VALADATION OF MULTIPLE PASS 24 HOUR RECALL METHOD

这项研究的目的是确定能量摄入量(Ei)的预测因素。 在35名低收入、体重稳定的美国女性样本中的错误报告(平均 30岁，19-46岁)。总能量消耗(TEE)由 双标水法(DLW)14天；EI四次，多次通过 使用二维食物的24小时饮食回忆(2个面对面，2个电话) 食物摄入量分析中估计份量大小的模型 得克萨斯大学系统(FIAS)；通过广泛的成就来识字 测试(WRAT)；和双能X射线吸收法测定身体成分 (DXA)。平均EI显著低于平均TEE(2197±607比2644 +503千卡，p=.001)。错误报告被定义为EI-TEE(平均值-447+697 KCAL)，并与WRAT评分(r=+0.46**)、体脂百分比相关 (r=-0.45**)和家庭成员数(r=-0.35*)。WRAT分数 与体脂百分比呈负相关(r=-0.55**)。vbl.使用 多元回归分析，WRAT得分解释显著 错误报告的差异超过了正文百分比的影响 FAT(R=0.52**)。EI以下(n=12)、有效(n=22)和过量(n=1)记者 分别定义为Ei：tet；0.71，0.71-1.29，&gt；1.29。这个 不记名记者的WRAT得分显著低于 EI的有效记者(1027+35比1045+21，p=0.05)。在此示例中， 美国低收入女性的阅读和拼写能力 WRAT，提高了他们回忆食物摄入量的准确性。未来 计划包括通过问卷调查样本，试图 解释能量摄入的心理和行为决定因素 报道不足。

The aim of this study was to determine predictors of energy intake (EI) misreporting in a sample of 35 low-income, weight stable U.S. women (mean age 30, range 19-46). Total energy expenditure (TEE) was measured by the doubly labeled water method (DLW) over 14 days; EI by four, multiple-pass 24-h diet recalls (2 in-person, 2 by telephone) using 2-dimensional food models to estimate portion sizes and analyzed by the Food Intake Analysis System (FIAS) of the Univ of Texas; literacy by the Wide Range Achievement Test (WRAT); and body composition by dual energy X-ray absorptiometry (DXA). Mean EI was significantly lower than mean TEE (2197 + 607 vs. 2644 + 503 kcal, p=.001). Misreporting was defined as EI-TEE (mean -447 + 697 kcal) and was associated with WRAT scores (r=+0.46**), percent body fat (r=-0.45**), and the number of household members (r=-0.35*). WRAT scores and percent body fat were negatively associated (r=-0.55**). Using multiple regression analysis, WRAT scores explained a significant amount of the variation in misreporting over and above the effect of percent body fat (R=0.52**). Under (n=12 ), valid (n=22) and overreporters (n=1) of EI were defined as EI:TEE <0.71, 0.71-1.29, >1.29 respectively. The underreporters had significantly lower WRAT scores in comparison with the valid reporters of EI (1027 + 35 vs. 1045 + 21, p=.05). In this sample of U.S. low-income women, the ability to read and spell as measured by the WRAT, improved the accuracy of their recall of their food intake. Future plans include surveying the sample by questionnaire in an attempt to explain the psychological and behavioral determinants of energy intake underreporting.
