Early allergy sensitization and respiratory infections in young children may have lasting impacts on lung health, according to a recent study. The research reveals that for children sensitized to allergens, more months with respiratory infections correlate with poorer lung function as adults.This finding suggests a crucial link between early childhood illnesses and long-term respiratory health, highlighting the importance of monitoring and prevention strategies for children with allergy sensitization. Understanding this connection is vital for improving adult lung function. The study examined children with a family history of allergic disease, tracking respiratory health and allergy sensitization to determine future lung function.

Early Allergy Sensitization and infections Linked to Adult Lung Function
Updated june 09, 2025
Children who develop sensitivity to common allergens early in life may experience lasting effects on their lung health, according to a new study. The research suggests that early respiratory tract infections, when combined with allergy sensitization,can negatively impact lung function into adulthood.
The australian study, led by Shyamali C. Dharmage of The University of melbourne, tracked 620 infants born between 1990 and 1994. The children, 51.1% of whom were boys,all had a family history of allergic disease. Parents reported on their children’s respiratory health until age 2, and the children underwent skin prick testing to determine allergy sensitization. Lung function was then assessed at ages 18 and 25 using spirometry.
the findings, published in Pediatric Allergy and Immunology, revealed a meaningful link between early respiratory infections and later lung function.Among children with allergen sensitization, each additional month of respiratory tract infection in the first two years of life was associated with decreased lung function at age 25. Specifically, researchers observed a decrease in the forced expiratory volume in one second (FEV1).
Interestingly,the opposite effect was observed in children without sensitization. For them,each additional month of respiratory illness was associated with an increase in lung function.
“Even in the absence of reported chronic respiratory symptoms, close monitoring and prevention of recurrent respiratory infections in children with sensitization may help minimize disease progression and functional impairment, and thereby enable attainment of optimal adult lung function,” the authors wrote.
What’s next
The study authors recommend close monitoring and prevention of recurrent respiratory infections in sensitized children to promote optimal adult lung function. Further research could explore interventions to mitigate the negative impact of early infections on lung development in at-risk children.
