Early Childhood Dietary Assessment Study

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 complete the first assessment condition, and then, following a two-week washout period, will complete the other condition. In both conditions, caregivers will receive one meal and two snacks to provide to their child on three consecutive days. In addition to providing food, caregivers will identify a second caregiver (i.e., another parent, adult sibling, outside family member, or childcare worker) who will provide at least two eating occasions with study-provided foods over the three days. Including a caregiver outside of the primary proxy reporter will help assess the ability to accurately capture foods consumed away from the primary reporter, which has been identified as a challenge in dietary assessment among young children. The day after the child consumes study-provided foods, the caregiver will complete a 24HR via telephone with a trained research assistant following the United States Department of Agriculture five-step multiple pass method. After completing each dietary assessment condition, caregivers will complete an electronic survey that assesses the usability and acceptability of each proxy reporting protocol and dietary assessment condition. The primary aims of this study are to: 1. Assess the feasibility, which will include the usability and acceptability, of the proxy reporting protocol for the 24HR and EMA+24HR. 2. Describe the dietary misreporting captured in the 24HR and EMA+24HR assessment strategies. A secondary aim of the study will be to explore the accuracy, via determining agreement, of the 24 and EMA+24HR methods compared to objectively measured food intake, specifically in regard to energy intake.
