Lower income means higher risk for heart disease

26.09.2006
Protein linked to heart disease found to be more prevalent in low-income people, minorities and women; findings may help explain why the poor age faster, say USC and UCLA researchers

Low-income adults are more likely to have very high levels of C-reactive protein (CRP), a risk factor for heart disease, according to a study led by researchers at the University of Southern California.

The study, published in the current issue of Brain, Behavior and Immunity, finds that among adults with income levels at or below the poverty line, 15.7 percent had very high levels of CRP, compared to only 9.1 percent of those in families above the poverty line.

"We have long known that poor people have worse health," said Eileen Crimmins, corresponding author and professor in the USC Leonard Davis School of Gerontology. "This paper provides evidence that people living at or near the poverty line are almost twice as likely to have very high CRP, which poses risks for long-term, chronic conditions like heart disease and cognitive loss. This may be one of the explanations for why poor people age faster."

CRP is produced as part of the immune response to inflammation. In healthy individuals, CRP levels return to normal after infection or injury subsides. However, some people have chronically elevated levels of CRP. Recent studies have shown high levels of CRP to be a useful predictor of heart disease.

Recent illness, chronic conditions and lifestyle account for some but not all of the explanations for the association between high CRP levels and socioeconomic standing.

"We found that even after accounting for various risk factors, people in poverty still had higher CRP," said Dawn Alley, another corresponding author and a recent doctoral graduate from the USC Davis School. "This suggests that even beyond issues like health behaviors and chronic conditions, there is something about poverty that makes people sick, and at least part of this effect is working through CRP."

The study also found that African Americans, Hispanics and women are more likely to have high levels of CRP, and that obesity is the largest contributor to above normal CRP levels.

The findings, which were funded by the National Institutes of Health, provide a better understanding about risk factors for poor health outcomes later in life.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
