The exposome of healthy and accelerated aging across 40 countries

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 dif…

Egyptian researchers join global study linking pollution, poor governance to accelerated brain aging - Dailynewsegypt

A groundbreaking international study published in Nature Medicine reveals that exposure to environmental pollutants, social inequality, and weak democratic institutions can significantly accelerate brain aging and increase the risk of cognitive decline. The study, which analyzed data from 161,981 individuals across 40 countries, introduced a new concept called “Behavioral-Biological Age Gaps” (BBAGs)—the difference between chronological
