Dietary Intake and Eating Behaviors in Adolescents Who Undergo Bariatric Surgery

The dietary and eating behavior outcomes for adolescents who undergo bariatric surgery are
virtually unknown. The main trial of the Teen-LABS consortium is not studying dietary intake
and eating behavior before and after bariatric surgery. The consortium, however, provides a
unique opportunity to investigate these issues in a large and diverse sample through the
context of the proposed ancillary study.

Inclusion Criteria:

- 19 years old or younger

- have a BMI > 30 kg/m2

- have attained or nearly attained physical maturity and have a history of
unsuccessful, organized attempts at weight management.

- must demonstrate reasonable decision making abilities

- must also fit the following criteria: (1) no prior bariatric surgical procedure, (2)
no physical illness not due to obesity, and (3) no full-time special education (due
to the high reading demand of study participation).

- Participants will be from all racial and ethnic groups and be both male and female.

Exclusion Criteria:

- We will not exclude participants from this trial based on health status or medication
usage. Instead, we will track medical conditions and medication usage at every
assessment point throughout the investigation to assess the possible influence of
these variables on changes in weight, dietary intake, and eating behavior.
