In 2003, five million school-aged children and youth nationwide were reported to have asthma, and 3.1 million had experienced an asthma episode or attack within the previous year. Asthma is one of the leading causes of school absenteeism, which can negatively affect students’ academic performance. In the Albuquerque/Bernalillo County area of New Mexico, an estimated 10,000 school-aged children have asthma.
