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

Abstract

BackgroundNumerous studies have found associations between ambient fine particulate matter (PM2.5) and increased mortality risk. However, little evidence is available on associations between PM2.5 and years of life lost (YLL). We aimed to estimate the YLL due to chronic obstructive pulmonary disease (COPD) mortality related to ambient PM2.5 exposure.MethodsA 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 PM2.5 on YLL and daily death of COPD were estimated, after controlling long term trend, meteorological index and other confounders.ResultsThe impact of PM2.5 on YLL due to COPD lasted for 5 days (lag 0–4). Per 10 μg/m3 increase in PM2.5 was associated with 0.91 (95%CI: 0.16, 1.66) years increase in YLL. The excess YLL of COPD mortality were 8206 years, and 0.38 day per person in Ningbo from 2011 to 2015. The exposure-response curve of PM2.5 and YLL due to COPD showed a non-linear pattern, with relatively steep at low levels and flattened out at higher exposures.. Furthermore, the effects were significantly higher in the elderly than those in the younger.ConclusionsOur findings explored burden of PM2.5 on YLL due to COPD and highlight the importance and urgency of ambient PM2.5 pollution control and protection of the vulnerable populations.Electronic supplementary materialThe online version of this article (doi:10.1186/s12940-017-0253-1) contains supplementary material, which is available to authorized users.

Fine particulate matter (PM2.5): The culprit for chronic lung diseases in China

“…An increase of 10 μg/m 3 in PM 2.5 was associated with an increase of 0.91 (95% CI : 0.16–1.66) years in YLL. 79 In a 9-year prospective cohort study, use of improved cooking fuels and kitchen ventilation were correlated with a reduction in forced expiratory volume in 1 second (FEV 1 ). FEV 1 was reduced by 12 mL/y (95% CI , 4–20 mL/y) and 13 mL/y (95% CI , 4–23 mL/y) in subjects who used clean fuels and improved ventilation, respectively, compared to those with no intervention after adjustment for confounders.…”

Temporal and Spatial Distribution Characteristics of Atmospheric Particulate Matter (PM10 and PM2.5) in Changchun and Analysis of Its Influencing Factors

“…PM pollution affects urban and regional air quality [5][6][7] and visibility [8][9][10], and even plays an important role in global climate change [11][12][13]. PM at high concentrations can significantly increase the incidence of human respiratory and cardiovascular diseases and mortality [14][15][16]. Because of the harm of PM pollution, people have drawn significant attention to it in recent years [17,18].…”

Development and testing of the reliability and validity of the adolescent haze related knowledge awareness assessment scale (AHRKAAS)

“…[ 5 ]. Some studies have highlighted the importance and urgency of air pollution control in China and have highlighted the protection of vulnerable populations [ 29 , 30 ]. Therefore, by fully mobilizing the enthusiasm of adolescents, and by strengthening their awareness of health protection against haze, the harm caused by haze to adolescents may be reduced.…”
