Determinants and challenges in physical activity participation in families with children with high functioning autism spectrum disorders from a family systems perspective.

The underlying factors affecting physical activity (PA) participation of children with high-functioning autism spectrum disorders (HFASDs) and their family members were investigated using a mixed method research design. Six families with children with HFASD aged 4 through 13 participated in the study. Findings revealed that levels of moderate to vigorous physical activity (MVPA) in children with HFASD varied between 85 min and 405 min for seven days. Parents of children with HFASD in this study were inactive (levels of MVPA varied between 6 min and 53 min) during this period. Qualitative data from parents highlighted many essential issues. Those issues are categorized under three main themes: (a) understanding PA in children with HFASD, (b) living with a child with HFASD, and (c) awareness of autism spectrum disorders (ASD) at school and community settings. Social skills, issues related to bullying, fear of injury to the child, as well as support from family members and lack of understanding of the disability emerged as subthemes extracted from these data.
