Comparison of Energy Intake MethodsFPPNCT01719445
The Food Phone Project
An observational study of Comparison of Energy Intake Methods, run by Pennington Biomedical Research Center at 1 site in United States.
Trial summary
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. Read more about this study

About this study
Official title: 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.
Read the 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Doubly Labeled Water (DLW)
Doubly labeled water will be used to measure total daily energy expenditure (TEE) and Energy Intake.
Measured: 2 weeks
Secondary outcomes (1)
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.
Measured: 7 days

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Doubly Labeled Water (DLW) (time frame: 2 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01719445, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
