The researchers enrolled 86 children in the study, including 36 children with STRA, 26 with moderate asthma and 24 non-asthmatic controls, and measured the relationships between vitamin D levels and lung function, medication usage and symptom exacerbations.
The researchers also examined tissue samples from the airways of the STRA group to evaluate structural changes in the airway's smooth muscle.
At the conclusion of the study the researchers found children with STRA had significantly lower levels of vitamin D, as well as greater numbers of exacerbations, increased use of asthma medications and poorer lung function compared to children with moderate asthma and non-asthmatic children.
The STRA effort aims to use Alabama's resources to increase technological innovation in Alabama in order to remain competitive with other states and regions and to advance the number of science and technology positions available within the state.
The STRA effort is not just an advancement for the I.
Governor Bob Riley has been a strong supporter of STRA and acknowledges its importance to future economic development and growth in Alabama.
