Health Update Surveys

Health Update Surveys

Every two to three years, surveys are sent to LTFU study participants asking them to update their health histories. There are usually three options for completing a survey.

Option 1 - By Mail

Participants can complete the paper version of the survey and return it in the prepaid, self-addressed envelope. If you have received a paper version of the survey but have lost it and would prefer to complete the survey using this option, please call the toll-free number below to request another survey be sent to you.

Option 2 - By Interviewer

Participants can complete the survey via the telephone with one of the Long-Term Follow-Up Study telephone interviewers by calling 901-595-6600 or toll-free at 1-800-775-2167. The telephone survey staff is available to conduct surveys during the following hours: Mon-Thurs 8:30 a.m. - 9:00 p.m. CST; Fri 10:30 a.m. – 7:00 p.m. CST; Sat 10:30 a.m. - 7:00 p.m. CST; and Sun 12:30 p.m. - 9:00 p.m. CST.

Option 3 - Online

Most surveys can also be completed online using a PC, tablet, or smartphone. The website address and login information are included with each survey.


For assistance in using any of these completion options, please contact the Long-Term Follow-Up Study staff toll-free at 1-800-775-2167, or email us at
