Context Matters: Examining children's perceived barriers to physical activity across varying Canadian environments

Children's perceptions of their environment have been associated with their physical activity (PA) levels, however a better understanding of the formation of perceptions within different contexts is needed. This will help to inform decision making related to physical inactivity trends in Canadian children. We examined socio-ecological factors influencing children's perceptions of barriers to PA in Ontario, Canada. Binary logistic regression models measured the relationship between perceptions of barriers and PA for 892 children in Ontario. At the intrapersonal level, girls reported the most barriers to PA. Interpersonally, children whose mother was employed reported the most barriers. At the physical environment level, children in urban and suburban neighbourhoods of large cities, and rural areas reported the most barriers, differing relative to population size. The major contribution of this paper is a new perspective of environmental influences on children's perceptions of PA, using an urbanicity spectrum, and highlighting place specific needs of Canadian children.
