Psychosocial factors, including educational level, play an important role in the risk development of the general and cardiovascular mortality.
PURPOSE OF THE STUDY
To study the influence of education level on the risk development of general and cardiovascular mortality based on the results of a 27-year prospective cohort study.
MATERIAL AND METHODS
The study was carried out among the unorganized population of Tomsk in three stages: 1998—1991. — Primary examination of the cohort (1546 people aged 20-59); 2002-2005 — re-examination of the cohort; 2015 — study of mortality rates, assessment of the impact of education level on the risk of death from cardiovascular diseases (CVD) and from all causes. The following groups are distinguished: 1st — persons with higher education; 2nd — with secondary education; 3rd — with education below secondary.
RESULTS
The age-standardized relative risk (RR) of total mortality in persons with less than secondary education was 1.83, in persons with secondary education — 1.3 (in comparison with those with higher education). Relative risk of death from CVD for those with secondary and lower secondary education levels were 2.3 and 2.8, respectively. In those surveyed with education below the average RR of total mortality by 1.8 times, cardiovascular mortality — 1.6 times higher than in those with secondary education. The level of education to a greater extent influenced the formation of the risk of overall mortality in the male part of the cohort. The share of deaths from CVD among those with higher education is 30.8%, in the group with secondary education — 53.2%, in the group with lower secondary education — 68.3%.
CONCLUSION
It was found that the highest RR of total and cardiovascular mortality is observed in persons with a level of education below secondary, the lowest — in persons with higher education. In the structure of total mortality, the largest share of CVD was observed among people with lower secondary education. In men, a more significant influence of the level of education on the formation of the risk of general mortality was revealed.
