description Abstract Objective To assess whether the mortality and morbidity risks vary with birth weight standard deviation score (BWSDS) in growth restricted extremely preterm infants. Study design This was a multicenter retrospective cohort study using the database of the Neonatal Research Network of Japan and including 9149 infants born between 2003 and 2010 at < 28 weeks gestation. According to the BWSDSs, the infants were classified as:

Study design This was a multicenter retrospective cohort study using the database of the Neonatal Research Network of Japan and including 9149 infants born between 2003 and 2010 at &lt; 28 weeks gestation. According to the BWSDSs, the infants were classified as: &lt;− 2.0, − 2.0 to − 1.5, − 1.5 to − 1.0, − 1.0 to − 0.5, and ≥ − 0.5. Infants with BWSDS ≥ − 0.5 were defined as non-growth restricted group. Results After adjusting for covariates, the risks of mortality and some morbidities were different among the BWSDS groups. Compared with non-growth restricted group, the adjusted odds ratio (aOR) for mortality [aOR, 1.69; 95% confidence interval (CI), 1.35–2.12] and chronic lung disease (CLD) (aOR, 1.28; 95% CI, 1.07–1.54) were higher among the infants with BWSDS − 1.5 to &lt;− 1.0. The aOR for severe retinopathy of prematurity (ROP) (aOR, 1.36; 95% CI, 1.09–1.71) and sepsis (aOR, 1.72; 95% CI, 1.32–2.24) were higher among the infants with BWSDS − 2.0 to &lt;− 1.5. The aOR for necrotizing enterocolitis (NEC) (aOR, 2.41; 95% CI, 1.64–3.55) was increased at a BWSDS &lt; − 2.0. Conclusion Being growth restricted extremely preterm infants confer additional risks for mortality and morbidities such as CLD, ROP, sepsis and NEC, and these risks may vary with BWSDS.</description><identifier>ISSN: 0378-3782</identifier><identifier>EISSN: 1872-6232</identifier><identifier>DOI: 10.1016/j.earlhumdev.2015.10.019</identifier><identifier>PMID: 26615548</identifier><language>eng</language><publisher>Ireland: Elsevier Ireland Ltd</publisher><subject>Advanced Basic Science ; Analysis of Variance ; Birth Weight ; Extremely preterm infants ; Female ; Fetal growth restriction ; Humans ; Infant ; Infant, Extremely Premature ; Infant, Newborn ; Infant, Premature, Diseases - epidemiology ; Infant, Premature, Diseases - mortality ; Japan ; Male ; Morbidity ; Mortality ; Neonatal and Perinatal Medicine ; Perinatal Mortality ; Pregnancy ; Pregnancy Complications - epidemiology ; Small for gestational age</subject><ispartof>Early human development, 2016-01, Vol.92, p.7-11</ispartof><rights>Elsevier Ireland Ltd</rights><rights>2015 Elsevier Ireland Ltd</rights><rights>Copyright © 2015 Elsevier Ireland Ltd.
