BACKGROUND Although the purpose of federal dietary guidance is to improve eating habits, few studies have described awareness of guidance and concurrent diet quality. OBJECTIVE The objective of the current study was to examine the prevalence of individuals who reported hearing of dietary guidance icons and to describe the association between having heard of the icons and diet quality. DESIGN This study was a cross-sectional survey. PARTICIPANTS/SETTING Participants (n=23,343) were from the National Health and Nutrition Examination-What We Eat in America survey 2005-2014 cycles. MAIN OUTCOME MEASURES Awareness of the Food Guide Pyramid, MyPyramid, or MyPlate icons by sociodemographic characteristics and diet quality were measured using Healthy Eating Index (HEI) scores derived from 24-hour recall data. STATISTICAL ANALYSES PERFORMED Global Wald tests were used to test for differences in awareness of the icons within sociodemographic groups. Total HEI scores were calculated using the population-ratio method. Z-scores were used to test differences in HEI total scores between those with knowledge of the icons and those who responded negatively. RESULTS In all cycles, those with less than a high school diploma were the least likely to report having heard of the icons (P<0.001). In every wave except 2011 to 2012, participants with low or marginal food security status were less likely to report affirmatively (P<0.001), and Supplemental Nutrition Assistance Program (SNAP) participants and SNAP-eligible nonparticipants were least likely to report having heard of the icons (P<0.001) except for 2005 to 2006. HEI scores were higher among those who had heard of MyPyramid in 2007-2012 (P<0.05) and MyPlate in 2013-2014 (P<0.001) compared with those who had not heard of the icon. CONCLUSIONS Recognition of federal dietary guidance icons was associated with higher diet quality recently, but the cross-sectional nature of the data precludes conclusions of causality. Further research is needed to identify barriers and promoters for translating awareness of the federal dietary guidance icons into healthful food purchasing and food consumption decisions.

对联邦饮食指南图标的认可与更高的饮食质量有关

背景虽然联邦饮食指导的目的是改善饮食习惯,但很少有研究描述了指导意识和同时进行的饮食质量。目标 本研究的目的是检查报告听说过饮食指导图标的个人的流行率,并描述听说过这些图标与饮食质量之间的关联。设计 本研究是一项横断面调查。参与者/环境 参与者 (n=23,343) 来自全国健康和营养检查 - 我们在美国吃什么调查 2005-2014 周期。主要结果测量 使用源自 24 小时回忆数据的健康饮食指数 (HEI) 分数测量社会人口学特征和饮食质量对食品指南金字塔、MyPyramid 或 MyPlate 图标的认识。执行的统计分析 Global Wald 测试用于测试社会人口学群体中对图标的认识差异。使用人口比率方法计算总 HEI 分数。Z-scores 被用来测试那些知道图标的人和那些消极回应的人之间 HEI 总分的差异。结果 在所有周期中,高中文凭以下的人报告听说过这些图标的可能性最低(P<0.001)。在除 2011 年至 2012 年之外的每一波中,粮食安全状况低下或边缘的参与者不太可能做出肯定报告(P<0.001),补充营养援助计划 (SNAP) 参与者和符合 SNAP 条件的非参与者报告听说过的可能性最小除 2005 年至 2006 年之外的图标 (P<0.001)。与没有听说过该图标的人相比,2007-2012 年听说过 MyPyramid(P<0.05)和 2013-2014 年 MyPlate(P<0.001)的人的 HEI 得分更高。结论 对联邦饮食指南图标的认可与最近更高的饮食质量有关,但数据的横截面性质排除了因果关系的结论。需要进一步的研究来确定将联邦饮食指南图标的意识转化为健康食品购买和食品消费决策的障碍和促进因素。但数据的横截面性质排除了因果关系的结论。需要进一步的研究来确定将联邦饮食指南图标的意识转化为健康食品购买和食品消费决策的障碍和促进因素。但数据的横截面性质排除了因果关系的结论。需要进一步的研究来确定将联邦饮食指南图标的意识转化为健康食品购买和食品消费决策的障碍和促进因素。
