THE PREVALENCE OF THE METABOLIC SYNDROME IN THE ELDERLY POPULATION IN YAKUTIA

Aim: to study the prevalence of the metabolic syndrome among the elderly and senile population of Yakutsk (including long-lived people), using different definitions of the metabolic syndrome. Material and methods. Metabolic syndrome prevalence was studied based on the representative sample of 485 individuals (210 males and 275 females), residing in Yakutsk. Results. The prevalence of MS among the population of Yakutsk aged 60 and over was 21.4% by NCEP ATP III definition (14.3% in aboriginals, 28.2% in non-aboriginals), 22.1% by AACE definition (13.9% and 29.8%, respectfully), 31.5% by AHA definition (22.8% and 39.9%, respectfully), 35.3% by IDF definition (257% and 44.4%, respectfully), 36.5% by JIS definition (28.3% and 44.4%, respectfully), and 51.5% by RSC definition (43% and 59.7%, respectfully). By all definitions, MS prevalence was 1.5 times to twice lower in aboriginal than in non-aboriginal population. Analysis of the MS prevalence (as defined by NCEP-ATP III definition) in the population of Yakutia aged 60 and over showed that alternate manifestations of MS were diagnosed more often in the presence of fasting hyperglycemia or type 2 DM. These manifestations occurred 1.5 to 2 times more often in aboriginal than in non-aboriginal population. Conclusion. The prevalence of MS among the population of Yakutsk aged 60 and over was 21.4% by NCEP ATP III definition (14.3% in aboriginals, 28.2% in non-aboriginals), 22.1% by AACE definition (13.9% and 29.8%, respectfully), 31.5% by AHA definition (22.8% and 39.9%, respectfully), 35.3% by IDF definition (257% and 44.4%, respectfully), 36.5% by JIS definition (28.3% and 44.4%, respectfully), and 51.5% by RSC definition (43% and 59.7%, respectfully). By all definitions, MS prevalence was 1.5 times to twice lower in aboriginal than in non-aboriginal population. Analysis of the MS prevalence (as defined by NCEP-ATP III definition) in the population of Yakutia aged 60 and over showed that alternate manifestations of MS were diagnosed more often in the presence of fasting hyperglycemia or type 2 DM. These manifestations occurred 1.5 to 2 times more often in aboriginal than in non- aboriginal population.
