The levels of PM 2.5, PM 10, SO 2, and NO 2 were significantly related to the number of admissions for RA-ILD.

In the 5-year study, there were 221 hospitalizations for RA-ILD in Jinan city. This time-series study was performed from January 1 st, 2015 to December 31 st, 2019.

The relationships between ambient air pollutant concentrations, including PM 2.5, PM 10, sulfur dioxide (SO 2), ozone (O 3), and nitrogen dioxide (NO 2), and monthly hospitalizations for RA-ILD were studied by employing a general linear model with a Poisson distribution.

Our research aimed to explore whether there is a correlation and to estimate how the association was distributed across various lags in Jinan, China. Little is known within the medical community about the impact of air pollution on hospital admissions due to rheumatoid arthritis associated with interstitial lung disease (RA-ILD).
