NIDCD Outcomes Research in Children with Hearing Loss December 12 and 13, 2006 Bethesda, Maryland
  • Exam measures for children, ages 6 to 19 years:
    • "...estimates of 43,000 and 33,000 with profound bilateral HL."
    • "...the estimates are 30,000 and 16,000 with severe HL (better ear)."
    • "...the estimates are 136,000 and 96,000 with moderate HL (better ear)."
    • "...the estimate is 791,000 with mild HL (better ear)."
    • "Except for children with profound bilateral hearing loss, the total estimate in 2005 is likely 903,000 to 957,000 children with mild, moderate, or severe HL (better ear), ages 6 to 19 years."
    • "The prevalence of “unilateral” mild, moderate, or severe HL in worse ear and normal hearing in better ear was 4.9% and 5.7% in NHANES II and NHANES III, respectively, which corresponded to 2.6 and 2.8 million children. Adjusting for the 2005 population increase, the estimates are 2.8 and 3.0 million with mild, moderate, or severe unilateral HL (worse ear)."
  • Exam measures for children, ages 0 to 5 years:
    • "In 2005, 25 million U.S. children were 0 to 5 years of age. Since nationally representative hearing examination data are lacking for children in this age range, incidence statistics3 derived from States with newborn hearing screening programs are used as a surrogate."
    • "The following illustrates the calculation: given an incidence rate in 2004 for newborn HL of 1.11 per 1,000 live births, then 0.00111 X 3.95 million U.S. births = 4,385. After multiplying by 6 years (i.e., ages 0 to 5 years), the estimate is 26,310 children with HL since birth."
    • "After adjusting for other known etiologies (CMV, meningitis, injuries, etc.) of acquired early childhood HL, the overall estimate is at least 30,000 children with HL (primarily moderate, severe, or profound HL) below 6 years of age."
