目的比较双标记水(DLW)报告的能量摄入量和能量消耗。此外，我们将报告的受试者人群的营养素摄入量与第三次全国健康与营养检查调查(NHANES III)中的全国调查人群数据进行了比较。设计这是一项针对儿童的横断面研究，按种族和性别平衡，主要特征为4种体型：瘦、肥胖、中心肥胖或外围肥胖。受试者/背景儿童(n=118；平均年龄=10岁)保留8天的食物记录，营养学家记录工作日学校午餐的摄入量。这些受试者在父母的帮助下，记录了所有的早餐、晚餐、零食和周末午餐。进行了统计分析，数据用一般线性模型程序进行了最小二乘方差分析。使用Tukey‘s检验对预测的治疗方法进行多重比较。结果平均每天的能量摄入被低估了能量消耗的17%到33%。漏报的倾向随着年龄的增长而增加。在所研究的所有小组和小组中都出现了报告不足的情况。报告的维生素A、维生素E、维生素B-6、钙、锌和铜的平均摄入量不到非洲裔美国女孩推荐的膳食供给量(RDA)的70%，而非洲裔美国男孩报告的铜摄入量也同样很低。平均而言，白人女孩报告的锌和铜摄入量不到RDA的70%，而白人男孩报告的铜摄入量较低(RDA的60%)。总体上报告的摄入量略低于NHANES III报告的摄入量。应用/结论营养学专业人员可以根据食物摄入量记录和其他数据修改他们给患者/受试者的营养建议。特别是对儿童来说，必须考虑到种族和性别差异，并尽可能多地说明所吃的所有食物。
Objective To compare reported energy intake with energy expenditure using doubly labeled water (DLW). Additionally, we compared reported nutrient intakes of our subject population with national survey population data from the third National Health and Nutrition Examination Survey (NHANES III).Design This was a cross-sectional study of children, balanced by race and gender, primarily characterized by 4 body types: lean, obese, centrally fat, or peripherally fat.Subjects/setting Children (n=118; mean age=10 years) kept 8-day food records, with nutritionists recording weekday school lunch intakes. These subjects, assisted by their parents, recorded all breakfasts, dinners, snacks, and weekend lunches.Statistical analyses performed Data were analyzed using least squares analysis of variance with the general linear models procedure. Tukey's test was used for multiple comparisons of predicted treatment means.Results Mean daily energy intake was underreported by 17% to 33% of energy expenditure. The tendency to underreport increased with age. Underreporting occurred in all groups and subgroups studied. Reported mean intakes of vitamin A, vitamin E, vitamin B-6, calcium, zinc, and copper were less than 70% of the Recommended Dietary Allowance (RDA) for African-American girls, whereas African-American boys reported similarly low intakes of copper. On average, white girls reported intakes less than 70% of the RDA for zinc and copper, whereas white boys reported low intakes of copper (60% of the RDA). Reported intakes in general were somewhat lower than those reported in NHANES III.Applications/conclusions Dietetics professionals may modify the nutritional advice they give to patients/subjects based on food intake records and other data. For children, particularly, it is imperative that ethnic and gender differences be taken into consideration and that all foods eaten be accounted for as much as possible.
