Identification of early risk factors for language impairment.

McIntyre et al. (2002) looked at birth records and later school records. They wanted to know which babies end up with language problems.

They checked things like birth weight, Apgar scores, and mom’s education. The study covered many kids across the United States.

Very low birth weight, low Apgar scores, and late prenatal care raised risk. So did high birth order and low maternal education.

Low maternal education and unmarried status hit the whole population hardest. These two flags matter most when you plan screenings.

Stewart et al. (2018) extends these birth flags into school. They show many 7- and 11-year-olds with poor vocabulary still slip past teachers. Birth risk lists are only step one; you still need school-wide language checks.

Fahmie et al. (2013) used the same big-cohort style but tracked intellectual disability instead of language. Again, mom’s education stayed predictive after removing genetic cases. The pattern repeats across diagnoses.

DeRoma et al. (2004) found nearly identical red flags in Pakistan: maternal illiteracy and small head size. Risk factors look similar around the world.

You can spot likely language trouble before kindergarten. Flag every child born very small, with low Apgar, or whose mother left school early. Add them to your early-language screening list. Do not wait for teacher concern; Stewart et al. (2018) prove many will be missed.
