Early Otitis Media may adversely impact auditory and language development in children, finds study

Otitis media is a common disorder of early childhood suspected of hindering auditory and language development, but evidence regarding these effects has been contradictory. To examine potential sources of these contradictory past results and explore in more detail the effects of early otitis media on auditory and language development, three specific hypotheses were tested: (1) Variability in children’s general attention could influence results, especially for measures of auditory functioning, leading to spurious findings of group differences; (2) Different language skills may be differentially affected, evoking different effects across studies depending on skills assessed; and (3) Different mechanisms might account for the effects of otitis media on acquisition of different language skills, a finding that would affect treatment choices. Children 5–10 years old participated: 49 with and 68 without significant histories of otitis media. The auditory function examined was temporal modulation detection, using games designed to maintain children’s attention; two additional measures assessed that attention. Measures of lexical knowledge and phonological sensitivity served as the language measures.Results: Sustained attention was demonstrated equally across groups of children with and without histories of otitis media. Children with histories of otitis media performed more poorly than peers without those histories on the auditory measure and on both sets of language measures, but effects were stronger for phonological sensitivity than lexical knowledge. Deficits in temporal modulation detection accounted for variability in phonological sensitivity, but not in lexical knowledge. When experimental factors are tightly controlled, evidence emerges showing effects of otitis media early in life on both auditory and language development. Mechanism of effects on language acquisition appear to involve both delayed auditory development and diminished access to the ambient language.
