Long-term exposure to air pollution and gastrointestinal disease: findings from a nationwide cohort study in China.

ABSTRACT:

Background and aims

Air pollution poses significant risks to human health, but its impact on gastrointestinal (GI) health remains underexplored. This study assesses the long-term effects of air pollution on GI diseases using data from the China Health and Retirement Longitudinal Study (CHARLS).

Methods

This nationwide cohort study utilized CHARLS data from participants recruited in 2011, followed by surveys in 2013, 2015, 2018, and 2020. Long-term exposure to PM_2.5, PM₁₀, SO₂, NO₂, CO, and O₃ was assessed using geocoded residential addresses linked to air quality data. Cox proportional hazards models and subgroup interaction analyses were used to evaluate associations between pollutants and GI disease incidence, adjustin
