<jats:p> Asthma is the most common chronic pediatric medical condition in the United States and accounts for significant morbidity, particularly among minority and disadvantaged populations. Hypovitaminosis D is also highly prevalent throughout the developed world, and many of the risk factors for hypovitaminosis D and asthma are the same. Several recent observational studies have documented a correlation between asthma severity and vitamin D levels; however, there is no strong evidence for causality yet. Until trials of vitamin D supplementation among children with asthma are performed, the role of low levels of vitamin D in causing asthma morbidity will remain unclear. </jats:p>
