Higher awakening threshold of preterm infants in prone position may be a risk factor for SIDS.

Aim: The supine sleeping position in the prevention of sudden infant death syndrome in preterm infants is poorly understood. We aimed to investigate the effect of sleep posture on cardiorespiratory parameters and movement patterns in preterm infants close to discharge.

Methods: This observational study included neonates born in 2022 at the University Hospital Schleswig-Holstein, Lübeck, Germany.
