项目摘要

DESCRIPTION (provided by applicant): Prevailing wisdom suggests that young children need to eat snacks to meet nutritional needs. While children consume close to a third of daily energy from snacks, there are very few empirical data on snacking among young children. Whether children need snacks to meet nutrient requirements or whether snacks put children at risk for excessive nutrition is unclear. The proposed research will use 2007-2014 National Health and Nutrition Examination Survey data to comprehensively characterize the contributions of child snacking to dietary adequacy and excess among US toddlers and preschoolers. Snacking quantity, quality, and timing will be evaluated independently (Aim 1) and as part of naturally occurring child snacking patterns (Aim 2). Child characteristics, including weight status and waist circumference, as well as family predictors of snacking behaviors will be identified (Aim 3). NHANES is uniquely suited to yield findings with high public health significance because it is the largest on-going US survey of the nutritional status of US children. Dietary Guidelines for Americans (DGA) will be used to operationally define food and nutrient outcomes of significant

描述（由申请人提供）：普遍认为幼儿需要吃零食来满足营养需求。虽然儿童每天消耗近三分之一的能量来自零食，但关于幼儿吃零食的实证数据却很少。儿童是否需要零食来满足营养需求，或者零食是否会使儿童面临营养过剩的风险，目前尚不清楚。拟议的研究将使用 2007-2014 年国家健康和营养检查调查数据来全面描述儿童零食对美国幼儿和学龄前儿童膳食充足和过量的影响。零食的数量、质量和时间将被独立评估（目标 1），并作为自然发生的儿童零食模式的一部分（目标 2）。将确定儿童特征，包括体重状况和腰围，以及家庭吃零食行为的预测因素（目标 3）。 NHANES 非常适合得出具有高度公共卫生意义的调查结果，因为它是美国正在进行的最大的美国儿童营养状况调查。美国人膳食指南 (DGA) 将用于在操作上定义重要的食物和营养结果
