DALLAS — The impact of particulate matter air pollution on death and disability is on the rise worldwide, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.
Previous research established the association of particulate matter (PM) pollution to CVD death and disability. However, questions remain about the worldwide impact from this type of pollution and how it has been changing over time, the study authors noted.
“We focused on examining the burden globally because particulate matter pollution is a widespread environmental risk factor that affects all populations worldwide, and understanding its impact on cardiovascular health can help guide public health interventions and policy decisions,” said Farshad Farzadfar, M.D., M.P.H., D.Sc., senior author of the study and a professor of medicine in the non-communicable diseases research center of the Endocrinology and Metabolism Research Institute at Tehran University of Medical Sciences in Iran.
The researchers analyzed PM pollution as a risk factor for death and disability using freely available data from 204 countries collected between 1990 and 2019 and detailed in the Global Burden of Disease (GBD) study. Exposure to PM pollution was estimated using a tool from the 2019 update to the GBD study that incorporated information from satellite and ground-level monitoring, computer models of chemicals in the atmosphere and land-use data.
Among the many types of heart disease, the current analysis of cardiovascular disease is restricted to stroke and ischemic heart disease (a lack of blood and oxygen supply to portions of the heart, usually due to plaque build-up in the arteries) because the 2019 GBD study on the global burden of disease attributed to PM pollution only examined these two diagnoses. The Institute for Health Metrics and Evaluation (IHME), which provides the GBD estimates, only reports data for a certain risk factor if there is a large body of evidence about its association with a disease, Farzadfar noted.
“Until now, only the association of PM pollution with ischemic heart disease and stroke has been demonstrated in a large number of studies,” Farzadfar said. “The IHME may include other CVDs in the future. Moreover, ischemic heart disease and stroke contribute to a significant majority of CVDs, and our estimates, despite having limitations, may be used as a good estimate of PM pollution burden on CVDs.”
The investigators analyzed changes over time in years of life lost due to premature death (YLLs), years lived with disability (YLDs) and disability-adjusted life years (DALYs). DALYs is a measure that considers both the loss of life and the impact on quality of life to assess the full impact of a health condition on a population. The cardiovascular disease burden was assessed both overall and with age standardization, which compares health outcomes across a population with a wide range of ages.
The analysis found:
“The declines in deaths may be considered positive news, as they indicate improvements in health care, air pollution control measures and access to treatment. However, the increase in disability-adjusted life years suggests that although fewer people were dying from cardiovascular disease, more people were living with disability,” Farzadfar said.
The researchers also found that between 1990 and 2019, age-standardized CVD death and disability attributed to outdoor PM pollution rose by 8.1%, while age-standardized cardiovascular death and disability attributed to household PM pollution, which is produced by solid cooking fuels such as coal, charcoal, crop residue, dung and wood, fell by 65.4%.
“The reason for the decrease in the burden of household air pollution from solid fuels might be better access and use of cleaner fuels, such as refined biomass, ethanol, liquefied petroleum gas, solar and electricity. Moreover, structural changes, such as improved cookstoves and built-in stoves, chimney hoods and better ventilation, might be effective in reducing pollution exposure to solid fuels. Finally, the effects of educational and behavioral interventions should be considered,” Farzadfar said. “The shifting pattern from household air pollution due to solid fuels to outdoor, ambient PM pollution has important public policy implications.”
In a 2020 scientific statement and a 2020 policy statement, the American Heart Association details the latest science about air pollution exposure and the individual, industrial and policy measures to reduce the negative impact of poor air quality on cardiovascular health. Reducing exposure to air pollution and reversing the negative impact of poor air quality on cardiovascular health, including heart disease and stroke, is essential to reducing health inequities in Black and Hispanic communities, those that have been historically marginalized and under-resourced, and communities that have the highest levels of exposure to air pollution.
The study has several limitations. Because the assessment of exposure to particulate matter pollution in the study is based on regional estimates, it may not accurately reflect individual exposure. In addition, results from this analysis of the association between particulate matter pollution and cardiovascular outcomes may not be generalizable to other health conditions or other pollutants.

National football star Aaron Rodger’s football career may be over, but maybe not. It’s hard to keep a good man down. Sometimes, there is too much to overcome to come back.
Many of us watched the mega media debut of Rodgers as a New York Jets quarterback. His move from Green Bay after 18 seasons catapulted him to New York City celebrity status. He came to the Jets after a hugely successful career with the Packers. His accomplishments were many and include a Super Bowl ring. He was received the Super Bowl MVP award and four NFL MVP awards. He was touted as the man who would revitalize the Jet’s program and lead them to glory.
Rodger’s financial package to make the move from Wisconsin to the Jet’s program was $75 million dollars over two years. The money is guaranteed even though he may never play again. Rodgers reportedly took a salary cut to make the move.
He is the author of 13 books including Uncommom Sense, the Spiritual Chocolate series, Grandpa's Store, Minister's Guidebook insights from a fellow minister. His column is published weekly in over 600 publications in all 50 states. The views expressed are those of the author and are not necessarily representative of any other group or organization.
