Summary

Asthma and chronic obstructive pulmonary disease (COPD) are diseases that affect a person's ability to breathe normally. People who do not receive enough vitamin D may have a higher risk of developing asthma or COPD. This study will examine previously collected blood samples of participants in three studies to determine whether people with low vitamin D levels have an increased risk of severe asthma or COPD.
