背景：全国食物摄入量调查依靠 24 小时饮食回忆法来评估美国人的营养摄入量。 目的：这项观察性验证研究是在受控条件下进行的，旨在测试美国农业部 (USDA) 5 步多次通过饮食回忆法的有效性；测试正常体重、超重和肥胖女性回忆食物摄入量的能力；设计：年龄 21-65 岁、体重指数（kg/m(2)）为 20-45 的女性（n = 49）在 1 天内从多种食物中选择所有正餐和零食。第二天，通过电话进行了 24 小时饮食回顾，采用美国农业部 5 步多次通过法。方差和协方差分析测试了记忆的整体准确性以及 BMI 对饮食记忆的影响。结果：作为一个群体，女性高估了她们的能量和碳水化合物摄入量 8-10%。在肥胖女性中，未观察到平均实际摄入量和回忆摄入量的能量和常量营养素之间存在显着差异。正常体重和超重女性显着（P < 0.01）高估了她们的能量、蛋白质和碳水化合物摄入量。在所研究的 BMI 范围内，回忆的脂肪摄入量与实际摄入量没有显着差异。结论：美国农业部 5 步多次通过法有效评估了平均能量摄入量，其误差在前一天平均实际摄入量的 10% 范围内。尽管在研究当天饮食不足，但肥胖女性比超重和正常体重女性更准确地回忆起食物摄入量。
Background: National surveys of food intake rely on the 24-h dietary recall method for assessing the nutrient intakes of Americans.Objectives: This observational validation study was conducted under controlled conditions to test the effectiveness of the US Department of Agriculture (USDA) 5-step multiple-pass method for dietary recall; to test the ability of normal weight, overweight, and obese women to recall food intake; and to test the accuracy of macronutrient recall.Design: Women (n = 49) aged 21-65 y with a body mass index (in kg/m(2)) of 20-45 selected all meals and snacks for 1 d from a wide variety of foods. A 24-h dietary recall with the use of the USDA 5-step multiple-pass method was administered by telephone the following day. Analysis of variance and covariance tested the overall accuracy of recall and the effect of BMI on dietary recall.Results: As a population, the women overestimated their energy and carbohydrate intakes by 8-10%. No significant differences between mean actual and recalled intakes of energy and the macronutrients were observed in the obese women. Normal-weight and overweight women significantly (P < 0.01) overestimated their energy, protein,, and carbohydrate intakes. Recalled fat intake was not significantly different from actual intake in women across the BMI range studied.Conclusions: The USDA 5-step multiple-pass method effectively assessed mean energy intake within 10% of mean actual intake on the previous day. Obese women more accurately recalled food intake than did overweight and normal-weight women despite undereating on the day of the study.
