Identification of early risk factors for language impairment.
The current study is a population-based investigation of birth risk factors for school-identified specific language impairment (SLI). The sample consisted of 244,619 students (5,862 SLI) born in Florida between 1989 and 1990 who were in the Florida public school system at ages 6-7. Epidemiological measures of effect were used to investigate both individual- and population-level risk for SLI. Very low birth weight (VLBW), low 5-min Apgar score, late or no prenatal care, high birth order, and low maternal education were associated with highest individual-level risk. Low maternal education and having an unmarried mother was associated with the highest population-level risk. The results not only suggest who needs to be screened for a future developmental disability, but identify a group of children who are at-risk for an SLI placement in school. Early intervention services for these children may be the most effective approach to reducing the incidence of school-identified SLI.
