Physical activity patterns in youth with autism spectrum disorders

Area of Science:

• Pediatrics
• Neurodevelopmental Disorders
• Behavioral Science

Background:

• Autism Spectrum Disorder (ASD) is a neurodevelopmental condition affecting social interaction and communication.
• Understanding physical activity patterns in youth with ASD is crucial for promoting overall health and well-being.
• Age-related changes in physical activity levels are not well-characterized in this population.

Purpose of the Study:

• To investigate age-related differences in physical activity among youth with Autism Spectrum Disorder.
• To identify patterns of physical activity across different age groups and time periods.

Main Methods:

• A cohort of 30 youth (aged 10-19 years) diagnosed with ASD participated in the study.
• Participants were divided into three age-based groups: elementary, middle, and high school students.
• Objective physical activity data were collected using accelerometers over seven consecutive days, supplemented by activity questionnaires.

Main Results:

• Elementary school-aged youth with ASD exhibited significantly higher physical activity levels compared to middle and high school groups.
• Physical activity levels did not show consistent patterns based on the day of the week or time of day across all participants.
• A notable decline in physical activity was observed with increasing age within the studied adolescent population.

Conclusions:

• Physical activity significantly decreases in adolescents with Autism Spectrum Disorder as they transition through school years.
• Current interventions may not adequately support sustained physical activity engagement during adolescence for youth with ASD.
• Future interventions should prioritize the development and promotion of extracurricular physical activity opportunities tailored for adolescents with ASD to combat sedentary behavior.
