BACKGROUND: Abdominal obesity, usually measured by waist circumference and waist-to-hip ratio, is more closely related to metabolic dysfunctions that are associated with cardiovascular diseases than general obesity, which is usually assessed by body mass index. The purpose of our study was to study the distribution of alleles and genotypes AGTR1, AGТ, LPL and ADRB2 among adolescents of the Kazakh population and to identify the relationship of these genes with predictors of obesity. METHODS: The study involved 184 adolescents aged 15–18 years of the Kazakh population. RESULTS: As a result of the study, it was revealed that the G allele of the rs328 polymorphism of the LPL gene reduces the risk of developing abdominal obesity compared to the C allele.The C/G genotype reduces the risk of developing abdominal obesity. We have identifi ed among the studied adolescents of the Kazakh population an increase in the ratio of waist volume (WV) to hip volume (HV) among boys, which may in the future lead to obesity and cardiovascular diseases in general. CONCLUSION: It was also found that the G allele of the rs328 polymorphism of the LPL gene reduces the risk of abdominal obesity. Therefore, in addition to determining BMI, we recommend determining the ratio WV to HP. It was found that an increase in the ratio of WV/HV by 1 cm increases the chance of developing hypoapolipoproteinemia A1. [ABSTRACT FROM AUTHOR]

Abstract This study examines the association between environmental radiation exposure and essential hypertension in a series of investigated geographical districts adjacent to the Semipalatinsk nuclear test site in Kazakhstan. The sample consists of 2000 volunteers participants in screening examinations in three administrative districts close to the nuclear test site, which was carried out as part of the Government Programs on Environmental Health Hazard. The cross-sectional study compares prevalence ratios in a population sample with long-term exposure in the low and intermediate dose range. Age-adjusted odds ratios for hypertension were found significantly increased with higher exposure groups. After accounting for main cardiovascular risk factors into the model and stratifying by gender, the prevalence odds ratios for radiation remained significantly increased, with a significant dose-response effect observed for some but not all subgroups. The results support existing evidence of cardiovascular health effects of radiation exposure and of persisting environmental health issues that require attention in both epidemiological surveys and healthcare provision. Highlights • Large territories of Kazakhstan were exposed to radiation due to nuclear tests. • Nuclear tests lead to long-term exposure of the population in the low dose range. • There is an association between environmental radiation exposure and hypertension. • Screening allows us to diagnose CVD in the irradiated people in the early stages. • Radiation health effects should be considered in health services planning.
