本文研究了云锡矿工肺癌高危人群普查中所使用的食物频率问卷（FoodFrequencyQuestionnaire，FFQ）的信度和效度。信度研究是将间隔一年的食物频率问卷资料相比较做相关分析（95FFQvs．94FFQ）；效度研究是以1995年四季28天24小时饮食回顾调查资料（24H—R）为标准，将食物频率问卷资料调查结果与其比较做相关分析（95FFQVS．24H—R）。以一致率来评价膳食调查工具的可靠程度。研究结果表明：用该食物频率问卷对单一食物摄人频率进行调查时，其信度和效度一致性均不到60％；而对营养素摄人量进行调查时，其信度和效度一致性可分别达到70％和87％。提示该食物频率问卷用于营养素与疾病关系的研究较为适宜，而用于食物与疾病关系研究时应持慎重态度。
In this paper, the reliability and validity of the food frequency questionnaire (Food Frequency Questionnaire, FFQ) used in the census of high-risk groups of lung cancer in Yunnan Tin miners were studied. The reliability of the study is to compare food frequency questionnaire data at intervals of one year (95FFQvs. 94FFQ). The validity study is based on the 24-hour food recall survey data (24H-R) Frequency questionnaire data survey results do comparative analysis (95FFQVS.24H-R). Consensus rates are used to evaluate the reliability of dietary survey tools. The results of the research show that the reliability and validity consistency of the single food intake is less than 60% when using this food frequency questionnaire, while the reliability and validity of the nutrient intake survey are consistent Sex can reach 70% and 87% respectively. It is suggested that the food frequency questionnaire is more suitable for the study of the relationship between nutrients and disease, and should be used with caution in the research of the relationship between food and disease.
