背景资料：2015年健康饮食指数（HEI-2015）评分尚未在同行评议的文献中发表，用于美国儿童的全国代表性样本。目的：本研究的目的是使用HEI-2015来描述美国儿童整体和各种社会人口学人群的饮食质量。设计：我们使用了3个周期的NHANES饮食数据集（2009 - 2010，2011-2012和2013-2014），通过使用人口比例法计算2-18岁儿童（n = 9000）的HEI-2015总分和组分得分。饮食质量评分计算总体和年龄（2-5岁，6-11岁和12-18岁），性别，种族或民族（非西班牙裔黑人，非西班牙裔白色，墨西哥裔美国人，其他西班牙裔和其他种族），和家庭贫困收入比（低于或等于或高于贫困阈值）。计算HEI-2015平均总分和组分评分沿着95%CIs.Results：儿童的HEI-2015总平均评分为54.9（范围：0-100）。随着年龄组的增加，总评分降低;最年轻年龄组儿童的总平均评分显著高于2个较大年龄组（分别为60.1、53.9和52.0）。非西班牙裔黑人儿童的总平均分显著低于墨西哥裔美国儿童、其他西班牙裔儿童和其他种族儿童（分别为52.6、57.0、56.8和57.1）。非西班牙裔白色儿童的总平均分显著低于墨西哥裔美国儿童（54.2比57.0）。男孩和女孩之间或贫困线班级之间的总平均分没有明显差异。交叉分类的社会人口学特征的总平均分数一般遵循相同的模式观察到的单一特征，发生在年龄和种族或族裔class.Conclusions显着差异：美国儿童的饮食质量仍然较低的整体，在一些社会人口，特别是年龄和种族或族裔的持续差异。这些分析的结果可以帮助指导儿童营养研究人员，从业人员和其他利益相关者的努力。
Background: To date, Healthy Eating Index 2015 (HEI-2015) scores have not been published in the peer-reviewed literature for nationally representative samples of American children.Objective: The aim of this study was to use the HEI-2015 to describe the diet quality of American children overall and within various sociodemographic populations.Design: We used 3 cycles of NHANES dietary data sets (20092010, 2011-2012, and 2013-2014) to calculate HEI-2015 total and component scores by use of the population ratio method for children aged 2-18 y (n = 9000). Diet-quality scores were computed overall and by age (2-5, 6-11, and 12-18 y), gender, race or ethnicity (non-Hispanic black, non-Hispanic white, Mexican American, other Hispanic, and other race), and family poverty-to-income ratio (below or at or above the poverty threshold). HEI-2015 mean total and component scores were computed along with 95% CIs.Results: The HEI-2015 total mean score for children overall was 54.9 (range: 0-100). As the age group increased, the total scores decreased; the total mean score was significantly higher for children in the youngest age group compared with the 2 older age groups (60.1 compared with 53.9 compared with 52.0, respectively). The total mean score was significantly lower for non-Hispanic black children compared with Mexican American children, other Hispanic children, and children of other races (52.6 compared with 57.0, 56.8, and 57.1, respectively). The total mean score was significantly lower for non-Hispanic white children compared with Mexican-American children (54.2 compared with 57.0). No differences in total mean scores were apparent between boys and girls or between poverty threshold classes. The total mean scores for cross-classified sociodemographic characteristics generally followed the same patterns observed for single characteristics, with notable differences occurring within age and race or ethnicity classes.Conclusions: The diet quality of American children remains low overall, with continued disparities across some sociodemographic populations, notably age and race or ethnicity. The results of these analyses can help guide the efforts of child nutrition researchers, practitioners, and other stakeholders.
