    • "In spite of variations in criteria and thresholds, all definitions agree that the MetS is a cluster of metabolic factors predictive of cardiovascular disease (CVD) risk, and include obesity , high blood pressure, dyslipidemia, and hyperglycemia. Studies have shown that the presence of the MetS adds to the risk of CVD and diabetes (Ford 2005; Grundy 2006; Kurl et al. 2006; Sundström et al. 2006; Lorenzo et al. 2007), although its clinical value is still questioned (Kahn et al. 2005; Reaven 2005), regardless of its epidemiological interest . Both NCEP and IDF definitions may be particularly useful for epidemiological purposes, since they do not require the assessment of insulin resistance. "

    ABSTRACT: According to two current definitions, the prevalence of the metabolic syndrome (MetS) among black Haitians of Montreal was <20%, 30%-36% in Algonquin Indians of Quebec, and >45% in Mexicans of Oaxaca (all aged 35-60 y). Although phenotypes were different, high triglycerides and fasting dysglycemia were good predictors of MetS in all three groups using both definitions. The international cut-offs for abdominal obesity were not predictive of MetS in the Haitian subjects.

    • "Metabolic syndrome diagnosis has been proposed as being clinically useful to identify patients who are at a higher lifetime risk of both CVD and type 2 diabetes and reinforcing lifestyle modification within a multiple risk factor therapeutic strategy (Grundy, 2006b). Indeed, Grundy (2006a) restates that the primary reason why the NCEP ATP III introduced the metabolic syndrome into its clinical guidelines was to emphasize the importance of lifestyle therapy in clinical practice (Grundy, 2006a).

    ABSTRACT: We examined the single and combined effects of a 1-year diet and exercise intervention on the International Diabetes Federation (IDF) metabolic syndrome among middle-aged males. The study was a randomized, controlled, 2 x 2 factorial intervention study. Participants included 137 men with metabolic syndrome according to the IDF criteria aged 40-49 years randomly allocated to four intervention groups: diet alone (n=34), exercise alone (n=34), the combination of the diet and exercise intervention (n=43) or control (n=26). The main outcome measure was metabolic syndrome as defined by IDF criteria (2005). In the combined diet and exercise group, 14 participants (32.6%) (P<0.0001 as compared with control) had the metabolic syndrome after 1-year intervention. In the diet-only group, 22 participants (64.7%) (P=0.023 vs control) and in the exercise-only group 26 participants (76.5%) (P=0.23 vs control) had the metabolic syndrome following the intervention. Utilizing the factorial design, both dietary and exercise intervention had significant effects (P<0.005) on the resolution of the metabolic syndrome. Both exercise and dietary intervention reduced metabolic syndrome prevalence compared with control after 1 year of intervention. However, the combined diet and exercise intervention was significantly more effective than diet or exercise alone in the treatment of the metabolic syndrome.
