원저 : 한국 청년층의 UVB에 의한 최소홍반량에 따른 광피부형의 분류

Background: We predicted that t.he self reporting questionnaire proposed by Fitzpatrick might not be appropriate for classifyin~v; the skin phoiotype in Korean people. Objective : We classified the skin phototypes in Korean people by measuring the minimal erythema dose (MED) of UVB on t.he basis of MEDs of skin type proposed by Pathak and Fitzpatrick. Methods : Two hundred and eighty-four male Korean rnedical students participated in this study. We irradiated UVB with Waldmann UV 800 and measured MEDs after 24 hours. Results : The mean MED was 70.1+21.3 mJ/cm2. Most of the MEDs were 70, 60, 50 mJ/cm in the order of frequency. On the basis of the skin type proposed by Pathak and Fitzpatrick, the most frequent phototype was the skin type V(56.3%) by MED. 20.8% and 13.8% of the subjects eorresponded to the skin types UV and III, respectively. 9.1% of the subjects fell into the UV sensitive group, skin type l and II. Conclusion : Using these results as groundwork, simple and precisely applicable classification of skin phototype in Korean people needs to be established. (Kor J Dermatol 1996;34(6): 893-897)
