我们在日本公共卫生中心前瞻性（JPHC）研究中评估了中年日本成年人使用食物频率问卷（FFQ）估计糖摄入量的有效性和再现性。在JPHC研究的子样本中（多个地区的队列I和II），我们计算了FFQ结果与尿糖浓度和饮食记录（DR）的斯皮尔曼相关性的有效性;我们评估了两个FFQ之间的相关性的可重复性。1994-1998年期间，（队列I：n = 27 [男性]，n = 45 [女性]）（春季和秋季）每个季节24小时尿样和完成7个传唤日DR（I：n = 99，n = 113; II：n = 168，n = 171）和每年间隔的两次FFQ（147种食物）（I：n = 101，n = 108; II：n = 143，n = 146）。来自FFQ的糖摄入量与尿糖相关（去衰减相关性：0.40; 95%CI：0.19，0.58）。调整社会人口统计学和生活方式变量后，男性和女性的FFQ和DR之间的相关性分别为0.57（0.42，0.69）和0.41（0.24，0.55）（I）和0.56（0.44，0.65）和0.34（0.20，0.47）（II）。男性和女性的FFQ之间的相关性分别为0.63（0.49，0.73）和0.55（0.41，0.67）（I）和0.66（0.55，0.74）和0.63（0.52，0.72）（II）。总之，我们的研究显示中等FFQ有效性和再现性的糖摄入量评估。
We evaluated the validity and reproducibility of estimated sugar intakes using a food frequency questionnaire (FFQ) among middle-aged Japanese adults in the Japan Public Health Centre-Based Prospective (JPHC) study. In subsamples of the JPHC study (Cohorts I and II in multiple areas), we computed Spearman's correlations of FFQ results with urine sugar concentrations and dietary records (DR) for validity; we evaluated correlations between two FFQs for reproducibility. During 1994-1998, participants (Cohort I: n = 27 [men], n = 45 [women]) provided two (spring and fall) 24-h urine samples and completed 7-consecutive-day DR per season (I: n = 99, n = 113; II: n = 168, n = 171) and two FFQs (147 food items) at yearly intervals (I: n = 101, n = 108; II: n = 143, n = 146). Sugar intakes from FFQ were correlated with urinary sugar (de-attenuated correlations: 0.40; 95%CI: 0.19, 0.58). After adjustment for sociodemographic and lifestyle variables, correlations between FFQ and DR for men and women were 0.57 (0.42, 0.69) and 0.41 (0.24, 0.55) (I) and 0.56 (0.44, 0.65) and 0.34 (0.20, 0.47) (II), respectively. Correlations between FFQs for men and women were 0.63 (0.49, 0.73) and 0.55 (0.41, 0.67) (I) and 0.66 (0.55, 0.74) and 0.63 (0.52, 0.72) (II). In conclusion, our study showed moderate FFQ validity and reproducibility for sugar intake evaluation.
