This study describes the development and reproducibility of a 128-item quantitative food frequency questionnaire (FFQ) to measure usual food consumption for women in southeast China. The FFQ was pre-tested using 51 Chinese women who recently migrated to Australia. Cronbach's alpha coefficient was 0.81 for internal consistency. The reliability of the FFQ was then assessed by another test-retest study. A sample of 41 women residing in southeast China was interviewed twice within 12 weeks. Intraclass correlation coefficients were moderate to high for mean food group consumption (0.43-0.96) and mean daily nutrient intakes (0.47-0.89). Kappa statistics for eating habits ranged from 0.27 to 0.89 in the test-retest. The mean ratio of energy intake to basal metabolic rate was 1.73 (S.D. 0.39) in both test and retest samples. The study confirmed that the FFQ method using standard containers is appropriate to assess dietary intake for women in southeast China.
本研究描述了一份包含128个条目的定量食物频率问卷（FFQ）的编制过程及其可重复性，该问卷用于测量中国东南部女性的日常食物摄入量。该FFQ在51名近期移民到澳大利亚的中国女性中进行了预测试。内部一致性的Cronbach'sα系数为0.81。然后通过另一项重测研究评估了FFQ的可靠性。对41名居住在中国东南部的女性样本在12周内进行了两次访谈。食物组平均摄入量（0.43 - 0.96）和每日营养素平均摄入量（0.47 - 0.89）的组内相关系数为中度到高度。重测中饮食习惯的Kappa统计量在0.27至0.89之间。测试样本和重测样本中能量摄入与基础代谢率的平均比值均为1.73（标准差0.39）。该研究证实，使用标准容器的FFQ方法适用于评估中国东南部女性的饮食摄入量。
