Review Meta Analysis
Vitamin D with asthma and COPD: not a false hope? A systematic review and meta-analysis.
Vitamin D deficiency and insufficiency are increasingly being recognized in the general population over the last few decades. However, a number of other disorders have now been linked to vitamin D deficiency and insufficiency, including asthma and COPD. The aim of this study was to evaluate the evidence on the effect of vitamin D on asthma and COPD. ⋯ Vitamin D deficiency was associated with a significant decrease in lung function in asthmatic children. Vitamin D deficiency was highly prevalent in asthma patients, and vitamin D status was associated with lung function. COPD cannot be considered as completely free of vitamin D deficiency.
