The Adequate Intake (AI) values in the Dietary Reference Intakes for Japanese (DRIs-J) 2010 were mainly determined based on the median intakes from 2 y of pooled data (2005-2006) from the National Health and Nutrition Survey-Japan (NHNS-J). However, it remains unclear whether 2 y of pooled data from the NHNS-J are appropriate for evaluating the intake of the population. To clarify the differences in nutrient intakes determined from 2 and 7 y of pooled data, we analyzed selected nutrient intake levels by sex and age groups using NHNS-J data. Intake data were obtained from 64,624 individuals (age: ≥1 y; 47.4% men) who completed a semi-weighed 1-d household dietary record that was part of the NHNS-J conducted annually in Japan from 2003 to 2009. There were no large differences between the median intakes calculated from 2 or 7 y of pooled data for n-6 or n-3 polyunsaturated fatty acids (PUFAs), vitamin D, pantothenic acid, potassium, or phosphorus. When the AI values and median intakes were compared, there was no large difference in the values for n-6 or n-3 PUFAs, pantothenic acid, or phosphorus. Conversely, the AI values for vitamin D and potassium differed from the median intakes of these nutrients for specific sex and age groups, because values were not based on NHNS-J data. Our results indicate that 2 y of pooled data from the NHNS-J adequately reflect the population's intake, and that the current system for determination of AI values will be applicable for future revisions.
《2010年日本膳食营养素参考摄入量（DRIs-J）》中的适宜摄入量（AI）值主要基于日本国家健康与营养调查（NHNS-J）2005 - 2006年合并数据2年的摄入量中位数确定。然而，NHNS-J的2年合并数据是否适合评估人群摄入量仍不明确。为了阐明从2年和7年合并数据确定的营养素摄入量差异，我们使用NHNS-J数据按性别和年龄组分析了选定的营养素摄入水平。摄入数据来自64,624名个体（年龄：≥1岁；男性占47.4%），他们完成了一份半称重的1天家庭饮食记录，该记录是2003年至2009年在日本每年进行的NHNS-J的一部分。对于n-6或n-3多不饱和脂肪酸（PUFA）、维生素D、泛酸、钾或磷，从2年或7年合并数据计算出的摄入量中位数之间没有大的差异。当比较AI值和摄入量中位数时，n-6或n-3 PUFA、泛酸或磷的值没有大的差异。相反，维生素D和钾的AI值与特定性别和年龄组这些营养素的摄入量中位数不同，因为这些值并非基于NHNS-J数据。我们的结果表明，NHNS-J的2年合并数据充分反映了人群的摄入量，并且当前AI值的确定系统将适用于未来的修订。
