Summary
Skin pigmentation significantly changes with age in Basque boys aged 8-19 years. This study analyzed skin color variations using reflectance spectrophotometry, comparing results with a Welsh population.
Area of Science:
- Anthropometry
- Human Biology
- Dermatology
Background:
- Skin color is a complex trait influenced by genetics and environment.
- Understanding age-related skin changes is crucial for various biological and medical fields.
- Previous studies have explored skin pigmentation variations across different populations.
Purpose of the Study:
- To analyze age-related variations in skin color among Basque boys.
- To investigate the influence of measurement timing on skin reflectance.
- To compare findings with a similar study conducted in Wales.
Main Methods:
- A cross-sectional study involving 796 Basque boys aged 8 to 19 years.
- Skin reflectance measurements were taken on the upper inner arm and forehead.
- An EEL DS29 Digital Unigalvo reflectance spectrophotometer with a nine-filter head was utilized.
Main Results:
- Statistically significant ontogenic changes in skin pigmentation were observed.
- The month of measurement showed a discernible influence on reflectance values.
- Comparisons with data from a Pembrokeshire, Wales population were performed.
Conclusions:
- Skin pigmentation undergoes significant developmental changes during adolescence in males.
- Environmental factors, such as seasonal variations indicated by measurement month, can impact skin reflectance.
- Cross-population comparisons highlight potential regional differences in skin color development.
