초장수인의 피부 특징 및 피부질환의 빈도에 대한 연구

Abstract

The increased aging of the population in the developed world is an accepted fact. Consequently, the number of patients aged 90 years or above (super-old age: from 90 to 99), and centenarians (above 100) will increase in the coming years. The objective was to determine the prevalence and characteristics of skin diseases in the population of super-old ages and centenarians. A total of 50 volunteers, aged from 90 to 106 years, were enrolled on this study. They completed a questionnaire about skin diseases and underwent a cutaneous examination during the period of July 26 to 30, and Aug 23 to 28, 2004. The average age of the volunteers was 96.3 years. 28 volunteers were women and 22 were men. The common diseases were found to be senile lentigo, seborrheic keratosis, idiopathic guttate hypomelanosis, xerosis, telangiectasia, onychomycosis, tinea pedis, and cherry hemangioma. Wrinkle grading of men was less severe than in women. The degree of pigmentation was independent of age and sex. However, activity and pigmentation scale showed a significant statistical correlation. Gray hair and alopecia in men was more severe than in women. As for aging factors, smoking, activity, location, and occupation did not appear to play an important role in wrinkle formation. The incidence of skin disorders increased with age, due to changes in skin structure and lifelong exposure to environmental aggravations. Super-old aged people often have many skin diseases. However, only a small number of volunteers were included in this study. Therefore, further dermatologic studies need to be conducted.
