Is this trial a fit for you?

Likely a good fit

Healthy children aged 6 to 10 years who are within the WHO growth percentiles and have assent plus parental consent.

Probably not a fit

Children with acute or chronic illnesses or those unable to comply with study procedures may not benefit from this research.

What this trial studies

The study aims to determine the dietary leucine requirement for healthy school-age children using the minimally invasive indicator amino acid oxidation (IAAO) protocol. It employs a randomized crossover design to estimate the minimum leucine intake needed for growth and metabolism, with 7 participants undergoing repeated measurements. Breath tests and urinary markers will be collected to assess amino acid metabolism under controlled dietary leucine intakes. The research is conducted at BC Children's Hospital Research Institute with oversight from the University of British Columbia. Results could refine pediatric leucine recommendations beyond adult-derived values.

Why it matters

Potential benefit: If successful, findings could lead to more accurate dietary guidelines for leucine in children, supporting healthy growth and development.

How similar studies have gone: Previous work in adults and limited pediatric data using IAAO supports the feasibility of this approach, though pediatric-specific leucine targets are not yet established.
