Short answer · Medically reviewed summary · Last updated: 2023-07-13
Bronchopulmonary Dysplasia (BPD) is a chronic lung disease that primarily affects premature infants who have received mechanical ventilation or oxygen therapy for respiratory distress syndrome. It is characterized by abnormal development of lung tissue and inflammation, leading to respiratory symptoms and long-term complications. The prevalence of BPD varies depending on several factors, including gestational age, birth weight, and the level of neonatal care provided.
What is the prevalence of Bronchopulmonary Dysplasia (BPD)?
Prevalence of Bronchopulmonary Dysplasia (BPD): how many people are affected worldwide, differences by sex and region, with sources.
Bronchopulmonary Dysplasia (BPD) is a chronic lung disease that primarily affects premature infants who have received mechanical ventilation or oxygen therapy for respiratory distress syndrome. It is characterized by abnormal development of lung tissue and inflammation, leading to respiratory symptoms and long-term complications.
The prevalence of BPD varies depending on several factors, including gestational age, birth weight, and the level of neonatal care provided. On average, BPD affects approximately 10-15% of premature infants born in developed countries.
Infants born extremely prematurely, before 28 weeks of gestation, have a higher risk of developing BPD, with prevalence rates ranging from 40-60%. In contrast, infants born closer to full term, between 32-36 weeks of gestation, have a lower risk, with prevalence rates around 5-10%.
It is important to note that advancements in neonatal care have led to improved survival rates for extremely premature infants, but this has also contributed to an increased incidence of BPD. The long-term consequences of BPD can include respiratory difficulties, impaired lung function, and potential developmental delays.
