Sources of Recruitment

General Population
  • Selected sample
Supplementary Information
The sample was stratified by sex with an aim to recruit 200 men and 200 women at each site. Participants were recruited through neighborhood primary care center registers at Tirana, Manizales and Natal. At these sites, a random sample of elderly people registered at the health centers was drawn and participants were approached directly by our interviewers to invite them to participate in the study. In Kingston and Saint-Hyacinthe, participants received a letter from their primary care doctors inviting them to contact our field coordinator to make an appointment for the home visits. In choosing the study neighborhoods, the extremes of the socioeconomic spectrum (the wealthy and the very poor areas) were purposefully avoided.
