项目摘要

Measurement of dietary intake is a central component of nutrition research. However, a variety of measurement errors in virtually all methods of dietary assessment suggest a cautious interpretation of dietary data. The sources of error may be systematic or random. There has been increasing recognition of underreporting of food intake in dietary surveys as a source of measurement error. Dietary intakes obtained from all self-reported methods of dietary assessment--24-hour recalls, records, history, and food frequency questionnaires--have been shown to be underestimates of energy intake. Limited information on who is more likely to underreport is also available. For example, women and overweight individuals were more likely to underreport food intake in some studies. However, little is known about what is underreported. Because underreporting of food intake can bias results of studies focusing on diet and disease relationships, it is an important area of investigation. The purpose of this small grant proposal is to examine nationally representative data to determine the nature of underreporting. The study will use dietary data from the third National Health and Nutrition Examination Survey (NHANES III), 1988-1994 (n=15,979), to determine what is underreported. The specific aims of this study are to determine whether food group intake or eating behaviors of dietary underreporters differ from those of adequate reporters. The significance of the proposed research is that findings of this study will help in: 1) strategies for improving dietary assessment methods, and 2) interpretation of results from analytic epidemiology studies relating food intake to disease by providing information on what kinds of foods are likely to be underreported.

膳食摄入量的测量是营养的核心组成部分研究。然而，几乎所有测量都存在各种测量误差饮食评估方法建议谨慎解释饮食数据。误差源可能是系统性的，也可能是随机性的。那里人们越来越认识到，人们对食物摄入量的少报饮食调查是测量误差的一个来源。膳食摄入量从所有自我报告的饮食评估方法中获得--24小时回忆、记录、历史和食物频率调查问卷——已表明低估了能量摄入。关于谁的信息有限更有可能漏报也可。例如，妇女和超重的人更有可能少报食物摄入量一些研究。然而，人们对漏报的情况知之甚少。因为少报食物摄入量可能会导致研究结果出现偏差关注饮食和疾病的关系，这是一个重要领域调查。这项小额赠款提案的目的是审查具有全国代表性的数据来确定少报。该研究将使用第三次全国饮食数据健康与营养检查调查 (NHANES III)，1988-1994 (n=15,979)，以确定漏报的内容。具体目标这项研究的目的是确定食物组的摄入量或饮食是否饮食低报者的行为与充分报道者的行为不同记者。拟议研究的意义在于发现这项研究将有助于：1）改善饮食的策略评估方法，以及 2) 对分析结果的解释通过提供有关食物摄入与疾病的流行病学研究关于哪些种类的食品可能被漏报的信息。
