虽然联邦膳食指导的目的是改善饮食习惯，但很少有研究描述指导意识和同步饮食质量。本研究的目的是调查听说过膳食指南图标的个体的流行程度，并描述听说过这些图标与饮食质量之间的关系。设计本研究为横断面调查。参与者（n=23,343）来自2005-2014周期的国家健康和营养检查-我们在美国吃什么调查。主要结果测量：通过社会人口学特征和饮食质量来衡量食物指南金字塔、我的金字塔或我的餐盘图标的认认度，使用从24小时召回数据中得出的健康饮食指数（HEI）得分。统计分析进行了全球沃尔德测试，用于测试在社会人口统计群体中对图标的认识差异。HEI总分采用人口比率法计算。z分数被用来测试那些知道图标的人和那些不知道图标的人在HEI总分上的差异。结果在所有的周期中，那些高中文凭以下的人最不可能听说过这些图标
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
