Despite this reality, there has been relatively little priority placed on promoting positive trajectories of health in either of these underserved populations. The primary purpose of this study was to examine the impact of participation in a 12-month, longitudinal health promotion program designed for both autistic children and their parent. A total of 27 families participated in the intervention, including 29 autistic children (83% male, M?=?8.28?+?3.60?years) and 27 parents (93% female, M?=?40.04?+?7.95). Families attended in-person health promotion programming for 90?min per week. Children and parents were evaluated at four time points across the program, including baseline (0-months), 4-months, 8-months, and 12-months. Children were measured on fundamental motor competence, physical fitness, body composition, and proxy-reported physical activity. Parents were measured on body composition, physical fitness, and self-reported physical activity. Significant improvements were observed for autistic children in motor competence (p?0.001) and grip strength (p?=?0.006), and for parents in body mass index (p?=?0.004) and aerobic capacity (p?=?0.003) across the 12-month intervention. Differing trajectories of improvement were noted between urban- and suburban-dwelling families on multiple outcomes. The knowledge acquired from this research may offer initial support for the need to bolster opportunities for accessible and ongoing health promotion programs for both autistic children and their parents.

Titre : The relationship among early functional milestones and core deficits in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : L. R. KETCHESON, Auteur ; E. A. PITCHFORD, Auteur ; Chandler F. WENTZ, Auteur Article en page(s) : 101638 Langues : Anglais (eng) Mots-clés : Motor impairment Functional skills Early intervention Core deficits Index. décimale : PER Périodiques Résumé : Background Autism Spectrum Disorder (ASD) is now the highest among the developmental disabilities in the United States, with recent statistics estimates of 1 in every 54 children. While growing attention on the early intervention services is warranted, what is not well understood is the relationship between the core deficits of ASD and the early functional skills in young children with ASD. Objectives The primary objective of this study was to determine the relationship between early developmental functional skills and behavioral outcomes in the core deficits of ASD. The secondary objective was to determine if the onset of early developmental functional milestones were related to age of diagnosis. Methods The current study is a secondary data analysis of the Simons Foundation Powering Autism Research for Knowledge cohort from the Simons Foundation Research Initiative (SFARI). Study objectives were examined using multiple linear regression analyses. To address the first objective, independent analyses were conducted for each behavioral subscale (Communication, Repetitive Behavior, Atypical Behavior, Social Reciprocity, and Peer Interaction). For the second objective a linear regression analysis was conducted to determine the relationship between core deficits and age of diagnosis. Results Multiple early functional milestones were significantly associated with current communication deficits, including the month of first independent walking (b = 0.11, p = .03), using words (b = -0.05, p = .02), and using combined phrases (b = 0.20, p < .001). However, the child's current age was the strongest predictor of current communication deficits (b = -0.53, p <. 001). The other core ASD deficit domains (i.e., Repetitive Behavior, Atypical Behavior, Social Reciprocity, and Peer Interaction) also had multiple significant associations with early functional milestones, but variance explained was negligible (R2 = 0.02?0.05). In terms of the second objective, significant predictors of the age of ASD diagnosis (in order of average attainment) included: month of first reported smiling (b = - 0.17, p = .007), walking (b = 0.24, p = .002), use of combined words (b = -0.10, p = .02), combined phrases (b = -0.40, p < .001), bladder-trained (b = -0.07, p = .03), and bowel-trained (b = -0.17, p <.001). Conclusion This study represents one of the first attempts at examining relationships among the acquisition of early functional milestones and outcomes in children with ASD. The current study may provide critical information related to the screening, diagnosis and intervention prescription for young children with ASD.

Titre : The Relationship Between Developmental Coordination Disorder and Concurrent Deficits in Social Communication and Repetitive Behaviors Among Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Leah R. KETCHESON, Auteur ; E. Andrew PITCHFORD, Auteur ; Chandler F. WENTZ, Auteur Article en page(s) : p.804-816 Langues : Anglais (eng) Mots-clés : core deficits intellectual disability motor abilities motor behavior motor coordination Index. décimale : PER Périodiques Résumé : Children with Autism Spectrum Disorder (ASD), characterized by core deficits in social communication and restrictive behaviors, can exhibit concurrent motor incoordination and/or intellectual disability (ID). While pervasive delays in motor behavior are common, formal diagnosis of Development Coordination Disorder (DCD) is uncommon. It is not clear how DCD and ID impact core deficits in ASD. This study utilized the Simons Foundation SPARK cohort to describe the scope of motor incoordination among children with ASD and examine the interrelationships between DCD risk, ID, and ASD core deficits. 10,234 children with ASD, between the ages of 5 and 15?years, were included in the analysis. Parents completed online versions of the DCD Questionnaire (DCD-Q), Social Communication Questionnaire (SCQ) and Restrictive Behavior Scale (RBS-R). 85% of children with ASD had DCD-Q scores consistent with being at-risk for DCD, but only 14% reported a formal diagnosis. Children with ID exhibited significantly greater motor incoordination compared to children without ID (P?0.001). Significantly, greater core deficits were identified in both children at-risk for DCD (P?0.001) and with ID (P?0.001). However, the effects of DCD risk were independent of ID and exhibited a medium effect size for SCQ (?(2) (p) = 0.063) and a small effect size for RBS-R (?(2) (p) = 0.04) scores. Collectively, study outcomes reinforce the pervasiveness of motor incoordination among children with ASD, both with and without concurrent ID, and provide further justification for the inclusion of motor behavior in the early intervention and prescription for children with ASD. LAY SUMMARY: This secondary data analysis of the Simons Foundation SPARK cohort found high rates (85%) of DCD risk among children with ASD. Deficits in motor coordination were greater among children with ASD with concurrent ID diagnoses. Meaningful differences in ASD core deficits (social communication and repetitive behaviors) were independently found in children at risk for DCD, both with and without ID.
