Background: The prevalence of metabolic syndrome varies by the definition used and the population studied. In order to
make comparison among various studies possible, a new criterion which harmonizes the previous definitions was proposed.
This study aims to determine the prevalence of metabolic syndrome with the harmonized criteria, and its concordance
with the International Diabetes Federation (IDF), and National Cholesterol Education Programme-Adult Treatment
Panel (NCEP-ATP III) criteria. Methods: One hundred and two apparently healthy individuals who participated in health
screening were evaluated for metabolic syndrome. The blood pressure and anthropometric parameters were measured
according to standard protocol, and fasting plasma glucose and lipid profile were determined. Metabolic syndrome was
defined using the Harmonized, IDF and ATP III criteria. The agreement among the three diagnostic criteria was determined
with kappa statistics. Results: The prevalence of metabolic syndrome was 4.9%, 3.9% and 4.9% with harmonized,
IDF, and NCEP-ATP criteria respectively. Compared to the males, the prevalence was greater in females: Males vs
Females (harmonized, 2.2% vs 7.0%; IDF, 2.2% vs 5.3%; NCEP-ATP III, 2.2% vs 7.0%). The commonest risk factor in this
population was low HDL occurring in 93.0% and 37.8% of females and males respectively, followed by central obesity
(50.9% in females, 13.3% in males with harmonized and IDF criteria; 33.3% in females, 4.4% in males with NCEP-ATP
criteria), hypertension (12.5% in females, 18.6% in males) and hyperglycaemia (4.2% in females, 0.0% in males) in that
order. None of the participants had elevated Triglyceride. There was a substantial concordance between the harmonized
and the IDF (k=0.884) as well as the harmonized and NCEP-ATP III (k=1.000) definitions. Conclusion: The prevalence of
metabolic syndrome was low in this population. There was a substantial agreement among the three diagnostic criteria.
