An observational study in Comparison of Energy Intake Methods, sponsored by Pennington Biomedical Research Center. Completed at 1 site in United States. Open to participants aged 12 Years to 18 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-11-04.
Sponsored by Pennington Biomedical Research Center · Observational
The Primary Aim of the project is to modify the RFPM for adolescents and to address the concerns identified by the reviewers of the first grant application. We will then test the RFPM's validity (accuracy) compared to the validity of pen-and-paper food records.
The Primary Aim of the project is to modify the RFPM for adolescents and to address the concerns identified by the reviewers of the first grant application. We will then test the RFPM's validity (accuracy) compared to the validity of pen-and-paper food records. Our experience and the literature indicate that the RFPM is acceptable and feasible in school settings. Following modification of the RFPM and pilot testing with 4 adolescents, we will test the reliability and validity of both the RFPM and food records when used by 60 adolescents (12 to 18 years of age). During one week, participants will use the RFPM and during another week they will use food records (the order will be balanced across participants). The accuracy of each method will be examined by comparing energy and nutrient intake (collectively referred to as food intake or FI) to three gold standards: 1) doubly labeled water or DLW (energy intake only, or EIDLW), 2) a laboratory-based test meal (FILaboratory), and 3) food intake during lunch in a school cafeteria (FISchool). User-satisfaction and participant burden will also be compared between methods, and a cost-effectiveness analysis will determine if and under what conditions one method is more cost-effective than the other.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
-weight unstable (>1.1 pounds weight change in one week based on regressed daily body weights).
Doubly Labeled Water (DLW)
Doubly labeled water will be used to measure total daily energy expenditure (TEE) and Energy Intake.
Time frame: 2 weeks
The Remote Food Photography Method (RFPM)
In brief, adolescents will be trained to use a Smartphone and the Food Image App to capture images of their food selection and plate waste and to send the data packets to Food Photo II via the wireless network.
Time frame: 7 days
Pen-and-paper Food Records
Participants will be instructed how to keep a food record and estimate portion size during a session at the Center. Participants will also receive a packet containing the food protocol outline, food record form, guide to portion sizes, guidelines for description of foods, and tips for recording food intake. Participants will be instructed to record everything they eat or drink, recording the food item, portion size, time of consumption, and meal designation.
Time frame: 7 days
