The meta-analysis of case–control and cohort studies was conducted to obtain the association between breech presentation and the risk of autism spectrum disorder (ASD) among children. The search for relevant studies in major electronic databases was performed including; Web of Science, PubMed and Scopus up to May 2018. The odds ratio (ORs) with 95% confidence intervals (CI) was extracted from eligible studies. The pooled estimate of OR was not indicated a significant association between breech presentation and risk of ASD among children (OR = 1.15, 95% CI = 0.93–1.37), but this association was significant in the unadjusted analysis (OR = 1.32, 95% CI = 1.05–1.58). Our findings were not showed that breech presentation is associated with increased risk of ASD among children.
