为了确定老年疾病与饮食摄入之间的关联，需要验证老年人的食物频率问卷（FFQ）。我们比较了老年人群中膳食记录 (DR) 和 FFQ 的能量和营养摄入量，并将数据与之前研究中中年人（30-68 岁）的结果进行了比较。目前的参与者包括 65 名女性和 78 名男性（65-88 岁），他们在京都-龟冈研究的一个亚群中完成了 FFQ 和 7 天 DR。我们的FFQ是为中年人创建的。为了验证 FFQ，我们通过比较当前研究和之前研究之间的相关系数来研究等效精度。在当前和之前的研究中，女性 DR 和 FFQ 之间的能量和营养摄入相关性中位数分别为 0.24 和 0.30 (p = 0.329)，男性为 0.24 和 0.28 (p = 0.399)。这些摄入量的 FFQ 与 DR 的中位数比率也相似。与之前在中年人群中的研究结果相比，老年人能量和营养摄入的 FFQ 的准确性和精确度没有差异。还需要一项使用恢复生物标志物评估能量和营养摄入量的验证研究。
To determine the association between geriatric disorders and dietary intake, validation of a food frequency questionnaire (FFQ) for elderly individuals is needed. We compared energy and nutrient intakes derived from dietary records (DR) and FFQ in an elderly population and compared the data against results from middle-aged individuals (30-68 years) from a previous study. Current participants included 65 women and 78 men (65-88 years) who completed FFQ and 7-day DR in a subpopulation of the Kyoto-Kameoka study. Our FFQ was created for middle-aged individuals. To validate the FFQ, we investigated equivalent precision by comparing the correlation coefficients between the present and previous study. Median correlations for energy and nutrient intake between the DR and FFQ in the current and previous studies were 0.24 and 0.30 (p = 0.329) in women and 0.24 and 0.28 (p = 0.399) in men, respectively. The median ratio of FFQ to DR for these intakes were also similar. The accuracy and precision of the FFQ for energy and nutrient intake in elderly individuals did not differ compared with previous findings in a middle-aged population. A validation study evaluating energy and nutrient intake using recovery biomarkers is further needed.
