Conclusions:
This case control study involving 143 children between 2 and 6 y with autism as per CARS criteria and a control group of 200 normal children has shown that upper and upper middle socioeconomic status and (ii) male gender are significant risk factors for autism, whereas place of residence, rule is a protective factor.
