摘要
目的比较3天24小时膳食回顾法和食物频率法在评估人群脂肪摄入的差异及相关性,为膳食脂肪研究提供依据。方法对从浙江省抽取的511名调查对象同时采用3天24 h膳食回顾法和食物频率法进行膳食调查,分别计算脂肪、脂肪酸和能量等的每日摄入量及脂肪供能比,并对结果进行统计分析。结果两种方法计算得到的能量、脂肪及脂肪供能比结果差异无统计学意义;两种方法评估能量、脂肪、脂肪供能比的相关系数分别为0.51、0.58和0.57,同一调查对象在这两种方法中被分到相同或相邻组的比率:能量为80.73%,脂肪为84.80%,脂肪供能比为83.38%。结论在进行膳食脂肪与疾病关系研究时可采用本文中的食物频率法代替3天24小时回顾法来评估人群脂肪摄入情况。
Objective To compare the difference and correlation of dietary fat intakes measures from the food-frequency questionnaire（ FFQ） with measures from 24 hour dietary recalls（ 24HDRs）,and provide evidence for the future research of dietary fat. Methods A total of 511 participants,selected from Zhejiang province,were asked to complete an FFQ and 24 HDRs. The consumption of energy,fat,fatty acids,the percentages of energy from fat were calculated with the FFQ and 24 HDRs and the results were analyzed. Results There was no difference between FFQ and 24 HDRs in energy,fat,fatty acids and the percentages of energy from fat. Sperman＇s rank correlation coefficient between the two methods were 0. 51 in energy,0. 58 in fat and 0. 57 in the percentages of energy from fat.The proportion of subjects who were assigned to the same or adjacent quintile groups were80. 73% for energy,84. 81% for fat and 83. 38% for the percentages of energy from fat.Conclusion An effective FFQ can evaluate dietary fat consumption and rank participants well. Selecting the simple and easy FFQ method to assess the dietary fat intake would be a good choice when research the relationship between dietary fat and chronic disease in the future.
