Maternal migration and autism risk: Systematic analysis

Crafa, Daina, Warfa, Nasir·2015·International Review of Psychiatry

Abstract

Autism (AUT) is one of the most prevalent developmental disorders emerging during childhood, and can be amongst the most incapacitating mental disorders. Some individuals with AUT require a lifetime of supervised care. Autism Speaks reported estimated costs for 2012 at £34 billion in the UK; and $3.2 million-$126 billion in the US, Australia and Canada. Ethnicity and migration experiences appear to increase risks of AUT and relate to underlying biological risk factors. Sociobiological stress factors can affect the uterine environment, or relate to stress-induced epigenetic changes during pregnancy and delivery. Epigenetic risk factors associated with AUT also include poor pregnancy conditions, low birth weight, and congenital malformation. Recent studies report that children from migrant communities are at higher risk of AUT than children born to non-migrant mothers, with the exception of Hispanic children. This paper provides the first systematic review into prevalence and predictors of AUT with a particular focus on maternal migration stressors and epigenetic risk factors. AUT rates appear higher in certain migrant communities, potentially relating to epigenetic changes after stressful experiences. Although AUT remains a rare disorder, failures to recognize its public health urgency and local community needs continue to leave certain cultural groups at a disadvantage.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
