Model inputs include ASD prevalence, census population projections, six cost categories, ten age brackets, inflation projections, and three future prevalence scenarios. Future ASD costs increase dramatically: total base-case costs of $223 (175-271) billion/year are estimated in 2020; $589 billion/year in 2030, $1.36 trillion/year in 2040, and $5.54 (4.29-6.78) trillion/year by 2060, with substantial potential savings through ASD prevention. Rising prevalence, the shift from child to adult-dominated costs, the transfer of costs from parents onto government, and the soaring total costs raise pressing policy questions and demand an urgent focus on prevention strategies.

California Autism Prevalence by County and Race/Ethnicity: Declining Trends Among Wealthy Whites / Cynthia NEVISON in Journal of Autism and Developmental Disorders, 50-11 (November 2020)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 50-11 (November 2020) . - p.4011-4021 Titre : California Autism Prevalence by County and Race/Ethnicity: Declining Trends Among Wealthy Whites Type de document : texte imprimé Auteurs : Cynthia NEVISON, Auteur ; William PARKER, Auteur Article en page(s) : p.4011-4021 Langues : Anglais (eng) Mots-clés : Asian  Autism spectrum disorder  Black  California  County  Hispanic  Income  Prevalence  Race/ethnicity  Silicon Valley  Time trends  White  or financial relationships that could be construed as a potential conflict of  interest. Index. décimale : PER Périodiques Résumé : County-level ASD prevalence was estimated using an age-resolved snapshot from the California Department of Developmental Services (DDS) for birth years 1993-2013. ASD prevalence increased among all children across birth years 1993-2000 but plateaued or declined thereafter among whites from wealthy counties. In contrast, ASD rates increased continuously across 1993-2013 among whites from lower income counties and Hispanics from all counties. Both white ASD prevalence and rate of change in prevalence were inversely correlated to county income from birth year 2000-2013 but not 1993-2000. These disparate trends within the dataset suggest that wealthy white parents, starting around 2000, may have begun opting out of DDS in favor of private care and/or making changes that effectively lowered their children's risk of ASD.

California Autism Prevalence Trends from 1931 to 2014 and Comparison to National ASD Data from IDEA and ADDM / Cynthia NEVISON in Journal of Autism and Developmental Disorders, 48-12 (December 2018)

The data are consistent across methods in showing a strong upward trend over time. The prevalence of autism in the CDDS dataset, the longest of the three data records, increased from 0.001% in the cohort born in 1931 to 1.2% among 5 year-olds born in 2012. This increase began around ~ 1940 at a rate that has gradually accelerated over time, including notable change points around birth years 1980, 1990 and, most recently, 2007.

Diagnostic Substitution for Intellectual Disability: A Flawed Explanation for the Rise in Autism / Cynthia NEVISON in Journal of Autism and Developmental Disorders, 47-9 (September 2017)

These trends did not support the hypothesis that diagnostic substitution for ID can explain the ASD rise over recent decades, although the hypothesis appeared more plausible when the data were aggregated across all states and ages. Nationwide ID prevalence declined steeply over the last two decades, but the decline was driven mainly by ~15 states accounting for only one-fourth of the U.S. school population. More commonly, including in the most populous states, ID prevalence stayed relatively constant while ASD prevalence rose sharply.

Race/Ethnicity-Resolved Time Trends in United States ASD Prevalence Estimates from IDEA and ADDM / Cynthia NEVISON in Journal of Autism and Developmental Disorders, 49-12 (December 2019)

White ASD prevalence historically has been higher than other racial groups but plateaued for IDEA birth cohorts from ~ 2004 to 2007 before resuming its increase. Black and Hispanic IDEA prevalence increased continuously and caught up to whites by birth year ~ 2008 and ~ 2013, respectively, with black prevalence subsequently exceeding white prevalence in the majority of states. Plateaus in white prevalence occurred in some ADDM states for birth years 2002-2006, but IDEA trends suggest prevalence will increase across all racial groups in ADDM's birth year 2008 report.
