The primary aim of the proposed pilot study is to assess the effects of fast food meals, varying in serving size and rate of delivery, on energy (calorie) intake in adolescents.
Behavioral: Condition A (see detailed summary)
Behavioral: Condition B (see detailed summary)
Behavioral: Condition C (see detailed summary)
|Study Design:||Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single Blind
Primary Purpose: Prevention
|Official Title:||Fast Food Feeding in Youth|
- Energy (calorie) intake during fast food feedings, assessed by direct observation
- Energy (calorie) intake during the day of the visit and the day after the visit, assessed by multiple-pass dietary recall interview methodology
|Study Start Date:||July 2005|
|Estimated Study Completion Date:||September 2005|
Using a three-period crossover design, the investigators will evaluate three acute feeding conditions.
- Under Condition A, the total amount of food in a large fast food meal will be delivered on a single tray at Time 0 (start of meal).
- Under Condition B, the same fast food meal will be equally divided among 4 separate portions, with all portions delivered at Time 0.
- Under Condition C, the meal again will be equally divided among 4 separate portions, but the portions will be delivered at 15-minute time intervals (Time 0, 15 minutes, 30 minutes, 45 minutes).
