(Press-News.org) PROVIDENCE, R.I. [Brown University] — Pay attention to the implication of these new research results: People who pay more attention to their feelings and experiences tend to have better cardiovascular health.
As noted more precisely in a new study in the International Journal of Behavioral Medicine, researchers at Brown University found a significant association between self-reported "dispositional mindfulness" and better scores on four of seven cardiovascular health indicators, as well as a composite overall health score. Dispositional mindfulness is defined as someone's awareness and attention to what they are thinking and feeling in the moment.
The study is the first to quantify such an association between mindfulness and better cardiovascular health, said study lead author Eric Loucks, assistant professor of epidemiology in the School of Public Health. It's an encouraging link for health promotion, because mindfulness can be enhanced with training.
"Mindfulness is changeable, and standardized mindfulness interventions are available," Loucks said. "Mostly they've been looked at for mental health and pain management, but increasingly they are being looked at for cardiovascular risk factors such as obesity, smoking, and blood pressure."
The connection may come about because people who are attuned to their present feelings may be better at minding and managing the various cravings — for salty or sugary foods or cigarettes or even a spell on the couch — that undermine health, Loucks said. Mindfulness interventions, for example, have already shown efficacy in helping people to quit smoking.
Measuring mindfulness and health
In the study, Loucks and his colleagues asked 382 participants in the broader New England Family Study to answer the 15 questions of the Mindful Attention Awareness Scale (MAAS).
MAAS questions, rated on a six-point scale from "almost always" to "almost never" include "I find it difficult to stay focused on what's happening in the present" and "I tend not to notice feelings of physical tension or discomfort until they really grab my attention."
The participants also underwent tests to determine ratings on seven indicators of cardiovascular health, as suggested by the American Heart Association: smoking avoidance, physical activity, body mass index, fruit and vegetable consumption, cholesterol, blood pressure, and fasting blood glucose. The researchers also noted the participants' age, race, sex, education and scores on standardized scales of depression, and sense of control in their lives.
In their analysis of the data, Loucks and his team examined the association between the degree of self-reported mindfulness and the scores on each of the seven cardiovascular health indicators, accounting for age, sex, and race. They also calculated a composite score of the health indicators.
Participants with high MAAS scores had an 83 percent greater prevalence of good cardiovascular health (as measured by the composite score) compared to those with relatively low MAAS scores. High vs. low MAAS scores were associated with significantly higher cardiovascular health on four of the seven individual indicators: BMI, physical activity, fasting glucose, and avoiding smoking.
That higher mindfulness did not also associate with higher scores for blood pressure or cholesterol may be because neither of those health indicators directly affect how someone feels in a typical moment, whereas smoking, obesity (and closely related fasting glucose), and physical activity are all much more explicitly evident experiences for the self.
Meanwhile, fruit and vegetable consumption, an indicator of diet quality, showed a positive association with higher MAAS scores, but with too wide a range of uncertainty to be considered statistically significant.
Loucks said the next step in his research is to begin testing whether improving mindfulness can increase cardiovascular health indicators. He said he hopes to launch randomized controlled trials with long-term follow-up (because behavioral interventions often look good in the short term but then don't last).

A study led by the researcher at the Institute of Biomedical Research (IDIBELL), Isabel Fabregat, could serve to select patients with hepatocellular carcinoma unresponsive to most frequently used drug in liver cancer: sorafenib. The study, published in the International Journal of Cancer describes how tumor cells that have a less differentiated phenotype (mesenchymal) and expresses CD44, do not respond to Sorafenib action.
Difficult treatment
Hepatocellular carcinoma is one of the cancers with the worst prognosis and more difficult treatment. Surgery is only possible ...
This news release is available in German. Bio-engineers are working on the development of biological computers with the aim of designing small circuits made from biological material that can be integrated into cells to change their functions. In the future, such developments could enable cancer cells to be reprogrammed, thereby preventing them from dividing at an uncontrollable rate. Stem cells could likewise be reprogrammed into differentiated organ cells.
The researchers have not progressed that far yet. Although they have spent the past 20 years developing individual ...
Scientists at the University of Manchester, King's College London and the University of Liverpool have found that an infant's preference for a person's face, rather than an object, is associated with lower levels of callous and unemotional behaviors in toddlerhood.
The study, which was published in Biological Psychiatry, assessed if 213 five-week-old infants spent longer tracking a person's face compared to an inanimate object – in this case a red ball.
The researchers showed that greater tracking of the face relative to the ball was linked to lower callous unemotional ...

Martín Olazar, a UPV/EHU chemical engineer, has designed a fundamental process for producing alternatives to petroleum in sustainable refineries. As Olazar himself pointed out, one of the unavoidable conditions of the process is not to harm the environment. This researcher has developed a reactor based on conical spouted beds which, by means of flash or rapid pyrolysis, produces fuels and raw materials using various types of waste.
Olazar has developed two lines, depending on the type of waste: one uses biomass; the ...
The average U.S. doctor spends 16.6 percent of his or her working hours on non-patient-related paperwork, time that might otherwise be spent caring for patients. And the more time doctors spend on such bureaucratic tasks, the unhappier they are about having chosen medicine as a career.
These are some of the findings of a nationwide study by Drs. Steffie Woolhandler and David Himmelstein, internists in the South Bronx who serve as professors of public health at the City University of New York and lecturers in medicine at Harvard Medical School. The study was published ...
MANHATTAN, Kansas — Football teams are claiming it improves their athletic performance, and according to new research from Kansas State University, it also benefits heart failure patients. The special ingredient: beetroot.
Recently, the Auburn University football team revealed its pregame ritual of taking beetroot concentrate, or beet juice, before each game. The juice may have contributed to the team's recent winning season — and one exercise physiologist who has been studying the supplement for several years says that may be the case.
"Our research, published ...
Scientists have identified 181 California dams that may need to increase water flows to protect native fish downstream. The screening tool developed by the Center for Watershed Sciences at the University of California, Davis, to select "high-priority" dams may be particularly useful during drought years amid competing demands for water.
"It is unpopular in many circles to talk about providing more water for fish during this drought, but to the extent we care about not driving native fish to extinction, we need a strategy to keep our rivers flowing below dams," said lead ...
Future prevention and treatment strategies for vascular diseases may lie in the evaluation of early brain imaging tests long before heart attacks or strokes occur, according to a systematic review conducted by a team of cardiologists, neuroscientists, and psychiatrists from Icahn School of Medicine at Mount Sinai and published in the October issue of JACC Cardiovascular Imaging.
For the review, Mount Sinai researchers examined all relevant brain imaging studies conducted over the last 33 years. They looked at studies that used every available brain imaging modality in ...
No-till farming, a key conservation agriculture strategy that avoids conventional plowing and otherwise disturbing the soil, may not bring a hoped-for boost in crop yields in much of the world, according to an extensive new meta-analysis by an international team led by the University of California, Davis.
As the core principle of conservation agriculture, no-till has been promoted worldwide in an effort to sustainably meet global food demand. But after examining results from 610 peer-reviewed studies, the researchers found that no-till often leads to yield declines compared ...
University of Southampton scientists have designed a new experiment to test the foundations of quantum mechanics at the large scale.
Standard quantum theory places no limit on particle size and current experiments use larger and larger particles, which exhibit wave-like behaviour. However, at these masses experiments begin to probe extensions to standard quantum mechanics, which describe the apparent quantum-to-classical transition.
Now, Southampton researchers, with colleagues from the University of Duisburg-Essen in Germany, have designed a new type of experiment ...
