Risk factors and outcomes for retinopathy of prematurity in neonatal infants with a birth weight of 1,501-2,000 g in a Chinese Neonatal Unit

ABSTRACT

To determine the risk factors and outcomes of retinopathy of prematurity [rop] in infants with a birth weight of 1,501-2,000 g. Materials and methods: clinical characteristics and risk factors were compared and nonconditional logistic regression analysis was performed to determine independent predictors for rop. There were 54 [9.8%] cases of rop in 553 patients with a birth weight of 1,501-2,000 g. The most common classification of rop was in stage 1 [50/54, 92.6%; stages 2 and 3 rop 2 infants each]. By logistic regression analysis, the following factors independently predicted rop gestational age at birth odds ratio [or] 9.01; 95% confidence interval [ci] 1.18-68.70], septicemia [or 2.88; 95% ci 1.30-6.36] and perinatal asphyxia [or 5.74; 95% ci 2.35-14.01]. Rop occurred commonly among infants with a birth weight of 1,501-2,000 g. The risk factors were gestational age at birth septicemia and perinatal asphyxia
