They also evaluated how lifestyle factors could affect the results. The investigators considered other factors that could lead to a longer life span, including age, education, marital status, annual family income, mental health, and more. The women were ages 50 to 79 when they enrolled in the project between 19. The women were 83% non-Hispanic white, 9% Black, 4% Hispanic/Latina, 3% Asian, less than 1% American Indian or Alaska native, and the remainder self-identified as “other.” Koga and colleagues studied 159,255 women participating in the Women’s Health Initiative. The current study, published in Journal of the American Geriatrics Societyis among the first to link optimism to longevity in a racially and ethnically diverse population. Other researchers, for example, previously reported that optimism was associated with a 15% longer lifespan among mainly white women who were followed for up to 10 years. In part, she says, this may be because people often consider optimism to increase the ability to solve problems and tackle challenges.Īlthough not the first study to link optimism to longevity, most previous work focused primarily on non-Hispanic white people. Instead, Koga says, they find ways to see the potential for more positive things to happen in the future. “Most research suggests that individuals who are more optimistic are not unrealistic,” says lead investigator Hayami Koga, MD. In a study of nearly 160,000 women, people with the highest optimism ratings had a 5.4% longer lifespan than those considered less optimistic.

New research shows that people who are more optimistic may actually live longer. J– Want to live longer? You might want to try improving your outlook on life.
