Overview
- Nature Aging published the peer-reviewed analysis of 86,149 adults across 27 European countries using AI-derived biobehavioral age gaps.
- Multilingual participants were 2.17 times less likely to show accelerated aging, whereas monolinguals were roughly twice as likely to display early aging patterns.
- Protective associations appeared in both cross-sectional assessments and longitudinal tracking over time.
- Effects remained significant after adjusting for linguistic, social, physical and sociopolitical factors, strengthening confidence in the association without proving cause and effect.
- The study reports greater protection with each additional language and calls for longitudinal and intervention trials, while noting potential public-health value in promoting language learning.
