Ambient long-term air pollution exposure and epigenetic aging clocks: A systematic review and meta-analysis.
Abstract
Ambient air pollution may accelerate biological aging, but the extent of its impact remains uncertain. Epigenetic clocks capture aging by comparing biological to chronological age, highlighting whether an individual is aging biologically faster (accelerating) or slower (decelerating) than expected. This systematic review and meta-analysis aimed to evaluate the association between long-term outdoor air pollution exposure [particulate matter (PM

Research summary
The paper claims that long-term exposure to ambient air pollution is associated with accelerated biological aging as measured by epigenetic clocks. This research is relevant as it explores environmental factors that may influence the biological aging process, contributing to our understanding of aging mechanisms.
