≥80 cm for females
Systolic ≥130 or diastolic ≥85 mmHg
Systolic ≥130 or diastolic ≥85 mmHg or treatment of previously diagnosed hypertension
≥1.7mmol/L (≥150 mg/dL)
≥1.7mmol/l (≥150 mg/dL)or specific treatment for high triglycerides
< 1.03 mmol/L (<40 mg/dL)
< 1.03 mmol/L (<40 mg/dL) in male and 1.29 mmol/L (<50 mg/dL) in females or specific treatment for low HDL-C

5.6 mmol/l (100 mg/dL) or known T2DM
Lifestyle modification, represented by the association among regular physical exercise and a balanced diet appropriate for age, is the most important therapeutic approach in children and adolescent with obesity and risk factors for MetS . Behavioral intervention is mandatory but, in many cases, it is difficult to achieve or not sufficient and most pediatric patients require pharmacologic therapy early in their disease course. At the present time, the vast majority of drugs needed to treat insulin-resistance, hypercholesterolemia, hypertension are off-label in pediatric setting, although several studies demonstrated that pharmacological treatment for pediatric obesity and its related comorbidities are necessary .
Regarding dyslipidemia, the use of oral statins is reserved for children older than 10 years of age that, while on diet, continue to have dyslipidemia associated to family history for early cardiovascular disease (CVD) or additional risk factors.
Metformin is the only drug approved for treatment of impaired fasting glucose (IFG) or impaired glucose tolerance (IGT) in children. Several studies demonstrated its efficacy in ameliorating gluco-insulinemic profile; moreover, it has been reported a moderately effect on body weight in obese children.
Anti-hypertensive drugs, such as angiotensin-converting-enzyme inhibitors (ACEIs), angiotensin-receptor blockers (ARBs), calcium channel blockers (CCBs), and beta-blocking agents are used in pediatric patients and the choice of drug class is made on the basis of clinical characteristics of the single patient.
The core of treatment of pediatric MetS is abdominal obesity. Currently no pharmacological approach to obesity is accepted for pediatric patients. Bariatric surgery has been considered a successful treatment for MetS in obese adults in term of weight loss and decrease of mortality rate. This procedure has been used also in carefully selected obese adolescents and the outcomes seem to be similar to those for adults. However, further studies are needed to better select the patients to surgically treat and define efficacy and safety of bariatric surgery in pediatric MetS.
