为了支持研究，并为食品和营养从业者提供基于营养的咨询的坚实基础，需要负担得起的自动24小时饮食回忆。需要多天的摄入量，沿着随着时间的推移重复报告，以实现个体摄入量的稳定指标，并支持对满足饮食目标的成功进行评价，因为个体内摄入量存在差异。关于受试者反应、参与率和24小时重复召回的感知受试者负担的信息很少。我们的目的是确定受试者的意愿进行8个24小时召回通过Internet.Design一项研究，以验证一个基于Web的，自动化的，自我管理的24小时召回（饮食日，Centrax公司，芝加哥，IL）。主题/设置二百六十一个白色和非洲裔美国人的主题在50英里内的加州大学洛杉矶分校参加了这项研究。受试者在研究访视时完成3天饮食日，并自行完成另外5天。最后2个饮食日在最终门诊访视后1个月和2个月完成。受试者被通知的自动电子邮件的DietDay完成的需要，和nonresponders进行了个性化的电子邮件和电话calls.Results后续的感知受试者的负担是最小的，即使在完成6次召回，92%愿意继续报告他们的日常饮食1和2个月后。白色受试者的返回率略高，94%的受试者完成了所有8次回忆，而非裔美国人的这一比例为91%。参与者能够在家中、办公室、图书馆或朋友或家人的家中访问互联网。这也是有趣的是，82%的受试者认为，24小时的回忆是上级的饮食史，反映他们的正常diet.Conclusion这些结果开辟了新的机会，食品和营养从业者，以加强他们的营养咨询，在一个有效的和负担得起的方式，而无需额外的时间投资。美国饮食协会杂志2010;110：857-864。
Objective To support research and to provide food and nutrition practitioners with a strong foundation for nutrient-based counseling, there is a need for affordable automated 24-hour dietary recalls. Multiple days of intake, along with repeated reports over time, are needed to achieve stable indicators of individual intakes and to support evaluation of success in meeting dietary goals because of intraindividual intake variability. Little information has been published on subject responses, participation rates, and the perceived subject burden of repeated 24-hour recalls. Our aim was to determine the willingness of subjects to conduct eight 24-hour recalls via the Internet.Design A study to validate a Web-based, automated, self-administered 24-hour recall (Diet Day, Centrax Corporation, Chicago, IL).Subjects/setting Two-hundred and sixty-one white and African-American subjects within 50 miles of the University of California-Los Angeles participated in the study. Subjects completed 3 DietDays at the study visits and another 5 days on their own. The last 2 DietDays were completed 1 and 2 months after the final clinic visit. Subjects were notified by automatic e-mail of the need for DietDay completion, and nonresponders were followed up with personalized e-mails and phone calls.Results The perceived subject burden was minimal and, even after completing six recalls, 92% were willing to continue reporting their daily diets 1 and 2 months later. White subjects had a slightly higher rate of return, with 94% completing all eight recalls, compared to 91% of African-American subjects. Participants were able to access the Internet in their homes, offices, library, or homes of friends or family. It is also of interest that 82% of subjects believed the 24-hour recall was superior to a diet history in reflecting their normal diet.Conclusion These results open up new opportunities for food and nutrition practitioners to strengthen their nutritional counseling in an efficient and affordable manner without additional time investment.
