目的：评估使用简短食物频率问卷（FFQ）测量的脂肪酸（FA）消耗数据与通过分析血浆FA水平获得的数据的相对有效性。设计：在这项横断面研究中，2001年8月在日本从177名中年成年人（92名男性和85名女性）中获得了完整的FFQ。使用FFQ评估FA摄入量，并根据空腹血浆FA水平验证这些值。结果：男性和女性的总脂肪酸摄入量分别为44.48.0g/d和42.97.2g/d。男性平均血浆TFA水平为12.73 ± 3.78 mmol/L，女性为10.54 ± 1.75 mmol/L。n-3高度不饱和脂肪酸（HUFAs）的斯皮尔曼等级相关系数（校正或不校正能量摄入）为0.37（P
Objective: To assess the relative validity of consumption data for fatty acids (FAs) measured using a short food frequency questionnaire (FFQ) in comparison with those obtained by analysis of plasma FA levels. Design: In this cross-sectional study, completed FFQs were obtained from 177 middle-aged adults (92 men and 85 women) in Japan during August 2001. FA intake was assessed using the FFQ, and the values were validated against fasting plasma FA levels. Results: The meanSD daily intake of total fatty acids (TFAs) was 44.48.0 g/day for men, and 42.97.2 g/day for women. The mean plasma TFA level was 12.733.78 mmol/litre for men, and 10.541.75 mmol/litre for women. Spearman's rank correlation coefficients (adjusted or not for energy intake) for n-3 highly unsaturated fatty acids (HUFAs) were 0.37 (P
