"Study Suggests Morning Chronotypes May Have Increased Anorexia Risk"

A study led by Massachusetts General Hospital and collaborators has found that individuals with anorexia nervosa are more likely to be early risers, a trait contrasting with other mental disorders that are linked to evening chronotypes. Utilizing genetic analysis, the researchers identified a bidirectional association between anorexia nervosa and morning chronotype genes, as well as a connection with increased insomnia risk. These insights could inform new circadian-based prevention and treatment strategies for anorexia nervosa, which has a high mortality rate among psychiatric disorders.
