Brief report: incidence of and risk factors for autistic disorder in neonatal intensive care unit survivors.

Doctors tracked 5 271 babies who had stayed in a neonatal intensive care unit. They counted how many later received an autism diagnosis. They also looked for birth events that might raise the risk.

Thirty-four of every 10 000 NICU graduates developed autism. That rate is about double the usual count in Japan at the time. Babies who had inhaled their first stool during labor showed the clearest added risk.

Gillberg et al. (1983) first showed that autistic children have more pre-birth and birth problems. Jolliffe et al. (1999) now says the same pattern shows up inside a NICU sample.

Cryan et al. (1996) and Dall et al. (1997) did not find extra birth trouble between autistic kids and matched controls or siblings. The gap is simple: those studies looked at typical births, while NICU babies already carry higher medical load.

Lee et al. (2022) used a whole-country database and still found neonatal jaundice, low sugar, growth delay and face-shape anomalies raising autism odds. Their larger numbers firm up the 1999 signal.

If you serve toddlers who left the NICU, flag any history of meconium aspiration. Add extra developmental screens at 12, 18 and 24 months. Early signs can be subtle, but catching them fast gets intervention rolling sooner.
