title: [Time-series analysis of particulate matter and daily hospital visits for coronary heart disease in Yinzhou district, Ningbo area].
abstract: Objective:To explore the association between particulate matter (PM) and daily hospital visits of coronary heart diseases in Ningbo.Methods:Daily data of hospital visits from January 2014 to June 2015 (516 days in total) were obtained from the Yinzhou Health Information System in Ningbo. Daily air pollution data for PM and meteorological data were collected from the database of Ningbo Environmental Monitoring Center and Ningbo Meteorological Bureau. Time-series analysis by quasi-Poisson generalized additive model was used to examine the association between air pollution and hospital visits for coronary heart diseases by adjustment of long-term trends, seasonal patterns and meteorological variables (temperature, humidity), and day of week.Results:An increase of an IQR of PM2.5accounted for 1.98% (95%CI:-0.59%-4.63%) increase of hospital visits for coronary heart diseases. The associations between PM2.5and hospital visits for coronary heart diseases among female and the elderly (≥75 years) were stronger (ER=2.70%,95%CI:0.01%-5.47%;ER=3.35%, 95%CI:0.12%-6.69%). The effects of PM2.5~10attenuated after adjustment for PM2.5.Conclusion:PM2.5had short-term effects on daily hospital visits for coronary heart diseases in Ningbo, and such association was stronger among female and the elderly.
