Refining the ideas of "ethnic" skin.

Skin disease occur worldwide, affecting people of all nationalities and all skin types. These diseases may have a genetic component and may manifest differently in specific population groups; however, there has been little study on this aspect. If population-based differences exist, it is reasonable to assume that understanding these differences may optimize treatment. While there is a relative paucity of information about similarities and differences in skin diseases around the world, the knowledge-base is expanding. One challenge in understanding population-based variations is posed by terminology used in the literature: including ethnic skin, Hispanic skin, Asian skin, and skin of color. As will be discussed in this article, we recommend that the first three descriptors are no longer used in dermatology because they refer to nonspecific groups of people. In contrast, "skin of color" may be used - perhaps with further refinements in the future - as a term that relates to skin biology and provides relevant information to dermatologists.

Refining the ideas of "ethnic" skin

Abstract: Skin disease occur worldwide, affecting people of all nationalities and all skin types. These diseases may have a genetic component and may manifest differently in specific population groups; however, there has been little study on this aspect. If population-based differences exist, it is reasonable to assume that understanding these differences may optimize treatment. While there is a relative paucity of information about similarities and differences in skin diseases around the world, the knowledge-base is expanding. One challenge in understanding population-based variations is posed by terminology used in the literature: including ethnic skin, Hispanic skin, Asian skin, and skin of color.

Dissatisfaction and acne vulgaris in male adolescents and associated factors.

BACKGROUND: Acne vulgaris has high prevalence, disturbing quality of life during adolescence. OBJECTIVES: To measure dissastifaction and acne in 18-year-old male individuals and its associated factors. METHODS: A questionnaire was applied by trained interviewers to all boys during selection for the military service. Dissatisfaction and acne was evaluated using a self-administered face scale. Facial, prestrernal and dorsal acne were evaluated separately. RESULTS: A total of 2,200 adolescents, aged 18 years, were interviewed. Among these, 1,678 had acne on the face and 974 (54.05%) showed some degree of dissatisfaction. Regarding the impact of acne located on the chest, 326 out of 686 adolescents (47.52%) reported dissatisfaction. For acne located on the back, 568 out of 1,103 affected individuals (51.50%) showed dissatisfaction. Facial / dorsal acne and dissatisfaction were statistically associated with lower income, lower education levels and with non-whites. Presternal acne and dissatisfaction were statistically asssociated with lower income and lower education levels. CONCLUSION: This population-based study found a high prevalence of acne on the face, back and chest, with high rates of dissatisfaction.

The prevalence of facial acne in Peruvian adolescents and its relation to their ethnicity.

PURPOSE: This article describes the prevalence of facial acne vulgaris in adolescents of Arequipa, Peru, in relation to ethnic characteristics. METHODS: This was a cross-sectional study of 2214 healthy adolescents, 55.83% male and 44.17% female, 12-18 years old. Based on visual inspection, the severity of acne was classified into four grades. The adolescents studied were divided into three ethnic groups: whites, Mestizos, and Indians. RESULTS: Less than half of the adolescents (41.69%) had acne: 33.74% grade 1, 5.19% grade 2, 2.12% grade 3, and 0.63% grade 4. The prevalence of acne varied from 16.33% at 12 years to 71.23% at 17 years. At age 12 and 13 years, the prevalence of acne was higher in females, with the trend reversing over age 14 years. The overall prevalence of acne was significantly less in Indians (27.97%) than in Mestizos (43.08%) or whites (44.47%). More acne was found in postmenarche (39.90%) than in premenarche (20.99%). This trend was also true for the severity of acne. CONCLUSIONS: The prevalence of acne in the adolescents of Arequipa is significantly less than in Caucasians. Peruvian Indians have significantly less acne than Peruvian whites or Mestizos. It seems that ethnicity is an important predictor of not only the prevalence, but also the severity of juvenile acne vulgaris in this sample.
