AUTISM AND URBANIZATION - A SYSTEMATIC REVIEW

Introdução

Is there a relation between autism spectrum disorder (ASD) prevalence and urbanization?
A lot of studies have been published about this topic since the decade of 1980. There are 3 systematic reviews about this topic in the medical literature so far: two restricted to the Indian and Chinese population and one published in 2005 envolving studies from different countries.
There is data pointing to the tendence of autism being more prevalent in the urbanised areas, however this is not a defined topic in the medical literature yet. This systematic review aims to explore this association with the analysis of journal articles published from 2005 on.

Objetivo

This study aims to review the existent literature from 2005 on regarding the association between autism and urbanization and answer the question:
Is the prevalence of autism higher in urbanized areas?
