Tóm tắt

 The association between early childhood serum 25-hydroxyvitamin D (25(OH)D) and eosinophilic asthma remains unclear. We investigated this association using multicentre prospective data from 584 children with a history of bronchiolitis requiring hospitalisation (high-risk population). Low serum 25(OH)D levels (<
 20 ng/mL) were associated with increased odds of developing eosinophilic asthma (adjusted OR 2.33
  95% CI 1.23, 4.40
  p=0.01) as compared with children with serum 25(OH)D of 20-39.9 ng/mL. Our data facilitate further investigation into the potential role of early-life vitamin D supplementation among children with a history of severe bronchiolitis and eosinophilia for preventing childhood asthma.
