Time trends in autism diagnosis over 20 years: a UK population-based cohort study / Ginny RUSSELL in Journal of Child Psychology and Psychiatry, 63-6 (June 2022)
[article]
Titre : Time trends in autism diagnosis over 20 years: a UK population-based cohort study Type de document : Texte imprimé et/ou numérique Auteurs : Ginny RUSSELL, Auteur ; Sal STAPLEY, Auteur ; Tamsin NEWLOVE-DELGADO, Auteur ; Andrew SALMON, Auteur ; Rhianna WHITE, Auteur ; Fiona WARREN, Auteur ; Anita PEARSON, Auteur ; Tamsin FORD, Auteur Article en page(s) : p.674-682 Langues : Anglais (eng) Mots-clés : Autism autism spectrum disorder clinical practice research datalink diagnosis primary care time trends Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorder is a diagnosis that is increasingly applied; however, previous studies have conflicting findings whether rates of diagnosis rates continue to grow in the UK. This study tested whether the proportion of people receiving a new autism diagnosis has been increasing over a twenty-year period, both overall and by subgroups. METHOD: Population-based study utilizing the Clinical Practice Research Datalink (CPRD) primary care database, which contains patients registered with practices contributing data to the CPRD between 1998 and 2018 (N=6,786,212 in 1998 to N=9,594,598 in 2018). 65,665 patients had a diagnosis of autism recorded in 2018. Time trend of new (incident) cases of autism diagnosis was plotted for all, and stratified by gender, diagnostic subtypes, and developmental stage: infancy and preschool, 0-5?years old; childhood, 6-11?years old; adolescence, 12-19?years old; adults, over 19?years old. RESULTS: There was a 787%, exponential increase in recorded incidence of autism diagnoses between 1998 and 2018; R(2) =0.98, exponentiated coefficient=1.07, 95% CI [1.06, 1.08], p?.001. The increase in diagnoses was greater for females than males (exponentiated interaction coefficient=1.02, 95% CI [1.01, 1.03], p?.001) and moderated by age band, with the greatest rises in diagnostic incidence among adults (exponentiated interaction coefficient=1.06, 95% CI [1.04, 1.07], p?.001). CONCLUSIONS: Increases could be due to growth in prevalence or, more likely, increased reporting and application of diagnosis. Rising diagnosis among adults, females and higher functioning individuals suggest augmented recognition underpins these changes.

The following trends were observed: (1) a rise in referrals including an increase in referrals among language-abled children, (2) an increase in children assigned an ASD diagnosis after assessment, and (3) a decrease in Autism Diagnostic Observation Schedule total score. The distribution of ASD subtypes and IQ level did not change. Results suggest that a higher proportion of children with less severe autism symptoms were referred and diagnosed. Further, restricted and repetitive behaviors seemed to be a key discriminating factor when distinguishing between ASD and no-ASD children with a discordant symptom profile.

Inclusive and narrow research definitions of ASD (ASD-RI and ASD-RN, respectively) were explored, along with clinical diagnoses of ASD (ASD-C) obtained from the records. The incidence of ASD-RI, ASD-RN, and ASD-C increased significantly from 1985 to 1998, then ASD-RI and ASD-RN plateaued while the rate of ASD-C continued to increase during 1998-2004. The rising incidence of research-defined ASD may reflect improved recognition and documentation of ASD signs and symptoms. Although the frequency of threshold ASD symptoms stabilized, the rate of ASD-C continued to increase, narrowing the gap between clinical ascertainment and symptom documentation.

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.

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.
