Abstract

Schizophrenia and autism spectrum disorder (ASD) are significant public health problems. Scientists have recently explored the association between schizophrenia and ASD, but the findings are inconsistent. Thus, we conducted a systematic review and meta-analysis of epidemiological studies to examine the association between schizophrenia and ASD. PubMed, Embase, and the Cochrane Library were used for literature searches to identify eligible studies published in English before October 2, 2017. Relevant studies estimating the association between schizophrenia and ASD were included. The meta-analysis of the prevalence of schizophrenia in individuals with ASD encompassed 1,950,113 participants and 14,945 individuals with ASD. A random-effects model was chosen to synthesize the effect sizes of individual studies. The prevalence of schizophrenia was significantly higher in individuals with ASD than in controls (odds ratio = 3.55, 95% confidence interval: 2.08-6.05, P < .001). Both sensitivity analysis and publication bias testing revealed that the findings were robust. The systematic review of the prevalence of ASD in individuals with schizophrenia encompassed 930 participants. The prevalence of ASD in individuals with schizophrenia ranged from 3.4 to 52%. The systematic review and meta-analysis showed a significant association between schizophrenia and ASD.

LAY SUMMARY: This systematic review and meta-analysis explored the association between schizophrenia and ASD. We found that the prevalence of schizophrenia was significantly higher in individuals with ASD than in controls and the prevalence of ASD in individuals with schizophrenia ranged from 3.4 to 52%. A comprehensive estimation of schizophrenia and ASD has important implications for the diagnosis, treatment, prognosis, and development of a fundamental understanding of these disorders.
