Eating disorder symptom severity scale: a new clinician rated measure

Recovery Trajectories in Adolescent Girls with Anorexia Nervosa

Background: This study aimed to document recovery trajectories among adolescents with anorexia nervosa (AN) based on three markers of remission, namely changes in body weight, food restriction, and excessive exercise, and to identify predictors of these trajectories. Methods: One hundred twenty-six adolescent girls (14.7 ± 1.3 years) were recruited during initial assessment visits at specialized eating disorder (ED) programs in five University Health Centers across the province of Quebec, Canada. z-BMI and AN symptom severity (food restriction and excessive exercise) were assessed at initial assessment visits and subsequently reassessed at each quarterly follow-up over a 12-month period to identify recovery trajectories. Results: Considering the three markers of remission, three distinct trajectories emerged: Group 1, rapid responders; Group 2, gradual responders; and Group 3, unstable responders. At initial visits, a difference between groups was found regarding the type of treatment (p = 0.01) and weight suppression (p = 0.02). Group 1 had a higher number of youths hospitalized than Group 2 and Group 3, and a greater weight suppression than Group 3. Furthermore, individuals with atypical AN were more likely to belong to Group 2 than to Group 1 and Group 3 (p < 0.0001). Conclusions: This study contributes to a better understanding of the heterogeneity of recovery trajectories in adolescent girls with AN.

Characteristics and clinical trajectories of patients meeting criteria for avoidant/restrictive food intake disorder that are subsequently reclassified as anorexia nervosa

OBJECTIVE

To examine the initial assessment profiles and early treatment trajectories of youth meeting the criteria for avoidant/restrictive food intake disorder (ARFID) that were subsequently reclassified as anorexia nervosa (AN).

METHOD

A retrospective cohort study of patients assessed and treated in a tertiary care eating disorders (ED) program was completed.

RESULTS

Of the 77 included patients initially meeting criteria for ARFID, six were reclassified as having AN (7.8%) at a median rate of 71 days after the first assessment. Patients in this cohort presented at very low % treatment goal weight (median 71.6%), self-reported abbreviated length of illness (median 6 months), and exhibited low resting heart rates (median 46 beats per minute). Nutrition and feeding focused worries related more to general health as opposed to specific weight and shape concerns or fears at assessment in half of those reclassified with AN. Treatment at the 6-month mark varied among patients, but comprised family and individual therapy, as well as prescription of psychotropic medication.

CONCLUSION

Prospective longitudinal research that utilizes ARFID-specific as well as traditional eating disorder diagnostic measures is required to better understand how patients with restrictive eating disorders that deny fear of weight gain can be differentiated and best treated.
