目的：将低能记者和非低能记者的食物报道分为四个方面--报道某一特定食物的倾向、每个使用者的报告频率、每次提到的份量和定性的(低脂？低糖、低能量)报告的差异--以确定它们之间的区别。评估方法：两次不连续的24小时饮食召回。低能量报告的定义是能量摄入量低于估计的基础代谢率的80%。背景：家庭个人访谈。受试者：8334名成年人，来自分层的、多阶段的区域概率样本，旨在代表居住在美国家庭的非住院患者。结果：在所有不同类型的食物中，Lers不太可能报告的食物类别(44个食物类别中的28个)，他们报告时较少报告的食物类别(44个类别中的15个)，以及他们报告的数量较少的那些(44个类别中的26个)。食物选择的质量差异--即脂肪、糖和/或能量含量的差异--并不是很普遍(24个食物类别中有4个)。结论：此类分析的实际应用是改进饮食数据的收集方法，以便减少这种偏差。需要进一步的方法学研究，以减少受访者忽略提到食物和低估分量大小的可能性。
Objective: To partition the food reports of low energy reporters (LERs) and non-LERs into four aspects-tendency to report a given food, frequency of reports per user, portion sizes per mention, and the qualitative (low-fat? low-sugar, low-energy) differences of the reports - in order to determine what differentiates them from one another.Assessment method: Two non-consecutive 24h dietary recalls. Low energy reporting was defined as energy intake lower than 80% of estimated basal metabolic rate.Setting:In-home personal interviews.Subjects: 8334 adults from a stratified, multi-stage area probability sample designed to be representative of noninstitutionlized persons residing in households in the United States.Results: Across all different types of foods, there are those food groups which LERs are less likely to report (28 of 44 food groups), those which they report less frequently when they do report them (15 of 44 groups), and those for which they report smaller quantities per mention (26 of 44). Qualitative differences in the food choices - that is, differences in fat, sugar, and/or energy content-were not so widespread (4 of 24 food groups).Conclusions: The practical application of analyses such as these is to improve the methods of gathering dietary data so that this kind of bias can be reduced. Further methodological research is needed to reduce the likelihood of respondents neglecting to mention foods and underestimating portion sizes.
