Population cohort
Follow Up
The follow-up phase commenced in June 2013. Each participant was given a health diary to fill up and return to the TMC office every 6 months. This was to record all illnesses, visits to health facilities, medications and procedures, cost of each treatment and source of payment. Due to the low percentage of the return of these self-report forms, we decided to set up a team to call each participant every 6 months and interviewed them based on the health diary. A comprehensive follow-up is targeted every 5 years, where each participant will again be interviewed, biophysical measurements repeated and biospecimens collected. The National Registration Department (NRD) provided the mortality data and the cause of death every 6 months.
