ABSTRACT

Introduction: A clustering of insulin resistance, hypertension and dyslipidemia has been labeled as the metabolic syndrome by the World Health Organizations and it often develops into type 2 diabetes with premature cardiovascular disease, resulting in an increasingly heavy burden on health care systems and general decrease in quality of life[10]. Asians have a lower frequency of obesity than Caucasians, but have an increasing tendency toward metabolic syndrome [11]. Most data on MS are based on studies from Western countries with only limited information derived from Asians populations. Aim. To compare application of the metabolic syndrome (MS) 3 definitions, proposed by International Diabetes Federation (IDF) in 2005[7], Adult Treatment Panel III (NCEP-ATPIII) in 2004[8], and VNOK in 2009[4], for railways workers in MongoliaMaterials and Methods. Weare conducted study of individuals aged 18-63 years in workplace settings in 7 cities Mongolia. We are selected a total of 1272 workers of railways company in Mongolia. (737 men and 540 women) We analyzed the health data for MS based Third Report of the National Cholesterol Educational Program Expert Panel on Detection, evaluation and Treatment of high blood cholesterol in adults (ATPIII)definition, and 2 definitions by IDF(2005) and VNOK(2009) Subjects were seemed to have metabolic syndrome if they had three or more of the following 5 criteria;1.visceral obesity, waist circumference ≥ 90 cm for men, ≥80 cm for women 2.hypertriglyceridemia, ≥150 mg/dl 3.Low HDL-C, < 40mg/dl for men and,<50md/dl for women 4 high blood pressure, ≥130/85 mm Hg;and 5. High fasting glucose ≥110 mg/dl.Results. To study metabolic syndrome (MS) and its components prevalence in urban population of men and women 20–63 years old the representative sample of 1272 central and 6 citizens (737men and 540 women) has been investigated during the period from 2011 till 2012. Prevalence of MS according to NCEP-ATPIII, 2004 criteria was 27.7 % (31.3% in men and 25.1% in women). Maximum prevalence was registered according to IDF (2005) criteria- 35.8 % (35.4% in men, 36.1% in women). VNOK (2009) criteria–30.3 % (31.7% and 29.3% respectively). Subjects with high fasting glucose levels (≥5,6mmol/l) have 25.4%Conclusions. As survey indicates Metabolic syndrome is increasingly observed in elderly people, with 50,1% in the people aged 50 and over. Maximum prevalence was registered according to IDF (2005) criteria-35,8%.3 or more criteria was -47,3%.
