AB Eating  disorders  are  complex  psychiatric  illnesses  characterized  by  pathological  eating  and  related  behaviors,  and  disturbances  in  body  image  that  cause  significant  distress  and/or  impairment.  In  the  United  States,  approximately  30  million  individuals  are  affected  by  an  eating  disorder  in  their  lifetime,  with  prevalence  rates  of  about  1%  for  anorexia  nervosa  (AN),  1.5%  for  bulimia  nervosa  (BN),  and  3%  for  binge  eating  disorder  (BED).  Eating  disorders  that  have  more  recently  been  included  in  Diagnostic  and  Statistical  Manual  of  Mental  Disorders,  Fifth  Edition  (DSM-5)  include  avoidant/restrictive  food  intake  disorder  (ARFID)  and  other  specified  feeding  and  eating  disorders,  including  atypical  AN,  BN,  and  BED  of  insufficient  frequency  and/or  duration,  and  purging  disorder.  Preliminary  estimates  suggest  that  prevalence  rates  are  approximately  5%  for  ARFID,  3%  for  atypical  AN,  4%  for  BN  or  BED  of  insufficient  frequency  and/or  duration,  and  3%  for  purging  disorder.  Eating  disorders  are  more  common  in  women  than  men.  Among  women  in  the  United  States,  the  prevalence  of  AN,  BN,  and  BED  is  similar  across  major  racial/ethnic  groups  (non-Latina  Whites,  Latinas,  Asians,  and  African  Americans).  However,  prevalence  is  higher  in  gay  men  and  transgender  individuals,  with  some  research  suggesting  that  prevalence  is  lower  in  lesbian  women  than  heterosexual  women.
