Enhancing the Accuracy of Self-Reported Dietary Intake in Young Children: Development of Two Proxy Reporting Protocols for Self-Reported Dietary Assessment
The University of Tennessee, Knoxville
Summary
The goal of this crossover randomized controlled trial is to develop a proxy reporting protocol for a traditional 24-hour dietary recall (24HR) and an ecological momentary assessment (EMA) assisted 24-HR for use among children between the ages of 2 and 5 years. The main aims are to: 1. Assess the usability and feasibility of each proxy-reporting protocol and dietary assessment methodology. 2. Describe the dietary misreporting captured using each proxy-reporting protocol, and 3. Explore the accuracy of energy intake estimation of the 24HR and EMA+24HR methods, compared to objectively measured food intake. During the research study, participants will: 1. Be provided with one meal and two snacks each day to provide to their child on three consecutive days. Foods can be offered to their child at times of their choosing, and leftovers will be placed back into reusable food storage containers to be picked up by research study staff. Uneaten foods will be weighed for an objective measure of intake. 2. The day after study-provided foods are given to the child, the adult caregiver will complete a proxy-reported 24HR phone call with a trained research assistant. 3. In the EMA+24HR condition, caregivers will be provided access to an online platform where they will upload pre- and post-photographs of all of their child's eating occasions across the three days that study-provided foods are eaten.
Description
This crossover, randomized controlled trial compares two proxy-reported dietary assessment protocols among caregivers with a child between the ages of 2 and 5 years. It also examines the dietary misreporting captured in each protocol and the accuracy of energy intake estimation from each methodology compared to objectively measured food intake. Caregivers with a child between the ages of 2 and 5 years and randomly assigned to one of two starting conditions: 1) traditional 24-hour dietary recall (24HR) or 2) Ecological momentary assessment (EMA)-assisted 24HR (EMA+24HR). Caregivers will complet…

Interventions
- OtherEcological Momentary Assessment
The EMA platform will allow for the primary caregiver (or any other adult with whom the child eats foods with) to upload pre- and post-photographs of all eating occasions. The photographs will be time-stamped and will be used by trained research assistants during the 24HR to aid in collection of accurate information about what the child consumed. The research assistant will be trained on how to prompt the caregiver for inaccuracies in reporting as needed.
- OtherTraditional 24-hour dietary recall
Participants will complete a traditional 24-hour dietary recall via telephone, following the USDA five-step multiple pass method. Participants will receive a standardized food amounts booklet (FAB) to help with quantifying portion sizes consumed.
