Higher levels of optimism were associated with longer lifespan and living beyond age 90 in women across racial and ethnic groups in a study led by researchers at Harvard T.H. Chan School of Public Health.
“Although optimism itself may be affected by social structural factors, such as race and ethnicity, our research suggests that the benefits of optimism may hold across diverse groups,” said Hayami Koga, a PhD student in the Graduate School of Arts and Sciences studying in the Population Health Sciences program in partnership with Harvard Chan School and lead author of the study. “A lot of previous work has focused on deficits or risk factors that increase the risks for diseases and premature death. Our findings suggest that there’s value to focusing on positive psychological factors, like optimism, as possible new ways of promoting longevity and healthy aging across diverse groups.”
