Studies have suggested preterm birth, defined as gestational age (GA) <37 weeks, is a risk factor for obstructive sleep apnea (OSA) in later childhood. However, little is known about the characteristics, severity, and degree of intervention of childhood OSA in former preterm infants compared to term infants. This study compares polysomnographic characteristics and surgical interventions in former preterm and term infants presenting with sleep disordered breathing.Retrospective cohort study from 2015 to 2019 at a single tertiary referral center.Electronic Medical Records of pediatric patients ages 0 to 18 presenting with sleep disordered breathing were reviewed for gestational age, polysomnographic findings, clinical characteristics, and OSA surgical interventions. Association between gestational age, polysomnographic characteristics, and surgical interventions for OSA were reported.A total of 615 patient records were analyzed. Adjusting for covariates, prematurity was associated with a 2.97× higher likelihood of development of severe OSA (aOR (95%CI): 2.97 (1.40-6.32)), increased apneic-hypoxic index (AHI) (mean (SD): 6.5 (9.8) vs. 4.6 (6.4), P
