Giving Compass' Take:
- A recent study shows a higher risk of mortality for those living with chronic inflammation and in poverty, based on data representing 95 million Americans ages 40 and over.
- How do the social determinants of health have an impact on mortality risks? How are poverty and health inexplicably tied?

People with chronic inflammation who live in poverty have more than double the risk of dying from heart disease and nearly triple the risk of dying from cancer within the next 15 years, a new study shows.
The findings are based on data representing 95 million Americans ages 40 and over.
While chronic inflammation and poverty are each known to increase mortality risk, when combined, the two factors appear to have a synergistic effect, producing a greater increase in risk than if the individual effects of the two factors were merely added together, according to the study in the journal Frontiers in Medicine.
“There is a lot of existing evidence that chronic inflammation can lead to disease,” says lead author Arch Mainous III, a professor in the department of health services research, management and policy in the University of Florida College of Public Health and Health Professions and vice chair for research in the College of Medicine’s department of community health and family medicine.
“We became interested in the potential interplay of chronic inflammation with poverty, which tends to increase inflammation in its own right through factors such as chronic stress. We found that poverty and high levels of inflammation act synergistically, giving people with both factors basically a double whammy. It makes them far more likely to die and in a relatively short period of time, just 15 years.”
Acute inflammation is part of the body’s healthy short-term immune response to fighting infection, toxins, or other foreign substances that may enter the body. Chronic inflammation, however, lasts for months or years and has been shown to increase the risk for developing conditions such as cancer, heart disease, Type 2 diabetes, and kidney disease. Another new study led by Mainous indicates that 34.6% of US adults have systemic inflammation.
Chronic inflammation can be caused by a host of lifestyle, physiological and environmental factors, such as poor diet, stress, lack of physical activity, smoking, aging, obesity, autoimmune disorders, and exposure to toxins in the environment.
The findings from the new study highlight the need for routine chronic inflammation screenings in vulnerable populations to limit what are, in many cases, preventable deaths, Mainous says. Currently, there are no clinical guidelines for chronic inflammation screening.
“Investigators have been studying chronic inflammation for 25 years and we have a lot of data on its role in the disease pathway and mortality,” Mainous says. “We know it’s a problem, but we don’t do anything about it. We need to translate the basic science on chronic inflammation to the doctor’s office through the creation of screening guidelines so physicians can identify chronic inflammation in their patients and work to treat the underlying causes.”
