本研究旨在确定第二次全国健康和营养检查调查 (NHANES II) 中 11,663 名参与者的膳食摄入量明显漏报的情况和程度。将自我报告的饮食摄入量与估计的基础代谢率进行比较。少报是基于确定成年人能量消耗合理水平的截止限度。结果表明，该样本中高达 31% 的成年人可能低估了饮食摄入量。那些最有漏报风险的人受教育程度较低且体重较重。性别×种族交互作用表明，对于两个种族类别，女性比男性更有可能漏报，但白人参与者中男性和女性之间的差异更大。结论是，能量需求减少、故意伪造和饮食评估中固有的测量误差等因素导致了明显的漏报，并且这种情况发生在很大一部分饮食数据中。
The present study sought to identify the presence and degree of apparent underreporting of dietary intake in 11,663 participants in the Second National Health and Nutrition Examination Survey (NHANES II). Self-reported dietary intake was compared with estimated basal metabolic rate. Underreporting was based on cutoff limits that identified plausible levels of energy expenditure for adult individuals. Results indicated that up to 31% of adults in this sample may have underreported dietary intake. Those individuals at greatest risk of underreporting were less well educated and heavier. The Sex× Race interaction indicated that for both ethnic categories, women were more likely to underreport than men, but the difference between men and women was greater among Caucasian participants. It is concluded that such factors as reduced energy needs, deliberate falsification, and measurement error inherent in dietary assessment contribute to apparent underreporting, and this occurs in a large percentage of dietary data.
