虽然已经为日本受试者开发了几种自我管理的饮食评估问卷，但它们很少用客观措施进行验证。我们使用86名大学工作人员（42名男性和44名女性，年龄范围= 24-67岁）验证了最近开发的自我管理饮食史问卷（DHQ），其中血清磷脂组分中的脂肪酸、血清中的α-和β-胡萝卜素以及α-生育酚作为金标准。海产品n-3多不饱和脂肪酸（PUFA）摄入量与年龄的Pearson偏相关系数（粗值、通过残差法的能量调整值、能量密度和脂肪密度）和血清磷脂浓度（总脂肪酸百分比）分别为0.49、0.51、0.52、0.48和0.58、0.69、0.66、0.69，摄入量（mug/d）与相应血清浓度的相关系数（μ mol/L）分别为0.43和0.40男性和0.42和0.60女性的α-和β-胡萝卜素。α-生育酚在男性中为-0.23，在女性中为-0.22。海洋来源的n-3多不饱和脂肪酸，α-和β-胡萝卜素的主要食物（g/d）的摄入量显示出相对较高的水平与相应的血清浓度的相关性，而水平一般低于与营养素摄入量的分析中观察到的。结果表明，DHQ对海洋来源的n-3多不饱和脂肪酸，α-和β-胡萝卜素摄入量进行了充分的个人排名。
Although several self-administered dietary assessment questionnaires have been developed for Japanese subjects, they have seldom been validated with objective measures. We Validated a recently developed self-administered diet history questionnaire (DHQ) with fatty acids in serum phospholipid fractions, alpha- and beta-carotenes and alpha-tocopherol in serum as a gold standard using 86 university workers (42 men and 44 women, age-range = 24-67 y). The age-adjusted Pearson partial correlation coefficients between the intakes of marine origin n-3 polyunsaturated fatty acids (PUFA) (crude values, energy-adjusted values by residual method, energy density, and fat density) and the serum phospholipid concentrations (percentage of total fatty acids) were 0.49, 0.51, 0.52, 0.48, and 0.58, 0.69, 0.66, 0.69 in men and women respectively, The correlation coefficients between intakes (mug/d) and the corresponding serum concentrations (mu mol/L) were 0.43 and 0.40 in men and 0.42 and 0.60 in women for alpha- and beta-carotene respectively. It was -0.23 in men and -0.22 in women for alpha-tocopherol. The intakes of major foods (g/d) of marine origin n-3 PUFA, alpha- and beta-carotenes showed a relatively high level of correlation with the corresponding serum concentrations, whereas the level was generally lower than those observed in the analysis with the nutrient intakes. The results suggest that DHQ ranks individual adequately for marine origin n-3 PUFA, alpha- and beta-carotene intakes.
