Trends in developmental disabilities in pediatrics
RESULTS: From 2009 to 2011 and 2015 to 2017, there were overall significant increases in the prevalence of any developmental disability (16.2%–17.8%, P < .001), attention-deficit/hyperactivity disorder (8.5%–9.5%, P < .01), autism spectrum disorder (1.1%–2.5%, P < .001), and intellectual disability (0.9%–1.2%, P < .05), but a significant decrease for any other developmental delay (4.7%–4.1%, P < .05). The prevalence of any developmental disability increased among boys, older children, non-Hispanic white and Hispanic children, children with private insurance only, children with birth weight ≥2500 g, and children living in urban areas and with less-educated mothers.
CONCLUSIONS: The prevalence of developmental disability among US children aged 3 to 17 years increased between 2009 and 2017
