Interpretation and Understanding of the Dietary Guidelines for Americans Consumer Messages Among Low-Income Adults

摘要

Objective: The objective of this study was to determine the interpretation, understanding, and implementation of the Dietary Guidelines for Americans (DGA) consumer messages among low-income adults and compare findings to perceptions of the messages for consumers by community nutrition educators. Methods: In this mixed methods, cross-sectional study, a convenience sample of low-income adults (n = 98) with a child between the ages of 3 and 10 years old and nutrition educators (n = 9) were interviewed individually about the DGA messages, food-related behaviors, and barriers related to consuming fruits, vegetables, and whole grains. Interviews were audio-taped, transcribed verbatim, and analyzed using the inductive approach. Interpretation and ranking of the clarity and ease of the DGA messages by low-income adults and nutrition educators and perceptions about the messages were assessed. Descriptive statistics were conducted for demographic data and Fisher's exact tests were used to examine differences regarding the clarity and ease of the messages among low-income adults and nutrition educators. Results: According to the interview results, messages that tended to be misinterpreted most frequently were on topics such as sodium, fruit and vegetables, portions, and whole grain intake. Low-income adults and nutrition educators also differed in perceptions for the message clarity addressing whole grain servings (p = .001), avoiding oversized portions (p = .002), and comparing sodium (p < .001). Conclusions: Improvements in the DGA consumer messages are warranted to improve clarity and feasibility for low-income adults through new communication tools or strategies that complement the DGA.
