text: NEW YORK (CBSNewYork) — The key to a healthy heart? 
   
   Optimism. 
   
   As 1010 WINS’ Kevin Rincon reported, a study conducted by several universities published in the journal Health, Behavior and Policy Review found that happier people had better heart health by a ratio of 2-to-1.

   “It’s incentive to try to be optimistic, which is oftentimes difficult in the times we live in, in the world we live in and the sad news all the time,” one physician told Rincon. “But if you knew that you could actually save your life, I think that’s a pretty good prescription.” 
   
   The results of the study didn’t change for people who are rich, poor, young, old or even if they had poor mental health. 
   
   “Happier people, they live longer. They feel more fulfilled,” one New York man said. “And people that are sad, they don’t live as long.”

   THE FACTS 
   
   Laughter may not exactly be the best medicine. But a cheerful outlook on life may be good for your heart. So concludes new research on the impact of happiness and optimism on cardiovascular health. 
   
   Scientists have known about the reverse relationship between psychological health and heart health for some time; studies show that depression and anxiety can worsen outcomes for heart patients. But the findings on happiness and its medical impact over the years have not been as consistent.

   In a new analysis, researchers at Harvard sought a more definitive conclusion by reviewing the results of more than 200 studies looking at cardiovascular risks and emotional state, making this the largest report on the subject to date. Over all, the researchers found that traits like optimism and hope, and higher levels of happiness and satisfaction with one’s life, were linked with reductions in the risk of heart disease and stroke. 
   
   Such associations can be hard to untangle. Does being optimistic directly protect health, or is it the reverse — that people who watch their weight, exercise often and are generally in good health simply have more reason to be happy and optimistic? While researchers cannot say for sure, some studies have found a protective effect for optimism even after controlling for things like socioeconomic status, body weight and smoking. 
   
   One study last year, for example, looked at 8,000 people and found a lower risk of heart disease among those who reported more happiness or satisfaction in areas like career, sex life and family, but not in areas like romance and standard of living. The relationship remained after accounting for the subjects’ demographic data as well as their health behaviors. 
   
   THE BOTTOM LINE 
   
   Optimism and happiness are associated with lower cardiovascular risk, but whether a positive outlook directly protects health is still under investigation.

   CHAMPAIGN, Ill. -- People who have upbeat outlooks on life have significantly better cardiovascular health, suggests a new study that examined associations between optimism and heart health in more than 5,100 adults. 
   
   "Individuals with the highest levels of optimism have twice the odds of being in ideal cardiovascular health compared to their more pessimistic counterparts," said lead author Rosalba Hernandez, a professor of social work at the University of Illinois. "This association remains significant, even after adjusting for socio-demographic characteristics and poor mental health." 
   
   Participants' cardiovascular health was assessed using seven metrics: blood pressure, body mass index, fasting plasma glucose and serum cholesterol levels, dietary intake, physical activity and tobacco use - the same metrics used by the American Heart Association to define heart health and being targeted by the AHA in its Life's Simple 7 public awareness campaign. 
   
   In accordance with AHA's heart-health criteria, the researchers allocated 0, 1 or 2 points - representing poor, intermediate and ideal scores, respectively - to participants on each of the seven health metrics, which were then summed to arrive at a total cardiovascular health score. Participants' total health scores ranged from 0 to 14, with a higher total score indicative of better health. 
   
   The participants, who ranged in age from 45-84, also completed surveys that assessed their mental health, levels of optimism, and physical health, based upon self-reported extant medical diagnoses of arthritis, liver and kidney disease. 
   
   Individuals' total health scores increased in tandem with their levels of optimism. People who were the most optimistic were 50 and 76 percent more likely to have total health scores in the intermediate or ideal ranges, respectively. 
   
   The association between optimism and cardiovascular health was even stronger when socio-demographic characteristics such as age, race and ethnicity, income and education status were factored in. People who were the most optimistic were twice as likely to have ideal cardiovascular health, and 55 percent more likely to have a total health score in the intermediate range, the researchers found. 
   
   Optimists had significantly better blood sugar and total cholesterol levels than their counterparts. They also were more physically active, had healthier body mass indexes and were less likely to smoke, according to a paper on the research that appears in the January/February 2015 issue of Health Behavior and Policy Review. 
   
   The findings may be of clinical significance, given that a 2013 study indicated that a one-point increase in an individual's total-health score on the LS7 was associated with an 8 percent reduction in their risk of stroke, Hernandez said. 
   
   "At the population level, even this moderate difference in cardiovascular health translates into a significant reduction in death rates," Hernandez said. "This evidence, which is hypothesized to occur through a biobehavioral mechanism, suggests that prevention strategies that target modification of psychological well-being - e.g., optimism - may be a potential avenue for AHA to reach its goal of improving Americans' cardiovascular health by 20 percent before 2020." 
   
   Believed to be the first study to examine the association of optimism and cardiovascular health in a large, ethnically and racially diverse population, the sample for the current study was 38 percent white, 28 percent African-American, 22 percent Hispanic/Latino and 12 percent Chinese. 
   
   Data for the study were derived from the Multi-Ethnic Study of Atherosclerosis, an ongoing examination of subclinical cardiovascular disease that includes 6,000 people from six U.S. regions, including Baltimore, Chicago, Forsyth County in North Carolina, and Los Angeles County. 
   
   Begun in July 2000, MESA followed participants for 11 years, collecting data every 18 months to two years. Hernandez, who is an affiliated investigator on MESA, is leading a team in conducting prospective analyses on the associations found between optimism and heart health. 
   
   "We now have available data to examine optimism at baseline and cardiovascular health a decade later," said Hernandez, who expects to have an abstract completed in 2015.

   The National Heart, Lung and Blood Institute and the National Center for Research Resources funded the research.

Analyzing data on more than 5,100 adults, researchers found that the most optimistic are twice as likely to be "in ideal cardiovascular health compared to their more pessimistic counterparts," says lead author Rosalba Hernandez. "This association remains significant, even after adjusting for socio-demographic characteristics and poor mental health." Optimists were found to have better total cholesterol levels, blood sugar levels, and body-mass indexes, and to get more physical activity. "It's an incentive to try to be optimistic," CBS New York quotes a physician as saying. That's "oftentimes difficult in the times we live in, in the world we live in and the sad news all the time," the physician goes on. "But if you knew that you could actually save your life, I think that’s a pretty good prescription." Published in Health Behavior and Policy Review, the paper looks at 11 years of data on people aged 45 to 84 across six US regions. They were assessed every 18 months to two years by seven health metrics (including blood pressure, BMI, and dietary intake) and filled out surveys about their optimism and physical and mental health. It's likely the first study linking heart health and optimism in the general population, although a 2012 Harvard study did connect overall happiness with cardiovascular health, the New York Times reported at the time. (Another study finds that those who feel younger than their age will live longer.)
