Land cover and air pollution are associated with asthma hospitalisations: A cross-sectional study

摘要: BACKGROUND: There is increasing policy interest in the potential for vegetation urban areas to mitigate harmful effects of air pollution on respiratory health. We aimed quantify relationships between tree and green space density asthma-related hospitalisations, explore how these varied with exposure background concentrations. METHODS: Population standardised asthma hospitalisation rates (1997-2012) 26,455 residential England were merged area-level data pollutant fitted negative binomial regression models using maximum likelihood estimation obtain estimates asthma-vegetation at different levels exposure. RESULTS: Green gardens associated reductions when exposures lower but had no significant association higher. In contrast, was reduced higher lower. CONCLUSIONS: found differential natural environments high low These findings can provide evidence planning decisions which aim leverage health co-benefits from environmental improvements.
