Hypothesis
Varying portion sizes in preschool meals will affect the total energy intake of children over a 24-hour period.
Conclusion
The variation in meal portion sizes at preschools did not lead to significant differences in the total 24-hour energy intake of the children.
Supporting Evidence
- Children's energy intake at preschool averaged 33% of the recommended energy allowance.
- Mean energy intake outside of preschool was 58% of the recommended energy allowance.
- Despite varying portion sizes, total 24-hour energy intake remained consistent across preschools.
Takeaway
This study looked at how different sizes of meals served to preschoolers affected how much they ate in a day. It found that even with different portion sizes, kids ate about the same amount overall.
Methodology
The study observed food items and portion sizes served at 16 preschools over 3 to 8 days and assessed children's energy intake at preschool and outside of preschool.
Potential Biases
Potential underreporting of energy intake by parents, particularly among African American children.
Limitations
Data on outside-of-school calorie intake relied on parent reporting, which may lead to underreporting.
Participant Demographics
Predominantly African American children aged 4.0 to 4.5 years, with all participants qualifying for Head Start programs.
