摘要: 目的 对即时性图像法应用于学龄前儿童膳食调查进行效果评价。方法 招募60位幼儿园儿童及其家长,为儿童提供食物原料经严格称重后烹制的午餐。进餐前家长从三个角度对食物进行拍摄,同样方法拍摄剩余食物,并将图像文件发送至固定邮箱,次日接受针对儿童的24 h膳食回顾调查,膳食估量小组成员对图片中的食物进行估重。得到称量数据、图像法数据和24 h回顾法数据,归类汇总三组数据并进行营养计算。结果 与24 h回顾法数据相比,除水果和带鱼外,图像法数据与称重数据的相关性更好。除畜禽肉类和带鱼外,图像法的数据与称重法更接近。基于图像法数据计算的能量与各营养素的摄入量数据,与称重数据的计算结果更接近。结论 与24 h回顾法相比,用即时性图像法膳食调查技术对学龄前儿童进行膳食调查,可获得与实际重量更接近的食物消费量数据。

Abstract: Objective To assess the usefulness and efficiency of a new method of dietary assessment with instant photography applied in preschool children's dietary survey.Methods Sixty preschool children and their parents were recruited with informed consent for a dietary assessment study.The preschool children were served with a meal at noon with foodstuff accurately weighed before cooking.The parents were asked to take photographs of all dietary items by the designed way in which three views of foods in different angle were recorded with a smart phone or a digital camera.The remainder foods were also photographically recorded after the meal.In next day,the parents were interviewed for food amount supplied to their children by investigators by a 24 h dietary recall.The digital files of dietary images were then transferred by internet to investigators.The works of the dietary recall,the image quantification and weighing method were operated by three different groups.Energy and nutrient intakes were calculated for each subject from the meal. Results Compared to the data from 24 h dietary recall,food amount data estimated by image quantification were more correlated with weighed data except fruits and beltfish.Also they were more close to weighed data and had smaller standard deviation except meat and beltfish.Values of energy and almost all the nutrients calculated based on food weight from image quantification were more close to those of weighed data compared to the 24 h dietary recall.Conclusion The method of dietary assessment with instant photography can be effectively used in preschool children's dietary survey and has more efficiency than conventional 24 h dietary recall.

Key words: dietary survey, methodology, dietary assessment with instant photography, 24 hour dietary recall, preschool children
