Association of Surgical Necrotizing Enterocolitis and its Timing with Retinopathy of Prematurity.

Am J Perinatol 2021 Aug 3. Epub 2021 Aug 3.

Division of Neonatology, Johns Hopkins University School of Medicine, Baltimore, Maryland.

Objective:  The study aimed to determine the association of surgical necrotizing enterocolitis (NEC) and its timing, with the development and timing of retinopathy of prematurity (ROP).

Study Design:  This was a secondary data analysis of 7,483 preterm infants from the Postnatal Growth and Retinopathy of Prematurity Study. Associations between infants with surgical NEC, early-onset surgical NEC (8-28 days), and late-onset surgical NEC (over 28 days) with ROP were evaluated by using multivariable logistic regression models, controlling for birth weight, gestational age, small for gestational age status, chronic lung disease, intraventricular hemorrhage, hydrocephalus, patent ductus arteriosus, and periventricular leukomalacia.
