Comprehensive assessment of cardiovascular risk factors of arterial hypertension in indigenous and non-indigenous inhabitants of Mountain Shoria

Abstract

Purpose: a comprehensive assessment of risk factors and a population risk of arterial hypertension (AH), which is conditioned by them, among indigenous and non-indigenous population of Mountain Shoria. Materials and methods. We conducted a clinical and epidemiological study of the population who live compactly in the areas of Mountain Shoria (Orton and Ust-Kabyrza villages) and in the urban-type village (Sheregesh). These regions of middle mountains are situated in the south of Western Siberia. We examined 1178 inhabitants of the indicated villages by a continuous method, the sampling consisted of adult population (18 years and older). For the estimation of the population risk of AH, conditioned by cardiovascular risk factors, we calculated a load by these factors, consisting of the ratio of the prevalence of these factors in the studied subpopulations to the prevalence in the entire cohort. Results. Among the studied risk factors the greatest contribution to the prevalence of AH in the entire sample has the abdominal obesity - 100 c.u., obesity - 77 c.u., elevated low-density lipoprotein cholesterol - 73 c.u., carbohydrate metabolism disorders - 59 c.u., elevated indicator of total cholesterol - 56 c.u., lack of physical activity - 54 c.u., dyslipidemia - 53 c.u. The contribution of the other risk factor is fewer, in the range from 1 to 27 c.u. The total value of the load with risk factors in the entire sample is 556 c.u. The minimum values of additional risk of AH in all age groups are registered in Shor men, the maximum values - in women of non-indigenous ethnic group. The direction of changes with age of additional risk of AH in gender groups are different: in men - a slight increase in each successive age group, in women - a pronounced increase of load in 40-64 years followed by a slight increase in the senior age group. Conclusion. The conducted study indicates the differences of population risk of AH associated with cardiovascular risk factors in the ethnic cohorts of Mountain Shoria.
