The aging of the population is now well-known. Life expectancy at birth has been rising steadily, with little indication that it has reached a plateau. Life expectancy at age 65 in the OECD overall is 20.5 years for women, and 17.2 for men. Yet only about half of this time spent is disability-free. A number of factors are related to better health in later life, but there is little consensus on causes – let alone preventable causes – for conditions such as Alzheimer’s disease. With the changing age structure of populations, there is concern about how society will cope with the care of the elderly. Hence there is urgency to understanding the determinants of healthy aging. The Canadian Longitudinal Study on Aging will follow 50,000 adults, aged between 45 and 85 at baseline, for at least 20 years. Its aim is to understand the dynamics of healthy aging. The study will comprise two groups: the Tracking Cohort of 20,000 who will be interviewed by telephone every three years; and the Comprehensive Cohort of 30,000 who will have a home interview and a detailed assessment at one of 11 centres across the country. The assessment includes measures of physical and psychological function, as well as taking biological samples (blood, urine, DNA). A number of challenging methodological issues have arisen on how to recruit the sample, notably whether to sample from health registries or through Random Digit Dialling. These will be discussed.
