To our knowledge, a direct observation protocol for assessing dietary intake among young children in child care has not been published. This article reviews the development and testing of a diet observation system for child care facilities that occurred during a larger intervention trial. Development of this system was divided into five phases, done in conjunction with a larger intervention study; (a) protocol development, (b) training of field staff, (c) certification of field staff in a laboratory setting, (d) implementation in a child-care setting, and (e) certification of field staff in a child-care setting. During the certification phases, methods were used to assess the accuracy and reliability of all observers at estimating types and amounts of food and beverages commonly served in child care. Tests of agreement show strong agreement among five observers, as well as strong accuracy between the observers and 20 measured portions of foods and beverages with a mean intraclass correlation coefficient value of 0.99. This structured observation system shows promise as a valid and reliable approach for assessing dietary intake of children in child care and makes a valuable contribution to the growing body of literature on the dietary assessment of young children.
据我们所知，尚未发表过用于评估托育机构幼儿饮食摄入量的直接观察方案。本文回顾了在一项更大规模干预试验期间，针对托育机构开发和测试饮食观察系统的情况。该系统的开发分为五个阶段，与一项更大规模的干预研究同时进行；（a）方案制定，（b）现场工作人员培训，（c）在实验室环境中对现场工作人员进行认证，（d）在托育机构实施，以及（e）在托育机构环境中对现场工作人员进行认证。在认证阶段，采用了多种方法来评估所有观察者在估计托育机构常见食物和饮料的种类及数量方面的准确性和可靠性。一致性检验表明，五名观察者之间具有高度一致性，并且观察者与20份经测量的食物和饮料之间具有高度准确性，组内相关系数均值为0.99。这种结构化观察系统有望成为评估托育机构儿童饮食摄入量的一种有效且可靠的方法，并为关于幼儿饮食评估的不断增长的文献做出了宝贵贡献。
