Among Shors, the following factors increased AH risk: female sex, age, hypercholesterolemia, hyperbetacholesterinemia, hypertriglyceridemia, obesity (including transabdominal obesity), glucose intolerance, and the DD ACE, CT MTHFR, and AA ADRB1 genotypes; among the non-indigenous population, the main factors were age, hypercholesterolemia, hyperbetacholesterinemia, hypoalfacholesterinemia, hypertriglyceridemia, obesity (including transabdominal obesity), and ID ACE genotype.
Background: To study the genetic forms and pathophysiology of arterial hypertension by evaluating plasma renin activity in the Shors, minor indigenous peoples inhabiting the south of Western Siberia. Methods: A single-stage study of indigenous (the Shors) and non-indigenous peoples living in the villages of Gornaya Shoria of the Kemerovo region in the south of Western Siberia was conducted in the period from 2013 to 2017. One thousand four hundred nine adults (901 Shors and 508 non-indigenous inhabitants) were recruited in the study using a continuous sampling plan. Arterial blood pressure was measured according to 2018 ESC/ESH guidelines for the management of arterial hypertension. All the respondents underwent clinical and instrumental examination. Plasma renin activity was determined by enzyme-linked immunoassay with the BRG kits (Germany). Polymorphisms of ACE (I/D, rs 4340), АGT (c.803 T > C, rs699), AGTR1 (А1166С, rs5186), ADRB1 (с.145A > G, Ser49Gly, rs1801252) and ADRA2B (I/D, rs 28,365,031) genes were tested using polymerase chain reaction. Results: Renin-dependent hypertensive patients prevailed in both ethnic groups (65.6% in the indigenous group vs. 89.8% in the non-indigenous group, p = 0.001). Prevalence of a volume-dependent AH was low in both groups (34.4% in the indigenous group vs. 10.2% in the non-indigenous group, р = 0.001). The D/D and Т/Т genotypes of the АСЕ [OR = 6.97; 95% CI (1.07-55.58)] and AGT [OR = 3.53; 95% CI (1.02-12.91)] genes were associated with the renin-dependent AH in the Shors. The C/C genotype of AGTR1 gene was found to predispose to the volumedependent AH [OR = 5.25; 95% CI (1.03-27.89)]. The C/C genotype of AGTR1 gene was associated with moderate or high renin levels suggesting essential AH in the non-indigenous group [OR = 5.00; 95% CI (1.21-22.30), р = 0.029]. Conclusion: An in-depth understanding of AH pathophysiology and its genetic forms ensures the optimal choice of blood pressure-lowering treatment and optimizes AH control.

Adverse prognostic ACE DD, ADRB1 AA, MTHFR TT, and eNOS 4a/4a genotypes were more frequently observed in the non-indigenous ethnic groups; the ADRA2B DD genotype was more common in the native population. Hypertension was associated with the ACE DD, МTHFR CT, and ADRB1 AA genotypes in the native ethnic group and with the ACE ID genotype in the non-indigenous population.
An analysis of the age features of the prevalence of arterial hypertension in basic professional groups of the coal mining enterprises has been carried out. A total of 1575 workers of coal mines and pits of the Kuzbass united into nine professional groups participated in the research. The results of the study dem onstrated the distinctions of the age structure in professional groups, which is evidence of the expressed pro fessional senescence among workers of mines, which manifests in a decrease in the relative density of individ uals over the age of 50. In groups with expressed professional senescence, a decrease in the relative density of individuals with arterial hypertension, the so called "healthy worker effect" is observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
