Approximately 120,000 Arizona children have asthma. Asthma attacks lead to 3,000 hospitalizations each year costing Arizonans approximately $24 million in direct medical costs. To address this public health issue, the Mel and Enid Zuckerman College of Public Health at the University of Arizona has partnered with the American Lung Association in Arizona and the Tucson Unified School District to implement a school-based asthma program in selected elementary schools.
