Этногенетические аспекты ожирения и нарушений углеводного обмена как факторов риска артериальной гипертензии

Abstract

Objective - to explore the association of candidate genes of arterial hypertension ACE, ADRA2B, ADRB1, MTHFR and eNOS with obesity and impaired glucose metabolism based on ethnicity. Materials and methods. Clinical and epidemiological study of compactly living population in the remote areas of the Mountain Shoria (Orton, Ust-Kabyrza, Sheregesh settlements, Kemerovo region). 1178 residents of these settlements were surveyed with the help of continuous sampling method; the sample consisted of adults (18 years and older). Results. In the group of respondents of the indigenous nationality averages Quetelet index, waist circumference and fasting blood glucose, depending on the polymorphism of candidate genes of arterial hypertension ACE, ADRA2B, ADRB1, MTHFR and eNOS were lower than in non-indigenous ethnic group surveyed. In a population of Shor was found a statistically significant relationship with the body mass index of ACE gene genotypes in a population of non-indigenous representatives - with genotypes of ADRA2B gene. In the group of indigenous ethnic group revealed the relationship from ACE gene polymorphism. Regardless of nationality, found associative connection of the indicator polymorphism of ADRA2B gene. The level of plasma glucose levels in a population of non-indigenous ethnic group was correlated with genotypes of ADRA2B gene. Conclusion. Metabolic abnormalities were detected less frequently in indigenous ethnic group compared with the non-indigenous. In Shor group ACE DD genotype and ADRA2B genes associated with obesity, the genotype 4a/4a eNOS gene - with abdominal obesity. In the group of non-indigenous ethnic group CC genotype of the MTHFR gene was associated with abdominal obesity, II genotype of ACE gene and DD ADRA2B gene - with impaired carbohydrate metabolism.
