Changes in Cardiovascular Risk Factors in Residents of the Siberian Region (According to Epidemiological Studies)

Abstract

Aim. To analyze prevalence of cardiovascular risk factors in the Kemerovo region based on the results of epidemiological studies (2013 and 2016).Material and methods. The study was based on two large epidemiological studies of the Kemerovo region: on 2013, «The epidemiology of cardiovascular diseases and their risk factors in the Russian Federation» and on 2016, «The prospective study of urban and rural epidemiology: study of the influence of social factors on chronic non-infectious diseases in low, middle and high income countries». In the study we analyzed cardiovascular risk factors using identical questionnaires, functional, anthropometric, biochemical means and measured on identical scales. As a result, we analyzed the prevalence of smoking, diabetes mellitus, overweight and obesity, abdominal obesity, hypercholesterolemia and hypertriglyceridemia, high levels of low-density lipoprotein (LDL).Results. Univariate analysis indicates that in the sample of 2016, compared to the sample of 2013, the prevalence of smoking is statistically significantly lower, as well as the proportion of participants with high cholesterol levels, but not taking lipid-lowering drugs. In contrast, the prevalence of diabetes, hypercholesterolemia and hypertriglyceridemia is higher. In women, the frequency of abdominal obesity on 2016 is lower than on 2013: at 35-44 age group odds ratio (OR) =0.67 with 95% confidence interval (CI) 0.44-1.03, at 45-54 age group OR =0.47 with 95% CI 0.31-0.72, 55-65 age group OR =0.49 with 95% CI 0.30-0.79. A high incidence of diabetes, hypercholesterolemia and hypertriglyceridemia is characteristic mainly of older women (55-65 age group): accordingly, OR =1.96 with 95% CI 1.19-3.22, OR =1.42 with 95% CI 1,02-1.97, OR =1.51 at 95% CI 1.08-2.12. In the 45-54 age group of men, they smoked statistically significantly less often on 2016 compared to 2013, OR =0.59 with 95% CI 0.36-0.96. The prevalence of overweight and obesity in both samples is the same: for women, the OR for overweight in different age groups is within 0.74-0.87, for men - within 0.95-1.78; for obesity OR in women is from 0.70 to 0.79, in men - from 1.03 to 1.34.Conclusion. A significant advantage of the study is the analysis of changes in prevalence in age and gender groups, which showed significant differences in the dynamics of men and women in different age categories for a number of risk factors. Analysis of the dynamics of the prevalence of cardiovascular risk factors makes it possible to assess the effectiveness of state and regional policies in the field of health protection and, first of all, "risk groups” that require closer attention, development and implementation of targeted health-saving technologies.

Prevalence of smoking and its changes over time in Russia: data from the ESSE-RF study

“…У женщин наблюдается более сложная динамика увеличения распространенности курения с 12% в середине 90-х гг до 18-19% в 2000-2010гг и последующее снижение до 17,5% к 2016г. При сопоставлении распространенности курения в двух эпидемиологических исследованиях сибирского региона в 2013 и 2016гг также показано снижение распространенности курения у мужчин, при отсутствии динамики у женщин [9].…”
