To our knowledge, few studies have described the usual nutrient intakes of US children aged <2 y or assessed the nutrient adequacy of their diets relative to the recommended Dietary Reference Intakes (DRIs).
We estimated the usual nutrient intake of US children aged 6-23 mo examined in NHANES 2009-2012 and compared them to age-specific DRIs as applicable.
Dietary intake was assessed with two 24-h recalls for infants aged 6-11 mo (n = 381) and toddlers aged 12-23 mo (n = 516) with the use of the USDA's Automated Multiple-Pass Method. Estimates of usual nutrient intakes from food and beverages were obtained with the use of the National Cancer Institute method. The proportions of children with intakes below and above the DRI were also estimated.
The estimated usual intakes of infants were adequate for most nutrients; however, 10% had an iron intake below the Estimated Average Requirement (EAR), and only 21% had a vitamin D intake that met or exceeded the recommended Adequate Intake (AI). More nutrient inadequacies were noted among toddlers; 1 in 4 had a lower-than-recommended fat intake (percentage of energy), and most had intakes that were below the EAR for vitamins E (82%) and D (74%). Few toddlers (<1%) met or exceeded the AI for fiber and potassium. In contrast, 1 in 2 had sodium intakes that exceeded the Tolerable Upper Intake Level (UL); ≥16% and 41% of the children had excessive intakes (greater than the ULs) of vitamin A and zinc, respectively.
The estimated usual intakes of infants were adequate for most nutrients. Most toddlers were at risk for inadequate intakes of vitamins D and E and had diets low in fiber and potassium. The sources contributing to excessive intakes of vitamin A and zinc among infants and toddlers may need further evaluation.
据我们所知,很少有研究描述2岁以下美国儿童的日常营养素摄入量,或评估其饮食相对于推荐的膳食参考摄入量(DRIs)的营养素充足性。
我们估计了2009 - 2012年美国国家健康与营养检查调查(NHANES)中6 - 23个月大儿童的日常营养素摄入量,并在适用的情况下将其与特定年龄的DRIs进行比较。
使用美国农业部的自动多次通过法,通过两次24小时膳食回顾对6 - 11个月大的婴儿(n = 381)和12 - 23个月大的幼儿(n = 516)进行膳食摄入量评估。使用美国国家癌症研究所的方法获得食物和饮料中日常营养素摄入量的估计值。还估计了摄入量低于和高于DRI的儿童比例。
婴儿的估计日常摄入量对大多数营养素来说是充足的;然而,10%的婴儿铁摄入量低于估计平均需求量(EAR),只有21%的婴儿维生素D摄入量达到或超过推荐的适宜摄入量(AI)。幼儿中发现了更多营养素摄入不足的情况;四分之一的幼儿脂肪摄入量低于推荐水平(能量百分比),大多数幼儿维生素E(82%)和维生素D(74%)的摄入量低于EAR。很少有幼儿(<1%)达到或超过纤维和钾的AI。相比之下,二分之一的幼儿钠摄入量超过了可耐受最高摄入量(UL);分别有≥16%和41%的儿童维生素A和锌摄入量过高(超过UL)。
婴儿的估计日常摄入量对大多数营养素来说是充足的。大多数幼儿有维生素D和维生素E摄入不足的风险,且膳食纤维和钾含量低。婴儿和幼儿维生素A和锌摄入过量的来源可能需要进一步评估。
