Objective To explore the effect of particulate matter air pollution on residents' cardio-cerebrovascular mortality in Minhang District, Shanghai.
Methods Time-stratified case-crossover approach was used to assess the association between air particulate matters and cardio-cerebrovascular mortality from January 1, 2013 to December 31, 2014 in Minhang District, Shanghai.
Results The daily average concentrations of PM2.5 and PM10 were 56 μg/m3 and 76 μg/m3, respectively. Effects of PM10 and PM2.5 on cardiovascular and cerebrovascular mortality were statistically significant on the same day of pollution (lag 0). For PM10, an in crease of 10 μg/m3 was associated with 0.75% (95%CI:0.05%-1.46%) increase in cardio-cerebrovascular mortality; For PM2.5, an in crease of 10μg/m3 was associated with 0.87% (95%CI:0.05%-1.69%) increase in cardio-cerebrovascular mortality. Multi-pollutant analysis suggested that particulate matter's effects were enhanced after adjustment for SO2 and NO2, while the effects were weakened after adjustment for CO and O3.
Conclusion An increase of air particulate matter concentration may lead to an increase of cardio-cerebrovascular mortality of residents in Minhang District, and the effects are strongest on the same day of pollution.
