The hypothesis for this study is that children with sleep disordered breathing will benefit from treatment with Continuous Positive Airway Pressure (CPAP) or Bi-level Positive Airway Pressure (BiPAP) in terms of reduction in cardiovascular risk markers and insulin resistance.

The CPAP machine delivers a predetermined level of pressure. It releases a stream of compressed air through a hose to the nose mask and keeps the upper airway open under continuous air pressure. This air pressure prevents obstructive sleep apnea, which occurs as a result of narrowing of the airway due to the relaxation of upper respiratory tract muscles during sleep. This machine helps to increase the oxygen flow by keeping the airway open.

The BiPAP machine delivers two levels of pressure. Inspiratory Positive Airway Pressure (IPAP) is a high amount of pressure, applied when the patient inhales and a low Expiratory Positive Airway Pressure (EPAP) during exhalation.

Further study details as provided by Mayo Clinic:

Primary Outcome Measures:
  • Change in Level of Fasting Glucose [ Time Frame: baseline, 3 months ]

Secondary Outcome Measures:
  • Change in Level of Fasting Insulin [ Time Frame: baseline, 3 months ]
  • Change in Level of Lipids [ Time Frame: baseline, 3 months ]

Enrollment: 11
Study Start Date: March 2011
Study Completion Date: January 2013
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CPAP/Bi-PAP
Subjects will be treated with either CPAP or Bi-PAP for three months.
Device: CPAP/BiPAP
Subjects will be treated with either CPAP or Bi-PAP for three months.

Detailed Description:
Obese children with Moderate to Severe Sleep Apnea will have baseline evaluation of markers of cardiometabolic risk and insulin resistance. Subjects will then use either the CPAP or BiPAP machine for 3 months and will return for another blood draw for measurement of the markers for cardiometabolic risk and insulin resistance.
