title: Should non-fat-phobic anorexia nervosa be included in DSM-V?
abstract: OBJECTIVE
  Cross-cultural data suggest that rationales for food refusal vary in anorexia nervosa (AN), and a variant, termed non-fat-phobic AN (NFP-AN), has been described. This review evaluates whether data support modification of the requirement for intense fear of weight gain to meet AN criterion B in DSM-V.
  
  
  METHODS
  We performed a systematic search of the Medline and PsychInfo literature and evaluated the relevant publications by Robins and Guze's (Am J Psychiatry 126, 983-987, 1970) criteria as a standard for diagnostic validity. We also performed a meta-analysis comparing the severity of eating pathology in AN to (a) NFP-AN and (b) AN with low drive for thinness (low-DT-AN).
  
  
  RESULTS
  A modest literature indicates that NFP-AN has wide geographic distribution and occurs in both Western and non-Western populations alongside cases of typical AN. Aggregating across eligible studies, patients with NFP-AN or low-DT-AN score at least 2/3 of a standard deviation lower on measures of eating pathology than patients with conventional AN. Transcultural comparison of drive for thinness suggests significantly lower norms in non-Western cultures.
  
  
  CONCLUSIONS
  NFP-AN occurs with wide distribution. Further research is necessary on the course and outcomes of NFP-AN to characterize its congruence with, or distinction from, conventional AN. We discuss several options for including a description of NFP-AN in DSM-V.
