Declarations
:
: There are no conflicts of interest to disclose.
: Ethics board approval was not required for the current study, because only secondary data analysis of the completely anonymized data was conducted, and ethical approval is not mandatory for general surveys in Germany when anonymized data are analyzed. The German Ageing Survey meets the ethical standards delineated in the 1964 Declaration of Helsinki and its amendments.
: Written informed consent was given by all participants of the study.
