Personality, not just diet, linked to living past 100 in Sardinia study

Beyond diet and physical activity, personality traits are emerging as a significant factor in healthy aging and longevity, according to new research.

A study conducted in Sardinia, Italy, one of the world's "Blue Zones" known for its high concentration of centenarians, identified a crucial, often overlooked element: personality. Researchers found that adaptive personality traits and effective coping mechanisms play a vital role in encouraging an active lifestyle, which is strongly linked to living a long and healthy life.

The study, led by psychologist Marija Kjara Fastame from the University of Cagliari, suggests that personality influences how individuals respond to life's challenges and interact with their surroundings. These influences, in turn, shape behaviors and habits that help people remain active as they age. "These findings indicate that a combination of adaptive personality traits and coping resources promotes a more active lifestyle," the researchers stated in their paper published in the International Journal of Applied Positive Psychology.

Investigating the role of personality in longevity is complex, as factors like genetics and environment also play significant roles. However, the unique demographics of Blue Zones offer researchers a valuable opportunity to isolate specific influences. The Sardinian study focused on 125 adults aged 71 to 101, comparing those living within the Blue Zone to residents of a nearby community with similar socioeconomic and cultural backgrounds. Participants underwent various assessments to evaluate their mental and physical health, lifestyle, and their five core personality traits: openness, conscientiousness, extraversion, agreeableness, and neuroticism.
