关于能量和营养素摄入量的个体内和个体间差异的信息对于精确估计日常饮食摄入量至关重要;然而，来自日本人群的数据有限。我们使用饮食记录来研究日本成年人能量和31种选定营养素摄入量的年龄和性别个体内和个体间差异。我们还计算了估计一组的平均摄入量所需的组大小，以及对一组内的个体进行排名和评估个体通常摄入量所需的天数，所有这些都具有适当的任意精度。一组日本女性（年轻：30-49岁，n = 58;老年：50-69岁，n = 63）和男性（年轻：30-49岁，n = 54;老年：50-76岁，n = 67）在每个季节完成4天非连续的饮食记录（共16天）。个体内变异系数和个体间变异系数在年轻组中普遍大于老年组，在男性中普遍大于女性。估计一个群体的平均摄入量所需的群体规模，以及评估一个人的日常摄入量所需的天数，对于年轻群体和男性来说一般都较大。一般来说，对女性和老年人进行排名需要更长的时间。在一组日本成年人中，个体内变异系数和个体间变异系数因年龄、性别和营养成分而异，这些变异系数用于估计充分膳食评估所需的组大小和记录数量。
Information on within- and between-individual variation in energy and nutrient intake is critical for precisely estimating usual dietary intake; however, data from Japanese populations are limited. We used dietary records to examine within- and between-individual variation by age and sex in the intake of energy and 31 selected nutrients among Japanese adults. We also calculated the group size required to estimate mean intake for a group and number of days required both to rank individuals within a group and to assess an individual’s usual intake, all with appropriate arbitrary precision. A group of Japanese women (younger: 30–49 years, n = 58; older: 50–69 years, n = 63) and men (younger: 30–49 years, n = 54; older: 50–76 years, n = 67) completed dietary records for 4 nonconsecutive days in each season (16 days in total). Coefficients of within-individual variation and between-individual variation were generally larger in the younger group than in the older group and in men as compared with women. The group size required to estimate a group’s mean intake, and number of days required to assess an individual’s usual intake, were generally larger for the younger group and for men. In general, a longer period was required to rank women and older adults. In a group of Japanese adults, coefficients of within-individual variation and between-individual variation, which were used to estimate the group size and number of records required for adequate dietary assessment, differed by age, sex, and nutrient.
