The clustering of risk factors predisposing an individual to cardiovascular morbidity and mortality are usually referred to as the ‘metabolic syndrome’ (MS). Several definitions exist, causing confusion to practicing clinicians. A consensus definition was reached by several major organizations stating that the presence of any three of five risk factors (abdominal obesity, elevated triglyceride, reduced high-density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose) constitutes a diagnosis. Cutoff points for each of the risk factors were defined, taking into account ethnicity in case of abdominal obesity. The prevalence of MS has been reported to be on the rise globally, and was mainly attributed to changes in diet and lifestyle, in addition to genetic factors and metabolic susceptibility. The risk of cardiovascular disease (CVD) has almost doubled and the risk of developing type 2 diabetes mellitus (T2DM) has increased fivefold in individuals diagnosed with MS. The prevalence T2DM in Saudi Arabia is increasing, making it an epidemic health hazard. Intervention programs to decrease the risk of progression from MS to full T2DM, and later CVD have been successful in many countries. Therefore, diagnosing MS is important to address risk factors and to prevent progression to the more serious chronic conditions. The prevalence of MS in Saudi adults varies from 16% to 40% depending on the definition used and the study location. Use of the consensus definition might decrease the number of missed cases. However, in the absence of local cutoff points for various risk factors for MS, the use of ratios such as waist/hip ratio and low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio, and family history of diabetes and CVD might aid diagnosis. Priority should be given to establishing national normal ranges, screening programs for hyperglycemia and hypertension, and community-directed programs to combat obesity and inactivity.
