General social support and physical activity: an analysis of the Ontario Health Survey.

In spite of the many benefits of regular physical activity, the majority of Canadians are sedentary. This paper examines the relationship between general social support and physical activity levels. An analysis of data on 29,135 individuals from the 1990 Ontario Health Survey was conducted. Hierarchical multiple regression was used to determine the relationship between measures of general social support, derived from factor analysis, and physical activity levels. Sociodemographic and perceived health status measures were included as control variables. The results showed that general social support, in the form of Social Quantity and Social Frequency (number of friends/family members and frequency of contact), was significantly associated with higher levels of physical activity. Conversely, support in the form of Familial Structure (marital/cohabitation and parental status) was significantly associated with lower levels of physical activity. The findings indicate the types of general social support that facilitate or hinder participation in physical activity.
