Bulimia in children and adolescents

Eating disorder onset during childhood is associated with higher trauma dose, provisional PTSD, and severity of illness in residential treatment

OBJECTIVE

Age of eating disorder (ED) onset has been of significant interest to both researchers and clinicians. The identification of factors associated with early or child onset has important prevention and treatment implications. The presence of prior trauma, resultant posttraumatic stress disorder (PTSD), ED severity, and comorbid psychopathology are of particular relevance to age of ED onset, but data are limited.

METHODS

Adults (≥18 years, 93% female, total n = 1283) admitted to residential ED treatment self-reported age of ED onset. Patients were divided into child onset (ages 5-10 years), adolescent onset (11-17 years), and adult onset (≥18 years) groups and compared on a number of clinical features and assessment measures.

RESULTS

The child onset group had significantly higher rates and doses of traumatic life events; higher current PTSD prevalence; higher BMIs, higher severity of ED, depression and state-trait anxiety symptoms; worse quality of life; and more prior inpatient and residential admissions for ED treatment, in comparison to both the adolescent and adult onset groups. Similarly, the adolescent onset group had significantly higher rates than the adult onset group.

CONCLUSIONS

These results have important implications for prevention, treatment and long-term follow-up and highlight the need for early trauma-focussed treatment of ED patients.

Provisional posttraumatic stress disorder is associated with greater severity of eating disorder and comorbid symptoms in adolescents treated in residential care

OBJECTIVE

Past traumatic events, subsequent posttraumatic stress disorder (PTSD) and related psychiatric comorbidities are commonly associated with eating disorders (EDs) in adults but remain understudied in adolescents.

METHODS

Adolescent participants (mean [SD] age = 15.1 ± 1.5 years, 96.5% female) with EDs entering residential treatment (n = 647) at six sites in the United States completed validated self-report assessments of ED, PTSD, major depression, anxiety disorders and quality of life. Provisional DSM-5 PTSD diagnoses (PTSD+) were made via the Childhood Trauma Questionnaire, admission interviews and the PTSD Symptom Checklist for DSM-5.

RESULTS

PTSD+ occurred in 35.4% of participants, and those with ED-PTSD+ had significantly higher scores on all assessments (p ≤ 0.001), including measures of ED psychopathology, major depression, anxiety disorders and quality of life, as well as significantly higher rates of all forms of childhood trauma. Those with PTSD+ also exhibited a significantly higher percent median body mass index for age and sex and a lower propensity toward anorexia nervosa, restricting type.

CONCLUSIONS

Results confirm that adolescent patients in residential treatment with ED-PTSD+ are more symptomatic and have worse quality of life than their ED counterparts without PTSD. Integrated treatment approaches that effectively address ED-PTSD+ are greatly needed in ED programs that treat adolescents.

Eating disorders, trauma, and comorbidity: focus on PTSD

This paper reviews the relationships among eating disorders (EDs), trauma, and comorbid psychiatric disorders, with a particular focus on posttraumatic stress disorder (PTSD). There have been a number of significant conclusions in the literature, applicable to clinical practice, which are essential to the understanding of the relationships between EDs and trauma. These are summarized as follows: a) childhood sexual abuse (CSA) is a nonspecific risk factor for EDs; b) the spectrum of trauma linked to EDs has been extended from CSA to include a variety of other forms of abuse and neglect; c) trauma is more common in bulimic EDs compared to nonbulimic EDs; d) findings linking EDs with trauma have been extended to children and adolescents with EDs; e) findings linking EDs with trauma have been extended to boys and men with EDs; f) multiple episodes or forms of trauma are associated with EDs; g) trauma is not necessarily associated with greater ED severity; h) trauma is associated with greater comorbidity (including and often mediated by PTSD) in ED subjects; i) partial or subthreshold PTSD may also be a risk factor for BN and bulimic symptoms; and j) the trauma and PTSD or its symptoms must be expressly and satisfactorily addressed in order to facilitate full recovery from the ED and all associated comorbidity.

Diagnostic criteria for anorexia nervosa: looking ahead to DSM-V

In considering possible revisions to the diagnostic criteria for anorexia nervosa (AN), questions can be raised regarding the 85% cutoff and consideration could be given to using a body mass index (BMI) score instead. The criterion most likely to change in the 4th ed. of the Diagnostic and Statistical Manual of Mental Disorders (Washington, DC: American Psychiatric Association) is the amenorrhea criterion because this does not appear to add to the diagnostic specificity.
