背景技术背景：在日本，用于测量普通民众宏量和微量营养素摄入量的简短食物频率问卷（FFQ）的验证研究尚未完全执行。方法：2004年2月，日本艾希县的202名中年日本人（73名男性和129名女性）完成了FFQ和3天称重饮食记录（3d-WDR）。我们将FFQ计算的能量和26种营养素的摄入量与3d-WDR作为参考。结果：用FFQ确定的所选营养素的平均每日摄入量通常低于3d-WDR。使用FFQ vs. 3d-WDR（最小值-中位数-最大值）评估的比值分布范围为0.57 - 0.79 - 1.09（男性）和0.61 - 0.86 - 1.04（女性）。对于男性，用两种设备定量的所选营养素摄入量之间的去衰减、对数转换和能量调整Pearson相关系数分布在0.12 - 0.45 - 0.86之间，能量调整斯皮尔曼等级相关系数分布在0.13 - 0.35 - 0.76之间。女性的相应值为0.10 - 0.38 - 0.66和0.11 - 0.34 - 0.47。准确的协议，在相邻类别的协议，并根据四分位数分类与两种方法测量的能量调整后的营养摄入量的分歧的中位数百分比分别为33，74，和5男性，和35，76，和7女性，分别。结论：与3d-WDR相比，FFQ计算的大多数营养素摄入量的相对有效性指数较高。因此，该问卷似乎适用于分类个人根据消费的能量和选定的营养素在饮食研究的中年日本人。
BACKGROUND: Validation studies on brief food frequency questionnaires (FFQs) for measuring consumption of macro- and micro-nutrients for the general populace are not fully executed in Japan. METHODS: Two hundred and two middle-aged Japanese (73 males and 129 females) in Aich Prefecture, Japan completed an FFQ and 3day-weighed diet records (3d-WDRs) in February 2004. We compared intakes of energy and 26 nutrients computed with the FFQ against those with the 3d-WDRs as a reference. RESULTS: Mean daily intakes of selected nutrients determined with the FFQ were generally less than those with 3d-WDRs. The ratios assessed with the FFQ vs. 3d-WDRs (minimum - median - maximum) were distributed from 0.57 - 0.79 - 1.09 for males, and 0.61 - 0.86 - 1.04 for females. De-attenuated, log-transformed and energy-adjusted Pearson’s correlation coefficients between intakes of selected nutrients quantified with both devices were distributed from 0.12 - 0.45 - 0.86 and energy-adjusted Spearman’s rank correlation coefficients were from 0.13 - 0.35 - 0.76, for males. The respective values for females were 0.10 - 0.38 - 0.66, and 0.11 - 0.34 - 0.47. Median percentages for exact agreement, agreement within adjacent categories, and disagreement according to quartile classification of the energy-adjusted nutrient intakes measured with both methods were 33, 74, and 5 for males, and 35, 76, and 7 for females, respectively. CONCLUSION: Satisfactorily high relative validity indices of most nutrient intakes computed with the FFQ were attained against those with the 3d-WDRs. The questionnaire therefore appears applicable for categorizing individuals according to consumption of energy and selected nutrients in dietary studies of middle-aged Japanese.
