Increasing Lean Protein Intake in Preschool-age Children and Assessing Effects on Cognition and Select Health Outcomes

Sibylle Kranz, PhD, RDN20 enrolled

Overview

The proposed project addresses the goal of exploring preschooler's ability to recognize changes in feelings of hunger/satiety based on consuming a snack and a meal (lunch/dinner) that are either based on the usual childcare center fare (control) or are based on lean meats (intervention), which will have a lower glycemic index.

Outcomes

Primary Outcomes

Glycemic load of diet

Estimated intake of glycemic load of meals and snacks consumed. Plate-waste method will be used to calculate total energy, GI, GL consumed at each meal and snack using disaggregated intake (in grams) and analysis using Nutrient Data System for Research (NDS-R) software.

Time frame: 6 study days

Hunger/Satiety self-reported on 4-point scale

Self-reported feelings of hunger or fullness using: 1 = Very hungry, 2 = A little hungry, 3 = A little full, 4 = Very full

Time frame: 6 study days

Secondary Outcomes

Blood pressure

Measured blood pressure 60 minutes after the meal.

Time frame: 60 minutes after the meal.

Blood glucose

Blood glucose concentration 60 minutes after the meal. Measured using finger-stick and glucometer reading.

Time frame: 6 study days

Executive function: focus and short-term memory

Using the "track-it" game, children respond to visual cues.

Time frame: 6 study days

Executive function: memory and focus

Using KRISP, children respond to visual cues to assess focus and short-term memory

Time frame: 6 study days

Executive Function: Focus and Concentration

Using the "peg it" game, children are asked to use a small wooden hammer to tab the table surface. First, they repeat how many tabs the researcher demonstrated (1 or 2), then they are asked to tab the opposite, so if the researcher tabs once, they tab twice and when the researcher tabs twice, they tab once.
