Associations Between Perceived Social Support, Perceived Competence, and Physical Activity in Hong Kong Children With Disabilities During the COVID-19 Pandemic.

This study aimed to examine the associations between perceived social support, perceived competence, and physical activity in children with physical and intellectual disabilities during the COVID-19 pandemic. During the third wave of the pandemic in Hong Kong (i.e., July through December 2020), 291 participants age 6-17 years from 27 special schools were included. After controlling for demographic variables, the total variance explained by perceived social support and perceived competence was 24%, F(2, 240) = 12.42, p < .001, with perceived competence having a stronger association with physical activity (ß = 0.29, p < .001) than perceived social support (ß = 0.07, p = .22). This study highlights two key facilitators for shaping physical activity involvement among children with disabilities during the COVID-19 pandemic.

The Associations Between Accelerometer-Measured Physical Activity Levels and Mental Health in Children and Adolescents with Intellectual Disabilities During the COVID-19 Pandemic.

To examine the associations between physical activity (PA) levels and mental health in children and adolescents with intellectual disabilities (IDs) during the COVID-19 pandemic, 117 participants aged between 6 and 17 years with IDs from 10 Hong Kong special schools were included. There were positive dose-response associations between PA (i.e., light PA, moderate PA, and vigorous PA) and mental health, and participants with higher levels of moderate-to-vigorous PA (MVPA) and self-concept (SC) had better social quality of life (QoL) than those with lower levels of MVPA and SC. Moreover, personal and environmental factors such as age, body mass index, school, sex, ID level, and parental education level influenced the PA levels and QoL in children and adolescents with IDs.
