为寻找一种可靠的营养筛查工具，评价成都市女性居民营养状况与疾病的关系，对修订后的半定量食物频率问卷（SQFFQ）进行了信度和效度检验。通过比较SQFFQ与3天膳食回忆的“标准”方法来评估其效度，通过比较第一次SQFFQ与第二次SQFFQ在4周的间隔来评估其信度。相关性分析表明，在信度方面，22种营养素的平均相关系数（CC）为0.66，调整能量后降至0.60;组内相关系数（ICC）的平均值为0.65。就有效性而言，平均CC为0.35，在调整能量或营养素的CC后保持稳定。SQFFQ调查中17种营养素的效度与3天膳食回忆结果相关。结果表明，修订后的SQFFQ可用于调查营养素在成都市女性居民疾病发生中的作用。
ABSTRACT To find a credible nutritional screening tool for evaluating relationship between nutritional status and diseases in Chengdu female residents, the reliability and validity of a revised semi-quantitative food frequency questionnaire (SQFFQ) were tested. The validity was assessed by comparing the SQFFQ with the ‘standard’ method of 3 days’ dietary recall, and the reliability was assessed by comparing the first SQFFQ with the second SQFFQ at 4 weeks interval. Correlation analysis showed that, for reliability, the average correlation coefficient (CC) of 22 kinds of nutrients was 0.66 and reduced to 0.60 after adjusting for energy; the average of intra-class correlation coefficients (ICC) was 0.65. For validity, the average CC was 0.35 and remained stable after adjusting for CC of energy or nutrients. Validity of 17 nutrients in SQFFQ survey had correlation with result of 3 days’ dietary recall. The results showed that the revised SQFFQ can be used for investigating the role of nutrients in development of disease in Chengdu female residents.
