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 2018 the HEI Board of Directors appointed an expert HEI panel to review the scientific literature on traffic-related air pollution and health (see list of members below). Much new science has been published since the 2010 review.

The overall objective is to systematically evaluate the epidemiological evidence regarding the associations between long–term exposure to traffic-related air pollution and selected adverse health outcomes. The Panel will draw conclusions about the confidence in the strength of the evidence, discuss strengths and limitations of the existing studies, and make recommendations for future research. Results will be quantitatively combined to evaluate the strength of the evidence, where appropriate. In addition, the quantitative results of the review may be useful for future risk and health impact assessments of traffic-related air pollution.

The Panel 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, and birth outcomes.

The Panel is using a systematic approach to search the literature, assess study quality, summarize results, and reach conclusions about the body of evidence. To this end, a review protocol (pdf) has been published. The protocol has been registered in Prospero.

The review is currently well underway. The HEI Special Report is expected to undergo peer review in 2020 and publication is aimed for Summer 2021.
