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

Ongoing studies funded under this RFA

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.

University of Utrecht

This study will investigate health effects of low levels of air pollution in Europe using pooled data from 10 ESCAPE cohorts with individual covariate information, and 6 large administrative cohorts with less detailed information; resulting in a study population of about 25 million people. See also this Program Summary of HEI's research program on low levels of air pollution.

Harvard T.H. Chan School of Public Health

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.
