  4. Early Childhood Longitudinal Study • Multi-dimensional study focusing on the early home and educational experiences of children through first 6 years of life • Birth cohort (ECLS-B), 2001 • Nationally representative sample

  5. ECLS Conceptual Model

  6. Study Design of ECLS-B • N=10,688 • Oversamples • Minorities • Very low birth weight (<1500 g) • Moderately low birth weight (1500 - 2499 g) • Twins • Household surveys conducted by trained personnel at 9 months • Bayley exams (modified for ECLS-B) conducted at 9 months and 2 years

  7. Early Childhood Longitudinal Study For more information visit: http://nces.ed.gov/ecls/index.asp

  8. EHDI Annual data collection State-level outcome data Hearing screening Hearing loss Dx Enrollment in intervention program Global screening rate ≈65% before discharge ECLS-B One year (2001) births only Person-level outcome data Hearing screening Hearing loss Dx Receiving hearing services Global screening rate ≈70% before discharge 78% by 9 months EHDI vs. ECLS-B, 2001

  21. Infants Receiving Hearing Services at 9 Months(n=105) ―Univariate Associations

  22. Infants Receiving Hearing Services at 9 Months (n=105) Source: 9-month parent CAPI instrument and parent questionnaire

  23. Summary of Findings • Lower screening rate for Hispanic/Latino infants • Lower mother’s education associated with lower screening rate • Infants with low birth weight and associated conditions have a higher rate of screening • Infants receiving hearing services at 9 months also receive many additional services

  24. Prospectus • EHDI • Annual data collection allows trend analysis to document increase in newborn hearing screening • Anticipate more extensive data will come in future years • ECLS-B • Longitudinal study allows tracking of children with hearing problems (9 months of age – this study) • Future data will be collected for children when 2, 4, 5 (kindergarten), and 6 (first grade) years old
