We have determined skin phototype by a self-reporting questionnaire proposed by Fitzpatrick in 128 Korean medical students. We also measured the minimal erythema dose (MED), minimal melanogenic dose and investigated their relationship to phototype. A questionnaire of skin phototypes revealed that 13.3% of the students are skin phototypes I and II. Based on MEDs, we demonstrated that 14.8% of the students fall into the UV-sensitive group as defined by an MED of less than 40 mJ/cm2, which is the upper range of MED of phototypes I and II in a white population. The skin phototypes did not show a positive correlation to MEDs and only 2.3% of students classified as skin phototypes I and II showed an MED below 40 mJ/cm2. This study indicates that the skin phototyping method proposed by Fitzpatrick does not reliably predict UV-sensitive individuals within the Korean population.
我们通过Fitzpatrick提出的自我报告问卷，对128名韩国医科学生进行了皮肤光型测定。我们还测量了最小红斑量（MED）、最小致黑量，并研究了它们与光型的关系。一份皮肤光型问卷显示，13.3%的学生属于皮肤光型I和II。基于最小红斑量，我们证明，按照小于40 mJ/cm²的最小红斑量定义，14.8%的学生属于紫外线敏感组，这是白种人群中光型I和II最小红斑量的上限范围。皮肤光型与最小红斑量之间未显示出正相关，在被归类为皮肤光型I和II的学生中，只有2.3%的学生最小红斑量低于40 mJ/cm²。这项研究表明，Fitzpatrick提出的皮肤光型测定方法不能可靠地预测韩国人群中的紫外线敏感个体。
