Prevalence of Metabolic Syndrome (METS) using IDF 2005 Guidelines in a Semi Urban South Indian (Boloor Diabetes Study) Population of Mangalore

摘要

Objective : To identify metabolic syndrome (MetS) prevalence using International Diabetes Federation (IDF) 2005 guidelines in a semi urban south Indian (Boloor Diabetes Study) population of Mangalore. Methods : Population of randomly selected adults ≥20 years living in Boloor locality who were available for the house to house survey were assessed for the following: anthropometric variables; blood pressure; fasting blood glucose and lipid profile. Among 800 responders; 300 men, 500 women, 551 were examined (68.8%). Fasting plasma glucose as well fasting lipid profile could be done for 451 (147 men, 304 women) 81.85%; Data was analysed for prevalence of MetS and its individual components. Diagnosis of MetS was based on IDF 2005 criteria for Asian men and women. Intergroup comparisons were performed using student ‘t’ test and Chi-square test. Results : MetS was prevalent in 134 of 451(29.7%); men 39 (26.5%) and women 95 (31.2%). Prevalence of individual components of MetS were as follows: increased waist circumference, (common component) present in all; elevated TG in 38.8%; low HDL-C in 59.7%; increased FPG in 57.4%; elevated SBP in 80.5% and DBP in 56.7%; body mass index (BMI) ≥ 25 kg/sq.m (obesity) in 58.9% Barring increased waist circumference which is the essential criteria for diagnosis of Mets, Systolic hypertension emerged as the most frequent component in the population followed by low HDL-C and elevated FPG. Elevated TG was less prevalent in this population. Conclusion : Prevalence of MetS in this semi urban population (Boloor) of Mangalore compares with MetS prevalence identified in cross sectional studies in India. Prevention and treatment of the predictive factors: dyslipidemias, hyperglycaemia, hypertension, together with enhanced physical activity may together reduce the prevalence of MetS.
