A large new study out of Israel and published in Allergy has found that vitamin D deficiency significantly increases the risk of adult asthma exacerbations and morbidity, but does not influence risk of physician-diagnosed asthma.
While asthma is a lifelong chronic condition, much of the focus on this condition is during childhood where the majority of diagnoses occur. Often overlooked is the similar prevalence rates in adults. A 2012 survey revealed that the prevalence of asthma in children was 9.3% compared to 8.0% in adults.
Adults with asthma experience unique complications related to their age of diagnosis, such as an increased number of sick days taken because of asthma-associated symptoms.
