Does asthma or treatment with theophylline limit childrens academic performance?
GROUND: Asthma is a major cause of morbidity in childhood, restricting activity and causing absences from school. Theophylline, although effective in managing chronic asthma, has been reported to cause deficits in cognitive functioning and school performance. We therefore examined the effect of asthma and its treatment on academic achievement in a large, representative population of school-age children; matched sibling controls were used for comparison. METHODS: We identified 255 consecutive children with asthma (mean age, 12.0 years) who had taken nationally standardized scholastic achievement tests administered routinely by the schools.
