Acute effects of air pollution on ischaemic stroke onset and deaths: a time-series study in Changzhou, China.

ABSTRACT:

Objective

To investigate the acute effect of air pollutants on ischaemic stroke (IS) and IS-related death.

Setting

Five urban districts in Changzhou, China, between 9 January 2015 and 31 December 2016.

Participants

A total of 32 840 IS cases and 4028 IS deaths were enrolled.

Main outcome measures

A time-series design, generalised additive model and multivariable regression model were used to examine the percentage change (95% CI) in daily IS counts and deaths with an IQR increase in air pollutant levels for different single or multiple lag days in single-pollutant and two-pollutant models.

Results

Daily IS counts increased 0.208% (95% CI 0.036% to 0.381%) with an IQR increment in the levels of nitrogen dioxide (NO₂). The estimated risk of NO
