Accelerated aging as a mediator of the association between co-exposure to multiple air pollutants and risk of chronic kidney disease

Background: The association between co-exposure to multiple air pollutants and the occurrence of chronic kidney disease (CKD) was not well-established, and the mediating role of accelerated aging in this association remained uncertain. Methods: Using a cohort of 313,908 participants without CKD at b...

description Background: The association between co-exposure to multiple air pollutants and the occurrence of chronic kidney disease (CKD) was not well-established, and the mediating role of accelerated aging in this association remained uncertain. Methods: Using a cohort of 313,908 participants without CKD at baseline from the UK Biobank, we examined the potential association between co-exposure to multiple air pollutants, including PM2.5, PM10, PM2.5–10, NO2 and NOx, and the incidence of CKD by calculating an air pollution score. Mediation analyses were performed to examine the mediating role of accelerated aging (PhenoAgeAccel or KDM-BioAgeAccel) in this association. Results: During the median follow-up time of 12.9 years, 11,117 participants developed CKD. The results showed that per interquartile range (IQR) increment in air pollution score led to an approximately 9.0 % (6.6–11.4 %) elevated risk of occurring CKD. Compared to the first quartile (Q1) of air pollution score, those in the highest quartile (Q4) had a 21.2 % (14.8–27.9 %) higher risk of developing CKD (Ptrend<0.001). Mediation analyses suggested that PhenoAgeAccel and KDM-BioAgeAccel significantly mediated 1.5 % and 5.7 % of the association between air pollution score and incident CKD, respectively. Conclusion: Co-exposure to multiple air pollutants could increase the risk of developing CKD, with accelerated aging serving as a partial mechanism in the relationship between air pollution and CKD. These findings highlight the importance of reducing air pollution, and suggest a possible mechanism from air pollution to CKD through accelerated aging.
