Long-term exposure to ambient NO₂ and adult mortality: A nationwide cohort study in China.

ABSTRACT:

Introduction

A number of population-based studies have investigated long-term effects of nitrogen dioxide (NO₂) on mortality, while great heterogeneities exist between studies. In highly populated countries in Asia, cohort evidence for NO₂-mortality association was extensively sparse.

Objectives

This study aimed to quantify longitudinal association of ambient NO₂ exposure with all-cause mortality in Chinese adults.

Methods

A national cohort of 30,843 adults were drawn from 25 provincial regions across mainland China, and followed up from 2010 through 2018. Participants' exposures to ambient air pollutants were assigned according to their residential counties at baseline, through deriving monthly estimates from high-quality gridded data
