Ambient air pollution and daily mortality in ten cities of India: a causal modelling study.

ABSTRACT:

Background

The evidence for acute effects of air pollution on mortality in India is scarce, despite the extreme concentrations of air pollution observed. This is the first multi-city study in India that examines the association between short-term exposure to PM_2·5 and daily mortality using causal methods that highlight the importance of locally generated air pollution.

Methods

We applied a time-series analysis to ten cities in India between 2008 and 2019. We assessed city-wide daily PM_2·5 concentrations using a novel hybrid nationwide spatiotemporal model and estimated city-specific effects of PM_2·5 using a generalised additive Poisson regression model. City-specific results were then meta-analysed. We applied an instrumental variable causal
