MESA Follow-Up
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.
