Abstract:
|
The American Cancer Society (ACS) study and the Harvard Six Cities study (SCS) are the two landmark cohort studies for estimating the chronic effects of fine particulate matter (PM2.5) on mortality. To date, no comparative analysis of these studies has been carried out using a different study design, study period, data, or modeling approach. We estimate the chronic effects of PM2.5 on mortality for the period 2000--2002 using mortality data from Medicare and PM2.5 levels from the National Air Pollution Monitoring Network for the same counties included in the SCS and the ACS. We use a log-linear regression model which controls for individual-level and area-level covariates. The results are similar to those reported by the original SCS and ACS indicating that fine particulate matter is still significantly associated with mortality when more recent air pollution and mortality data are used.
