Abstract

The overall goal was to establish a genetic-epidemiological database to shed light on the aging process among the extremely old, focusing on physical and cognitive functioning. In the first wave 2,262 Danes born in 1905 participated in a home-based 2-hour multidimensional interview, including cognitive and physical performance tests and collection of DNA, carried out by lay interviewers. Population-based registers were used to evaluate representativeness.

The first wave took place in 1998 and participants were followed-up in 2000 and 2003. In 2005 all the surviving birth cohort members were invited to participate irrespective of previous participation:

  • Wave 1: 2262 participants (1653 with biological sample)
  • Wave 2: 1086 participants
  • Wave 3: 437 participants
  • Wave 4: 256 participants
