Metabolic syndrome in the inhabitants of Mountain Shoria: prevalence, variants of manifestations and ethnic peculiarities

Background. Metabolic syndrome is one of the most dangerous risk factors of cardiovascular and endocrine diseases development and mortality due to them, especially among young people. Aims: Our purpose was to study the prevalence of the metabolic syndrome, combinations of its components in indigenous and non-indigenous inhabitants of Mountain Shoria. Materials and methods. During the period since 2012 to 2015 we have examined the inhabitants of the villages of Mountain Shoria: Ust-Kabyrza, Orton, Sheregesh by a continuous method on the basis of a name list. All the participants were examined by a cardiologist, an endocrinologist and a general practitioner, also a waist circumference and arterial blood pressure were measured. Specific diagnostic methods included an estimation of blood glucose level, triglycerides (TG) and high density lipoprotein cholesterol (HDL-C) in blood serum. Results. All the subjects (460 persons) were divided into age (18–39 years, 40–59 years, 60 years and older), ethnic (the Shors and the non-Shors) and gender (men and women) groups. Generally, the metabolic syndrome was diagnosed in 40.2% of inhabitants of Mountain Shoria. Metabolic syndrome (MS) was presented in 12.4% of indigenous men and in 47.8% of non-indigenous examined men (р=0.00001). MSwasrevealedin 36.8%, of Shor-women and in 60.7% of non-Shor women (р=0.00002). The most common variant of 3-component MS was abdominal obesity + arterial hypertension + hyperglycemia and the rarest was – abdominal obesity + TG + hyperglycemia. The most common variant of 4-component MS was a combination of abdominal obesity + hyperglycemia + arterial hypertension + HDL-C, the rarest was abdominal obesity + arterial hypertension + TG + HDL-C. Different variants of 3-component and 4-component MS occurred with similar frequency in all age groups of the Shors and non-Shors. Conclusions. Generally MSoccurred more frequently in non-indigenous inhabitants than in indigenous inhabitants. Only in women of young age group this pathology was revealed with the similar frequency among both ethnic groups. Among all the inhabitants of Mountain Shoria the most frequent clinical variant of 3-component MS was a combination of abdominal obesity + arterial hypertension + hyperglycemia and of 4-component variant – a combination of abdominal obesity + hyperglycemia + arterial hypertension + HDL-C
