Insights
Bronchopulmonary dysplasia (BPD) in preterm infants is linked to a higher risk of developmental delays. This study confirms the persistent association between BPD and neurodevelopmental outcomes in premature children.
Area of Science:
- Neonatal Medicine
- Pediatric Neurology
- Developmental Pediatrics
Background:
- Bronchopulmonary dysplasia (BPD) management and pathophysiology are evolving.
- The neurodevelopmental consequences of BPD require ongoing investigation.
Discussion:
- This study re-evaluates the association between BPD and developmental delay in a contemporary cohort.
- Understanding persistent risks is crucial for early intervention strategies.
Key Insights:
- Bronchopulmonary dysplasia (BPD) significantly increases the risk of developmental delay in preterm children.
- The association was confirmed using the Age & Stages Questionnaires (ASQ) at 24 months corrected age.
- An odds ratio of 1.52 (95% CI 1.11-2.08) highlights the strength of this association.
Outlook:
- Further research should explore specific interventions to mitigate neurodevelopmental risks in infants with BPD.
- Longitudinal studies are needed to track the long-term developmental trajectories of children with BPD.
Background:
Overall and respiratory management of preterm children are constantly evolving, which might have changed both the pathophysiology and neurodevelopmental consequences of bronchopulmonary dysplasia (BPD).
Objectives:
The objective of this study is to determine whether the previously shown association between BPD and risk of developmental delay persists.
Methods:
The study population was children born before 32 weeks' gestation from the French prospective cohort EPIPAGE-2. The exposure was BPD assessed at 36 weeks' postmenstrual age. The main outcome was risk of developmental delay defined by an Age & Stages Questionnaires (ASQ) score below threshold at 24 months' corrected age.
Results:
The analyzed population included 2,706 children. Among those with available ASQ score, 196/1,587 had BPD and 671/1,587 had an ASQ score below threshold. BPD was associated with an ASQ score below threshold (odds ratio 1.52, 95% confidence interval 1.11-2.08; p = 0.008).
Conclusions:
BPD was strongly associated with risk of developmental delay.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
