  Purpose

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.

Primary Outcome Measures:
  • Doubly Labeled Water (DLW) [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
    Doubly labeled water will be used to measure total daily energy expenditure (TEE) and Energy Intake.


Secondary Outcome Measures:
  • The Remote Food Photography Method (RFPM) [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    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.


Other Outcome Measures:
  • Pen-and-paper Food Records [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    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.


Biospecimen Retention:   Samples Without DNA

Urine collection as part DLW procedure.

RFPM/Paper and Pen Method

Detailed Description:

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.
