4. Pregnancy/Birth Complications
Babies born before 26 weeks of gestation may be at greater risk of developing autism, and the disorder is more likely to occur in babies with low birth weights. Autism is also more prevalent in multiple-birth babies, such as twins and triplets.4‘What Causes Autism?’ Autism Speaks, www.autismspeaks.org/what-causes-autism.
A mother who experiences bleeding, preeclampsia, gestational diabetes or hypertension during her pregnancy is more likely to give birth to a child with autism. A child whose mother previously experienced a miscarriage has an increased chance of developing autism.7Gardener, Hannah, et al. ‘Prenatal Risk Factors for Autism: Comprehensive Meta-Analysis.’ The British Journal of Psychiatry : the Journal of Mental Science, U.S. National Library of Medicine, July 2009, www.ncbi.nlm.nih.gov/pmc/articles/PMC3712619/.
