The questionnaire covered information about health, self-rated health status, medical history, health behaviours, physical functioning, lifestyle, food frequency, socioeconomic circumstances, psychosocial factors, quality of life of retired persons, and psychosocial environment at work and effort-reward imbalance.

The short examination included measurement of height, weight, trunk length, waist and hip circumference, blood pressure, lung function and cognitive function (memory, concentration and verbal skills).

A sample of venous blood was also collected.

To determine mortality, the death register developed by the Institute of Internal Medicine, which is based on data from medical death certificates, the Novosibirsk office of the State Statistical Bureau (Goscomstat) and from the population registration bureau (ZAGS) is used.

Since 2011, individual mortality records based on death certificates in Russia are not available to researchers. Alternative methods have been used to collect mortality data since 2011 but the death rate in the Russian cohort since 2011 is underestimated. Efforts are currently under way to retrospectively collect data on missing deaths.

In order to identify, confirm and validate incident non-fatal cardiovascular events, the same questionnaire is sent out every three years to identify the non-fatal cardiovascular events, which will be confirmed using discharge reports and hospital/medical records.
