We analyzed all-cause and coronary mortality data of the Turkish Adult Risk Factor Study cohort in Marmara and Central Anatolia regions, surveyed in 2011, and overall performance of long-term (21 years) follow-up of participants.

A total of 1,588 participants with an age range of 45 to 74 years were surveyed. Information on the mode of death was obtained from first-degree relatives and/or personnel of local health offices. Information on survivors was obtained from history, physical examination, and 12-lead electrocardiograms. Loss to follow-up was defined as the lack of physical examination for at least eight years.

Of the surveyed participants, 854 were examined, information on health status was obtained in 606 subjects, 46 individuals (28 men, 18 women) were ascertained to have died, and 82 subjects were lost to follow-up. A total of 2,800 person-years were added to follow-up. Nineteen deaths were attributed to coronary heart disease (CHD) and five deaths to cerebrovascular events. Overall mortality was estimated as 10.9 per 1000 person-years. In the age bracket of 45-74 years, overall annual all-cause mortality and CHD mortality were 12.8 and 5.5 per mille, respectively. Based on the total loss to follow-up (31.2%) during the past two decades, an annual loss to follow-up may be derived as 19.3 for every 1000 participants. This loss was nearly twice as high in participants living in big cities compared to those in smaller towns and rural areas.

A trend to slight reduction in coronary mortality, though not in overall mortality, before the age 75 years is noted in Turks. Annual loss to follow-up amounts to 2% of the participants.
