Growth and nutrition in children with established bronchopulmonary dysplasia: A review of the literature

Background Bronchopulmonary dysplasia (BPD) remains the most common late morbidity of preterm birth. Clinical care and research have largely focused on the pathogenesis and prevention of BPD. Preterm infants who develop BPD have significant medical needs that persist throughout their hospital course and continue after discharge, including those associated with growth and nutrition. The objective of this study was to review the available literature on nutrition and growth in infants with established BPD and to identify the knowledge and research gaps to provide direction for future studies. Methods We conducted a literature search in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using Ovid MEDLINE, CINAHL, and Embase. Titles, abstracts, and full texts were independently reviewed by the authors and selected based on predetermined inclusion/exclusion criteria. Results were summarized qualitatively. Results Excluding duplicates, 2315 articles were identified. Thirty articles were selected for inclusion. We identified the following key components of nutrition support and clinical care: energy expenditure, growth, and metabolism; body composition; enteral nutrition; supplements; parenteral nutrition; and respiratory outcomes. Conclusions Despite a large body of literature describing the role of growth and nutrition in the prevention of BPD, research is lacking with respect to interventions and management in the population with established BPD. Thus, organized approaches for clinical interventions and trials with respect to growth and nutrition in infants and young children with established BPD are needed. These studies should include multiple centers because of the small numbers of patients with BPD at each site.
