Study: Autism Risk Factors Elusive

Research has hinted that various factors around the time of birth may raise a child's risk of autism later in life, but there is still too little evidence to point to specific culprits, a U.S. study said.
Experts have long believed that genes play a key role in autism risk, but a U.S. study released last week found that genes appeared to explain a much smaller portion of the risk than previously suggested.
The latest study, a review published in Pediatrics of 40 previous studies, found that factors including low birth weight, fetal distress during labor and signs of "poor condition" in the newborn, such as problems with breathing or heart rate, have been linked to the risk of autism.
