Serum 25-hydroxyvitamin D and adult-onset atopic dermatitis: insights from two large national cohorts

Key Points

• To investigate the relationship between serum 25-hydroxyvitamin D levels and the risk of developing adult-onset atopic dermatitis.
• Utilized data from two large national cohorts.
• Measured serum 25-hydroxyvitamin D levels of participants.
• Analyzed data to determine incidence rates of adult-onset atopic dermatitis.
• Identified rising incidence rates of adult-onset atopic dermatitis.
• Found associations suggesting lower vitamin D levels may relate to higher incidences of AOAD.
