The Automated Self-Administered 24-hour Recall (ASA24), a freely available Web-based tool, was developed to enhance the feasibility of collecting high-quality dietary intake data from large samples.
The purpose of this study was to assess the criterion validity of ASA24 through a feeding study in which the true intake for 3 meals was known.
True intake and plate waste from 3 meals were ascertained for 81 adults by inconspicuously weighing foods and beverages offered at a buffet before and after each participant served him- or herself. Participants were randomly assigned to complete an ASA24 or an interviewer-administered Automated Multiple-Pass Method (AMPM) recall the following day. With the use of linear and Poisson regression analysis, we examined the associations between recall mode and 1) the proportions of items consumed for which a match was reported and that were excluded, 2) the number of intrusions (items reported but not consumed), and 3) differences between energy, nutrient, food group, and portion size estimates based on true and reported intakes.
Respondents completing ASA24 reported 80% of items truly consumed compared with 83% in AMPM (P = 0.07). For both ASA24 and AMPM, additions to or ingredients in multicomponent foods and drinks were more frequently omitted than were main foods or drinks. The number of intrusions was higher in ASA24 (P < 0.01). Little evidence of differences by recall mode was found in the gap between true and reported energy, nutrient, and food group intakes or portion sizes.
Although the interviewer-administered AMPM performed somewhat better relative to true intakes for matches, exclusions, and intrusions, ASA24 performed well. Given the substantial cost savings that ASA24 offers, it has the potential to make important contributions to research aimed at describing the diets of populations, assessing the effect of interventions on diet, and elucidating diet and health relations. This trial was registered at clinicaltrials.gov as NCT00978406.
自动自填式24小时膳食回顾法（ASA24）是一种免费的基于网络的工具，旨在提高从大样本中收集高质量膳食摄入数据的可行性。
本研究的目的是通过一项喂养研究评估ASA24的标准效度，该研究中三餐的实际摄入量是已知的。
通过在自助餐时不显眼地称量每位参与者取用食物和饮料前后的重量，确定81名成年人三餐的实际摄入量和盘中剩余量。参与者被随机分配在第二天完成一份ASA24或由访谈员实施的多轮自动膳食回顾法（AMPM）。通过线性和泊松回归分析，我们研究了回顾方式与以下方面的关联：1）报告匹配且被排除的已消费项目的比例，2）虚报项目（报告但未消费的项目）的数量，以及3）基于实际摄入量和报告摄入量的能量、营养素、食物类别和份量估计值之间的差异。
完成ASA24的受访者报告了80%的实际消费项目，而在AMPM中这一比例为83%（P = 0.07）。对于ASA24和AMPM，多成分食品和饮料中的添加物或成分比主要食品或饮料更常被遗漏。ASA24中的虚报项目数量更高（P < 0.01）。在实际摄入量与报告的能量、营养素和食物类别摄入量或份量之间的差距方面，几乎没有发现回顾方式造成差异的证据。
尽管由访谈员实施的AMPM在匹配、排除和虚报方面相对于实际摄入量表现稍好，但ASA24表现良好。鉴于ASA24能大幅节省成本，它有潜力为旨在描述人群饮食、评估干预措施对饮食的影响以及阐明饮食与健康关系的研究做出重要贡献。该试验在clinicaltrials.gov上注册，注册号为NCT00978406。
