Prevention and Control of MetS

 MetS Prevention and Control 

  • Abdominal obesity and hypertension and low HDL are strong predictors of MS (metabolic syndrome).1MS identifies people at high risk of diabetes and CVD who are most responsive to lifestyle changes.
  • High carbohydrate intake, (particularly high glycemic load) and low physical activity are 2 important contributors to the development of MS among Asian Indians.2-4
  • Lifestyle modifications to achieve a modest weight loss (5%-7%) in overweight individuals could reduce the prevalence of MS and its progression to diabetes. Weight loss requires attention to both energy intake and expenditure. Even small to moderate amounts of physical activity (<7 Kcal/min) is helpful in preventing MS.
  • Food items with high glycemic index (eg. refined grains and calorie-sweetened soft drinks) have an adverse effect on the development of MS, whereas modest intakes of animal and vegetable proteins, as well as healthy carbohydrates from fruits and vegetables, have a beneficial effect.5
  • Ghee, a form of clarified butter, was positively and independently associated with high blood pressure in these children.6 Ghee is very high in saturated fat and cholesterol oxide and is used liberally by affluent Indians worldwide.6
  • Progression of prediabetes to diabetes is high among Asian Indians (18%/y) but can be significantly reduced by both lifestyle modification and metformin.7 As the condition progresses, however, drug therapy directed toward the individual risk factors might be required.8
  • Pioglitazone has significantly favorable effects on HDL particle size, markers of inflammation, and adipokines, and these properties contribute to its antiatherogenic effects.9
  • Patients with CAD (coronary artery disease) and MS have higher risk of recurrent coronary events and derive incremental benefit from aggressive high-dose statin therapy.10 It seems reasonable to achieve TC/HDL goal of <4 in people with MS. The Indo US Health summit recommends LDL cholesterol < 100 mg /dL and non-HDL cholesterol <130 mg/dL for Asian Indians without CAD and diabetes. The recommended goal is LDL cholesterol <70 mg/dL and non-HDL cholesterol <100 mg dL for Asian Indians with diabetes or CAD.11 This is by far the simplest and most effective recommendation and is in agreement with the current literature.12
  • In people with MS, controlling abnormal lipid levels and hypertension to normal levels may prevent up to 50% of major acute coronary events; more importantly, controlling to optimal levels may decrease these events by 80% or more.13
  • Low fruit and vegetable consumption and high sweetened beverage consumption are independently associated with the prevalence of MS.14 
  • Compared with serving low-sugar cereals, high-sugar cereals increase children’s total sugar consumption and reduce the overall nutritional quality of their breakfast. Children will consume low-sugar cereals when offered, and they provide a superior breakfast option.15
