Environmental Strategies & Behavior Change to Reduce Overeating in Obese Children

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified January 2014 by Thomas Robinson, Stanford University.
Recruitment status was:  Active, not recruiting
Sponsor:
Collaborator:
National Heart, Lung, and Blood Institute (NHLBI)
Information provided by (Responsible Party):
Thomas Robinson, Stanford University
ClinicalTrials.gov Identifier:
NCT01221220
First received: October 13, 2010
Last updated: January 23, 2014
Last verified: January 2014
  Purpose
There is a need for effective weight control methods for obese children. Environmental strategies such as reducing the size of dishware and serving utensils, storing food out of view and reducing food consumption while watching television may reduce food intake without requiring conscious, cognitive self-control. The investigators propose to test these methods when added to a current state-of-the-art behavioral program.

  Eligibility

Ages Eligible for Study:   8 Years to 15 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:Inclusion criteria: 8-15 year old obese children (BMI ≥ 95th percentile on the 2000 CDC BMI reference) on the date of randomization. Our standard Stanford Pediatric Weight Control Program eligibility criteria will apply: both child and parent/guardian must want to join, both child and at least one parent/guardian must agree to attend sessions, and must agree to not miss more than 2 consecutive sessions. As we interested in testing generalizable strategies for weight control in diverse populations, the eligibility criteria are designed to be liberal, to maximize the generalizability of the results, but also maintain the internal validity of the test of the intervention.

Exclusion Criteria:Exclusions: To enhance internal validity, children will not be eligible if they:

  1. have been diagnosed with a medical condition affecting growth (a genetic or metabolic disease/syndrome associated obesity, Type 1 diabetes, Type 2 diabetes taking medication, chronic gastrointestinal diseases, Chronic renal diseases, uncorrected structural heart disease, heart failure, heart transplant, anorexia nervosa or bulimia nervosa or binge eating disorder [present or past], AIDS or HIV infection, pregnancy);
  2. are taking medications affecting growth (systemic corticosteroids more than 2 weeks in the past year, insulin, oral hypoglycemics, thyroid hormone, growth hormone);
  3. have a condition limiting their participation in the interventions (e.g., unable to participate in routine physical education classes at school, requiring oxygen supplementation for exertion, developmental or physical disability preventing participation in interventions, children or parents/guardians who cannot medically participate in mild dietary restrictions and/or increased physical activity for any reason);
  4. have a condition limiting participation in the assessments (child or primary caregiver not able to read surveys in English or Spanish, child two or more grade levels delayed in school for reading and writing in his/her native language);
  5. are unable to read, understand or complete informed consent in English or Spanish;
  6. plan to move from the San Francisco Bay Area within the next 18 months.
