To determine the relative validity of a quantitative FFQ in assessing dietary fluoride intakes using 3 d food and beverage diaries for reference.
Parents were asked to complete questionnaires for the preceding week and diaries for 3 d for their children. Fluoride intakes were estimated from 'selected' foods and beverages for questionnaires and from 'all foods and beverages' for diaries. Data collected at 6, 9, 12, 16, 20, 24, 36, 48 and 60 months were analysed cross-sectionally.
A 3 d food and beverage diary and an FFQ collected through mail from children living in the state of Iowa.
Children from the Iowa Fluoride Study whose parents completed both an FFQ and a 3 d food and beverage diary at each analysed time point.
Correlations between daily mean dietary fluoride intake estimated from questionnaires and diaries range from 0·90 to 0·65.
A quantitative FFQ can provide relative estimates of dietary fluoride intake.
通过参考 3 天食物和饮料日记,确定定量 FFQ 评估饮食氟摄入量的相对有效性。
要求父母为其孩子填写前一周的问卷和 3 天的日记。从问卷中的“选定”食物和饮料以及日记中的“所有食物和饮料”来估算氟摄入量。在 6、9、12、16、20、24、36、48 和 60 个月收集的数据进行了横断面分析。
爱荷华州的儿童通过邮件收集的 3 天食物和饮料日记和 FFQ。
爱荷华州氟化物研究中的儿童,其父母在每个分析时间点都完成了 FFQ 和 3 天食物和饮料日记。
从问卷和日记中估算的每日平均饮食氟摄入量之间的相关性在 0.90 到 0.65 之间。
定量 FFQ 可以提供饮食氟摄入量的相对估计值。
