Asthma-like symptoms in young children are common, and this study investigated the risk factors and their age-related impact on the symptom burden. The results showed that male sex, maternal asthma, low birth weight, maternal antibiotic use, high asthma exacerbation polygenic risk score, and high airway immune score were associated with a higher number of episodes. The impact of certain risk factors increased with age, while others remained stable.
BACKGROUND: Episodes of asthma-like symptoms in young children are common, but little is known about risk factors and their patterns for the daily symptom burden.OBJECTIVE: We investigated a variety of possible risk factors and their age-related impact on the number of asthma-like ep-isodes during age 0 to 3 years.METHODS: The study population included 700 children from the Copenhagen Prospective Studies on Asthma in Childhood2010 mother-child cohort followed prospectively from birth. Asthma-like symptoms were recorded until age 3 by daily diaries. Risk factors were analyzed by quasi-Poisson regressions, and interaction with age was explored.RESULTS: Diary data were available in 662 children. Male sex, maternal asthma, low birth weight, maternal antibiotic use, high asthma exacerbation polygenic risk score, and high airway immune score were associated with a higher number of episodes in a multivariable analysis. Maternal asthma, preterm birth, caesarean section, and low birth weight showed an increasing impact with age, whereas sibling(s) at birth showed a decreased association with age. The remaining risk factors had a stable pattern during age 0 to 3 years. For every additional clinical risk factor (male sex, low birth weight, and maternal asthma) a child had, we found 34% more episodes (incidence rate ratio: 1.34, 95% confidence interval: 1.21-1.48; P < .001).CONCLUSION: Using unique day-to-day diary recordings, we identified risk factors for the burden of asthma-like symptoms in the first 3 years of life and described their unique age-related patterns. This provides novel insight into the origin of asthma -like symptoms in early childhood that potentially pave a path for personalized prognostics and treatment.& COPY; 2023 American Academy of Allergy, Asthma & Immunology (J Allergy Clin Immunol Pract 2023;11:1773-84)
