Age at autism spectrum disorder diagnosis: A systematic review and meta-analysis from 2012 to 2019 / Maarten VAN 'T HOF in Autism, 25-4 (May 2021)  

Public ISBD [article]  inAutism > 25-4 (May 2021) . - p.862-873 Titre : Age at autism spectrum disorder diagnosis: A systematic review and meta-analysis from 2012 to 2019 Type de document : texte imprimé Auteurs : Maarten VAN 'T HOF, Auteur ; Chanel TISSEUR, Auteur ; Ina VAN BERCKELEAR-ONNES, Auteur ; Annemyn VAN NIEUWENHUYZEN, Auteur ; Amy M.

ESTER, Auteur Article en page(s) : p.862-873 Langues : Anglais (eng) Mots-clés : age at diagnosis  autism spectrum disorder  influencing factors  meta-analysis  review Index. décimale : PER Périodiques Résumé : We currently assume that the global mean age at diagnosis of autism spectrum disorder ranges from 38 to 120 months. However, this range is based on studies from 1991 to 2012 and measures have since been introduced to reduce the age at autism spectrum disorder diagnosis. We performed a systematic review and meta-analysis (statistical analysis that combines the results of multiple scientific studies) for studies published between 2012 and 2019 to evaluate the current age at autism spectrum disorder diagnosis. We included 56 studies that reported the age at diagnosis for 40 countries (containing 120,540 individuals with autism spectrum disorder). Results showed the current mean age at diagnosis to be 60.48 months (range: 30.90-234.57 months) and 43.18 months (range: 30.90-74.70 months) for studies that only included children aged ⩽10 years. Numerous factors that may influence age at diagnosis (e.g. type of autism spectrum disorder diagnosis, additional diagnoses and gender) were reported by 46 studies, often with conflicting or inconclusive results. Our study is the first to determine the global average age at autism spectrum disorder diagnosis from a meta-analysis. Although progress is being made in the earlier detection of autism spectrum disorder, it requires our constant attention.

This study investigated whether the median age at diagnosis in childhood has reduced in recent years, and identified the factors associated with earlier diagnosis in the UK. Data on 2134 children with ASD came from two large family databases. Results showed that the age of ASD diagnosis has not decreased. The median age of diagnosis of all ASDs was 55 months. Factors associated with earlier age of diagnosis were autism diagnosis (compared with other ASD), language regression, language delay, lower socioeconomic status, and greater degree of support required. Effective clinical strategies are needed to identify children with characteristics that have in the past delayed ASD diagnosis.

Gender differences in parent-reported age at diagnosis of children with autism spectrum disorder / Alexandra M. PETROU in Research in Autism Spectrum Disorders, 50 (June 2018)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 50 (June 2018) . - p.32-42 Titre : Gender differences in parent-reported age at diagnosis of children with autism spectrum disorder Type de document : texte imprimé Auteurs : Alexandra M. PETROU, Auteur ; Jeremy R. PARR, Auteur ; Helen MCCONACHIE, Auteur Année de publication : 2018 Article en page(s) : p.32-42 Langues : Anglais (eng) Mots-clés : Autism  ASD  Girls  Gender  Age at diagnosis Index. décimale : PER Périodiques Résumé : Background Autism spectrum disorders (ASD) are more commonly observed in boys than in girls. There is growing awareness of ASD in girls and recognition that under-diagnosis is common. The current study aimed to investigate any evidence of reduction in the average age at diagnosis for girls by assessing whether: 1) girls’ age at diagnosis has reduced, compared to boys’, across two age cohorts – children born between 1996–1999 and 2002–2005; 2) age at diagnosis differed between boys and girls diagnosed across childhood; 3) any characteristics are associated with earlier age at diagnosis in girls. Methods Data were available from large UK databases of children with ASD: The Database of Children with Autism Spectrum Disorder Living in the North East (http://daslne.org) and the Autism Spectrum Database–UK (www.asd-uk.com). Results There was no differential reduction of parent-reported age at diagnosis for girls over time. For children receiving their diagnosis at age ≥60 months, boys received diagnoses an average of one year earlier than did girls (98.2 months, SD = 31.6 vs. 109.1 months, SD = 36.4). For boys and girls, earlier diagnosis was associated with toileting problems and temper problems. Having additional diagnoses (e.g., dyslexia, dyspraxia, and epilepsy) was associated with later diagnosis. Conclusions Age at diagnosis has not decreased over time. Girls with ASD are diagnosed later than boys when aged 5 years or older. Health and education professionals would benefit from better understanding factors such as toileting problems, temper problems, and additional diagnoses that could potentially guide early identification of ASD in clinical practice for school-age girls.

The Effects of Early Language on Age at Diagnosis and Functioning at School Age in Children with Autism Spectrum Disorder / Anthony GOODWIN in Journal of Autism and Developmental Disorders, 47-7 (July 2017)

However, the predictive utility of language milestones relative to co-varying factors such as age at diagnosis, IQ, and ASD symptomatology is unclear. This study compared school-aged children with ASD and NLD (n = 59) to a well-matched group with ASD and LD (n = 59). The LD group was diagnosed at younger ages and their historical ASD symptoms were more severe than the NLD group. The groups were similar in current ASD symptoms and adaptive functioning at school age. Language milestones were correlated with adaptive functioning, but IQ and social symptoms of ASD were stronger predictors of functioning at school age. Therefore, language milestones may not be the best indicators of prognosis for children who are diagnosed after toddlerhood.

Understanding autism diagnosis in primary care: Rates of diagnosis from 2004 to 2019 and child age at diagnosis / Jessica V. SMITH in Autism, 28-10 (October 2024)  

Public ISBD [article]  inAutism > 28-10 (October 2024) . - p.2637-2646 Titre : Understanding autism diagnosis in primary care: Rates of diagnosis from 2004 to 2019 and child age at diagnosis Type de document : texte imprimé Auteurs : Jessica V. SMITH, Auteur ; Michelle MENEZES, Auteur ; Sophie BRUNT, Auteur ; Jessica PAPPAGIANOPOULOS, Auteur ; Eleonora SADIKOVA, Auteur ; Micah O MAZUREK, Auteur Article en page(s) : p.2637-2646 Langues : Anglais (eng) Mots-clés : age at diagnosis  autism  capacity-building  diagnostic timing  early identification  primary care Index. décimale : PER Périodiques Résumé : The capacity of the workforce lags behind the current demand for timely autism diagnostic assessment. Primary care providers (PCPs) are well-positioned to diagnose autism at earlier ages than providers from other disciplines. Thus, bolstering PCPs' diagnostic capabilities has been the focus of many recent capacity-building initiatives. Using data from the National Survey of Children s Health, this study aimed to evaluate whether diagnosis of autism in primary care has changed over time and whether diagnosis in primary care relates to age at autism diagnosis. Results indicated that the likelihood of being diagnosed with autism by a PCP decreased by about 2% with every passing year from 2004 to 2019 when controlling for demographic characteristics. PCPs diagnosed children approximately 1 year earlier than non-PCPs (e.g., psychiatrists and psychologists), which supports the critical role PCPs can play in timely diagnosis. Further research is needed to understand why the proportion of children diagnosed by PCPs has decreased over time; however, these findings suggest that capacity-building initiatives have not yet reached community practice. Future research should focus on the dissemination and implementation of training initiatives in community-based primary care practices. Lay abstract The current demand for autism diagnostic services exceeds the ability of the workforce to assess and diagnose children in a timely manner. One solution may be to equip primary care providers (PCPs) with the tools and expertise needed to diagnose autism within their practice. PCPs are often trusted professionals who have many touchpoints with children during early development, in which they can identify early signs of autism. Recent initiatives have focused on bolstering PCPs' diagnostic capabilities; however, no studies have examined how the rates of autism diagnosis in primary care have changed over time. We aimed to evaluate whether autism diagnosis in primary care has changed over time and how diagnosis in primary care relates to a child?s age at the time of diagnosis. We found that the likelihood of a child being diagnosed by a PCP decreased by about 2% with every passing year from 2004 to 2019 when accounting for demographic characteristics. In our sample, PCPs diagnosed children approximately 1 year earlier than non-PCPs (e.g., psychologists and psychiatrists). Further research is needed to understand why the proportion of children diagnosed by PCPs decreases over time. However, this decrease suggests more work is needed to get capacity-building initiatives into community primary care practice. Though we must continue to find effective ways to build community PCPs' ability to diagnose autism, the present findings support the crucial role PCPs can play in early autism diagnosis.
