Phone study:
In 2020 and 2021, we invited centenarians from all over Switzerland for a short phone interview. We will randomly select up to 20 centenarians from each canton and invite them to talk to us about their life situation on the phone. Measures include questions about basic characteristics, such as education and living situation, health, social relations and wellbeing. Starting 2022, in-person meetings were conducted with centenarians from 3 different language regions in Switzerland (cantons BE, BS, GE, TI, VD, ZH). This entailed two meetings, which we conduct at a place and time at the participants’ convenience. When possible, we conducted follow-up meetings every 6 months to learn about any changes that happened in the meantime.

The methods used for the main study will be described as soon as the data is available.
