ntroduction
:
The Body Shape Questionnaire is a widely-used self-
report measure of body shape dissatisfaction. We aimed to establish
psychometric properties and report normative data for the Norwegian
14-
item BSQ in a clinical and non-clinical sample which included men.
Methods:
A total of 423 female students, 267 male students, and 56 female
inpatients (AN and subthreshold AN) were administered the BSQ, the Body
Checking Questionnaire (BCQ) and the EDE-Q.
Results:
On average, the
male and female controls were aged 21 years (SD = 5.7) and 24 years
(
SD = 9.9), with mean BMIs of 24.1 (SD = 12.7) and 22.3 (SD = 3.6).
Patients were 19 (3.5) years with a mean BMI of 16.7 (SD = 1.9). Divergent
validity was indicated by significantly different means of 23.0 (8.4) and 35.8
(15.2)
vs 57.2 (18.8), for the M:F controls vs patient group, respectively.
Cronbach’s alpha was satisfactory for all three groups (0.92, 0.96 and
0.95).
The BSQ correlated significantly with the BCQ and EDEQ. Younger
age and higher BMI were associated with higher BSQ scores among
women.
Conclusions:
Our study provides psychometric support for the
Norwegian version of the BSQ-14 among a clinical and non-clinical sample
of both young men and women. The BSQ-14 was investigated due to the
availability of Swedish and German normative data. However, the existence
of multiple abbreviated versions of the BSQ, although psychometrically
supported, may potentially complicate efforts to compare directly across
studies.

Purpose
:
ADHD has been associated with obesity and binge eating
disorder in adults; however there is little data in children. We examined
the association between ADHD and LOC in children.
Methods:
79
non-
treatment seeking children (8 to 14 years) were administered the Child
Eating Disorder Examination and Standard Pediatric Eating Episode
Interview to identify LOC. ADHD diagnosis required both Kiddie-SADS-
Present and Lifetime Version parent and child interviews and Conners-3
(
Parent) DSM-IV Scales of Inattention or Hyperactivity (t score>65).
Results
:
31
of 44 children with ADHD had LOC (70%). Children with ADHD
had 12.7 times higher odds of LOC (p<0.001), even after adjusting for age,
sex, race and BMI z-score. Children with ADHD were significantly more
likely to have higher BMI z-scores (p<0.01) when adjusted for age, sex
and race. LOC was a partial mediator of the relationship between ADHD
and BMI z-score. Stimulant use was not significantly associated with BMI
z-score.
Conclusions:
Children with ADHD had significantly increased
odds of having LOC, even after adjusting for being overweight or obese.
Children with ADHD were more likely to be overweight or obese compared
to children without ADHD. Stimulant use did not affect weight status.
These findings highlight the need to further investigate possible shared
mechanisms between ADHD symptoms such as impulsivity and disinhibited
eating.

Retention in an Urban Community Hospital Weight Management
Treatment-Seeking Sample

Introduction
:
Binge Eating (BE) appears to be equally prevalent across
racial/ethnic groups. Most data concerning BE from clinical trials and
specialty clinics underrepresent ethnic minorities. Data are needed from
urban clinical settings where minorities are more likely to present. The
current study aimed to assess and explain ethnic group differences in
BE prevalence, distress, and treatment retention in an ethnically-diverse
weight management sample. Method: N=430 patients presenting for
weight management at a large community hospital completed a battery of
self-report measures including BE frequency, distress, and stigma. Data
concerning treatment retention was collected at 6-month follow up. Data
were analyzed using robust maximum likelihood estimation (MLR).
Results
:
Recurrent BE prevalence ranged from 20-30% across ethnic
groups. 25% of participants reported significant BE distress and wanting
treatment for BE, but no participants’ records reported BE treatment.
Though African Americans had higher BMI and similar BE distress, they
had lower obesity treatment retention rates than Caucasian and Hispanic
participants. Obesity stigma was a significant predictor of retention, and
mediated the relationship between African American ethnicity and retention.
Conclusions
:
BE is prevalent among overweight ethnic minorities at a
common point of entry for health services utilization. Cultural factors and
retention among African Americans are important targets for treatment.

Selective Prevention Programs That Target Both Eating Disorders and
Obesity
Paul Rohde, Eric Stice
Oregon Research Institute, Eugene, OR, USA
Introduction
:
Interventions that address both eating disorders and
obesity are needed because both are associated with marked impairment,
morbidity, and mortality. This presentation will describe 3 randomized trials
evaluating prevention programs targeting both eating disordered behaviors
and unhealthy weight gain.
Methods
:
Female college students at high-risk
for these outcomes due to body image concerns (N=398) were randomized
to the
Healthy Weight
group prevention program, which promotes
gradual lasting improvements to dietary intake and physical activity, or an
educational brochure control.
Results
:
Healthy Weight
participants showed
significantly less increases in eating disorder symptoms and unhealthy
weight gain, and a 60% reduction in eating disorder onset over 2-year
follow-up. Moderator analyses found stronger eating disorder symptom
effects for youth with initially elevated symptoms and stronger BMI effects
for youth with initially elevated symptoms and BMI. The authors will also
present preliminary data from trials of an Internet dissonance eating
disorder prevention program (N=107) and a dissonance-based obesity
prevention program (N=120) that appear to be producing effects for both
eating disorder symptoms and unhealthy weight gain.
Conclusions
:
Given
that both eating disorders and obesity are very prevalent, yet resistant to
treatment, it will be vital to develop and disseminate prevention programs
that effectively reduce these major public health problems.

Assessment of Fat Taste Sensitivity in People With and Without
Anorexia Nervosa
Janet E. Schebendach, Michael Devlin, B. Timothy Walsh
Columbia University, NY, NY, USA,
Introduction
:
Avoidance of dietary fat is a characteristic eating behavior of
individuals with Anorexia Nervosa (AN). To date, no study has determined
whether AN patients are better able to taste fat in foods than individuals
without an eating disorder.
Methods
:
AN (n=25) and healthy control (HC;
n=25) participants were presented with a series of nine of cream cheese
samples of three differing fat contents (0, 6, and 9 g fat per wt. oz.) and
asked to taste and rate each sample from very low fat to very high fat.
Results
:
Repeated measures ANOVA found no significant (ns) main
effect or interaction effect between fat content and diagnosis; however, a
significant three-way interaction between fat content, diagnosis, and trial
was observed. Post-hoc analysis revealed ns findings within the NC group,
but a significant fat content by trial interaction within the AN group. Upon
further exploration, a significant trial effect was found in AN patients for
the fat free samples only.
Conclusions
:
There is a tendency for individuals
to recognize a taste difference among cream cheese types, but there is
no evidence that patients are better able to judge fat content compared
to controls. Post-hoc analysis suggests that AN patients may improve in
their ability to identify a fat free food with training (i.e., over multiple trials);
however, the significance of this finding is unclear, and its interpretation
limited by the exploratory nature of this study.

Introduction:
The internalization of weight bias predicts clinically significant
eating pathology among overweight adults. However, these outcomes have
not yet been assessed in lean individuals, who may perceive themselves
to be overweight and subsequently internalize some degree of weight bias.
Methods:
Participants were 198 lean (mean BMI: 22.29 ± 1.89) adults who
completed the Weight Bias Internalization Scale (WBIS) and measures of
disordered eating behaviors and attitudes via an online survey.
Results:
Based on convergence of responses from the EDE-Q and
QEWP-R (n = 145), and using DSM-5 behavioral criteria, 7.6% and 11.1%
of participants were classified into a binge/purge and binge eating group,
respectively. WBIS scores were significantly higher among those with
binge and/or purge behaviors compared to those without eating pathology.
Bivariate correlations revealed positive associations between WBIS
score and BMI, depression, and all EDE-Q subscales (Restraint, Eating
Concern, Shape Concern, Weight Concern). Logistic regressions indicated
that internalized weight bias was significantly predictive of binge/purge
behaviors (OR = 4.67, 95% CI: 2.38- 9.17,
p
<.001) and binge eating (OR
