Researchers identify personality traitsApril 06, 2009(Boston) - Researchers from Boston University School of Medicine's (BUSM) New England Centenarian Study have noted specific personality traits associated with healthy aging and longevity amongst the children of centenarians. The work was conducted in collaboration with scientists from the National Institute on Aging. These findings currently appear on-line in the Journal of the American Geriatrics Society. Previous research on siblings and offspring of centenarians have documented that exceptional longevity runs strongly in families. Studies of the offspring of centenarians showed that their mortality is 120 percent lower than other members of their birth cohort and that they also have markedly lower prevalence rates and delayed onsets of cardiovascular disease, hypertension, and diabetes mellitus. Because personality traits have been shown to have substantial heritable components, the researchers hypothesized that certain personality features may be important to the healthy aging observed in the offspring of centenarians. Using the NEO-Five-Factor Inventory (NEO-FFI) questionnaire, measures of the personality traits for neuroticism, extraversion, openness, agreeableness, and conscientiousness were obtained from 246 (125 women and 121 men) unrelated offspring of centenarians with an average age of 75. Both the male and female offspring of centenarians scored in the low range of published norms for neuroticism and in the high range for extraversion. The women also scored comparatively high in agreeableness. Otherwise, both sexes scored within normal range for conscientiousness and openness, and the men scored within normal range for agreeableness. According to the researchers, personality traits in the offspring of centenarians appear to have distinctive characteristics that may have important implications for their longevity. "Interestingly, whereas men and women generally differ substantially in their personality characteristics, the male and female offspring tended to be similar, which speaks to the importance of these traits, irrespective of gender, for health aging and longevity. It's likely that the low neuroticism and higher extraversion will confer health benefits for these subjects," said senior author Thomas Perls, MD, MPH, director of the New England Centenarian Study. "For example, people who are lower in neuroticism are able to manage or regulate stressful situations more effectively than those with higher neuroticism levels. Similarly, high extraversion levels have been associated with establishing friendships and looking after yourself," he said. Perl's added, "These findings suggest that personality is an important characteristic to include in studies that assess genetic and environmental determinants of longevity. Such studies are currently underway." Boston University |

Faced with health problems, financial issues and the death of a spouse or loved one, many adults 65 years and older suffer from depression. While research is emerging to help this group understand and treat the problem, another group - centenarians - has been left largely in the dark. Einstein researchers discover gene mutations linked to longer lifespans Mutations in genes governing an important cell-signaling pathway influence human longevity, scientists at the Albert Einstein College of Medicine of Yeshiva University have found. Studies identify modifiable factors associated with exceptionally long life A healthy lifestyle during the early elderly years-including weight management, exercising regularly and not smoking-may be associated with a greater probability of living to age 90 in men, as well as good health and physical function. Einstein researchers use novel approach to uncover genetic components of aging People who live to 100 or more are known to have just as many-and sometimes even more-harmful gene variants compared with younger people. Gene tied to longevity also preserves ability to think clearly A gene variant linked to living a very long life-to 90 and beyond-also serves to help very old people think clearly and retain their memories, according to new research by scientists at the Albert Einstein College of Medicine of Yeshiva University. Longevity gene also protects memory, cognitive function A gene variation that helps people live into their 90s and beyond also protects their memories and ability to think and learn new information, according to a study published in the December 26, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology. Wear and tear of stress: the psychoneurobiology of aging Age may be more related to reactions to stress and the absence of disease rather than to a person's chronological age, say leading researchers in the fields of neurobiology and psychoneuroendocrinology. What are your odds of surviving into your hundreds? A genetic factor that protects you against heart disease during middle age could reduce the odds that you'll celebrate your hundredth birthday. Research published in BMC Medical Genetics shows that a genetic trait, which is rarely found in centenarians, is associated with lower cholesterol levels. The risk of suffering from heart disease is increased by a number of factors, including having high levels of low-density lipoprotein cholesterol in your blood. The main component of low-density lipoprotein is apoliprotein (b) whose quality and quantity are related to the quality and expression of the APOB genes you have.
