Examining brown fat and energy use in newborns

Official title: An Examination of Brown Adipose Tissue and Energy Expenditure in Infants

Run by Pennington Biomedical Research Center · NCT05517967 · Data updated 2026-11-12

This study looks at how brown fat develops in newborns and how it affects their energy use, to see if certain factors can help reduce the risk of obesity later on.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are infants aged 0 to less than 3 weeks who can safely undergo MRI procedures.

Probably not a fit

Patients who were born with health conditions that make the study procedures unsafe will not benefit from this study.

What this trial studies

This observational study investigates the development of brown adipose tissue in infants and its impact on energy expenditure. It aims to identify maternal and neonatal factors that influence the growth of brown fat and to measure how this tissue responds to mild cold exposure. The study will involve up to 60 infants aged 0-3 weeks, utilizing advanced techniques to assess body composition and metabolic rates under different temperature conditions. By understanding these factors, the research seeks to shed light on the origins of obesity risk starting from infancy.

Why it matters

Potential benefit: If successful, this study could provide insights into early interventions for obesity prevention in infants.

How similar studies have gone: While the specific approach of this study is novel, previous research has indicated the importance of brown adipose tissue in metabolic health.
