Time for Lunch: The Impact of Lunch Time Constraints on Child Eating Behaviors
A study testing Lunch period length in people with Time Constraints During School Meals, run by University of Illinois at Urbana-Champaign at 1 site in United States.
Trial summary
Recent peer-reviewed observational evidence suggests that school children receive anywhere from 10-33 minutes of seated lunch time and that students with less time to eat discard higher amounts of milk, entrée (i.e. protein items), grains, and vegetables. Read more about this study

About this study
Recent peer-reviewed observational evidence suggests that school children receive anywhere from 10-33 minutes of seated lunch time and that students with less time to eat discard higher amounts of milk, entrée (i.e. protein items), grains, and vegetables. This waste is a missed nutritional and food security opportunity and also negatively impacts the environment. The purpose of this study is to estimate the impact that lunch time constraints have on child food selection, consumption and waste behaviors using a crossover trial design, where the duration of seated lunch times are randomly allocated to be either 10 minutes or 20 minutes each day.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lunch period lengthBehavioural
We are randomly allocating a 10 minute or 20 period of seated lunch time.
| Study group | Role | What they receive |
|---|---|---|
| Shortened lunch period | Experimental | The amount of seated lunch time will be 10 minutes. Receives: Behavioral: Lunch period length |
| Longer lunch period | Experimental | The amount of seated lunch time will be 20 minutes. Receives: Behavioral: Lunch period length |
What is being measured
The primary outcome is the main question the study is designed to answer.
Food item selection
The type and number of school meal components selected by students to eat for lunch.
Measured: Ranges from 5 days to 20 days, depending upon how long each participant elects to enroll in the summer camp
Food item consumption
The weight of each school meal component that was consumed by each child during lunch. Each measured in grams.
Measured: Ranges from 5 days to 20 days, depending upon how long each participant elects to enroll in the summer camp
Food item waste
The weight of each school meal component that was discarded by each child during lunch. Each measured in grams.
Measured: Ranges from 5 days to 20 days, depending upon how long each participant elects to enroll in the summer camp
