Moreover, pdf viewer is only marginally associated with waist circumference This observation was confirmed by Sophie Viewrr and colleagues, who reported that in South Asian adults the protective effects of total subcutaneous adipose tissue for T2DM and HbA 1c levels emerge only after accounting for visceral adipose tissue VAT accumulation The seminal study of Pories et al. By contrast, after adjustment for age, sex, smoking, diabetes mellitus, hypertension and waist circumference, increasing tertiles of BMI were inversely associated with risk of death HR 0.

  • The failure of BMI to fully capture cardiometabolic risk is partially related to the fact that BMI in isolation is an insufficient biomarker of abdominal adiposity.

In recent clinical investigations, functional renal denervation obtained by means of catheter-based radiofrequency or ultrasound technologies achieved BP control in patients with resistant HT [] and polycystic ovary syndrome [ ], further emphasizing the link between SNS overdrive and I.

There is growing evidence that regular and consistent programmes of exercise will reduce abdominal fat deposits significantly, independent of weight loss [ 1011 ].

  • Nguyen-Duy, T.

  • Sympathetic activation can be triggered by reflex mechanisms as arterial baroreceptor impairment, by metabolic factors as insulin resistance, and by dysregulated adipokine production and secretion from visceral fat with a mainly permissive role of leptin and antagonist role of adiponectin.

  • Such patients have metaboic high incidence of severe insulin resistance, diabetes, dyslipidaemia, hepatic steatosis and polycystic ovary syndrome in females 46 which are mostly reversed by treatment with leptin. Like carbohydrate, it may be the type of fats that are consumed, rather than the total amount, that has a greater effect on components of the MetS.

Landmark studies from the Bogalusa Heart Study demonstrated that cardiovascular risk factors present in childhood are predictive of coronary artery disease in adulthood 68 ,

Stump, S. Interestingly, chronic SNS weight loss surgery still obese contributes to a further decline of insulin sensitivity. Whether the effects of the MetS are due to a sum of comorbidities or to individual features is still a matter of debate; however, there is sufficient data to support an increased risk of CVD in people affected by the MetS in the absence of other baseline risk factors [ 8 — 10 ]. Tesauro, M. Rahmouni, M. InLandsberg suggested that sympathetic activation could represent an insulin-mediated adaptative response to overeating promoting thermogenesis and acting as a buffer against weight gain [ 34 ].

Prevalence of the MetS among U. The contributing factors are complex, a central feature is unresponsiveness to insulin at the cellular level because of changes in receptor binding or post-receptor mechanisms. Combination therapy of fibrates plus statins in high-risk individuals attains the target for non-HDL-C better than statins alone.

For children between the ages of obeaity and 10 yr, they suggested that the MetS not be diagnosed but that a strong message regarding weight reduction should be made in those with abdominal obesity.
