Early childhood bronchiolitis increases asthma risk in adulthood

People who have had bronchiolitis in early childhood have an increased risk of asthma at the age of 28-31 and a weaker health-related quality of life than their peers. In lung function tests, they also demonstrate changes indicative of irreversible airway obstruction, according to a new study. Bronchiolitis and pneumonia are common lower respiratory tract infections in early childhood. During their first year, around 30 per cent of children have bronchiolitis, leading to hospitalization in 1 to 3 per cent.
