Prospective Study of the Impact of Systemic Corticosteroid Use on Measures of Sleep Disordered Breathing
Weight gain is both a significant risk factor for obstructive sleep apnea and a side-effect of long-term systemic steroids therapy.
This study aimed to investigate the impact of long-term systemic steroid treatment on sleep apnea.

The polysomnography (PSG) (Alice 3 System; Healthdyne, Atlanta, GA) consisted of continuous polygraphic recording from surface leads for electroencephalography, electrooculography, electromyography, electrocardiography, thermistors for nasal and oral airflow, thoracic and abdominal impedance belts for respiratory effort, pulse oximeter for oxyhemoglobin level, tracheal microphone for snoring, and sensors for leg and sleep position
