Study type | Interventional |
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.

Primary | Equivalence between energy intake (kcal/day) measured with the RFPM and DLW | Energy intake is measured by the RFPM and DLW in kcal per day over 3 days. We will use the mean of the 3 days in the analyses. Two one-sided paired t-tests (a = 0.05 for each) will be performed in this pilot with equivalence bounds at 2% increments between 8% and 34% to determine equivalence in kcal estimates between RFPM and DLW. | 3 days | |
Secondary | Mean difference between the RFPM and DLW on kcal/day | RFPM - DLW (kcal), with each method measuring energy intake over three days, and the mean of the three days for each method being included in the calculations and analyses. | 3 days | |
Secondary | Mean percentage error of RFPM relative to DLW | MPE = (RFPM - DLW) / DLW × 100 | 3 days |
