Participants underwent comprehensive clinical measurements, including polysomnography, a gold-standard sleep study that records brain waves, oxygen levels, heart rate, and breathing patterns during sleep. Analysis revealed several key predictors that significantly correlated with the presence and severity of obstructive sleep apnoea. This finding underscores the importance of a biopsychosocial model in understanding sleep apnoea in morbid obesity.
