Free-living Validation of the RFPM in Adolescents
Sponsor: Pennington Biomedical Research Center
Summary
The primary aim of this small study is to test the validity of the Remote Food Photography Method and an updated SmartIntake app in a sample of adolescents. The investigators will test the validity (accuracy) of the method/app at estimating energy intake in free-living conditions over approximately three days compared to doubly labeled water. This is a small study that has low statistical power, but will provide important data nonetheless and inform future research.

Interventions
Tests of the validity of the RFPM and SmartIntake app.
Participants who enroll will be trained in using the RFPM/SmartIntake app and a food record and will complete the Food Intake Assessment Preference Survey. They will also use both methods to estimate intake during a simulated lab-based meal (they will not eat during this simulated meal). They will be dosed with DLW at this visit and will use the RFPM for the subsequent 1-2 days to get accustomed to using the method, with the following three days comprising the data collection period.
