Healthy aging among centenarians and near-centenarians: Findings from the Georgia Centenarian Study.

The Georgia Centenarian Study is one of the earliest comprehensive studies on centenarians. Based on the Georgia model of adaptation, the primary purpose of this study was to assess the health and well-being of our oldest population, with a focus on several primary adaptation areas: genetics and family longevity, environmental support, individual characteristics, cognitive and behavioral skills, health behaviors, and physical and mental health, including overall life satisfaction. The results of the three Georgia Centenarian sub-studies indicate that genetic and environmental variables play an important role in determining different levels of healthy aging, but they also highlight relevant mediating and moderating effects in a network of interrelating adaptation components.
