Abstract
- PURPOSE
Wheezing following viral lower respiratory tract infections (LRTIs) in children <2 years of age is an important risk factor for the development of asthma later in life; however, not all children with viral LRTIs develop wheezing. This study investigated risk factors for the development of wheezing during viral LRTIs requiring hospitalization.
METHODS
The study included 142 children <2 years of age hospitalized for LRTIs with at least one virus identified as the cause and classified them into children diagnosed with LRTIs with wheezing (n=70) and those diagnosed with LRTIs without wheezing (n=72).
RESULTS
There were no significant differences in the viruses detected between the two groups. Multivariate logistic regression analysis showed that, after adjusting for potentially confounding variables including sex and age, the development of wheezing was strongly associated with parental history of allergic diseases (adjusted odds ratio [aOR], 20.19; 95% confidence interval [CI], 3.22-126.48), past history of allergic diseases (aOR, 13.95; 95% CI, 1.34-145.06), past history of hospitalization for respiratory illnesses (aOR, 21.36; 95% CI, 3.77-120.88), exposure to secondhand smoke at home (aOR, 14.45; 95% CI, 4.74-44.07), and total eosinophil count (aOR, 1.01; 95% CI, 1.01-1.02).
CONCLUSION
Past and parental history of allergic diseases, past history of hospitalization for respiratory illnesses, exposure to secondhand smoke at home, and total eosinophil count were closely associated with the development of wheezing in children <2 years of age who required hospitalization for viral LRTIs. Clinicians should take these factors into consideration when treating, counseling, and monitoring young children admitted for viral LRTIs.
