Considering the specific manifestations of ASD in the eyes and the interconnectivity between the brain and the eyes, this study investigates ASD through the lens of retinal analysis. We specifically examined differences in the macular region of the retina using optical coherence tomography (OCT)/optical coherence tomography angiography (OCTA) images between children diagnosed with ASD and those with typical development (TD). Our findings present potential novel characteristics of ASD: the thickness of the ellipsoid zone (EZ) with cone photoreceptors was significantly increased in ASD; the large-caliber arteriovenous of the inner retina was significantly reduced in ASD; these changes in the EZ and arteriovenous were more significant in the left eye than in the right eye. These observations of photoreceptor alterations, vascular function changes, and lateralization phenomena in ASD warrant further investigation, and we hope that this work can advance interdisciplinary understanding of ASD.

Socioeconomic factors and autism among 16- to 30-month-old children: Evidence from a national survey of China / Muqing CAO in Autism, 27-5 (July 2023)  

Public ISBD [article]  inAutism > 27-5 (July 2023) . - p.1283-1294 Titre : Socioeconomic factors and autism among 16- to 30-month-old children: Evidence from a national survey of China Type de document : Texte imprimé et/ou numérique Auteurs : Muqing CAO, Auteur ; Li LI, Auteur ; Hein RAAT, Auteur ; Amy VAN GRIEKEN, Auteur ; Xin WANG, Auteur ; Lizi LIN, Auteur ; Qiang CHEN, Auteur ; Jin JING, Auteur Article en page(s) : p.1283-1294 Langues : Anglais (eng) Mots-clés : autism;socioeconomic factors;toddlers Index. décimale : PER Périodiques Résumé : We examined the association of socioeconomic status with the diagnosis of autism during 16-30?months of age. Using data from a national survey in China, we included 6049 children (55.6% male) in the final analysis, among which 71 of them were clinically diagnosed with autism. Adjusted for covariates, the odds ratios for having the diagnosis of autism (2.46, 95% confidence interval: [1.32, 4.59]) among children whose mother?s level is "junior middle school or below" were significantly higher than children whose mother?s level is "college or above." Among children of lower educated mothers, there is a higher risk of being diagnosed with autism at a young age. We recommend more support for families with a low socioeconomic status to early detect, diagnose, and manage autism. Lay abstract Does being born in a family of high socioeconomic status mean a higher risk of being diagnosed with autism? The evidence from the Asian area is lacking. This research was conducted among 6049 toddlers who went through an evaluation-diagnose procedure of autism and whose parents were surveyed during the national survey of China, 2016-2017. Parents reported their education levels, occupations, family income, and ethnic background. We recruited the toddlers and parents from kindergartens, communities, and hospitals in five geographically representative areas of China. On average, these toddlers were 23?months of age. We found toddlers whose mothers had less than 9?years of education (junior middle school or below) had 2.46 times the chance to get a diagnosis of autism, compared with toddlers whose mothers had more than 15?years of education (college or above). We also found that 1.17 toddlers could be diagnosed with autism in each 100 Chinese toddlers. These findings have important implications for providing support to families that have low socioeconomic status, especially families with a mother who did not complete 9?years of education. Early detection programs focused on children from low socioeconomic backgrounds should be promoted.

The validity and reliability of the simplified Chinese version of the Social Communication Questionnaire / Si-Yu LIU in Autism Research, 15-9 (September 2022)  

Public ISBD [article]  inAutism Research > 15-9 (September 2022) . - p.1732-1741 Titre : The validity and reliability of the simplified Chinese version of the Social Communication Questionnaire Type de document : Texte imprimé et/ou numérique Auteurs : Si-Yu LIU, Auteur ; Xin WANG, Auteur ; Qiang CHEN, Auteur ; Jia-Jie CHEN, Auteur ; Cheng-Kai JIN, Auteur ; Xiao-Ling ZHAN, Auteur ; Cui-Hua GUO, Auteur ; Xiu-Hong LI, Auteur ; Li-Zi LIN, Auteur ; Jin JING, Auteur Article en page(s) : p.1732-1741 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/diagnosis  Child  Child, Preschool  China  Communication  Humans  Psychometrics  Reproducibility of Results  Surveys and Questionnaires  Social Communication Questionnaire  autism spectrum disorder  reliability  validity Index. décimale : PER Périodiques Résumé : This study aims to validate the simplified Chinese version of the Social Communication Questionnaire (SCQ) in children aged 2-12years from both general and clinical populations. We recruited 819 Chinese children in this study, including 505 typically developing (TD) children, 202 children with autism spectrum disorder (ASD) and 112 children with non-ASD neurodevelopmental disorders. All the children's parents completed the simplified Chinese version of the SCQ and all children with ASD were additionally assessed for intelligence and the Childhood Autism Rating Scale to confirm their diagnosis. We have developed a 40-item, 4-factor structure of SCQ with two domains (social communication and social interaction; and restricted, repetitive, and stereotyped patterns of behavior), which showed adequate goodness of fit (comparative fit index [CFI] = 0.96, Tucker-Lewisindex [TLI] = 0.95, standardized root mean squared residual [SRMR] = 0.07, root mean square error of approximation [RMSEA] = 0.05), with good internal consistency (Cronbach's alpha = 0.92). We have provided different cut-offs to distinguish ASD cases from TD children (11 for children under 4years [sensitivity: 0.96, specificity: 0.95], 12 for children 4years and above [sensitivity: 0.93, specificity: 0.98]) or children with other neurodevelopmental disorders (14 [sensitivity: 0.85, specificity: 0.88]). Through this large sample validation, we confirmed that the simplified Chinese version of the SCQ could be used for children aged 2-12years with relatively good psychometric properties. LAY SUMMARY: We aimed to develop the simplified Chinese version of the Social Communication Questionnaire (SCQ) for Chinese children aged 2-12years as a screening tool to identified potential risk of autism spectrum disorder (ASD). We have developed a 40-item, 4-factor structure of SCQ with two domains, which showed adequate goodness of fit and good psychometric properties. We also provided different cut-offs to identify ASD cases in general or clinical populations.
