The purpose of this cross-sectional study was to examine the relationship between meeting the intake recommendations for added sugar (AS) and dietary fiber and overall diet quality in American preschoolers from different ethnic backgrounds.
Data from a nationally representative sample of preschoolers participating in the Continuing Survey of Food Intake by Individuals (CSFII) 1994-1996, and 1998 (n=5,437) were categorized into 3 groups: (1) meeting the recommendation for AS intake (< or = 10% of energy) and dietary fiber (14 g and 20 g in 2- to 3-year-olds and 4- to 5-year-olds, respectively; n=236); (2) meeting only 1 recommendation (n=1,502); and (3) meeting neither (n=3,699). Dietary AS and dietary fiber sources were ascertained. Mean energy intake, nutrient intake, and food group density were established within each category, and student's t test was employed to determine significant differences. Nutrient and food group density was also examined stratified by 4 distinct ethnic groups.
Children meeting both recommendations had better diet quality but also higher energy intakes than children meeting only 1 or neither recommendation.
Most American preschoolers do not meet the dietary intake recommendations for AS and dietary fiber. Health professionals should work together to increase dietary fiber density and reduction of added sugar in the diets of preschoolers to improve diet quality and oral health.
本横断面研究旨在探讨不同种族背景的美国学龄前儿童在达到添加糖(AS)和膳食纤维摄入建议量方面与总体饮食质量之间的关系。
来自参与1994 - 1996年及1998年个人食物摄入量持续调查(CSFII)的全国代表性学龄前儿童样本(n = 5437)的数据被分为3组:(1)达到AS摄入量建议(≤能量的10%)和膳食纤维摄入量建议(2至3岁儿童为14克,4至5岁儿童为20克;n = 236);(2)仅达到1项建议(n = 1502);(3)两项建议均未达到(n = 3699)。确定了膳食AS和膳食纤维的来源。计算了每组的平均能量摄入量、营养素摄入量和食物组密度,并采用学生t检验确定显著差异。还按4个不同种族对营养素和食物组密度进行了分层分析。
两项建议均达标的儿童饮食质量更好,但能量摄入量也高于仅达到1项建议或两项建议均未达标的儿童。
大多数美国学龄前儿童未达到AS和膳食纤维的膳食摄入建议。卫生专业人员应共同努力,提高学龄前儿童饮食中的膳食纤维密度并减少添加糖,以改善饮食质量和口腔健康。
