Recall of past alcohol intake is used in many studies of chronic disease, but few studies have been able to examine its long-term reliability.
We sought to assess the reliability of recalled alcohol intake assessed at an average age of 70 years in 2001, after 15 and 23 years of follow-up, in a prospective study of medical students in classes 1948 to 1964.
Average reported alcohol intake 15 years and 23 years prior were 6.3 and 7.4 drinks per week, respectively. Recall of alcohol intake overestimated the concurrently reported intake after 15 years by a mean of 0.47 (95% CI [0.10, 0.85]) drinks per week and underestimated intake after 23 years by a mean of 0.79 (95% CI [-1.27, -0.30]) drinks per week, mostly driven by differences between concurrently reported and recalled distilled spirits consumption. Characteristics associated with underestimation of alcohol recall were age of 71 years or older in 2001, self-report of memory difficulties, and self-report of difficulties in physical functioning. In multivariate regression analyses combining 15- and 23-year recall, subjects who reported consumption of more than 14 alcoholic drinks per week in 2001 marginally overestimated recall by slightly more than 1 drink per week (M = 1.18 drinks/week, 95% CI [-0.03, 2.40]).
Although significant differences were detected, recalled alcohol intake after 15 and 23 years of follow-up is remarkably reliable.
在许多慢性病研究中都使用过去饮酒量的回忆，但很少有研究能够检验其长期可靠性。
我们试图评估在 1948 年至 1964 年期间入学的医学生前瞻性研究中，2001 年平均年龄为 70 岁时评估的过去饮酒量的可靠性，随访 15 年和 23 年后。
分别为 15 年前和 23 年前报告的平均饮酒量为 6.3 杯和 7.4 杯/周。与 15 年前相比，饮酒量的回忆平均高估了 0.47 杯/周（95%置信区间[0.10，0.85]），与 23 年前相比，平均低估了 0.79 杯/周（95%置信区间[-1.27，-0.30]），主要是由于同时报告的和回忆的蒸馏酒消耗之间的差异。与酒精回忆低估相关的特征是 2001 年年龄为 71 岁或以上、自我报告记忆力困难以及自我报告身体机能障碍。在结合了 15 年和 23 年回忆的多变量回归分析中，2001 年报告每周饮用超过 14 份含酒精饮料的受试者回忆时略微高估了略多于 1 杯/周（M = 1.18 杯/周，95%置信区间[-0.03，2.40]）。
尽管检测到显著差异，但 15 年和 23 年随访后的回忆饮酒量具有显著可靠性。
