Relationship between bronchopulmonary dysplasia, long-term lung function, and vitamin D level at birth in preterm infants

The level of serum 25-(OH)D in preterm infants at birth is closely related to the occurrence of BPD and long-term lung function damage, and is affected by multiple high-risk factors. This study provides a theoretical basis for the individualized treatment of preterm infants and the early prevention of BPD.
