This study sought to determine how well individuals are able to recall accurately their food habits of 24 years ago and identify those factors that are predictive of recall ability. We investigated the self-reported dietary intakes of 216 people, one-half of whom were vegetarians, including cancer cases and controls. We compared 21 key food items reported in 1960 with the same data reported in 1984. Recall ability was the highest for persons with stable diets. Vegetarian status, education, and church attendance were the other significant determinants of exact recall; age and church attendances were the only significant determinants of recall error. After excluding nonusers of particular foods, we found a positive correlation between frequency of use and recall ability.
本研究旨在确定个体能够多准确地回忆起24年前的饮食习惯，并找出那些可预测回忆能力的因素。我们调查了216人的自我报告饮食摄入量，其中一半是素食者，包括癌症病例和对照。我们将1960年报告的21种关键食物项目与1984年报告的相同数据进行了比较。饮食稳定的人的回忆能力最高。素食状况、教育程度和去教堂做礼拜是准确回忆的其他重要决定因素；年龄和去教堂做礼拜是回忆错误的唯一重要决定因素。在排除特定食物的非食用者后，我们发现使用频率与回忆能力之间存在正相关。
