    Background: Evidence about the effect of intrauterine exposure to pre-eclampsia on offspring autism-spectrum disorder (ASD) is not well established. Aims To examine the association between pre-eclampsia and ASD. Method: PubMed, Embase and PsycINFO databases were searched. Pooled relative risks (RR) with 95% confidence intervals were calculated. Subgroup and sensitivity analyses were performed. Heterogeneity was assessed using Cochran's Q- and the I 2-test. The presence of publication bias was evaluated by Egger's test and visual inspection of the symmetry in funnel plots. Results: Ten studies meet the inclusion criteria. The risk of ASD was 32% higher in offspring who had intrauterine exposure to pre-eclampsia compared with those not exposed (RR = 1.32, 95% CI 1.20-1.45). Sensitivity analysis revealed consistent pooled estimates ranging from RR = 1.30 (95% CI 1.17-1.44) to RR = 1.37 (95% CI 1.26-1.48). We found no significant heterogeneity and evidence of publication bias. Conclusion: Pre-eclampsia increased the risk of ASD in offspring. The finding suggests a need for early screening for ASD in offspring of women with pre-eclampsia. Declaration of interest None.
