背景：对于美国儿童总饮水量与饮食特征之间的关系知之甚少。目的：我们研究了儿童和青少年的总饮水量及其贡献者及其与饮食和膳食报告的关系。设计：使用2005-2006年国家健康与营养调查中2-19岁儿童的饮食数据（n = 3978）来计算通常的总饮水量。利用多元回归分析，考察了总水量及其贡献因子与社会人口学特征、饮食和膳食属性的关系。结果：2-5岁、6-11岁和12-19岁美国人调整后的总饮水平均摄入量分别为1.4 L、1.6 L和2.4 L。平均每日总摄取量一般少于适当摄取量；总的来说，更多的男孩报告摄入了至少足够的摄入量。白开水占总饮水量的比例随着年龄的增长而增加。普通水摄入量与饮料水分摄入量和食物能量密度呈负相关；相反，饮料水分与膳食能量、脂肪和食物的能量密度呈正相关。在不同年龄组中，供水量与膳食模式（进食次数、早餐或零食的报告）之间的关联并不一致。据报道，主餐中含有近80%的食物水分，约66%的饮料水分和约30%的白开水。结论：24小时内不同贡献者的总饮水量因年龄而异。在回忆中观察到与白开水和饮料水分量相关的饮食摄入量的质的差异。美国儿童和青少年每天的饮料有三分之二以上是在正餐时饮用的。中华临床医学杂志，2010;32(2):391 - 391。
Background: Little is known about the association of contributors of total water intake with dietary characteristics in US children.Objective: We examined intakes of total water and its contributors and their associations with diet and meal reporting in children and adolescents.Design: Dietary data for children 2-19 y of age (n = 3978) from the National Health and Nutrition Examination Survey 2005-2006 were used to compute usual intake of total water. The association of total water and its contributors with sociodemographic characteristics and dietary and meal attributes was examined by using multiple regression analysis.Results: The adjusted mean intakes of total water in Americans aged 2-5, 6-11, and 12-19 y were 1.4, 1.6, and 2.4 L, respectively. The mean usual intake of total water was generally less than the Adequate Intake; overall, more boys reported intakes of at least the Adequate Intake. The percentage of total water intake from plain water increased with age. Plain water intake was inversely associated with the intake of beverage moisture and the energy density of foods; conversely, beverage moisture was positively associated with dietary energy, fat, and the energy density of foods. Associations of water contributors with meal patterns (number of eating occasions, reporting of breakfast or snack) were inconsistent across age groups. Nearly 80% of food moisture, >66% of beverage moisture, and approximate to 30%] of plain water were reported with main meals.Conclusions: Intake of total water over 24 h from different contributors varied by age. Qualitative differences in dietary intake in association with the amount of plain water and beverage moisture in the recalls were observed. American children and adolescents consumed more than two-thirds of their daily beverages with main meals. Am J Clin Nutr 2010;92:887-96.
