Metabolic syndrome in the Philippine general population: prevalence and risk for atherosclerotic cardiovascular disease and diabetes mellitus

Abstract

The objectives of this study were to determine the prevalence of metabolic syndrome (MS) and its component risk factors among Filipinos using three sets of criteria and to evaluate the association between MS and atherosclerotic cardiovascular disease and diabetes mellitus. The study utilised a multi-staged cluster sampling design. The prevalence of MS was found to be 11.9% by National Cholesterol Education Program/Adult Treatment Panel (NCEP/ATP III) criteria, 14.5% by International Diabetes Federation (IDF) criteria and 18.6% by NCEP/ATP III criteria modified by the American Heart Association/National Heart, Lung and Blood Institute (NCEP/ATP III-AHA/NHLBI) criteria. Low levels of high-density lipoprotein cholesterol (HDL-C) occurred in 60.2% of men and 80.9% of women. Abdominal obesity was noted in 17.7% of men and 35.1% of women. Blood pressure (BP) ≥ 130/85 mmHg was seen in 33.3%, hypertriglyceridaemia in 20.6% and fasting blood sugar ≥ 100 mg/dL (5.55 mmol/L) in 7.1%. Age-adjusted odds ratios showed that MS, by all three definitions, predisposed an individual to diabetes mellitus (DM) and stroke while MS by the IDF definition predisposed an individual to myocardial infarction (MI). Individuals with MS did not have a significant predisposition to angina and peripheral artery disease (PAD). Thus, the metabolic syndrome is common in Filipinos, with low HDL-C as the most prevalent component. The metabolic syndrome predisposes to diabetes mellitus and stroke, with a tendency to MI using the IDF criteria.
