Premies have more OSA

Who would've guessed someone would do such a study much less the fascinating results? It makes you think why Premies would be more at risk of OSA later on in childhood when they've caught up with their term counterparts. Does being prem predispose to adenoids? Is it retarded lower face craniofacial growth? Or some kind of local oropharyngeal neuropathy?
