The relative validity of a 104-item food-frequency method to assess intakes of fats and cholesterol was tested against the dietary history of 191 men and women. Pearson correlation coefficients ranged from 0.38 for linoleic acid (% of energy) to 0.83 for energy intake, with 0.78 and 0.75 for the intakes of total fat and saturated fatty acids, respectively. Mean intakes were overestimated by the food-frequency questionnaire relative to the dietary history by 5% for energy and monounsaturated fatty acids (% of energy) and up to 30% for linoleic acid intake. Linoleic acid concentrations in erythrocytes and adipose tissue were used as biomarkers of intake. The correlation of the linoleic acid intake according to the food-frequency questionnaire with linoleic acid in erythrocytes and adipose tissue was 0.44 and 0.28, respectively, and the dietary history gave similar values. The food-frequency questionnaire gives results similar to those from the dietary history and is thus considered appropriate for classifying subjects according to their fat intake.
针对191名男性和女性的饮食史，对一种包含104个条目的食物频率法评估脂肪和胆固醇摄入量的相对有效性进行了测试。皮尔逊相关系数范围从亚油酸（能量的百分比）的0.38到能量摄入量的0.83，总脂肪和饱和脂肪酸摄入量的相关系数分别为0.78和0.75。相对于饮食史，食物频率问卷高估了能量和单不饱和脂肪酸（能量的百分比）的平均摄入量5%，亚油酸摄入量高估了30%。红细胞和脂肪组织中亚油酸浓度被用作摄入量的生物标志物。根据食物频率问卷得出的亚油酸摄入量与红细胞和脂肪组织中亚油酸的相关性分别为0.44和0.28，饮食史得出的数值相似。食物频率问卷得出的结果与饮食史相似，因此被认为适合根据受试者的脂肪摄入量对其进行分类。
