Perinatal Factors in Newborn Are Insidious Risk Factors for Childhood Autism Spectrum Disorders: A Population-based Study.

A Taiwan team tracked every child born in one year. They later checked who got an autism diagnosis.

They looked at four newborn problems: jaundice, low blood sugar, slow growth in the womb, and unusual face or head shape.

The study used health records, so families did not need to fill out forms.

All four problems raised the odds of later autism. Slow growth and head-shape issues carried the biggest jump.

The group was large, so the link looks real for Taiwan babies.

Robinson et al. (2011) pooled 13 studies and saw the same jaundice signal. The Taiwan data fit right inside that older meta-analysis.

Mamidala et al. (2013) in India also found jaundice and birth stress linked to autism. Two continents, same story.

Chien et al. (2019) went one step further. They showed that kids with autism plus these birth issues had worse stereotypy and social scores. Risk factor papers now connect to day-to-day symptom strength.

When you review a child’s history, note jaundice, low sugar, slow growth, or craniofacial differences. Flag these kids for extra developmental checks. Early watch means earlier teaching and better outcomes.
