背景/目的：我们对酒精摄入量和酒精相关健康结果之间关系的了解在很大程度上取决于自我报告的酒精摄入量的有效性和可靠性。流行病学调查中经常使用每周饮酒量，但已表明受访者在正确报告整整一周的摄入量方面存在问题。本研究的目的是调查是否饮料特定的问题意味着更好的回忆，从而消除或减少先前报道的回忆期和自我报告的每周酒精摄入量之间的关联。数据来自2005年丹麦健康访谈调查，这是基于一个区域分层随机抽样的21832丹麦公民年龄≥ 16岁（答复率：67%）。通过面对面的interviews.Results收集的数据：在过去一周的每一天的酒精摄入量的饮料特定的问题并没有改变回忆期和自我报告的酒精摄入量之间的强关联。然而，当使用饮料特定问题而不是询问每天的总体酒精摄入量时，自我报告的酒精摄入量大幅增加。此外，分析表明，应避免在星期日的采访，如果目的是评估酒精摄入量的前一天（星期六）。结论：它似乎是有问题的回忆酒精摄入量，即使当召回期短至1周。当研究的主要目的是评估特定人群的平均酒精摄入量时，应主要使用每周饮酒量测量。欧洲临床营养学杂志（2011）65，520-525; doi：10.1038/ejcn.2011.1; 2011年2月16日在线发表
Background/Objectives: Our knowledge of the association between alcohol intake and alcohol-related health outcomes depends, to a large extent, on the validity and reliability of self-reported alcohol intake. Weekly drinking measures are frequently used in epidemiological surveys, but it has been shown that respondents have problems in correctly reporting intake for a full week. The aim of this study is to investigate whether a beverage-specific question implies better recall and, thereby, eliminates or diminishes the previously reported association between the recall period and the self-reported weekly alcohol intake.Subjects/Methods: The data is derived from the Danish Health Interview Survey 2005, which is based on a region-stratified random sample of 21832 Danish citizens aged >= 16 years (response rate: 67%). The data were collected via face-to-face interviews.Results: A beverage-specific question on alcohol intake on each day during the last week did not alter the strong association between the recall period and self-reported alcohol intake. However, the overall self-reported alcohol intake increased substantially when using the beverage-specific question instead of asking for the overall alcohol intake on each day. Moreover, the analyses indicated that interviews on Sundays should be avoided if the purpose is to assess alcohol intake for the previous day (Saturdays).Conclusions: It seems problematic to recall alcohol intake even when the recall period is as short as 1 week. Weekly drinking measures should primarily be used when the main aim of the study is to assess the average volume of alcohol intake in a specific population.
