The Impact of DSM-5 on Eating Disorder Diagnoses. International journal of eating disorders Vo, M., Accurso, E. C., Goldschmidt, A. B., Le Grange, D. 2017; 50 (5): 578-581


Eating disorder diagnostic criteria were revised from the fourth to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV and -5, respectively). This study examines the impact of these revisions on rates of eating disorder diagnoses in treatment-seeking youth.Participants were 651 youth, ages 7-18 years, presenting to an outpatient eating disorders program who met criteria for a DSM-IV eating disorder diagnosis on intake. Patients completed well-validated semi-structured interviews to assess eating disorder psychopathology and psychiatric comorbidity.Participants were predominantly female (n=588; 90.3%) with an average age of 15.28 years (SD=2.21), mean percent of median Body Mass Index (mBMI) of 101.91 (SD=31.73), and average duration of illness of 16.74 months (SD=17.63). Cases of DSM-IV Eating Disorder Not Otherwise Specified (EDNOS), now most consistent with DSM-5 Other Specified Feeding or Eating Disorder, decreased from 47.6% to 39.0%, Anorexia Nervosa increased from 29.6% to 33.5%, and Bulimia Nervosa increased from 22.7% to 24.7%.Consistent with previous studies, and in keeping with the aims of the DSM-5 for eating disorders, the revised diagnostic criteria reduced cases of DSM-IV EDNOS and increased cases of specified eating disorders. 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:578-581).

Eating Disorders in Adolescent and Young Adult Males: Presenting Characteristics JOURNAL OF ADOLESCENT HEALTH Vo, M., Lau, J., Rubinstein, M. 2016; 59 (4): 397-400


Data on the clinical characteristics of adolescent males with eating disorders are limited. The purpose of this study was to describe the demographic characteristics, presenting vital signs, laboratory results, and relevant risk factors for eating disorders among males presenting to an outpatient adolescent and young adult medicine practice.Retrospective chart review of male eating disorder patients aged of 11-25years presenting to the University of California, San Francisco Adolescent and Young Adult Eating Disorder Program between June 1, 2011, and November 1, 2014. Charts were reviewed for demographic and clinical characteristics and risk factors for eating disorders.Thirty-three patients were included; mean age was 16years. Patients presented with mean heart rate was 58.7 bpm, and orthostatic heart rate change was 22 bpm, with 51.5% meeting Society for Adolescent Health and Medicine hospital admission criteria. Mean percent of median body mass index was 88%. Of patients with available laboratory data, 33.3% were anemic, 23.8% leukopenic, 19.0% thrombocytopenic, and 10.0% neutropenic. Half had a history of a psychiatric disorder; 41.5% had a history of overweight or obesity, and 12.1% had a family history of an eating disorder. The DSM-IV-TR and DSM-5 diagnostic criteria were retrospectively applied to patients, with an increase in diagnosis of anorexia nervosa from 36.4% to 48.5%. Diagnoses of Eating Disorder Not Otherwise Specified, now Other Specified Feeding or Eating Disorder in DSM-5, decreased from 62.6% to 45.5%.Male patients with eating disorders presented with significant abnormalities; patients were bradycardic and orthostatic; and more than half met Society for Adolescent Health and Medicine admission criteria. Patients with available laboratory data demonstrated significant abnormalities consistent with malnutrition. Given that eating disorders are less likely to be detected in males, it is important to recognize early signs of malnutrition, particularly in those who present within the normal body mass index range for age.
