Ambient Ozone Pollution and Daily Mortality: A Nationwide Study in 272 Chinese Cities.

ABSTRACT:

Background

Few large multicity studies have been conducted in developing countries to address the acute health effects of atmospheric ozone pollution.

Objective

We explored the associations between ozone and daily cause-specific mortality in China.

Methods

We performed a nationwide time-series analysis in 272 representative Chinese cities between 2013 and 2015. We used distributed lag models and over-dispersed generalized linear models to estimate the cumulative effects of ozone (lagged over 0-3 d) on mortality in each city, and we used hierarchical Bayesian models to combine the city-specific estimates. Regional, seasonal, and demographic heterogeneity were evaluated by meta-regression.

Results

At the national-average level, a 10-μg/m³ increase in 8
