Lc65+ study

The Lausanne cohort 65+ (Lc65+) study is a research platform that aims to gain new knowledge on frailty in the general population from the age of 65 years onwards. Manifestations of frailty, medical and psycho-social risk factors, and the effects of frailty on health, functional status, and use of health services are central to the research conducted in the Lc65+ project.
