Physical activity and salivary serotonin levels among children with or without autism spectrum disorders: A comparative cross-sectional study / Sima DASTAMOOZ in Research in Autism, 133 (May 2026)

Physical activity (PA) can influence peripheral serotonin. However, the relationship between PA and salivary serotonin in children and adolescents with ASD remains unclear. Accordingly, we compared salivary serotonin, PA, and sedentary behavior (SB) in children and adolescents with ASD versus typically developing (TD) peers, assessed PA and serotonin associations within each group, and examined whether findings varied across DSM-5 autism severity levels (1−3). Methods In a multi-center cross-sectional study in Iran, salivary serotonin (ELISA) and parent-proxy PA (International Physical Activity Questionnaire) were assessed in children and adolescents with ASD (n = 62; DSM-5 severity levels 1–3) and TD peers (n = 16), aged 5–13 years. Group differences were evaluated using Mann–Whitney U tests, and associations between PA, SB, and serotonin were examined using robust regression. Results Children and adolescents with ASD had higher salivary serotonin than TD (160 ± 94.3 vs 81.8 ± 40.6 pg. ml−1; p = 0.001). Compared with TD, children and adolescents with ASD reported lower walking, moderate activity, and lower sitting time. PA indices were not correlated with salivary serotonin in either group, or outcomes did not differ across ASD severity levels. Discussion Findings support altered peripheral serotonergic functioning in ASD and suggest that differences in reported PA do not explain salivary serotonin variation. Longitudinal and device-based activity assessments are warranted.

Physical activity and screen time among youth with autism: A longitudinal analysis from 9 to 18 years / J. DAHLGREN in Autism, 25-4 (May 2021)  

Public ISBD [article]  inAutism > 25-4 (May 2021) . - p.1090-1099 Titre : Physical activity and screen time among youth with autism: A longitudinal analysis from 9 to 18 years Type de document : texte imprimé Auteurs : J.

Longitudinal studies are needed to examine how physical activity and screen time behaviors co-develop for children with and without an autism spectrum disorder. To address this research gap, this study compared how physical activity and screen time levels changed over time (from 9 to 18 years of age) between youth with autism spectrum disorder and youth with neurotypical development. Data on the levels of moderate-to-vigorous physical activity, light physical activity, television-, and video game-based screen time, collected as a part of the "Growing up in Ireland" study, were compared between youth with autism spectrum disorder and a propensity-matched sample of youth with neurotypical development (n = 88 per group; 176 in total). Robust regression analyses indicated that children with autism spectrum disorder became less active over time compared to children with neurotypical development and that video game screen time also differed significantly between the groups when children were 9 years old. These findings elucidate important disparities present between these groups of children during pivotal developmental times.

Physical activity and self-determined motivation of adolescents with and without autism spectrum disorders in inclusive physical education / Chien-Yu PAN in Research in Autism Spectrum Disorders, 5-2 (April-June 2011)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 5-2 (April-June 2011) . - p.733-741 Titre : Physical activity and self-determined motivation of adolescents with and without autism spectrum disorders in inclusive physical education Type de document : texte imprimé Auteurs : Chien-Yu PAN, Auteur ; Chia-Liang TSAI, Auteur ; Chia-Hua CHU, Auteur ; Kai-Wen HSIEH, Auteur Année de publication : 2011 Article en page(s) : p.733-741 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Physical activity  Motivation  Adolescents Index. décimale : PER Périodiques Résumé : The main purpose of this study was to compare the objectively measured physical activity (PA) and the motivation process between adolescents with (n = 25) and without (n = 75) autism spectrum disorders (ASD) in inclusive physical education (PE); and assess the associations of the PA levels to a sequence of motivational processes. Independent t-tests revealed significant PA and motivational process differences between adolescents with and without ASD. External regulation was positively correlated with the percentage of time that adolescents with ASD spent in moderate PA (r25 = 0.58, p < .01) and moderate-to-vigorous PA (r25 = 0.50, p < .05), and this extrinsic motive was associated with their needs of being attached or related in the class (r25 = 0.53, p < .01). No significant associations of PA in PE on the motivational sequences of adolescents without ASD were observed. It is concluded that adolescents with ASD had less PA levels in PE and lower motives toward PE than adolescents without ASD, and external regulation was important in facilitating PA participation in adolescents with ASD.

Physical activity during the segmented school day in adolescents with and without autism spectrum disorders / Chien-Yu PAN in Research in Autism Spectrum Disorders, 15-16 (July 2015)

The PA of 60 male students (ASD, n = 30; TD, n = 30) was recorded every 10 s for up to 5 school days by performing uniaxial accelerometry. The main results are listed as follows: (a) daily PA was significantly lower among the students with ASD than among the TD students; (b) students with ASD spent significantly lower proportion of their time in moderate PA than TD students did during physical education (PE), recess, and lunchtime; and (c) fewer students with ASD than TD students achieved the PA guidelines during the school day and PE time. Schools should increase PA opportunities across the school day.

Physical activity in young adults with autism spectrum disorder: Parental perceptions of barriers and facilitators / Chad NICHOLS in Autism, 23-6 (August 2019)

The physical activity behaviors among adults on the autism spectrum are largely unexplored. It is presumed that sedentary behavior and obesity are a greater health issue among young adults on the autism spectrum who no longer receive Individuals with Disabilities Education Act services and supports such as school-based physical education. Using a phenomenology approach, the parents of eight young adults on the autism spectrum were interviewed about their perceptions of the barriers and facilitators to getting their young adults on the autism spectrum physically active. The purpose of this study was to investigate parent's perspective of physical activity barriers and facilitators of their adult children on the autism spectrum. Common themes of both physical activity barriers and facilitators included parents, behaviors associated with autism spectrum disorder, and access and opportunities.
