Objective:

This project is one of four projects under Theme II: Identifying Populations Susceptible to the Health Effects of Particulate Air Pollution of our proposal. As part of this project we will follow up the Six Cities Study cohort up to 24 years in an effort to assess the cumulative effect of long-term exposures on the incidence of lung cancer, nonmalignant respiratory disease, cardiovascular disease, and cause-specific mortality. Another objective of this project is to estimate the years lost associated with particulate exposure.

Progress Summary:

Vital status was determined for the 8111 participants in the Harvard Six Cities adult cohort for an additional 9 years of follow-up (1990-1998). We identified 1430 additional deaths, bringing the total to 2737 deaths. Survival analyses of all-cause mortality shows that life expectancy continues to be reduced in the more polluted cities, with the relative ranking of the survival the same as in the original published analyses. We also are investigating how the risk varies with the baseline age of the members of the cohort.

Future Activities:

In the coming year, we will construct an air pollution timeline for each city, analyze cause-specific mortality, and estimate the net years of life lost attributable to particulate air pollution.
