The authors assessed the reliability of alcohol intake as recalled from 10 years in the past in a cohort of 2,907 US adults. Participants reported their drinking habits in the First National Health and Nutrition Examination Survey interview during 1971-1975. During a follow-up interview in 1982-1984, they were asked to recall their drinking habits 10 years earlier and to report their current habits. In general, the correlation for recalled alcohol intake versus reported intake at baseline was good (r = 0.7). For all subgroups stratified by race, sex, education, smoking status, and disease status, the age-adjusted correlations for recalled alcohol intake versus baseline intake were equal to or higher than those for current alcohol intake versus baseline intake. The reliability of recall of alcohol intake in the past differs among subgroups with different age and education levels. Recalled alcohol intake was also highly correlated with current alcohol intake; in particular, current heavier drinkers tended to underestimate their previous amount of drinking, an effect that was independent of other factors. These data suggest that although recalled alcohol intake is a better predictor of past intake than are reports of current intake, current drinking habits may be an important influencing factor in the estimation of alcohol intake as recalled from the distant past.
作者评估了2907名美国成年人队列中回顾过去10年酒精摄入量的可靠性。参与者在1971 - 1975年的首次全国健康和营养检查调查访谈中报告了他们的饮酒习惯。在1982 - 1984年的随访访谈中，他们被要求回顾10年前的饮酒习惯并报告当前习惯。总体而言，回顾的酒精摄入量与基线时报告的摄入量之间的相关性良好（r = 0.7）。对于按种族、性别、教育程度、吸烟状况和疾病状况分层的所有亚组，回顾的酒精摄入量与基线摄入量的年龄调整相关性等于或高于当前酒精摄入量与基线摄入量的相关性。过去酒精摄入量回顾的可靠性在不同年龄和教育水平的亚组中有所不同。回顾的酒精摄入量也与当前酒精摄入量高度相关；特别是，当前饮酒量较大者往往低估他们以前的饮酒量，这种影响独立于其他因素。这些数据表明，虽然回顾的酒精摄入量比当前摄入量报告更能预测过去的摄入量，但当前饮酒习惯可能是影响回顾过去很长时间酒精摄入量估计的一个重要因素。
