The short term burden of ambient fine particulate matter on chronic obstructive pulmonary disease in Ningbo, China.

ABSTRACT:

Background

Numerous studies have found associations between ambient fine particulate matter (PM_2.5) and increased mortality risk. However, little evidence is available on associations between PM_2.5 and years of life lost (YLL). We aimed to estimate the YLL due to chronic obstructive pulmonary disease (COPD) mortality related to ambient PM_2.5 exposure.

Methods

A time-series study was conducted based on the data on air pollutants, meteorological conditions and 18,472 registered COPD deaths in Ningbo, China, 2011-2015. The effects of PM_2.5 on YLL and daily death of COPD were estimated, after controlling long term trend, meteorological index and other confounders.

Results

The impact of PM_2.5 on YLL due to COPD lasted
