A prospective observational study comparing rates of medical instability between adolescents with typical and atypical anorexia nervosa.

Background: Recognition of atypical anorexia nervosa (AAN) has challenged underweight as a defining factor of illness severity in anorexia nervosa (AN). The present study aimed to compare rates of medical instability in adolescents with underweight (AN) and non-underweight (AAN) anorexia nervosa.

Methods: The study examined assessment data from specialist eating disorder services in the UK between January and December 2022.

Greater rate of weight loss predicts paediatric hospital admission in adolescent typical and atypical anorexia nervosa.

Hospital admissions for eating disorders (ED) are rapidly increasing. Limited research exists evidencing the factors that lead to hospital admissions or their outcomes. The current study aimed to identify predictors of hospital admission in adolescents with anorexia nervosa (AN) or atypical anorexia nervosa (AAN).
