孕早期食物频率法与三天24小时膳食回顾法的比较
Comparison of Food Frequency Questionnaire in Early Pregnancy with 3 days 24-Hour Recall
摘要
Abstract
[Objective]To evaluate the validity of a food frequency questionnaire (FFQ) designed to assess nutrient intake of pregnant women and other common population.[Method]A total of 111 pregnant women who completed the FFQ and 3 days 24-hour recall(3days 24HR) during 10 to 13 week were included in our study. Wilcoxon Rank-Sum Test and Bland-Altman method were uesd to compare the dif-ference of intake between FFQ and 3 days 24-hour recall. Consistency was measured by Spearman's rank correlation.[Result]In general,mean intake of energy,cereals and vegetables was consistant when assessed with FFQ compared with 3 days 24-hour recall. For energy and three macronutrients,the Spearman correlation coefficients between the two assessment tools ranged from 0.249(fat)-0.529(protein). The Spearman correlation coefficients ranged from 0.180(grains)-0.578(milk and milk products) in different food groups,with the exception of cereals,tuber,phytocomycetes and fruits. Bland-Altman plots revealed significant relationships between the ratios and the average of the two methods,and the ratios of energy,protein and fat were around 1.[Conclusion]This FFQ is a reasonably valid tool for assessing most food and nutrient intakes of pregnant women and and other common population.关键词
