不同膳食调查方法评估人群能量和营养素摄入量的比较

目的比较称重法、回顾法和食物频率法在评估人群能量和营养素摄入的差异性和相关性。方法2002年中国居民营养与健康调查中同时使用称重法、回顾法和食物频率法进行膳食调查的15～75岁居民23198名(男性11107,女性12091),利用称重法和食物频率法的结果对回顾法进行修正。结果与称重法相比,回顾法低估能量、脂肪、脂肪供能比、维生素E以及大部分矿物质的摄入,频率法低估脂肪、蛋白质供能比、脂肪供能比、维生素E和钠的摄入,称重法修正回顾法和频率法修正回顾法与称重法的相关系数,以及高估和低估人群方面都没有明显的差别。结论以称重法为标准的验证结果表明,称重法修正回顾法和频率法修正回顾法在调查能量和营养素摄入时与称重法的相关性均较好,后者可以代替前者。

Comparative Study on the Results of Energy and Nutrients Intakes Investigated by Different Evaluation Methods

Objective To compare the difference and correlation of energy and nutrients intakes investigated by Food Weighted Record,24 Hours Recall and Food Frequency Questionnaire(FFQ)methods.Subjects 23 198 subjects(male 11 107,female 12 091)finished all three food intake investigations among the 2002 National Nutrition and Health Survey.The data collected by 24 Hours Recall was adjusted by the data of condiment investigated by Food Weight Record and Food Frequency Questionnaire.Results Compared to results of Food Weighted Record method,energy,fat,fat energizes compares,vitamin E,and most minerals were underestimated by 24 hours recall method;and fat,ratios of protein-borne and fat-borne energy,vitamin E and Na were underestimated by Food Frequency Questionnaire.There are no significant differences for correlation coefficient between result of Food Weight Record and results of 24 Hours Recall methods respectively revised by Food Weight Record and by Food Frequency Questionnaire.Conclusion Based on the comparison with Food Weighted Record method,the energy and nutrients intakes might be investigated accurately by either of the Food Weighted Record revised 24 Hours Recall and the Food Frequency Questionnaire revised 24 Hours Recall,the former one can be replaced by the later ones.
