This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The epidemic of overweight among children underscores the need to identify contributing environmental factors. marketplace trends for excessive and growing protion sizes have reinforced concerns that large portions may directly contribute to this problem by promoting excessive intake. Empirical investigation of portion size effects on children's eating are limited. Two studies have demonstrated effects of large portions to stimulate energy intake at meals. The scope and nature of such effects, however, remains unclear. The proposed research involves a series of four portion size experiments to be conducted with pre-school aged children. The first three experiments will evaluate the scope of portion size effects by determining: the effect of portion size on children's consumption of sweetened beverages, the effect of portion size on children's fruit and vegetable (FV) intake, and the combined effects of portion size and energy density on children's energy consumption. In an effort to address mechanism, the fourth experiment will evauate the effects of portion size and plate size on eating duration, bite size, and bite frequency. The results of this basic behavioral investigation may be used to infrom the design of long-term studies on the effects of protion size on children's energy consumption and weight. Further, these basic research findings may also be used to develop interventions aimed at modifying potentially obesigenic aspects of young children's environments.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子弹和调查员（PI）可能已经从其他NIH来源获得了主要资金，因此可以在其他清晰的条目中代表。列出的机构适用于该中心，这不一定是调查员的机构。儿童超重的流行强调了确定促成环境因素的必要性。过度和不断增长的产品大小的市场趋势引起了人们的担忧，即大部分可能通过促进过度摄入而直接促成这一问题。对儿童饮食的部分尺寸影响的实证研究有限。两项研究表明，大部分刺激进餐时能量摄入的影响。但是，这种影响的范围和性质尚不清楚。拟议的研究涉及一系列四部分大小实验，将与学龄前儿童进行。前三个实验将通过确定：部分大小对儿童食用甜味饮料的影响，部分大小对儿童水果和蔬菜（FV）摄入的影响以及部分大小和能量密度对儿童能量消耗的份量综合作用。为了解决机制，第四个实验将避免部分大小和板尺寸对饮食持续时间，咬合尺寸和咬合频率的影响。这项基本行为研究的结果可用于基础有关针对儿童能耗和体重的影响的长期研究的设计。此外，这些基础研究发现也可用于制定旨在修改幼儿环境潜在的青春期方面的干预措施。
