevalence was 47.0%（93/198）in subjects with oily skin, 26.6%（37/139）in those with dry skin, and 33.9%（56/165）in mixed-type skin （P＜0.05）. Subjects with facial diseases（62.0%, 75/121）, such as rosacea and acne, were more likely to be infected with Demodex than those with healthy skin （27.6%, 80/290） （P＜0.05）. Prevalence in those lived in humid environment（67.9%, 95/140）was higher than those lived in the desiccating environment （24.5%, 91/372）（P＜0.05）.
