Longevity at sixty: factors influencing life expectancy in old age

Abstract

While longevity is increasing in general, factors that can prolong the life of older adults constitute an area to explore. At the same time, it is not just adding years to life, but having increased periods of disability-free life, with increased productivity and functioning. Many factors influence remaining life expectancy at the age of 60 which could be biological, clinical, and psychosocial in nature. The usual ingredients that support a healthy life may help in older adults as well, however, specific efforts to prevent diseases and adequate management of existing physical and mental illnesses are the key factors; along with diet and nutrition, exercise, smoking cessation, socialisation, availability of medical and nursing facilities, and appropriate health policies are other determinants. Efforts to improve health and a disability-free life after the age of 60 need further understanding and research.
