Association between preeclampsia and autism spectrum disorder: a population-based study / Gillian M. MAHER in Journal of Child Psychology and Psychiatry, 61-2 (February 2020)
[article]
Titre : Association between preeclampsia and autism spectrum disorder: a population-based study Type de document : Texte imprimé et/ou numérique Auteurs : Gillian M. MAHER, Auteur ; Gerard W. O'KEEFFE, Auteur ; Christina DALMAN, Auteur ; Patricia M. KEARNEY, Auteur ; Fergus P. MCCARTHY, Auteur ; Louise C. KENNY, Auteur ; Ali S. KHASHAN, Auteur Article en page(s) : p.131-139 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder epidemiology preeclampsia Index. décimale : PER Périodiques Résumé : BACKGROUND: The environmental contribution of autism spectrum disorder (ASD) is approximately 17%-50%, highlighting the importance of investigating factors potentially contributing to the likelihood of its development, and of gaining a greater understanding of the pathogenesis surrounding ASD. The objective of this study was to examine the association between preeclampsia and ASD using a population-based cohort study. METHODS: All singleton live births in Sweden from 1982 to 2010 were included, using data from Swedish National Registers. Exposures of interest included: (a) preeclampsia (classified according to ICD-8, ICD-9 and ICD-10) and (b) preeclampsia and small for gestational age (SGA) combined, used as a proxy for preeclampsia with placental dysfunction. ASD status was based on ICD-9 and ICD-10. The cohort consisted of 2,842,230 children, with 54,071 cases of ASD. Follow-up began from the child's first birthday, and data were censored at first diagnosis of ASD, death, migration or end of study period (31st December 2016). We conducted multivariate Cox proportional hazards regression analysis, adjusting for several perinatal and sociodemographic factors, selected a priori. We further controlled for shared genetic and familial confounding using sibling-matched analysis. RESULTS: In the adjusted Cox proportional hazards regression analysis, preeclampsia was associated with a 25% increase in the likelihood of ASD (Hazard Ratio (HR): 1.25, 95% CI:1.19, 1.30) compared with those unexposed to preeclampsia, while in the sibling-matched analysis the HR was 1.17 (95% CI: 1.06, 1.28). The HR for preeclampsia and SGA combined was 1.66 (95% CI: 1.49, 1.85) in the adjusted Cox model and 1.95 (95% CI: 1.53, 2.48) in the sibling-matched analysis. CONCLUSIONS: Exposure to preeclampsia or preeclampsia/SGA (i.e. SGA baby exposed to preeclampsia) was associated with ASD. The stronger association with preeclampsia/SGA than preeclampsia alone suggests that placental pathology may be a mechanism for the increased likelihood of ASD.
