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
ApplicationĀ© 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
environment.


Inclusion Criteria:



- 3-5 years old

- Attends Head Start

- African-American

- Hispanic American

- Can physically complete the tasks required in the proposed research

Exclusion Criteria:

- Younger than 3 years old

- Older than 5 years old

- Does not attend Head Start

- Race/Ethnicity other than African-American or Hispanic-American

- Cannot physically complete the tasks required in the proposed research

Type of Study:

Observational

Study Design:

Time Perspective: Cross-Sectional

Outcome Measure:

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).

Outcome Description:

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.

Outcome Time Frame:

12 months

Safety Issue:

No
