Efficacy outcomes:
1. Measurements and anthropometric indexes. Measurement time: at baseline, 3, 6 and, 12 months. It will measure by:
-Body Max Index-BMI (Weight/(Height*Height). The weight expressed in Kg and, the height expressed in meters)
- Hip circumference (Value expressed in cm)
- Waist-hip Index (Waist circumference/Hip circumference. All values are expressed in cm)
- Waist- Height Index (Waist circumference/Height. All values are expressed in cm
- Conicity Index (Waist circumference in cm/(0.109*square root of (weight in kg/height in cm)))
2. Glucose on an empty stomach and at two hours after an oral glucose tolerance test (Value expressed in mmol/L). Measurement time: at baseline, 6 and, 12 months.
3. Hemoglobin (Value expressed in g/L). Measurement time: at baseline, 6 and, 12 months.
4. Hemoglobina glucosilada -HbA1c (Value expressed in %). Measurement time: at baseline, 6 and, 12 months.
5. Fasting insulin (Value expressed in μU/ml). Measurement time: at baseline, 6 and, 12 months.
6. Insulin resistance indexes.
- HOMA-IR will be calculated by the homeostatic model of Mathews
- HOMA-β will be determined by the homeostatic model (HOMA) of Mathew
- QUICKI Index calculated as [1/[log insulin0 + log glucose0]
- Bennett Index calculated as [40/insulin0]
- Raynaud Index calculated as 1/(log insulin0 x log glucose0)
7. Biochemistry test (Triglycerides, Cholesterol, HDL-c, LDL-c, TGP; TGO, GGT, Uric acid, Creatinine in μmol/L). Measurement time: at baseline, 6 and, 12 months.
8. Blood Pressure (Systolic and Diastolic blood pressure expressed in mmHg).Measurement time: at baseline, 3, 6, 9 and, 12 months.
Safety outcomes:
9. Adverse Events-AE. Measurement time: at baseline, 1 ½ month (6 weeks), 3 months, 4 ½ months (20 weeks), 6 months, 9 months and, 12 months.
- Occurrence of some AE in the subject (Yes, No).
-Type of AE (description of EA using the Common Terminology Criteria for Adverse Events (CTCAE), version 4.0)
- Intensity of the AE (Light, Moderate, Severe according to 45/2007 CECMED regulation)
- Seriousness of the AE (Serious, Not serious)
- Duration of the AE (Time from event start until stop the event)
- Attitude regarding the treatment under study (No changes, Dose modification, Treatment temporary interruption, Treatment definitive interruption)
- Result of the AE (Recovered, Improved, Persists, Squeals)
- Causality relationship (Very likely, Probable, Possible, Unlikely, Not related, Not evaluable)
-Treatment indicated for the AE (Specify the treatment for every AE)
