目的：验证一种新的食物频率问卷 (FFQ)，用于测量参与挪威母婴队列研究 (MoBa) 的妇女报告的水果、蔬菜和茶的摄入量。设计：将 FFQ 估计的水果、蔬菜和茶的摄入量与通过 4 天称重食物日记 (FD) 测量的尿类黄酮排泄量、血浆类胡萝卜素浓度和摄入量进行比较。应用三角法使用两个独立的生物标志物计算 FFQ 有效性系数。 背景和受试者： 119 名参与 MoBa 的女性。 结果：水果摄入量的 FFQ 估计值与尿根皮素 (r = 0.33)、柑橘类水果/果汁与尿橙皮素 (r = 0.44)、煮熟的蔬菜与血浆 α-胡萝卜素 (r = 0.37) 以及茶与尿显着相关山奈酚 (r = 0.41)（所有 P < 0.01）。平均而言，按 FFQ 和生物标志物分类时，60% 的参与者属于相同或相邻的五分位数。水果 (r = 0.39)、蔬菜 (r = 0.34)、三元果汁 (r = 0.50) 和茶 (r = 0.53) 的 FFQ 和 FD 之间存在显着相关性。通过三角法计算，柑橘类水果/果汁的 FFQ 有效性系数为 0.65，熟蔬菜的 FFQ 有效性系数为 0.59。 结论：验证研究表明，MoBa FFQ 可用于估计挪威孕妇的水果、果汁、蔬菜和茶摄入量，并对分布内的个体进行排名。
Objective: To validate a new food-frequency questionnaire (FFQ) for measuring the intake of fruit, vegetables and tea reported by women participating in the Norwegian Mother and Child Cohort Study (MoBa).Design: Intake of fruits, vegetables and tea estimated by the FFQ was compared with urinary flavonoid excretion, plasma carotenoid concentration and intake measured by a 4-day weighed food diary (FD). The triangular method was applied to calculate FFQ validity coefficients using two independent biomarkers.Setting and Subjects: One hundred and nineteen women participating in MoBa.Results: The FFQ estimate of fruit intake was significantly correlated with urine phloretin (r = 0.33), citrus fruit/juice with urine hesperetin (r = 0.44), cooked vegetables with plasma alpha-carotene (r = 0.37), and tea with urine kaempferol (r = 0.41) (P < 0.01 for all). On average, 60% of the participants fell into the same or adjacent quintiles when classified by FFQ and biomarkers. Significant correlations between the FFQ and FD were found for fruit (r = 0.39), vegetables (r = 0.34), juices of triads (r = 0.50) and tea (r = 0.53). The FFQ validity coefficient was 0.65 for citrus fruit/juice and 0.59 for cooked vegetables as calculated by the triangular method.Conclusions: The validation study shows that the MoBa FFQ can be used to estimate fruit, juice, vegetable and tea intake in pregnant Norwegian women, and to rank individuals within the distribution.
