背景食物照片和标准份量已经被用于成人，以评估记录饮食摄入量时的份量。这些方法的有效性可能会降低时，记忆/回忆是必需的，儿童可能会有问题，使用这些techniques.Methods成人（47）和儿童（37）被招募的大学人员，他们的孩子和孩子的朋友，以评估部分大小的9个自助服务量的选定的食物项目，使用食品照片和标准描述的部分大小。部分大小估计后直接自我serving和3 -4 days.Results实质性的差异，在估计的部分大小观察到大多数食物，无论使用的方法或年龄的主题，中位数差异范围：-52-100%。对于儿童有更大的错误使用这两种方法比成人。两种估计体重的方法之间存在显着差异。食物图谱为大多数食物项目提供了较高的估计重量中位数。有很少的差异，估计的部分大小之间的两个测试periods.Conclusion的研究结果表明，无论是替代方法或修改的方法，在这里使用的估计部分大小在年轻的科目，例如标准的食物部分大小为不同年龄的儿童，如那些正在开发的食品标准局，将是更合适的。
Background Food Photographs and standard portion sizes have been used with adults to assess portion size when recording dietary intake. The effectiveness of these methods may be reduced when memory/recall is required and children may have problems using these techniques.Methods Adults (47) and children (37) were recruited from amongst university personnel, their children and children's friends to assess portion sizes of nine self-served amounts of selected food items using food photographs and standard descriptions of portion sizes. Portion sizes were estimated directly after self-serving and three-4 days later.Results Substantial differences in the estimate of portion sizes were observed for most foods regardless of the method used or the age of the subjects, median difference range: -52-100%. For children there were greater errors using both methods than for adults. Significant differences were found between the two methods of estimating weight. The food atlas provided higher median estimated weights for the majority of the food items. There were very few differences in the estimation of portion sizes between the two testing periods.Conclusion The findings would suggest that either an alternative method or a modification of the methods used here for estimating portion sizes in young subjects, for example standard food portion sizes for children of different ages such as those that are being developed by the Food Standards Agency, would be more appropriate.
