14-3 Assessing Health Effects of Long-term Exposure to Low Levels of Ambient Air Pollution

Status: 
Not Active
Number: 
RFA 14-3

HEI is seeking to fund studies to assess health effects of long-term exposure to low levels of ambient air pollution, including studies to evaluate all-cause and cause-specific mortality and morbidity endpoints. RFA 14-3 solicits studies to analyze and evaluate exposure-response function(s) for PM2.5 and other pollutants at levels currently prevalent in North America, Western Europe and other high-income regions and related questions about adverse health effects at low levels of ambient air pollution. In addition, RFA 14-3 solicits studies to develop methods required for, and specifically suited to, conducting such research. At the outset, HEI expects to fund a small number of large studies for up to 4 years. HEI also expects to fund some smaller-scale methods development studies. Fall 2014 RFA booklet

Identifying the shape of the association between long-term exposure to low levels of ambient air pollution and the risk of mortality: An extension of the Canadian Census Health and Environment Cohort using innovative data linkage and exposure methodology

Michael Brauer
, 

University of British Columbia, Canada

This study will investigate mortality effects of low levels of air pollution in Canada using Canadian Census data from about 6 million people. The shape of the exposure-response function will be characterized using newly developed flexible non-linear exposure-response functions.

Assessing adverse health effects of long-term exposure to low levels of ambient pollution

Francesca Dominici
, 

Harvard T.H. Chan School of Public Health

Antonella Zanobetti
, 

Harvard T.H. Chan School of Public Health

This study will examine health effects of low levels of air pollution in the US using data from about ~56 million people enrolled in Medicare and Medicaid. In addition, they will develop new causal modeling methods to characterize the shape of the exposure-response function. See also this Program Summary of HEI's research program on low levels of air pollution.

Research Report 200 describes the first-phase results of a study examining any association between exposure to low levels of air pollution — both PM2.5 and O3 — and all-cause mortality in a population of 61 million Medicare enrollees residing in the continental United States. The report also presents the detailed Commentary on the study by HEI’s Low-Exposure Epidemiology Studies Review Panel.

Research Report 203 describes the first-phase results of a study evaluating the relationship between long-term exposure to low concentrations of PM2.5 and non-accidental mortality, including a characterization of the shape of the concentration–response functions, in a large population-based cohort (~9 million adults) in Canada. The report also presents the detailed Commentary on the study by HEI’s Low-Exposure Epidemiology Studies Review Panel.
