Lifestyle, social factors, and survival after age 75: population based study

摘要

STUDY QUESTION Do lifestyle and social factors after ages 75 and 85 years affect longevity?SUMMARY ANSWER Lifestyle behaviours such as not smoking and physical activity were associated with longer survival, even after age 75. A low risk profile added five years to women's lives and six to men's lives. These associations, although attenuated, were also present among the oldest old (>=85 years) and in people with chronic health conditions.WHAT IS KNOWN AND WHATTHIS PAPER ADDS: It is uncertain whether lifestyle and social factors predict mortality among the oldest old because of mixed results. The associations of leisure activity and not smoking with increased life expectancy are still present among the oldest old and those with chronic conditions.
