Status Recruiting

Clinical Trial Summary

This prospective random controlled cross-over intervention studies is designed to ascertain if children feel different levels of hunger and fullness before and after eating test meals consisting of high-satiety vs. usual foods and if the child's perceived hunger/fullness is related to their salivary ghrelin levels and a variety of learning outcomes. Data are collected at the Diet and Nutrition (DAN) laboratory on repeated study days (8am - 4 pm).

Clinical Trial Description

The investigator's previous research has shown that preschoolers recognized changes in the feelings of hunger/fullness before and after a single test meal. If preschooler's feelings of hunger are associated with their ghrelin (hunger hormone) levels is not known. This study is designed to assess children's changes in feelings of hunger throughout the day (8 pm to 4 pm) and to measure both subjective feelings of hunger and salivary ghrelin levels before and after a standardized test meal (lunch). An important secondary outcome related to children's feelings of hunger is their ability to learn. Currently, there is lack of data on the direct link between perceived hunger/fullness and learning processes. This study addresses these gaps using preschooler's perceived feelings of hunger and fullness (using a published 4-point scale (Kranz S.et al. "High-Protein and High-Dietary-Fiber Breakfasts Result in Equal Feelings of Fullness and Better Diet Quality in Low-Income Preschoolers Compared with Their Usual Breakfast" J Nutr doi: 10.3945/jn.116.234153, 2017) and a battery of learning tests (HTKS, KRISP, Stroop-style tasks, Woodcock Johnson vocabulary test, DCCS, and curisoty measures.) ;
