Describing Ecological Momentary Assessment Methods for Collecting Dietary Intake in a Racially/Ethnically Diverse Sample

Abstract

ObjectivesEcological momentary assessment (EMA) is an innovative tool being used in the obesity field to capture real-time information about people’s health. A recent systematic review regarding the use of EMA to assess dietary intake and physical activity in youth found the need for standardized reporting of EMA measures and methods. This presentation will discuss EMA methods used in the NIH-funded Family Matters study, including survey design, registration/technology, EMA protocols, implementation, and lessons learned for future EMA studies. MethodsFamily Matters is an incremental, two-phased (Phase I = 150 participants; Phase II = 627 participants), mixed-methods study conducted with a racially/ethnically diverse and immigrant/refugee sample from largely low-income households. Across two phases, the Family Matters research team designed and administered EMA surveys to parents of 5–9 year olds to measure momentary factors of importance to child weight and weight-related behaviors including parent feeding practices, child eating behaviors, meal preparation, and foods served at family meals. ResultsEMA data allowed for many cutting-edge research questions to be addressed, innovative analyses to be run, and methodological approaches to be advanced. Many diet-related topics were investigated, including 1) the investigation of both within-and across-day relationships between transient and chronic stress and parent feeding practices; 2) parental stress and mood earlier in the day and its association with parent feeding practices later in the day; and 3) family meal characteristics by meal type and day of the week. Additionally, concordance between diet-related EMA measures and objectively collected 24-hour dietary recalls was examined. Family Matters EMA diet-related measures will be presented and related results discussed. ConclusionsThis presentation will be valuable for researchers interested in using EMA for collecting obesity-related measures, such as dietary intake, physical activity, parent feeding practices, and stress/mood.
