Stanford-Led Study of 322 People Links Living Location to Biological Aging

A Cell study of 322 healthy people across Europe, East Asia and South Asia found that geography can shift biological age, with East Asians living outside Asia appearing older while Europeans outside Europe appeared younger.
Using deep multiomics profiling, the Stanford-led team separated ancestry from environment by comparing people with the same genetic background living on different continents.
Genetic ancestry still left strong signatures in immunity, metabolism and gut bacteria: South Asian volunteers showed higher pathogen exposure markers, while Europeans had richer gut microbial diversity and higher chemicals tied to heart-disease risk.
The researchers also identified a new link among a telomerase gene, a gut microbe and the lipid sphingomyelin, suggesting one pathway through which microbes may influence cellular aging.
The open-access dataset is intended to support precision medicine tailored to both ancestry and environment rather than one-size-fits-all diagnostics and treatment.

Stanford 2026 Global Study: Genetic Ancestry and Geography Profoundly Influence Biological Age and Molecular Health
Overview
A major global study led by Stanford School of Medicine, published in May 2026, profiled 322 people across three continents to explore how genetic ancestry and geographic location shape biological age. The research found that certain molecular profiles are closely linked to a person’s ethnic background, and these patterns remain even when individuals move to new locations. For example, people of South Asian descent showed higher markers of pathogen exposure, suggesting a genetic influence on immune responses. These findings provide important insights for researchers and clinicians working to understand and address health disparities around the world.
