Preschool wheezing and prognosis at 10

Area of Science:

• Pediatric Respiratory Health
• Epidemiology
• Childhood Asthma

Background:

• Wheezing is a common symptom in early childhood.
• Predicting the persistence of childhood wheezing is crucial for effective management.
• Longitudinal data are needed to understand wheezing trajectories.

Purpose of the Study:

• To investigate the long-term prognosis of childhood wheezing.
• To identify factors associated with persistent wheezing at age 10.
• To compare outcomes for children with and without an asthma diagnosis.

Main Methods:

• Utilized data from the Child Health and Education Study, a national cohort.
• Collected information at birth, 5, and 10 years of age.
• Compared wheezing history before age 5 with wheezing status at age 10 in 11,465 children.

Main Results:

• 80% of children with wheezing attacks before age 5 were wheeze-free at age 10.
• The frequency of wheezing attacks before age 5 correlated with persistent wheezing at age 10.
• Children diagnosed with asthma at age 5 were significantly more likely to wheeze at age 10.

Conclusions:

• Childhood wheezing often resolves by age 10, particularly with infrequent episodes.
• An asthma diagnosis by age 5 is a strong predictor of persistent wheezing.
• Further follow-up is required to determine long-term relapse rates after remission.
