How early experiences and parent sensitivity affect infant cellular aging

The impact of stress and caregiver sensitivity on infant cellular aging in a population of under-resourced families: A randomized controlled trial.

['FUNDING_R01'] · UNIVERSITY OF WASHINGTON · NIH-11362274

This project will see if a home-visiting program that boosts caregiver sensitivity can protect infants under one year from early cellular aging.

What this research studies

If you join, you and your baby would be randomly assigned to receive Promoting First Relationships® home visits or usual care. Trained providers will coach parents to be more responsive and collect small biological samples from infants to measure telomere length and epigenetic age. The team plans to enroll about 250 families through WakeMed pediatric clinics and follow infants during their first year. The goal is to learn whether strengthening parent–infant interactions can reduce early biological signs of aging.

Who could benefit from this research

Good fit: Parents or primary caregivers of infants under 12 months receiving pediatric care at WakeMed, especially families from under-resourced backgrounds, are the intended participants.

Not a fit: Infants older than one year, families who do not receive the home-visiting intervention, or those living outside the WakeMed service area would not directly receive the program benefits.

Why it matters

Potential benefit: If successful, this could show that parent-support home visits slow cellular aging in infants and potentially reduce risk for later health problems.

How similar studies have performed: Previous home-visiting programs have improved parent sensitivity and child outcomes, but few randomized trials have measured effects on infant telomere length or epigenetic aging, so this application is relatively novel.
