摘要
目的评价新研制的食物图谱辅助提高24h回顾法膳食调查准确性的效力。方法选取我院40名普食住院病人,分别用称重法、无图谱辅助的24 h膳食回顾法和有图谱辅助的24 h膳食回顾法对其进行一日膳食调查。将两种24 h膳食回顾法获得的食物消费量和营养素摄入量,与称重法获得的相应数据进行比较,计算与称重法的差值及其比例,比较两种24 h膳食回顾法所获数据与称重法的接近程度,探讨新研制的食物图谱在24 h膳食回顾中的作用。结果与称重法相比,无图谱辅助的24 h回顾法除鸡蛋和牛肉外,其余食物及所有营养素都是低估的,除脂肪、总维生素E、钠、钙和膳食纤维摄入量数据与称重法呈一定程度的正相关,其他营养素和各种食物摄入量则未见相关性。有图谱辅助的24 h膳食回顾所获食物和营养素摄入量与称重法无差别,且两组数据高度相关。结论新研制的食物图谱能有效提高24 h膳食回顾的准确性,携带方便,应用简便,是一种很好的现场调查工具,值得推广应用。[营养学报,2012,34(6):558-562]
Objective To evaluate the effectiveness of the newly developed food pictures in improving the accuracy of 24 h dietary recall survey.Method Forty inpatients were selected to study the accuracy of recall method in dietary survey with or without illustrative food pictares as compared with the weighing method.The data of food consumption and nutrients intakes were collected for comparison.Results Compared with weighing method,besides egg and beef,all the foods and nutrients were underestimated by 24 h dietary recall method without pictures.The data of fat,vitamin E,sodium,calcium and dietary fiber intakes showed certain degree of positive correlation with those obtained by weighing method,but not correlated in other nutrients and food intakes.The data of foods and nutrients intakes obtained by pictures-assisted 24 h dietary recall method were highly correlated with those obtained by weighing method.Conclusion The newly developed food pictures can improve the accuracy of 24 h dietary recall method.It is easy to carry and use,especially in field work and deserves wider application.[ACTA NUTRIMENTA SINICA,2012,34（6）：558-562]
