Validation of a Digital Diet Method for Use With Preschoolers
The goal of the proposed research is to modify the Remote Food Photography Method (RFPM) for
use with preschoolers. Primary caregivers (the majority will be mothers) and HS assistants
will use a Smartphone to capture 24-hour images of HS children's food selection and plate
waste. The RFPM, Ecological Momentary Assessment (EMA). and the Food Photography
Application© will be used to estimate the energy and nutrient intake of preschoolers. The
accuracy of the RFPM will be examined by determining the energy and nutrient intake
(collectively referred to as food intake [FI]) to established methods: 1) actual gram (g)
weights of laboratory-based test meals and 2) doubly labeled water (DLW) in a natural
Time Perspective: Cross-Sectional
This experiment will compare energy intake (EI) calculated using the test method (Remote Food Photography Method or RFPM) against energy intake calculated using weight measures (actual weighing of all food/beverages consumed).
The Bland-Altman method was used to measure the agreement between digital photography estimated weight and actual weight. This method uses a two step process that evaluates the accuracy (validity) of a "new" measurement technique compared to and existing "gold standard", which was the actual weights of foods.
