Les Conditions Environnementales, les Inégalités Sociales et l'Instabilité Politique Accélèrent le Vieillissement: Environmental Conditions, Social Inequality, and Political Instability Accelerate Aging

This is the authors' abstract. We don't add key points for this paper.

A groundbreaking international study published in Nature Medicine today reveals that our environments—including pollution, social inequality, and weak democratic institutions—significantly accelerate how our lifespan ages. The research, involving 161,981 individuals across 40 countries, introduces a global exposome framework and shows that multiple exposures can predict bio-behavioral age gaps (BBAGs), a novel measure of accelerated aging. BBAGs are the difference between a person’s actual age and the age-predicted from their health, cognition, education, functionality, and risk factors like cardiometabolic health or sensory impairments
