Primary Outcome Measures:
  • Change in bone mineral density and body composition [ Time Frame: Baseline and 6 months ]
    Bone mineral density and body composition by dual-energy X-ray absorptiometry (DXA)

  • Change in fasting and postprandial glucose [ Time Frame: Baseline and 6 months ]
  • Change in Pulmonary function tests [ Time Frame: Baseline and 6 months ]
    Pulmonary function tests consiste of spirometry, body plethysmograph, diffusing capacity for carbon monoxide (DLco), and respiratory muscle strength. Measurements are conducted using the Collins Plus Pulmonary Function Testing Systems (Warren E. Collins, Inc., Braintree, MA, USA).

  • Change in bone microarchitecture [ Time Frame: Baseline and 6 months ]
    Bone microarchitecture by high-resolution peripheral quantitative computed tomography

  • Change in lipid profile [ Time Frame: Baseline and 6 months ]
    Total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol
