Impact of Vitamin D Supplementation on Recurrent Respiratory Infections in Paediatric Primary Care.
Summary
Up to date, some clinical trial have evaluated the efficacy and safety of Vitamin D supplementation in children with RRI, with no conclusive information. Therefore, the investigators designed a prospective, single-blind, clinical trial to evaluate whether oral supplementation with vitamin D from October to April reduces the global health burden of recurrent respiratory tract infections in a primary care setting. The primary outcome was evaluated if Vitamin D supplementation during autumn and winter can reduce the number of respiratory tract infections in children diagnosed with recurrent respiratory tract infections the seasons before. Secondary objectives was the assessment of Vitamin D supplementation benefits on global socioeconomic burden of recurrent respiratory tract infections in a primary care setting, according to number of visits to the primary care paediatrician and use of antibiotics due to respiratory tract infections.
