TLDR Adolescent girls with anorexia nervosa have lower hair cortisol levels than healthy and psychiatric peers.
The study analyzed hair cortisol concentration (HCC) as a long-term marker of cortisol secretion in 22 female adolescent inpatients with anorexia nervosa (AN), compared to 20 healthy controls (HC) and 117 psychiatric controls (PC). Results showed that HCC was lower in AN patients compared to HC, with a significant correlation between HCC and body mass index (BMI) but not age. The findings suggested that HCC might reflect BMI-related changes rather than specific endocrine alterations due to AN. Additionally, the incorporation of cortisol into hair might be affected by hair follicle disturbances in AN patients.
