Accelerometer-measured physical activity levels in children and adolescents with autism spectrum disorder: A systematic review

Highlights

• Only 42% of them met the minimum WHO PA guideline.

• Younger age and better fitness, motivation and sleep were associated with higher PA.

• HH Having support from peers with TD, teachers and family were related to increased PA.

• Unprepared PE and lacking equipment were associated with decreased PA at school.

• Lack of community-based PA opportunities during leisure time were related to low PA.

• Policies or laws were not associated with PA.

Abstract

Associations between physical activity (PA) and health benefits are well documented. Evidence indicates that children and adolescents with autism spectrum disorder (ASD) are less physically active than their typically developing peers. The purpose of this systematic review is to provide a comprehensive summary of the PA levels of children and adolescents with ASD and the associated factors that affect their PA levels by applying a socio-ecological model (SEM). Seven databases (PubMed, CINAHL, SPORTDiscus with Full Text, MEDLINE, EMBASE, ERIC, and PsychINFO) were searched in June 2019 to identify studies examining accelerometer-measured PA and factors affecting the PA levels of children and adolescents with ASD, aged 6–17 years. Two researchers independently screened studies, assessed methodological quality, and summarized relevant data. Twenty-one studies were included in the detailed review. Only 42% of the participants met the PA guidelines (i.e., children and adolescents aged 5–17 years should do at least 60 min of moderate to vigorous PA daily). By applying the SEM, multi-level factors ranging from intrapersonal to community levels that positively or negatively influenced PA levels in children and adolescents with ASD were identified. This review indicates that children and adolescents with ASD have low PA levels, and that there are multi-level factors that affect their PA. There is a pressing need to design effective PA interventions that promote activity accrual in the school, family, and community settings for children and adolescents with ASD.
