Periodic follow-ups of the cohort every 6-12 months will be used to maintain contact, to correct addresses of participants, and to ascertain medical events between the examinations. At the exit interview for the first examination, participants will be asked whether they prefer to be contacted for follow-up via telephone, surface mail, or electronic mail. Follow-up contacts will be made within a month of the target.

The follow-up contacts are comprised of an appropriate mail, electronic mail, or telephone interview. Affirmative answers to preliminary queries about new medical conditions will be followed up by a telephone interview to complete an additional, more detailed questionnaire specific to the type of event which they reported. The additional questionnaire will gather information on hospitalizations, treatments and lifestyle changes recently instituted.
