Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Insulin Resistance [ Time Frame: 20 weeks ]
    Fasting insulin concentration (uU/ml) will be measured before and after 2 hours of 75g glucose drink. Insulin resistance will be measured before and after 20 weeks of the intervention.

  2. Oral glucose test OGTT [ Time Frame: 20 weeks ]
    Fasting glucose concentration (mg/dL) will be measured before and after 2 hours of 75g glucose drink. OGTT will be measured before and after 20 weeks of the intervention. Fating glucose and fasting insulin concentrations will be combined to report HOMA-IR index (homeostatic model assessment of insulin resistance).

  3. Testosterone [ Time Frame: 20 weeks ]
    Testosterone (ng/mL) concentrations will measured at baseline and after 20 weeks of the intervention. Results of testosterone level and SHBG level will be combined to report FAI index (index of free androgen).

  4. DHEA-SO4 [ Time Frame: 20 weeks ]
    DHEA-SO4 (umol/L) concentrations will measured at baseline and after 20 weeks of the intervention. Results of testosterone level and SHBG level will be combined to report FAI index (index of free androgen).

  5. SHBG [ Time Frame: 20 weeks ]
    SHBG (nmol/L) concentrations will measured at baseline and after 20 weeks of the intervention. Results of testosterone level and SHBG level will be combined to report FAI index (index of free androgen).

  6. Free androgen index FAI [ Time Frame: 20 weeks ]
    Results of testosterone level and SHBG level will be combined to report FAI index (index of free androgen).

  7. Body weight [ Time Frame: 20 weeks ]
    Body weight (kg) will be assessment at baseline and after 20 weeks of the intervention.

  8. Body height [ Time Frame: Baseline ]
    Body height (cm) will be assessment at baseline of the intervention.

  9. Body composition [ Time Frame: 20 weeks ]
    Fat mass (%), fat free mass (%) will be assessment at baseline and after 20 weeks of the intervention.

  10. Blood lipid profile: cholesterole [ Time Frame: 20 weeks ]
    Cholesterole (mg/dL) will be measured at baseline and after 20 weeks of the intervention

  11. Blood lipid profile: triglicerydes [ Time Frame: 20 weeks ]
    Triglicerydes (mg/dL) will be measured at baseline and after 20 weeks of the intervention

  12. Blood lipid profile: high density lipoprotein [ Time Frame: 20 weeks ]
    High density lipoprotein HDL (mg/dL) will be measured at baseline and after 20 weeks of the intervention

  13. Blood lipid profile: low density lipoprotein [ Time Frame: 20 weeks ]
    Low density lipoprotein LDL (mg/dL) will be measured at baseline and after 20 weeks of the intervention


Secondary Outcome Measures :
  1. Assessment of qualitative and quantitative of the microbiome [ Time Frame: 20 weeks ]
    Qualitative and quantitative determination of the composition of gut microbiota will be assessment at baseline and after 20 weeks of the intervention

  2. Assessment of B-glucuronidase and B-glucosiadase activity [ Time Frame: 20 weeks ]
    B-glucuronidase and B-glucosiadase activity in stoolen sample will be assessment at baseline and after 20 weeks of the intervention

  3. Assessment of short-chain fatty acids [ Time Frame: 20 weeks ]
    Assessment of short-chain fatty acids will be assessment at baseline and after 20 weeks of the intervention
