The relationship between the occurrence of otitis media with effusion during the first 3 years of life and subsequent verbal and academic performance was examined in 61 socioeconomically disadvantaged children who attended a research day-care program. Study children were participants in a longitudinal study of child development in which the number of episodes of otitis media and duration of each otitis episode were reported prospectively from infancy. The incidence of otitis media was highest during the first 2 years of life. Bilateral otitis media accounted for 66% of the days with otitis media with effusion. Standardized tests of intelligence and academic performance were administered to the children when they were 3 1/2 to 6 years of age. No evidence of associations between measures of early childhood otitis media experience and these measures of verbal or academic functioning was found in this study population.
