Aim: To examine whether caloric intake during the first week of age influences the risk of Bronchopulmonary Dysplasia (BPD) in extremely preterm infants.
Methods: In this retrospective cohort study, all infants born with gestational age < 29 weeks over 30 months period were eligible for the study. Infants with major congenital anomalies and those who died before 36 weeks postmenstrual age were excluded. We compared the nutritional characteristics between infants who developed BPD and those without BPD.
Results: Of the 262 eligible infants, 233 were included for the study. A total of 125 infants developed BPD. Infants with BPD had similar fluid intake in the first week of life to other infants with no BPD. After adjusting for gestational age, severity of illness and PDA, BPD was associated a trend towards reduced cumulative protein intake in the first week of life (OR=0.91 95% CI: 0.81-1.01). Increase time to reach full feed is associated with increased risk of BPD (OR=1.03; 95%CI: 1.00 - 1.06).
Conclusions: In preterm infants born at less than 29 weeks, provision of adequate calorie intake particularly protein in the first week of life may associate with decreased risk of BPD.
