These participants of the cohort have been invited to a re-examination (excluding those who emigrated, actively withdrew from the study or died).
Total number of Doetinchem participants in recontact 1: 4651. The response rate is approx. 75%.

Amsterdam and Maastricht (AM)
These participants have been recontacted by a Questionnaire.
Total number of Amsterdam & Maastricht participants in recontact 1: 10202. The response rate is approx. 66%.

Future recontacts

Re-assessement by questionnaire of participants in Amsterdam and Maastricht has been completed in 2011, a complete re-examination in Doetinchem in 2012, and a next round of follow-up is being planned in 2013 in all 3 centers.

Other follow-up

LMR, LKR, CBS and validation of cases of T2D, Parkinson, Inflammatory Bowel diseases, and in 2012 Rheumatoid Arthritis

It is anticipated that in many cohorts various follow-up end-points are measured during re-contact of the subjects. The availability of such follow-up data are covered above. In this section you should describe here any other means of follow-up, such as linkage to routine registers or review of hospital records for potential end-point events suggested by the re-contacts.

Follow-up period

Describe here the follow-up period. E.g. "10 years from the baseline examination" or "Up to the end of year 2008".

Sources of data

List here the sources of information on which the follow-up was based. E.g. "Death certificates obtained from ....", "Regional computerized hospital discharge register, which covers....", "Re-contact questionnaire".

Follow-up procedure

Describe here the follow-up procedure. E.g. "Record linkage to the national Causes of Death Register, using the unique personal identification code in use in the country", "Hospital records of the persons who indicated hospitalizations in the re-examination interview were scrutinized". The Description usually requires several sentences and, depending on the procedure, may include the specification of lengthy algorithm.

End-points covered through the follow-up

  • All deaths:
    • Specification of the cause:
  • Non-fatal cancers:
    • Cancer survival:
  • Non-fatal acute coronary events:
  • Non-fatal stroke:
  • Non-fatal diabetes:
  • Fractures:
  • Cognitive impairment/dementia:
  • Nursing home admission:

ICD-version used for classification of diseases in the data

  • Which version was used (if several, specify years and/or data sources for each):
