Association between long-term exposure to PM_2.5 chemical components and metabolic syndrome in middle-aged and older adults.

ABSTRACT:

Background

Previous studies indicated that exposure to ambient fine particulate matter (PM_2.5) could increase the risk of metabolic syndrome (MetS). However, the specific impact of PM_2.5 chemical components remains uncertain.

Methods

A national cross-sectional study of 12,846 Chinese middle-aged and older adults was conducted. Satellite-based spatiotemporal models were employed to determine the 3-year average PM_2.5 components exposure, including sulfates (SO₄ ^2-), nitrates (NO₃ ^-), ammonia (NH₄ ⁺), black carbon (BC), and organic matter (OM). Generalized linear models were used to investigate the associations of PM_2.5 components with MetS and the components of MetS, a
