What researchers measure

Primary outcomes

  1. Change in bone mineral density and body composition

    Bone mineral density and body composition by dual-energy X-ray absorptiometry (DXA)

    Time frame: Baseline and 6 months

  2. Change in fasting and postprandial glucose

    Time frame: Baseline and 6 months

  3. Change in Pulmonary function tests

    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).

    Time frame: Baseline and 6 months

  4. Change in bone microarchitecture

    Bone microarchitecture by high-resolution peripheral quantitative computed tomography

    Time frame: Baseline and 6 months

  5. Change in lipid profile

    Total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol

    Time frame: Baseline and 6 months
