Objective:
To examine the long-term effects of bariatric surgery (BS) on
psychological functioning and quality of life.
Method:
Obese individuals
undergoing BS, obese individuals participating in a conventional weight
loss treatment (CONV), and obese controls were investigated in a
prospective longitudinal study. BMI, health related quality of life (SF-36),
anxiety and depression (HADS), and self-esteem (Rosenberg Self-
Esteem Scale, RSES) were assessed before treatment, and after 1,
2, 4,
and 9 years after treatment. A total of 78 of 145 bariatric surgery
patients, 130 of 240 conventionally treated patients, and 80 of 121
obese controls completed the 9-year follow-up.
Results:
Weight loss
was significantly greater for the BS compared to the other groups at
all assessment points (all p’s <.001). The CONV group showed more
weight loss than controls at the 1-year and 2-year assessments (p’s
<.001), but did not differ significantly from the control group at the 4-year
(
p = .354) and 9-year (p = .194) assessments. The BS group reported
significantly greater improvements in SF-36 physical component scores
at all post-baseline assessments compared to the other groups. On the
SF-36 mental component, the BS group experienced significantly less
improvements than controls at the 2-year assessment and significantly
less improvements than both the CONV and control group at the 9-year
assessment. No differences were found between the BS group and the
CONV group on changes in depression at any assessment point. While
the BS group showed significantly greater improvements than the control
group in HADS depression scores at 1-year, improvements in depression
were significantly higher in the control group compared to the BS group
at the 9-year assessment. Furthermore, HADS depression scores for
the BS group at the 9-year assessment were significantly increased
from the 4-year assessment (p = .013) and did not differ significantly
from baseline levels (p = .100). No significant differences were observed
between the BS and CONV groups in changes in HADS anxiety scores at
any assessment point. In the BS group HADS anxiety scores increased
significantly from the 4-year to the 9-year assessment (p = .017). Of
note, 9-year anxiety scores did not differ significantly (p = .576) but were
even somewhat higher than pre-surgical scores. While changes in RSES
scores did not differ significantly between study groups at the 1-, 2-,
and 4-year assessments, the change in the BS group was significantly
lower than that compared to the CONV group at the 9-year follow-up.
Conclusion:
The findings indicate that BS results in long-term weight
loss and improvement of physical aspects of quality of life. However,
after initial significant improvement psychological functioning and mental
aspects of quality of life deteriorated significantly in the BS group from
the 4-year to 9-year assessment and were comparable to pre-surgical
levels. Clinical implications of the results and further research questions
will be discussed.

Introduction
:
Research suggests that disordered eating among female
athletes is prevalent and increases risk for the Female Athlete Triad,
subsequent injury, clinical eating disorders (EDs), and other serious long-
term health consequences, e.g., osteoporosis and reproductive disorders.
Despite this, efforts aimed at prevention of EDs among this group remain
limited. A pilot study suggests that an athlete modified version of a
Healthy Weight intervention (HW) can be successfully implemented by
peer-leaders within the constraints of a competitive athletics program with
positive effects at 12 month follow-up.
Methods
:
The present study is a
3-
site randomized controlled trial (1 RO1 MH094448-01) that tests the
efficacy of the HW intervention among female athletes (target N = 500).
Female collegiate athletes from the three sites were randomized to either
the HW prevention program or a brochure waitlist control condition using
group (cluster) randomization based on teams. Teams participating in the
trial included gymnastics, swimming, diving, tennis, track, golf, soccer,
softball, volleyball, basketball, field hockey, lacrosse, and cheerleading.
Participants complete surveys and telephone interviews at baseline, post-
intervention, and at 6, 12, and 18- month follow-up time points.
Results
:
This presentation will outline preliminary results from the first 1.5 years of
this trial. To date, this study has recruited 334 participants (Active=107,
Control=227).
Conclusions
:
Forthcoming.

Previous studies indicate that both stress and cue exposure influence
consumption of palatable foods. The relative reinforcing value (RRV) of
a product is a behavioral economics index which describes the value of
one good relative to another, e.g., food relative to money. RRV is used
to measure economic aspects of craving. We examined the effects of
stress, environmental cues, and interaction of the two on subjective
craving for and RRV of palatable food. Ninety community recruited
participants (60% female) were randomly assigned to one of four
conditions: 1) stress+food, 2) stress+neutral cues, 3) neutral mood+food,
4)
neutral mood+neutral cues. Following the mood induction, participants
were exposed to a buffet of palatable snacks or office supplies. Mood,
craving, and RRV were reported at baseline, following mood induction,
and following cue exposure. There was an increase in stress (
F
=31.44,
p
<0.05) following the negative mood induction. There was a significant
main effect of food cue exposure on craving (
F
=20.06,
p
<0.05), but not a
significant main effect of stress on craving. Our hypotheses that exposure
to both stress and food cues would produce the highest subjective
craving and RRV were not supported (e.g.
F
=2.06,
p
=0.13). However,
there was a trend for female participants to report higher craving following
stress than male participants. Overall, results suggest that the presence
of food cues strongly influenced craving, regardless of level of stress.

Introduction
.
Many patients with bulimia nervosa (BN) also meet criteria
for a lifetime alcohol use disorder (AUD). In order to understand possible
mechanisms contributing to the co-occurrence and perpetuation of these
disorders, this study investigated the importance of impulsivity among
patients with BN with and without an AUD.
Methods
.
Participants with
BN (n=10), BN and a current/past AUD (n=9), and healthy controls (HC;
n=10) completed two multi-item test meals (normal meal/binge meal),
and self-report/behavioral measures (e.g., Barratt Impulsiveness Scale
[
BIS-11], GoStop Impulsivity Paradigm [GSIP]).
Results
.
In comparison
to HC, patients with BN had significantly higher BIS-11 scores and
consumed significantly more energy in the binge meal. Significant
differences between BN patients with and without an AUD were found
only for self-reported alcohol consumption (e.g., average drinks per day)
and the GSIP Ratio. For all patients with BN, total BIS-11 scores were
significantly related to total kcal consumed during the binge meal, total
number of objective bulimic episodes and vomiting reported by patients
in the month before participation, and other measures of eating disorder
symptoms.
Conclusions
.
These preliminary findings suggest impulsivity
may be important for understanding the maintenance of bulimic
behaviors, but additional data are needed to determine whether a shared
diathesis of deficits in impulse control contributes to the development of
BN and AUDs.

Research suggests links among pediatric loss of control (LOC) eating
and other disinhibited eating behaviors such as emotional eating (EE)
and eating in the absence of hunger (EAH). The underlying mechanisms
explaining the overlap among these behaviors remain unclear. We
hypothesized that impulsivity may be an endophenotype accounting
for the co-occurrence of LOC and EE/EAH. Non-treatment-seeking
adolescents (N=93, 74% girls; BMIz=1.0±0.9; 58% non-Hispanic White)
completed the EDE interview to determine LOC presence. Impulsivity
was assessed with a computerized choice impulsivity task as the
proportion of immediate vs. delayed choices. Youth self-reported EE,
and parents reported their children’s EAH via questionnaire. Only among
youth reporting LOC eating (n=25), impulsivity was positively correlated
with EE (
r
=.48,
p
=.04) and with EAH (
r
=.51,
p
=.03), controlling for age,
sex, race, BMIz, and depressive symptoms. These associations were not
present among youth without LOC eating (n=68;
r
s=-.03-.09,
p
s>.47).
Higher impulsivity may partially account for the association between LOC
eating and EE/EAH in adolescents. Adolescents with LOC who are more
impulsive may be prone to eating in response to negative emotions and
