| Outline of Final Research Achievements |
Objective: We aimed to clarify whether low-dose, short-term vitamin D supplementation, in addition to standard treatments, improves control of childhood asthma. Methods: We conducted a randomized, double-blind, placebo-controlled trial comparing vitamin D3 supplements (800 IU/day) with placebo for 2 months in schoolchildren with asthma. The primary outcome was changes of asthma control levels defined by the Global Initiative for Asthma (GINA) at 2 months and 6 months. Results: Japanese schoolchildren with asthma (n=89) were randomly assigned to receive vitamin D (n=54) or placebo (n=35). At 2 months, GINA were significantly more improved in the vitamin D group compared with the placebo group (P=0.015). Conclusion: Low-dose, short-term vitamin D supplementation in addition to standard treatment may improve levels of asthma control in schoolchildren.
