  1. Prevalence and characteristics of children with serious hearing impairment in Metropolitan Atlanta, 1991-1993.

    Article - En anglais


    There is a paucity of data describing the epidemiology of serious hearing impairment among children in the United States.

    This report provides information on the prevalence of serious hearing impairment among children born in the 1980s and living in the metropolitan Atlanta area in 1991-1993 and on the characteristics of children with serious hearing impairment.


    Data for this report are drawn from the Metropolitan Atlanta Developmental Disabilities Surveillance Program, an ongoing, active case-ascertainment system for mental retardation, cerebral palsy, hearing impairment, and vision impairment among children 3 to 10 years of age.

    Hearing impairment was defined as a bilateral, pure-tone hearing loss at frequencies of 500,1000, and 2000 Hz averaging 40 decibels or more, unaided, in the better ear.

    Both severity and type of hearing loss were examined.

    Cross-sectional as well as birth cohort prevalence rates of serious hearing impairment were computed by sex and by race.

    The presence of mental retardation, cerebral palsy, vision impairment, or a seizure disorder was also assessed.

    An attempt was made to determine the probable etiology of a subset of the cases.


    The average, annual prevalence rate for moderate to profound hearing loss was 1.1 per 1000.

    The prevalence rate increased steadily with age.

    Ninety percent of all cases for which the type of loss was recorded were sensorineural.

    The highest rate was seen among black male children (1. (...)
