Remote Food Photography for the Real-time Measurement of Children's Food Intake
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.

Detaljeret beskrivelse
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.

The Remote Food Photography Method (RFPM)
Tidsramme: 7 days

Pen-and-paper Food Records
Tidsramme: 7 days

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.
