Long-term outcome of early childhood hearing impairments in northern Finland

Early childhood hearing impairment (HI) may have a marked negative effect on educational outcome and employment status in adulthood. The late outcome of 51 Finnish mildly to profoundly HId children born in the period 1965-1979 was studied using a questionnaire posted to the subjects. Subjects included in the study had an early childhood sensorineural, non-syndromal hearing impairment with no known associated handicaps. The response rate to the inquiry was as high as 88% (45/51). The subjects had qualified educationally at a somewhat lower level than their age peers according to nationwide statistics; 48% of the respondents belonging to the labour force were currently unemployed (versus 15% of all the 25-to 29-year-olds in Finland in 1997), but their employment status was not associated with the HI grade. In particular, the severely and profoundly HId often had needed special support from the employment authorities to find work.
