Impact of childhood exposure to traffic related air pollution on adult cardiometabolic health: Exploring the role of perceived stress.

Background: Little is known about how childhood exposure to traffic-related air pollution (TRAP) and stress interact to affect adults' cardiometabolic health. We examined this interaction and assessed the impact of over 10 years of childhood TRAP exposure on cardiometabolic health.

Methods: From 2018 to 2023, 313 young adults from the Southern California Children's Health Study were enrolled in a follow-up assessment.
