Association between air pollution-cold wave sequential events and ischaemic stroke incidence among elderly adults in Tianjin, China: a retrospective cohort study.

ABSTRACT:

Background

Both air pollution and temperature variability (with cold wave as an extreme form) may influence the incidence of ischaemic stroke (IS). This study aimed to examine the association between winter air pollution-cold wave sequential events (persistent air pollution followed by cold waves) and IS incidence among adults aged>=60 years.

Methods

Clinical data were sourced from the Tianjin Medical and Health Big Data Platform (covering 81 secondary/tertiary hospitals), and meteorological/air quality data were sourced from the National Meteorological Science Data Centre. Spearman rank correlation analysis was used to assess the relationships between meteorological variables (eg, 24-hour temperature decrease), atmospheric pollutants (including Air Quality Index (AQI)) and
