Basic Study on Transepidermal Water Loss (TEWL) of infants living in urban and non-urban areas and their environmental factors

Satomi Ono, Yukiko Manabe

The aim of this study is to document Transepidermal water loss (TEWL) in infants living in urban and non- urban areas as well as individual and environmental factors, and to search for any distinguishing features and correlations. A significant difference was observed in trans epidermal water loss in children residing in a region located outside a large city or urban area, and a significant difference was observed also in cuticle water content measured at the same time. It was clear that infants living in an administrative district outside of an urban area retained more water in their cuticles than infants residing in a large city, and transpired more water through the epidermis. It was suggested that TEWL in preschool children may differ according to age and gender, and is influenced by outdoor humidity, outdoor temperature, surface temperature, and cuticle water content.
