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.
The Lc65+ study was launched in 2004 at the Institute of Social and Preventive Medicine (IUMSP) of the Lausanne University Hospital Center (CHUV). The cohort is based on a representative sample of residents of the city of Lausanne (canton Vaud, Switzerland, 120’000 inhabitants) born before, during, and after World War II.
The long term goals of this public health project are improvements in the quality of life of older persons by preventing frailty and its adverse effects early.
To compare health evolution and health care service utilization from age 65 onwards in three consecutive samples issued from the general population
To improve our understanding of the frailty process and its consequences, as well as related needs for care, based on longitudinal data
To design preventive interventions aimed at avoiding or delaying unfavorable outcomes in older age
