INTRODUCTION: Limited evidence exists on the links between ambient air pollution and fractures. This study aimed to investigate the association between short-term exposure to criteria air pollutants and hospital admissions for fractures.
METHODS: We collected daily data on six criteria air pollutants and fracture admissions from Beijing Jishuitan Hospital between June 2021 and May 2023. Generalized additive models (GAM) with quasi-Poisson regression were applied to quantify the effects of air pollutants on admissions.
RESULTS: We identified 16,532 records on fracture admissions. At the lag03 day, an increase of 1 μg/m3 in PM2.5 and NO₂ was significantly associated with a 0.12% (95% CI: 0.01, 0.23%) and 0.26% (95% CI: 0.01, 0.51%) increase in fracture admissions, respectively. The exposure-response curve for PM2.5 showed a sharp rise after an initial decline at lower concentrations, which may be a model artifact. Stratified analyses revealed stronger associations in the younger population and a significant association between PM2.5 exposure and fracture risk in males. PM2.5 was also significantly associated with admissions for fragility fractures.
DISCUSSION: This study suggests that short-term exposure to air pollution, with observed cumulative lag effects, may increase the risk of fracture-related hospitalizations. These findings highlight the potential role of air pollutants as an environmental risk factor for fractures.
