【 摘 要 】

To find a credible nutritional screening tool for evaluating relationship between nutritional status and diseasesin Chengdu female residents, the reliability and validity of a revised semi-quantitative food frequencyquestionnaire (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 thesecond SQFFQ at 4 weeks interval. Correlation analysis showed that, for reliability, the average correlationcoefficient (CC) of 22 kinds of nutrients was 0.66 and reduced to 0.60 after adjusting for energy; the averageof intra-class correlation coefficients (ICC) was 0.65. For validity, the average CC was 0.35 and remainedstable after adjusting for CC of energy or nutrients. Validity of 17 nutrients in SQFFQ survey had correlationwith result of 3 days’ dietary recall. The results showed that the revised SQFFQ can be used for investigatingthe role of nutrients in development of disease in Chengdu female residents.
