Outcome Measures

Primary Outcomes (1)

  • Improvement in the apnea-hypopnea index/hour: Sleep study: Standard polysomnography

    Assess whether a lifestyle change program can be effective in the medium and long term for the treatment of OSAS in obese patients with OSAS who are already receiving CPAP treatment.

    Baseline, at 3 months and 12 months.

Secondary Outcomes (48)

  • waist circumference (above the upper iliac crest): centimetre

    Baseline, at 3 months and 12 months.

  • neck circumfarence: centimetre

    Baseline, at 3 months and 12 months.

  • waist to hip ratio

    Baseline, at 3 months and 12 months.

  • Measurement of visceral fat (square centimetre) by an abdominal computerized tomography (CT) scan

    Baseline, at 12 months.

  • Carotid intima-media (C-IMT) thickness (millimeter (mm)) by ultrasound of the supra-aortic vessels, using B-mode ultrasound

    Baseline, at 3 months and 12 months.

  • +43 more secondary outcomes
