title: Metabolic syndrome components and prevalence of cardiovascular disease among type 2 diabetic patients in Malaysia.
abstract: Metabolic syndrome (MetS) is common among patients with type 2 diabetes mellitus (T2DM) and increases the risk of cardiovascular disease (CVD) and all-cause mortality. The objective of this study was to investigate the association between the components of MetS and the prevalence of CVD among patients with T2DM. We studied 313 patients aged > or = 30 years diagnosed with T2DM at two tertiary care hospitals. Patients were recruited by systematic random sampling. Clinical data was obtained using an interviewer-administered structured questionnaire and from a review of their medical records. MetS was diagnosed using NCEP ATP III, WHO, IDF and the new Harmonized definitions. Specific MetS components such as BMI, waist circumference, waist-to-hip ratio, hypertension, HDL-C and triglyceride levels were evaluated to determine if they had an association with CVD. Thirty-six point one percent of the subjects had CVD. The mean age of the subjects was 55.7 +/- 9.2 years and the mean duration of having diabetes was 10.1 +/- 8.1 years. The overall prevalences of MetS (> or = 3 of 5 components) (95% CI) were 96.1% (94.0-98.3), 95.8% (93.6-98.1), 84.8% (80.8-88.9) and 97.7% (96.1-99.4) using NCEP ATP III, WHO, IDF and Harmonized definitions, respectively. Patients with MetS had a higher prevalence of CVD using NCEP ATP III (98.2% vs 93.5%), WHO (98.2% vs 93.0%), IDF (87.6% vs 82.0%) and Harmonized criteria (98.2% vs 96.0%). The greater the number of MetS components, the greater the chance of having CVD using three definitions for diagnosing MetS: WHO, IDF and Harmonized (p < 0.05). MetS and the combination of the individual components of MetS were significantly associated with CVD among type 2 diabetic patients in Malaysia. Aggressive treatment of MetS components is required to reduce cardiovascular risk in T2DM.
