Measuring Energy Use in Infants

This study aims to understand how infants use energy during their first three months of life. Researchers will measure energy expenditure (how many calories an infant burns) using a special infant metabolic chamber and a method called doubly labeled water. This will help them learn more about infant development and overnutrition. They want to see how accurate these measurements are and how they can be adjusted for different infant sizes. The study is looking for 70 healthy, full-term infants between 1 and 3 months old who are exclusively fed breast milk or formula. The current recruitment status is unclear.

Study design
This is an observational study, meaning researchers will observe participants without giving any interventions. It plans to enroll 70 infants.
What's involved
You would need to complete 3 clinic visits within about 14 days at Pennington Biomedical Research Center. Your infant would also need to be willing to accept doubly-labeled water.
Compensation
Not stated in the trial record.
Follow-up
Energy expenditure will be measured at approximately 1 week, and again about one week later.

What this trial measures

  • Energy Expenditure by infant metabolic chamberApproximately 1 week

    Energy expenditure by infant metabolic chamber measured twice about 1 week apart for test re-test reliability in infants aged 1-3 months.

  • Energy expenditure by doubly labeled waterApproximately 1 week

    Energy expenditure by doubly labeled water measured over approximately 7 days in infants aged 1-3 months
