Supplementary Information
The first stage of sampling and recruitment in the Lc65+ study took place in 2004. Participants were selected by simple random sampling of city residents comprising 3236 individuals born between 1934 and 1938 extracted by the Population Office in April 2003. In March 2004, all selected individuals received a support letter from the Surgeon General of the Canton of Vaud, followed one week later by a mailing including a presentation of the study, an initial self-administered questionnaire, and a stamped return envelope. Non-respondents received two follow-up mailshots with the same contents. The last mailing included an anonymous form for reporting refusals and corresponding reasons.

Supplementary Information
The third stage of sampling and recruitment in the Lc65+ study took place in 2014, with a similar procedure to that followed in the first and second stages. As participation rates were expected to decline over time and particularly in baby boomers, the number of invited persons was somewhat higher in sample 3.
