Abstract excerpt

OBJECTIVE: Avoidant/restrictive food intake disorder (ARFID) is an eating disorder characterized by persistent avoidant/restrictive eating unrelated to body image. Sex differences in clinical phenotypes and neurobiology of ARFID are understudied. We hypothesized that females with ARFID would have a greater frequency of the lack of interest and fear of aversive consequences phenotypes, higher levels of...
