自我报告的膳食摄入量数据包含有价值的信息，长期以来一直被用于制定营养计划和政策。在这种数据中总是存在一定程度的测量误差。通过确定自我报告的能量摄入量(REI)是否反映生理状态和体力活动水平来评估生物学的合理性，必须在得出关于摄入量的结论之前进行检查和说明。可以用来解释REI的可信程度的方法包括粗略的方法，例如在一系列摄入量的极端情况下排除报告EIS的参与者，以及个体化方法，例如统计调整和应用与参与者内部EI和总能量消耗(TEE)相关的误差的截止点。这些方法使研究人员能够确定报告不足和报告过多对研究结果的影响，并在利用收集的数据得出结论和解释报告的研究时适当地处理错误报告。在选择评估和说明摄入量可信程度的程序时，有许多关键的考虑因素，例如可用的资源、膳食报告工具以及每种方法的优缺点。虽然有必要进行更多的研究来推荐一种方法优于另一种方法，但研究人员应该应用一种可用的方法来解决不可信的REI问题。如果没有应用任何方法，那么至少应该报告平均TEE或REI/TEE，以便读者在总体水平上确定误报的程度，并更好地解释所提供的数据和结果。
Self-reported dietary intake data contain valuable information and have long been used in the development of nutrition programs and policy. Some degree of measurement error is always present in such data. Biological plausibility, assessed by determining whether self-reported energy intake (rEI) reflects physiological status and physical activity level, must be examined and accounted for before drawing conclusions about intake. Methods that may be used to account for plausibility of rEI include crude methods such as excluding participants reporting EIs at the extremes of a range of intake and individualized methods such as statistical adjustment and applying cutoffs that account for the errors associated with within-participant variation in EI and total energy expenditure (TEE). These approaches allow researchers to determine how accounting for under- and overreporting affects study results and to appropriately address misreporting in drawing conclusions with data collected and in interpreting reported research. In selecting a procedure to assess and account for plausibility of intake, there are a number of key considerations, such as resources available, the dietary-report instrument, as well as the advantages and disadvantages of each method. While additional studies are warranted to recommend one procedure as superior to another, researchers should apply one of the available methods to address the issue of implausible rEI. If no method is applied, then at minimum, mean TEE or rEI/TEE should be reported to allow readers to ascertain the degree of misreporting at a gross level and better interpret the data and results provided.
