Systematic Literature Review on the Health Effects of Long-term Exposure to Traffic-Related Air Pollution

The health effects of traffic-related air pollution continues to be of public health interest, with highest exposures in urban settings and residences in proximity to busy roadways.

Following its well-cited 2010 critical review, in early 2018 the HEI Board of Directors has appointed an expert HEI panel to review the traffic and health literature (see list of members below). Much new science has been published since the 2010 review.

The overall objective is to systematically evaluate the evidence for the associations of long-term exposure to traffic-related air pollution with selected adverse human health outcomes. Long-term exposure is defined as a duration of months to years. Results will be quantitatively combined, where appropriate, for potential use in future risk and health impact assessments of traffic-related air pollution. The focus of this systematic review is on evaluating the epidemiologic literature.

During Spring 2018, the Panel has formulated criteria for selection of health outcomes in the review, including policy and public health relevance. Selected health outcomes include all cause and cause-specific mortality, respiratory effects, cardiovascular effects, diabetes, childhood leukemia, birth and pregnancy outcomes, neurodevelopment outcomes and neurocognitive outcomes.

A systematic approach will be used to search the literature, assess study quality, summarize results, and reach conclusions about the body of evidence. To this end, a review protocol will be developed, tested and published in early 2019. The bulk of the work is scheduled for Winter 2019 through Summer 2019. Panel members will prepare sections of the draft report in Summer and Fall 2019. The HEI Special Report will undergo peer review during Winter 2020 and publication is aimed for late 2020.
