The exposome of healthy and accelerated aging across 40 countries.

ABSTRACT: Protective and risk factors can drive healthy or accelerated aging, with distinct environments modulating their effects. The impact of the exposome-the combined physical and social exposures experienced throughout life-on accelerated aging remains unknown. We assessed delayed and accelerated aging in 161,981 participants from 40 countries (45.09% female; mean age, 67.06; s.d., 9.85) by measuring biobehavioral age gaps (BBAGs), defined as the difference between estimated age from protective and risk factors and chronological age, in cross-sectional and longitudinal designs. BBAGs predicted chronological age, followed by regional and exposomal factor analyses, linked to accelerated aging. Europe led in healthy aging, while Egypt and South Africa showed the greatest acceleration; Asia and Lat
