Compliance with ethical standards
: The authors declare no conflict of interest.
: NESDA was approved centrally by the Ethical Review Board of the VU University Medical Centre and subsequently by local review boards of each participating centre and has therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments. Written informed consent was obtained from all participants at the start of base- line assessment.
: This written informed consent asked for permission to use genetic information, to retrieve health care information from physicians, and to link respondent information to external data banks (e.g., mortality or hospitalization databases). Confidentiality of data is maintained using a unique research ID number for each respondent, which enables to identify individuals without using names. Only a limited number of persons (principal investigator, data manager) have access to the record that link ID number to identifiable information.
